Функция ReadFile должна копировать содерживое файла в sReadBuffer (строка 299) | Код |
ReadFile(iHandle, &sReadBuffer, MAXREAD, NULL,&gOverlapped);
|
а потом отобразить содержимое в окне | Код |
SetWindowText (hWndEdit,sReadBuffer);
|
... но почему то это не происходиот ... помогите пожалуйста Это сообщение отредактировал(а) Logit - 21.8.2006, 09:04 |
