Inserts an item into the ImageList Control.

Parameter

Description

pItem

Pointer to an LILITEM structure containing the item to be inserted.

nIndex

0-based index at which to insert the item. Pass -1 to insert item at the end of the list.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

All items beyond the specified index are pushed up by one.

Note: On an insert, the image and text (if any) are copied to internal storage. The ImageList Control will free its copy of the image and/or text when the item is deleted. You are responsible for freeing the original data when it is no longer needed by your application.
