Right, you can not pass a stream to the GetBytes method. Pass a String or an
array of Chars.

Thanks Armin, but I'm a bit lost here. How would I change my code to
pass a string or array of chars?

Thanks

When you create the Streamreader, you can pass an Encoding object that
specifies the encoding of the chars in the stream. After reading a string
from the Stream, you can pass it to the GetBytes method of an Encoding
object to get the encoded byte array.

I'm creating the streamreader ok , but can't work out how to do the
rest. This bit encodes the stream as iso-8859-1, but how do I convert
this to a string?

system.Text.Encoding.GetEncoding("ISO-8859-1")
Dim readStream As New StreamReader(receiveStream, encode)

What do you want to convert to a string? If the text in the stream is
encoded in "ISO-8859-1", you can now use the stream to read from
(readStream.readline or readStream.readtoend).

Later you can convert the string to a byte array by passing it to the
GetBytes method of an Encoding object.

Now I'm really confused....I thought you were telling me I need to
convert the streamreader to a string before it can be passed to the
getbytes method.

Is it possible you could show me how to modify the code? I'm quite

I don't know what's your intention. You wanted to get the bytes from a
stream in a certain encoding, right?

Yes but getting the following error:

Now we are as far as yesterday.

What do you want to do?? What is your intention??

You can NOT pass a streamreader to the GetBytes function. You can pass a
string to the GetBytes function. I don't know which string you want to pass.
I assume, you first want to read the string from the Streamreader and then
pass it to GetBytes. Is this right or wrong? If it is right, use the
Streamreaders ReadLine or Readtoend method. Then you have a string and you
can pass it to GetBytes. Where is the problem with doing it? Or is it not
what you want to do? I don't know.

You don't know how to call a method?

- WebRequest.Create
- HttpWReq.GetResponse
- HttpWResp.GetResponseStream
- Encoding.GetEncoding

These are all method calls in your code, so I think you do know how to call
a method. Sorry, I don't understand.

dim s as string

s = readStream.Readline

d = System.Text.Encoding.ASCII.GetBytes(s)

This reads a line, then gets the bytes encoded using ASCII encoding.
