* Bitmap Resources must be detached from the selected DC when released.

% When the menu is lost focus and window no longer association or the application is occupied, the resource must be released.

The @ DC must be associated with the bitmap that must be associated with it (selected) before being released.

# If the character is specified, the bitmap must be released.

& To deleteObject calls will not destroy regular stockObjects (system internal resource)
