C#

• Change the NONCLIENTMETRICS to a struct (NB: You'll have to remove the constructor.)
• Change the declaration to:
  
  cd

  [DllImport("User32.dll")]
  public static extern bool SystemParametersInfo(int Action, 
      int uiParam, ref NONCLIENTMETRICS pvParam, int WinIni);

• Change the call to:
  
  C#

  NONCLIENTMETRICS ncm = new NONCLIENTMETRICS();
  ncm.cbSize = Marshal.SizeOf(ncm);
  bool b = SystemParametersInfo(SPI_GETNONCLIENTMETRICS, 
      ncm.cbSize, ref ncm, 0);
