• Visual C# Does c# transaction include SQL After trigger?

  I performs a series of update/insert actions in with a c# transaction.  Some of the actions have AFTER trigger in the SQL database.  I have the following questions: 1. If one of the trigger fail, would it cause the transaction to rollback all actions 2. If one of the action fail, would the transaction rollback all trigger also Thanks  If you are talking about a SqlTransaction object then yes on all accounts.  SQL will basically make the changes temporarily to the tables and run the triggers as normal.  Only if no errors occur does it effectively save the changes to the underlying DB tables.  ...Show All

• Visual C# Using a C# dll in VB6

  Hi, I would like to know if it is possible to use a dll that has been created in C#, in Visual Basic 6.0. If so it would be great if you could let me know how I can make this possible. Thanks & Regards, Frenz Yep! it's possible... You just have to create your C# class and compile it to a dll, then use regasm.exe for assembly registration and typelib generation... regasm YourAssembly.dll /tlb:YourAssembly.tlb This command makes the appropriate registry entries and generates a typelib (.tlb) from the .NET assembly so that it can be referenced from VB 6 and just use the referenced library just as y ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Meshes intersection

  There is one method in DirectX API to try intersection between meshes . All functions I see are for mesh and ray combination. If not I'd like to know one good method. The problem with including generalized collision detection is that different games will need to emphasize/deemphasize different things.  For example, does the game take place indoor or outdoor   Is it a flight simulator, a shooter, a strategy, an RPG, an adventure, or a racing game   Each of these have different requirements from their collision detection library. The basic algorithms for collision detection are well known ...Show All

• Visual C# How to have my webcontrols come with images in them

  Hi people, I would like to create a webcontrol that has its own icons built into it (basically, the images go with the code as a single file). I thought that a resource file would do the trick but the compiler complains about converting system.drawing.bitmap to system.web.ui.webcontrol.image. Any suggestions/ideas Thank you very much! You can just add the images to your project and set the build action to embedded resource. A great blogpot of Drew you can find here: Deploying Images with Custom ASP.NET Controls . ...Show All
