• Game Technologies: DirectX, XNA, XACT, etc. Problems with AddService()

  Hi! I have been working with XNA for about 2 weeks now and I am new to the C# language. In my game I have a TextureManager and I wanted to give every class access to it. So I thought Game Services are a great idea, but it doesn't work right. In the Texturemanager-Class constructor I add it into the Services: Services.AddService(typeof(Texturemanager), this); Then I made an instance from the Texturemanager in my MainClass and after it I wanted to get the object back. ITexturemanager texturemanager = (ITexturemanager)Services.GetService(typeof(ITexturemanager)); But the texturemanager value is always null! Why doesn't it work right thx cya, Stefan sheepsteak wrote: Not sure whether it's just ...Show All

• Visual Studio Help going to home page

  Hey everyone. Any time I click on help. Be it through the start menu or through a app menu it skips the help file and instead navigates to my home page. So I can not access any help or documentation. Any help would be appericated. There may be a problem with those two specific collections. There first one you indicated is Patterns and Practices and the second one is WSE (Web Service Enhancements). Both of those are fairly old content and their installations may have been corrupted for some reason. Have you tried doing a repair on either one of those from Add/Remove Programs Also, when launching help from Visual Studio, can you tell me which version of VS you are working with Have you also tried doi ...Show All

• SQL Server Disable HideDuplicates from Report Builder

  I have some business analysts (I guess Microsoft would call them Information Workers) using Report Builder to design reports, but also as a querying tool. They often times dump the results of their reports/queries into Excel, do some crunching, and then come back to write a better report. When the Report Builder builds groups, it inherently turns on the HideDuplicates property / element so that it only displays distinct values on the group by fields. This looks great on a report, but is impractical for Excel, where the data is going to be manipulated by row. In the .rdl, I found the element "HideDuplicates" http://msdn2.microsoft.com/en-us/library/ms152916.aspx controls this behavior of the report. However, I cannot find an ...Show All

• Visual C++ Unexpected namespace pollution in VC8 (bug?)

  Running Visual Studio 2005 Professional, no service pack applied. Here is a code snippet distilled from some code that fails due to unexpected namespace conflicts: namespace ns1 { typedef unsigned long ns_t; struct base { ~base() {} }; } namespace ns2 { using namespace ns1; struct dummy : public base { }; } namespace ns3 { struct dummy2 { dummy2() {} ns2::dummy m_dummy; }; } ns_t ns_check; //compilation should fail here!! The above code compiles fine on my machine. The problem is that , for some reason, ns_t is visible at the global namespace when it shouldn't be. Strangely, removing base::~base will cause the behavior I expect (compilation error). I'm not sure exactly where the bug is and what a workaround ...Show All

• SQL Server more membership in "master.sys.login_token" than "net group"

  Hi. I'm investigating whether I can lock down a feature exclusively to only those who belong to a certain domain group. From what I understand, the master.sys.login_token view holds information on all the groups I'm a part of. However, I'm looking at the output from SELECT * FROM master.sys.login_token and see a number of groups that I can't verify I have access to. I have even run the DOS command " net group <domaingroup> /dom " and don't see myself listed in its output. Is this normal Is the output a culmination of everyone logged in at the time @@version = 9.00.2047.00 Thanks for your quick response.... I guess what's shocking me more than anything is the fact that sys.lo ...Show All

• Visual Studio Team System How to display the last checked in date / time for files in the Source Control Explorer GUI

  I have two questions. How can we display the last checked in date / time for files in the Source Control Explorer GUI How can we display the last label for files in the Source Control Explorer GUI If I could do those two things, I would be very very happy since I could do them in VSS, and I was very used to being able to do it. I feel as if I am missing something.... We’d like to add more columns in a future version of Team Explorer. Unfortunately I don’t think there’s an extensibility point for 3rd parties to do so. ...Show All

• Visual Studio Problems building documentation for generic classes with Sandcastle

  Using the December CTP of Sandcastle, I'm having problems generating documentation for generic classes... No documentation is made from these classes (or their methods) at all, but it works fine for other, non-generic, classes in the same project. Example class: /// <summary> /// My generic class /// </summary> /// <typeparam name="T"> my object </typeparam> public class MyGenericClass <T> where T : MyObject , new () { //... } Is this a bug in Sandcastle, or am I doing something wrong here Oyvind, We had a bug on this issue.
