用SendMessage来实现

如下void CGetcwndDlg::OnButton3()<br /> {<br /> // TODO: Add your control notification handler code here<br /> SendMessage(WM_SYSCOMMAND,SC_MAXIMIZE,0);<br /> }</p> <p>void CGetcwndDlg::OnButton4()<br /> {<br /> // TODO: Add your control notification handler code here<br /> SendMessage(WM_SYSCOMMAND,SC_MINIMIZE,0);</p> <p>}</p> <p>void CGetcwndDlg::OnButton5()<br /> {<br /> // TODO: Add your control notification handler code here<br /> SendMessage(WM_SYSCOMMAND,SC_RESTORE,0);<br /> }
