hi to all,
I have to display values in Listview control using ALT. I tried with ListView_InsertColumn to add column header. It got displayed in listview. Where as when i tried to display a corresponding item using ListView_InsertItem to the list view control, I could't able to display it. Can any one suggest me how to display listview control in ATL if there is other way of doing so. The following is the code i have used.

HWND lvwhwnd;
lvwhwnd = m_ctlSysListView32.Create(m_hWnd, rc,_T("hello List View Control"), WS_TABSTOP | WS_CHILD | WS_BORDER | WS_VISIBLE | LVS_AUTOARRANGE |LVS_REPORT | LVS_OWNERDATA,WS_EX_CLIENTEDGE, IDR_LISTVIEW);

LV_COLUMN   lvColumn;
char*     szString;
szString="PAGE URL";
lvColumn.mask = LVCF_FMT | LVCF_WIDTH | LVCF_TEXT | LVCF_SUBITEM;
lvColumn.fmt = LVCFMT_LEFT;
lvColumn.cx = 200;

lvColumn.pszText = szString;
int val = ListView_InsertColumn(lvwhwnd, 0, &lvColumn);
LV_ITEM lvitem;
lvitem.mask = LVIF_TEXT;
//lvitem.iItem     = 0;
//lvitem.iSubItem=0;
lvitem.pszText="My";
int han=ListView_InsertItem(lvwhwnd,&lvitem);
eagerly waiting for advise,
Thanks in advance,
ravi.

Hi!
here is working example (in the DIALOG)

     RECT          rc;
     LV_COLUMN     lvc;
     char          szCaption[48];
     ::GetClientRect(m_hwndList, &rc);
     LoadString(_Module.GetModuleInstance(), IDS_TEMPLATE, szCaption, sizeof(szCaption));

     lvc.mask = LVCF_TEXT | LVCF_WIDTH |LVCF_SUBITEM |LVCF_FMT;
     lvc.cx = 2*rc.right/5-2;
     lvc.pszText = szCaption;
     lvc.fmt = LVCFMT_LEFT | LVCFMT_IMAGE;
     lvc.iSubItem = 0;
     ListView_InsertColumn(m_hwndList, 0, &lvc);

     LoadString(_Module.GetModuleInstance(), IDS_CREATE_DATE, szCaption, sizeof(szCaption));
     lvc.cx = rc.right/5;
     lvc.fmt = LVCFMT_CENTER;
     lvc.iSubItem = 1;
     ListView_InsertColumn(m_hwndList, 1, &lvc);

     LoadString(_Module.GetModuleInstance(), IDS_CHECK_CAPTION, szCaption, sizeof(szCaption));
     lvc.iSubItem = 2;
     ListView_InsertColumn(m_hwndList, 2, &lvc);

     LoadString(_Module.GetModuleInstance(), IDS_SEND_CAPTION, szCaption, sizeof(szCaption));
     lvc.iSubItem = 3;
     ListView_InsertColumn(m_hwndList, 3, &lvc);

// insert items
          LV_ITEM lvi;
          lvi.mask = LVIF_TEXT|LVIF_IMAGE|LVIF_PARAM|LVIF_STATE;
          lvi.iItem = 0;
          lvi.iSubItem = 0;
          lvi.pszText = "code";
          lvi.state = nCount == 1 ? LVIS_SELECTED : 0;
          lvi.stateMask =     LVIS_SELECTED;
          lvi.iImage = 1;
          lvi.lParam = 0;
          ListView_InsertItem(hList, &lvi);
         
          lvi.mask = LVIF_TEXT;
          lvi.iSubItem = 1;
          lvi.pszText = "subitem 1";
          ListView_SetItem(hList, &lvi);
         
          lvi.iSubItem = 2;
          lvi.pszText = "subitem 2";
          ListView_SetItem(hList, &lvi);

Hi,
even i tried with this code, I could able to display the columm headings but the values are not getting displayed.
when i tried
int nval = ListView_InsertItem(hList, &lvi);
A value 0 is getting stored in nval. In documentaion it was
given that it returns a value if inserted else -1 will be returned. Please correct me if i'm wrong. Help me with alternative.
