Comments
If the used object is not Created, the annotation cursors are changed for all the automation objects that will be created from this point on. It also changes the cursors for the automation objects that have not had their cursors changed (still using defaults).
If the used object is Created, the hCursor is changed only for the specified automation object. Some programs create a new automation object each time a file is opened. This is especially true for MDI applications. In this case, the hCursor is set only for the current file. If you want this hCursor to be set for all files, you must set the hCursor each time you create a new automation object, or call LAnnAutomation::SetAutoCursor with hObject set to NULL.
Internally, a copy is made of hCursor, so the hCursor can be destroyed after calling this fuction.
To retrieve a copy of an annotation cursor, call LAnnAutomation::GetAutoCursor.
