How do use SendMessage to write into another app's window.

I have a script that I've used to write text into the window of another application.  By using the FindWindow and FindWidowEx api funciton calls, I was able to get that window's handle and then use the SendMesage function to actually write into it.  I want to do the same thing but write to a window of another application.  The problem I'm having is that I don't know the window hierarchy of this app so don't know which window this is a child of.  Is there any way to determine all of the children of a particular window and how to I access the handle of each?

Thanks!

If you have Visual Studio then there is a free tool that came with it called Spy++ that you can use to view the window structure.

If you don't have Visual Studio then try out the free WinSpector:

(I've used it before without any problems.)
