注：以下代码以一个名为CTest6Dlg的对话框类为例--------------------------------------------------------------------------------1. 在任务栏隐藏对话框ModifyStyleEx(WS_EX_APPWINDOW, WS_EX_TOOLWINDOW);--------------------------------------------------------------------------------2. 使对话框为顶层窗口SetWindowPos(&this->wndTopMost, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE);--------------------------------------------------------------------------------3. 在运行时添加最大化，最小化按钮SetWindowLong(this->m_hWnd, GWL_ST YLE,GetWindowLong(this->m_hWnd, GWL_ST YLE) |WS_MINIM IZEBOX | WS_MAXIMIZEBOX);UpdateWindow();--------------------------------------------------------------------------------4. 使能对话框右上角关闭按钮在OnInitDialog中方法一：CMenu* menu = GetSystemMenu(FALSE);menu->Modify M enu(SC_CLOSE, MF_BYCOMMAND | M F_GRAYED );方法二：CMenu* menu = GetSystemMenu(FALSE);menu->EnableMenuItem(SC_CLOSE, MF_BYCOMMAND | MF_GRAYED);--------------------------------------------------------------------------------5. 当对话框一部分在屏幕外时，显示全部对话框SendMessage(DM_REPOSITION);--------------------------------------------------------------------------------6. 改变鼠标外形添加WM_SETCURSOR 消息映射函数BOOL CTest6Dlg::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) {SetCursor(AfxGetApp()->LoadStandardCursor(IDC_HELP));return 0;}--------------------------------------------------------------------------------7. 改变对话框背景色和文本颜色在CTest6App的InitInstance中添加SetDialogBkColor(RGB(255,0,0), RGB(0,255,0));--------------------------------------------------------------------------------8. 改变对话框caption上的图标导入自己的图标资源到工程中，把原来ID为IDR_MAINFRAME 的资源删除，把新的图标的ID命名为IDR_MAINFRAME --------------------------------------------------------------------------------9. 在主对话框显示前，显示一个login对话框BOOL CTest6App::InitInstance(){//...int nResponse;CLoginDlg loginDlg;nResponse = loginDlg.DoModal();if (nResponse == IDOK){}if (nResponse == IDCANCEL){return FALSE;}CTest6Dlg dlg;m_pMainWnd = &dlg;int nResponse = dlg.DoModal();if (nResponse == IDOK ){}else if (nResponse == IDCANCEL){}return FALSE;}然后重载CLoginDlg对话框的哦OnOK()，在其中判断条件void CLoginDlg::OnOK(){if (条件满足)CDialog::OnOK();elseAfxMessageBox(_T("invalid password!"));}--------------------------------------------------------------------------------10. 在对话框中添加工具栏方法一：添加以下代码到OnInitDialog 中if ( !m_wndToolBar.Create(this) || !m_wndToolBar.LoadToolBar(IDR_TOOLBAR1) ){TRACE0("Failed to Create Dialog Toolbar\n");EndDialog(IDCANCEL);}CRect rcClientOld; // 久客户区RECTCRect rcClientNew; // 加入TOOLBAR后的CLIENT RECTGetClientRect(rcClientOld); //// Called to reposition and resize control bars in the client area of a window// The reposQuery FLAG does not really traw the Toolbar. It only does the calculations.// And puts the new ClientRect v alues in rcClientNew so we can do the rest of the Math.