asp.net - Using IIS 7 Redirect Module or coding your own -

What is the difference between using the IIS redirection module to redirect. Just play with your own coding and response kintext? It does not matter to me, they both do the same thing and it is very easy to use the redirect module in IIS because it is relatively redirected anyway! As this code is doing, it is a global. AS says:

App. response. Status = "301 move permanently"; App response. Adhider ("location", new location);

Am I not right? You can do the same thing in 2 different ways! IIS or code! Use IIS only to web.config in your app:

  & lt; HttpRedirect enabled = "wrong" destination = "http://www.domainToRedirectTo.com/" exact destination = "false" httpResponseStatus = "permanent" />  

Good and simple! Accurate determination is false, so it will be redirected to a destination based on a relative basis.

I have to listen to arguments against using one side versus one side because I do not see any argument that would benefit in any way. Both satisfy the same goal.

The way you put it, there is no difference. A coded version allows you to respond to input on the runtime and to redirect people to different pages - use this code for a login.aspx page Can be unsuccessful -page.aspx or login- succesfull-page.aspx . If it's just hard-coded no difference

Remember that the redirects do not mean the sign of permanent rehabilitation of the URL only. . You may want to redirect people to a temporary message (redirect code 307) - for example, if you are working for Apple and Steve Jobs is giving a key word - that is, "Steve Jobs has a redirection to the store. Is giving the main word and we are updating the store "page in this example to give a switch a blow and update your entire web-form to the configuration files of all the IIS servers Instead of choosing the change through runtime logic. Each redirection has its own purpose.

python - Is RLock a sensible default over Lock? -

Threading module in Python provides two types of locks: a common lock and a recantent lock I think if I lock it Should I always like RLock on lock; Mainly to prevent deadlock situations.

In addition, I get two points, when lock on an RLock is preferred:

• There is a more complex internal structure in RLock and therefore poor performance Could.
• Due to some reason, I want to restart a thread through lock.

Is my argument correct? Can you tell other aspects?

two points:

• Officially Python version (2.4, 2.5 to 3.1) is much slower than a lock lock, because locks in C and RLox in Python apply (this will change to 3.2)
• A < / Li>

Bottom line, I can release it from any thread (not necessarily the thread that receives it), while an RLock should be released from the same thread, D only a Suggests using Arelk if it coincides with the words that you are looking for, otherwise default glued locks.

asp.net - Running a query in Page Load a bad idea? -

I am running an asp.net application in which I added a [insert] global / page_load query / update query. Therefore, every time the user hits any page on the site, he updates the database with his activity (session ID, time, hit on the page). I have not implemented it yet, but this is the only suggestion that I take care of how many people are currently on my site.

Is it going to kill my database and / or IIS for a long time? We believe that the site is average between 30,000 and 50,000 users at a time. I can not lock on top of a database hit continuously with every single page hit for my site every single user. I am worried what will happen, though this is the first time that I have tried a solution in this way, so I can become very crazy.

Disable it.

Create a DLL that handles the update, and the page load is a fire and forgets with the parameter.

javascript - jQuery - remove list items based off of time -

I currently have a page in which there is an anonymous list that is initially populated by my DB inquiry into the list, Each list item has a time stamp and text, if Javascript and AJAX are to be used, then this page updates dynamically without any inventory every 10 seconds, if the new data has arrived.

What is the easiest and most effective way to remove items from the list from the list, more than 24 hours old?

My tendency is to do the following:

1. In the js file, load all list items in an array in an unreserved list
2. To get data during the data, if the data comes back, then add those objects to the array also
3. Each time the matching () function is called, it also removes a distant data () function Which removes all items that are older than 24 hours

In addition, I have a javascript Attempted to remove the correct way of adding list items to the script array is a code here that I am trying to add to all the list items in an array:

  var list = new array ( ); $ (".listname") Each (function (i) {list.push ($ (this));});  

To delete list items from the array, I expect to use it:

  list.pop (); Why do not array first (oldest first), then use   

? This will remove the first item in the array, as described.

parsing - Lexer written in Javascript? -

I have a project where the user needs to define a set of instructions for the UI that is completely javascript Has been written in I have the ability to parse a string of instructions and then have to translate them into instructions. Is there a library to parse 100% javascript? Or a generator that will be generated in javascript? Thanks!

Something like that, maybe?

The first available parser development system for JS / CC is - Dividives It has been developed, both for the purpose of producing productive compiler development system and how to normally do the bottom-up parsing Pars table generation is done, with the intention of creating an easy-to-use academic environment for those interested in it.

