The WM_VKEYTOITEM message is sent by a list box with the LBS_WANTKEYBOARDINPUT
style to its owner in response to a WM_KEYDOWN message.
WM_VKEYTOITEM
- key = LOWORD(wParam); // virtual-key code
nCaretPos = HIWORD(wParam); // caret position
hwndLB = lParam; // handle of list box
Parameters
Value of the low-order word of wParam. Specifies the virtual-key code of the key the user pressed.
nCaretPos
Value of the high-order word of wParam. Specifies the current position of the caret.
hwndLB

Return Values
The return value specifies the action that the application performed in
response to the message. A return value of  2 indicates that the application handled all aspects of selecting the item and
requires no further action by the list box. A return value of 1 indicates that the list box should perform the default action in response to
the keystroke. A return value of 0 or greater specifies the index of an item
in the list box and indicates that the list box should perform the default
action for the keystroke on the given item.
