• Visual Studio Express Editions Q: What is the modules

  hi, i'm new and i want to know what is hte differece between classes and modules , and when to use modules, thx Hi shak, The purpose of a module is to contain subroutines or Functions and to declare Variables or Arrays with the Public Command.  Modules have no visible properties and have no events because they have no controls.  Subs within the module are made available to your entire program (global) as opposed to local to a partuclar form or even more local to a particular procedure. The 'Visual Baic 2005 Express Edition for Dummies by Richard Mansfield is a great book for beginners.  It had most of th ...Show All

• SQL Server Database connection and local temp tables

  We have a C# process that opens a database connection, creates and populates a global temp table, manipulates the data in it and then renders a SQL report to display the data in the temp table. However, to avoid concurrency issues, we want to switch to a local temp table so that it is only available to the connection opened by the C# process. Unfortunately, when we try to render the report, the temp table will not be visible to the report server. One possibility is to call a stored procedure from the report that creates and manipulates the temp table itself, however this is not a viable option for us. All data processing must ...Show All

• Visual Studio Uninstalling Add-ins - removing toolbars

  Hi all, I have an addin for VS.NET which I've recently altered to work with vs2005.  I'm having an issue with uninstallation though.  When my uninstaller runs, it runs 'devenv /setup' to remove the toolbars for each of the Visual Studio versions installed.  This works (albeit with ugly consequences) on VS2003, but on 2005 my add-in's toolbar and commands are still present. Some searching around yielded the /resetaddin command, which kinda works.  It removes all the toolbar buttons, but not the toolbar itself.  Also, annoyingly, it fires up a whole new copy of vs2005 which then stays open - not an ideal thing to happe ...Show All

I did some debugging and it the error was that the vertex shader was not set correctly. I looked into the assembly with reflector and it seems that there is a bug in Device.set_VertexShader. It calls the function with the offset 0xc4 in the vtable of IDirect3DDevice9, but the index for SetVertexShader is 0x170. ...Show All
