calendar control

[Dave]

I have a calendar control that has runs a longish bit of code in the
ValueChanged event.

How do I get the control to repaint before running the code.

At the moment the calendar month view stays active while the code is
running.

Thanks in advance

You can either call Application.DoEvents or execute your code on a
background thread. I recommend the latter approach.

Hi Dave,

What you require is asynchronous processing. You'll have to run the time-consuming code in another thread to free the UI thread.
You'll want to start a "background" process and handle an event when the process completes. You might need to disable (set
Enabled=false) certain UI components before running code on another thread and returning so that while your code is working in the
background your end-users won't be able to change their state. For instance, while processing the ValueChanged event for the
Calendar, you'll probably want the Calendar to be disabled until the process completes; however, you'll want the entire application
responsive to user interaction, including the painting of the calendar control, which is accomplished by freeing the UI thread and
running the time-consuming code in a background process as I suggested.

Check out the BackgroundWorker class.

Hi Dave,