Both platform-independent software associations: a regular expression-based generator from the input character stream to a personal token and a parser generator , parse tables Calculating the formation of a stand-alone, working parser for a given specification and free grammar referenced to JS / CC is defined in an individual meta language, and the individual semantic code is defined as To Milit can be evaluated on the cut rule.

JS / CC is fully written in ECMAScript , it can be executed in many different ways: platform-independent, browser-based JavaScript Embedded on the website, as a Windows Script host application, as a compiled JScript.NET executable, interpreted by Mozilla / Rhino or Mozilla / Spiderman, or V8 shell script on Windows, * n Bus, Linux and Mac OSX. However, for productive execution, it is recommended to use command-line versions. This version is capable of collecting a full compiler from the JS / CC parser specification, which is later stored in the .js Javascript source file.

flex - How to make a property bindable? -

I have a class like this. The property is based on "ipboard" filed "ecboardid", I have found that when Accced changes, UI controls do not see that "ipag" has also changed. So, how to make this property binding? PUBLIC class encoder EventDispatcher {public worker ecboardid: String; / * -......................................... Methods ..... ..................................... * / public function copyFrom (newEncoder: encoder): zero { Ecboardid = newEncoder.ecboardid; This.dispatchEvent (new event ('isPagChanged')); } [Bindabal (event = "ipt switch")] Public function found ipag (): boolean {if (this.aconbird! = Null) {if (this .onlyboardid.search ('xxx')! = -1) {return False; } Back true; } Other {return false; }}}

Edit:

If I change the property to a static job,

 < Code> [bindable] public class encoder event dispatcher (public worker excibid): string; / * -......................................... Methods ..... ..................................... * / public function copyFrom (newEncoder: encoder): zero { Ecboardid = newEncoder.ecboardid; This.dispatchEvent (new event ('isPagChanged')); } Public static function isPag (string excreb): boolean {if (ecboardid! = Null) {if (ecboardid.search ('xxx') = -1) {return false; } Back true; } Other {return false; }}}  

Tie this way:

  visible = {encoder.ispag (encoder.acbddid)}  

works? Will the encoder see a change in a boobed?

c++ - Is there an occassion where using catch all clause : catch (...) is justified? -

Every time I have caught all the statements:

  try {// some code } Hold (...) {}  

In this always has been misused

Arguments against using cache All sections Are clear This will include anything that contains OS exceptions such as Access violation, since the exception handler can not know who it is working with, in most cases the exception is ambiguous log message or some incompatible message box Will appear in the form.

then hold (...) seems natural evil

but it has still been implemented in C ++ and other languages ​​(Java, C #) applies the same technique. So in some cases it is fair use?

The argument against using cache is clear all sections, these OS exceptions such as access The violation will catch anything because the exception handler can not know what the behavior is with it, in most cases the exception will appear as a fuzzy log message or some unorganized message box.

And if those same exceptions aren

hold (...) presenting at least my self message box (And starts customizing) logging, saving crash dumps, etc. ).

I think the Destructors have proper use of hold (...). I can not throw devastators - well, I mean, they can throw, but if a district without any progress Because of the exception of the thrown during the pile, the program ends, so they should not allow the exceptions to be avoided. It is generally better that instead of ending the program, the exceptions continue to be uninterrupted first.

Another situation is in a worker thread that can work arbitrarily; Normally you do not want an unexpected accident if the worker throws an exception. The worker provides the opportunity to clamp (...) semi-cleanliness and closure in the thread.

html - Do IE Conditional Comments slow down page load? -

I am creating "CSS hacks" "conditional comments" vs "recent logic" This question is out of the stack overflow community is.

  & lt ;! - [if IE] & gt; & Lt; Link type = "text / css" rel = "stylesheet" href = "yi-specific.css" /> & Lt; [Endif] - & gt;  

By using IE conditional comments the main argument it appears that you are adding additional HTTP requests to each page, thus slowing down your page's performance

Except for the reason of the maintenance of several stylesheets versus maintenance of stylesheets, I am able to find any real-world metrics I is not though it is a legitimate in itself Is there a discussion), is anyone here? What is the purpose of recession using conditional observations that you have been able to, or any other data, can be able to point me in the direction?

This conditional comment is not about actually , this conditional compilation Is like

An IE browser should appear on your page as

  and   

(with a small bit of additional processing to evaluate the status of the comment)

Any non-IE browser will simply see a comment.

