It is completely lazy code. Usually we want to screen you, press the PRTSC key, then stick to the drawing board.
The following is the simulated code.
private void menuItem1_Click (object sender, System.EventArgs e) {SendKeys.SendWait ( "^ {PRTSC}"); IDataObject iData = Clipboard.GetDataObject (); if (iData == null) return; if (iData.GetDataPresent (DataFormats .Bitmap) {image img = (image) iData.getdata (dataformats.bitmap); graphics g = this.creategraphics (); g.drawimageunscaled (IMG, 0, 0);}}
