When I try to open only this particular from in a new project , I am not able to do so. Please help.

This should add all three files to you project and the solution explorer will display the correct icon that the form has been added. This separation of the form into 3 files occurs ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. GraphicsStream.Write not writing as expected

  I have a method where I write a 2d array into a texture. It is used for running some ordinary calculations on the gpu. private void writeToInputTexture( Vector4 [,] inputData, Texture inputTexture) { GraphicsStream graphicsStream = inputTexture.LockRectangle(0, LockFlags .None); unsafe { Vector4 * textureData = ( Vector4 *)graphicsStream.InternalDataPointer; for ( int y = 0; y < dataHeight; y++) for ( int x = 0; x < dataWidth; x++) textureData[x + y * dataWidth] = inputData[x, y]; } inputTexture.UnlockRectangle(0); } That works as expected.

  How do I detect if IE (or any program) is running on the target machine from a Visual Studio Setup Project I want to check this as a launch condition prior to starting the setup. Thanks.

• Game Technologies: DirectX, XNA, XACT, etc. Xbox Live Arcade

  Do any of you reckon that it's possible to make a game using the XNA express framework, and then get it published (by MS or otherwise). I think, looking at the standard of games on Xbox Live Arcade, that I can make a much better game than anything there. I'm guessing the XNA Professional will be reasonably priced ... $100 give or take. I read something about having to subscribe to some annual "service" for roughly the same amount. Not sure if that gets you access to XNA Professional, or just the rights to even think about publishing. Or both ;) The tough part will be Cert. Full TRCs I imagine, which are non-trivial (or is it TCRs can't recall which belongs to Msft and which to ... other .. ...Show All

• .NET Development HOW TO DELETE RECORD IN A DATABASE ?

Furthermore, they will handle strings in such a way as to prevent SQL injection hacker attacks when you are wri ...Show All

• Gadgets Gadget behavior on spaces vs live.com?

  I am still working on my first gadget and noticed things work really different on live.com compared to spaces. If you want to load what I have so far and see what I mean, the manifest can be found at http://www.incendy.com/MyRSS/rssgadget3.xml Basically the css is very different and also the function that rebuilds the list does not really work on Spaces and you have to manually refresh the page to get the new feed. Just curious if others have experienced this and have advice on what I should be doing differently. The function getfeed gets called but the content seems to be cached on Spaces where it works fine on live.com!

• Visual C++ Mixed mode C++/CLI idiom

  In my C++/CLI components, for each component I create a ref CLR class and a C++ class, the latter which does most of the internal processing and interfaces to the C++ standard library and 3rd party libraries such as Boost. I do this so I can use C++ libraries in my CLR component, especially when the .Net framework does not offer all the facilities which 3rd party C++ libraries have. In order to allow the C++ class to access the properties, methods, and events of the corresponding CLR class I have a pointer to the C++ class as a private member of my CLR class and dynamically create an object of the C++ class, passing a pointer ( ^ ) to the CLR object to the constructor of the C++ class, and assign the resulting C++ object to the pointer in ...Show All

• Architecture Performance issue become worse upon split out Web Applications into web server and DB server

  Hi, Currenly i'm faced web applications (in web server, 2GB RAM) with performance issues upon seperated database(4GB RAM) and web application into 2 machines. Before spliting, it have performance issue where IIS need to be reset when "Server is un-available" or hanging occur.

• Visual C# how to return null from a constructor

  say, i a m trying to do something like: class something something(streamreader){ if (wrong format or end of file) caller receives null as result else build object from what has been read in file } i tried 'return null', but it says it can not do that since a constructor is 'void', so i can not place a return sentence. i'm not sure something like this.dispose would retunr a null, since the 'dispose' may be asynchronous (or something) i have the next alternative class something blah blah somehting(string) (build object from string, check if string==null or wrong format before calling) static bool checkformat(string) check to see if string is adecuate to build somet ...Show All

• Microsoft ISV Community Center Forums Word: Normal.dot template menu bar

  I have programmatically modified the Normal.dot menubar (adding more dummy options), and I want to get rid of all of them, permanently, to return to the original state and appearance of Normal. dot.... How can I achieve that, please thanks Here is some general information from one of our engineers that might be helpful. Firstly, I’m not very sure how the ISV would like to reset the settings. However, to work around this problem, you must rename the Normal.dot global template. Word will re-create the template when you start the program. To rename the Normal.dot global template for Microsoft Office Word 2003, follow these steps: 1. Right-click Start and then click Explore . 2. Double-click the ...Show All

• Visual Basic Backgroundworker Fundamentals

  Are these background workers slow or what If you give it a simple 2-3 lines of codes, it could take a long time for it to execute. No, that's not true. The background worker will execut the code but it appears to have amensia, because the error - thread cannot run multiple tasks at the same time... which means, even though it has finished running the code, it cannot automatically dispose itself and therefore is still active until some element deactivate it. Oh, I can understand on a single core CPU, it might have to "wait" until it turn is up - but come on, on a dual core... what's the wait I don't suppose if you tell ******** to give more processing power to background services would help ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA framework for non C#

  One of the great advantages of the .NET framework is that developers can work on the same project in different programming languages. As I'm reading about XNA, it seems that this will not be possible with the XNA framework. Will the only programming language that has access to the XNA framework be C# I believe Microsoft should support a VB compiler and documentation. I am a VB programmer, I have considered moving to C#, but from what I have heard there is a productivity hit. And anyway if Microsoft is going after the hobbyist market then there is no better language than VB. Alternatively Microsoft could offer XNA C# documentation specifically for beginner programmers just to get people using programming and then move them onto creati ...Show All

• SQL Server Split the file

  my ssis package downloades the text file from Ftp. iT downloades for ex 5 files. I want to split the file to smaller file after downloades. If the size of file is more then 600 mB then I want to split it into 6 files. please suggest if any task in SSIS can perform this or any other way. Two ways I can see how to do this. 1 - Use a Script Task and the System.IO namespace stream objects to read the file and write out into several files. Change files based data size, rows or whatever. 2 - Use a Data Flow, with Flat File source. Then split the flow into several outputs and direct to seperate flat file destinations. There are two ways to do the split that I can think of. You could write a Scrip ...Show All
