hi,I need your help......

what's the difference between file->new and window->newwindow in MDI project(pj name mydoc)? why use file->new, the newfile name is mydoc1(or mydoc2,mydoc3,mydoc4.......) but window->new Window, the new doc name is mydoc1:2 (or mydoc1:3, mydoc1:4, mydoc2:2.......)?

have you add the #include "resource.h" in you application? in fact, these resource are defined in resource.h.

Dear VC-master, Thank you for your attention, In my MDI project, the based view is CFormView. named CMyView. the problem is, in CMainFrame class, SetValue()was defined. in CMyView class, public function SetEdit(true)was defined. in myview.cpp, if I use below, it is ok. void CMyView::OnSendValue() { CMainFrame *pMainfram = (CMainFrame *)AfxGetMainWnd(); pMainfram->SetValue(0x55); } but if In MainFrm.cpp void CMainFrame ::OnSendValue() { CMyView *pMyView= (CMyView *)GetActiveView(); pMyView->SetEdit(true); } it can build successfully, but failed execute. how to call the function/variable in active view?

you can find the CRecordset in the web... it can open the excel as database void CExDlg::OnRead() { // TODO: Add your control notification handler code here CDatabase database; CString sDriver; CString sDsn; CString sFile,sPath; //find the excel in main exe folder GetModuleFileName(NULL,sPath.GetBufferSetLength (MAX_PATH+1),MAX_PATH); sPath.ReleaseBuffer (); int nPos; nPos=sPath.ReverseFind ('\\'); sPath=sPath.Left (nPos); sFile = sPath + "\\Demo.xls"; //name of excel sDsn.Format("ODBC;DRIVER={%s};DSN='';DBQ=%s", sDriver, sFile); TRY { database.Open(NULL, false, false, sDsn); CRecordset recset(&database); CString sSql; sSql = "SELECT item FROM Regt WHERE item = 'iwant' "; // // exe SQL recset.Open(CRecordset::forwardOnly, sSql, CRecordset::readOnly); BYTE line = 1; // »ñÈ¡²éѯ½á¹û while (!recset.IsEOF()) { //¶ÁÈ¡ExcelÄÚ²¿ÊýÖµ recset.GetFieldValue("item", sitem); // read out the item line++; //ÏÔʾ¼ÇÈ¡µÄÄÚÈÝ m_listbox.AddString( sitem); // ÒƵ½ÏÂÒ»ÐÐ recset.MoveNext(); } // close database.Close(); } CATCH(CDBException, e) { // Êý¾Ý¿â²Ù×÷²úÉúÒ쳣ʱ... AfxMessageBox("error: " + e->m_strError); } END_CATCH; }

I tried, and failed...... if there is no better methord,I would have to add the edit proc function in PreTranslateMessage() directly...

yes the code below else is where I need your kindly help. if (!GetFocus()->IsKindOf(RUNTIME_CLASS(CEdit))) return true;// do nothing and ignore the key process else { ............... //add proper code for EDIT control capture the Enter and ESC key. }

thank you for you suggestion, Ceric Moonen suggested me also. now the problem is how do single-line Edit control capture the Enter/Esc key.

then, how to handle the enter/esc key for Edit control and buttons? And seems that it doesn't enter into the OnChar() at all.

GetFocus()->IsKindOf(RUNTIME_CLASS(CEdit)) is for checking current focus on Edit control or not. if it is not on edit control, will return and do nothing,if the focus is on edit control, then do what I want to.... -- modified at 4:35 Tuesday 20th June, 2006 By returning true from PreTranslateMessage(...), you are telling your application to bypass any default handling of the message. yes, or it will close the dialog

My edit controls are single-line. in fact, what I want is send a message to Parent window, when the focused edits/buttons get Enter/ESC key.

Surely, the Dialog will close when the Enter and ESC key down. I know reload the PreTranslateMessage(MSG* pMsg) function can avoid the problem. In my project, there are some other controls in the dialog, and I want the Edit controls and buttons can get the Enter/ESC command but not close the Dialog, is there any way? I tried the OnChar(), OnCommad(), there din't work at all. BOOL CEditDlg::PreTranslateMessage(MSG* pMsg) { // TODO: Add your specialized code here and/or call the base class if(pMsg->message==WM_KEYDOWN) { if(pMsg->wParam==VK_RETURN || pMsg->wParam==VK_ESCAPE) { if (!GetFocus()->IsKindOf(RUNTIME_CLASS(CEdit))) return true;// pMsg->wParam=NULL ; else { ............... } } } return CDialog::PreTranslateMessage(pMsg); }

it was impossible that my project would use over 10KB memory...... if I delete the debug folder, and rebuild the project, it seems ok, if I continue to add some class or variable for MFC controls, the error occurs again. some times the error is "Assert" some times is other.....
