我在工具条上加了个日期控件要保存它哦 m_pXXX

CDateTimeCtrl* pCtrl = m_pXXX...//你怎么建的就怎么得

然后~~调函数

选中ListCtrl中的Checkbox并以高亮显示 void CAlarmType::OnLvnItemchangedTypelist(NMHDR *pNMHDR, LRESULT *pResult) { // TODO: 在此添加控件通知处理程序代码 NM_LISTVIEW* pNMListView=(NM_LISTVIEW*)pNMHDR; if (pNMListView->iItem != -1) { if ((pNMListView->uOldState & INDEXTOSTATEIMAGEMASK(1)) && (pNMListView->uNewState & INDEXTOSTATEIMAGEMASK(2))) { m_lstRole.SetItemState(pNMListView->iItem, LVIS_SELECTED, LVIS_SELECTED); } else if ((pNMListView->uOldState & INDEXTOSTATEIMAGEMASK(2)) && (pNMListView->uNewState & INDEXTOSTATEIMAGEMASK(1))) { m_lstRole.SetItemState(pNMListView->iItem, 0, LVIS_SELECTED); } } *pResult=0; }

afx_msg void OnNMRclickList1(NMHDR *pNMHDR, LRESULT *pResult); // 列表 CListCtrl m_list;

CListCtrl功能的全部应用 void CListDemoDlg::OnLvnBegindragListFolder(NMHDR *pNMHDR, LRESULT *pResult) { if(m_listFolder.GetListType()!=TYPE_PICNOTIP && m_listFolder.GetListType() != TYPE_PICTIP) return; static int i = 0; TRACE("Draging %d\r\n", i++); LVITEM itemInfo; LPNMLISTVIEW pNMLV = reinterpret_cast(pNMHDR); itemInfo.mask = LVIF_IMAGE; itemInfo.iItem = pNMLV->iItem; itemInfo.iSubItem = 0; m_listFolder.GetItem(&itemInfo); DWORD dwState; dwState = m_listFolder.m_arrayItemState.GetAt(pNMLV->iItem); dwState &= ~PICITEMSTATE_MOUSEOVER; dwState |= PICITEMSTATE_DRAG; m_listFolder.m_arrayItemState.SetAt(pNMLV->iItem, dwState); m_listFolder.Invalidate(); m_lvDragItem = *pNMLV; m_lvDragItem.iSubItem = itemInfo.iImage; m_listFolder.ClientToScreen(&m_lvDragItem.ptAction); SetTimer(TIMER_DRAG, 0, 0); *pResult = 0; }

可参考此例使用标签控件，部分代码 void CDemoDlg::OnSelchangeTab(NMHDR* pNMHDR, LRESULT* pResult) { //获得当前标签项 int nSel = m_ctrlTab.GetCurSel(); CString strText = _T(""); strText.Format(_T("Tab %d"), nSel + 1); SetDlgItemText(IDC_EDIT, strText); } void CDemoDlg::InitTab() { //向标签控件中插入项 for (int n = 0 ; n < 5; n++) { CString strText = _T(""); strText.Format(_T("Tab %d"), n + 1); m_ctrlTab.InsertItem(n, strText); } }

Follow these 10 easy steps to build the OutLookRichEdit control: Insert a rich edit control into the dialog. Call AfxInitRichEdit() in the InitInstance of the App class or in InitDialog. If it does not exist, copy OutLookRichEdit.cpp and OutLookRichEdit.h to the project directory. Click the menu choice Project-Add to Project-Files and select the above-copied files to add the wrapper class to your project. Import the hand cursor into the resource and rename it "IDC_LINK". Use Classwizard to add a member variable of the rich edit control (CRichEditCtrl). Include the OutLookRichEdit.h file in the dialog's header file and change the declaration of rich edit member variable, as in CRichEditCtrl m_ctrlText1; to COutLookRichEdit m_ctrlText1; In InitDialog(), add the following code. Post a comment Email Article Print Article Share Articles Digg del.icio.us Newsvine Facebook Google LinkedIn MySpace Reddit Slashdot StumbleUpon Technorati Twitter Windows Live YahooBuzz FriendFeed m_ctrlText1.SetRawHyperText(_T("Click <%$here$#100#%> to see the about box.")); At this level, if you build the project and run it, you can see the rich edit control with linked text, but nothing would happen if you clicked on the link. To Show a dialog while the link is clicked, you have to add some more code in the dialog class. Before that, have a closer look at the preceding code and hypertext syntax. The link text is enclosed between the "$" symbols and the corresponding dialog's resource value 100 (About Box), enclosed in "#" symbols. You can find the #define values of dialogs in the resource.h file. Use ClassWizard to map OnNotify of the dialog and write the corresponding implementation code in .cpp file, like: BOOL CDEMODlg::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult) { NMHDR* pNmHdr = (NMHDR*) lParam; if(IDC_RICHEDIT1 == pNmHdr->idFrom){ switch(pNmHdr->code) { case IDD_ABOUTBOX: CAboutDlg oDlg; oDlg.DoModal (); break; } } return CDialog::OnNotify(wParam, lParam, pResult); } Now, build and run the project. It is recommended that you set the read-only attribute to the rich edit control.
