• Game Technologies: DirectX, XNA, XACT, etc. Microsoft Directx SDK

  When I dont have any directx sdk installed, which should I download I noticed that DirectX SDK August has update behind it's name. And it has not all the same examples / tutorials as earlier sdk's. But when I download all sdk's from directx9, I have a lot of double data on my pc :( G'day! Though it says it's an "Update", it is actually a stand-alone package so you don't need to download any other DX SDKs. As things change samples are occasionally removed and new ones added.  If you really need an older sample you can unzip the SDK archive that has it and copy out the sample code, you don't need to install it or keep the ...Show All

• Visual Studio Team System All Unit Tests abort immediately

  I've been using the TestManager extensively in Studio 2005 Team Version for months running dozens of unit tests as I develop. Recently, every time I try to run a unit test *in Debug mode*, it aborts immediately with no message. When I open the test results, all I get is this: Test Name: <test name> Result: Aborted Duration: 00:00:00 Computer Name... Start Time: 1/1/0001 12:00:00 AM End Time: (the real date time) That's it. Not a word more. And ALL unit tests are doing this, even ones that used to run just fine. If I just run them, they run fine, but I absolutely cannot run them in Debug mode! Very bizzarr ...Show All

• Windows Forms Trouble drawing theme elements transparently

  I'm trying to draw a windows theme element (the window close button, specifically) to an image, and whenever I do, the image has ragged non-transparent bits. I got this code from a sample that didn't do this (it was all owner-drawn, mine draws to an image.) Any idea why it won't draw with full transparency Bitmap output = new Bitmap(closeButton.Width, closeButton.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb); Graphics fx = Graphics.FromImage(output);        IntPtr hTheme = OpenThemeData (Handle, "Window");           Rectangle rClose = new Rectang ...Show All

• Visual Studio Tools for Office Server Data Scenarios

  Hi We are going to migrate a windows app to a web app. The legacy win app used unmanaged code with COM interfaces in order to perform process like "MailMerge" on words docs (and other processes but the mailmerge is the main one). Well, with the new web app we are going to analyze a solution for the Office integration issues. We have not decided if to migrate to a server solution or to a client one. Scenarios: 1) Server with Office Primary Interop Assemblies. Advantages: data sources are locally on the server, template can be on the server. Disadvantages: PIA's are anyway COM wrapper, performances and scalability issues. ...Show All

• Visual Studio Team System Checking in a "checkout" lock on a branch?

  Wow this strikes me as odd.  If I want to "lock" a branch, say a checkout lock, I then have to "checkin" that checkout lock.  That's a tad confusing.  I would have guessed that applying a lock was an immediate action like applying a label. I think we (if I may lump Keith in with myself) already do think of lock as a status on a file, which is exactly why showing a lock as a "pending checkin" is confusing. Every other SCC system I've used shows a "Status" column instead of a "Pending Change" column (current state versus future-state).  In the case of VSTF, you're showing the future state in ...Show All

• .NET Development Socket.EndReceive question - in which scenarios does it return 0 (zero)?

  Hi, I have an application that works just fine. I am puzzled by the following issue though - in certain scenarios, Socket.EndReceive returns 0 bytes. According to the documentation, this happens when the remote host calls Socket.Shutdown or closes the Socket in another manner. Generally, I observe this to be correct . However, there are several types of apps (remote hosts) for which this does not hold (the code is not mine so I cannot see what these apps are doing). Even though EndReceive returns 0 (zero) bytes, the remote host is still connected (Connected property of the Socket is true). Not only that, but if I call BeginReceive agai ...Show All
