Program Launcher Help

[dog199200]

Hello;

I have just started programming in C# and I have a project I have been working on. first off i'm a video game programmer so I tend to not do visual things like C# so i'm a bit clueless and right now i'm trying to build a game launcher using C#. Now i think I got all the coding in place, but the problem is for some reason it wont check online files like it is suppose to so it wont check the version of the program i'm running, and then it wont download patch files either. Well i think the code might explain it better after looking at it.

using System;
using System.ComponentModel;
using System.Windows.Forms;
using System.Diagnostics;
using System.IO;
using ICSharpCode.SharpZipLib.Zip;
using System.Net;

namespace Divine_Shadows
{
    public partial class DSL : Form
    {
        public DSL()
        {
            InitializeComponent();
        }
        public WebClient update = new WebClient();
        public FastZip zip = new FastZip();
        private void DSL_Load(object sender, EventArgs e)
        {
            decimal Version = 0.0m;
            {
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.divineshadowsonline.com/game/version.txt");
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                StreamReader sr = new StreamReader(response.GetResponseStream(), System.Text.Encoding.GetEncoding(1252));
                string Online = "0.0";
                Online = sr.ReadToEnd();

                if (Version >= Convert.ToDecimal(Online))
                {
                    File_Progress_Title.Text = "100%";
                    Total_Progress_Title.Text = "100%";
                }
                else
                {
                    VersionOld.Visible = true;
                }
            }
            update.DownloadProgressChanged += new DownloadProgressChangedEventHandler(DownloadProgressCallback);
            update.DownloadFileCompleted += new AsyncCompletedEventHandler(DownloadCompleted);
            Update_Status.Text = "Updating...";
            while (update.IsBusy)
            {
                Application.DoEvents();
            }
            update.DownloadFileAsync(new Uri("http://www.divineshadowsonline.com/game/updates/patch.zip"), @"C:\patch.zip");

        }
        public void DownloadProgressCallback(object sender, DownloadProgressChangedEventArgs e)
        {
            File_Progress_Display.Value = e.ProgressPercentage;
            File_Progress_Title.Text = Convert.ToString(e.ProgressPercentage) + "%";
        }

        public void DownloadCompleted(Object sender, AsyncCompletedEventArgs e)
        {
            zip.ExtractZip(@"C:\patch.zip", Application.StartupPath.ToString(), @"C:\Program Files\Divine Shadows\");
        }
        private void Close_Click(object sender, EventArgs e)
        {
            Close();
        }

        private void Register_Click(object sender, EventArgs e)
        {
            Process.Start("http://www.divineshadowsonline.com/register.php");
        }

        private void Play_Click(object sender, EventArgs e)
        {
            Process.Start("Game.exe");
        }

        private void Minimize_Click(object sender, EventArgs e)
        {
            this.WindowState = FormWindowState.Minimized;
        }
    }
}

Any and all help to let me know what i'm doing wrong will be greatly appreciated. And if you need to see an image of the launcher program let me know so I can et a screenshot so you can get an better idea of what the code is suppose to do.

[vcdebugger]

can you clearly break up your problem in to smaller ones ?
Also where are you creating the worker thread Update in your code ?

[dog199200]

well to break it down the best I can. The progress bar Wont Work, the program isn't sending out to check the program version like it should, and the patching system ain't working. So basically anything that has to do with reaching out for internet files wont work.

Also i'm not sure what you mean by update thread. The main patching system is done with ICSharpCode SharpZip which is suppose to look for the zip file in my server, downloads it, and then extracts it, overriding the old files, but it ain't working at all. Then the Progress Bar is suppose to work alo0ng side the patching. Then the version this is what is the trigger. What its suppose to do is look for a file on my server (http://www.divineshadowsonline.com/game/version.txt) and then checks it with the file versions within the program and if the files are older, it then activates the patching tool to get the files. but none of it is working at all.

I've made a few adjustments to the code above so here is the updated code. Its still don't work, but its been formatted better this time.

where are the following things declared in your code ?
File_Progress_Title.Text = "100%";
Total_Progress_Title.Text = "100%";
VersionOld.Visible = false;
VersionNew.Visible = true;

File_Progress_Display.Value = e.ProgressPercentage;

that all are names assigned to labels, which are part of the design code. But I found out my problem was that the DSL_Load didn't get called in the design files, so I got that working, but here is the new code I have working:

using System;
using System.ComponentModel;
using System.Windows.Forms;
using System.Diagnostics;
using System.IO;
using ICSharpCode.SharpZipLib.Zip;
using System.Net;
using System.Text;

            }
            else
            {
                this.VersionNew.Visible = false;
                this.VersionOld.Visible = true;

        }

        {

        }
    }
}

The problem is it finds the fine and downloads it to the right place, but it doesn't extract it. And since I got the main idea from another code, i'm not sure if i'm going things right, but here are the lines related to finding the file, downloading it and are suppose to extract the file.

update.DownloadFileAsync(new Uri("http://www.divineshadowsonline.com/game/updates/patch.zip"), @"C:\Program Files\Divine Shadows\patch.zip");

and

zip.ExtractZip(@"C:\Program Files\Divine Shadows\patch.zip", Application.StartupPath.ToString(), @"C:\Program Files\Divine Shadows");

but if the last one keep causing the error after the file fully downloads, so i'm sure its the problem.

[vcdebugger]

so you mean to say private void DSL_Load(object sender, EventArgs e) was not getting called?
what did you change in your designer file to get it work ?

[dog199200]

I just needed to add this:

System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(DSL));

[vcdebugger]

cheers!

[dog199200]

yea but i still have a problem or two here and there, but at least its downloading the patch now, i just need to figure out why it wont extract the file to where I want it extracted to.... Then I need to figure out how to get one progress bar to track the files download and then have the other track the files extraction process....

[vcdebugger]

If it is problem with Zipping/Unzipping then you need to check out with the code related to that.
For the progress Bar display you need to attach that control to one of the form and set the visible field to true.

[dog199200]

well I got the bars in place, umm this might help some to give you an idea what i want done with the bars:

http://i25.photobucket.com/albums/c5...aunchPanel.png

The top one will check the downloading progress and the other will tell the unzipping progress. I got the downloading process to work, but the part of the code that does the unzipping progress wont let me setup a progress bar in it without causing an error.

[vcdebugger]

I got the downloading process to work, but the part of the code that does the unzipping progress wont let me setup a progress bar in it without causing an error.

show the source code you have tried and what specific error is it showing ?

[dog199200]

well for the over all source code i'm using ICSharpCode.SharpZipLib.Zip as a reference which is a C# compiling core system. This is what is suppose to extract the files:

public void DownloadCompleted(Object sender, AsyncCompletedEventArgs e)
        {
            zip.ExtractZip("patch.zip", Application.StartupPath.ToString(), @"C:\");
            Update_Status.Text = "Installing Patch...";
        }

to be exact its:

zip.ExtractZip("patch.zip", Application.StartupPath.ToString(), @"C:\");

but I have no idea what to really use. When i found the code it looked like this:

zip.ExtractZip("", Application.StartupPath.ToString(), "");

so I assumed the first set fo "s is the file and the second is either the files location of the extraction location, but neither work, all I know is if you don't end the last one with a trailing slash it screws up the Application.Run(new DSL()); function under the Program file.

[vcdebugger]

Is ICSharpCode.SharpZipLib.Zip is a library or dll ?
Do you have the source code for it ?
what is the return type of Zip.ExtractZip(....) function ?
Why dont you check the return type of it and see was the function successfull or not ?

If you have the source code then try to put break point and trace it through as to why this Zip function is failing
