Using DLL files

How can I find what functions and what pamameters are included in a DLL file?

If you can add a reference to the DLL, then it is COM and you will see that information in the Object Browser. If not, it is a "standard" DLL and function export names can be seen by using a GUI app like Depends.exe or console app like Link.exe. You will not see the numbers or names of parameters in either of these. This information should come from the author of the DLL.

Thank you ver much for your response in my question. I will follow your suggestions. :)
