add items to a list view

Hi,

I am using the following code to create a List View Control:

Code:

---

        // Adding List-View Columns
        TCHAR szText[256] = {0};
        TCHAR szString[5][20] = { TEXT("Column 1"),TEXT("Column 2"),TEXT("Column 3") };

        HWND hlistview = CreateWindowEx(0, WC_LISTVIEW, 0, WS_VISIBLE | WS_CHILD | WS_BORDER | LVS_ALIGNLEFT | LVS_REPORT | LVS_EDITLABELS, 40,90,430,200, hwnd, (HMENU)IDC_LIST1, hInst, NULL);
        SetWindowFont(hlistview,hfont0,TRUE);

        LVCOLUMN lvc;
        ListView_DeleteAllItems(hlistview);

        lvc.mask = LVCF_FMT | LVCF_WIDTH | LVCF_TEXT | LVCF_SUBITEM;

        for (int k = 0; k < 3; k++)
        {
                lvc.iSubItem = k;
                lvc.cx      = 100;
                lvc.pszText  = szString[k];
                lvc.fmt      = LVCFMT_LEFT;

                ListView_InsertColumn(hlistview, k, &lvc);
        }

        // Adding List-View Items and Subitems

        struct petinfo
        {
                TCHAR szKind[10];
                TCHAR szBreed[50];
                TCHAR szPrice[20];
        };

        petinfo pi[] =
        {
                {TEXT("Dog"), TEXT("Poodle"), TEXT("$300.00")},
                {TEXT("Cat"), TEXT("Siamese"), TEXT("$100.00")},
                {TEXT("Fish"), TEXT("Angel Fish"), TEXT("$10.00")}
        };

        LVITEM lvi;
        lvi.mask      = LVIF_TEXT | LVIF_PARAM | LVIF_STATE;
        lvi.state    = 0;
        lvi.stateMask = 0;

        for (int k = 0; k < 3; k++)
        {
                lvi.iItem    = k;
                lvi.iSubItem = 0;
                lvi.lParam  = (LPARAM) &pi[k];
                int res = ListView_InsertItem(hlistview, &lvi);
        }

---

while I get the list view collumn correct I don't get any items...what am I doing wrong?

thanks

Try it something like this instead:

Code:

---

LVITEM lvi;
  memset(&lvi,0,sizeof(LVITEM));
  lvi.mask      = LVIF_TEXT | LVIF_PARAM | LVIF_STATE;
  lvi.state    = 0;
  lvi.stateMask = 0;

  for (int k = 0; k < 3; k++)
  {


    lvi.iItem    = k;
    lvi.iSubItem = 0;
  //lvi.lParam  = (LPARAM) &pi[k];
    int res = ListView_InsertItem(hlistview, &lvi);
    ListView_SetItemText(hlistview,res,0,pi[k].szKind);
    ListView_SetItemText(hlistview,res,1,pi[k].szBreed);
    ListView_SetItemText(hlistview,res,2,pi[k].szPrice);
  }

---

Thank you ever so much!

By the way, do yo think there's any way to add a line between the rows (not that important to me though)

Also, I ma having a lot of compiler errors because of this:

Code:

---

        struct petinfo
        {
                TCHAR szKind[10];
                TCHAR szBreed[50];
                TCHAR szPrice[20];
        };

        std::map<int, petinfo> rows;
       
        {
                petinfo pinfo = { TEXT("Name1"), TEXT("Surname1"), TEXT("Age1") };
                rows.insert( std::make_pair(0, pinfo) );
        }

        {
                petinfo pinfo = { TEXT("Name2"), TEXT("Surname2"), TEXT("Age2") };
                rows.insert( std::make_pair(1, pinfo) );
        }

        std::map<int, petinfo>::const_iterator itt;
       
        LVITEM lvi;
        memset(&lvi,0,sizeof(LVITEM));
        lvi.mask      = LVIF_TEXT | LVIF_STATE;
        lvi.state    = 0;
        lvi.stateMask = 0;

        for(itt=rows.begin(); itt!=rows.end(); ++itt)
        {
                lvi.iItem    = itt._Dec;
                lvi.iSubItem = 0;

                ListView_InsertItem(hlistview, &lvi);

                ListView_SetItemText(hlistview, itt, 0, pinfo[itt].szKind);
                ListView_SetItemText(hlistview, itt, 1, pinfo[itt].szBreed);
                ListView_SetItemText(hlistview, itt, 2, pinfo[itt].szPrice);
        }

---

what am Idoing wrong?

thanks

I am sorry that was my mistake!

Code:

---

        for(itt=rows.begin(); itt!=rows.end(); ++itt)
        {
                lvi.iItem    = itt->first;
                lvi.iSubItem = 0;

                ListView_InsertItem(hlistview, &lvi);

                ListView_SetItemText(hlistview, itt->first, 0, (LPWSTR)itt->second.szBreed);
                ListView_SetItemText(hlistview, itt->first, 1, (LPWSTR)itt->second.szKind);
                ListView_SetItemText(hlistview, itt->first, 2, (LPWSTR)itt->second.szPrice);

        }

I'm not sure what the problem is(was) but you should be consistent with your string macros. If you use the _T() or TEXT() macros, then you should use the tstring versions everywhere:

Code:

---

                ListView_SetItemText(hlistview, itt->first, 0, (LPTSTR)itt->second.szBreed);
                ListView_SetItemText(hlistview, itt->first, 1, (LPTSTR)itt->second.szKind);
                ListView_SetItemText(hlistview, itt->first, 2, (LPTSTR)itt->second.szPrice);
