sql - Conditional limit in mySQL query possible? -

I am facing a decree about handling threaded comments in our project ... I have a simple All the comments which have the MySQL table There are two types: Parents and children children represent one answer to one parent or another child.

My problem:

- Comment (depth 0)
- Answer Children (Depth 1)
Answer to previous child Give (depth 2)
-Tiping (Depth 0)

Imagine the structure above and a MySQL query with my Linux 2. This is the last answer (depth 2) Actually I say something like this Would you like to try: Limit up to 2, if the child does not go to the next parent. Tried many questions with no luck ...

What I have just followed is as follows:
Select from SQL_CALC_FOUND_ROWS * Comments where comment_post_id = '{$ _REQUEST ["id "]} 'Comment_id by ORDER, comment_date DESC serious 10"

Important table fields are:
comment_id (index) | comment_parent_id (note of guardian or null is _ID) | comment_date

I'm very grateful

MySQL does not have any ideas!

< P> Work to parse structures like a tree. In the simplest scenario (the child's parent has an ID), you can revisit the program in an introductory manner to find all the sub-nodes in a given node. Maxwellwell wants to point you to the depth it decreases with each recurring call so that you end up with 0, which will stop the recurrence.

For example (Pseudo-code)

  findNodes (string par EntId, int maxLevel) (select from * positions, where parent = parent underwork (results ...) {if (maxLevel & gt; 0) {findNodes (result.nodeId, maxLevel-1)} doSomethingWIthAResult}} To do this in a more concise way, there are several techniques, all of which are indexed in some way The path in which the path of the current post is included, the path may look something like this: TopNode: Child1: Child2: Child3 ... in which you can do such a selection * Choose from the posts where the path like "TopNode%" and Depth = 2. 
 

Am I reinventing the wheel? PHP/Mysql User reigstration and payment processing -

I'm about a php / mysql platform code that does the following:

• Admin panel
• PayPal payment processing
• Paypal subscription handling through the API so that the user should not have a PayPal account

Is anything like that before Exists from what I can use?

If nothing is like this, then I'm going to refresh it in the Zend Framework, which I have never done before. If I go this route, then I do not want to search for some parts of what I am doing?

EDIT: Certainly this should be posted first:

Why do I need this forum just a basis for me to create a PHP web-based business application For customers who have to use monthly subscription. I'm looking for something very lightly, it's the only platform to register and manage membership and payers, not on the entire website. It will not have a store in an Oscars meaning.

optimization - PostgreSQL: How to optimize my database for storing and querying a huge graph -

I am running PostGrace SQL 8.3 with 1. GHG RAM and 1.83 GHz Intel Core Duo Mac Mini with Mac OS X 10.5.8 . . I have stored a huge graph in my PostgreSQL database, which has 1.6 million nodes and 30 million edges. My database schema is similar:

  Make Table Nodes (ID Integer Primary Key, Title VARCHAR (256)); Create table edges (ID integer, link integer, primary key (id, link)); Create index id_idx current edges (ID); Create index link_idx Create edges;  

Data is visible in table edges

  ID link 1 234 1 88865 1 6 2 365 2 12 ...  

So it stores the ID for each node, which is the link to exit from id y.

The time to find all outgoing links is fine:

  = # Analyze select links from edges where id = 4620; Question Scheme ------------------------------------------------ --------------------------------- Index scan ID_idx on edges (cost = 0.00..101.61 rows = 3067 width = 4) (real time = 135.507..157.982 rows = 1052 loops = 1) Index Conduit: (id = 4620) Total runtime: 158.348 ms (3 lines)  

However, if I come Searching for links in the node, the database is 100 times slower (although the resulting number of incoming links is only 5-10 times the number of outgoing links):

  = #in Analyze identity ID from where the link = 4620; Question Scheme ------------------------------------------------ ---------------------------------- Heap scan on bitmap edges (cost = 846.31..100697.48 rows = 51016 width = 4) (real time = 322.584..48 9 83.478 lines = 26887 loop = 1) Check again: (link = 4620) - & gt; Bitmap index scan link_ idx (cost = 0.00..833.56 rows = width of 51016 = 0) (real time = 298.132..298.132 rows = 26887 loop = 1) Index link: (link = 4620) Total runtime: 49001.936 MS (5 lines ))  

I tried not to use PostGrace with a bitmap scan

  = # set_autm_mapscan = false;  

But the speed of the query for the incoming link did not improve:

