Hy


How can I do to when a program is running, if I open it again, it won't open but it will activate the program already opened. Like winamp.



Thank you

When the programe is running the first time, it will go to the there

Public Class Initialise
    
    Shared Sub Main()

        ' Prevent Multiple Instances of the Application
        Dim appProcesses As Process()

        appProcesses = Process.GetProcessesByName(Diagnostics.Process.GetCurrentProcess.ProcessName)

        If appProcesses.Length > 1 Then
            Application.Exit()
        Else
'''''''''''''''''''''It will go here''''''''''''''''''''
            Dim formMain = New frmMain()

            Application.Run(formMain)
        End If
    End Sub
End Class

But the second time it will go there

Public Class Initialise
    
    Shared Sub Main()

        ' Prevent Multiple Instances of the Application
        Dim appProcesses As Process()

        appProcesses = Process.GetProcessesByName(Diagnostics.Process.GetCurrentProcess.ProcessName)

        If appProcesses.Length > 1 Then
'''''''''''''''''''''It will go here''''''''''''''''''''
            Application.Exit()
        Else

            Dim formMain = New frmMain()

            Application.Run(formMain)
        End If
    End Sub
End Class

I want to activate(focus) the first program witch is running when the second close(Application.Exit()).


Like winamp: When click on the shortcut of winamp and it aready open, It will focus on the program already open.
