I have used this code before to do something similar before...

If you go to: http://www.mvps.org/vb/ and look in the Samples area for
'Shell32.zip', it has a library with several methods to call and wait for
applications to shell, etc.

Hope that helps.

Subject: [OT]: Shelling in VB


Hi everyone,
Once again, I have a Visual Basic question and you are the most
knowledgeable group I know on this subject.

I'm trying to run an external program from a VB program (the external
program is actually XXCOPY, as mentioned on this list not long ago,
because I am using it for backing stuff up over a network). It is working
well except that I can't find a way to make it wait for the first process
to finish before spawning a new one (so, if I want to sequentially call
XXCOPY 10 times, I instead get 10 copies running simultaneously).

I could probaby do some kind of trick where I have XXCOP log it's output
to a file and then keep checking the file for the last line to be
written, but I thought that possibly VB would have a built-in way of
doing this (I'm currently using the SHELL command and that appears to not
have any option like this).

Thanks,

Sean
