Raise button click event from inherited form

I have a standard form I use. It inherits from Windows.Forms.F orm. I
usually add a Cancel button the form in the designer. I want to raise the
Cancel button's Click event when the user presses the escape key.

Public Class myStandardForm
Inherits Windows.Forms.F orm
Private WithEvents _btnCancel As Button

Private Sub _Load(ByVal sender As Object, ByVal e As EventArgs) Handles
MyBase.Load
MyBase.KeyPrevi ew = True
If Not IsNothing(MyBas e.CancelButton) Then
_btnCancel = MyBase.CancelBu tton
End If
End Sub

Protected Overrides Function ProcessCmdKey(B yRef msg As Message, ByVal
keyData As Keys) As Boolean
If keyData = Keys.Escape Then
' ******* here is where I would like to raise _btnCancel.Clic k
End if
End Function
End Class

Public Class myCustomForm
Inherits myStandardForm
Friend WithEvents btnCancel As System.Windows. Forms.Button
Me.CancelButton = Me.btnExit
Me.Controls.Add (Me.btnExit)

Private Sub btnExit_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles btnExit.Click
' ************ Sometimes I do special things here.
' ************ I want this code to execute as a result
' ************ of raising the Click event, which happens
' ************ as a result of pressing the Escape key
Me.Close()
End Sub
End Class

Take a look at the Button.PerformC lick method.

Ofcourse, you could also do something like this:

Protected Overrides Function ProcessCmdKey( _
ByRef msg As Message, _
ByVal keyData As Keys) As Boolean
If keyData = Keys.Escape Then
ClickProcedure( )
Me.Close()
End if
End Function

Private Sub btnExit_Click(B yVal sender As System.Object, _
ByVal e As System.EventArg s) Handles btnExit.Click
ClickProcedure( )
Me.Close()
End Sub

Private Sub ClickProcedure( )
' put your special code in here..
End Sub

Ofcourse, this is if you don't need to use the sender and e arguments of the
button click event.
There are probably other ways as well. I guess you can decide what suites
your app best.
hope that helps..

Correct me if I'm wrong, but if you set the CancelButton property of the
form to the button in question, I think pressing ESC will cause it to be
clicked.

I've been perusing a "real-life" application and notice that for instance, in a button's Click() event, they don't write the processing code. Instead, they raise an event like AddNewRecord and then put the coding that would have been in the click event in the AddNewRecord event handler. It seems TB throughout the app, so I'm guessing it's some sort of Best Practice. Anybody care to explain? -- PeteCresswell

I'm writing an application with custom skinned controls. I have a text editor form with a rich edit control. Because there's no toolbuttons in the skinned control set, I have to use normal ones for Bold/Italic/Underline etc. Because they're normal buttons, they grab focus from the rich edit. So to prevent losing the caret Ive used the Validating event to cancel focus loss. This works great. The application can be run in either terminal or...
