    Wayne, doing a bare message loop in a SUB like that can have assorted
    undesireable side-effects -- don't, unless you're sure you know what
    you're up to! I'd use LOCAL instead of STATIC there, BTW.

    John, good idea, but SLEEP is only available in the 32-bit world.

    Would a simple SLEEP 0 perform the trick?

    Code:
    SUB DoEvents
        STATIC Msg AS tagMsg
        IF PeekMessage(Msg, %NULL, 0, 0, %PM_REMOVE) THEN
            TranslateMessage Msg
            DispatchMessage Msg
        END IF
    END SUB
    One of the many snippets in my pbfuncs directory , not sure who wrote that one though

    Oh, didn't see the "PB 2.0".

    If you're thinking of a VB-style DoEvents, that's not something you can mimic
    readily. VB's design is inside-out with respect to what VB is actually doing.
    Essentially, a VB DoEvents is releasing control back to VB's hidden message
    loop. In PowerBASIC, you have direct control over the message loop (if any),
    so there is no point in a "DoEvents" as such. You just need to break up your
    processing during the message loop so as to avoid taking up too much time in
    any one cycle.

    If your program does not include a message loop, perhaps the Windows API call
    Yield is what you want. See your WINAPI.INC include file.

    I suspect Sven has 32-bit PB/DLL in mind, which is a somewhat different animal.

    You should use the search engine of this Forum.
    You'll find a lot of examples for DoEvents

    started a topic DoEvents

    DoEvents

    Is there a way to perform a DoEvents call in PB? I am using PB2.0
    and I need to return control to the system while a routine is running.