Only potential performance effect is that the IE browser will need to evaluate conditional comment status (which is going to be negligible), and then going to include another CSS file. Of course other Browsers just see normal files and ignore comments completely.

The question is that the IEEE 5Kb standard-) 2Kb "hacks" file, and everyone else is receiving just 5Kb files; Versus a 7Kb file showing it with blackjack CSS. Depending on the various factors including the speed and latency of the network, the size of the file, the number of resources used on the page, it can have a noticeable effect on the IE case (this can certainly be faster than non- For IE user agents).

With all the display questions, you will have the effect of your code to see the profile in your environment - but in general guidelines I expect that the effect for IE, Increasing a small display for all other browsers, as well as feeling fuzzy, be able to write "appropriate" CSS in your actual file and then fix IE separately.

c# - Emulating ShowDialog functionality -

मैं एक आवेदन (c # + wpf) लिख रहा हूँ जहां सभी मोडल शैली संवाद को UserControl मुख्य विंडो को कवर करने वाले पारभासी ग्रिड के शीर्ष पर। इसका मतलब है कि केवल एक विंडो है और यह सभी फर्म अनुप्रयोगों का लग रहा है और महसूस करता है।

जैसा कि आप देख सकते हैं, न केवल निष्पादन का प्रवाह वास्तव में उलटा है, लेकिन क्लासिक। NET संस्करण की तुलना में इसकी बहुत ही सीखी बात है:

javascript - String Dot String (Mail without Domain) RegEx -

Really stuck on this simple regex. It needs to validate the string, which will be a match without "@ domain.xxx".

It must fulfill the following rules:

• No string
• A string (letter only) should end.
• The two strings must be separated from a dot.
• There should not be any numbers or symbols in the full string.

I was trying something like ... / ^ [az] + $ / ^ [.] + $ / [Az] + $ / I ... but not success

  / ^ [azza-z] + \. [AZA-Z] + $ /  

ASCII will work for letters.

Try International Letter (äá etc) if you also want to allow

  / ^ [^ \ w \ d _] + \. [^ \ W \ d _] + $ /  

[^ \ w \ d _] means any letter which is a non-alphanumeric character Not a number, and not an underscore ".

Best plugin development practices to avoid polluting jQuery namespace? -

I have created a jQuery plugin that allows the user to interact with a tree (creating, updating, deleting the node) gives. There are at least one dozen ways to interact with the tree. Ideally, I do not want to pollute the jQuery namespace with all these tree-specific methods because I now offer an extra opportunity for a namespace collision in every way. I just want a method to activate the plugin and so I'm looking at the refactor.

  $ ('ol # tree'). Trees (options) // Just a single jQuery method invoice ('Li # Item 6') // ... However, we have this subsidiary method $ ('ol # tree'). Adendod (node) // ... and this is a $ ('li # item2') extension branch () // ... and this one, etc.  

What are some practices to highlight an active DOM element and an interface for its sub-do not contaminate the Japanese namespace?

I have worked to save the returning jQuery object while creating a tree.

  var tree = $ ('ol # tree') tree () .;  

The object of this tree will be expanded to include methods only. Unfortunately, the tree is being manipulated regularly, it is the risk of having the position of that object Sends out the synchronization with the status of parent dom entry and its sub-elements. I'm not sure that trying to maintain the state in that object is worth it, since there will always be a current situation in the DOM.

I have considered using a namespace (via John Raisig):

How do you control this problem? Can you talk to some existing plugins that address this problem whose code I could learn?

Small and crisp name! Not boring trees , but for example Niketry (Hey, this is just an idea)! Put the interface in the name. Like this:

$ ("ol # tree"). Nicetree.appendNode (node); $ ("Ol # tree") nicetree.item ("Lee # ITEM2") expandBranch () ..

Another idea is this object that comes back as your offer, but do not update this object. This object is only a reference to the real object or dome, it adds a layer of indirection and it can not be acceptable for you.

I would like both solutions as a plugin user, but I like the first one.

user interface - What is the rationale behind UI namespace in Qt? -

UI file creates 2 squares with the same definition in the process of creating user interface code from QT.

  class UI_CustomeUIClassFromUIfile {// code is generated from UI file via UI} Namespace Yuri {class CustomeUIClassFromUIFile public: UI_CustomeUIClassFromUIFile {}; } Using namespace UI;  

What is the reason for having 2 squares in the UI namespace and without another one without namspace? Is it for the compiler to support, in which there is no support for namespace, there is a macro like QTNAMESPACE.