//重新计算RECT大小RepositionBars(AFX_IDW_CONT ROLBAR_FIRST,AFX_IDW_CONTROLBAR_LAST,0,reposQuery,rcClientNew);// All of the Child Windows (Controls) now need to be moved so the Tollbar does not cov er them up. //所有的子窗口将被移动，以免被TOOLBAR覆盖// Offest to move all child controls after adding Tollbar//计算移动的距离CPoint ptOffset(rcClientNew.left-rcClientOld.left,rcClientNew.top-rcClientOld.top);CRect rcChild;CWnd* pwndChild = GetWindow(GW_CHILD); //得到子窗口while(pwndChild) // 处理所有子窗口{//移动所有子窗口pwndChild->GetWindowRect(rcChild);ScreenToClient(rcChild);rcChild.OffsetRect(ptOffset);pwndChild->MoveWindow(rcChild,FALSE);pwndChild = pwndChild->GetNextWindow();}CRect rcWindow;GetWindow Rect(rcWindow); // 得到对话框RECTrcWindow.right += rcClientOld.Width() - rcClientNew.Width(); // 修改对话框尺寸rcWindow.bottom += rcClientOld.Height() - rcClientNew.Height();Mov eWindow(rcWindow,FALSE); // Redraw WindowRepositionBars(AFX_IDW_CONT ROLBAR_FIRST,AFX_IDW_CONT ROLBAR_LAST,0);方法二：/dialog/dlgtoolstatusbar.asp--------------------------------------------------------------------------------11.响应对话框的最大化、最小化、关闭、恢复事件方法一：添加WM_SYSCOMMAND 消息映射函数v oid CTest6Dlg::OnSysCommand(UINT nID, LPARAM lParam) {if ( (nID & 0xFFF0) == IDM_ABOUTBOX ){CAboutDlg dlgAbout;dlgAbout.DoModal();}else{if ( nID == SC_MAXIMIZE ){AfxMessageBox(_T("最大化"));}else if ( nID == SC_MINIMIZE ){AfxMessageBox(_T("最小化"));}else if ( nID == SC_CLOSE ){AfxMessageBox(_T("关闭"));}CDialog::OnSysCommand(nID, lParam);}方法二：添加WM_SIZE 消息映射函数v oid CTest6Dlg::OnSize(UINT nT y pe, int cx, int cy){CDialog::OnSize(nT y pe, cx, cy);if ( nT y pe == SIZE_MAXIM IZED ){AfxMessageBox(_T("最大化"));}else if ( nT ype == SIZE_MINIMIZED ){AfxMessageBox(_T("最小化"));}else if ( nT ype == SIZE_RESTORED ){AfxMessageBox(_T("恢复"));}}--------------------------------------------------------------------------------12.代码实现窗口最小化，最大化，关闭PostMessage(WM_SYSCOMMAND, SC_MINIMIZE);PostMessage(WM_SYSCOMMAND, SC_MAXIMIZE);PostMessage(WM_SYSCOMMAND, SC_CLOSE);--------------------------------------------------------------------------------13.按下ESC和ENTER键时禁止关闭对话框方法一：(1) 重载OnCancel和OnOk，屏蔽其中的CDialog::OnCancel()和CDialog::OnOk();(2) 添加以下代码v oid CTest6Dlg::OnSysCommand(UINT nID, LPARAM lParam){if ((nID & 0xFFF0) == IDM_ABOUTBOX){CAboutDlg dlgAbout; //if you have an about dialogdlgAbout.DoModal();}else if ((nID & 0xFFF0) == SC_CLOSE){//用户点击右上角"X"EndDialog(IDOK);}else{CDialog::OnSysCommand(nID, lParam);}}方法二：BOOL CTest6Dlg::PreTranslateMessage(MSG* pM sg){if ( pMsg->message == WM_KEYDOWN ){switch(pMsg->wParam){case VK_ESCAPE:return T RUE; //直接返回TRUEbreak;case VK_RET URN:return T RUE;break;}}return CDialog::PreTranslateMessage(pM sg);}方法三：Q122489：How to Disable Default Pushbutton Handling for MFC Dialog/kb/122489/en-us--------------------------------------------------------------------------------14.在对话框中处理键盘鼠标消息处理PreTranslateMessage消息以下代码示例只演示了键盘WM_KEYDOWN消息，你也可以处理鼠标消息，比如WM_LBUTTONDOWN,WM_LBUTTONUP,WM_RBUTTONDOWN等。
