GdPicture14 Namespace / AnnotationManager Class / GetFirstAnnotationCommentIdx Method

GetFirstAnnotationCommentIdx Method (AnnotationManager)

In This Topic
Returns an index of the first GdPicture/XMP comment annotation, if any exists, that is attached to a GdPicture/XMP annotation object specified by its index related to the selected page of the document currently handled by this AnnotationManager object.

Be aware that this method only handles GdPicture/XMP annotations. Likewise, annotations are always treated relative to the selected page.

Syntax
'Declaration

 

Public Function GetFirstAnnotationCommentIdx( _

   ByVal AnnotationIdx As Integer _

) As Integer
public int GetFirstAnnotationCommentIdx( 

   int AnnotationIdx

)
public function GetFirstAnnotationCommentIdx( 

    AnnotationIdx: Integer

): Integer; 
public function GetFirstAnnotationCommentIdx( 

   AnnotationIdx : int

) : int;
public: int GetFirstAnnotationCommentIdx( 

   int AnnotationIdx

) 
public:

int GetFirstAnnotationCommentIdx( 

   int AnnotationIdx

) 

Parameters

AnnotationIdx
The 0-based index of the required annotation within the selected page of the handled document. It must be a value from 0 to GetAnnotationCount-1.

Return Value

An index of the first GdPicture/XMP comment annotation, if exists, that is attached to the GdPicture/XMP annotation according to the given index. The GetStat method can be subsequently used to determine if this method has been successful.

The returned value is between 0 and GetAnnotationCount-1 if the annotation with the given index includes a comment annotation, or -1 if no comment annotation is attached to the given annotation.

Remarks
Please ensure that the returned value is valid annotation index, which means it is greater then -1, before using it further.

Be aware that annotations are always treated relative to the selected page.
