[C#] URI behaving badly

[ryuchao009]

Hi, I've been trying to work on a patcher for flyff in C# for the past few days due to boredom

I've been able to use NavigationService() linked to my frame in XAML to do webpage navigation, but when I try to use variables to set up the navigation, I get an exception.

This is the code for how I have the NavigationService() set up

String NewsPageNavigation = "http://" + Configuration.IPaddress + "/" + Configuration.Newspage;
NewsPage.NavigationService.Navigate(new Uri(NewsPageNavigation)); 

I had also tried using new Uri() and inputting the contents for the string there, but I kept getting the same exception.

This is the code for the classes (it seemed the easiest way to make my configuration variables universal throughout the program)

 public static string configfile = "config.txt";
 public static string UpdateCheckerFile = "list.txt.gz";
 public static float UpdaterVersion;
 public static string NeuzParam;
 public static string IPaddress;
 public static string Newspage;
 public static string Registerpage;
 public static string PatchDir;
 public static string ResourcesFolder; 

This is how I was reading in the contents of my configuration file

TextReader txtConfig = new StreamReader(Configuration.configfile);
{
     Configuration.UpdaterVersion = txtConfig.Read();
     txtConfig.ReadLine(); //I added this because I was getting an exception with the Navigation trying to use NeuzParam in the URI string
     Configuration.NeuzParam = txtConfig.ReadLine();
     Configuration.IPaddress = txtConfig.ReadLine();
     Configuration.Newspage = txtConfig.ReadLine();
     Configuration.Registerpage = txtConfig.ReadLine();
     Configuration.PatchDir = txtConfig.ReadLine();
     Configuration.ResourcesFolder = txtConfig.ReadLine();
}
txtConfig.Close(); 

Lastly, Here's the contents of my config.txt

1.0 
sunkist
localhost  
newspage.php
register.php 
Neurospace/RESCLIENT 
Resources

I'm using VS 2010 Beta 2 so I don't know if that's the problem or not. When I used Uri("http://localhost/newspage.php") it works fine, just not when I try to do it with my configuration variables and the + operator. I set up a try...catch to make sure it's reading in the correct lines for the Uri, and the ouput it's giving says that it is. I can post some screenshots if it'll help.

If you've got any suggestions, please let me know. I've spent a few hours googling around with no luck.

I don't really know C# at all, but I did some searching around.

String NewsPageNavigation = "http://" + Configuration.IPaddress + "/" + Configuration.Newspage; 
Uri myUri = new Uri(NewsPageNavigation);
WebRequest wr = WebRequest.Create(myUri); 

Just taking a shot in the dark here, but your syntax doesn't match too well with other references I found. Maybe you can pick apart something and make it work..

Thanks for trying, but still no good. I'm getting the same error as the other way I was doing it

Error:

System.UriFormatException: Invalid URI: The hostname could not be parsed.
 at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)
 at System.Uri..ctor(String uriString)
 at flyff_patcher.MainWindow..ctor() in X:\Useers\Myusername\Documents\Visual Studio 2010\Projects\flyff_patcher\flyff_patcher\MainWindow.xaml.cs:line 38

I forgot to mention why I was using NavigationService() lol. I coded the interface in XAML, and the guide I was reading about XAML frames said to use NavigationService() to load a webiste inside of the frame.

Have you tried these?

(example of use)

void goObjectButton_Click(object sender, RoutedEventArgs e)
{
this.NavigationService.Navigate(new ContentPage());
}

To replace "ContentPage()"..?

The following code works ok:

            string address = "localhost";
            string file = "news.php";

            string fullAddress = "http://" + address + "/" + file;

            Uri testURI = new Uri(fullAddress);

            Console.WriteLine("Successfully created Uri object for: " + testURI.AbsoluteUri);
            Console.ReadKey();

are you sure that Configuration.IPaddress is populated with value at the moment when you use it to create address?
Add it to watchlist and set a breakpoint at that line or add something like Console.WriteLine(Configuration.IPaddress) below or above that line and look what it will produce.

Why don't you do the following:
On the website, make a file called latestversion.v.

In that, type in the latest version (Ex, 5).

Now, use WebClient to connect to that page and download the content
(which would be the version you typed in; (Ex. 5))

Then, get the version of the current client, and if its older, download the new file, by using WebClient to download the content of the EXE and renaming it to an exe.

Example:
The latest client is located at web.tld/new.exe

Use WebClient to download new.exe, then rename the resulting file to client.exe (or whatever)

You could do something with updating certain parts of the file to make the update faster, but that's advanced stuff.
