iphone - Memory Management of Interface Builder Outlets -

I use @property (nonatomic, retain) for my IBOutlets for an iPhone application I am doing. However, I'm not sure that to ensure that I am organizing the memory with them, IBOutlets have been installed in all interface builders, so I never call alloc manually I am here. This means that I am not sure where and when to notify them or to set them to point to zero .

What are the best practices for ensuring that no memory is leaked at once? If you use @protectives for your iBotletlet and make connections in IB, then your controller is

When you are done with them,

In each case, you should be setting your property self.propertyname = zero in your viewDidUnload method And again in each view controller's dealloc .

It's fairly straight forward, the IB manages everything.

.net - Detecting Process Creation -

Let me have a third-party NET application process will be detected. My goal is to inject a plugin DLL to increase the functionality of this app. I like to inject it as soon as possible so I can catch the initial events of the application. Is there any way to find out that when this process is made and the main is injected before DLL?

The common solution is to replace the target address image with a stub, which launches the original image under controlled parameters Does.

There are other ways, such as, but they are meant for debugging for normal operation.

html - Validating Form Data and Displaying Graphics with JavaScript -

I have not really used JavaScript before, but I am trying to validate the form elements because they are filled Are there. I have an X and a check mark that I am trying to show next to the field to display whether it is valid or not. I know that this is partly correct because I can use a warning, but I'm not sure how to change the fields of graphics.

Javascript:

  function validate_field (field) {var value = document.newAccount.fname; If (value == zero; value == "") {document.fnameX.visibility = visible; Document.fnameOK.viewability = Hidden; // warning ("unsuccessful"); return false; } Other {document.fnameX.visibility = hidden; Document.fnameOK.visibility = visible; // warning ("true"); Back true; }}  

Some HTML:

  & lt; Form action = "xxxxx" method = "post" name = "newAccount" & gt; & Lt; Table width = "78%" range = "0" align = "center" & gt; & Lt; TR & gt; & Lt; Td colspan = "2" & gt; & Lt; Strong & gt; Personal info: & lt; / Strong> & Lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; Td width = "24%" & gt; & Lt; Div align = "right" & gt; First name: & lt; / Div & gt; & Lt; / Td> & Lt; TD width = "76%" & gt; & Lt; Input type = "text" onchange = "return validate_field (this)" onfocus = "return validate_field (this)" name = "fname" tabindex = "1" size = "50" /> & Lt; Img name = "fnameX" src = "redx.jpg" style = "visibility: hidden" alt = "x" width = "18" height = "18" /> gt; & Lt; Img name = "fnameOK" src = "Checkmark.jpg" style = "visibility: hidden" alt = "ok" width = "18" height = "18" /> gt; & Lt; / Td> & Lt; / TR & gt; & Lt; TR & gt; & Lt; Td> & Lt; Div align = "true" & gt; Last name: & lt; / Div & gt; & Lt; / Td> & Lt; Td> & Lt; Input type = "text" name = "lname" tabindex = "2" size = "50" /> gt; & Lt; / Td> & Lt; / TR & gt; & Lt; / Table & gt; & Lt; / Form & gt;  

It is possible to use CSS classes for something like that.

. Valid (padding-right: 15px / *) or the width of your graphic * / background: url ('checkmark.jpg') center is not correct-repeat; / * Remember that the URL is relative to the stylesheet. /}. Valid (padding-right: 15px background: url ('redx.jpg') center is not correct-repeat;}

Then your valid work is done:

  function validate_field (field) {var value = field.value; if (value == faucet} value == "") {field.parentNode.className = 'invalid'; description is false;} other {field. ParentNode.className = 'valid'; return true; Keep in mind the entry, keep in mind that unless you are using a warning or using the accessibility facility, Users are going hard times with your form.  
  Edit:   
 An example of your code where I change the background of the form input Color of the original table cell.  
  Edit:   
 And this is an example where I got rid of those layout tables and gave them a  Fieldet with , and modified javascript in a bit. If you are not familiar with jsbin , You can add  / edit  in the url to view / modify the code. 
 

ierrorhandler - Implement 'Ping' functionality using Message Inspector causes WCF runtime to throw NullReferenceException -

I am using WCF to implement a web service. This web service requires a 'ping' feature in the form of a health monitor for each service. This functionality is implemented using the IDispatchMessageInspector and is configured for each endpoint of a service. This is due to the need to have as close to the actual service code as possible for 'Ping'. Also, I did not want to pair it in the code of each service implementation and the IDIPF Message Inspector looks a good fit.

