◄CWnd► ◄Up► ◄Contents► ◄Index► ◄Back► ──Microsoft Foundation Classes────────────────────────────────────────────── afx_msg int OnVKeyToItem( UINT nKey, CWnd* pListBox, UINT nIndex ); Parameter Description <nKey> Specifies the virtual-key code of the key that the user pressed. <pListBox> Specifies a pointer to the list box. The pointer may be temporary. <nIndex> Specifies the current caret position. Remarks If the CWnd owns a list box with the ◄LBS_WANTKEYBOARDINPUT► style, the list box will send the WM_VKEYTOITEM message in response to a WM_KEYDOWN message. This message-handler member function calls the ◄Default► member function. Override this member function in your derived class to handle the ◄WM_VKEYTOITEM► message. 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 wants 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.