  = # Select ID from the edges where the link = 1588; Question Scheme ------------------------------------------------ ------------------------------------------- Using link_idx on index edges Scanned (cost = 0.00.4.4777.63 rows = 1143 width = 4) (real time = 110.302..51275.822 rows = 43629 loop = 1) Index link: (link = 1588) Total runtime: 51300.041 ms (3 lines) < / Code> 

I have increased my shared buffers from 24MB to 512 MB, but this did not help, so I wonder if the outgoing and incoming links My query to show an asymmetric behavior of this kind? Is anything wrong with indexed my choice? Or would I want to make a node with an ID ID better by creating a third table for all incoming links? But this would be quite a waste of disk space. But since I'm new to SQL Database, maybe I'm missing something fundamental?

I think that's right.

You can use it after filling the table. Now the second query should be sharp, and should be slow down first.

To keep both questions fast, you must denormalize using a second table, as you have proposed. Just remember the cluster and analyze this second table after loading your data, so all the examples associated with the node will be physically grouped.

If you will not be able to ask it all the time and you do not want to store and back up this second table, you can make it temporarily before you can inquire:

  Create a temporary table eg_des_backwards as the link, from the order of the edges ID; Create index edges_backwards_link_idx on edges_backwards (link);  

You do not need to cluster this temporary table, because it will be ordered physically directly on creation. This does not make any sense for a query, but can help for many queries in one line.

Azure CTP signup -

I am trying to signup in the Ezore CTP but the whole process is looking for real non user friendly. This web page gives me a link to get a token, but when I click it does not appear to do anything it takes me to another page but I do not know whether the token was sent Or I have to do something else

On the Microsoft connect's dashboard, it tells me that what is my position in Ezur 'Participating', what does that mean? I am not participating because I do not have tokens. The whole process is very disappointing!

Is it possible to contact a real person?

It looks like you've already submitted a request for a token. I tried to sign up a week ago and I have not got anything yet. However, I have received my SQL Exxoor license and it is working well.

Besides, you are perfectly right, their website is messy and things are very difficult to understand. I hope they will clean it soon!

And I do not think they have any support setup.

php - Preg matching and counting the resulting match in a short string -

I have a function that calculates the number of items in a string ($ paragraph) and tells me how many results There are letters, that is, spoon and spoon present 7, I can use it to complete the percentage of the string.

I need to reinforce it with preg_match because 10tsp should be calculated as 5.

$ letters = stellon ($ paragraph); $ Items = array ("toss", "tbsp", "tbs"); $ Count = 0; Calculate the number of formatting in foreign currency ($ item $ items) {// parameter $ countitems = substr_count ($ paragraph, $ item); $ Countlength = (strlen ($ item) * $ countitems); $ Count = $ count + $ countlength; } $ Composite = (($ 100 / $ character) * $ count);

I know that something like preg_match ('# [d] + [items] #', $ paragraph) will be something correct?

Sorry for the curve ball edit but there can be a place between numbers and $ items, can an example hold preg_match?

It's not quite clear to me that what you're trying to do with regex, but If you are just trying to match for a particular number-measurement combination, then it may help:

$ count = preg_match_all ('/ \ d + \ s * ( Tbsp | tsp | tbs) / ', $ paragraphs);

This will return the number of times, where a number-measurement combination occurs in the $ paragraph .

EDIT

  $ paragraph = "5tbsp and 10 teaspoons"; $ Charcnt = 0; $ Matches = array (); {Preg_match_all ('/ \ d + \ s * (tbsp | tsp | tbs) /', $ paragraph, $ matches) & gt; {foreach ($ matches [0] $ match) {$ charcnt + = Strlen (match $); }} Printf ("Total number of characters:% d \ n", $ charcnt);

php - How to extract an email address from multiple text files -

I have approximately 96 text emails for which I want to remove the sender's address. I believe that I can do this for domdoc I can use, but someone needs to start me Can someone please advise that there is a better way of doing this?

Thanks, Jim

There is no reason for PHP to do this. .. files are in some form of flat text, copy the file (s) (for example) email / directory, then

  cat * | Grep "From:" | Egrep -oi '\ b [A-Za-z0-9 ._% -] + @ [A-Za-z0-9 .-] + \. [A-Za-z] {2,4} '| Sort | Uniq & gt; Mail.list  

If you do this in PHP

1. Copy file / mail to a directory < / Li>
2. Get the list of files
3. Read the file
4. Split the header into a different string
5. Two an email address on this string To find and put it on $ email_arr
6. , array_unique () on $ email_arr.

bash - identify error in if statement -

This is a complete code ..

