• Game Technologies: DirectX, XNA, XACT, etc. Problem uninstalling Beta 1

  Hi everyone, I've previously installed Game Studio Express Beta 1 and it's all worked fine. I'm having a problem uninstalling it though. I can't find the program entry for it in Add/Remove Programs. Can anyone please help me find a way to uninstall it as I can't find anything in the XNA folder that could help. You might try reinstalling Beta 1. That might clean up whatever got messed up the first time around so you can uninstall it. ...Show All

• SQL Server RS2005: ReportManager and Forms Authentication : The report server is not responding

  Hi, Sorry for the long post but I'll try to give a maximum of information. I've tried to implement Form Authentication for Reporting Services. Right now, just about everything works as I would hope for, i.e.: When I try to access http://<server>/ReportServer$SQLSERVER_2005 , I am redirected to the authentication form. When successfully authenticated, I can access the report I can display reports throught the ReportViewer Web control by passing the authentication cookie. Etc. (Note: My implementation of Form Authentication was inspired by http://www.devx.com/dotnet/Article/26759/0/page/1 which seems similar to Microsoft Sample) (The $SQLSERVER_2005 suffix is because SQL Server 2000 is also installed on the s ...Show All

• Visual C# Throw Exception gets unhandled error

  I am creating a multi-layered application using dlls' and want to throw any exception that occurs (and also create my own exceptions to throw) back to the originating code. When I try this though I get an error that the exception is unhandled. I am trying to handle it by just throwing it. This occurs at the first throw which is in class a catch clause. The following dll deals with database access. The code snippet is : class a{ public object ExecuteScalar( QueryBuilder QB){ object res = "" ; try { string sql = BuildSQL(QB); // connect to the database and run the query SqlCommand cmd = new SqlCommand (sql, DBConnections .SQLConn); DBConnections .SQLConn.Open(); res = cmd.ExecuteS ...Show All

• Software Development for Windows Vista Threading issue using windowless VMR9?

  Hi, I'm using a windows VMR9 (with a custom allocator/presenter) to play back a video file. I use a seperate thread to display the frames from the VMR9 onto some Direct3D geometry. The problem I have is that just occasionally the display thread will fail in a call to Device.StretchRectangle() when copying the surface generated by the VMR9 to my own surface. I suspect this may be a resource locking issue and the VMR9 is attempting to write to the surface at the same time I'm reading from it, but I'm not too sure, and I have created my device with the 'support multi-threading' flag. Is this likely, or is there something else I've failed to realise And if so, how do I lock the surface to prevent this problem from happening (Edit: oops, just ...Show All

• SQL Server SQL 2005 and ADO.NET 1.1 compatibility

  we have applications currently talking to a sql 2000 DB via ado.net 1.1. will we have any problems if we upgrade to sql 2005, will the app have to be modified. This will work fine together, although you cannot use the new features of SQL Server like query notification. But for plain data access that should fit your needs.

• Visual C# Making query in SQL Server - What is the best way?

  Hi i am making a web application using SQL Server 2005. i am trying to make all my query using stored procedure in database and just passing the parameter to the database.

• SQL Server SQL profiler not reading application names

  Hi guys, Im not really sure how complicated this is but we shall see. Im running a .exe compiled from 4GL which accesses the database. But when I run a trace on the database no application name is picked up. Does anyone know how SQL profiler finds the application name or what is required in the .exe file for SQL profiler to see the application name This would be a great help if anyone has any information. Many thanks, Querix There are a couple of ways that the name is populated. You'll often want to combine the application name with NT User Name and SQL User Name. The application reports the application name, and not all of them do. The name normally comes from the the connection string: server=My ...Show All

• SQL Server Excel as Frontend to SSAS 2005 Cube

  Hi, there, I am working on Excel as a front-end to a SSAS2005 cube. I intended to create a simple add-in that allows users to write back to the cube. Users will first retrieve data from the cube to pivot table and write back to the cube from the pivot table. I can find some sample source based on adodb and AS2000 but not adomd .net and SSAS2005. For the time being, information on SSAS2005 write-back from Excel seems very little. Not much references that I can refer to. Anyone can shed some light on this I would appreciate it if you can provide me some sample source in VBA using adomd .net or others that can demonstrate the write-back to a SSAS2005 cube. It would be great if the sample will be based on the AdventureWorksDW cube. Th ...Show All
