Multiple sockets override itself

My Code
I want to make a multiple connection to a telnet console. This project is for Teamspeak and Teamspeak just communicate with telnet. I´ve a object that create a telnet connection as socket with the net lib. If we have just one instance to connect all works fine and I get the serverlist over the telnet connection back. But if I´ve two instance he says invalid loginname or password. That login informations are correct and he also try just to connect to one server.
My Class:
/*

How I open the class
if I call example one all works fine but example two has the descriped error.
Example 1:
test1 = new TeamspeakQueryClient({
"alias": "First-Coder Testinsance",
"ip": "first-coder.de",
"port": 10011,
"client": "serveradmin",
"password": "SECURE"
});
Example 2:
test1 = new TeamspeakQueryClient({
"alias": "First Insance",
"ip": "HIDDEN",
"port": HIDDEN,
"client": "serveradmin",
"password": "SECURE"
});
test2 = new TeamspeakQueryClient({
"alias": "Second Instance",
"ip": "HIDDEN",
"port": HIDDEN,
"client": "serveradmin",
"password": "SECURE"
});
Screenshots
Picture of the error in the console

According to your error, your second instance is not sending the correct login:
error id=520 msg=invalid\sloginname\sor\spassword
The additional errors displayed are due to your code not handling errors correctly.
For example:
socket.on("connect", function() {
...
if(err === null) {
if(err.id === 3329) {
If err === null, why would err have an element id?
Most likely this is code error, and you actually meant err !== null
$this.SendCommand("serverlist", null, function(err, response, rawResponse){
console.log(response);
if(response[0] === undefined) {
This error triggers because the (above) previous error was not caught.
At this point, the client is not logged in (authorized).
So when the serverlist command is sent, it riggers another error.
This additional error is also no handled, instead response is immediately used.

A console application to get a web page resource, using c# (javascript may cause this)

Aim: To download a website source with using a console application. You can find the used class in the program below.
Question: I use the code below to download a data (source) of a web page. Imagine you use chrome; If you enter first this query string, the web page itself redirects you a view HTML page and you see the data.
Entering this URL, to show the results it redirects itself to second page below. I make it by using javascript.
www.xyz.com/aaa.html?search=aaa&id=1
it redirects here: www.xyz.com/ViewResult.html
In an explorer, It works fine . I see 4 HTML tables inside the page when I use google chrome view source option. Bu in my application I see only two tables of the 4 . The two tables inside the web page is missing.(the missing two tables are the second and third.)
How can I overcome to this problem? I want to get the source of the page as I see in chrome.
Bonus informations: There is no iframe.
The particular Code :
string url = "www.xyz.com/aaa.html?search=aaa&id=1";

Interaction in a Dynamic action between javascript and plsql tasks

I'm trying to execute several pl/sql blocks in a Dynamic Action, with feedback to the end user with a modal dialog reporting the current satus.
Something like:
Processing Step 1...
/*Run pl/sql code for step 1*/
Processing Step 2...
/*Run pl/sql code for Step 2*/
and so on...
Both, the pl/sql and javascript code, run as intended but when I combined them on a Dynamic Action in the sequence:
1 - Execute Javascript
2 - Execute PL/SQL block /* With wait for result option checked*/
3 - Execute Javascript
4 - Execute PL/SQL block
The status dialog is not been shown, however the pl/sql blocks are completed without problems.
I realize that this must be something related to javascript not been multithreaded, so I've moved the pl/sql block to application processes and run them as ajax calls like this:
function something(){
var get;
var result = 0;
updateStatus('Running Step1');
get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=P6_STEP_1',0);
result = get.get();
if(result > 0){
updateStatus('Running Step 2');
get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=P6_STEP_2',0);
result = get.get();
}
closeStatusDialog();
}
But still, as before, the processes run fine but the dialog doesn't appear. Finally I added a setTimeOut function to each call, like this:
function something(){
var get;
var result = 0;
updateStatus('Running Step1');
get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=P6_STEP_1',0);
result = setTimeOut(get.get(),500);
if(result > 0){
updateStatus('Running Step 2');
get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=P6_STEP_2',0);
result = setTimeOut(get.get(),500);
}
closeStatusDialog();
}
But still nothing. What can I do to get this running as needed?.
I've checked the browser console and no exeptions are been thrown, likewise with the pl/sql blocks.

