Debugging Visual C++ DLL used with Matlab

In the past (version 2006) I've been able to debug a Visual C DLL, which I'm calling from Matlab, by starting Matlab.exe from the Visual C environment. Matlab.exe then loads the DLL, and I can set breakpoints in the DLL functions to debug my code. With the new 2010 and 2011 versions, Matlab.exe stops running before Matlab appears, so the Visual C debugger thinks it has finished. Is there another method of connecting to Matlab so that a DLL can be debugged? Thanks for any ideas.

I am assuming you are using loadlibrary!

If that's the case, then you can load your VS project (that created the C/C++ DLL) and load the DLL in MATLAB using the loadlibrary function.

At this stage you should Attach to MATLAb process using Tools->Attach To Process in VS.

You should now be able to set breakpoints in the C++ code and calllib calls from MATLAB should trigger the same!