The macro is QT_BEGIN_NAMESPACE, which is used if you compile QT to stay inside someone Are there.

For 2 sections, I think you answered it yourself You can use either Ui_XXX or Ui :: XXX . I always prefer the Ui :: method, but for every one.

So I think there is no real answer to me as a logic other than choosing a programmer.

Quickest way to insert into SQLite using C API? -

I want to include a lot (let's say millions) as soon as possible in the database. Since I'm calling from C, I thought there might be a shortcut to do this in the API. I can not help, but I think that the string from the data is created and the string is written back, all in one call, it is least efficient.

Is there no way to insert data into SQL strings? Ready statement is the only way?

I am looking for the se-specific methods of inserting data in the most efficient way, not general database tips

Start a transaction in the code, and a committed commit will be in all inserted memory before being written to disk. (How much memory is available to you, and depending on how much data you enter it may have to be trudged) This is going to boost you to the biggest exposure you will see.

Otherwise, if one is included in the same table, to prevent the text processing overhead, after each one is inserted, then reboot the one line in one of your data at the same time. However, compared to transactions, this would be relatively minor, most of the time your inserted disk will be written in ...

C# - Sorting using Extension Method -

  Public Enum Comparison Option {P> How to go sorting using lambda expression What is it?  
  Public Stable List & lt; Person & gt; Sort People (this list & lt; person & gt; lst, compare option opt1, sort order order) {lst.Sort ((p, op1, op2) => {lambda expression can be implemented here} ); }  
 

It looks like you call the sort method on list & lt Trying to; T & gt; which is a comparison & lt; T & gt; Represents. This will require little work because you have to first define a consistent comparison function

The first step is to select comparison option value

  private Stable comparison & lt; Person & gt; To write a comparison function on the basis of. Create (Compare Optimization Opt) {switch (opt) {Case comparison option. Byfirst debit: (x, y) => X.FirstName.CompareTo (y.FirstName); Compare matter option. Child name: (x, y) => X.LastName.CompareTo (y.LastName); Compare the caseFeatures Bilassari: (x, y) = & gt; X Salary - Y. Salari; Default: throw a new exception (); }}  

By default this task will be sorted in ascending order. If you want it to fall, then just deny the price. So now the sorting people can be written by following

  public static list & lt; Person & gt; Sort People (this list & lt; person & gt; list, compare option opt1, sort order order)) Original Origin = Create (opt 1); Var comp = Original; If (ord == SortOrder.Descending) {comp = (x, y) = & gt; - (Original (X, Y)); } List.Sort (COMP); }        Edit

javascript - How do I pass the image object into the onclick function being assigned to it? -

Sorry, if that question is confusing, then I'm learning JavaScript myself, I'm dynamically generating image thumbnails and When the user clicks on the thumbnail, I want to enlarge the image. My code looks like this for creating image code and assigning onclick function ...

var imageTag = "& lt; img onclick = \" enlargeImage () \ "class = \" Thumbs \ "Src = \" "+ photoURL +" \ "/" /> "; Document.getElementById ("image-thumbnail"). InnerHTML = imageTag;

With the code above, my thumbnail is displayed and when the user clicks on it, the enlargeImage () function is called . My question is, how can I use an image object clicked inside the enlargeImage () function? Tried to reach the this object inside the function, pointing to that image that was clicked, but this was referring to the whole page, not the The image was clicked. I want to be able to change the src attribute, as well as changing the style attributes of the image thumbnails. I should also note that there will be many images after all, so I need this dynamic behavior is.

Thank you very much for your help!

There are some ways to do this: The simplest way is to change the AA parameter to enlargeImage () Add it to the function and when you call it, pass it this reference.

  var ImageTag = "& lt; img onclick = \" big size (this) \ "square = \" thumb \ "src = \" "+ photoURL +" \ "/> ; ";  

Then in the function ...

  function big size image (IMG) {alert (IMGSRC); }  

How to make the browser back button work for a Flash-based Website? -

Can the browser back on some previous frames when clicking the back button in the browser? Similarly, can the fresh button be used to refresh the same frame and should not go back to the starting frame again?

It depends on how you make it. First of all, you have to import something called SWFAddress. To use SWFAddress, you need to make sure that you are embedding your flash using SWFObject, not just the object / ambit tag.

SWFAddress lets you add anchor tags to your URLs. This allows you to change the URL in such a way that the browser can understand without refreshing the page. For example, if my app is on www.mypage.com/flash and I set up SWFAddress I can set it so that when I press the button to go to the page, the following happens:

< Ol>

SWFAddress varies my URL to www.mypage.com/flash.html # Page 2

Javascript SWFAddress files notice this change and notify the flash.

