tranfer file via bluetooth to iphone using 32feet

I am trying to transfer a file to my iphone using 32feet bluetooth, but cannot seem to get past the ObexWebResponse.
I have read many post on this but none of the solutions seem to work for me.
The Error i get is
// Connect failed
// The requested address is not valid in its context "address:Guid"
private BluetoothClient _bluetoothClient;
private BluetoothComponent _bluetoothComponent;
private List<BluetoothDeviceInfo> _inRangeBluetoothDevices;
private BluetoothDeviceInfo _hlkBoardDevice;
private EventHandler<BluetoothWin32AuthenticationEventArgs> _bluetoothAuthenticatorHandler;
private BluetoothWin32Authentication _bluetoothAuthenticator;
public BTooth() {
_bluetoothClient = new BluetoothClient();
_bluetoothComponent = new BluetoothComponent(_bluetoothClient);
_inRangeBluetoothDevices = new List<BluetoothDeviceInfo>();
_bluetoothAuthenticatorHandler = new EventHandler<BluetoothWin32AuthenticationEventArgs>(_bluetoothAutenticator_handlePairingRequest);
_bluetoothAuthenticator = new BluetoothWin32Authentication(_bluetoothAuthenticatorHandler);
_bluetoothComponent.DiscoverDevicesProgress += _bluetoothComponent_DiscoverDevicesProgress;
_bluetoothComponent.DiscoverDevicesComplete += _bluetoothComponent_DiscoverDevicesComplete;
ConnectAsync();
}
public void ConnectAsync() {
_inRangeBluetoothDevices.Clear();
_hlkBoardDevice = null;
_bluetoothComponent.DiscoverDevicesAsync(255, true, true, true, false, null);
}
private void PairWithBoard() {
Console.WriteLine("Pairing...");
bool pairResult = BluetoothSecurity.PairRequest(_hlkBoardDevice.DeviceAddress, null);
if (pairResult) {
Console.WriteLine("Success");
Console.WriteLine($"Authenticated equals {_hlkBoardDevice.Authenticated}");
} else {
Console.WriteLine("Fail"); // Instantly fails
}
}
private void _bluetoothComponent_DiscoverDevicesProgress(object sender, DiscoverDevicesEventArgs e) { _inRangeBluetoothDevices.AddRange(e.Devices); }
private void _bluetoothComponent_DiscoverDevicesComplete(object sender, DiscoverDevicesEventArgs e) {
for (int i = 0; i < _inRangeBluetoothDevices.Count; ++i) {
if (_inRangeBluetoothDevices[i].DeviceName == "Uranus") {
_hlkBoardDevice = _inRangeBluetoothDevices[i];
PairWithBoard();
TransferFile();
return;
}
}
// no devices found
}
private void _bluetoothAutenticator_handlePairingRequest(object sender, BluetoothWin32AuthenticationEventArgs e) {
e.Confirm = true; // Never reach this line
}
// not working
// transfers a file to the phone
public void TransferFile() {
string file = "E:\\test.txt",
filename = System.IO.Path.GetFileName(file);
string deviceAddr = _hlkBoardDevice.DeviceAddress.ToString();
BluetoothAddress addr = BluetoothAddress.Parse(deviceAddr);
_bluetoothClient.Connect(BluetoothAddress.Parse(deviceAddr), BluetoothService.SerialPort);
Uri u = new Uri($"obex://{deviceAddr}/{file}");
ObexWebRequest owr = new ObexWebRequest(u);
owr.ReadFile(file);
// error:
// Connect failed
// The requested address is not valid in its context ...
var response = (ObexWebResponse)owr.GetResponse();
Console.WriteLine("Response Code: {0} (0x{0:X})", response.StatusCode);
response.Close();
}
The pairing and authentication works just fine, and I can get the BluetoothService.Handsfree to make a call for me but the transferring of the file fails. Not knowing what the actual error is, I tried almost every service available with no luck.
Can you help me figure out what is going on? This is my first attempt working with Bluetooth services so I still have a ton to learn.

