Cheers

By update button are you meaning to check to see whether or not there is a new version available? If so, you will need hosting, 000webHost will work.

From there, I'll inform you on what you need. I was actually looking to make this my next tutorial in C# for my website. I might just write it up today for you.

Ohh Thanks Man Give Me Your Website i Love to Check it out and could you add Me On Skype mrspliiffymodz So you can go bit more in-depth ?

You must login or register to view this content.

I heavily commented the source code. You can basically add a button and add the source code and change a few things. You will need to create an XML file as well as use a web host, you can use free ones.

If you have web hosting, this is extremely easy.

A simple way to do it would be to create a directory in FTP containing a text file, and a string called 'Version' in your program.

On the first line of the text file, include the target version, and on the second line, include the download link.

read the content from the URL and check if the first line of your content matches your 'Version' variable. If it does, don't update. If it doesn't, send the user to the download link on the second line.

Code example:

    

WebClient client = new WebClient();

            Stream stream = client.OpenRead(<URL>;

            StreamReader reader = new StreamReader(stream);

            string content = reader.ReadToEnd();





            string[] vals = content.Split('\n';





            //vals[0] = version

            //vals[1] = download link





            if (vals[0] == BotInfo.Bot_Version)

            {

                System.Windows.Forms.MessageBox.Show("No new updates", "Check for Updates", System.Windows.Forms.MessageBoxButtons.OK, System.Windows.Forms.MessageBoxIcon.Information);

                return;

            }





            if (vals[0] != BotInfo.Bot_Version)

            {

                System.Windows.Forms.MessageBox.Show("New Update found! Version: " + vals[0], "Update Found", System.Windows.Forms.MessageBoxButtons.OK, System.Windows.Forms.MessageBoxIcon.Information);

                System.Diagnostics.Process.Start(vals[1]);

            }

Did mine using an XML file although I noticed a small bug; I've gotta tweak it to where it can accept multiple elements in the XML file so you can use a single update file rather than having to direct towards a specific XML file.

Still, it works.

Its just something simple

You've taken it and made it appear at load, you can do that though it's not needed. I also see you added the ability to download the file, that's something good there; though it wasn't what was asked aha.

Also, you don't need to include else statements and //do nothing or dialog == dialogResult.No {Cancel Dialog} since it does nothing regardless due to the bool values not resulting in true.

Yh I know but I always do Is something that I got used to , and I wasnt talking about putting it on Form_Load I was talking about the SaveFileDialog because it comes handy and the Download Function hehe.
Il be giving credit to you I only minimally Upgraded it

No credit needed. I just put the stuff out there to help others. When I was learning C# I didn't really have much tutorials, snippets, etc to work off of so I had to go about the hard way.
