Hello,
Is there a way to stop the RUN command from flashing a DOS window across the VFP screen (the DOS process does not require any user interaction) or alternatively, if I use ShellExecute, how do I make the calling VFP program wait until the ShellExecute operation has completed?
 
To answer your first question, put [tt]/N[/tt] in the command. For example:

[tt]RUN /N "MyProg"[/tt]

But when you do that, VFP won't wait for the DOS program to finish or to exit. Control will return immediately to VFP.

Re ShellExecute(), there is no way for VFP to know whether it is still running or has finished executing, so control always returns to VFP immediately after the ShellExecute().

However, there is another way of achieving your goal:

Code:
oWSH = CREATEOBJECT("wscript.shell")
oWSH.Run("MyProg", 3, .T.)

The "3" means to run the target program maximised. The .T. will tell VFP to wait until the program closes or exits.

Keep in mind that you will need to pass the full path and filename of the target program, unless it is in the Windows path (which is not the VFP path).

Mike,
Thanks very much for your suggestion. I implemented the CREATEOBJECT code and it worked perfectly.
Thanks again.
