dll exception: int at memory location errors

[jeffpogo]

I am trying to use the dll from Pegasus Imaging Twain PRO.

I am able to call the dll functions and scan documents but I get the following error when I try to save the image file. (all I am doing is calling their functions and I see lots of exceptions: int at memory location 0x0a...)

Unhandled exception at 0x7c812afb in SwsScanning.exe: Microsoft C++ exception: _com_error at memory location 0x0013b8fc..

Is there a trick to working with non-Qt Windows DLL files?

Could the memory problems be a compiler or linker flag problem? or do these dll's usually work or do no work?

Thank you for your help!

Jeff.

I need to figure out how to catch the windows exceptions.

Thanks.
