ListBox - easy one
Hi
I have a pop up dialog box that contains a list box which displays a number of strings the user can select before clicking the OK button to close the dialog. How do I get and store the string the user selected?
Thanks

Try this:
CString str;
int Index = m_list.GetCurSel();
if ( Index != LB_ERR )
m_list.GetText(Index,str);
Cheers

Maintain a cur sel member variable in the dialog box class , something like
class CYourDialog : public CDialog
{
...
public:
int m_nCurSel;
}
In OnOK handler, set it, as golanshahar suggests
void CYourDialog::nOK()
{
m_nCurSel = m_oListBox.GetCurSel();
CDialog::OnOk();
}
After DoModal, check the value like below
CYourDialog oDlg;
if(IDOK == oDlg.DoModal())
{
//oDlg.m_nCurSel
}

Thanks for the help but I still can't get this to work:
BOOL CInstrumentDlg::OnInitDialog()
{
...
pLB = (CListBox*)GetDlgItem(IDC_LIST_INSTRUMENT);
pLB->InsertString(-1, "Drums");
pLB->InsertString(-1, "Electric Guitar");
pLB->InsertString(-1, "Acoustic Guiatr");
pLB->InsertString(-1, "Bass");
pLB->InsertString(-1, "Snare");
}
void CInstrumentDlg::OnOK()
{
//get selected instrument and store it in a String
CString m_nCursorSel;
m_nCursorSel = pLB->GetCurSel();
CDialog::OnOK();
}
What am I doing wrong?
Thanks

Aside from not using the DDX mechanism
please don't use the m_ prefix for local variable. That denotes a class member.
Also, if you're going to use Hungarian notation, use it properly. n denotes an integer. A variable beginning with m_n would be expected to be an int member of the class.
pLB->GetText(pLB->GetCurSel(), m_nCursorSel);