This service uses the request-answer MEP. Each request message contains an element that specifies which resource is needed. Then the message will use to determine how this message will process the data. The use of the same element is used to define a 'message' as the 'heartbeat' probe.

The 'Ping' message inspector will later post the request message in the process of the next, and if it determines that the request is a 'heart beat', it will then produce the correct reaction and the first syndrip ( ) The method is obtained through a correlation object since the latter is afterReceiveRequest (). According to the reference, AfterReceiveRequest () is set to clear the message parameter, then to stop the message from being processed by the service implementation code.

The technique to set the request message was found to be zero in a web site or blog which I can not remember nor find the URL. This technique works very well on itself and I can stop the service implementation code if it is requested to 'heartbeat'.

Unfortunately, to send empty messages in the Message Inspector to the WCF Runtime always throw a NullReferenceException stack trace, I still have to run the Runtime message object (which go through the 'Ping' message inspector Will be empty after) send to the sender and when the sender wants to delete an empty message object, NullReferenceException happens.

However, my system also applies IErrorHandler to capture and log any unrestricted exception in the service. This means that requests for every successful 'heartbeat' will generate the log entry for the tone reference option and 'heartbeats' can occur as often as each minute.

Question:

What can I do to stop the entry of 'useless' when the 'empty space' was dropped, the extension was thrown when 'Ping' service execution code canceled Prevents the request from being set.

Many thanks in advance.

hg

Not the most attractive solution but the potential solution (which I have not tested ), But where do you find your ping call in the inspector code, can not you throw your own custom exception type i.e. PingRequest Expression, and when it returns to the client, can handle it? Do you avoid killing the WCF runtime code, thus avoiding logging of obsolete exceptions.

Otherwise, you can try to use the base service inherited by all of your services (on the other side of the WCF Runtime Code), which ping requests in the manufacturer before hitting the actual service code And handles. / P>

php - Adding a block of XML as child of a SimpleXMLElement object -

I have this simple assemble object which is similar to the XML setup with the following ...

  $ Xml = & lt; & Lt; & Lt; EoX & lt; Books & gt; & Lt; Book & gt; & Lt; Name & gt; ABCD & lt; / Name & gt; & Lt; / Book & gt; & Lt; / Books & gt; EOX; $ Sx = new simple assemment ($ xml);  

Now I have a name class that includes information. I can also exclude the book's information about the same classes about each book. In the above (nested block) XML format. Example,

  $ book = New Book ('EFGH'); $ Book & gt; GenXML (); ... will generate & lt; Book & gt; & Lt; Name & gt; EFGH & lt; / Name & gt; & Lt; / Book & gt;  

Now I am trying to figure out a way by which I can use this generated XML block and attach it as a child of that type so that it is now Looks ... for example

  // non-existent member method for illustration purposes only $ Sx-> Adxmlbid ($ book-> gnxml ()); ... XML tree now looks like this: & lt; Books & gt; & Lt; Book & gt; & Lt; Name & gt; ABCD & lt; / Name & gt; & Lt; / Book & gt; & Lt; Book & gt; & Lt; Name & gt; EFGH & lt; / Name & gt; & Lt; / Book & gt; & Lt; / Books & gt;  

I have read on SimpleXMlelement, from the document, addChild () will not be done for you because it does not support XML data as a tag value is.

Two solutions First, you can do it with the help of libxml / DOMDocument / SimpleXML: Importing the code is $ sx , create a DOMDocumentFragment and use:

$ doc = dom_import_simplexml ($ sx) - & gt; Master document; $ Piece = $ doc- & gt; CreateDocumentFragment (); $ Fragment- & gt; AppendXML ($ book & gt; genXML ()); $ Doctor & gt; DocumentElement-> AppendChild ($ piece); // Your original $ sx is now already modified

You can also extend from SimpleXMlelement and add a method that is providing it. Using this specific object, you can easily allow the following to be created:

  $ sx = new MySimpleXMLElement ($ xml); $ Sx-> AddXML ($ book & gt; genXML ());  

Another solution is to use an XML library which has already created this feature such as SimpleDOM . You grab and you use insertXML (), which acts as an ADXMLBID () method that you were describing.

  Include 'SimpleDOM.php'; $ Books = simplest_load_string ('Books & gt; & lt; Book & gt; & lt; Names & gt; ABCD & lt; / name & gt; & lt; / book & gt; & lt; / books & Gt; '); $ Books- & gt; InsertXML (' Book & gt; & lt; name & gt; EFGH & lt; / name & gt; & lt; / book & gt;');

c++ - opencv multi channel element access -

I am trying to figure out how to use OpenCV's new c ++ interface.

