    All COM methods are non exported. So you have to go regular COM way: register server, create coclass instance, query interface, etc.

    All of those things are explained in any tutorial or book on COM programming.

    I guess you didn't read my post.

    All of that information is explained in great detail in many tutorials and books. Having one of us to retype that same information here is not fair. Just do your research -- you have the Internet.

    I have to disappoint you. There's no way to learn something non-trivial (like COM) been having "a very limited time". Sorry.

    Again, there is a huge amount of source code available that shows how to load a COM DLL and call the functions using CoCreateInstance, QueryInterface, etc. Have you made any effort yourself to find and read this information?

    Again, it really isn't fair to ask anyone here to go through a full tutorial on how to call COM methods. It's no different than asking us to explain the C++ language and the rules. A forum isn't designed to be a teacher -- it's there just to answer questions in a quick and efficient manner.

    Just go to the Internet, search, and you will find ample amount of documentation that's out there. If it's so important for you to get this done, then you wouldn't waste time waiting for Igor, myself, or someone else to be your teacher. You have to be proactive and search for the vast number of tutorials that shows you not only how to use an ActiveX or COM control, but how to build one.

    An example:

    http://www.google.com/#sclient=psy&h...b94ef403c105f7

    If after you have your code set up, and you have a specific issue with the Active-X program, then you can ask questions.

    Regards,

    it seems that there is a big miss understand i didn't ask you to teach me any thing i was just show you the case to put me in the correct way when i posted last reply i tried to let you know the type of the dll as you said "if it is a com" and as i don't know its type so i posted the last reply

    i totaly agree with you that i must do my research but at first i must know for what i will do my research is it about calling com dll if it is a com dll
