From: Leandro Delamare on 16 Feb 2005 14:21 Hello Friends I add some values to my treeview, but now I want to write the selected value in a EDIT BOX, how can I do this ? is in the item bellow correct ? but what the command to get the value of selected item ? Regards Leandro void CTeste1Dlg::OnTvnItemexpandedTree1(NMHDR *pNMHDR, LRESULT *pResult) { LPNMTREEVIEW pNMTreeView = reinterpret_cast<LPNMTREEVIEW>(pNMHDR); // TODO: Add your control notification handler code here *pResult = 0; CTreeCtrl* pCtrl = (CTreeCtrl*) GetDlgItem(IDC_TREE1); ASSERT(pCtrl != NULL); SetDlgItemText(IDC_EDIT1,??); }
From: AliR on 16 Feb 2005 13:36 Look in the help! I would say that you should catch the TVN_SELCHANGED message, this notify message will get sent to you when an item is selected. something like this void CMyDlg::OnTvnSelchangedTree1(NMHDR *pNMHDR, LRESULT *pResult) { LPNMTREEVIEW pNMTreeView = reinterpret_cast<LPNMTREEVIEW>(pNMHDR); // TODO: Add your control notification handler code here CString Temp = m_Tree.GetItemText(pNMTreeView->itemNew.hItem); *pResult = 0; } you can also call GetSelectedItem at any point to get the tree's selected item HTREEITEM hItem = m_Tree.GetSelectedItem(); if (hItem != NULL) { Temp = m_Tree.GetItemText(hItem); } AliR.

From: Ajay Kalra on 16 Feb 2005 13:49 You can use GetSelectedItem() to get the item that is currently selected in your treeview. --------- Ajay Kalra ajaykalra(a)yahoo.com

From: Joseph M. Newcomer on 16 Feb 2005 16:26 Lose the GetDlgItem. I don't know why everyone in sight uses GetDlgItem, but this is the third time today I've had to point this out. Create a control member variable for each control. See my essay on avoiding GetDlgItem. Also, it is a very good idea to change those stupid names assigned by the dialog editor to something that make sense. IDC_EDIT1 is useless. Give it a real name. Then create a control variable with a meaningful name., I've used c_MyTree and c_MyEdit although sensible names should be used to indicate what these mean. HTREEITEM item = c_MyTree.GetSelectedItem(); if(item == NULL) return; // we should never gotten here... CString text = c_MyTree.GetItemText(item); c_MyEdit.SetWindowText(text); joe On Wed, 16 Feb 2005 16:21:37 -0300, "Leandro Delamare" <lhdelamare(a)uol.com.br> wrote: >Hello Friends > >I add some values to my treeview, but now I want to write the selected value >in a EDIT BOX, how can I do this ? > >is in the item bellow correct ? but what the command to get the value of >selected item ? > >Regards >Leandro >void CTeste1Dlg::OnTvnItemexpandedTree1(NMHDR *pNMHDR, LRESULT *pResult) > >{ > >LPNMTREEVIEW pNMTreeView = reinterpret_cast<LPNMTREEVIEW>(pNMHDR); > >// TODO: Add your control notification handler code here > >*pResult = 0; > >CTreeCtrl* pCtrl = (CTreeCtrl*) GetDlgItem(IDC_TREE1); > >ASSERT(pCtrl != NULL); > > >SetDlgItemText(IDC_EDIT1,??); > >} > Joseph M.