For elements of multi-channel matrix, for example:

  matte (size (3, 3), cv_32 fc 2); For (int i = 0; i  

What is the easiest way to do this? Some cvSet2D like the old interface - What is the most effective way? Similar to using direct pointers in the old interface.

Thanks

  typed fip elem_ {float F1; Float F2; } Elem; Elem data [9] = {0.0f}; Cvmat mat = cvmt (3, 3, cv_32 fc2, data); Float F1 = CV_AMEEDMEM (Matt, AMM, Row, Call). F1; Float F2 = CV_AMEEDMEM (Matt, AMM, Row, Call). F2; CV_MAT_ELEM (mat, AMM, line, cola). F1 = 1212.0f; CV_MAT_ELEM (mat, AMM, line, cola). F2 = 326.0f;  

Update: OpenCV 2.0 for

Select a type to represent 1 element

Mat (or CvMat) has 3 dimensions: row, call, channel.
We can reach an element (or pixels) in the matrix

CV_32FC2 means element 2 with 32 channels Bit floating point value.
Elem is an acceptable representation in the code given above CV_32FC2 .

You can use other representations of your choice. For example:

  typedef struct elem_ {float val [2]; } Elem; Typedef struct elem_ {float x; Float y; } Elem;  

OpenCV2.0 adds some new types of elements to the element in the matrix, such as:

  template & lt; Typename _Tp, int cn & gt; Class CV_EXPORTS Vec // cxcore.hpp (208)  

so we can call Vec & lt; Float, 2 & gt; You can use to represent CV_32FC2 , or use:

  typedef Vec & lt; Float, 2 & gt; Vec2f; // cxcore.hpp (254)  

To find more types, see the source code that can represent your element.
Here we use the Vec2f

element 2

The easiest and most effective way to use the element in mat is Mat :: at .
There are 4 overloads in:

  templates & lt; Typename _Tp & gt; _Tp & amp; At (int y, int x); // cxcore.hpp (868) template & lt; Typename _Tp & gt; Const _Tp & amp; At (int y, int x) const; // cxcore.hpp (870) template & lt; Typename _Tp & gt; _Tp & amp; At (point pt); // cxcore.hpp (869) template & lt; Typename _Tp & gt; Const _Tp & amp; At (point pt) const; // cxcore.hpp (871) // cxmat.hpp (454-468) / we can use the element like this: mat m (size (3,3), cv_32 fc 2); Vec2f & amp; Elem = m.at & lt; Vec2f & gt; (Line, color); // or M.AT & lt; Vec2f & gt; (Point (call, line)); AMM [0] = 1212.0F; AMM [1] = 326.0F; Float c1 = m.at & lt; Vec2f & gt; (Line, color) [0]; // or M.AT & lt; Vec2f & gt; (Point (call, line)); Float c2 = m.at & lt; Vec2f & gt; (Line, color) [1]; M.T. & Lt; Vec2f & gt; (Line, color) [0] = 1986.0 f; M.A.T. & Lt; Vec2f & gt; (Line, color) [1] = 326.0F;  

Conversation with old interface

Mat gives two conversion actions:

  // headers Converts to CVMAT; No data has been copied // cxcore.hpp (829) operator cvmat () const; Converts the header to IplImage defined in // cxmat.hpp //; No data copied operator IplImage () const; // We can negotiate a mott object with the old interface: Mat new_matrix (...); CvMat old_matrix = new_matrix; // Be careful about your lifetime CV_MAT_ELEM (old_mat, elem, row, col) .f1 = 1212.0f;  

events - jquery add more to a click function -

I have a function that is bound to some JavaScript pages for some page objects that are loaded on every page .

I need to add some more functionality to the already defined event handler. Here's an example of what I mean here.

With the currently defined click event the object closes the pop-up division on the screen. When it is clicked (only on this fixed page), I need to reset some elements on this page.

Therefore, I can easily open click events, and make a custom one reboot, but it will have to copy a lot of code from the original closed event

if worse Worse, I can do this, but I would like to save the copy of that code for this special case.

