• .NET Development Scenarios for running 32-bit dll's (WOW64) from a 64-bit (x64) host process?

  One way to make a .NET application using a 32-bit DLL is to compile it with a \platform=x86 directive. But this naturally degrades the host application to also be a WOWing application in the 64-bit system. Is it possible to wrap such 32-bit dll's for example in a .NET console compiled with \platform=x86 and then execute this from the host process application using for example ShellExecute (ShellAndWait) and letting the host process application be a true x64 app What scenarios is available Regards Peder Peder: As you point out you can not use binaries of mix matched bitness. Ie. Can not use 32 ...Show All

• Visual Studio Team System Branching is Broken - Severe SQL Error

  About two weeks ago I was able to successfully create a feature branch off of our Main\Src directory.  Last night I tried to help a co-worker create a different feature branch off of Main\Src.  We tried from the VS 2005 UI and via the command line with no luck.  Both ran for 15 minutes without completing.  Finally we left the command line branch going all night and when we got back in this morning the following error message was displayed: C:\Foo\Branches\Feature>tf branch $/Foo/Main/Src $/Foo/Branches/Feature/XYZZY A database error occurred (SQL error 0) ---> A severe error occurred on the current command.

  Are there any examples available of how to use the TypedDataSetGenerator class in the System.Data.Design namespace to programmatically create Typed DataSets Thanks Hi Wn, This is actually an internal class we use to generate Typed DataSets, and their associated TableAdapters based on the Typed DataSet Designer.  In order to maintain backwards compat for users that may be using the old generator, System.Data.TypedDataSetGenerator we moved this to a new namespace, System.Data.Design.

  Hello everyone, I'm currently working on a project (this is my first real program in C#) and I'm a little stuck on this part of it.  To keep it short, the program accepts input from the user (obviously) and that information is put into a dataset in memory.  The user can then save the information to an XML file.  This XML file serves 2 purposes (to save the information and to retrieve the information).  The XML file can be sent out my test web server where I'll have a small asp.net page that can display the contents of the file, or you can use the program to open the XML file back into a dataset.  Here's the proble.&n ...Show All
