Can someone tell me the difference between COM and DLL? It seems to me that COM is a specific type of DLL.


Thank you for any help.

Hi peterc, did you mean to post this in development? I'm not that much into development to know if those are development questions, but it sounds more to me like you are asking about different things....although, I could be wrong :D

Hi AcaCandy,

I believe my question belongs to Development since it is important to understand DLL and COM to develop applications. I don't find another forum which is appropriate for this question.

Thank you for asking,

Peter

Indeed your question is in the right forum. A DLL (Dynamic Link Library) is executable code packaged in a .DLL file, not part of the program that requires them. It could be simply a collection of much used functions that you want to share amongst programs or something more complex. COM (Component Object Model) is not a physical "thing" like a DLL, it is a protocol for communication of objects. COM compliant objects expose properties that allow other programs to access/query/modify them. COM is an evolution OLE.
