[Code]C# - App.Config reader

I just want to share my code for reading app.config file. I wrote it earlier for my current project - JWMD Stuick.
I just want it simple and clean and my/an alternative of (I never used it though) OpenNETCF.Configuration.
here's the code
PHP:
using System;
using System.Collections.Generic;
using System.Xml;
using System.Xml.XPath;
using System.IO;
namespace ApplicationConfiguration
{
public class Configuration
{
XmlDocument xmldoc;
string _applicationname = string.Empty;
string _appconfigfile = string.Empty;
Dictionary<string, string> _appSettings = new Dictionary<string, string>();
public Dictionary<string, string> AppSettings
{
get { return _appSettings; }
}
public Configuration()
{
string startup = System.Reflection.Assembly.GetCallingAssembly().GetName().CodeBase;
FileInfo fi = new FileInfo(startup);
this._applicationname = System.IO.Path.GetFileNameWithoutExtension(startup);
this._appconfigfile = System.IO.Path.Combine(fi.DirectoryName.ToString(), _applicationname + ".exe.config");
Read();
}
void Read()
{
xmldoc = new XmlDocument();
xmldoc.Load(this._appconfigfile);
XmlNodeList nodeCol = xmldoc.SelectNodes("//add");
if (nodeCol != null)
{
foreach (XmlNode thisNode in nodeCol)
{
string key = thisNode.Attributes["key"].Value.ToString();
string value = thisNode.Attributes["value"].Value.ToString();
this._appSettings.Add(key, value);
System.Diagnostics.Debug.WriteLine(key + ", " + value);
}
}
}
}
}
to make this work, make sure app config file is named the way Windows Forms rename the app.config.
e.g. your application name is "mysuperapplication" then the app config file must be "mysuperapplication.exe.config"
below is a application test.

TypeLoadException

Hey all I'm getting a TypeLoaderException in the following:
Code:
private object RetrieveObject(string dllLocation, ClassDetails classIdentifier)
{
System.Reflection.Assembly assem = Assembly.LoadFrom(dllLocation);
try
{
// ClassIdentifier.Details() = "Service1.Service1" which is correct
Type t = assem.GetType(classIdentifier.Details(),true); // FAIL HERE
return Activator.CreateInstance(t);
}
catch(Exception ex)
{
RequestListener.AppendLog("Exception occured at SD RetrieveObject: " + ex.ToString());
}
return null;
}
The class I'm trying to resurrect is the following
Code:
namespace Service1
{
public class Service1 : System.Web.Services.WebService
{
public Service1()
{
}
[WebMethod(MessageName = "SayHello")]
public string HelloWorld()
{
return "Hello World";
}
}
}
Any ideas why this is failing?

[Q] [.net cf]Loopback

Hey guys
I'm developing a little webserver for WM with the .net cf. it's easy and works fine as long as I don't try to access it from the same device it's running on. Nothing works: localhost,127.0.0.1 or even if I'm connected to a wifi network and I use this IP. Has anyone the solution for this issue?
ta you
a yeah I use the TcpListener-Class and I implemted some simple HTTP.

