You have to handle the LBN_SELCHANGE notification of this listbox.
Then you call CListBox::GetCurSel method to obtain the index of new selected item and if it not LB_ERR then call CListBox::GetText to obtain the text. now you'll be able to set this text to an edit control.

select item from listbox and diplay into editbox in mfc vc++
Anyway you have to first read MSDN about CListCtrl class, its methods and notifications...
Your post is titled 'select item from listbox and display into editbox..' :confused:Quote:
If you want some info about using list control with MFC have a look at

please post code if possible.
What is nItemIndex? Where and how is it defined/initialized?Quote:
Have you already read MSDN about CListCtrl and its using?Quote:
THERE is a lot of examples out there:

Yes I didQuote:

while (p)
{
int nSelected = m_klist.GetNextSelectedItem(p);
// Do something with item nSelected
}
Then please rectify that code.Quote:

Something like (not tried)
Code:void Cselect_product::OnClickListCategory(NMHDR* pNMHDR, LRESULT* pResult)
{
POSITION p = m_klist.GetFirstSelectedItemPosition();
while (p)
{
int nItemIndex = m_klist.GetNextSelectedItem(p);

DWORD cchBuf(1023);
LVITEM lvi;
lvi.iItem = nItemIndex;
lvi.iSubItem = 0;
lvi.mask = LVIF_TEXT;
lvi.pszText = szBuffer;
lvi.cchTextMax = cchBuf;
if (m_klist.GetItem(&lvi)) {
//use szBuffer here
} else
OutputDebugString("Error with GetItem\n");

Where(in which veriable) is text stored of select item in list control ?Quote:

pszText
Type: LPTSTR
If the structure specifies item attributes, pszText is a pointer to a null-terminated string containing the item text.
So szBuffer will contain the text after a successful call to .getItem()
What List Control notification do you handle?Quote:
Since this is an MFC application then one can use CListCtrl::GetItemText method.Quote:

I got the solution using following code means I got the text of selected value.Quote:
void Cselect_product::OnItemchangedListCategory(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
// TODO: Add your control notification handler code here
CListCtrl* pListCtrl = (CListCtrl *) GetDlgItem(IDC_ListCategory);
POSITION pos = m_klist.GetFirstSelectedItemPosition ();
if (pos == NULL)
TRACE0 ("No items were selected! \n");
else
{
while (pos)
{
int nItem = m_klist.GetNextSelectedItem (pos);
TRACE1 ("Item %d was selected! \n", nItem);
//you could do your own processing on nItem here
strText = m_klist.GetItemText(nItem, 0);
}
}
*pResult = 0;
}
but list control's view property is set to the List at that time I want all this operation when view property of list control is Report.
1. Again: please, use code tags and avoid multiple empty lines! :mad:
2.Why do you call GetDlgItem? :confused:Quote:
You don't need it at all! Just because you already have the control member variable for this list control: m_klist.
3.Then eithe rset it to Report in the resource editor or change the style to LVS_REPORT. See this thread.Quote:
As Victor stated in post #25, pNMListView and pListCtrl are not required here as you are using m_klist and are thus this is superfluous code. Your effective code is
This assumes that the variable strText is either global or a member of the class - and that m_klist has the correct value.Code:void Cselect_product::OnItemchangedListCategory(NMHDR* pNMHDR, LRESULT* pResult)
{
POSITION pos = m_klist.GetFirstSelectedItemPosition();
if (pos == NULL)
TRACE0("No items were selected! \n");
else
while (pos)
{
int nItem = m_klist.GetNextSelectedItem(pos);
TRACE1("Item %d was selected! \n", nItem);
//you could do your own processing on nItem here
strText = m_klist.GetItemText(nItem, 0);
}
*pResult = 0;
}
