Yielding time

[Kevin Chandler]

Greetings to All,

I have a c# conversion app that does a lot of crunching and updates a status
window containing a RichText control. The updates to the control do not
appear until the job is done and the processor is freed up. I know in C++
you could pump some messages and the update would happen. I know in VB,
they had a call which would yield a minimum amount of time in order to
process events and update the display. What is available in C#?

Thanks in advance,
Kevin

You should start the work in another thread, leaving the UI thread for
UI events. Note that any status updates or whatever should occur in the
UI thread too - use Control.Invoke to easily achieve this.

Thanks!

It worked great. I should have known better. Suffering from a brain-fade.

If you don't want to go the multi-threaded route, you can still use DoEvents
as you did in VB. The equivalent C# call is Application.DoEvents().
