How to check for update in c# ?

-----------SOLVED-----------

This is what I did:

I came to the conclusion that using a txt file will be the best way for me ... since readstream wouldn't read .ini .. lol I dont know why
HAHAHAHHAHA I am a newbie, I just made the 2 text boxes invisible because I am just using them to compare the 2 values...

HAHAHAHAH omg now noobiesh was that???

But it works ! :D


using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.IO;
namespace Authenticate
{
    public partial class Authenticate : Form
    {
        public Authenticate()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            int serverV;
            serverV = Convert.ToInt32(TBserver.Text);
            serverV = int.Parse(TBserver.Text);

            int localV;
            localV = Convert.ToInt32(TBlocal.Text);
            localV = int.Parse(TBlocal.Text);

            if (serverV > localV)
            { //DO THE UPDATE CODE }

            else
            { //DO NOT DO THE UPDATE CODE }
          
        }

        private void Authenticate_Load(object sender, EventArgs e)
        {
         
          
            WebClient Client = new WebClient();
            Client.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed);
            Client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged);
            Client.DownloadFileAsync(new Uri("http://98.118.57.8/anti/version.txt"), "versionS.txt");


        }

        private void ProgressChanged(object sender, DownloadProgressChangedEventArgs e)
        {
            //progressBar1.Value = e.ProgressPercentage;
        }

        private void Completed(object sender, AsyncCompletedEventArgs e) {
       
       
StreamReader SRlocal = new StreamReader("versionL.txt");
TBlocal.Text = SRlocal.ReadToEnd();
SRlocal.Close();


StreamReader SLserver = new StreamReader("versionS.txt");
TBserver.Text = SLserver.ReadToEnd();
SLserver.Close();
       

       
        }//what ever to do after completed
    }
}

Like, This is what I am trying to do...

http://98.118.57.8/anti/version.jpg

As i show in that picture, I don't mind if it is a text file, or a .ini file... but that's kind of how I want to do it...

If the SAME file on the server, has a greater number than the Local one, I want the update to install automatically...
The extract and install parts I will be ok with...

The only thing I don't know how do to, is read the text inside the text file, and compare...

I was thinking about this:

Downloading text file at program's startup,
Now that the file is local, How do I compare the 2 text files? ...

How do I Read the LINE 1 of the file, and transform it in an integer..

raw example...

int updateserver.ini.line1 = i;
int updatelocal.ini.line1 = p;

if(i > p);
{UPDATE}
else
{return}

so pretty much, I just want to read the number off of the first line, and transform it as an integer...
I will not have dashes etc...

It will be like...

1
or
2

to make things easy...

THANKS GUYS :D




-----EDIT-----

i was thinking... will this work?

using System.IO; StreamReader streamreader1 = new StreamReader("updateserver.ini"); textBox1.Text = streamreader1.ReadToEnd(); streamreader1.Close(); StreamReader streamreader1 = new StreamReader("updatelocal.ini"); textBox2.Text = streamreader1.ReadToEnd(); streamreader1.Close(); if(textbox1.Text > textBox2.Text) {} else {}

That might work right?

Or do I have to do..

int textBox1.Text ?
int textBox2.Text ?

.... Thaths the only idea I can come up with

Nice bro... Thanks a lot.. this is something I will definitely try sometime...

But, would you know a way to do it off of a .ini file instead? ... I mean..

in most MMO games, there is a file called version.ini ...

In the version . ini, there is usually just 1 line..

I want to try to do it with out using XML, But I will definitely keep your tutorial for future reference.

Thanks man !!!
