You can make an existing drawing note unselectable by users if you wish to protect it from modification. The functions
ProDtlnotedataReadonlySet() and
ProDtlnotedataReadonlyGet() set and get this property on
ProDtlnotedata objects. Use function
ProDtlnotedataReadonlySet() in conjunction with
ProDtlnoteDataGet() and
ProDtlnoteModify() to change the setting.
The function
ProDrawingReadonlyselectionAllow() will temporarily allow the selection of read-only notes.
