Game Technologies: DirectX, XNA, XACT, etc. Drawing into the ZBuffer
I wish to "clear draw" a perimitive into the ZBuffer. What I mean is, I want to draw the geometry of a mesh or perimitive into the ZBuffer, where in each place a pixel should be drawen, the ZBuffer value in that place will be set to 1. How can I accomplish this Thanks. Did you mean post transformed POSITIONT is an already transformed vertex. However, how do I set or clear the ZBuffer value in the pixel shader By the way, I didnt get an alert for your reply and I didnt mark it as answered and it was marked as answered. You have an idea why ...Show All

Visual Studio Team System Intermittent bad performance and errors
Hi, Intermittently (perhaps once a month), I see very bad performance on a TFS server and have error messages like the following. TF50804: The TFSServerScheduler service could not complete the scheduled task at: http://uscavstfs:8080/warehouse/v1.0/WarehouseController.asmx The web service returned the following error: The operation has timed out. After restarting the server (it's that unresponsive), browsing to the page indicated and executing the run method to manually process the warehouse succeeds without error, and fairly quickly. Some short time later, the performance problem resurfaces and the error shows up again in the log. When this happened previously, it seemed to clear itself up after awhile. Any troubleshooting ide ...Show All
Visual C++ CString corruption
This has happened before. I have data stored in a CString. I use atof to convert it. And I get this crazy number. And so I output using a message box and the number seems just fine as a string. So I then go to output it to a file as a string and a number and the string returns (null) and the number is all crazy. But write after I write the data to the file and I call messagebox the string is just fine. I'll post my code snippit. I have no idea whats happening. int count = -1; // Parse Data fin = fopen( "output.txt" , "w" ); for ( int i = 0; i < lines.GetCount(); i++) { if (lines [0] == '/' ) { // Start a new Data Series m_SeriesData.push_back(myData); myData.Clear(); ...Show All

Visual Studio Sandcastle: Referencing generic types
Hi, i'm using the September CTP of Sandcastle and building a chm, and i would like to know the proper way to indicate a generic type inside a cref reference. For me, the following comment segment: /// <remarks> Please refer to <see cref="ArrayList.BinarySearch{T}(T, int, int, object)"/> for details. </remarks> comes out as: Remarks Please refer to !:ArrayList.BinarySearch<T>(T, int, int, object) for details. I note that there is currently a bug with cref's pointing to Framework types which explains why it isn't a clickable hyperlink, but what has caused the "!:" at the start of the ArrayList type Also, while i am at it, the following comment structure: ...Show All
SQL Server How to check out our cluster remotely?
Hi everyone, Primary platform on client is XP Pro sp2 and on server Win2003 Ad.Server 64-bit We're looking for any snippet or link related with Clustering instantiating. We need to call our remote cluster from an ASP 3.0 page and check out if one of our Active Resource is up (in this case is a .net service) . We suppose that it should be done for each node. It's an Active-Passive cluster. Thanks for your time, Just connect to the virtual host name that is part of the SQL Resource Group, and make a query. Coding technique should be no different for a cluster than any other remote connection - just use the name of the virtual host instead of the physical one, and the connection gets automatica ...Show All
Visual Studio 2008 (Pre-release) Can an application either provide a service or consume the service
I am trying to write a highly available Windows Service application, hosting a WCF service. There may be multiple instances running on multiple computers. However, only one of them is the master providing the WCF service and the rest of them are in the standby mode. I am thinking of adding a method to the WCF service so that the master and standby instances can communicate. This means that a standby instance needs to create a proxy of the WCF service. Since the code base is the same, it implies that it needs either to provide the service or to consume the service. It does not seem possible if there are data contracts and the call involves them. While I did get it to work when the data contracts are not involved, the workaround involves man ...Show All

Visual C++ Sending CB_GETCOMBOBOXINFO Message in a Winform Application
Hi, Trying to send the message by use of SendMessage function to a ComboBox control, first the compiler does not see the defined value of the CB_GETCOMBOBOXINFO, although the windows.h header file is added to the project. Still, have added the actual 0x0164 value of the message-constant to the code, the compiler generates errors regarding the four arguments required by the SendMessage routine. Any links to proper documentation for this task, or comments Best Regards, Reza Bemanian Have checked the checkbox as you pointed to in your reply, fixed the problem. Now it both compiles and links. I have not run it yet to look at the info structure, but hopefully it works accordingly. Thanks for your repl ...Show All
