• Game Technologies: DirectX, XNA, XACT, etc. Rather noobish question to do with coordinates

  Hello, I am working on an application and one of the tasks it needs to do is apply a form of gravity to the scene. Now, we all know that gravity pulls down and so on, but with the mesh, it seems y is not always the vertical axis. The mesh is rotatable, but I just cant think where to start looking or indeed what to search for in terms of finding theory or a tutorial to find which way is down (in vector form). I assume it is to do with the camera or view matrix, but I cant think what function to call etc etc and I'm totally lost. Not yet in a spiral of tears, but if anyone can think of what I am on about and point me towards a tutorial, or something similar, I would be very greatful as according to my app at the moment, gravity applies in s ...Show All

• SQL Server BUG: UPDATE updates not listed fields

  Hi Everybody, I am in this forum for a first time. Today, I think, I found a bug in SQL Server 2000. I tried it on SQL Server 2005 and it is alive yet. Before I explain exact the problem I have a stupid question. Is there any type of award if I have found a real bug. It is about a situation when I try to update some fields in a table and I get updated some other wrong fields. There aren't any triggers ot something else. Create a new table, insert one row, update some fields but other ones get changed too. Is there something known about this Thanks, Hristo. I am with Microsoft SQL Server 2000 - 8.00.194 On my version and other ones (without SP) BUG10 changes to 0. It seem that this is fixed i ...Show All

• SQL Server Parameterized Expression

  I am trying to write an expression based on a parameter for a text box. If I write it without the parameter it works fine, but when I add the parameter, the expression evaluates as just text. My dataset contains a field called "PeakSessions" I have a parameter called "chrt", type string, containing the value "PeakSessions". =Fields!PeakSessions.Value <= Works fine. Displays the PeakSession data. ="Fields!" & Parameters!chrt.Value & ".Value" This parameterized version evaluates to: Fields!PeakSessions.Value. So it seems the parameter resolved correctly, but my expression is being evaluated as text. What am I doing wrong SQL 2005 Reports Services, SP1, Standard Edit ...Show All

• Visual Studio 2008 (Pre-release) HelloWorld logging problem

  Hi, Well, I was working on this very simple yet useful tutorial. http://wcf.netfx3.com/content/BuildingHelloWorld.aspx Then everything was going well till I reached the "Setting Up Logging" section. I followed the instruction even though SvcConfigEditor looked a bit different especially there's no Create button nor Logging tab.But I opened the app.config fille of the service and Under Diagnostic, I checked Default Message Logging, and under Message Logging I set to true both "LogEntireMessage" and LogMessagesAtTransportLevel". Saved the change and run the service and client .exe files, closed them and went back to the path of Log file which I selected under Diagnostic. But there's no .e2e file create ...Show All

• Visual Studio Team System Work Item Access control based on Work Item Type?

  We'd like to give our customers access to TFS for reading e.g. bug-information. Thus we would need a speciel security group that controls this access, e.g. a "Bug-readers"-group. However, what is needed is to define access to particular types of Work Items, namely only Work Items of type "Bug". We don't want our customers to be able to see Tasks or Requirements. How can an access control for Work Items be set up for specific Types or based on information in other properties of a Work Item regards, *Martin. Thanks, Jason. The Area-setting does the trick in my case. However, this reveals a difference in security access control for the Datawarehouse and the Work Item T ...Show All

• Visual Studio 2008 (Pre-release) Sizing content to Parent StackPanel

  Hi, I would like to know if it is possible to make content inside a StackPanel to automatically size itself to the size of the StackPanel. This is possible in a Grid, but I do not know how exactly to implement this with a StackPanel. Thank you, Jaco Thanks, but that does not have the desired effect. Maybe if I showed some code... TextBlock txt = new TextBlock (); Rectangle rect = new Rectangle (); TextBox box = new TextBox(); box.Visibility = Visibility.Hidden; Canvas can = new Canvas (); StackPanel panel = new StackPanel (); txt.Text = "This text can be change, so the size of the stackpanel will be affected" ; // TextBlock always sizes the Sta ...Show All
