• Game Technologies: DirectX, XNA, XACT, etc. Some Questions About Making a DX10 App with a DX9 Fallback

  I'm working on a DX10 app with a DX9 fallback, and I have some questions. Right now, I simply have it setup so if DX10 initialization fails, it will use DX9 instead. Of course, this causes problems. While it may work in Vista, all other versions of Windows don't even have the DX10 DLLs, so the app simply doesn't even run long enough to know if DX10 failed. How can I have the app load the DX10 DLLs if it can, but if it can't, load the DX9 ones instead. Also, many functions in D3DX9 and D3DX10 go by the same name. Right now, whichever library I link first, it will call that version of it. For example, if I link d3dx9.lib and d3dx10.lib in that order, and call D3DXMatrixPerspectiveFovLH, it will be called using d3dx9_32.d ...Show All

  During my install I prompt the user for their username and password. I then try to verify this, but it requires elevated priviledges.

• .NET Development Using .NET Remoting within a CLR Trigger?

  Ok, forgive me if this is ridiculous question but is it possible to call a .NET Remoting method from inside a CLR Trigger My gut feeling is yes it's possible but there could potentially be a performance hit. Questions, comments...anyone....Ferris I don't think you can. And even if you can, it doesn't mean you should :). I believe that your problem is related to the ASP.NET cache invalidation when a table changes. So it might be helpful to investigate the techniques they used. Their purpose is the same, to call some .NET code from another process when something happens in the database. See http://msdn2.microsoft.com/en-us/library/ms178604.aspx ...Show All

• Visual C# Passing an inherited class as 'T' to a generic container.

  I'm having trouble finding out how to use a general purpose generic container I wrote as a member of another class which wants to hold any class type based on a common base class. The first set of code below shows 4 seperate classes, RNode is a generic class, TreeControl has an RNode<TreeItemBase> member, and a "Root" property to access it, TreeItemBase is a control (not really important to this), and TreeItemHeader is derived from TreeIItemBase...

  Is there any way in C++ to specify a custom path to implicitly link a dll I don't want to stay under the Windows Os dll path search. I would like to specify a path in my source or through the linker/compiler. That option is useful just for .lib files... I would like a similar option for .dll files. When i use my dlls i'm forced to put them together in the same direcoty or, while implicit link occurs, they won't find each other.