What am I trying to do ->

I am trying to find the average of values ​​in the second column of files. If the file has 2.54 names in it, then I want to get the file from average in files related to the file. File 054_even.xls and file_2.54_odd.xls. If there is no 2.54 on the name of Faynm, then just the average of the file is revealed. For example: file_1.60.xls

  #! / Bin / bash file in pmb_mpi tau xhpl mpi_tile_io fftw; For 2.54 1.60 800, if $ $ {f} = "2.54"] then $ {file} _ $ {f} _even_v1.xls esk 'yoga = $ 2; Ed {print "avg =", $ sum / nr> $ {File} _ $ {f} _avrg.xls} '$ {file} _ $ {f} _even_v1.xls resonant $ {file} _ $ {f} _odd_v1.xls awk' sum + = $ 2; END {print "average =", $ yoga / nr> gt; $ {File} _ $ {f} _avrg.xls} '$ {file} _ $ {f} _odd_v1.xls else echo $ {file} _ $ {f} _v1.xls awk' sum + = $ 2; END {print "average =", $ yoga / nr> gt; $ {File} _ $ {f} _avrg.xls} '$ {file} _ {f} _v1.xls foo  

Because your awk command is inside a single quotes, the shell variable file and f will not be be extended. That's why you are getting awk errors.

I will use the following script:

  #! PMBMP Tau XHPP MPI_Tile_OFFTV for file in / bin / bash; 2.54 For 1.60 f; If [[$ {F} = "2.54"] ;; Then flist = $ {file} _ $ {f} _even_v1.xls $ {file} _ $ {f} _odd_v1.xls and flists = $ {file} _ $ {f} _v1.xls fi $ {flist} | Awk 's + = $ 2; $ {File} _ $ {print "average =", $ s / nr} '& gt; Use $ {file} _ $ {f} _avrg.xls # or awk ... '$ {flist} & gt; F} _avrg.xls # If you are very worried about the efficiency of the procedures  f   2.54      < / Code>    / code> or not, then push the list of files through a single  awk  script. 
 

c# - Maintaining xml hierarchy (ie parent-child) information in objects generated by XmlSerializer -

For some time now I am trying to solve the following problem and I am starting to run away from ideas:

I have prepared a set of C # classes using Xsd.exe tool from XSD schema and dysfunctioning xmi files works fine. The problem is that besides the convenience and security of using auto-generated classes, I need information about the XML hierarchy, that is, I need to establish parental relationships between objects created during deserialization. Note that I want to avoid keeping a separate XML hierarchy structure (like a DOM tree), but keep track of the generated objects to keep track of your parents and children.

I have been able to shut it down in JAXB:

1. Define a common base class for all deserialized objects in this base class And the reference to the guardian object (if any) are included.

2. Using Unmarshaller. Listener Functionality Provides Callback on Full Object Deserialization This callback recently provides a reference to the parents of the deserialized object, which establishes maligning the parent's relationships.

How do I do this in C #? I have taken a look at the MSDN docs and made many goalkeepers, but there is no useful information available.

I wrote about this article some time ago, maybe it can help you.

linux - Display socket options -

How can I see from the shell how the socket options are set? Especially I find it interesting to know if SO_BROADCAST is set up?

You can use if the PID is the process id and < Code> FD is a file descriptor number of the socket of your interest, so you can:

  LSOF-A-P PID-D FD-T F /  
 To list all IPv4 sockets of a process:  
  LSOF-A-P PID - I 4 -T f  
 
 this will print the socket option with a  SO = , other go Note the officer that you do not set any options, you will be an empty string, so you'll see something like  SO = PQLEN = 0  etc. To test for  SO_BROADCAST , just type  SO =  after the string  SO_BROADCAST  for grep, for example 
 
  If lsof -a -p PID -d FD-T f | Grep -q 'SO = [^ =] * SO_BROADCAST'; So #Socket is SO_BROADCAST and #, it is not

c# - Database operation via Threadpool or Asyn programming -

I have a database with a large number of records. (Database value is updated through a webservice)

Each record / line type (ID, xmlfilename, operation, parameter, operation ID, status) means that the parameters of the operation specified by "parameter" With "xmlfilename" as specified in the 'xmlfile' operation as 'operation.' The part of the position is "intially" free as updated as reqd.

