I have an old DLL written in Visual Studio 6 which I am calling from C# written in Visual Studio 2010. The DLL is not working properly and I want to debug into it. How can I do this? I have the source code project but cannot see how I can step into it.
Note: When I say “doesn’t work”, the call to the DLL succeeds and it gets a little way through the code in the DLL before failing, but I want to track down exactly where.
The technique of debugging a DLL is described here on MSDN. You’ll need to do this from Visual Studio 6 (i.e. the tool that developed the DLL) and so the terminology will have changed. But the principles remain the same.
