CWnd::OnCharToItem

afx_msgintOnCharToItem(UINTnChar**,CListBox*pListBox,UINTnIndex);**

Return Value

The framework calls this member function  to specify the action that the application performed in response to the call. 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 zero-based 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.

Parameters

nChar

Specifies the value of the key pressed by the user.

pListBox

Specifies a pointer to the list box. It may be temporary.

nIndex

Specifies the current caret position.

Remarks

Called when a list box with the LBS_WANTKEYBOARDINPUT style sends its owner a message in response to a WM_CHAR message. 

Note   This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