I want to use these (each line) operation threads .. The number of entries per 'id' per one thread. As long as there are 'id' rows in the DB bringing and "operation"

How can I do it efficiently with maximum equality and / or concurrency.

Is there any better way?

What is the best Threadpool or Custom Threads or ASIN programming?

Edit added: Here is the pseudo code that I tried

  string operation id = zero; While (operationId = DBWorker.getNextFreeOperationId ()) // How do I check this? Another query? Unless the position is operated with "Free" /, select Operation / Note DB. Updating Asynchronous {// Operation Id = Get all the rows with Operation ID eg: 800 1 thread / qid ??? ? And // condition = "free" ... // There are several operations with the same operation IDS DataRowCollection dbRows = DBWorker.retrieveQueuedEntries (operationId); MyWorkItem workItem = New DBWorker.MyWorkItem (); WorkItem.DataRows = DBRO; WorkItem.Event = new AutoResetEvent (wrong); //MyWorkItem.DoWork will require "Operation" ThreadPool.QueueUserWorkItem (New WaitCallback (workItem.DoWork), workItem); } -------------- MyWorkItem.DoWork (obj x) {// Summary for each DataRow row in this. DataRows {performOperation (line); // Usage line ["Operation"] ..} --------------- Display Bool Operation (date line) {string operation = (string) row ["operation"]; // Recover the other similar switch (operation) {Add Case Operations: // Add call operation .. ...}} ------------  

Using Code 2.2.0 .. does not receive multithreading .. The scenario may be that the database is updating asynchronously from one end, while the above code is running as a window service at the same time Will happen.

If you do not use .NET 4.0 Use Threadpool - I'll create a function that will get the line (if you change the rows, it would be better to type correctly for typed objects), and what to do with it -

  Using the system; Using System.Threading; Namespace SmallConsoleAppForTests {Class Program {Personal Static AutoResetEvent [] Events; Fixed zero main (string [] args) {int dataLength = 3; // Processing AutoResetEvent [] Events = New AutoResetEvent [dataLength] that has been made to create an array of AutoResetEvent; // Start the AutoResetEvent array in "no-set" values; For (int i = 0; i & lt; data lenthheth; i ++) events [i] = new autorsecurity (falls); // Processing for data (Int i = 0; i & lt; data length; i ++) {var data = new MyWareIT {event = events}, data = new MyDataClass ()}; Try ThreadPool.QueueUserWorkItem (x = & gt; {var dataItem = (MyWorkItem)}} {// Process on Data} {Exception E} {// Exception Handling} Finally {workItem.Event.Set ();} }, Data); } // Wait until all threads are finished. Wait. Wait (all); }} Public class MyWorkItem {public AutoResetEvent event {get; Set; } Public MyDataClass data {get; Set; If you are using .NET 4.0 - Check in Tasks and Parallel Extensions  

You can also use DatRov for public class {// data // }}

functional programming - Clojure: How to create a function at runtime -

I want to generate a fn entirely on the sequence (i.e. name and RGR symbols are ordered in sequence, Not in code) What is the best way to achieve this?

How can I implement the following functions?

  (defn gen-fn [name arg-symbols body] ... ...  

will be used like this:

  (Jean-FN "my-throw-name" (symbol "x") (symbol "y") (println "this  x =" x ")  

Note that the name, arg and body of the function are not coded, but the runtime can be decided

  (defn gen-fn [n as b] (let [n (symbol n) (vec as the map symbol)) fn-  

Some more uses:

Code> User => (Jean-F N "EFU" ["X"] '(print (XMP)) (printline (Ink))) #' User / FU user => (FU5) 5 6 void

However, I do not really like this approach. It really works harder: eval Why do you want to make global in runtime? On growing namespace and other ugly hiccups on the horizon. ..

c++ - Is it OK for an abstract base class have non-abstract methods? -

In an abstract base class (interface class) it usually has all its function summary. However, I have many such issues Where the member who calls the intangible methods of the interface works. I can apply them to a derivative-only-still intangible class, or I can implement methods in the form of non-abstract, non-virtual methods of the interface class.

Is any problem implemented according to the design design in the interface class?