Is there any way, more code for any insights?

c# - How to store System.Windows.Controls.Image to local disk -

How can I store on a System.Windows.Controls.Image disk that says: \ data \ 1 .jpg: thanks to

You might try some on the pattern of this method:

Private Zero SaveImageToJPEG (Image ImageToSave, string location) {RenderTargetBitmap renderTargetBitmap = New RenderTargetBitmap ((int) ImageToSave.Source.Width, (int) ImageToSave.Source.Height, 100, 100, PixelFormats.Default) ; RenderTargetBitmap.Render (ImageToSave); JPGbitmap encoder JPEGBitMapEncoder = new JPEGBitMapEncoder (); JpegBitmapEncoder.Frames.Add (BitmapFrame.Create (renderTargetBitmap)); (Filestream filestream = new filestream (location, Flamemode.)) Using {jpegBitmapEncoder.Save (fileStream); FileStream.Flush (); FileStream.Close (); }}

To get what you want, you may need to mess with the sizes in RenderTargetBitmap, but she should get a job. You can also use different encoders as compared to the JPEGMapmap encoder.

design - How to handle with older IE versions and webdesign? -

It may be completely wrong to deal with my blindness, but yes, now I am in a bad situation I am

Since the month I am making an auction platform, at the end of the project - the time limit is decreasing and now - we do a browser test with older browsers (for example, and worst : Ie6).

What should I say? The full design fails in IE6 logo is not transparent, log in to know the button in God that the monitor and the entire menu bar is 100px where IE 7, IE 8, Opera 10 and FF3 are all very fine, no The problem is not exactly right.

So, how can I handle this fact that my complete design in IE6 is simple unsuccessful? Any ideas to save my head? =)

First of all, do not panic. Layout work in IE 6 is not hard to do. Many things are possible with IE 6, you only have to do it in a slightly different way. This page does not take much time to get IE6 compatible (most of the time).

The main issues are from the top of my head:

• First, conditional comments are your friends to use them to drag IE6 versions of your CSS files.
• There is no transparent PNGs
• No clear: left or clear: right either transparent GIF, non-transparent images Or for IE 6 Transparent PNG hack. Simply use the clear: both .
• The list of the lists below shows up at the top of the lights below: There are many solutions available, either hide the dropdown or use the iframe trick before displaying the foreground div (one of the size of the foreground diva Create IFrame and place it under the divider below, which will hide the dropdown)
• No Status: fixed . You have to be with that you can try some code instead of status: absolute , but it will actually slow down. (Simply say, the speed of javascript execution is not one of the great powers of IE6).
• IE6 has CSS gradient and CSS shadow (like FF and Safari) but you access them differently, more to know the Google IE CSS filter.
• Try to use jQuery or some other JavaScript library, they hide very complexity and browser incompatibilities.
• The rest is negligible with dimensions only. It takes some time but it is not difficult.

Good luck!

e commerce - Is there an XML standard for Ecommerce Products? -

Is a standard way of transferring product data between e-commerce websites?

I think there are many cases where a company wants to include products from other companies inside its store, how will it be accomplished?

I think a XML feed is the way to go, but a standard for something on the lines of product names, product codes, stock levels, color options, image file names Is the price, discount eligibility etc.?

I know that Magatton uses XML / Import products, but is it based on a recognized standard?

I do not know whether e-commerce is specific to web sites or not. But of course, EDI (electronic data interchange) among businesses is somewhat more common to do. The standard is defined by NPO which is called. See their website for the name's standard.

multithreading - Building a multithreaded work-queue (consumer/producer) in C++ -

I have the following scenario: I have a thread that wants to fill a container with a pair of integers (summarize In, job description), and I have a large number of worker thread (8-16) that should take the element from this container and do some work.

I thought that the problem can be easily solved with a blocked queue - like removing items, synchronizing access to the thread queue, and sleeping if no data is available.

I (maybe wrong) I believe that something like that should be present in STL or Boost, but I am unable to find anything.

Do I really have to implement that thing myself? It seems that such a general scenario ...

If you apply it yourself, So implementation should be a fairly simple combination of a semaphore, muteux, and a line item.

Here's some pseudo-code:

  Generate {pthread_mutex_lock (& ​​amp; mutex); Queue.push_back (someObjectReference); Pthread_mutex_unlock (& ​​amp; amp; mutex); Sem_post (& amp; availabilitySem); } {Sem_wait (& amp; availability); Pthread_mutex_lock (& ​​amp; mutex); Queue.pop_front (someObjectReference); Pthread_mutext_unlock (& ​​amp; mutex); }  

java - HTTP Request (POST) field size limit & Request.BinaryRead in JSPs -

First of all, my Java is out loud and I have never used JSP or servlet, but I have to help someone else I am trying to solve a problem.

