Hi,
I have an case as the following:

I have 2 standard EXE - Management System and Task Schedule Program. Both of them may call the same module (does something with Internet ---ModuleA). This moduleA may be executed once user click on a button in management system, or fulfil the condition set in task schedule program (time to run automatically).
Again, user may need the moduleA to be run at system startup.

What should I compile this moduleA to be, DLL, COM EXE or standard EXE?
IF I choise DLL/COM EXE, how could I put the path of this module in windows registry in order to be run at startup? Again, pls advise is eith EXE or DLL. thank.

IF I choise Standard EXE, How could I control the module in management system and task schdule program?

Pls tell me if you need any extra information.

Thank you very much!
