• Visual Studio November DSL toolkit: how to add commands to context menu?

  hi, I want to a add a command to the context menu. how can i do that with the new november toolkit I know that this is explained in a paper(customizing features in MS Tools for Domain Specific Languages (September 2005 CTP)) for  the semptember toolkit. i tried to map it to the november dsl version(since the structure of the projects changed) but it seems not to work. E.g there is no File " Designer\Diagram\PkgCmdID.cs " and " DesignerUI\Header Files\PkgCmdID.h " , it think was replaced by  " Designer\Shell\GeneratedCmd.cs " and " Designer\ctccomponents\GeneratedCmd.h ". So far I did  the following: Added a constant defini ...Show All

• Windows Search Technologies Search string?

  I get a little problem: all projects on our server are named YY-XXX (06-422, for example). When I search on 06-422, I can' find nothing but unrelated documents. I presume it has something to do with the '-' sign. looks like it plays it '06 but NOT 422'. Searching for "06-422" doesn't help neither. Is there a workaround TIA Hugues Hello Hugues, This one is interesting. Your line of reasoning makes perfect sense (the - acting as the 'NOT' operator). Strangely, I've been unable to replicate this problem on any of my test machines. I've been able to find files named 06-442, tr ...Show All

• Visual C# A problem about binary file source safe versioning

  Does anyone of you ever try to check in your binary files for versioning We have this habit since the day when we work on VB projects. Since COM versioning is very important, we have very clear habit to keep different versions of the DLLs. Now in .net, with VS.NET 2003, we realize there is a very strange behaviour which prevents binary files checking from working properly. Lets say, we have 3 projects: ClassLibrary1, ClassLibrary2, WindowsApplication1 -->: reference ClassLibrary2 --> ClassLibrary1 WindowsApplication1 --> ClassLibrary1, ClassLibrary2 When I have checked out all WindowsApplication1 binary files, while leaving ClassLib ...Show All

• Visual Basic System.DllNotFound Exception

  I'm migrating from VB 6.0 to VB.NET 2003. There is a particular file abc.dll that I'm not able to add reference to, though its a dll file. When I try to reference it, the error is 'This is a not a valid assembly or COM component. Only assemblies with extension 'dll' and COM components can be referenced. Please make sure the file is accesible, and that it is a valid assembly or COM component' How can I reference this file If this is not being seen as a COM component you likely need to do a P/Invoke against it. In your old VB6 project, did you have a few ‘define function’ statements that reference ...Show All
