Thanks for your response.

I didn't make my question clear. I'm not really good with "include" files.

The variable that is not being found (cnErr_CANNOT_FIND_DLL_ENTRY) is defined in the include file SFErrors.h. Nowhere up the calling chain of programs does the cstr "sferrors" appear. I'm assuming that it should appear someplace up the calling chain in an include statement, like so: "#include SFErrors.h".

Is this not correct?

Thanks,
Dick
