How to Prevent the Click Event when a Button is Clicked

[Charles Law]

When I click a button I don't want the click event to fire. Is this
possible?

In fact, what I would really like is to be able to intercept the click
event, perform some action, and then prevent the click from passing through
to the button.

Any help or suggestions much appreciated.

Charles

Thanks Mick. It makes sense to avoid the interop if it is not necessary, so
I will use your suggestion.

Hi Charles

This method does not improve on Herfrieds, it just does away with InterOp.
The Class will look as follows:

\\\
Public Class UserControl1
Inherits UserControl

Private Const WS_EX_TRANSPARE NT As Int32 = &H20

Public Sub New()
SetStyle(Contro lStyles.Support sTransparentBac kColor, True)
Me.BackColor = Color.Transpare nt
End Sub

Protected Overrides ReadOnly Property CreateParams() As CreateParams
Get
Dim cp As CreateParams = MyBase.CreatePa rams
cp.ExStyle = cp.ExStyle Or WS_EX_TRANSPARE NT
Return cp
End Get
End Property

Protected Overrides Sub OnPaintBackgrou nd(ByVal pevent As
PaintEventArgs)
'
End Sub

End Class

Hi Mick

Which bit does this replace, or does it replace it all?

Mick (& Herfried),
That's a keeper! I knew it was relatively easy, I just could not figure out
the words.

Hopefully I will remember where I kept it, the next time someone asks ;-)

No need for Interop.

Protected Overrides ReadOnly Property CreateParams() As CreateParams
Get
Dim cp As CreateParams = MyBase.CreatePa rams
cp.ExStyle = cp.ExStyle Or WS_EX_TRANSPARE NT
Return cp
End Get
End Property

It's a good solution for this problem, however if you want to draw in the
window so as to make some parts Opaque or Semi Transparent, then you'll find
that there is a problem with zOrder painting, which is why I usually create
Shaped controls.

I have done something similar with a combo box that I wanted to extend.
It is pretty easy to search and replace the variable declaration and
instance instantiation lines in the code. You could add a property like
Clickable with a default value of false, etc, and then when you want to
make all your buttons unclickable cycle through them and set their
Clickable property to false. It didn't end up being too bad for my
case.

Hi Michael

I have settled on the idea from Herfried. Putting a transparent window in
front of my control does the trick. It is even easier as all my controls
inherit from my base control, so I only have to implement it in the base
class for it to work.

Thanks again.
