Cetin,

If these are VFP apps you are launching, why not have the code either simply add the datetime() to _vfp.Caption or maybe a sequential number (each one could see how many others already exist and use the next number)

>*Main.App
>Get a launch request - ShellExecute another one as watcher (with some more params)
>Get a launch request - ShellExecute another one as watcher
>Get a launch request - ShellExecute another one as watcher
>
>Now watcher(s) has a problem. If requests are made with some split times they find the window right. If all request were done say from same routine, 3rd one might put up its window before 1st, leaving me no way to distinguish :(
