Detect launch of an external application

Question

I would like to know if it is possible to detect when the window of a named external application is launched and how to.

Example: When firefox or notepad(preferably by process name. Not notepad.exe for example) is ran, minimize my application.

Answer 1

For each p as process in process.GetProcesses()
If p.processname = "notepad" then
'Do something
Else
'Do Else Something
End If
Next

Answer 2

Here two ways, that would work:

 Dim plist() As Process = Process.GetProcessesByName("notepad")
 If plist.Length > 0 Then
      ' notepad is running at least once
 Else
      ' notepad is not running
 End If

or

    Dim notepadRunning As Boolean = False
    For Each p As Process In Process.GetProcesses
        If p.ProcessName = "notepad" Then notepadRunning = True
    Next
    If notepadRunning Then
        ' notepad is running at least once
    Else
        'notepad is not running
    End If

Note: the second way is just a glorified version of the first...
