I don't think there is any one specific way to limit a program to a single instance. Some use a registry entry to determine if there is an instance already running, while others use a file or create a system-wide semaphore (see MSDN for CreateSemaphore() win32 api function)

Hi,

Use this Code :
In ur MDIFormLoad Or the StartUp Form Load.

Private Sub MYMDIForm_Load()
    If App.PrevInstance Then
        End
    End If
End Sub
