>hi,
>In fox 2.6, I remember some kind of timeout on a read statement. Does this still exist in VFP5?

>What I need:
>We have developed a reporting tool that's running on our network. We're constantly adding to it every day. When an enhancement is ready for production we have to fight to get everyone out of the .EXE to put the new one live.
>
>We'd like to have two EXEs, a shell, and the core application. Every ten seconds the core EXE checks if a file exists in a directory. (this was the timeout on read thing). If the file exists, the core EXE quits out to the shell EXE. The shell EXE does the same check for when the file disappears. When the file is gone, the shell EXE lets the user back into the core EXE.

>Does this sound like a doable thing?
>How do I make this polling process (is a do-while loop good enough)?
>Will modal forms in the core EXE pause the polling process?
>If so can I put the polling process in each modal form?
>Can a VFP5 EXE call another VFP5 EXE?

>Thanx,
