Comments
This message will remove the specified item from the list.
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_ImgListRemove(hWnd, uIndex)
For a complete list of available macros, refer to the Ltlst.h file.
