ListView_InsertItem is failing!

Code:

---

int DumpCompiler(HWND hwnd, char *pStr) {
        LVITEM item = {0};
        item.mask = LVIF_TEXT;
        item.pszText = pStr;
        item.iItem = ListView_GetItemCount(hwnd);
        ListView_InsertItem(hwnd, &item);
    return ListView_EnsureVisible(hwnd, item.iItem, 0);
}

---

This is how I create the ListView

Code:

---

INITCOMMONCONTROLSEX iccx;
                        iccx.dwSize = sizeof(INITCOMMONCONTROLSEX);
                        iccx.dwICC = ICC_BAR_CLASSES|ICC_LISTVIEW_CLASSES;
                        InitCommonControlsEx(&iccx);

hCompiler = CreateWindowEx(WS_EX_CLIENTEDGE, WC_LISTVIEW, NULL, WS_CHILD|WS_VISIBLE|LVS_REPORT|LVS_SINGLESEL|LVS_NOCOLUMNHEADER|LVS_SORTDESCENDING, 5, 280, 0, 0, hWnd, HMENU(IDC_COMPILER), hInstance, 0);
                        ListView_SetBkColor(hCompiler, RGB(0,0,0));
                        ListView_SetTextColor(hCompiler, RGB(0,255,0));
                        ListView_SetTextBkColor(hCompiler, RGB(0,0,0));

When I use:

Code:

---

DumpCompiler(hCompiler, "Hola");

---

Nothing happens...any ideas?

Usually when a window won't respond and I think it should, it's because the window hasn't actually finished being created yet. CreateWindowEx() only guarantees that the window will be created at some point in the future -- it will return before the window has finished initializing.

Did you notice your listview has height and width 0?

Edit: There's another problem too. You're using the LVS_REPORT style which requires the listview to have columns. Try inserting a column (or removing that style):

Code:

---

LVCOLUMN lvc = {0};
lvc.mask = LVCF_WIDTH;
lvc.cx = 200; //or whatever column width you want
ListView_InsertColumn(hCompiler,0,&lvc);

I think JaWiB has the solution.

You may also be interested in this list-view sample.

Ok, I'll check the link, but I'd like to add lines like the listbox, but the idea of using listview is that I can change in runtime the fore and back color.

Add the extended style

LVS_EX_GRIDLINES
