The following constants are used in the WM_LTANNEVENT message when wParam is LTANNEVENT_AUTOITEMCHANGING. In this case, lParam points to a structure of type ANNCHANGEPARAM, and the uChange fields is a constant from the following list.

In the comment below, the first word is a description of the annotation property that is changed. If there is a reference to an LAnnXXXX function, see the documentation of the function for a complete description of the property.

Please note that formerly ANNCHANGE_DELETE had the value [0] and ANNCHANGE_ROTATE had the value [1].