For example

  class IFoo {Public: Is this a bad style, and if so, why?  
 Virtual ~ IFoo (); Virtual Double Calc (InputType p) const = 0; Virtual Double CalThat (Input Type P) const = 0; Double calcefructure (Inup type P) {calce it (P) / calcite (P); } Fixed BarType Bar (InputType p); }; Class MyFoo: Public IFoo {Public: // IFoo virtual double calc it (InputType p) const; // IFoo virtual double calceat (InputType p) const applies; };  

vs

  class IFoo {public: virtual ~ IFoo (); Virtual Double Calc (InputType p) const = 0; Virtual Double CalThat (Input Type P) const = 0; }; Class FooBase: Public IFoo {Public: Virtual ~ FooBase (); Double calcefructure (Inup type P) {calce it (P) / calcite (P); } Fixed BarType Bar (InputType p); }; Class MyFoo: Public Phobbs {Public: // IFoo Virtual Double Calc It (Input Type P) CONST; // IFoo virtual double calceat (InputType p) const applies; };  

if you call it an interface (i.e.) Which you seem to be using your naming convention "IFU"), then it should not be a pure interface (no implementation).

If this is only an abstract class, then the combination of pure virtual and implemented methods is absolutely reasonable.

Using a C++ dll in C# -

I am trying to consume a DLL written in the C # application from C ++. For C ++ DLL (Cyclone Physical Engine) I have 3 party source code and manually do not want to turn it off at C #.

In the C ++ project
I changed it to DLL output. I changed it to use the CLR flag I changed it to use multi-threaded debug DLL (/ MDD) because it is only one / compatible with CLR and also compiled.

In C # Project I added a reference to DLL. I am using a cyclone namespace.

At first there was nothing under the namespace. I think this is because in C ++ code, all classes were declared no access modifiers and default is private. Therefore, for this class "particle" I have changed this definition:

  public square particle {// ...}  

I have successfully changed Types of particle types from C # code However, the intellesense and object browser report declares a bunch of methods after having a struct (?) And there are no ways in it. C ++ code after "public": "Access modifiers so I do not know the problem What is it."

For example,

  public: zero integrated (actual duration);  

What am I doing wrong?

The particle class is not a managed class, so it is considered as a structure, it is ref To use keywords, it needs to be managed and collected for garbage collection. You also have to do it for every other class which gives context which can be a problem. The best solution I think, is to create a managed wrapper class which internally uses particle orbits. This wrapper class can then be referred to by .net.

Now, my question: is anyone doing this in C?

I am asking because we write embedded C and are considering implementing these methods without changing our programming language.

The signal to do this all the time in C is given in the reply given to Eder in your second link:

jquery - .ajax will not POST, but will GET with no problem -

I am trying to submit a form using jQuery's .jax () function. It seems that it should be very easy, but for some reason I can not find: "Post" to use the type to work correctly: "GET" is not a problem, but in fact " Post "does not post anything to accept my PHP PHP script. When I do a print_r ($ _ POST), I give an empty array that I have tried to use both input type and input "input" on the input of input but it does not seem to change anything

Edit for clarification
If I do this, print_r ($ _ GET) when I use Type: "GET", it prints all the correct data But if I change the ".jax" option to type: "POST" and print_r ($ _ POST) Try it, it shows an empty array, no content.

JS code:

 var dataString = 'reply_text =' + test + '& post_id =' + post_id; $ .ajax ({type: "post", url: "process.fp", data: datestring, cache: incorrect}); return false; 

Form Code:

 & lt; Form action = "" method = "post" & gt; & Lt; Textarea id = "textboxcontent" name = "reply_text" /> & Lt; Input type = "submit" name = "reply_submit" value = "submit comment" /> & Lt; / Form & gt; 

This can work better:

  var text = .. var post_id = ... $ .ajax ({type: 'post', url: 'process.php', data: {reply_text: text, post_id: post_id}});  

php - Memcache Vs. Memcached -

मुझे लगता है कि दोनों कार्यात्मक रूप से एक ही हैं, लेकिन उनके पास अलग-अलग लेखकों की है, और एक को दूसरे से उचित रूप से अधिक नाम दिया गया है।

activerecord - Rails has_many through singular association -

This is probably quite simple, but I am still unable to wrap my head around the problem.

I have 3 tables ... (better than that), but 3 in this scenario is this thing.

Placement Bookings and Ratings

Places have_many bookings

Each booking has a rating (because the user only rates one time) and related_ from (A) Place < / P>

Ratings are related (A) Booking

So even though there is only one rating in the booking, places have locations due to ratings through booking, there are many more booking places too.

But does it seem to work? All the rest seem to be.

There is a place_ID in the booking and booking_id in the ratings, and I have been successful through all the other organizations ... is not it just? any idea? Thanks

Apart from this: If I change the booking to a hotmee: Ratings do this ... but booking will be a rating for only one booking ... so this is not a good thing.

