FindWindow

InstallShield 2008 » InstallScript Language Reference

The FindWindow function provides a way for advanced developers to get a handle to a window by specifying its window class and window name. If you know the class and window name of an application, you can get its handle. You can then use that handle to send messages directly to the window.

Tip

To find the class and name of a window, run the Microsoft Spy.exe program.
