Please be more specific.

The answer is a lot AND no differance at all.

You can use an ActiveX EXE as COM object.

Thanks VS

Here are doubts to clear.
As for as my knowledge is concern an activex control is nothing but like our textbox combo box etc. all controls where we can use in our applications. we can develop our own controls as we wish.

Then what is COM, MTS eExactly where do we use.

Thanks in advance

Hmm, sorry i'm not going to explain that. That's a bit too much for me. I have to do some work to.

here are some linkies:
http://www.microsoft.com/com/
look under features and you'll find links to:
MTS
http://www.microsoft.com/com/tech/mts.asp
COM
http://www.microsoft.com/com/tech/com.asp
DCOM
http://www.microsoft.com/com/tech/dcom.asp
COM+ (com for win 2000 and some more...)
http://www.microsoft.com/com/tech/complus.asp

Also look under resources at http://www.microsoft.com/com/

If you're just starting with VB don't get overwhelmed. It's touch but hey you've gotto learn somewhere. Also try the MSDN cd's.

There is NO difference between ActiveX and COM. Only people who mix up marketing with the actual technology view ActiveX and COM as different. They are the same technology. An ActiveX EXE _IS_ a COM object and nothing else. An Active X DLL _IS_ a COM object and nothing else. MTS(now called COM+) is a COM object itself that acts a host wrapper for other COM objects(follow the links in the above post for more info on that). So if someone asks, which do you know better, COM or ActiveX? answer, "What a stupid question, they are the same technology".

Its good to see I'm not that only one that has read some of Dan Appleman's books. I agree with pvb, the name, that is the only difference.

And it used to be called OLE...

ActiveX is a third generation of OLE
