本程序实现当你点击“X”或按下“Alt+F4”时,使窗体最小化, 具体源代码如下:
protected override void WndProc(ref Message m)
{
const int WM_SYSCOMMAND = 0x0112;
const int SC_CLOSE = 0xF060;
if (m.Msg == WM_SYSCOMMAND && (int) m.WParam == SC_CLOSE)
{
// User clicked close button
this.WindowState = FormWindowState.Minimized;
return;
}
base.WndProc(ref m);
}
