请问一个界面刷新的问题

Question

long CToubiDlg::OnInCoinMessage(WPARAM wp,LPARAM lp)
{ m_ticketbutton8.ShowWindow(SW_HIDE);
m_ticketbutton7.ShowWindow(SW_HIDE);
m_ticketbutton6.ShowWindow(SW_HIDE);
m_ticketbutton5.ShowWindow(SW_HIDE);
m_ticketbutton4.ShowWindow(SW_HIDE);
m_ticketbutton3.ShowWindow(SW_HIDE);
m_ticketbutton2.ShowWindow(SW_HIDE);
m_ticketbutton1.ShowWindow(SW_HIDE);
PostMessage(WM_STOPWORK);

}上面的代码中
m_ticketbutton8.ShowWindow(SW_HIDE);
m_ticketbutton7.ShowWindow(SW_HIDE);
m_ticketbutton6.ShowWindow(SW_HIDE);
m_ticketbutton5.ShowWindow(SW_HIDE);
m_ticketbutton4.ShowWindow(SW_HIDE);
m_ticketbutton3.ShowWindow(SW_HIDE);
m_ticketbutton2.ShowWindow(SW_HIDE);
m_ticketbutton1.ShowWindow(SW_HIDE);
是将8个按钮隐藏，WM_STOPWORK消息的处理时间比较长。但是执行OnInCoinMessage函数的结果时，这8个按钮确实隐藏了，
但是在完全隐藏之前，先变白了一下，然后才完全隐藏，请问这个问题怎样解决？

Answer 1

试试看m_ticketbutton8.SendMessage(WM_SHOWWINDOW, (WPARAM)(FALSE), (LPARAM)(NULL));
m_ticketbutton7.SendMessage(WM_SHOWWINDOW, (WPARAM)(FALSE), (LPARAM)(NULL));
m_ticketbutton6.SendMessage(WM_SHOWWINDOW, (WPARAM)(FALSE), (LPARAM)(NULL));
m_ticketbutton5.SendMessage(WM_SHOWWINDOW, (WPARAM)(FALSE), (LPARAM)(NULL));
m_ticketbutton4.SendMessage(WM_SHOWWINDOW, (WPARAM)(FALSE), (LPARAM)(NULL));
m_ticketbutton3.SendMessage(WM_SHOWWINDOW, (WPARAM)(FALSE), (LPARAM)(NULL));
m_ticketbutton2.SendMessage(WM_SHOWWINDOW, (WPARAM)(FALSE), (LPARAM)(NULL));
m_ticketbutton1.SendMessage(WM_SHOWWINDOW, (WPARAM)(FALSE), (LPARAM)(NULL));

在PostMessage之前插入下面代码看看 this->Invalidate();
this->UpdateWindow();
