capturing and injecting click events into a win32 GUI with an external program

Question

_{Monday, September 15, 2008 5:05 PM}

I have a Windows GUI program written in C++ with VS2005 which outputs a standard win32 .exe  and I would like to capture click events and later inject those events into the .exe (preferably with an external program), to create a user-click-replay for automatically test GUI software.  I'm just starting so I appreciate and direction or hints.
Thank you
Patrick

What i understand is you want to get the mouse click from a compiled exe file .

You can use global hooks SetWindowHookEx()  to capture the mouse click and then send the mouse click back to the application by obtaining a handle to the application window .

You can inject a code or a dll in to your running application  and check the messages send to
the application and can send mouse click by using SendMessage( )

A very good article how to inject code

Note : If you have multiple instance of your application running on the same computer you will need to check if you are sending message to right application .
