Visual Basic&database, Launching a DOS program

Launching a DOS program

Author	Message
Sylvain Demart #1 / 3	Launching a DOS program I use the "shell" command to launch a scientific DOS program. This one creates different files, and I have to use its in the same sub when my program is finished. The problem is that the sub and the program continue to run in the same time so I can't exploit my files in the sub. So, how can I make the sub waiting for my program results ? Actually I use error management with a loop around an "open" command but it strongly decreases my program speed...

maxi #2 / 3	Launching a DOS program Maybe use a timer instead of the loop? Then just check for the file every 5 seconds or whatever time increment works best.

Joe Far #3 / 3	Launching a DOS program The MSDN has an articles that describe how to launch a program using Shell and then wait for it to complete. Search the MSDN (http://msdn.microsoft.com/vbasic/) looking for articles: Q171127 or Q212547 for VBA Q96844 or Q129796 for VB 16/32 bit Quote: > I use the "shell" command to launch a scientific DOS program.
