三、对话框与控件的区别
四、MessageBox函数 1）函数详解
2）代码实例 #include //自定义的窗口过程 LRESULT CALLBACK MyWindowProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam) { switch (Msg) { case WM_DESTROY: PostQuitMessage(0);//可以使GetMessage返回0 return 0; case WM_LBUTTONDOWN: { //返回哪个按钮被点击 int ret= MessageBox(hWnd, L"这是一个模态对话框！", L"提示", MB_YESNO|MB_ICONEXCLAMATION | MB_DEFBUTTON2); /* #define IDOK 1 #define IDCANCEL 2 #define IDABORT 3 #define IDRETRY 4 #define IDIGNORE 5 #define IDYES 6 #define IDNO 7 #if(WINVER >= 0x0400) #define IDCLOSE 8 #define IDHELP 9 */ bool b = (ret == IDYES); }break; } return DefWindowProc(hWnd, Msg, wParam, lParam); } int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd) { //1.注册窗口类 WNDCLASS wnd; wnd.cbClsExtra = 0; wnd.cbWndExtra = 0; wnd.hbrBackground = (HBRUSH)(GetStockObject(GRAY_BRUSH));//背景色 wnd.hCursor = LoadCursor(NULL, IDC_ARROW);//光标 wnd.hIcon = LoadIcon(NULL, IDI_APPLICATION);//图标 //wnd.lpfnWndProc = DefWindowProc;//默认窗口过程函数，用于处理消息 wnd.lpfnWndProc = MyWindowProc;//自定义的窗口过程函数 wnd.lpszClassName = L"MrHuang";//窗口类名 wnd.lpszMenuName = NULL;//菜单资源名称 wnd.style = CS_HREDRAW | CS_DBLCLKS;//窗口类、样式 wnd.hInstance = hInstance;//实例句柄 RegisterClass(&wnd); //创建窗口(返回之前发送WM_CREATE) HWND hWnd = CreateWindow(L"MrHuang", L"第一个窗口程序", WS_OVERLAPPEDWINDOW, 100, 100, 400, 400, NULL, NULL, hInstance, NULL); //显示窗口 ShowWindow(hWnd, nShowCmd); //更新窗口(发送WM_PAINT) UpdateWindow(hWnd); //消息循环（收到WM_QUIT消息退出） MSG msg; while (GetMessage(&msg, NULL, 0, 0)) { TranslateMessage(&msg);//翻译消息 DispatchMessage(&msg);//分发消息到窗口过程 } }五、创建模态对话框 1）DialogBox函数
2）DialogProc函数
3）WM_INITDIALOG消息
4）WM_CTLCOLORDLG消息
5）EndDialog函数
6）代码实例 #include #include"resource.h" HBRUSH bsh=NULL; //自定义的对话框过程 INT_PTR CALLBACK MyDlgProc(HWND hDlg, UINT Msg, WPARAM wParam, LPARAM lParam) { switch (Msg) { case WM_INITDIALOG://在对话框显示之前立即发送 { HWND hEdit = CreateWindow(L"EdiT", L"这是一个编辑框控件哈哈哈", WS_CHILD | WS_VISIBLE | ES_MULTILINE | ES_NOHIDESEL, 30, 100, 200, 100, hDlg, (HMENU)1111, GetModuleHandle(NULL), NULL); return TRUE;//处理了消息 } case WM_CTLCOLORDLG : //回忆前面学习的WM_CTLCOLORBTN { //创建画刷 bsh= CreateSolidBrush(RGB(255, 0, 0)); return (INT_PTR)bsh; } case WM_COMMAND://菜单点击，按钮点击的消息 { switch ( LOWORD(wParam)) { case IDOK: //销毁对话框 EndDialog(hDlg, 666 ); //这里的666将作为DialogBox的返回值 DeleteObject(bsh); break; case IDCANCEL: EndDialog(hDlg, 999); DeleteObject(bsh); break; } return TRUE; } } return FALSE;//没处理此消息 } //自定义的窗口过程 LRESULT CALLBACK MyWindowProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam) { switch (Msg) { case WM_DESTROY: PostQuitMessage(0);//可以使GetMessage返回0 return 0; case WM_LBUTTONDOWN: { //根据对话框资源创建模态对话框 int ret= DialogBox(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_DIALOG1), hWnd, MyDlgProc); ret = ret; }break; } return DefWindowProc(hWnd, Msg, wParam, lParam); } int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd) { //1.注册窗口类 WNDCLASS wnd; wnd.cbClsExtra = 0; wnd.cbWndExtra = 0; wnd.hbrBackground = (HBRUSH)(GetStockObject(GRAY_BRUSH));//背景色 wnd.hCursor = LoadCursor(NULL, IDC_ARROW);//光标 wnd.hIcon = LoadIcon(NULL, IDI_APPLICATION);//图标 //wnd.lpfnWndProc = DefWindowProc;//默认窗口过程函数，用于处理消息 wnd.lpfnWndProc = MyWindowProc;//自定义的窗口过程函数 wnd.lpszClassName = L"MrHuang";//窗口类名 wnd.lpszMenuName = NULL;//菜单资源名称 wnd.style = CS_HREDRAW | CS_DBLCLKS;//窗口类、样式 wnd.hInstance = hInstance;//实例句柄 RegisterClass(&wnd); //创建窗口(返回之前发送WM_CREATE) HWND hWnd = CreateWindow(L"MrHuang", L"第一个窗口程序", WS_OVERLAPPEDWINDOW, 100, 100, 400, 400, NULL, NULL, hInstance, NULL); //显示窗口 ShowWindow(hWnd, nShowCmd); //更新窗口(发送WM_PAINT) UpdateWindow(hWnd); //消息循环（收到WM_QUIT消息退出） MSG msg; while (GetMessage(&msg, NULL, 0, 0)) { TranslateMessage(&msg);//翻译消息 DispatchMessage(&msg);//分发消息到窗口过程 } }六、创建非模态对话框 1）CreateDialog函数
