Answered Program Leave?

[Zephlon]

I have tried many things, but the form's Leave/Deactivate events don't work. I have a program that has multiple forms open at once (one of them is a tool window), and I want to be able to detect when the user switches to a different program's window.
My program is a game, and I want it to pause automatically when not being played.

Can anyone help? Thanks in advance.

I use 2005 but my test showed the form's "Lost Focus" event should work.

 

[Zephlon]

But will the event be triggered when the user uses a window in the same program?

 

[formlesstree4]

Yes. VB.net would only pay attention to the form that actually lost focus. When the form loses focus, you can have the program call the pausing function/sub. When the form regains focus, have it resume. It doesn't matter if you have 100 forms from the same program open, the code is form specific.

So, is there a way to know when the user goes to a different program's window?

I think you might be looking for "Process.GetCurrentProcess".

Per Help:

Gets a new Process component and associates it with the currently active process.

I tried this,

    Private Sub TMautopause_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TMautopause.Tick
        If Not Process.GetCurrentProcess.ProcessName = "Tick-Tack-Ton.vshost" Then
            Pause(True)
        End If
    End Sub

but it didn't pause when I switched to a different window. Is there a such thing as "GetActiveProcess"?

GetCurrentProcess returns the Process instance of calling application, ie not relevant for external processes.

Try this:

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
    If ActiveForm IsNot Nothing Then
        Static game As Integer
        game += 1
        Me.Text = game.ToString
    End If 
End Sub

Awesome! The number stops incrementing when you change the form.

I works almost perfectly, but I'm sure that it's a different part interfering.
