There is a running application I did not write.
In order to automatize some processes, the application should think the user hit some keys.
So my program in VC++ 6 should "send keys" to the application.

As the application is quite low level, it may catch some interruptions to detect a keyboard input.

What is the way to simulate keyboard input in the application from my program?

What if the application catches directly the interruptions?

Thx (using vc++6 under XP)
