The JournalReader class enables you to load a Journal document stream and to receive an XML stream representing the contents. You can reconstitute, display, and manipulate the ink.
Example
The following Microsoft Visual Basic® .NET example of a handler for a Click event creates an instance of the JournalReader class and uses it to read an existing Journal file.
Note
The DisplayXml method called from this example is not shown. The specific implementation of such a method is dependent on your application's needs.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles Button1.Click
Dim jntStream As Stream
Dim xmlStream As Stream
Dim jntReader As New Microsoft.Ink.JournalReader()
Dim openFileDialog1 As New OpenFileDialog()
' Get the filename from the user by using a File Open dialog
openFileDialog1.InitialDirectory = "C:\"
openFileDialog1.Filter = _
"Journal files (*.jnt)|*.jnt|All files (*.*)|*.*"
openFileDialog1.FilterIndex = 1
openFileDialog1.RestoreDirectory = True
If openFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
Try
jntStream = openFileDialog1.OpenFile()
' Read in the Journal file
xmlStream = jntReader.ReadFromStream(jntStream)
' Show the results
DisplayXml(xmlStream)
Catch ex As Exception
Debug.WriteLine(ex.Message)
Finally
' Clean up
xmlStream.Close()
jntStream.Close()
End Try
End If
End Sub
