KeyDown for spacebar

[MajorWoody]

Hi all,

I am having trouble using keydown for the spacebar in a form.

I would like the spacebar to start/stop a StopWatch that I have running. I can get that to work fine but whenever I am focused on another button it also executes that buttons function also.

I know that is the default behavior for the enter key and spacebar but I would like to override that.

Could someone point me in the right direction?


Thanks in advance,
Major

I cant remember if this is a WPF specific thing but in the keydown event of your form can you set e.Handled to True or does that property not even exist?

If you register the Spacebar as a hotkey then it will no longer do that.

What do you mean by register?

This is what I have:

    Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown

        If e.KeyCode = Keys.Space Then
            swGame.stop()
        End If

    End Sub

However, when I click another button and then press the spacebar it stops the clock but also 'presses' the button.

Public Class Form1
 
    Public Sub New()
        Me.InitializeComponent()
        Me.KeyPreview = True
    End Sub
 
    Private Sub Button1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Button1.KeyDown
        If e.KeyCode = Keys.Space Then
            e.SuppressKeyPress = True
        End If
    End Sub
 
    Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
        If e.KeyCode = Keys.Space Then
            MessageBox.Show("Toggle start/stop")
        End If
    End Sub
 
End Class

This would stop it, however it puts the Button into a depressed state, although it doesn't get clicked. Not sure why it does that.

Ok, I'll try that, thanks!
