open file from client, get the byte of array then save to server

Dear friend,

As you know that ASP .NET has client side and server side...
it means that we can get and open a file from client (C:\jaguar.jpg) then get the byte of array, then we save it to the server (Server.MapPath(Request.ApplicationPath) & "\Images\HORE.jpg")...
i tried the following code, but it does not work properly when we open the file from client...
Pls help...
Thank you,
hendy

=======source code ===============

                Dim s As Stream = File.OpenRead("C:\jaguar.jpg")
                Dim buffer(s.Length) As Byte
                s.Read(buffer, 0, CType(s.Length, Integer))
                Dim len As Integer = CType(s.Length, Integer)
                s.Close()
                Dim fs As FileStream = New FileStream(Server.MapPath(Request.ApplicationPath) & "\Images\HORE.jpg", FileMode.Create)
                fs.Write(buffer, 0, len)
                fs.Close()

I don't see any client side code in your code. That is server side code - the line that tries to open the jpg file is actually trying to find the file on the server.

For client-side code, you need to write it is javascript or some other client side code. However, keep in mind that it is usually a security violation to access the client's file system from the browser. Why don't you just have the client upload the file to the server, then run your code server-side?

Let me know if you need more help...
