Executing external program - MDI?

[Gerald]

Hi,
After going through many tutorials suggested by the guys here etc I've finally got to a point where I feel comfortable with win32API albeit in C and not C++. The Forgers tutorial I found most useful. However, I'm a bit confused about calling another windows program, ( via say a button or menu item ), from within my main one. Do I go down the MDI, ( parent/child ), route or am I missing a concept?
Basically, I'm trying to call a simple windows utility from within my main program.
I do hope this is'nt a stupid question but any help would be appreciated as always.

Thank you.

Gerald.
