Start external applications and check if they are still running

Hello,
I need to start several other Delphi executables from my main
application. They run independantly.
But when the main application is closed I need a way to check if there
are still any applications open that have been started from the main
application.
How can I do this?
I start the applications with Shellexecute.
Does this give me an id of the started application that I can check if
it's still running?
Thx,
Bernaert Dominique.

Dominique, you chose the wrong group for a question like this. It is not

about any 3rd party tools. Try borland.public.delphi.nativeapi.win32
instead.
I the meantime, Google for "delphi WinExecAndWait32". The source for that
will give you a hint on how to do what you want. Also have a look at the
help for the CreateProcess Win32 API function.

borland.public.delphi.nativeapi.win32 .

Or, better check the source of WinWget <www.{*word*104}shade.us/winwget/>--they have a nice unit for it and seems to be better and robust than any of the tricks mentioned above.

Or, use TJvCreateProcess component from JVCL.
