how can i remove the menubar from an embedded application?

heres what i have so far, which removes the titlebar:

vb Code:
  1. Dim proc As New Diagnostics.Process

  2. proc.StartInfo.FileName = "calc.exe"

  3. proc.Start()

  4. proc.WaitForInputIdle()

  5. SetParent(proc.MainWindowHandle, Me.Panel2.Handle)

  6. SendMessage(proc.MainWindowHandle, WM_SYSCOMMAND, SC_MAXIMIZE, 0)

  7. InitialStyle = GetWindowLong(proc.MainWindowHandle, GWL_STYLE)

  8. SetWindowLong(proc.MainWindowHandle, GWL_STYLE, InitialStyle And Not WS_BORDER)
