what is the Advantage of ActiveX Dll over Active Exe ?

Answer Posted / guest

ACTIVEX DLL:
=============
An in-process component, or ActiveX DLL, runs in another
application?s process.
In-process components are used by applications or other in-
process components.
this allows you to wrap up common functionality (like an
ActiveX Exe).

ACTIVEX EXE:
=============
An out-of-process component, or ActiveX EXE, runs in its
own address space.
The client is usually an application running in another
process.The code running in an ActiveX Exe is running in a
separate process space. You would usually use this in N-
Tier programming.

An ActiveX EXE runs out of process while an ActiveX DLL
runs in the same process space as VB app.Also, and ActiveX
EXE can be run independent of your application if desired.
