With Delphi 2 'up you can create Windows 32 DLL's. The keyword is "Library" instead of "Program" in the first line. http://bsn.ch/tp-links has a lot of information about Pascal and Delphi programming. In the compiler chapter you find other compilers too. :-) -- Franz Glaser, Glasau 3, A-4191 Vorderweissenbach Austria +43-7219-7035-0 Muehlviertler Elektronik Glaser.

gabrie #4 / 5	Dll Windows 9x Hi! Well, I haven't used Pascal for many years, but here are some thoughts, which could help: - code the whole path and filename (with extension) in your declare statement - watch for spelling errors (sounds incredible, but it can happen:-) - In the programming world, there is a topic named "calling conventions". It's about how parameters are passed to procedures. Fact is that Pascal and C use different calling conventions. I have no idea how Basic passes parameters to subs, but maybe it is worth digging in the docu to find out if there isn't any incompatibility there. Maybe VB finds the file, but doesn't recognize the format - we all have seen stupid error messages by now :-) Hope it helps.

Chui Te #5 / 5	Dll Windows 9x I believe VB uses Pascal conventions. Watch out if you are passing arrays. VB arrays are mean stuff. Have a look around in the VB CD, there is an article on how to implement calls properly. Best approach is to get it working then wrap the calls up so that they look like ordinary VB functions. DLL not found ... place the dll file in C:\windows, or C:\windows\system or application path.
