How to send a DIME attachment with SOAP

[Ipsita]

Hi!

I am trying SOAP with DIME attachments in web services. The web
service sends the file as attachment say "test.doc", and the client
has to read that and populate it in a textbox control. I had asked
this question earlier, and got the reply that the data is tranferred
in binary format on the wire. I read the stream, and convert it to
string, but I get some junk characters in my textbox. I am writing my
code below, so that you can see what I am doing wrong, and correct me.
This is what I do:

On Server:
----------
[WebMethod]
public void GetDoc()
{
SoapContext respContext = ResponseSoapCon text.Current;
DimeAttachment dimeAttach = new DimeAttachment( "applicatio n/msword",
TypeFormat.Medi aType,
@"D:\Images\Tes t.doc");
respContext.Att achments.Add(di meAttach);
}

On Client:
----------
private void btnGetDoc_Click (object sender, System.EventArg s e)
{
MyDimeService svc = new MyDimeService() ;
svc.GetDoc();
if (svc.ResponseSo apContext.Attac hments.Count == 1)
{
MessageBox.Show ("Got it!\n");
// Get the stream and do something with it
Stream s = svc.ResponseSoa pContext.Attach ments[0].Stream;
byte [] binaryData = new byte[s.Length];
long bytesRead = s.Read(binaryDa ta, 0, binaryData.Leng th);
s.Close();
string base64String;
try
{
base64String = System.Convert. ToBase64String( binaryData, 0,

binaryData.Leng th);
}
catch (System.Argumen tNullException)
{
System.Console. WriteLine("Bina ry data array is null.");
return;
}
txtGetDoc.Text = base64String;
} //end of if
} //end of private..

Waiting for an answer...

Thanks

what are you expecting to appear in the textbox?

from your code I'd expect the textbox to contain the base64 string which is
the encoding of the binary data, and from your description it sounds like
you are getting that.

a textbox only supports displaying plain text, if test.doc cannot be viewed
correctly with notepad.exe, a textbox cannot either.
