c++ winapi listview item selected but not highlighted

Question

here is the dialogProc for my dialog box that contains the listview the dialog is created by a simple button from the main window of my application . the problem is ListView_SetItemState succeeds but the item is not highlighted . also when i manually click an item (icon) only the icon is selected (highlighted) not the entire RECT of the item. thanks for your help.

   BOOL CALLBACK DialogProc(HWND ihDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)
   {
   TCHAR pszfile[MAX_PATH];
   SIZE  size;
   int   selected_icon,wn_v;

Use the LVS_SHOWSELALWAYS window style if you want the selection to be shown even if the Listview does not have the focus.

Use the LVS_EX_FULLROWSELECT window extended style if you want item AND sub-item highlighted when selected.

Use CreateWindowEx , or SetWindowLong with GWL_EXSTYLE , to be abble to specify the extended style.