  Invalid source reflection macro: has_one has_many: ratings, via = & gt; : Bookings. Use: Source  

is to specify the reflection of the source: medium: By means of joining this model ; See the following railway tickets for details:

If possible, the best solution is to modify your relationships. > Has_one instead of rating a booking related_to one rating.

WPF ComboBox DropDown Placement -

I have a content control that is on the right side of a button, partitions and a combo box from left to the combo box dropdown. I want to line up with the left side of the control as opposed to the left side of the boxbox. Documents can not be found on relative placements, etc. Has anyone dealt with this? TIA

I did something before - I ended up with the combo box, taking part of the popup Control to control it and use it. Something like this ...

  class MyComboBox: combo box {public override zero OnApplyTemplate () {base.OnApplyTemplate (); Var popup = (popup) template.findname ("PART_Popup", this); Popup.placement = PlacementMode Custom; Popup.CustomPopupPlacementCallback = placePopup; } Private custom popup place [] place popup (size popup size, size target size, point offset) {var placements = new [] {new custom poppling ()}; Placements [0] Points = // status drop down here! Return placement; }}  

c++ - WM_ENTERSIZEMOVE / WM_EXITSIZEMOVE - when using menu, not always paired -

To prevent your application from changing window contents, when the user is moving around its window, I WM_ENTERSIZEMOVE / WM_EXITSIZEMOVE and I stop the application between messages. However, sometimes it happens that I get WM_ENTERSIZEMOVE but no WM_EXITSIZEMOVE not at all.

Click on the size

Instead of resizing the window, click on the window

WM_EXITSIZEMOVE not received notice.

While examining how it works, I have also tested the Microsoft DirectX sample and I have seen the same problem. Once you have followed the revised steps above, the sample application appears to be frozen (I have now tried to do it with a basic HLSL sample from March 200 6 SDK).

How is the application expected to react to this? Are there some other conditions that "transferring or shaping modal loop"

Should end?

I know that it's too late, but it still can help you - and there is a possibility to help other people to do it like I did.

It seems that in the case you mentioned, a WM_CAPTURECHANGED message is sent when the resizing is "Canceled". After extensive testing it seems that it is always sent before WM_EXITSIZEMOVE (or should!), And there is no other stage between WM_ENTERSIZEMOVE / WM_EXITSIZEMOVE.

The WM_CAPTURECHANGED message is also sent at several other times, so if you have sent a WM_ENTERSIZEMOVE message, you only need a response to it, but the following is not WM_EXITSIZEMOVE.

version control - Sharing git between different users -

I currently have a git setup where git is a user in my Linux box / home / git and / g / There are many git repositories in git: Git user has / usr / bin / git-shell if a user needs access to the repository, then I take his SSH DSA public and / home / git / it. Embed in ssh / authorized_keys and they will be able to work with the repository.

The problem is now that I need a second repository which needs to support a different group of users. I do not want to create a new account for each repository I created.

What is the best way to work with SSH? (The easiest way of all sharing techniques I have seen is that git supports)

The main advantages are:

• Only one SSH user (one can be damaged)
• Users identified by SSH keys
• Users on the fly using the GIT and repo were created

ole - Why would an ocx control not register properly? -

I am writing an app for which third party OSX control must be used in my INO setup script I include the line I am:

Source: C: \ aPath \ aControl.ocx; DestDir: {AP}; Flags: Restart Location Shared File Reserves

It seems that the control is registered, but the installed app tells me EOLSISR that the control is not registered while working in Win2000. Any ideas about what's going on here, or how to fix it?

Thank you, as always!

p.s I am working with admin level control I think that it is always necessary when an ActiveX control is registered. (Is this true?)

If the problem is only on Windows 2000 but in subsequent OS versions No missing dependencies, such as DLL or other OCX files that are not part of the standard Windows 2000 installation, may be due to. Versions of the Microsoft Sea Runtime Library come to mind. You should use free to track these types of problems, copy it to the problematic machine and use it to open the OCX file, then any missing library entry points or libraries will be shown.

You can also use the tool as a debugger to run your app. It will show a lot of information about loaded modules and similar stuff that can help solve the problem.

And yes, you need an administrator or a power user account to register an OCX.

visual studio - MSBuild AfterPublish Target -

I have to copy a special file with the published output of my web project, I to content and change the to copy the code to the output directory. to always copy it works fine except that it is below it in a sub folder As is left in the project.

