Handling ListView Clicks

How can i know if my ListView has a item that have been clicked? Subclassing? If it is subclassing how can i subclass a windows that i did editing a resource?

Thank you

Handling a click is very similar to handling a right click. Here is some sample code. This code goes in the parent's window procedure.

Code:

case WM_NOTIFY:
	lpnmhdr = (LPNMHDR)lParam;

	if(lpnmhdr->hwndFrom == hwndList)
	{
		if(lpnmhdr->code == NM_CLICK)
		{
			LPNMITEMACTIVATE lpnmitem = (LPNMITEMACTIVATE) lParam;
			LVHITTESTINFO    hti      = { 0 };

			hti.pt = lpnmitem->ptAction;
			ListView_HitTest(hListView, &hti);

			if(hti.flags & LVHT_ONITEM)
			{
				TCHAR buf[100];
				wsprintf(buf, TEXT("Item No. %d was clicked."), hti.iItem);
				MessageBox(NULL, buf, NULL, 0);
			}
		}
	}
	break;

Thank you!
