Chilkat for the Universal Windows Platform (UWP)

Dim bd As New Chilkat.BinData

' This example will load a PDF and return it as a base64 string.
Dim success As Boolean = bd.LoadFile("qa_data/pdf/helloWorld.pdf")
If (success <> True) Then
    Debug.WriteLine("Failed to load file.")
    Exit Sub
End If


Dim b64Str As String = bd.GetEncoded("base64")
Debug.WriteLine(b64Str)

' Now write the base64 string back to the binary PDF file:
Dim bd2 As New Chilkat.BinData
success = bd2.AppendEncoded(b64Str,"base64")
success = bd2.WriteFile("qa_output/helloWorld.pdf")
