Checking events while in a loop

While running the following code:

Do While (err = 0)
err = CANPC_read_ac(param)
frmMonitor.StatusBar1.SimpleText = "No new Can event"
Loop

none of my events (cancel_click) etc work. The program is in a loop waiting for err to change from zero. Is there anyway of checking the "event list" so that my buttons still work?

I may be wrong but can't you put a DoEvents inside the loop? I haven't used it myself but I've seen it in code before. I believe that what it will do is check to see if there are any events waiting and it will do them.

Yup, this works a treat, Cheers!

How do you use DoEvent? The MSDN Library seemed a bit vauge to me.

Micah, from what I've seen, basically you just put:

DoEvents

in your code and what it will do is check to see if there are any events (like mouse clicks or keypresses) and it will run them and then come back to your code. I think. :-)

YES! That's beautiful. Cool, I'll play around with it.

DoEvents runs all the events saved up in the event list while your program was away doing much more interesting things.

In my case events were`nt getting handled at all because my program was in a Do While loop. Adding "DoEvents" in my loop cures this problem.

Thanks for the advice netsurfer. Cheers!

no problem, this forum is where I learned about it too :-)
