protected override void WndProc(ref Message m)
{
//Console.WriteLine(m.Msg);
const int WM_SYSCOMMAND = 0x0112;
const int SC_CLOSE = 0xF060;
if (m.Msg == WM_SYSCOMMAND && (int)m.WParam == SC_CLOSE)
{
//捕捉关闭窗体消息
//用户点击关闭窗体控制按钮 注释为最小化窗体
//this.WindowState = FormWindowState.Minimized;

//窗体隐藏
this.Hide();
return;
}
base.WndProc(ref m);
