This article was previously published under Q73667 SUMMARY
An application can use the CreateCursor() and CreateIcon() APIs
to create icons and cursors on the fly. The application determines
the shape at run time.
When the shape of the icons and the cursors is known in advance, an
application should use LoadIcon() and LoadCursor().
An application that uses CreateIcon() must call DestroyIcon() to free the
memory used by the icon when it is no longer needed. An application that
uses CreateCursor() must call DestroyCursor() to release the memory used by
the cursor when it is no longer needed.
An application can call DestroyIcon() and DestroyCursor() only when the
icon or the cursor is not in use. For example, if the cursor created by
CreateCursor() has been specified in a SetCursor call, it must not be
destroyed until it has been released by another SetCursor() call.
An application can only use DestroyIcon() and DestroyCursor() to destroy
icons and cursors created by CreateIcon() and CreateCursor(). It should not
try to destroy icons and cursors loaded with LoadIcon() and LoadCursor().
