GetEmbeddedFileTitle Method (GdPicturePDF)

In This Topic

Gets the title of an embedded file (the title of an attached file) within the currently loaded PDF document. You need to specify this attachment by its 0-based index.

Syntax

Visual Basic
C#
Delphi
JScript
Managed Extensions for C++
C++/CLI

'Declaration
 
Public Function GetEmbeddedFileTitle( _
   ByVal FileIdx As Integer _
) As String

public string GetEmbeddedFileTitle( 
   int FileIdx
)

public function GetEmbeddedFileTitle( 
    FileIdx: Integer
): String;

public function GetEmbeddedFileTitle( 
   FileIdx : int
) : String;

public: string* GetEmbeddedFileTitle( 
   int FileIdx
)

public:
String^ GetEmbeddedFileTitle( 
   int FileIdx
)

Parameters

FileIdx: The 0-based index of the embedded file. It must be a value from 0 to GdPicturePDF.GetEmbeddedFileCount-1.

Return Value

The title of the embedded file. The GdPicturePDF.GetStat method can be subsequently used to determine if this method has been successful.

Mostly it is the whole file name of the embedded file with the file extension. If your files have been embedded using the GdPicturePDF.EmbedFile method, the return value is only the file name of the embedded file without the file extension.

Remarks

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

It is recommend to use the GdPicturePDF.GetStat method to identify the specific reason for the method's failure, if any.

Example

VB.NET

Dim caption As String = "Example: GetEmbeddedFileTitle"
Dim gdpicturePDF As New GdPicturePDF()
If gdpicturePDF.LoadFromFile("TestPDFWithAttachment.pdf", False) = GdPictureStatus.OK Then
    Dim embeddedFileCount As Integer = gdpicturePDF.GetEmbeddedFileCount()
    If gdpicturePDF.GetStat() = GdPictureStatus.OK Then
        If embeddedFileCount = 0 Then
            MessageBox.Show("This PDF file does not contain embedded files.", caption)
        Else
            Dim title As String = gdpicturePDF.GetEmbeddedFileTitle(0)
            Dim status As GdPictureStatus = gdpicturePDF.GetStat()
            If status = GdPictureStatus.OK Then
                MessageBox.Show("The file title of the first embedded file is: " + title, caption)
            Else
                MessageBox.Show("The GetEmbeddedFileTitle() method has failed with the status: " + status.ToString(), caption)
            End If
        End If