Code
Hey guys
Noone has an idea??
Here is the code which I use to setup the HttpListener and answer connections.
Code:
using System;
using System.Linq;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.Net.Sockets;
using StedySoft.SenseSDK;
using System.Threading;
using System.IO;
namespace WebServer
{
public partial class ServerForm : Form
{
IPEndPoint local;
TcpListener listener;
private volatile bool stop;
private volatile bool handled;
SensePanelItem state;
SensePanelTextboxItem response;
Thread serverThread;
public ServerForm(IPEndPoint local)
{
InitializeComponent();
this.local = local;
SetupList();
}
private void SetupList()
{
SensePanelDividerItem infos = new SensePanelDividerItem("infd", "Infos");
mainList.AddItem(infos);
mainList.AddItem(new SensePanelItem("Local-Endpoint") { PrimaryText = "Local-Endpoint", SecondaryText = local.ToString() });
mainList.AddItem(state = new SensePanelItem("Status") { PrimaryText = "Status", SecondaryText = "Wird gestartet..." });
mainList.AddItem(new SensePanelDividerItem("Response", "Response"));
mainList.AddItem(response = new SensePanelTextboxItem("body") { LabelText = "HTML-Body, welcher auf Requests gesendet wird.", Text = "<span style =\"color:red;font-size:30pt\">It works!!</span>" });
mainList.AddItem(new SensePanelDividerItem("Requests", "Requests"));
}
private void StartServer()
{
if (listener != null)
{
StopServer(true);
}
listener = new TcpListener(local.Port);
listener.Start();
serverThread = new Thread(listen);
serverThread.IsBackground = true;
stop = false;
serverThread.Start();
state.SecondaryText = "Gestartet...";
}
private void listen()
{
while (!stop)
{
while (listener.Pending())
{
handled = false;
Thread handlingThread = new Thread(handler);
handlingThread.Start();
while (!handled)
Thread.Sleep(50);
}
Thread.Sleep(200);
}
}
private void handler()
{
// Get the current connection
TcpClient client = (TcpClient)this.Invoke(new Func<TcpClient>(listener.AcceptTcpClient));
IPEndPoint remote = (IPEndPoint)client.Client.RemoteEndPoint;
handled = true;
NetworkStream stream = client.GetStream();
StreamReader reader = new StreamReader(stream);
ReadHttpRequest(reader);
StreamWriter writer = new StreamWriter(stream);
StringBuilder response = new StringBuilder(); ;
StartHTML(response);
response.AppendLine((string)this.Invoke(new Func<IPEndPoint, string>(GetResponse), remote));
EndHTML(response);
WriteHTTPResponse(writer, response.Length);
writer.WriteLine(response.ToString());
writer.Flush();
stream.Close();
client.Close();
}
private void WriteHTTPResponse(StreamWriter writer, int length)
{
writer.WriteLine("HTTP/1.1 200 OK");
writer.WriteLine("Date: " + DateTime.Now.ToString());
writer.WriteLine("Content-Length: "+ length.ToString());
writer.WriteLine("Connection: close");
writer.WriteLine("Content-Type: text/html; charset=utf-8");
writer.WriteLine();
}
private void ReadHttpRequest(StreamReader reader)
{
string buffer = null;
while (buffer != "")
buffer = reader.ReadLine();
}
int counter = 0;
private string GetResponse(IPEndPoint remote)
{
counter++;
mainList.AddItem(new SensePanelItem(counter.ToString()) { PrimaryText = remote.ToString(), SecondaryText = "Response:" + counter.ToString() });
return response.Text;
}
private void EndHTML(StringBuilder writer)
{
writer.AppendLine("</body>");
writer.AppendLine("</html>");
}
private void StartHTML(StringBuilder writer)
{
writer.AppendLine("<?xml version=\"1.0\"?>");
writer.AppendLine("<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">");
writer.AppendLine("<html xmlns=\"http://www.w3.org/1999/xhtml\" xml:lang=\"de\" lang=\"de\">");
writer.AppendLine("<head>");
writer.AppendLine("<title>SmartWebServer</title>");
writer.AppendLine("<meta name=\"author\" content=\"Alexander Kayed\">");
writer.AppendLine("</head>");
writer.AppendLine("<body>");
}
private void StopServer(bool restart)
{
stop = true;
serverThread.Join();
if (restart)
StartServer();
}
private void ServerForm_Load(object sender, EventArgs e)
{
StartServer();
}
private void ServerForm_Closed(object sender, EventArgs e)
{
StopServer(false);
}
private void menuItem1_Click(object sender, EventArgs e)
{
this.Close();
}
}
}
The user can choose the IPEndPoint(constructor), which the server will be bound to, in a prevouis form:
Code:
foreach (IPAddress ip in Dns.GetHostEntry(Dns.GetHostName()).AddressList)
{
item = new SensePanelRadioItem(ip.ToString());
item.PrimaryText = ip.ToString();
item.SecondaryText = ip.AddressFamily.ToString();
item.Tag = ChoosedIp = ip;
item.OnStatusChanged += new SensePanelRadioItem.StatusEventHandler(item_OnStatusChanged);
IPList.AddItem(item);
}
So the user can choose between IPs I got from the DNS (e.g. 127.0.0.1, 192.168.0.1) and type a free (valid) port number (eg. 80, 8080, 8888)
Thanks for Your help!!

