Is there a way to get back the output of an executed program that is run by VB's SHELL funciton?  I could easily make the executed program store its results into an output file ie. "> output.txt" and just read in this file but i was hoping that the shell function would return back these results that were displayed on the stdout (the screen).  

The shelled program is a dos running program that just displays text on screen.

You can't. Your only option (with NT) would be to open a pipe and run your command sending the output to this pipe. This won't work generally though; redirected console output of MS-DOS apps is saved in a temporaray file and sent to the next program in the chain by using input redirection.

Shell returns a handle on the calling program. You can just check whether the program is still running but you can't get the output.

If you don't have the "Close on Exit" option set on your programs properties page the DOS  window will remain open until you click on the [X] even though the program itself has stopped running. This allows you to read the screen prior to closeout.
