Solution 1

Add an LBN_SELCHANGE[^] handler to your dialog class that updates the edit control with the newly selected item:

C++

CMyDialog::OnSelChange()
{
    int nSel = m_ListBox.GetCurSel();
    if (nSel != LB_ERR)
    {
        CString strText;
        m_ListBox.GetText(nSel, strText);
        m_EditBox.SetWindowText(strText);
    }
}

SetText is not working.!!
Please provide a sample program..

Jochen Arndt 9-Mar-15 7:11am

Sorry. Must be SetWindowText of course.

Member 11493554 9-Mar-15 7:25am

SetWindowText is also not working

Jochen Arndt 9-Mar-15 7:31am

I just checked it here and it is working for me.
Is your handler called (check it by setting a breakpoint)?

If not, you must set the LBS_NOTIFY style for your list box as noted in the MSDN entry for LBN_SELCHANGE (see the link from my answer).

Note also that the handler is not called if you set the selection programmatically (e.g. with SetCurSel).

Im using CIniFile Class method

Jochen Arndt 9-Mar-15 7:52am

I don't see the relation of that class (there are multiple classes with that name according to Google) to CListBox.

I'm sorry, but:
1. This is not related to your original question.
2. You will not get complete code on this site upon request. This site is for helping on specific problems and providing articles. All who contribute here are volunteers without getting paid.

Your assignment looks like for commercial purposes. So why should anybody here do your job (for which you probably get paid)? Even if it isn't commercial you should try to do it yourself. That together with a lot of reading is the way to become a software developer. If you got stuck on specific parts, we will be glad to help.