Still no answer...
I will post my experiences with this issue as long as I solved it - like small blog. Maybe some of you have the same problem...
I found another strange thing:
I'm able to connect to my Server from a TcpClient from another self-written App (own exectuable, different AppDomain):
Code:
void test()
{
Action<string> setText = new Action<string>(setTestText);
try
{
this.Invoke(setText, "Connect...");
TcpClient client = new TcpClient();
client.Connect(local);
this.Invoke(setText, "Connected...");
NetworkStream stream = client.GetStream();
StreamWriter writer = new StreamWriter(stream);
StreamReader reader = new StreamReader(stream);
writer.WriteLine();
writer.Flush();
this.Invoke(setText, "Read answer");
string buffer = reader.ReadToEnd();
this.Invoke(setText, "Test succeeded");
testing = false;
}
catch
{
this.Invoke(setText, "Test failed");
}
}
And I got a the right answer as well. It's strange, really strange that the browsers (IE,Opera etc.) can't loopback to it?

[Q] Developing app that requires root - freezes after asking for su

I am new to android development and am having an issue. I am working on an app that requires root and when I request it using this code:
Code:
Runtime.getRuntime().exec(new String[] {"su"});
I get the request, Allow it then the app locks up and doesn't go to the next item. I am trying to figure out the debugging environment in eclipse, but have not figured out a way to debug this. Is there something I need to do after acquiring root? The next line of code is a simple Toast, so I know it is locking up at the su command. Is there any documentation on writing root apps anybody can point me to? Or is there a simple answer? Thanks in advance.
EDIT: Just in case the whole code will help, here it is:
Code:
public class toggle extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.main);
String[] results = executeShellCommand(new String[] {"su"});
Toast toast = Toast.makeText(this, results[0], Toast.LENGTH_SHORT);
toast.show();
finish();
}
public String[] executeShellCommand(String[] args) {
Process mLogcatProc = null;
BufferedReader reader = null;
BufferedReader errorReader = null;
String logResult = null;
String errorLogResult = null;
String separator = System.getProperty("line.separator");
try
{
mLogcatProc = Runtime.getRuntime().exec(args);
reader = new BufferedReader(new InputStreamReader(mLogcatProc.getInputStream()));
errorReader = new BufferedReader(new InputStreamReader(mLogcatProc.getErrorStream()));
String line;
final StringBuilder log = new StringBuilder();
while ((line = reader.readLine()) != null)
{
log.append(line);
log.append(separator);
}
logResult = log.toString();
String errorLine;
final StringBuilder errorLog = new StringBuilder();
while ((errorLine = errorReader.readLine()) != null)
{
errorLog.append(errorLine);
errorLog.append(separator);
}
errorLogResult = errorLog.toString();
if((logResult.length() == 0) || (errorLogResult.length() > 0))
{
if(errorLogResult.length() > 0)
{
return errorLogResult.split(separator);
}
else
{
return (new String[] {"null_result"});
}
}
else
{
return logResult.split(separator);
}
}
catch (Exception e)
{
return (new String[] {e.toString()});
}
finally
{
if (reader != null)
try
{
reader.close();
}
catch (IOException e)
{
}
}
}
}

I do this a bunch in my RogueTools app.

Why don't you try it with the state manager in the expression blend ?