I do not want to be buried in a sub-folder I want it to sit next to all the published outputs. I thought I could handle this problem by using the After Publish target instead.

Can someone show me how I can do this? I think I would need to know the path that someone was selected in the published dialog. The publishing feature is unfortunately buried inside deep within the visual studio, due to this you can do the expansion of the process, what you can do is very limited Because of this That's not as simple as a simple task you've told here, at least from your project file If you need to get better control of your web deployment then I can suggest that you have a look and / or I will add it to a web development project, which will prepare your web app for deployment with this custom file copy. , And then allow MSDeploy to do actual deployment for you.

java - what kind of data structure do i need to implement a hashlist for storing coordinates? -

I need to create a status manager class, tell me if the situation is available.

Tried to do this:

  Enter the code here  

Public Class Status Manager {

  hashtable current positions = new hashtable (); Zero occupied post (int x, int y) {this.currentPositionsput (new integer ("4"), new integer ("5"); This.currentPositionsput (new integer ("1"), new integer ("5"); This.currentPositionsput (new integer ("11"), new integer ("3"); This.currentPositionsput (new integer (" 42 "), the new integer (" 55 "); This.currentPositionsput (new integer (" 11 "), new integer (" 53 "); set key = this.currentPositions.keySet (); // Setter.teater = keys.Director (); System.out.println ("The map contains the following teams:"); while (keyIter.hasNext ()) {Object key = keyIter.next (); // Next key Obtain object value = this.currentPositions.get (key); // Get the value for the key System.out.println ("(" + key + "," + value + ");}} Public static zero main (string [] args) {New position manager (.) Captured The post (3, 3);}  

}

Of course this is just an exam, which I try to do I am getting it all the same again, it is used again, the problem is that if I can not duplicate the keys, then what kind of data structure should I use? New? Thanks in advance.

PostgreSQL In Memory Database -

The reason I want to run my PostgreSQL database server from memory is because on my new server, I have 24 There is memory of GB, and hardly any one is used.

I know that I can run this command to create a RAM disk:

  mdmfs -s 1024m md2 / mnt  

< P> And I theoretically store its data to PostgreSQL. But the problem with this is that if the server crashes or reboots, then the data will end.

Actually, I want to load the database all the time in memory so that it does not need to go to the hard disk drive to read every record, because I have tons of memory and since the memory is fast Compared to the hard disk drive,

Is there a way to do this when postgrescuclo is write to disk then do not lose any data in case I go to server Land? Or is there any way to cache all the data in memory?

I am now using streaming replication async This means that my master is running in all memory, using a traditional disc with a different slave example.

A machine restart involves stopping slave, copying postgrascill data back into RAMDisk, and then restarting the master and followed by slave. This is an interesting possibility which compares something like REDIS, but with the benefit of redundancy / hotstandi / backup / SKL / rich toolset etc.

64bit - Is there a 64-bit Ruby? -

It seems that people are compiling MRI Ruby (1.8.7) for 64-bit platforms. I have been searching and reading for a while, in fact without the answer I want, without it. What do I know if any of you actually used more than 4GB of memory in Ruby? Is Ruby really 64-bit if you compile it like this?

I have indicated that comments in source code have not been tested on 64-bit. For example, it says that "BigDiskm has not yet been compiled and tested on 64 bit integer systems."

It will also be interesting to know how to make other implementations in Ruby's 64-bits.

MRI (both 1.8.x and 1.9.x lines) can be compiled as 64 bits is. For example, Snow Leopard has been compiled as bundle with 1.8.7 as 64 bit. This activity can be viewed in the monitor, or by asking irb , for example 42.size . If you have been compiled in 64 bit, 4 (byte) otherwise, you will get 8 (bytes).

Ruby will be able to use more than 4g of mem. For example:

  $ irb> & Gt; N = (1 <29) & lt; + 8 = & gt; 536870 920 & gt; & Gt; X = Array.New (n, 42); X.size = & gt; 536870921 # bigger than one because it contains 0 to n inclusive elements  

If you do not exceed 4G or RAM then getting the last line will take some time because the OS will swap too much, but Even works with 4 GB on my machine. The size of the virtual RAM for this process was 4.02G.

I updated the comment to the large DCMML file which was outdated (from March 2003 ...)

javascript - How do I give an HTML canvas the keyboard focus using jquery? -

I am implementing a game using javascript, jquery, and canvas tags. How can I prevent the browser from processing keyboard shortcuts when the canvas tags have a focus? I have tried event.stopPropagation () and it has no effect.

