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.
