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:

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)
{

}

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;

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("</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.
Take a peek here:

Let me know if you need a hand.

Need help for a simple text app

I was wondering, if someone can guide to create a simple app which simplly displays some text on the middle of the screen and 2 buttons (Left and right arrow) to switch to the next or previous text.
I think someone just helped another user who was looking for help for something similar like me but I cannot find it.
Thanks

You can try out this sample code, starting from an empty silverlight project:
In the MainPage.xaml, add the following snippet inside the Grid element named "ContentPanel".
<TextBlock Name="tblkDisplay" Width="360" Height="100" VerticalAlignment="Top" Margin="0,200,0,0" TextAlignment="Center"></TextBlock>
<Button Name="btnBack" Width="160" Height="80" VerticalAlignment="Top" Margin="-200,308,0,0" Click="btnBack_Click">Back</Button>
<Button Name="btnForward" Width="160" Height="80" VerticalAlignment="Top" Margin="200,308,0,0" Click="btnForward_Click">Forward</Button>
This markup adds a TextBlock, and Forward and Back buttons to the page.
In the in the code-behind (MainPage.xaml.cs), use the following code:
Code:
private int _displayIndex; //position in list of text items to display
private List<string> _textItems; //List of text items to display
// Constructor
public MainPage()
{
InitializeComponent();
}
//Code that get called when the page is navigated to
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
base.OnNavigatedTo(e);
_textItems = new List<string>();
//Add ten items to text list to display
for (int i = 0; i < 10; i++)
{
_textItems.Add("Item" + i.ToString());
}
//For the default, set to first position and display it
_displayIndex = 0;
tblkDisplay.Text = _textItems[_displayIndex];
}
//If not at the first position of the list decrement by one, otherwise move to end of the list
private void Back()
{
if (_displayIndex > 0)
{
_displayIndex--;
}
else
{
_displayIndex = _textItems.Count - 1;
}
}
//If not at the last position of the list increment by one, otherwise move to start of the list
private void Forward()
{
if (_displayIndex < _textItems.Count - 1)
{
_displayIndex++;
}
else
{
_displayIndex = 0;
}
}
private void ShowText()
{
if ((_textItems.Count > 0) //Make sure there are items in the collection to display
&& (_displayIndex < _textItems.Count) // Make sure the index is not higher than how many items in the collection
&& (_displayIndex >= 0)) //Make sure the index is zero or greater
{
tblkDisplay.Text = _textItems[_displayIndex];
}
else
{
tblkDisplay.Text = "No Items.";
}
}
private void btnBack_Click(object sender, RoutedEventArgs e)
{
Back();
ShowText();
}
private void btnForward_Click(object sender, RoutedEventArgs e)
{
Forward();
ShowText();

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