• .NET Development WM_MOUSEWHEEL

  Hi Here is the topic I wish to find an answer too... I have an application running on my lap top which should trap the WM_MOUSEWHEEL message allowing me to scroll backward and forward through my data. However, the high word of wParam is always zero even though the low word reports the shift/alt/cap status correctly. I have confirmed that my window has input focus and that GetSystemMetrics(SM_MOUSEWHEELPRESENT) returns true. Any ideas why this should be My only thought is that I'm using a laptop which has a local mouse pad and I also have a USB mouse. How does windows discriminate between the sources of wheel messages, or does it simply just 'OR' them together Odd problem, never seen or heard of that before. Sou ...Show All

• Audio and Video Development Scaling still does not affect the renderer dimensions

  Hi I asked about this problem and got an answer that it was fixed here: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=718158&SiteID=1&mode=1 But it still seems to do not work as it should. The problem: I built MFT that performs 2x scaling with input type YV12, NV12 or YUY2. To test it I use a player that based on the PlaybackFX SDK sample. When the output type is YV12, everything is OK and I get the scaled dimensions from the renderer using GetNativeVideoSize(). When the output type is NV12 or YUY2 the GetNativeVideoSize() returns the original dimensions of the video and what I see is a quarter of the frame. I also tried to set it manually with the correct size but it only stretched the quarter and did not display the ...Show All

• Visual Studio Express Editions Create Text Box Array

  Hi there, I'm trying to create an array of text boxes, so that I can easily iterate through them in a for loop, but I'm unable to figure out how to do this, either in the GUI designer or in the code. Any help on how this can be accomplished would be greatly appreciated! Thanks! you can do this programmatically:   TextBox[] theTextBoxes = new TextBox[ size ];     of course replace "size" with the number of textboxes you wish to create. This creates an array of textboxes of the size you have specified.  Then simply iterate through each one and do whatever you want with them, example:     foreach (TextBox curControl in theTextBoxes) {   ...Show All

• Visual Studio 2008 (Pre-release) Is there any type of context available at time of IAuthorizationPolicy evaluation?

  I've been doing some work with adding custom context to our WCF web services. I've successfully added context to the operation and instance context, but now I'm doing some work at the IAuthorizationPolicy level and finding out that the contexts that I've hooked so far (i.e. operation context and instance context) are not available yet at this point. First, is there a context that flows all the way through all these layers of a WCF request Second, I cannot find any good documentation on what the life cycle of a request looks. If I could find that I would probably be able to figure the rest out on my own. TIA, Drew Well, we have a custom context of our own in which we cache of data. I never want ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Blue Screen of Death or System Restart

  I have XNA installed on my home computer, and on my laptop, and it happens rather often (a few times a day) that when I try run the project, or click the Save All button, I get a system reboot or a BSOD. It happened once too when I tried to move a file to another folder, in the Solution Explorer. Since it happens on two different computers, I was wondering if someone else has had the same problem. Any known bug/solution Thank you! Unfortunately, installing the Visual C# SP1 did not solve the problem. I've also made sure to update my drivers, to no extent so far. The blue screen itself doesn't present any other information beside the STOP code I mentioned before. It does howe ...Show All
