Waiting in a program

Hello

I need to allow the program to idle while in a loop to allow another
screen within the executable to be switched to.

DO WHILE TRUE
// some code including the exit

// wait state allowing control
ENDDO

If certain conditions are triggered I need to stall this loop and go to
another screen in the same application and do something there.

ApplicationExec(EXECWHILEEVENT) and Sleep() both don't work in this
instance.

Any ideas please?

Martin,

Have you considered when the condition is true and you need to start another
window to do it modally?

Regards,
Willie

The other task will not be a modal window, but will be another open
window in the application.

I am looking at a quick fix to a fatal embrace locking situation in a
number of places, quite a big rewrite on a saving routine to avoid it.

This is not a permanent fix, the rewrite is, this is just so the user
can change window and exit it while waiting for a lock.

Happens occasionally at 2 sites or so, but I may want the switchable
lock wait code for other uses.

How about

DO WHILE inkey(0.1) = 0
ENDDO
.... with your choice of redirector based on keystroke?

Is this program controlled or user controlled??

If user then it's really out of your control as windows will set focus to
whatever window/control is clicked.
I program control then in your loop
if condition_tested_for_is_true
// Abort what I'm doing in this loop
// Set focus to the other window
// Do whatever on that window and return here once it's done and
// hope like hell that the user didn't do something to these windows
// before I get back here
endif

How do you know that 'other' window will even be open??
Will/can it be minimised??
Do you expect to pass data into the 'other' window??

Why can't you have the current window do whatever it is you want done??

See my reply to Willie

It is so control can pass to another window in the application while
processing pauses in another.

Martin,

DoEvents() in your loop designed for this purpose. Basically it allows
multi-tasking while other events are working.
