Bring Another Program To The Front

Hi,

Building a program that you can type text into then press the "copy" and that button then brings for example notepad to the front and pastes the text in.

I have mastered opening notepad fine and bringing notepad to the top but i'm struggling with opening any other program other than notepad.

The coding I'm using to bring the note window to the front is: (without all the keypresses etc)

'AppActivate("notepad")

Yet is I tried to bring say for example word or internet explorer it doesn't work regardless if i'm typing the program name, location, process name.

Any ideas?
