 debugging DLL problem


I have a VC++ Win32 DLL that has a method similar to the following -

extern "C" __declspec(dllexport) char* __stdcall

I also have a C# application that has the following -

static extern string beginEncode(StringBuilder inputFile, StringBuilder
outputFile, string GUID, int mplex);

However, when I attempt to debug the DLL by attaching the C# windows
application the debug output window will show

HEAP[RAWSATCTRL.exe]: Invalid Address specified to RtlFreeHeap( 00140000,
0016EBE8 )

Unhandled exception at 0x77f7f570 in RAWSATCTRL.exe: User breakpoint.

How can I debug the DLL? Should I be using another technique for accessing
the DLL?

The code in my DLL trys to create a callback event using the CreateEvent
method, will this work in a DLL? From what I can see I am passing the
parameters to the DLL correctly, just as I would with an EXE, but I am
getting a failure result when trying to pass a callback class to a method of
IWMReader->Open (Windows Media Format SDK).

Can anyone help?
