hello,

Using vb.net I need to read a file (whos path i kno) and convert the file into base 64 encoding within an xml node. Thus far I have attempted the following where cFile is the path of the file


            fs = New FileStream(cFile, FileMode.Open, FileAccess.Read)
            fs.Read(bytes, 0, bytes.Length)
             str64 = Convert.ToBase64String(bytes)

then putting it into xml

If cFile <> Nothing Then
                objField = objDOM.createElement("MSGFILE")
                objField.dataType = "bin.base64"
                objField.nodeTypedValue = str64
                objRow.appendChild(objField)
End If

but receive the folowing error:

Procedure call or argument is not valid.

thanks.

not to worry problem sorted :

solution:

Dim s As String
            Dim f As New System.IO.FileStream(cFile, IO.FileMode.Open, IO.FileAccess.Read)
            Dim b(f.Length) As Byte
            f.Read(b, 0, f.Length)
            s = Convert.ToBase64String(b)
