Launch only one instance of application

i have associated ".ctr" file with our inhouse application. when user doubleclicks the ".ctr" file our application is launched.

now if the application is already open, instead of launching a new instance, i just want to open the ".ctr" file as a 'child-window' within the already running application, how can i do this?

hi,
in the form load event check this application has previous instance or not

If App.PrevIntance Then
    'Application is already running, so open it in a child form
Else
   'Application is not runnnig
End If
