How to detect if a other process of my program is running?

[jorge]

Topic,
I know it has been askt, but can't find it anymore
Anyone?
Thanx in advance

Dim mut As New Mutex(False, "Name of your app as it is on the title bar")
If Not mut.WaitOne(0, false) Then
  'your app is running already
End if

This should help you

Do i need to define "Mutex"?
VB says:Type Mutext not defined??
Btw what if i don't have a form yet?

 

[mutant]

You can find Mutex in the Threading namespace.
If you dont have a form just specify the name of your application as a whole, not the form. Like "WindowsApplication2".

Dim mut As New Threading.Mutex(False, "apachemon")
If Not mut.WaitOne(0, False) Then
MsgBox("ApacheMon is running")
End If
Will do nothing?
apachemon <- is my exe and application name.

Found it
Needs to be the full exe name -> apachemon.exe as show in the taskmanager when looking at proccesses

It works for me without specifying the exe extension. All I used was the application name.