2）IsDialogMessage函数
3）代码实例 #include #include"resource.h" HBRUSH bsh = NULL; HWND hDlg = NULL; //自定义的对话框过程 INT_PTR CALLBACK MyDlgProc(HWND hDlg, UINT Msg, WPARAM wParam, LPARAM lParam) { switch (Msg) { case WM_INITDIALOG://在对话框显示之前立即发送 { HWND hEdit = CreateWindow(L"EdiT", L"这是一个编辑框控件哈哈哈", WS_CHILD | WS_VISIBLE | ES_MULTILINE | ES_NOHIDESEL, 30, 100, 200, 100, hDlg, (HMENU)1111, GetModuleHandle(NULL), NULL); return TRUE;//处理了消息 } case WM_CTLCOLORDLG: //回忆前面学习的WM_CTLCOLORBTN { //创建画刷 bsh = CreateSolidBrush(RGB(255, 0, 0)); return (INT_PTR)bsh; } case WM_COMMAND://菜单点击，按钮点击的消息 { switch (LOWORD(wParam)) { case IDOK: case IDCANCEL: //销毁对话框 DestroyWindow(hDlg); DeleteObject(bsh); break; } return TRUE; } } return FALSE;//没处理此消息 } //自定义的窗口过程 LRESULT CALLBACK MyWindowProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam) { switch (Msg) { case WM_DESTROY: PostQuitMessage(0);//可以使GetMessage返回0 return 0; case WM_LBUTTONDOWN: { //创建非模态对话框，返回窗口句柄 （DialogBox返回的是INT_PTR） hDlg =CreateDialog(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_DIALOG1) , hWnd, MyDlgProc); //显示非模态对话框 ShowWindow(hDlg, SW_SHOW); }break; } return DefWindowProc(hWnd, Msg, wParam, lParam); } int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd) { //1.注册窗口类 WNDCLASS wnd; wnd.cbClsExtra = 0; wnd.cbWndExtra = 0; wnd.hbrBackground = (HBRUSH)(GetStockObject(GRAY_BRUSH));//背景色 wnd.hCursor = LoadCursor(NULL, IDC_ARROW);//光标 wnd.hIcon = LoadIcon(NULL, IDI_APPLICATION);//图标 //wnd.lpfnWndProc = DefWindowProc;//默认窗口过程函数，用于处理消息 wnd.lpfnWndProc = MyWindowProc;//自定义的窗口过程函数 wnd.lpszClassName = L"MrHuang";//窗口类名 wnd.lpszMenuName = NULL;//菜单资源名称 wnd.style = CS_HREDRAW | CS_DBLCLKS;//窗口类、样式 wnd.hInstance = hInstance;//实例句柄 RegisterClass(&wnd); //创建窗口(返回之前发送WM_CREATE) HWND hWnd = CreateWindow(L"MrHuang", L"第一个窗口程序", WS_OVERLAPPEDWINDOW, 100, 100, 400, 400, NULL, NULL, hInstance, NULL); //显示窗口 ShowWindow(hWnd, nShowCmd); //更新窗口(发送WM_PAINT) UpdateWindow(hWnd); //消息循环（收到WM_QUIT消息退出） MSG msg; while (GetMessage(&msg, NULL, 0, 0)) { if (IsDialogMessage(hDlg, &msg)) //对话框处理过 { continue; } TranslateMessage(&msg);//翻译消息 DispatchMessage(&msg);//分发消息到窗口过程 } }七、创建对话框主窗口程序 1）创建对话框为主窗口的步骤
2）设置对话框图标
3）代码实例 #include #include"resource.h" //自定义的对话框窗口过程 INT_PTR CALLBACK MyDlgProc(HWND hDlg, UINT Msg, WPARAM wParam, LPARAM lParam) { switch (Msg) { case WM_INITDIALOG: { //设置对话框标题 SetWindowText(hDlg, L"用户登录"); //设置对话框图标 HICON icon = LoadIcon(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_ICON1)); SendMessage(hDlg, WM_SETICON, ICON_SMALL, (LPARAM)icon); DestroyIcon(icon); return TRUE; } case WM_COMMAND: { UINT id = LOWORD(wParam); switch (id) { case ID_BTN_LOGIN : { TCHAR name[64] = { 0 }; GetDlgItemText(hDlg, IDC_EDIT_NAME, name, 64); TCHAR pwd[64] = { 0 }; GetDlgItemText(hDlg, IDC_EDIT_PWD, pwd, 64); TCHAR str[256] = { 0 }; wsprintf(str, L"用户名：%s 密码:%s", name, pwd); MessageBox(hDlg, str, L"提示", MB_OK); } break; case IDCANCEL: DestroyWindow(hDlg);//销毁非模态对话框 PostQuitMessage(0);//WM_QUIT退出消息循环 break; } return TRUE; } default: break; } return FALSE; } int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd) { //创建非模态对话框 HWND hDlg=CreateDialog(hInstance, MAKEINTRESOURCE(IDD_DIALOG1), GetDesktopWindow(), MyDlgProc); //显示对话框 ShowWindow(hDlg, SW_SHOW); //消息循环 MSG msg; while (GetMessage(&msg, NULL, 0,0)) { TranslateMessage(&msg); DispatchMessage(&msg); } return TRUE; }
