Comments
This message will insert the specified item at the end of the list.
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_ImgListInsert(hWnd, pItem)
For a complete list of available macros, refer to the Ltlst.h file.
