Hi,

I have a library(.lib) file which is designed in Visual Studio 2002(7.0) using MFC7.0. Now I need to link that library From Visual Studio 2003 (7.1) using MFC 7.1 and call functions from that library. While trying to link the library, I am getting this error: "Unable to open file : mfc70d.lib".This is understandable that the library refers the files of version 7.0. My question is: How can I link the library from VS 7.1 and call the functions. It would be a great help if anybody could tell me how can I do that?

Thanks in advance.

If you had the source code for that lib, the easiest way to go would be to rebuild it using the "newer" version of VS.

It depends - I can only assume that you don't have the source code for the library. You can try, if you are really desparate, the following:

Export object files from the lib file.
disassemble trying one of the tools from Fee Disassemblers[^] that seems to fit the requirements.

alter embedded library references, and assemble and rebuid your library.

Will it work? I haven't the faintest idea ...

Another approach would be to export the functionality from your VS2002 library as a dll with a flat c - not c++ api.

Best of luck

Here is something: http://www.parashift.com/c++-faq-lite/mixing-c-and-cpp.html
and: http://msdn.microsoft.com/en-us/library/a90k134d(v=vs.80).aspx

The c/c++ version of this project,http://site.icu-project.org/, provides a c api to functionality implemented in c++.
Good luck

Thanks for the link to the disassemblers! 5+
