c++ aadding data to a list box vs2005 mfc project

thanks for that i throws up a
c:\c++ aab using visual c++\add list box 2\add list box 2.cpp(68): error C2039: 'AddString' : is not a member of 'ATL::CStringT<BaseType,StringTraits>'

guess i am missing a header file but cannot find what it is any ideas

Hm - maybe I did something wrong ...

I assumed LBlistbox is a member of CSdialog and declared as a CListBox, but from the error you posted it seems it is declared as a CString - in this case my code can't work as it is, you either should change it in a way LBlistbox is declared as a CListBox and bound to the list box via DDX_Control, the other possibility is to retrieve a pointer to the control using GetDlgItem wherever you need it, i.e.:

  ...
  CListBox* pListBox = (CListBox*)GetDlgItem( IDC_LISTBOX );
  pListBox->AddString(...);
...

Select allOpen in new window

I myself prefer the first, because it's easy to do using ClassWizard and there's no need for ugly (because not type-safe) casting from CWnd* to CListBox*.

as you suggested set the dialog box to CListBox  the below loaded all ok but the data does not display
how do i refresh the screen please

     dlg.m_listboxcontrol.AddString( "Item" );
     dlg.m_listboxcontrol.AddString("Biology");
    dlg.m_listboxcontrol.AddString("Accounting");
    dlg.m_listboxcontrol.AddString("Art Education");
    dlg.m_listboxcontrol.AddString("Finance");
    dlg.m_listboxcontrol.AddString("Computer Science");
      int idx = dlg.m_listboxcontrol.AddString( "Selected Item" );
    dlg.m_listboxcontrol.SetCurSel( idx );

Hm ... where do you call this? Doesn't seem to be inside the dialog's OnInitDialog since you use 'dlg.'

As told: It is not possible to fill the list box control directly before DoModal is called.

found the onintdialog section and placed the code in there and it now loads and displays so thanks for that

BOOL Caddlistbox2Dlg::OnInitDialog()
{
      CDialog::OnInitDialog();
      m_listboxcontrol.AddString( "Item" );
      m_listboxcontrol.AddString("Biology");
    m_listboxcontrol.AddString("Accounting");
    m_listboxcontrol.AddString("Art Education");
    m_listboxcontrol.AddString("Finance");
    m_listboxcontrol.AddString("Computer Science");
      int idx = m_listboxcontrol.AddString( "Selected Item" );
    m_listboxcontrol.SetCurSel( idx );

You're welcome, I'm glad I could help,

have a nice day,

best regards,
