Visual Basic Run Time Errors

[Guest_imported]

Does anyone have experience with run time errors in Visual Basic? Specifically, run time error #48. I receive this when trying to execute a VB .exe that involves calling a DLL created with C++ source code.

When in debug mode, I cannot step through or over the point in the program where this error occurs. I have tried quite a few things with no success, such as copying the DLL to the directories where VB will search for it, hardcoding the pathway to the DLL, and placing the extension on the file name call. No success whatsoever. Please help!!

Thanks
JA

Have you tried the LoadLibrary API to debug the program? Take a look at

to find out more.

If this is an ordinary DLL (i.e. not a COM DLL), did you use __declspec(dllexport) to create your exported functions? If so, VB doesn't recognize those. You have to use a .DEF file for this. Annoying, but not that hard to fix.
