ESC退出全屏（求助）

[华亭真人]

按ESC不能退出全屏 相关代码如下,请高手帮忙

void CMainFrame::OnFullscreen() 
{
	// TODO: Add your command handler code here
	GetWindowPlacement(&m_OldWndPlacement);
	CRect WindowRect;
	GetWindowRect(&WindowRect);
	CRect ClientRect;
	RepositionBars(0,0xffff,AFX_IDW_PANE_FIRST,reposQuery,&ClientRect);
	ClientToScreen(&ClientRect);
	int nFullWidth=GetSystemMetrics(SM_CXSCREEN);
	int nFullHeight=GetSystemMetrics(SM_CYSCREEN);
	m_FullScreenRect.left=WindowRect.left-ClientRect.left;
	m_FullScreenRect.right=WindowRect.right-ClientRect.right+nFullWidth;
	m_FullScreenRect.top=WindowRect.top-ClientRect.top;
	m_FullScreenRect.bottom=WindowRect.bottom-ClientRect.bottom+nFullHeight;
	m_bFullScreen=TRUE;
	WINDOWPLACEMENT wndpl;
	wndpl.length=sizeof(WINDOWPLACEMENT);
	wndpl.flags=0;
	wndpl.showCmd=SW_SHOWNORMAL;
	wndpl.rcNormalPosition=m_FullScreenRect;
	SetWindowPlacement(&wndpl);

}

void CMainFrame::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI) 
{
	// TODO: Add your message handler code here and/or call default
	if(m_bFullScreen)
	{
		lpMMI->ptMaxSize.x=m_FullScreenRect.Width();
		lpMMI->ptMaxSize.y=m_FullScreenRect.Height();
		lpMMI->ptMaxPosition.x=m_FullScreenRect.Width();
		lpMMI->ptMaxPosition.y=m_FullScreenRect.Height();
		lpMMI->ptMaxTrackSize.x=m_FullScreenRect.Width();
		lpMMI->ptMaxTrackSize.y=m_FullScreenRect.Height();
	}

	CFrameWnd::OnGetMinMaxInfo(lpMMI);
}

void CMainFrame::EndFullScreen()
{
	if(m_bFullScreen)
	{
		ShowWindow(SW_HIDE);
		SetWindowPlacement(&m_OldWndPlacement);
	}

}

void CMainFrame::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags) 
{
	// TODO: Add your message handler code here and/or call default
	if(nChar==VK_ESCAPE)
	{
		CMainFrame *pFrame=(CMainFrame*)AfxGetApp()->m_pMainWnd;
		pFrame->EndFullScreen();
	}

	CFrameWnd::OnKeyDown(nChar, nRepCnt, nFlags);
}

在这个消息函数中加
BOOL CMainFrame::PreTranslateMessage(MSG* pMsg)
{
if (WM_KEYDOWN == pMsg->message)
{
switch(pMsg->wParam)
{

case VK_ESCAPE:
{
CMainFrame *pFrame=(CMainFrame*)AfxGetApp()->m_pMainWnd;
pFrame->EndFullScreen();

}break;
}
}
return CMDIFrameWnd::PreTranslateMessage(pMsg);
}

楼上的正解，自己要把消息泵函数写出来。也有实现组合键的类，楼主也可以自己找一下。

来点简单的，设个加速键，响应加速键的事件。
