Comments
This message will insert the specified item at the specified index in the list. All items from the specified index are pushed up by one.
You must set the uStructSize member of the LILSELOPTION structure before using this message.
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.
The associated macro is:
L_ImgListInsertAt(hWnd, uIndex, pItem)
For a complete list of available macros, refer to the Ltlst.h file.
