Hi Guys,
I have been having this problem recently where I have a form with a
textbox and button, if in the button event I have the following:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Me.Cursor = Cursors.WaitCursor
Textbox1.text = Now.Tostring
System.Threading.Thread.Sleep(2000) ' 2 second wait
Me.Cursor = Cursors.Arrow
End Sub
If I click the button the mouse cursor changes to an hourglass,
updates the textbox with current time and after 2 seconds the mouse
cursor returns back to the arrow The problem lies that when u click
the mouse button repeatedly even though the mouse cursor changes to an
hourglass the button is still clickable furthermore u can type text in
the textbox.
Is this the default behaviour of .NET? Is this a bug? I have even
tried disabling form elements and changing the cursor of these form
elements to hourlgass with no success can someone please help thanks

This is the default behavior of Windows. Mouse and keyboard interaction and
other events have always been queued. Even in DOS there was a keyboard
buffer queueing the keyboard input.

Hi Armin,
I saw your answer, and please see my message about what I thought it was a
bug but you say normal behaviour.
Now I know that this behaviour is known, I did not know it, but I find it
weird, no user will understand it.
Thanks anyway
Cor A question like this has been yesterday also in this newsgroup
the answer is make the textbox1.enabled = false I think you mean button1.enabled = false, but, this wouldn't help also.
The mouse clicks will be processed after the button has been enabled again.

Thanks for all your replies guys, just afew follow up questions:
1) So if this is the default behaviour for windows in vb6 apps would
the same problem occur?
2) How do you get around the problem? Disabling a form element will
not help since after the event occurs the mouse messages continue so
how do you cancel them?
3) Can sample code be posted to solve this problem?

Put the work in a different thread. Your UI thread will stay responsive. In
this thread, I usually show a modal Form showing the current process and the
progress (if possible). The Form also contains a cancel button.

Hi Armin,
If you see the test I did in this newsgroup with my question if it is bug.
I could not get the unwised behaviour when I disabled the textbox instead of
making it read only.
I was thinking on that later, maybe you can try it.

Something like that (C#):

I thought I've already answered in the other thread. Now I looked again and
saw that my reply was still in the templates folder = not sent yet. I didn't
send it because I was unsure about the "message of your message". Well, I've
sent it now but it doesn't contain much, so.....

I'll have a look.
