ignoring mouse clicks

Currently, when my application needs to write/read to a
database, there is a time lag. In that time lag, a user
can click the same button multiple times causing my app
problems. I want to turn the mouse pointer arrow into an
hourglass and ignore mouse clicks until my app finishes
working. Most commercial apps I've looked at do this.
Is there an easy way to do this (ie. any built-in
controls in VS.NET or classes in MSDN)? Any suggestions
and/or code samples would be greatly appreciated. Thank
you for the reply.

A lot of times that behavior is because of single threading and the app is
simply waiting for the next line to complete. You could set the button's
enabled to false and then when the proc is done, set it back to true or wait
for whatever event to occur to tell it to be enabled.

You coudl do the similar thing by setting a bool and once the button is
clicked for the first time, set it to false. On the same click event, if
not myBool Exit Sub.
 
Mike,

Something along these lines:
-------------
Cursor = Cursors.WaitCursor;
// ... do processing
Cursor = Cursors.Arrow;
-------------

Is this what you were looking for?

Regards,
Alex

when using C#, you could use teh -= operator on the Click-event (and
+= to re-subscribe after the processing)
 
That is exactly what I am looking for. Just one thing,
after I turn the cursor into a wait cursor, is there a
way to disable all the controls (e.g buttons, textboxes)
so that I can't click on anything, or do I have to
disable each control individually. Again , thanks for
the reply.
 
this.Enabled = false;
