I have a form which performs some asynchronous code. I want to display a
wait cursor when it starts, and hide the wait cursor when it has completed.
This part works fairly well, using:
this.TopLevelControl.Cursor = System.Windows.Forms.Cursors.WaitCursor;
I also want to prevent user interaction with the controls on my form while
the wait cursor is displayed, so that use events (except resize and cancel)
are blocked. What is the recommended way of doing this in .NET?
Thanks,
Aaron Queenan.

You can set the Enabled property of a control or even a form to false. This
will prevent any user interaction.

Unfortunately, it will also change the background colour to grey, does some
wierd colouring of ListView controls which have items in, and inconsistently
disables scrollbars depending upon where they are and who owns them. :-(
Is there any way I can disable the user interaction _without_ setting the
Enabled property to false?
Thanks,
Aaron.

Aaron,
You could override WndProc, and just toss out most of the messages that
come into the window. Of course, you would have a property that would turn
on and shut off this behavior. You will probably want to still handle
WM_PAINT messages, at the least.
Hope this helps.
