wince按键中断的检测

重载PreTranslateMessage函数

实现PreTranslateMessage(MSG* pMsg) 

代码如下

BOOL CKeyTestDlg::PreTranslateMessage(MSG* pMsg) 
{
	// TODO: Add your specialized code here and/or call the base class
	if(pMsg->message == WM_KEYDOWN)// 按键按下
	{
		CString tmp;
		tmp.Format(L"KeyCode:%#x. key: ", pMsg->wParam);
		BOOL isExit = FALSE;
		BOOL isDoChange = TRUE;
		
		CString str = L"";
		if(pMsg->wParam == VK_BACK) 		str = L"退格";
		else if(pMsg->wParam == VK_RETURN)	{str = L"回车";	isExit = TRUE;}
		else if(pMsg->wParam == VK_SCAN)	str = L"扫描键";
		else if(pMsg->wParam == VK_ESCAPE){
			str = L"ESC";
			isExit = TRUE;
		}
		else if(pMsg->wParam == VK_SPACE)	str = L"空格键";
		else if(pMsg->wParam == VK_LEFT)	str = L"向左";
		else if(pMsg->wParam == VK_UP)		str = L"向上";
		else if(pMsg->wParam == VK_RIGHT)	str = L"向右";
		else if(pMsg->wParam == VK_DOWN)	str = L"向下";
		else if(pMsg->wParam == VK_DELETE)	str = L"删除";
		else if(pMsg->wParam == VK_TSTAR && GetKeyState(VK_SHIFT)<0){
			str += L"*";
		}
		else if(pMsg->wParam == VK_TPOUND && GetKeyState(VK_SHIFT)<0){
			str += L"#";
		}
		else if(pMsg->wParam>=VK_T0 && pMsg->wParam<=VK_T9){
			str.Format(L"%d", pMsg->wParam-VK_T0);
		}
		else if(pMsg->wParam == VK_F1)		str = L"F1";
		else if(pMsg->wParam == VK_TEND)	str = L"挂机键";
		else if(pMsg->wParam == VK_TTALK)	str = L"通话键";
		else{
			isDoChange = FALSE;
		}
		
		mEdit.SetWindowTextW(tmp + str);
		
		if(isDoChange){
		/*SetPowerRequirement(TEXT("BKL1:"), D1, POWER_NAME, NULL, 0);
		HANDLE bklEvent = CreateEvent(NULL, false, false, L"BackLightChangeEvent");
		if(bklEvent != NULL){
		SetEvent(bklEvent);
		CloseHandle(bklEvent);
		}
		const TCHAR szevtUserInput[] = TEXT("PowerManager/ActivityTimer/UserActivity"); 
		HANDLE bklEvent = CreateEvent(NULL, false, false, szevtUserInput);
		if(bklEvent != NULL){
		SetEvent(bklEvent);
		CloseHandle(bklEvent);
		}*/
		}
		
		if(isExit)	return TRUE;
	}
	
	
	return CDialog::PreTranslateMessage(pMsg);
}
