Hi,

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

////////////////////////////////////////////

// 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

You're not setting the text of each item:

lvi.pszText = pi[k].szKind;

>   int res = ListView_InsertItem(hlistview, &lvi);

And I'm guessing you'll want to set the text for the subitems too:

ListView_SetItemText(hlistview, k, 1, pi[k].szBreed);
ListView_SetItemText(hlistview, k, 2, pi[k].szPrice);

Ok, thanks! So, do you think I could just get rid of the "lvi.lParam" as
well as just using "LVIF_TEXT | LVIF_STATE" in lvi.mask?

By the way, do you think there is any way to put some lines in between
rows??

Sure, if you have no intention of using lParam, then there's no need
to set it. The ListView certainly doesn't care what you do with it.

Call ListView_SetExtendedListViewstyleEx with LVS_EX_GRIDLINES.

Ok. is there any differences between:

ListView_SetExtendedListViewStyleEx(hlistview, 0, LVS_EX_GRIDLINES);

and

ListView_SetExtendedListViewStyleEx(hlistview, LVS_EX_GRIDLINES,
LVS_EX_GRIDLINES);
