禁用打印预览里的打印旋钮

禁用打印预览里的打印按钮
请教下：如何才能禁用打印预览里的打印按钮，在网上打到一段代码不知道放在什么地方。

PrintPreviewDialog ppDlg = new PrintPreviewDialog();
  //ppDlg.Controls[1].Visible = false;
  ToolStrip tool = ppDlg.Controls[1] as ToolStrip;
  if (tool != null)
  {
  tool.Items["printToolStripButton"].Visible= false;
  }
上面的是整个toolstrip禁用。这个是只禁用打印按钮。

[解决办法]

C# code

    private void button1_Click(object sender, EventArgs e)        {            PrintPreviewDialog ppDlg = new PrintPreviewDialog();            ToolStrip tool = ppDlg.Controls[1] as ToolStrip;            if (tool != null)            {                tool.Items["printToolStripButton"].Visible = false;            }            ppDlg.ShowDialog();        }