A form provided by Javascript is being posted back to JSP. Some of the fields in this form are more than 100KB size but when the form field is being received on the JSP side, the area value is being scaled down to 100 KB.

Now I know that there is such a problem in ASP request. Use the form which can get around from the request. Is BinarRed an equivalent in Java?

Or alternatively there is a single setting in WebSphere / Apache / IBM HTTP server that gets around the same problem?

Since the post request must be in-store to provide the functionality needed by the servlet server by the servlet container To be kept, most of the servlet containers have a configurable size limit to prevent dosage attacks, because otherwise a small number of bogus clients can excite the server to run out of memory.

This is a little strange, if the webspreader is quietly reducing the request rather than failing properly, but if this is the reason your problem is, you can get the configuration options.

   2. Rank items of items based on the purchase
   3. Return the top n items from the previous step

   I am working with the question given below:

     Deactivate @ Customerless (5), @ Producted Ent; Set @customerid = 'ALFKI'; Set @producted = 59; - Find other products from those customers - who have also bought my producer, in the top order, from 10 od.productid, c.categoryname, p.productname, p.unitsonorder, count (od.productid) [order details] od inner inner Order o o.orderid = od.orderid internal included product p.productid = od.productid in internal categories c c categorid = p.categoryid where o.customerid & lt; & Gt; @customed and odd.product & lt; & Gt; Group by @productid and p.discontinued = 0 od.productid, c.categoryname, p.productname, p.unitsonorder command 5 characters, 4 desc  

   I think my next step To break the query so that I can filter recently based on purchases (as opposed to all historical purchases) and match the customer compared to all the customers purchased by my customer. Can anybody provide any signal? Am I going in the right direction? Should I take a completely different direction?

   At this point, my goal is to display accuracy, because I know that I do not yet have the experience of implementing algorithms for their full benefit. I'm just trying to implement the concept. Once I am satisfied, I understand it well, I want to test this query against a larger database with more realistic customer data.

   text ">

   It is commonly called" market basket "analysis or" affinity group "and it is not as simple as it seems, due to most combinations. The first thing is that the minimum of cases For example, suppose we have 1 M baskets and 10 people who had bought the product B in the same basket as the product A had bought. In 10 cases, It is worth noting that "those who have bought it have also bought B". For this reason, using "recent" purchases is a bit difficult. This idea is to create a table of product pairs, but if we have N Products, The number is N * (N-1), so for 1000 product stores, we have 999000 combinations, so the algorithm which is not it is simple.

   The order of objects to consider one more thing And the value of each is for example cy Customers who purchase only can buy a "LED light" (add) But, if someone puts a LED light in a basket, then can the system present a bicycle in the list?

   In this meditation Keeping that you are using SQL Server, I use the "MS Association Algorithm" for this purpose to you , using the same data, you have your results against "business solution" The Lna can.

Get Application Server name or ip and port in Java -

We want to identify and display the server and port that is running behind a Java application proxy web server That returns the getServerName () and getServerPort () proxy and the server name of its port (80).

We have two application server examples that run on a physical box and therefore there are two active ports, ie the box is 9080, 9 081. Let me & lt; Application Server Name & gt ;: & lt; Application Server Port & gt; to display.

Any thoughts? I'm the whole Java Nob, sorry that this is a basic question.

Returns the local port.

Returns the local port.

Returns the local port.

c# - Same code acts differently on different machines - what might be the cause ? (CLR version issue ?) -

I fixed a problem debugging, where our program crashed on the production server, but never on development machines.

I have made this small program, with which I can reproduce the issue:

  using the system; Using System.Collections.Generic; Using System.Linq; Namespace runtimebug {class program {static zero main (string [] args) {var coll = new collection {{"" test, new data ()}, {"test2", new data ()}}; Var datacuesen = coll.Cast & lt; Data & gt; (). ToList (); Console.WriteLine (dataSequence.Count); }} Category Archive: Dictionary & lt; String, Data & gt ;, IEnumerable & lt; Data & gt; {The public new INMM & lt; Data & gt; GetEnumerator () {value in value v (value v) {yield returns} v; }} Class data {}}  

while printing on my machine, this code prints "2". While running on the production server, it fails with the following exceptions:

  Unchecked exception: System. UnknownCast exception: Unable to remove type 'object'. System.Collections.Generic.KeyValuePair `2 [System. To type string, runtime bug.Data 'RunTimeBug.Data' on System.Linq.Enumerable & lt; CastIterator & gt; D__b0`1.MoveNext () on system Colllections.Generic.List`1 .. on the system (IEnumerable `1 archive) system. In LINQ.Enumerable.ToList [TSource] (IEnumerable `1 source) RunTimeBug.Program.Main (string [] args)  

On these machines I can only find the difference, that is Version 2.0.50727.4927 on CLR runtime machines, where it works, and on version 2.0.50727.1433 machines where it does not work.