Is it possible to transfer a file from iPhone to Windows desktop via Bluetooth?
However, in case you need to transfer media files (images, videos, etc) from Android device, you can use ObexListener class provided by 32Feet library for this purpose, and then you can simply call _obexListener.GetContext() method that will block and wait for incoming connections.
Once a new connection is received, you can save the received file to local storage, as shown in the below example:
ObexListener _listener = new ObexListener();
_listener.Start();
// This method will block and wait for incoming connections
ObexListenerContext _context = _listener.GetContext();
// Once new connection is received, you can save the file to local storage
_context.Request.WriteFile(#"c:\sample.jpg");
NOTE: When working with OBEX on Windows, make sure to disable the "Bluetooth OBEX Service" Windows service, in order not to let it handle the incoming OBEX requests instead of the desired application.

I walked away from this for a while. and started Trying to use xamiren but then had to create a virtual Mac so that I could have the apple store to just load software on my phone. From there xamerin 'should' work well but its another field and tons more to firgure out.

Get WebDriver of already opened Chrome Browser

I would like to have a IWebDriver of an already opened browser like Chrome. Because then I need to automate a form authentication and/or a basic authentication.
I thought that this
IWebDriver driver = new RemoteWebDriver(new System.Uri("http://localhost:4445/wd/hub"), new ChromeOptions());
would do the trick but it only opens another chrome window. Instead I would like to "read" an already opened one.
Is it possible with selenium? O r should I use another library?

