Ignoring events

[nemaroller]

I have some dynamically created forms...

problem is (during test I did this), if you keep blindly clicking you sometimes BOUNCE - click (best way to describe it), so the mouse fires another event before the button is actually created, resulting in some errors in my program since the button contains data necessary to move on....

So how do I tell my application to throw any click events out the window until its ready to receive them?

Can you just set a form level variable (blnAcceptClick). Set it to false when you want to ignore clicks, and set to True when you want to accept them. Then in you click event handler you would test the blnAcceptClick and if false then Exit Sub - otherwise proceed.

Hope that helps.

Are you using WithEvents as part of your dynamic creation. If so, maybe you should consider using AddHandler to manually link events and not AddHandler for the click events until you are ready.

I was using AddHandler....

and I moved it into the Form Activated event... same problem.

Seems like either the event is firing twice from the old form...

Anyway its really irking me because it never happens when I try it in debug mode... (i'm attributing that to perhaps the program is running slower, although I can't physically tell the difference in speed)...

Unzip the following project.... http://www.sofa.com/dc.zip

Open the unzip folder...

execute the DinesenBravo shortcut first....

Then run the WindowsApplicatino13 shortcut....

Hit Start... New Sale .... (any sales rep)... any customer... (hit OK)...

When you get to the invoice screen... hit New Item
Click on the Jaymar button as fast as you can.... (clickin in the same spot)...

After the error occurs... do it again but this time at normal speed... it works...

When I click the Jaymar button, it goes directly to another screen etrememly fast. You cant click on Jaymar fast enough. Not humanly possible.

Oh just keep trying... you'll get it

No, its not a serious flaw... but it can happen... and no it doesn't crash the application... and the user could just try again... but it just irks me it exists...

[Cander]

No really. It is not possible to click Jaymar more than once on my system in a row. It is too fast. Like I said, no human could do it.

Maybe configure your mouse so that the right or left button acts as a double click. Then try it.

[nemaroller]

Can anyone else duplicate this behavior or is it just my Dell Optiplex?

[Cander]

Why not in the click event, go ahead and disable the image button, or something like that as the first line of code in the event?

[nemaroller]

Cander, yes when you click the button it goes to the next screen, but that's ok, because then you begin to replicate the behavior... keep clickin at the same spot.... and you'll go threw 2 more screens before you hit an error...

How about

If Sender Is btnFoo Then
    MessageBox.Show("Boing")
End If
