[RESOLVED] [2005] Show an already running process

Howdy all,
Here's an example of what I'm trying to do. If my process has not started, then start it. If my process has started, then bring the currently running process to the front instead of opening another instance of it. For example

vb.net Code:

Private p As Process = Nothing
 
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    If p Is Nothing OrElse p.HasExited Then
        p = New Process()
        p.StartInfo.FileName = "c:\test.txt"
        p.Start()
    Else
        ' This process is already running so
        ' bring is to the front/maximize it
        ' instead of opening another one.
    End If
End Sub

I've waded through the Process class but have not found what I'm looking for. How can I, if in the example above, I already have an instance of NotePad open, bring it to the front instead of opening another instance?

Am I smelling API of some sort? Sorry if this turns out to be the inappropriate forum. Thanks.

No API needed...

Code:

---

    Private p As Process = Nothing
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If p Is Nothing OrElse p.HasExited Then
            p = New Process()
            p.StartInfo.FileName = "c:\test.txt"
            p.Start()
        Else
            ' This process is already running so
            ' bring is to the front/maximize it
            ' instead of opening another one.
            AppActivate(p.Id)
        End If
    End Sub

Perfect. Thank you.
