I don’t know what is going on.
And here is my c# code
using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
using System.Net;
using System.IO;

string logpath)
{
long length = 0;
string boundary = "----------------------------" +
DateTime.Now.Ticks.ToString(“x”);
HttpWebRequest httpWebRequest2 =

Here is My ruby on rails code
class FilelinkController < ApplicationController
require “ftools”
scaffold :filelink
def index
redirect_to :action => “list”
end
def list
@filelink = Filelink.find_all
end
def uploads
link = String.new()
@link = Date.today().strftime(“%d_%m_%y”).to_s()
@filelink = Filelink.new()
@filelink[‘patientname’] = @params[‘patientname’]
@filelink[‘filelink’] = “#{RAILS_ROOT}/public/file/”+@link+“.txt”
File.open(@filelink[‘filelink’], “wb”) { |f|
f.write(@params[‘any_file’].read) }
#do |f|
#f.write(@params[‘any_file’].read)
#end
@filelink.save
redirect_to :action => “list”
end
###The Used Part
def upload2
if File.size?(@params[‘any_file’])>0
File.open(“#{RAILS_ROOT}/public/file/try.txt”, “wb”) do |f|
f.write(@params[‘any_file’].read)
end
else
redirect_to :action =>“list”
end
redirect_to :action =>“list”
end
end
And here is the form
Upload file formAdd a patient records
The HeartBeat file :
For more information, i use Aptana as the development platform of ror,
and i use visual studio.net 2005 as the c# development platform.