As far as I can tell, the cast extension method gets the wrong version of IEnumerable on older machines, but "right" on a new machine.

Can anyone explain why I see this? What has changed in the 2 CLR runtime versions, due to which can it be?

Please note, I have already set up, and I know that the collection class in the above code is poor design because it implements 2 different IEnumerable found in our product "in the wild" , So I really want to know the exact reason.

I think Jason has mentioned the fix mentioned in that article in which your code will be later Have to work on release. I do not have access to the Pre-SP1 version of Enumerable. Cost is a bit difficult to guess.

One thing is for sure: Once this code creates an enumerable table. The catastator () is not guaranteed to work in your case. It sets an iterator to convert IEnumerable to IEnumerable & lt;> and is the GetEnumerator () to initialize the itater block to iter block. It can only make a dictionary call. The gate annotator (), does not make the keyValuePair casting that data will fail if this IEnumerable return fails, because the exception tells you.

The current version of Enumerable.Cast () tries to turn on IEnumerable & lt;> and the works that the creator () is not used.

How to chain these constructors (C#)? -

I'm getting the concept of reducing consultants, but I did not know that these two special constructors together, therefore I appreciate it if someone can help me

constructor

  // default constructor // Objective: to minimize data members Start / Parameters for: None // Returns: Any Public Line () {startPoint.xCoord = 0; StartPoint.yCoord = 0; EndPoint.xCoord = 0; EndPoint.yCoord = 0; } // Parametragged Constructor // Purpose: Start the data for P1 and P2 parameters to the members: Points and P2 / Returns: Any public line (Point P1, Point P2) {startPoint = p1 ; End Point = P2; }  

  public line (): this (new point (), new Point ()) {}

Efficient Linux sockets (DMA/zero-copy) -

I am creating a very high performance Linux server (based on Apollo, non blocking sockets, and async disk IO [Based on Io_submit / io_getevents / eventfd)). Some of my standards tell me that the way I handle sockets is not enough for my needs, especially, I'm concerned about receiving data from a network card with a userspace buffer and receiving data on the userspace buffer from the network card ( For now ignore the sendfile call).

Calling on reading / writing on non-blocked Linux sockets, which I think is not completely asynchronous - this system makes call blocks while copying buffers from userspace to the kernel (or on the other side) , And then only get returns. Is there any way to avoid this thing in Linux? Specifically, is there a completely asynchronous writing call that I can create on a socket which will return immediately, DMA will set userbus buffer as essentially a network card, and set event / issue upon completion? I know that this is an interface for Windows, but I did not find anything about it in Linux.

Thank you!

There was some discussion about providing an API with some lines recently on the Linux kernel , But the sticking point is that you can not do DMA from the common user-space buffers with the network card because:

• Userspace looks like infected data in linear address space, probably not in physical memory , Which is a problem if the network card collects Skeeter-DMA Does not;
• On most machines, all physical memory addresses are not "DMA-enabled"

On recent colonies, you can see the vmsplice and Can try to use. You want to send - vmsplice pages (with SPLICE_F_GIFT ) in pipes, then pairing with them in the socket ( With SPLICE_F_MOVE ).

how to create windows 7 jump lists via python/pyqt? -

I have a pyqt project that I am interested in using to play with the new window 7 jump list feature;

Has anyone found an easy way to stop it here? Is the pywin32 module marks of Hammond a proper cover?

Thank you!

I don 'q' have not supported jump lists, you can get a little more info

Support for Qt 4.6 Windows 7 has been added and it was released today but I do not think that they have added this specific feature and I do not think that PETT supports this release.

c# - Chess Logic in XNA -

So I have created a 2D Chess Game Board with all the pieces using the XNA Library and all. Although I do not know how to run pieces, if I click them. This is one of my knighthood arguments.

  if pressed (mouse.LeftButton == buttonstate and mouse.x == wknight1.position.X & amp;; Amp; mouse.W == wknight1.position.Y) { }  

How do I select the piece to allow it to move?

