Comments
To retrieve the character string for a menu item or dialog box item, use L_AnnGetAutoTextLen to determine the length of the string and to allocate a buffer of appropriate size. Then call L_AnnGetAutoText to retrieve the string.
When you call L_AnnSetAutoText, if you pass an empty string, the menu item defined by uItem will be disabled and removed from the automation menu. To re-enable the menu item, call L_AnnSetAutoText and pass a valid string.
If hObject is NULL, the automation strings are changed for all the automation objects that will be created from this point on. It also changes the strings for the automation objects that have not overwritten the specified string.
If hObject is not NULL, the string is overwritten 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 string is set only for the current file. If you want this string to be set for all files, you must set the string each time you create a new automation object, or call L_AnnSetAutoText with hObject set to NULL.
To reset a string used in the annotation toolbar menus, you must call L_AnnSetAutoText with hObject sett to NULL, since the annotation toolbar is not tied to a specific automation object.
