I found the problem, I had the VTune plugin installed in my VS install, when I removed it, I was able to debug ok. My guess is that the VTune plugin somehow messed up the pdb generation.

I posted this in the VS forum, but I guess its more specific to C++... I'm using VS.NET 2005 and building a large application with about 100 projects. There is one project in the solution that compiles to a DLL that I need to debug. (i.e. break, and step into the code) However I can't. In the modules tab of the IDE, it says that no symbols have been loaded for that module. I know the pdb is being generated though, has the same filename as my dll, and is being generated in the same directory as the dll. The timestamps match as well, and I'm building the debug configuration. When I right click on the module in the modules tab and goto "Load Symbols" and point it to my pdb it says that "The symbol file xyz.pdb does not match the module" What could possibly be going wrong?

You could try libxml. It can save/load XML files. http://en.wikipedia.org/wiki/Libxml2.

I'd rather just do the initialization once like you suggest, but the code I'm working on is a module to be shared among different client apps, so I can't be sure a priori if the client is already using GDI+. Thanks for the reply,

Thank you so much for checking this out!

Not much relevant to my question. http://msdn2.microsoft.com/en-us/library/ms534077.aspx

I've got a class that wraps GDI+. In the constructor I call GdiplusStartup, and in the destructor I call GdiplusShutdown. This could result in multiple startup & shutdown calls. (And possibly several startup calls before any shutdown calls) Is it safe to make these calls multiple times?
