I want to design a webservice that can enable me send data to and from client machine. I sed code below but it was giving me errors. I changed FileStream to StreamWriter and StreamReader, it complained about using C drive since I dont have access to it Dim fs1 As New FileStream("C:\" & fo.Name, FileMode.Create).

When I changed Dim fs1 As New FileStream("C:\" & fo.Name, FileMode.Create) to dim fs1 as new StreamWriter(path & fiename) and it worked but when I open the file it gives me strange xters.

Please help me look at the code below and suggest possible solutions if not a new idea.

Again it there anyway I could know scanners connected to my computer?

Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.IO
<WebService(Namespace:="http://mysite.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> <System.Serializable()> _
Public Class Service
Inherits System.Web.Services.WebService

<WebMethod()> _
Public Function FilePosted(ByVal Filename As String) As String


Try
Dim path As String = Context.Server.MapPath("~/"
Dim fo As New FileInfo(Filename)
Dim fs As New FileStream(Filename, FileMode.Open)

Dim fs1 As New FileStream("C:\" & fo.Name, FileMode.Create)
Dim nBytes As Integer = fs.Length
Dim ByteArray(nBytes) As Byte


Do While Not fs.Read(ByteArray, 0, nBytes) = 0
fs1.Write(ByteArray, 0, nBytes)
Loop

fs1.Dispose()
fs.Dispose()

Return "Success"

Catch ex As Exception
Return "Failed"

End Try


End Function



End Class

You file contains control xters (naturally), so you need to "protect" the data being transferred. Try encoding the file with Base64 encoding, that will allow you to transfer it as a string over regular HTTP. When it gets to the other end, it can then be decoded. I have written a C#/.NET app that retrieves/sends peoples pictures (JPEG files) over a webservice.

Please can you help me with some part of the code of all such that I will modify it to suit my need. Thanks

Did you ever figure out what the problem was??

I tried my best but I still get the same error response.
Can anybody help me out?

I am sort of busy at this time myself as I have a deadline to meet. Check the following articles out to help you

Thanks so much I will go through it. I will let you know whether if it solves my problem.

Must I use credentials before calling my web services?

Nope

Do u know the funny aspect of it, if I tested the webservices on its own its works but if I refrence it it iwll not.
Still batlling about it, because I need what I will use to transport file from on system to another without sharing the folder.
I will aprreciate any of ur contributions.
I ve gone to the site but dont get much.

Reponse, you can't access the client machine to force a file upload due to security restrictions.
The client needs to explicitely select and upload the file.

So I can't write a web service that can easily allow my use client machine, pass the filename and it wil go straight to the server?
I think that should be possible that is what compound to my problem.

I need to reference the class from another client to enable me transfer files.

I still believe that this is way out.

Response :

you cant,

You could try an ActiveX installed on the client, or even better would be an exe/service installed on the client.

But without somethign installed on the client you can't force the upload of a client file.
