Hi John, Oh boy, what did I do? No, you can't add threads. That's VFP internal, some are used for the timer event, some for grids/browse.... VFP itself is a single-job language: You start one program and it runs til the end. That's it. If you call a subroutine, the main program stops until the subroutine is finished. Single job, single thread.
We do have a "Multithread" runtime library: vfp9T.dll (T as in Thread), which is especially useful for COM-Servers, which are called from several threads of a webserver. It solves some issues with memory usage (since not every Web-Session starts a new VFP), but also brings in new problems because those user-sessions aren't completely independent. What you may want to play with: ParallelFox on VFPX: https://github.com/VFPX/ParallelFox It is basically an extension to span new VFP tasks from within your main program (called "worker threads") to do subroutines without halting the main program. Coordinating those routines and getting notified about thier finish is the complicated part, and that's what this library does quite nicely. wOOdy -----Ursprüngliche Nachricht----- Von: ProFox [mailto:[email protected]] Im Auftrag von John Weller Gesendet: Mittwoch, 6.
