            if (hWndListView == NULL)
                        MessageBox(hwnd,"Oooops","",MB_OK);

Well, your MessageBox doesn't make any sense.
From MSDN (CreateWindow Function):

If the function fails, the return value is NULL. To get extended error information, call GetLastError.

While I am new to vc++ myself, I have created a listview control.

try to see if your input handle to hwnd is valid.

make sure h your instance handle is valid.

I would remove some of the styles and see what you get.

here is some code I used in my program
hTemp = CreateWindow(WC_LISTVIEW, L"List", WS_CHILD | WS_VISIBLE | LVS_REPORT , 45 + 35, 148 + 122, 240, 110, hDlg, (HMENU)Direct_List_ID, hInst, NULL);

//note: Direct_List_ID is useful if you plan on making reference to the control later in receiving notification messages.

if all else is lost refer to the source for listviews

Appropriate InitCommonControlsEx call is required prior to create common controls.