As per the Selenium Issues page:
https://github.com/seleniumhq/selenium-google-code-issue-archive/issues/18
The issue was closed and marked as not feasible
The process of connecting to an existing browser would be on a per-browser basis.
Doing it in IE might be easy, but doing it in Chrome or Firefox would be problematic.
Eg:
Chrome actually receives the commands from Selenium via network / tcp json requests to a specific port.
When Selenium driver stops running - it loses the port number for the Chrome debugging port.
The port may still be open, but it could be anything between 10000 and 30000 etc
Even if you solve it for Chrome, it would then require another bespoke solution for Firefox.
Unless your authentication has a 'Captcha' or bot check in place, I would suggest just automating the authentication stage.
Generally speaking - it is a good practice for Automated tests to be self-contained and not rely on outside interference or external tests.
A browser should start at the start of the test and be terminated at the end of the test.
Assuming you are using Selenium for testing and not for malicious purposes.
Selenium will not be helpful to you at this stage.
If however, you can live with your answer / solution being on Chrome but not the other browsers.
public static Chrome StartChromeDriver(int port)
{
try
{
string Path = Registry.Installation.GetChromeExecutable();
Process p = new Process();
ProcessStartInfo psi = new ProcessStartInfo(Path);
string args = "--remote-debugging-port="+ port.ToString()+" --user-data-dir=remote-profile";
psi.Arguments = args;
psi.Verb = "runas";
p.StartInfo = psi;
p.Start();
return new Chrome("http://localhost:" + port.ToString());
}
catch (Exception ee)
{
Console.WriteLine(ee.ToString());
return null;
}
}
This will start a chrome process with the debugging port opened to the number you provide.
(You can keep track of this, and reconnect and re-issue commands to the running chrome instance)
public dynamic EnablePage()
{
json = #"{""id"":12345,""method"":""Page.enable""}";
Thread.Sleep(1000);
return this.SendCommand(json);
}
public dynamic EnableRuntime()
{
json = #"{""id"":12345,""method"":""Runtime.enable""}";
Thread.Sleep(1000);
return this.SendCommand(json);
}
public dynamic EnableNetwork()
{
json = #"{""id"":12345,""method"":""Network.enable""}";
Thread.Sleep(1000);
return this.SendCommand(json);
}
This is some code I had lying around.
I was very bored one day and decided to reinvent the wheel with Chrome automation. Basically - this code is how you could automate Chrome without using Selenium at all.
It does have a dependency on WebSockets4Net
But that being said - it could probably be refactored to use TcpClient.
All the commands that are issued to Chrome, are done in the form of a json request.
Eg: the following json command would tell chrome to execute the following javascript - essentially navigating to the url provided.
{
"method": "Runtime.evaluate",
"params": {
"expression": "document.location='urlhere'",
"objectGroup": "console",
"includeCommandLineAPI": true,
"doNotPauseOnExceptions": false,
"returnByValue": false
},
"id": 1
}
public dynamic SendCommand(string cmd)
{
if (EventHandler == null)
{
EventHandler = new Events();
EventHandler.OnNavigateStart += new Events.OnPageNavigateStart(EventHandler_OnNavigateStart);
EventHandler.OnNavigateEnd += new Events.OnPageNavigateEnded(EventHandler_OnNavigateEnd);
}
WebSocket4Net.WebSocket j = new WebSocket4Net.WebSocket(this.sessionWSEndpoint);
ManualResetEvent waitEvent = new ManualResetEvent(false);
ManualResetEvent closedEvent = new ManualResetEvent(false);
dynamic message = null;
byte[] data;
Exception exc = null;
j.Opened += delegate(System.Object o, EventArgs e)
{
j.Send(cmd);
};
j.MessageReceived += delegate(System.Object o, WebSocket4Net.MessageReceivedEventArgs e)
{
message = e.Message;
EventHandler.ParseEvents(e);
waitEvent.Set();
};
j.Error += delegate(System.Object o, SuperSocket.ClientEngine.ErrorEventArgs e)
{
exc = e.Exception;
waitEvent.Set();
};
j.Closed += delegate(System.Object o, EventArgs e)
{
closedEvent.Set();
};
j.DataReceived += delegate(object sender, WebSocket4Net.DataReceivedEventArgs e)
{
data = e.Data;
waitEvent.Set();
};
j.Open();
waitEvent.WaitOne();
if (j.State == WebSocket4Net.WebSocketState.Open)
{
j.Close();
closedEvent.WaitOne();
j = null;
}
if (exc != null)
throw exc;
serializer = null;
serializer = new JavaScriptSerializer();
serializer.RegisterConverters(new[] { converter });
dynamic obj = serializer.Deserialize(message, typeof(object));
message = null;
data = null;
return obj;
}
To demonstrate how this could be used practically - you can implement page-object and create 'types' that encapsulate objects on screen.
For instance:
public class Link : Base.Element
{
public Link(string XPath)
{
this.XPath = String.Copy(XPath);
}
/// <summary>
/// Overriding it - just in case we need to handle clicks differently
/// </summary>
/// <returns></returns>
public virtual bool Click()
{
Sync();
Console.WriteLine(Chrome.Driver.Eval("document.evaluate('" + XPath.Replace("'", "\\\\'") + "', document.documentElement, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null ).snapshotItem(0).click();"));
return true;
}
public virtual bool WaitForExistance(int iTimeout)
{
return base.WaitForExistance(iTimeout);
}
public virtual bool Exists()
{
return base.Exists();
}
public virtual string GetText()
{
Sync();
dynamic dval = Chrome.Driver.Eval("document.evaluate('" + XPath.Replace("'", "\\\\'") + "', document.documentElement, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null ).snapshotItem(0).innerText");
return dval.result.result.value;
}
}
Be warned - there were memory leaks in WebSockets4Net when I was using this code - so the application eventually had to be restarted.
Perhaps if WebSockets4Net is removed and replaced - it will work better.

How would I download a file from media fire in C # using webclient?

I am using a webclient to download a file from media fire but the download link changes every few days and it only works on my computer. I don't want to have to use some kind of API or anything because it shoudl be a simple process. I've considered other sites but none of them give me a direct download link to this. Here's my code:
public void downloadMod(string url, string location, string destination)
{
this.location = location;
this.destination = destination;
using (WebClient webClient = new WebClient()) {
Show();
webClient.DownloadFileCompleted += new AsyncCompletedEventHandler(onModDownloadCompleted);
webClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(onModDownloadProgressChanged);
Uri URL = url.StartsWith("http://", StringComparison.OrdinalIgnoreCase) ? new Uri(url) : new Uri("http://" + url);
try
{
webClient.DownloadFileAsync(URL, location);
}
catch (Exception ex)
{
Console.Write(ex.Message);
Close();
}
}
}
private void onModDownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
lblProgress.Text = e.ProgressPercentage.ToString() + " %";
progress.Value = e.ProgressPercentage;
}
private void onModDownloadCompleted(object sender, AsyncCompletedEventArgs e)
{
unZipFile(location, destination);
}
Help would be appreciated

