• Visual C# Assigning By Reference

  Quick question, in this code fragment From my own experiance; though I'm now one for 'rtfm', I have found that Connection.Details = Conn.Details passes a copy whereas Connection = Conn passes a reference. I cannot explain why and it has lead me to start reading books for begineers again. Hell! I've always picked up new tricks, in every language, whenever I go back to basics anyway. ...Show All

• Silverlight (formerly WPF/E) "The WPF/E Installed on your system is no longer valid..."

  I just started getting this message on all my "WPF/E" pages but there isn't a new build of the WPF/E runtime. Something we should know or is there just a timeout bomb The exact message is: "The WPF/E Installed on your system is no longer valid. Please go to Microsoft's web-site for the latest version." Freinds, Earlier today, you may have noticed your “WPF/E” December Community Technology Preview (CTP) control expired. No worries though- we’ve just posted the February CTP for Windows and Mac to Microsoft's download center and updated the samples on the Channel 9 Playground to work with the new CTP. Note that to get your samples working with the February CTP, you’ll need to change out the a ...Show All

• SQL Server Calling SqlDependency.Stop() in class destructor

  Hey guys, Have you ever tried to call the SqlDependency.Stop() method in a class destructor (C#) It seems like the finalization process hangs after the call to the SqlDependency.Stop() method (for example the assignment after the SqlDependency.Stop() method call is never executed). ~Program() { if (!_finalized) { SqlDependency .Stop(NocConnectionString); _finalized = false ; } } I tried to use the ADO.NET 2.0 tracing, and it shows that the SqlCommand.Cancel() method call throws an exception during finalization, but it’s not possible to intercept it. Do you have any clue about it or have you ever experinced the same problem Regards, ...Show All

• .NET Development Passing credentials

  Hi! I'm making a webservice that should be called by a webservice client at a customer's location. I use Windows Basic Authentication and SSL to authenticate the client.

How will the credentials be sent to the server In the soapheader to the webservice Or in the https header Can somebody explain this to me, I need to know because the customer do not know how to pass the credentials to our webservice.

• Game Technologies: DirectX, XNA, XACT, etc. Color Banding

  I am getting color banding issues when viewing my project on my Xbox 360. The textures look perfect when the app is ran on windows, using the same XNA source just in a different project. But when I display the textures on an Xbox 360, I get serious color banding. These issues are most pronounced when my Xbox is set to output at 720p or higher resolutions, but the color banding is still there even if the Xbox is set to 480p. The following code is what I am using to setup my 'prefered' values for my graphics device. If you got any idea what could be causing this, I would appreciate the input. graphics.IsFullScreen = true ; graphics.PreferredBackBufferFormat = graphics.GraphicsDevice.DisplayMode.Format; graphics.PreferredBackBufferH ...Show All

• SQL Server Questioning my approach to generating aggregations

  Hi, I'm using the aggregation wizard to build my aggregations. Due to my not having much data in my development environment the wizard acutally produces zero aggreagtions. I know that there will be much more data in the production environment although I don't know how much. Hence, I go into the 'Specify Object Counts' page and set the number of records in my fact table to an arbitrarily large number (usually 1000000) and this results in some aggregations getting produced by the wizard. The issue I have with this is that perhaps I am producing too too MANY aggregations. Other than the obvious issues of: Increased disk usage Increased processing time is there any other issues around building too many aggregations Any ...Show All

• SQL Server SQL Server Express and Access 2003

  I recently started developing a new Access project for a client, and decided to try out Access 2003 with SQL Express 2005. Everything was going fine until I tried to modify a table from within Access. I got an error message that SQL Express is incompatible with Access 2003, and it suggested I go to the Microsoft website and search for a patch/upgrade to solve this. I tried to ignore it, and it started warning me that none of my table edits would be saved. I looked around, but I can't find anything about this. Is this true Is there a patch to fix this I didn't see Joel's earlier post, that's the danger of posting additional questions into a thread that is marked Answered. Yes, Access 2007 has ...Show All
