buttonClicker

Hello,
I want to create a program for key pressing, but it doesn't work.
The program should press "F1" key every second or as I set it.

Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
Do
If CheckBox1.Checked = False Then
Exit Do
End If
System.Windows.Forms.SendKeys.Send("{F1}")
Loop
End Sub

Any Ideas? Please

What should on pressing F1

try this:

vb Code:

Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
     If CheckBox1.Checked = False Then
        Timer1.Enabled = False
     Else
        Timer1.Enabled = True
     End If
End Sub
 
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
     SendKeys.Send("{F1}")
End Sub

Yes poul you really did it right, I will only need to create a loop so it would get repeated:wave:
Thank you ::thumb:

why do you need a loop? once you enable the timer it'll keep ticking until you stop it

ok then it uses the interval does it ?

I need to control the times when the buttons clicks, sometime i will need two buttons to be clicked at different intervals

if you set the timer interval for 1000 milliseconds it'll click your button once every second. use 2 timers if you need different intervals for 2 seperate buttons
