Very possible.
Either:
1. Compile your C++ code into a DLL, or other linkable binary.  You can then use Declare statements to call the exported functions in your DLL.
2. Compile a C++ module into VB during the compile process.  I haven't done this myself, but I know it is possible.

Yes I imagine it's possible... just extremely difficult. I recall Turbo C++ was Borland's old 16 bit compiler. It may be able to generate 16-bit DLLs, but I seem to recall back in those dark Win 3.1 days that 16 bit DLL programming is rather awkward since data segment DS will probably not equal the stack segment SS (get an old copy of Charles Petzold's "Programming Windows 3.1" for clarification on this). It won't be as simple as just changing a couple of compiler switches.

Although COM is a binary standard I wouldn't want to even consider recompiling a 16 bit C++ module under TC to be COM compliant. Scary stuff...
