> Is it possible to use a DLL created with Borland in VC7.
If the DLL exports C functions, rather than C++ objects,
yes. Name mangling is not standardized, and every
vendor uses his own method.

I believe you will need to recreate the LIB file; Borland's
are not compatible with VC. Borland's IMPLIB utility
can convert a VC import library to Borland format, perhaps
it can do the reverse.
If not, you can build an import library for VC, using the
LIB utility, from a DEF file: you will need to make the
DEF file yourself.
