• Visual Basic Missing Form [Design] Screen

  I have a serious problem that is causing me to lose weeks of development time. I removed a foreign key from an SQL database that was not needed. When I went back into a working VB project that was using this database, I received an error on the form [design] screen regarding a missing foreign key. From this point on I have been unable to "find" the form design screen within my project. It seems to have simply disappeared from my project. Is this a bug, or is the form designer hidden where I cannot see it ...Show All

  If I have an int like: int i = 1; and I have a string representing int i like: string name = "i"; is there a way I can turn the "i" into a variable name to access it's value Not really.

• Game Technologies: DirectX, XNA, XACT, etc. No shader syntax highlighting

  The readme file of the Dxsdk December update says: "HLSL syntax highlighting works properly in Visual Studio 2005 but the Direct3D 9 Shader Debugger is not currently supported. " Well, the syntax highlighting has never worked for me in VC++ 2005. I thought the Dxsdk December update would fix this ( I found another post here that said it would) but it didn't.

• Visual Studio MSDN 8 Installation on a server

  Hi all, Looking to setup MSDN on a server and have clients connect to a single install of the library (to save disc space) but can't seem to find any documentation on how I do this (or for VS 6 and 7 for that matter!) regards, Alex Hello, Unfortunately this feature is not available.  But, in VS2005 we've added Online Help integration, so you can get F1 & Search functionality without installing any docs locally. There is a "run from source" option in VS2003 & Quarterly MSDNs, but it doesn't allow multiple clients to connect to a single doc install.  It still requires part of the installation to occur on the client's mac ...Show All

• .NET Development Problems adding web reference

  Hi guys, I quite new to web services. I'm not quite sure if this is the place to post this but my problem involves a web service so here goes. I am using Visual Studio 2005 to create a windows service which will call some functions exposed by a web service. Now, my problem is that I can't add that web service as a web reference. Some background on the web service is that it is compiled in Delphi 2005. And it has a .dll extension, which is different from the books and web I've read which shows .asmx extensions.
