Yes Andrew, you were right, it didn't work. I will try to ask for a VS2005 compiled library, but I have little hope that this is going to happen. It's a bank I am dealing with and the ".dll" is my access interface for Point-of-Service transactions.
Thanks for your answers. Regards, Eddie -----Original Message----- From: Discussion of advanced .NET topics.

My recollection is that the symbol mangling changed from 6.0 to 7.0. If it is a C++ Dll you probably want to try and get the third party to rebuild a version for VS2005 for you Andrew -----Original Message----- From: Discussion of advanced .NET topics.

Visual Studio is notoriously bad for supporting LIB files generated with a different Visual Studio version, especially LIBs for DLLs.
