>>Hi Gang!
>>
>>I have 2 VFP exe's on this PC (call them VFP_a and VFP_b).
>>
>>They both are up and running. VFP_b is minimized to the taskbar. VFP_b had a timer running that is watching a table called "POS" for any new records to show up in it for processing, to be put into another table.
>>
>>When the records from VFP_a show up in "POS", the VFP_b sees them (through the timer) and restores on the screen to its normal size and processes the "POS" records, then ZAPs the "POS" table to restart again.
>>
>>What we would like for the VFP_a to do now, is to
>>
>>a) check to see if VFP_b is actually executting...
>>
>>b) press a "RESET" button on the VFP_b form....
>>
>>c) minimize the VFP_b executable when done to put it back on the taskbar.
>>
>>I am not allowed to modify VFP_b in any way, because the source code for that is now controlled in another developement house and location.

>b) I'm guessing that a "Reset" button in VFP_b can't be pressed while it's processing POS records. Or rather, maybe it can (and the keystroke will be buffered) but it's not always a good idea to do that. So, you may have to wait until it's finished processing (i.e. step c)). I haven't used it, but I think there's a SendKeys API function you can use to send keystrokes to another app as long as you can get a Windows handle to that app: http://www.foxite.com/archives/send-keystrokes-to-external-app-from-vfp-0000229059.htm

>c) Waiting for VFP_b to finish implies you need to set up a timer in your own app VFP_a and periodically check for some evidence that the other one has finished e.g. that the table has been ZAPped. I think there may be another API call that lets you change the minimized/maximized status of running apps, you could use that for this final step.

Thanks for the info!!
