When you run an activeX control that is in a Dll. that control

is "inprocess" to the program that is using it. Thus access

is relatively fast. It also in general shares the threads of

the calling program (I believe).


When you are running an activeX control that is in an exe.

Then the control is out of process. This means that the program

that called the activeX control is sending messages to another

process(program) that is the activeX controls code. This is much

slower than a dll. However the exe has its own (possibly multiple)

threads to do its processing.
