步骤二SDI界面创建后马上创建自己的Dialog
BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{HWND hWnd;hInst hInstance; // Store instance handle in our global variablehWnd CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW,CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);if (!hWnd){return FALSE;}hWndGlobal hWnd;SetWindowText(hWnd, Dialog as Application - VC6);nCmdShow SW_SHOW;ShowWindow(hWnd, nCmdShow);UpdateWindow(hWnd);// Create DIALOG boxHWND hDlg CreateDialog(hInst, MAKEINTRESOURCE(IDD_MAINFORM), hWnd, (DLGPROC)Mainform);// Show DIALOG boxShowWindow(hDlg, SW_SHOWNA);UpdateWindow(hWnd);RECT rectDlgw, rectDlgc, rectMainw, rectMainc;GetWindowRect(hWnd, rectMainw); //Dialog window areaGetClientRect(hWnd, rectMainc); //Dialog client areaGetWindowRect(hDlg, rectDlgw); //Dialog window areaGetClientRect(hDlg, rectDlgc); //Dialog client areaRECT rect;HWND hwndDTGetDesktopWindow(); GetClientRect(hwndDT,rect); LONG dtWidthrect.right-rect.left; LONG dtHeightrect.bottom-rect.top; RECT rectbar;HWND taskbar FindWindow(Shell_TrayWnd, );GetWindowRect(taskbar, rectbar);//if(rectbar.top0) //TASKBAR at bottom//if(rectbar.left0) //TASKBAR at left//Center MAINWINDOW at desktop client areaMoveWindow(hWnd, (rectbar.right-rectbar.left)(dtWidth-(rectMainw.right-rectMainw.left))/2, (dtHeight-(rectMainw.bottom-rectMainw.top))/2, (rectDlgw.right-rectDlgw.left), (rectDlgw.bottom-rectDlgw.top) (rectDlgc.bottom-rectDlgc.top)-(rectMainc.bottom-rectMainc.top)1, 1);//Align inner DIALOG to MAINWINDOWMoveWindow(hDlg, 0, 0, rectDlgw.right, rectDlgw.bottom, 1);UpdateWindow(hWnd);return TRUE;
} 上面这两句是重点这两句下面的功能是计算后调整SDI窗体让它刚好将Dialog装入进去并将它们显示在屏幕中央位置。
(DLGPROC)Mainform 参数指的是回调函数在CALLBACK函数Mainform中对Dialog Editor摆放的控件进行操作。
步骤三操作Dialog 控件
LRESULT CALLBACK Mainform(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{switch (message){case WM_INITDIALOG:{//Change DIALOG iconHICON hIcon LoadIcon(hInst, MAKEINTRESOURCE(IDI_ICON3));SetClassLong(hDlg, GCL_HICONSM, (LONG)hIcon);GetDlgItem(hDlg, IDC_PROGRESS1);SendMessage(GetDlgItem(hDlg, IDC_PROGRESS1), PBM_SETRANGE, MAKEWPARAM(0, 0), MAKELPARAM(0, 59)); //SendMessage(GetDlgItem(hDlg, IDC_PROGRESS1), PBM_SETPOS, (WPARAM)(0, 65), (LPARAM)(0, 0)); SetTimer(hDlg, 1, 1000, NULL);//KillTimer(hDlg, 1);break;/*typedef struct _SYSTEMTIME {WORD wYear;WORD wMonth;WORD wDayOfWeek;WORD wDay;WORD wHour;WORD wMinute;WORD wSecond;WORD wMilliseconds;} SYSTEMTIME, *PSYSTEMTIME, *LPSYSTEMTIME;*/SYSTEMTIME st, lt;GetSystemTime(st);GetLocalTime(lt);SendMessage(GetDlgItem(hDlg, IDC_PROGRESS1), PBM_SETPOS, (WPARAM)(0, st.wSecond), (LPARAM)(0, 0)); break;case WM_TIMER:{SYSTEMTIME st, lt;GetSystemTime(st);GetLocalTime(lt);SendMessage(GetDlgItem(hDlg, IDC_PROGRESS1), PBM_SETPOS, (WPARAM)(0, st.wSecond), (LPARAM)(0, 0)); }break;case WM_PAINT:break;case WM_CTLCOLORDLG:break;case WM_ERASEBKGND:case WM_NCPAINT:break;case WM_SYSCOMMAND:if (wParam SC_CLOSE){EndDialog (hDlg, TRUE);KillTimer(hDlg, 1);PostQuitMessage(0);return(TRUE);}break;case WM_COMMAND://if (LOWORD(wParam) IDOK || LOWORD(wParam) IDCANCEL) if (LOWORD(wParam) IDOK) {EndDialog(hDlg, LOWORD(wParam));KillTimer(hDlg, 1);PostQuitMessage(0);return TRUE;}if (LOWORD(wParam) IDCANCEL){if (!IsDlgButtonChecked(hDlg, IDC_CHECK1)){CheckDlgButton(hDlg, IDC_CHECK1, BST_CHECKED);}if (!IsDlgButtonChecked(hDlg, IDC_RADIO1)){CheckDlgButton(hDlg, IDC_RADIO1, BST_CHECKED);}}if (LOWORD(wParam) IDC_BUTTON4){SendMessage(hDlg, WM_SYSCOMMAND, SC_MAXIMIZE, 0); }if (LOWORD(wParam) IDC_BUTTON3){SendMessage(hDlg, WM_SYSCOMMAND, SC_MINIMIZE, 0); }if (LOWORD(wParam) IDC_BUTTON2){SetWindowText(GetDlgItem(hDlg, IDC_EDIT1),Message 1); SetWindowText(GetDlgItem(hDlg, IDC_EDIT2),Message 2); SetWindowText(GetDlgItem(hDlg, IDC_EDIT3),Message 3); }break;}return FALSE;
}上面的代码包括对Edit文本框的操作对Button的操作对复选和Radio的操作还用到了一个SYSTEMTIME结构和操作函数让界面上的指示条随秒而动。对MFC的习练比WIN32功能多一些编写程序比WIN32方便但代码不如WIN32程序精练直接。
