This operation destroys an ImageList. Normally this will be an ImageList created by the WBITMAP-LOAD-IMAGELIST operation, but it may be any ImageList that resides on the desktop machine. When running under the thin client, the ImageList is destroyed on the desktop machine. This operation takes a single parameter, the handle of the ImageList to destroy. This should be USAGE COMP-5. Because the runtime cannot verify this parameter, you should take extra care to ensure that it is valid.
