You need a "run process and wait" capability. Take a look at Ed Rauh's API_APPRUN class file#9477, which can do this for you.

>I have an app in VFP which does a call out to the Winzip Command Line to backup some files. Pseudo code as follows:
>
>Sele Fil
>Goto top
>Do while not eof()
> WZZIP a*.* MyUniqueName && This is WinZip Command Line
> Copy MyUniqename to Network Drive
>
> Sele Fil
> SkiP
>Enddo

>The problem I have is that control is returned immediately to the Copy caommand, before the Winzip is finished.
>Also, the way Winzip works, the MyUniqueName.zip is actually created on disk at the start of the zip, so I cant test on the existence of the file or not.

>I have used a Loop which just waits 1o minutes, but some zips will only take 1 minute and others may take 12 mins.

>Any ideas on this appreciated.