I'm not particularly familiar with XNA but I will give some suggestions. For one thing, you probably want to place the piece in the 2D array or instead of being in its own variables (like wknight1). Otherwise, you have to check each variable the user clicks on.

I'm assuming that you want a system, where the user clicks on a piece to select it, then clicks on an empty square to clear it. Here are some pseudo-codes, such as (I mean an empty square here means an empty square):

  if pressed (mouse.LeftButton == buttonstate & amp; Board [mouse.x] [mouse]!! = Null & amp; fragment selected == tap) {piece selection = board [mouse.x] [mouse];; SelectX = mouse.x; SelectY = mouse.y} and if (mouse leftbutton == buttonstate.Pressing & amp; board [mouse.x] [mouse] == blank and select pseudo! = Null) {board [selected x] [ Selected w] == faucet; Board [mouse.x] [mouse.] = Fragment selected; Piece selection = null; }  

You can add in such situations as isAvalidMove (piece type, starks, starkey, finish, finish) where you check that the player is trying to move his piece and It is a legal chess take etc. You can probably make it even more elegant (and / or event-driven) (and add-click-and-drag etc.), but I keep it easy to explain basic logic.

delphi - Is an update to D2010 really meaningful -

I am trying to migrate my own projects in Delphi 2010. But it seems very difficult.

1. I use TntControls for older projects. If I remove this library, then some runtime functions should be implemented by me again. For example: Convert UnicodeString to a specified code page.
2. "SizeOf", "Length", FillChar () still confuses me, the compiler will throw a warning, if SizeOf () should be replaced with length () but I'm stupid for me - Secure Tutorials are not found.
3. A misleading warning, when trying to insert an anestring into the Unicode string. This conversation will not let you lose any data, right?
4. Many codes (zip, string utility, etc.) should be re-entered.

Too much headache ... Can Delphi share the experience of migrating existing projects by an existing Delphi 2010?

The compiler warns you when changing the UnicodeString from AnsiString because it is not a simple string assignment, but a conversion guarantees to allocate more memory and at the same time the same character Copies. This is a demonstration warning, not a data-loss warning. Conversions both in the opposite direction (even when specifying Utf8String, which technically will never lose data from UnicodeString, if it is only filled with valid Unicode characters). The best way to avoid warning is to avoid using an anise string in the first place. Except such codes, use plain old string, which in fact requires the code page to know how to encode things.

I do not think the "retention" argument is very strong. Library code should specifically contain unit tests that you have re-compiled every time. Check again is something that you do several times a day;

There is no special effort involved.

python - How can I use pywin32 with a virtualenv without having to include the host environment's site-packages folder? -

I am working with Python 2.6 which is partly supported due to the messenger that was revealed by MS Which now affects Python as it is now compiled by MSVC 8.

The problem is that the manifest depends on the embedding support extension, so that can be a pain because the host site-package is created without the folder (Kinda beat the point in a built environment) I installed the required extension Can not find a way to do so that they are accessible to PyInstaller.

Has anyone got the solution to this issue?

I found (now a dead link) that offered the following solution:

1. Browse for the URL of the excel
2. Activate your VirtualEngine
3. Play easy_install http://PATH.TO/EXE/ DOWNLOAD

   This setup works with the latest versions of Autolocks (approximately February 2014, reported by Tovemed in comments).

   ---

   If you are using an earlier version of SetupOut or merged it back into Setup Tools), you may receive this error message:

   Error: c: \ users \ blah \ appdata \ local \ temp \ easy_install-ibkzv7 \ pywin32-214.win32 -py2.6.exe A legitimate distutils Windows. Exe

   In case that is not:

   1. Exe download yourself
   2. Activate your VirtualEngine < Li> Trying to run easy_install DOWNLOADED_FILE.exe

   ---

   I hope you try "Pip installation" instead of "easy_install" but this work Never, and will never happen (CI Finally, I found, but did not test the solution on which:

   Resolve it in my copy of the pywin32.pth file Virtualenv site -packages and paths Edit the file to indicate.

   If other options do not work for you, then maybe it will?

java - How to control logging level in client library? -

We want customers to be able to control the logging level in our client JR. What is the best way to do this?

We currently have only a few statements that write to System.out. I know Log4J will solve this problem, though one of our biggest clients does not use Log4J and uses its custom logging implementation. Is there a clean approach to entering our client jar?

The option we have considered: To set the logging level for clients, client can set special properties on jar classes (do not like it), our client jar can read an alternative . The properties file that clients can keep on their class (better but still a bit of a pain).

