How to handle all KeyPress events in a form?
I know how to create an event handler for keypress events only when they are with respect to an object in the form itself, like a button or a textbox, etc.
How would I create one for the form itself and disable ALL the default handlers, like tab, return, arrow keys etc?
I've tried adding the handler for:
AddHandler Form1.KeyPress
AddHandler Me.KeyPress
AddHandler MyBase.KeyPress
all without sucess, which just shows how lost I am on this topic and would appreciate any help anyone has to offer. Thanks.

The same KeyPreview for a form exists in VB.NET 2002 check that.

I'm still not getting how to fix it.
I have a single form in the program, Form1
In the load section I put:
Private Sub Form1_Load(ByVal sender ...
Me.KeyPreview = True
...
End Sub
Then try:
Private Sub Form1_KeyPress(ByVal sender As System.Object, ByVal e As KeyPressEventArgs) Handles MyBase.KeyPress
Label1.Text = e.KeyChar
e.Handled = True
End Sub
But it doesn't catch any of the key presses. They system still does, tabs around the buttons in the form etc. The MyBase part has to be wrong on my part, there is no option for Form1.KeyPress only options for the various buttons and MyBase, thats it. If I replace MyBase with say TextBox1 it works great. How can I achieve this same functionality for the entire form?
Is there a way to effectivly pull off: Handles Form1.KeyPress?
Thanks,
Craig

Try the following:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.KeyPreview = True
End Sub
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPr essEventAr gs) Handles MyBase.KeyPress
Label1.Text = e.KeyChar
e.Handled = True
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.KeyPreview = True
End Sub
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPr
Label1.Text = e.KeyChar
e.Handled = True
End Sub

Did you try keyDown?
Did you try keyDown?
ASKER
Yes I have tried KeyDown and KeyPress with the same results. Even with the KeyPreview = True something is intercepting default key moves, like arrows, tabs, space etc. But when something like a text box has focus in the form then the MyBase does catch the key presses.
Any thoughts?

Actually the MyBase catches all the KeyDown events save for the special keys that I need actually. I dont need to focus any buttons etc and i can catch what keys are being pressed save for:
Arrow Keys, Tabs, Space, Enter and some others I'm sure ive missed.
How to catch those too?
