}

break;

// Handle this notify if you want to use the number keys to select

// items in the view (like how the desktop file explorer lets you

// select files by typing the first few characters of the file name.)

// This notify is also used then the control is sent an LVM_FINDITEM

NMLVFINDITEM* pFindItem = (NMLVFINDITEM*)lParam;

// Used if you are trying to find an item in the list view
