Pause %WM_TIMER

[Cliff Nichols]

How do I go about pausing the %WM_TIMER???

All I can find is SetTimer and KillTimer, but nothing about pausing.

I have a partially working Timer that "Pauses" by killing the timer and recreating it when I am done with my paused amount of time (time unknown till runtime), but find myself in a catch 22.....of either stuck in a continuous loop, or runs fine the 1st time but only runs half-way through the second time.

I am out to demonstrate to the user how my program works, but at points where I wait for them to press a button, I need the timer to not fire until that function is complete.

Is there a pause? or do I have to set another flag to ignore the timer fired while I was off doing something else????

Not quite sure what you are doing, but there is no 'pause.' Usually timers are just killed, then recreated when needed again.

If you are in a loop, the problem is code structure, because your kill/set sequence is pretty much "SOP."

But you could (if you were ambitious)...

Use Waitable timer in its own thread (demo: Waitable Timer Object Demo June 2005)....

... and when the timer fires post a message to your main window.

When you want to disable it.... THREAD SUSPEND the thread with the timer object code and THREAD RESUME to re-enable.

It's a thought... but it sure sounds like overkill to me.

The problem you have here might be mis-application.... timers are used to wait for a time, not a user event such as clicking a button, or waiting for a function to complete.

To wait for a function to complete, run it from your GUI in a separate thead of execution as demo'd here in the demo I should have created years ago: GUI + Worker Thread + Abort Demo 11-24-07

Thanx MCM....
I thought about your Wait-able Timer object a few mins back and maybe that is the key....

Since this a add on to a full blown program....I am going to have to go build a mini-demo of my situation.

(and probably find another case of CNDS )

In a case such as this...I am sure its something that I am doing wrong....either by not understanding...or by seeing the same code for so long, that I can't see an obvious problem.

Just keep the timer running and toggle an entry flag (using a static variable or other method) when executing the task.

Very easy, and by far the simplest solution

Maybe you don't need to re-invent the wheel.... Wink

A vote for waitable timer

I have used the waitable timer with success. Worth the time investment to understand & implement.

(Thanks to MCM for his demos that flattened the learning curve. Or sharpened it? Whatever... )

He has helped me a lot more than he knows.
