Keydown Question

[dtgreer]

I have a form with two buttons. I would like to add keyboard shortcuts for those buttons and have looked through all of the postings I could find on this topic. I did see one post which had the code below.

It works for the first time that the user presses F2 but only that one time. Can you please help out a newbie?

Private Sub PB_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
        If e.KeyCode = Keys.F2 Then
            MsgBox("pushed F2")
        End If
    End Sub

Try

If Asc(e.KeyChar) = Keys.F2 Then

Try setting the KeyPreview property of the Form to True.

That should sort it out.

He said it worked one time, but not twice. If KeyPreview was not set to true, it wouldn't work at all, ever, right?

Ok I am getting this error.

'KeyChar' is not a member of 'System.Windows.Forms.KeyEventArgs'.

Is there something I need to import?

Is PB a Form or a control?

[dtgreer]

Sorry it is a form

Sorry it is a form

Ohhhh....then

'KeyChar' is not a member of 'System.Windows.Forms.KeyEventArgs'.

is correct, and no you didn't miss anything.

When I run your original code from the Form's KeyDown event, it works for me each and everytime.

well thank you for your help. It is working perfectly now.

Did you do or change anything?

[dtgreer]

the only change I made was set the Keypreview to true.. It is odd that it would work at all with it set to false.

I have tested it again and it appears to work the same whether I set the Keypreview attribute of the form to true or not. The reason it would only work one time before is the msgbox pop-up.

Whenever the msgbox will open, I guess the form loses focus even if I close the msgbox.

I am sure you can explain why that happens and how to fix that problem.

Correction.

Scenario 1: Keypreview set to false. Works but if a msgbox or anything else taking focus pop-ups then it will no longer work.

Scenario 2: Keypreview set to true. Works correctly regardless of msgboxes etc.
