От него наследую класс CXFrame, потом CXMyFrame.
Если создаю окно с помощью ::CreateWindowEx:
| Код |
CMainFrame MainFrame;
MainFrame.bCreate(0, HWND_DESKTOP, 400, 400, 600, 430, 0, 0);
|
то все нормально работает, а если из ресурсов:
| Код |
CMainFrame MainFrame;
MainFrame.bCreateRes(IDD_DIALOGBAR, HWND_DESKTOP);
|
то окно содается, но не реагирует ни на какие действия (не идет обработка сообщений),
только можно перемещять мышкой.
Где-то косяк в методе s_BaseWndProc...
Если чего-то в коде не хватает - выложу. |