Do not use a solid logging framework, so that you can exchange logging if You need it for the first time I start changing my system. Out was included in java.util.logging.

If your customer uses any other logging framework, then either there is a bridge slf4j or you can write your own too.

EDIT: We used it to simplify the entry of those external libraries which LOG4J is used in java.util.loogging which we use.

embedded - Lua certified for use on an airframe or road vehicle? -

Does anyone know if Lua has been certified to run on an airframe or road vehicle? Certification procedures such as DO178B (RTCA) or standardization such as ISO 26262 (road vehicles).

Certification is the case and I will feel more confident of the language which should be realized that another company has successfully processed a process.

I am not making any condition due to GC and dynamic facilities, but I thought I would question the crowd anyway. Cheers.

coding style - Logical value of an assignment in C -

  जबकि (curr_data [1]! = (अहस्ताक्षरित int) NULL & amp; ((curr_ptr = (शून्य *) Curr_data [1]) 1))  

दो भाग प्रश्न।

क्या होगा (curr_ptr = (शून्य *) curr_data [1] ) मूल्यांकन, तार्किक रूप से TRUE ?

इसके अलावा, मैं इसके बजाय हैक-आईश जानता हूं, लेकिन जबकि स्टेटमेंट कानूनी सी है? मुझे कोड में कहीं और असाइनमेंट डाल देने के लिए महान contortions के माध्यम से जाना होगा, तो मैं वास्तव में अच्छा होगा अगर मैं इसे वहाँ छोड़ सकता है, लेकिन अगर यह इतना बड़ा है कि यह हर किसी की आंखों में लपटों में फट जाएगा, मैं इसे बदल दूँगा ।

अपने प्रश्नों का उत्तर देने के लिए:

1. यह सच का मूल्यांकन करेगा अगर curr_ptr को NULL पर सेट नहीं किया गया है (अर्थात curr_data [1] नहीं है 0)।
2. मुझे विश्वास है यह कानूनी है, लेकिन इस लाइन की कोड के साथ बड़ी समस्याएं हैं।

फिर भी, मैं मान रहा हूँ कि आपने यह कोड नहीं लिखा है, क्योंकि आप इसे बनाम छोड़ने के बारे में बहस कर रहे हैं। इसे बाहर ले जा रहा है तो मैं चाहता हूं कि आप यह पता करें कि कोड की यह रेखा किसने लिखा है और उन्हें भारी कुंद वस्तु में पेश किया है।

1. (अहस्ताक्षरित int) NULL हास्यास्पद है आप ऐसा क्यों करेंगे? यह संभवतः 0 लिखने के समान ही होगा (सुनिश्चित नहीं है कि यह मानक द्वारा गारंटीकृत है)।
2. curr_data [1] में किस तरह का डेटा है? कोड> यदि इसे एक सूचक में डाला जा रहा है (और संकेतक इसे डाली जा रहे हैं)? यदि यह एक अभिन्न प्रकार के रूप में एक संकेतक धारण करना माना जाता है, तो आपको intptr_t या uintptr_t & lt; stdint.h & gt; में दी गई प्रकार का उपयोग करना चाहिए उस प्रयोजन के लिए (यदि आप संकलक हैं तो C99 ptrdiff_t को स्वीकार्य विकल्प नहीं हो सकता है)।
3. || 1 अंत में बेमानी हो रहा है यदि curr_ptr = (शून्य *) curr_data [1] झूठी मूल्यांकन किया गया होता, तो हम इसे पहले शर्त में पकड़े होते।

यह एक दर्द हो सकता है गधा में, लेकिन इस पंक्ति को फिर से लिखने पर गंभीरता से पुनर्विचार। यह IOCCC में एक प्रविष्टि की तरह दिखता है।

Progress messages - user experience -

You display normal messages when displaying progress bar, like:

• "Working "
• Loading more granular messages, such as
• " as a result of improved user experience of additional encryption efforts "
• " in progress "
• " Team ""
• "POL10283 Saving"
• "Case 2 of 5 is loading"
• "Team loading"
• "POL10283 Saving"

In addition, if you donate If we conduct the Dar messages, what do you control them from those objects which they relate, or sweeping views / modules which object to load?

Mark

This makes a significant improvement in the applicability if you send the message to the user To tell how much time is left till the task is finished.

So there is definitely better than some "processing" like "processing items 2"

I also advise to avoid running from progress bars until it is finished, then just a profit and repeatedly it seems to tease users only: " It will be done in one minute. Ok, maybe in a minute.
