There is really no sure way, the only thing you can do is make sure it has
the focus.
I don't know who you are trying to send the keys to, but I assume you have
thought about some obvious stuff:
If edit control then use SetWindowText.

Now, if I use SendInput...
How do I make sure that the HWND that want gets the keystrokes?

If I wanted to send Key commands to another app what would be the most
correct way? SendInput? or would PostMessage be better?

Also, if I do a post message how would I create the wparam and the
lparam?
I tried this and it didn't seem to work.

wparam = 84;
lparam = 0;
winErr=::PostMessage( theHWND, WM_KEYUP, wparam = 84, lparam );

TIA
