Keydown event problem

[win]

when the cursor is in a textbox, only coding in the keydown event of the
textbox triggered, the coding in the keydown event of the form does not
triggered!
Problem: I need to change a VB6 program to .Net. It uses function key(e.g.
F12) to close the form, now i need to write the coding in the keydown event
of all controls form.

Can anyone help me?
Thanks a lot.

Hi Win,

You need to set the KeyPreview property of the form to true, which
indicates that the form will receive key events before the event is passed
to the control that has focus.

Hope this helps.
If you have any question, please feel free to let me know.

Hi,
If you want to close the form with a keypress having with several
controls on the form:
First set "KeyPreview" value to "true" in form properties.
Then simpy associate keydown event with form:

'Here is key for F12, you can change it whatever you want:

Private Sub Form1_keydown(ByVal sender As System.Object, ByVal e As
System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
If e.KeyCode = Keys.F12 Then
Me.Close()
End If

Hope this helps.

Thanks.