I can select keyboard events However, when the user presses the space bar, the web page scrolls down in Firefox. The same problem is with the arrow keys

The basic problem is that by default the browser canvas is not "focusable" Does. Setting up tabindex on the canvas is best done:

  $ ("# canvas") // Keep the tab index to ensure the canvas keeps focusing .attr ("Tabindex", "0") // Keep the mouse override to prevent default browser controls from appearing. Footprint (function) ($ (this). Focus (); return returned;}) .keyword (function () {/ * ... game logic ... * / incorrect return;});  

If for any reason you can not set to tabindex , you can make the canvas "focusable" by setting up contentEditable Can add edit material to help ensure that the canvas retains the focus $ ("# canvas"). Ether ("content editable", "true") $ ("# canvas") [0] .contentEditable = true;

This is basically the solution I came across, but in my opinion it is a little less than the tabindex option.

One more thing to consider is that the browsers outline the content editable elements along the border. This can be closed to some users. Fortunately, you can get rid of this bit of CSS:

  #canvas {outline: none; }  

I tested both solutions in Chrome 3/4/5 and Firefox 3.0 / 3.5 / 3.6 on Windows XP, Mac OSX and Linux. Here's an example:

dojo - Overriding dijit validator function and using regExp attribute -

I'm new to dojo and actually can use some help in the following 2 field validation examples.

In the following example of a dijit.form.ValidationTextBox area, the use of regExp seems to override the validator property. (Ie the area no longer follows regExp rule). How do i do it

& lt; Input dojoType = "dijit.form.ValidationTextBox"
type = "password"
name = "password2"
id = "password2"
maxLength = "50"
trim = "true"
regExp = "[\ w] +" required = "true"
validator = "return.value == dijit.byId ('password'). Value"
invalidMessage = "Confirmation password matching password Should eat "/>

I have another similar example where one field is the value of another, but I do not have the correct syntax.

& lt; Input dojoType = "dijit.form.ValidationTextBox" type = "text"
name = "homephone" style = "width: 20%"
maxelag = "10"
trim = "true"
essential = "false"
regExp = "[\ D] {10}"
validator = "return (dijit.byId ('preferredContactMethod') value ==" Home ") & amp; amp; amp;; (this.value! = Null)"
invalidMessage = "Home phone is required (i.e. 9 1988887777)" />

correct; The default implementation of Dijit.form.ValidationTextBox.prototype.validator () is to match this. Check with ARXXPP, as well as against other such constraints. Take a look at the source to see how it is done. If you override it, then you have your own to provide the implementation. You can choose to assign your implementation prototype method and you can also override the result with 'and' your own tests, Wide, I think.

ASP.NET get windows username outside of page -

I have an existing ASP.NET reporting application that is using Windows authentication. The report is a very different class of generation code and has a core error logger that I have not written, error logger I believe that Windows was built for applications because it uses WindowsIdentity.GetCurrent (). In the case of ASP.net I believe that it will return the account running the ASPNNet page on the server.

I believe the user Using Identity. The page on the name will be the way to do this correctly but this is not available within the Report Generation Classes on the page, is it a way to get the missing error logger class as an additional parameter

There are hundreds of reports sections, so I have to be afraid that each parameter has to be added.

If you can use cloning in your web.config:

  .... & lt; Authentication mode = "windows" /> & Lt; Identification impersonation = "true" />  

Your report sections will find the right user.

If your reporting classes system Can refer to the web assembly and you are willing to modify the code, you can also:

  httpctx Present. User. Identity .name  

But make sure the caller comes from an ASP.NET request or throw it a null.

terminology - What is Cloud computing? -

Does cloud computing work, can anyone explain in plain words? I have read, but it is still not certain how I understand how the cloud actually works.

Marketing period?

Basically all the needs of your program are organized "elsewhere" on the Internet. You interact with them through a defined service agreement; Depending on the SOAP, REST, POX or whatever and what happens after the service provider.

If, for example, you want to store files, you can choose to use Amazon's S3 Cloud System, you have no idea how your information is stored or how the service Is provided. . You join the service and upload your files; You do not know where or where the files are stored, that's the only place for the entry point for that service.

If you have any application then it can also be run in the cloud, suppose it is appropriate. For example, Live Mesh is a virtual machine that can code against you and run your software locally and in the cloud, so your user goes to the URI only and finds your program, you do not care that it is anywhere Not available on the cloud.
