'Declaration
 
Public Function SetAnnotationTitle( _
   ByVal AnnotationIdx As Integer, _
   ByVal Title As String _
) As GdPictureStatus

public GdPictureStatus SetAnnotationTitle( 
   int AnnotationIdx,
   string Title
)

public function SetAnnotationTitle( 
    AnnotationIdx: Integer;
    Title: String
): GdPictureStatus;

public function SetAnnotationTitle( 
   AnnotationIdx : int,
   Title : String
) : GdPictureStatus;

public: GdPictureStatus SetAnnotationTitle( 
   int AnnotationIdx,
   string* Title
)

public:
GdPictureStatus SetAnnotationTitle( 
   int AnnotationIdx,
   String^ Title
)

Parameters

AnnotationIdx: The 0-based index of the required annotation within the current page. It must be a value from 0 to GetAnnotationCount-1.
Title: The new title of the specified annotation object.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.

We strongly recommend always checking this status first.

Remarks

This method is only allowed for use with non-encrypted documents.

Likewise always ensure that you have selected the correct page using the SelectPage method before applying an annotation index.