Why don't you want to use the API that Media Fire seems to provide for exactly what you want to do? Just browsing through the API, there is a call to get the download link you are looking for. Suppose you somehow can figure out today how the download link is generated, what happens tomorrow when Media Fire changes the way it generates those links? Your code probably no longer works. If you use their API, it should work regardless of what changes they make.

jabber-net onAuthenticated doesn't get called

I am using jabber-net as my xmpp chat client with C# application. Chat server I am using is apache vysper 0.7
I created chat client using following code.
private void ChatOne_Load(object sender, EventArgs e)
{
JID jid = new JID("user1#test.com");
this.chatOneJabberClient.User = jid.User;
this.chatOneJabberClient.Server = jid.Server;
this.chatOneJabberClient.Password = "password1";
//this.chatOneJabberClient.AutoPresence = false;
//this.chatOneJabberClient.AutoRoster = false;
//this.chatOneJabberClient.AutoReconnect = -1;
this.chatOneJabberClient.OnAuthenticate += chatOneJabberClient_OnAuthenticate;
this.chatOneJabberClient.OnError += chatOneJabberClient_OnError;
this.chatOneJabberClient.OnReadText += chatOneJabberClient_OnReadText;
this.chatOneJabberClient.OnWriteText += chatOneJabberClient_OnWriteText;
this.chatOneJabberClient.Connect();
this.chatOneJabberClient.Login();
//done.WaitOne();
}
But what i understand from docs give over here is once the client is connected and login method is called it will automatically call the handler for OnAuthenticate.
When I try to send the message
private void button1_Click(object sender, EventArgs e)
{
this.chatOneJabberClient.Message("user2#test.com", this.textBox2.Text);
this.textBox2.Clear();
}
It throws and invalid operation exception. User must be authenticated first.
Do let me know if you want any other information.
When jabberClient starts it calls the OnWriteText methoda handler and I can see following thing in my chat box:
Send: <stream:stream xmlns:stream="http://etherx.jabber.org/streams" id="cb7f31d2" xmlns="jabber:client" to="test.com" version="1.0">
Do let me know if you need any further info.

I figured out the issue.
The problem was with my chat server. I am using apache vysper. I was trying to use web-socket endpoint. In current version of vysper there is not much active development on web-socket. I changed it to TcpEndPoint and its all good. :)

asp.net (C#) Facebook GetInfo()

I am struggling to get off with ground with some Facebook dev work. All I want to do is retireve some user info for the logged in user. This is the code I got from another site & it looks fine to me, however is always returns IsConnected() to be false.
I am running this code within an iframe on my facebook app (in sandbox mode)
private const string APPLICATION_KEY = "xxxxxxxxxxxxxxxxxxxxxxxxx";
private const string SECRET_KEY = "xxxxxxxxxxxxxxxxxxxxxxxxxx";
public Facebook.Rest.Api Api;
private Facebook.Session.ConnectSession _connectSession;
protected void Page_Load(object sender, EventArgs e)
{
_connectSession = new Facebook.Session.ConnectSession(APPLICATION_KEY,SECRET_KEY);
if (!_connectSession.IsConnected())
{
lit.Text = "Please sign-in with Facebook.";
}
else
{
try
{
Api = new Facebook.Rest.Api(_connectSession);
Facebook.Schema.user u = Api.Users.GetInfo();
img.ImageUrl = u.pic_square;
lit.Text = string.Format("Welcome, " + u.name);
}
catch (Exception ex)
{
lit.Text = ex.Message;
}
}
}

See this other SO question about a similar problem. The poster apparently found what he was looking for, but didn't know how to implement it. You may be able to do so, since there's a lot of information in the question body.