Flash says, "Oh, look, the URL is changing and someone is paying me" Page 2 "- What do I want to do with that?

You can set a switch statement that will allow Flash to respond to these events in an intelligent, predictive manner - for example, you can say "if url changes in 'page2', Goto and sitop (2)" If you are running things, then it is the same.

I do not necessarily have to Frames will be doing, however - what you really want is the functions of controlling the behavior of the functions. Instead of pasting all of you, page 2 content in frame 2, you create the function goto page (2) And put their logic there.

As far as one frame is to refresh, then it depends on how you code it - but if someone in the browser refreshes it The browser window will always refresh. With SWFA Picture, however, if you have set it correctly, it will always take you to the destination that you have linked to anchor tag.

  Get long personal property (last string value) {byte [] bytes = value.getBytes (); Int length = bytes. Lamps; Long multiplier = 1 l; If (bytes.exe; gt; 0) {if (bytes [0]> = (four) 0xB0 and bytes [0]  gt; = (four) 0xB0 and bytes [length - 1] & lt; = (four) 0xB9) {bytes [length - 1] & amp; = 0x7F; // bit pattern: 01111111 multiplier = -1; } Second multiplier = 1; } Second multiplier = 1; Return long. Arrays.toString (bytes) * Multiplier; }  

Am I correct?

asp classic - Debugging ASP Stored Procedure Calls -

मैं एक SQL Server 2005 संग्रहीत कार्यविधि को कॉल करने के लिए निम्न कोड ब्लॉक का उपयोग कर रहा हूं। समस्या यह है कि कॉल अंततः असफल हो जायेगा। मैं असफलता के मामले के बारे में अधिक क्रियाशील जानकारी कैसे प्राप्त कर सकता / सकती हूं? मैंने असफल इनपुट के साथ एसपी का परीक्षण किया है और मुझे कोई समस्या नहीं मिली है। यह एएसपी पक्ष पर एक त्रुटि को इंगित करता है।

  सेट rsOrderItems = Server.CreateObject ("ADODB.Recordset") rsOrderItems.ActiveConnection = MM_SkateSeason_Connect rsOrderItems.CursorType = 0 rsOrderItems.CursorLocation = 2 RsOrderItems.LockType = 1 rsOrderItems.Source = "{dbo.upOrder_InsertNew ('' और amp; MM_OrderString & amp;" ')} "त्रुटि पर फिर से फिर से शुरू करें rsOrderItems.Open अगर (rsOrderItems.State) और फिर असफलता InsertOrder =" आदेश विफल 2 "अंत यदि

php - Zend_Paginator; is it optimized? -

I'm going to use the Zend_Paginator class in my project. I found examples of class on the Internet, one of them is

  $ sql = 'Select' from 'table_name'; $ Result = $ db- & gt; Get all ($ sql); $ Page = $ this- & gt; _getParam ('pages', 1); $ Paginator = Zend_Paginator :: Factory ($ results); $ Paginator-> SetItemCountPerPage (10)); $ Paginator-> SetCurrentPageNumber ($ page); $ This- & gt; View-> Paginator = $ paginator;  

On the first line, it will actually pick all the rows from table_name what if I have 50000 lines? It would be very disabled.

Is there any other way to use Zend Pageant?

Regarding this problem, you may be interested in this section of the manual: ( Quotation, Zor Khan) :

... database adapters require more detailed explanation
Contrary to popular belief, to calculate these adapters database Do not get all records from Instead, the adapter adds the original query to create the corresponding COUNT query
legs Greater then execute COUNT query to get the number of rows.

This requires additional rounds of databases to travel, but bring the whole result set and multiply it by using count () It's fast.
Especially with large collection of data

(There is more to read on that page - and there is an example that should give you more information)

The idea is that you will not bring all the data yourself , but you should use the Zend_Paginator adapter to access your data.

This adapter will be specific to " data that is brought through SQL query ", and how it will be found directly on the database side - which means that only the required Which is being brought, and not initially all the data like you.

asp.net - Crystal Report Viewer Accuracy -

I have several crystal reports that I am displaying in the viewer in an asp.net web page. These reports have been very advanced with tables and charts on them. What we have seen is that these lines take on the self, often outside the pixels in the preview, or from the bottom of the page Running is not a problem when you run reports in the Crystal Designer app, only web preview is anyone seen or solved in the past?
