You can treat COM as protocol for writing the activeX components or Com DLL.

Thanks a lot, i got it but one thing is still ambiguous........then why do we need ActiveX controls when we have COM ? thanks in anticipation Azam

Hello Azam, Let take a example for understanding difference between COM DLL and ActiveX Control. if you are done some Windows Programming, you must have use CreateWindow()(which help in creating window) api, this api is just a function with no user interface but when you use BUTTON on the Dialog box it have UI to interact with it. same is difference betwwen COM DLL and ActiveX Control. COM Dll proviode you with backward functionality like CreateWindow and ACTIVE X Control provide you BOTH backward Functionality and UI (depend on your need) like BUTTON. Hope you somewhat grasp the difference between COM DLL and ActiveX Control
