How to convert Application.PrevInstance in VB 6.0 to VB.NET?

Question

I have 'Applications.PrevInstance' in VB 6 code that I am trying to upgrade to .NET using VS 2008. Apparently this code is no longer valid. Does anyone have any ideas about upgraded solution? TIA

Solution

See here:

Public Sub Main()
   If PrevInstance() Then Exit Sub

   ' continue with your application
   UserName = Environ("UserName")
   ComputerName = Environ("COMPUTERNAME")

End Sub

Function PrevInstance() As Boolean
  If UBound(Diagnostics.Process.GetProcessesByName _
     (Diagnostics.Process.GetCurrentProcess.ProcessName)) _
     > 0 Then
     Return True
  Else
     Return False
  End If
End Function
