Not really a programming question, however! Make sure that the cable that you are using is a fully populated NULL modem cable.

You might find these guidelines [^] helpful if you're referring to Internet domains. The term 'domain' is rather loosely defined, primarily because Microsoft uses the word for nearly everything, and it's difficult to tell just what you're asking about. If you follow these rules for domain naming, though, I doubt that you'll go wrong regardless of the application. Will Build Nuclear Missile For Food - No Target Too Small

Hm...maybe you compiled your EXE with a different calling convention than your DLL? In VC6, check the following: Project -> Settings (or Alt+F7) -> C/C++ Tab -> Category: Code Generation -> Calling Convention You can also modify the calling convention of each function individually; i.e., try out all the combinations: EXPORT BOOL __stdcall Test1(BOOL b1) { return b1; } EXPORT BOOL __cdecl Test1(BOOL b1) { return b1; } EXPORT BOOL __fastcall Test1(BOOL b1) { return b1; } > When my application calls the Test1...() Anyway, is your EXE a VB application? Then you'll have to declare the exported function with __stdcall. It's the only calling convention known by VB. Regards, RK
