Help!
I'm posting a PDF Doc to a remote server using WebClient UploadData and the
following code. The DOC posts fine and the server returns a positive
response. If I access the remote file in Firefox the Adobe PDF Reader in
Firefox kicks off and I can view the file just fine. HOWEVER, if I try to
access the file using Internet Explorer Adobe never kicks off and I receive a
screenfull of text (which looks like the raw text data of the PDF). This
same behavior is seen by anyone accessing the document (so its not a browser
issue on my side). It must be something that I'm not posting correctly -
like the Content-Transfer-Encoding. But for the life of me I can't figure it
out. Any help would be greatly appreciated!
Thanks a bunch!
This is the code:
--------
Sub SendFile
Dim myWebClient As New System.Net.WebC lient
Dim body As String
Const boundary as String = "xz9xBzBYzZ Y"
FileName = "ABC.PDF"
' Read file contents into Byte Array
Dim st As New FileStream(File Name, FileMode.Open)
Dim FileBytes() As Byte
ReDim FileBytes(st.Le ngth)
st.Read(FileByt es, 0, st.Length)
st.Close()
myWebClient.Hea ders.Add("Accep t", "image/gif, image/x-xbitmap, image/jpeg,
image/pjpeg, */*")
myWebClient.Hea ders.Add("Refer er", "")
myWebClient.Hea ders.Add("Accep t-Language", "en-us")
myWebClient.Hea ders.Add("Conte nt-Transfer-Encoding",
"applicatio n/octet-stream")
myWebClient.Hea ders.Add("Conte nt-Type", "multipart/form-data; boundary=" &
boundary)
myWebClient.Hea ders.Add("User-Agent", "Mozilla/4.0 (compatible; MSIE
6.0;Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)")
myWebClient.Hea ders.Add("Cache-Control", "no-cache")
myWebClient.Hea ders.Add("Cooki e", "KEY=" & SomeCookie)
' Create Body
body = ""
body = body & "--" & boundary & vbCrLf
body = body & "Content-Transfer-Encoding: binary" & vbCrLf
body = body & "Content-Disposition: form-data; name=""file_1"" ; filename="""
& FileName & """" & vbCrLf
body = body & "Content-type: application/pdf" & vbCrLf & vbCrLf
dim body2 as String
body2 = "--" & boundary & "--" & vbCrLf
Dim byteBodyArray As Byte()
byteBodyArray = Encoding.defaul t.GetBytes(body )
Dim byteBodyArray2 As Byte()
byteBodyArray2 = Encoding.defaul t.GetBytes(body 2)
Dim ByteArrayToSend () As Byte
ReDim ByteArrayToSend (byteBodyArray. Length + FileBytes.Lengt h +
byteBodyArray2. Length)
byteBodyArray.C opyTo(ByteArray ToSend, 0)
FileBytes.CopyT o(ByteArrayToSe nd, byteBodyArray.L ength - 1)
byteBodyArray2. CopyTo(ByteArra yToSend, byteBodyArray.L ength +
FileBytes.lengt h - 2)
Dim bResponseArray As Byte() = myWebClient.Upl oadData(PostURL , "POST",
ByteArrayToSend )
End Sub

Two notes:
1. There's no HTTP header Content-Transfer-Encoding. What you want is
"Content-Type".
2. WebClient.Uploa dFile() does exactly what you're trying to achieve
(although there's a bug in pre .NET 2.0 implementations ). Did you try
it?

Hi,
We are using UploadData method of WebClient class in C# to establish
connection(s) between two machines(typical client/server). Connection
is established if the machines are on same domain. If machines are on
different domains client state is SYN_SENT (and not ESTABLISHED as
expected).
This problem does not arise if we use sockets.
Is this a problem with WebClient class or is it some networking
issue(firewall etc)?
Thanks,

Hello,
I have a executeble that sends a request to a webserver:
Return Encoding.UTF8.GetString(myWebClient.UploadData(uri, "POST",
Encoding.UTF8.GetBytes(postString)))
We are a having a problem that if we run it multiple times in a short time
span something fails. ANd I was wondering if the webclient could be the cause
of problems.

I'm having a problem with the WebClient object. When I post data to certain
sites, it will receive a command from the webserver (object moved) and
continue to the next link by downloading that. The problem is, certain
cookies need to be set, and the only way of doing that is not letting the
WebClient automatically go on to the next GET in the background--I need to
do it manually.

I read many examples with NetworkCredential and WebClient, but no one
with a real http address.
They all work in theory, but I wasn't able to use them in the real
world.
The following code should access an ebay page. There is no
redirection involved in TestPage. If you have an ebay account you can
try it in 1 minute.
What's wrong with my code?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
