Android Question Base64 conversion

[FormCommander]

Hello,
I want to send an image and additional infos to my webserver with a HTTP job. I see that I can do this with PostFile. But here I cannot send the additional infos like with Download2 and the parameters. So I think the best way is to create a xml with the base64 encoded image and send it as file.
But converting this way does not work because of a casting error message:

Dim cImgSend As Byte = FileToBytes(cPhotoDir,cPhotoFile)
        Dim b() As Byte = su.EncodeBase64(cImgSend)

I would try to put the encoded string in a xml field with XMLBuilder, can this make problems ? I think I must convert back to a string.
Or is there a better way to send the data in a http job ?
regards
Rudolf

Dim b() As Byte = su.EncodeBase64(cImgSend)

EncodeBase64 does NOT return a Bytearray. It returns a STRING

Dim base64string As String = su.EncodeBase64(cImgSend) ' Use base64string in your okhttputils call
