我正在通过以下方法注册我的班级:
BOOL CNDSClientDlg::InitInstance()
{
//Register Window Updated on 16th Nov 2010, @Subhen
// Register our unique class name that we wish to use
WNDCLASS wndcls;
memset(&wndcls, 0, sizeof(WNDCLASS));
wndcls.style = CS_DBLCLKS | CS_HREDRAW | CS_VREDRAW;
wndcls.lpfnWndProc = ::DefWindowProc;
wndcls.hInstance = AfxGetInstanceHandle();
wndcls.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);
wndcls.lpszMenuName = NULL;
//Class name for using FindWindow later
wndcls.lpszClassName = _T("CNDSClientDlg");
// Register new class and exit if it fails
if(!AfxRegisterClass(&wndcls)) // [C]
{
return FALSE;
}
}
然后调用 InitInstance 方法并在类的构造函数中创建窗口:
CNDSClientDlg::CNDSClientDlg(CWnd* pParent /*=NULL*/)
: CDialog(CNDSClientDlg::IDD, pParent)
{
InitInstance();
HWND hWnd;
hInst = AfxGetInstanceHandle(); // Store instance handle in our global variable
hWnd = CreateWindow(_T("CNDSClientDlg"), "NDS", WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInst, NULL);
}
现在在我的另一个应用程序中,我正在找到窗口并试图将其置于顶部:
编辑 能够使用以下代码带来新创建的 Windows
CWnd *pWndPrev = NULL;
CWnd *FirstChildhWnd = NULL;
pWndPrev = CWnd::FindWindow(_T("CNDSClientDlg"),NULL);
if(pWndPrev != NULL)
{
//pWndPrev->BringWindowToTop();
WINDOWPLACEMENT wndplacement;
pWndPrev->GetWindowPlacement(&wndplacement);
wndplacement.showCmd = SW_RESTORE;
pWndPrev->SetWindowPlacement(&wndplacement);
pWndPrev->SetForegroundWindow();
FirstChildhWnd = pWndPrev->GetLastActivePopup();
if (pWndPrev != FirstChildhWnd)
{
// a pop-up window is active, bring it to the top too
FirstChildhWnd->GetWindowPlacement(&wndplacement);
wndplacement.showCmd = SW_RESTORE;
FirstChildhWnd->SetWindowPlacement(&wndplacement);
FirstChildhWnd->SetForegroundWindow();
}
我能够找到pWndPrev
不是 NULL 的窗口,但它没有将我的应用程序放在前面。我是否需要注册任何其他类而不是 CNDSClientDlg。我想把我的 MFC 应用程序带到顶部。