I've solved it, although the solution doesn't rely on dynamic actions, just javascript and applicacion processes. I'm posting this for anyone with a similar problem.
The htmldb_Get Javascript object is an oracle-apex wrapper for the XMLHttpRequest AJAX object. Poorly documented though.
I've found a copy of the code (at the bottom) and it turns out it has another function called GetAsync that allows to pass a function as a parameter to asign it to the onreadystatechange attribute on the XMLHttpRequest object, which will be executed each time the attribute readyState of the underlying XMLHttpRequest changes.
The function passed as a parameter can't have parameters on its own definition.
So, instead of calling get() on the htmldb_Get object you need to call GetAsync(someFunction)
With this solution in my case:
function something(){
var get;
get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=P6_STEP_1',0);
get.GetAsync(someFunctionStep1);
}
function someFunctionStep1(){
if(p.readyState == 0){ /*p is the underlying XMLHttpRequest object*/
console.log("request not initialized");
updateStatus('Running Step 1');
} else if(p.readyState == 1){
console.log("server connection established");
} else if(p.readyState == 2){
console.log("request received");
} else if(p.readyState == 3){
console.log("processing request");
} else if(p.readyState == 4){
console.log("request finished and response is ready");
callStep2();
}
}
function callStep2(){
var get;
get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=P6_STEP_2',0);
get.GetAsync(someFunctionStep2);
}
function someFunctionStep2(){
if(p.readyState == 0){
console.log("request not initialized");
updateStatus('Running Step 2');
} else if(p.readyState == 1){
console.log("server connection established");
} else if(p.readyState == 2){
console.log("request received");
} else if(p.readyState == 3){
console.log("processing request");
} else if(p.readyState == 4){
console.log("request finished and response is ready");
closeDialog();
}
}

Gettings response (headers and body) in firefox extension

I'm trying to implement a feature that will give me the response text and (all the) response headers of each http request in the browser,
I've read a bit here: http://www.softwareishard.com/blog/firebug/nsitraceablechannel-intercept-http-traffic/
I had no idea how to extract the response from the TracingListener object. Anyone dealt with that before?? thanks!
My code:
const Cc = Components.classes;
const Ci = Components.interfaces;
// Helper function for XPCOM instanciation (from Firebug)
function CCIN(cName, ifaceName) {
return Cc[cName].createInstance(Ci[ifaceName]);
}
// get the observer service and register for the two coookie topics.
var observerService = Components.classes["#mozilla.org/observer-service;1"]
.getService(Components.interfaces.nsIObserverService);
// Copy response listener implementation.
function TracingListener() {
this.originalListener = null;
this.receivedData = []; // array for incoming data.
}
TracingListener.prototype =
{
originalListener: null,
receivedData: null, // array for incoming data.
onDataAvailable: function(request, context, inputStream, offset, count)
{
var binaryInputStream = CCIN("#mozilla.org/binaryinputstream;1",
"nsIBinaryInputStream");
var storageStream = CCIN("#mozilla.org/storagestream;1", "nsIStorageStream");
binaryInputStream.setInputStream(inputStream);
storageStream.init(8192, count, null);
var binaryOutputStream = CCIN("#mozilla.org/binaryoutputstream;1",
"nsIBinaryOutputStream");
binaryOutputStream.setOutputStream(storageStream.getOutputStream(0));
// Copy received data as they come.
var data = binaryInputStream.readBytes(count);
this.receivedData.push(data);
binaryOutputStream.writeBytes(data, count);
this.originalListener.onDataAvailable(request, context,storageStream.newInputStream(0), offset, count);
},
onStartRequest: function(request, context) {
this.originalListener.onStartRequest(request, context);
},
onStopRequest: function(request, context, statusCode)
{
try {
if (request.originalURI && piratequesting.baseURL == request.originalURI.prePath && request.originalURI.path.indexOf("/index.php?ajax=") == 0) {
dump("\nProcessing: " + request.originalURI.spec + "\n");
var date = request.getResponseHeader("Date");
var responseSource = this.receivedData.join();
dump("\nResponse: " + responseSource + "\n");
piratequesting.ProcessRawResponse(request.originalURI.spec, responseSource, date);
}
} catch(e) { dumpError(e);}
this.originalListener.onStopRequest(request, context, statusCode);
},
QueryInterface: function (aIID) {
if (aIID.equals(Ci.nsIStreamListener) ||
aIID.equals(Ci.nsISupports)) {
return this;
}
throw Components.results.NS_NOINTERFACE;
}
}
// create an nsIObserver implementor
var listener = {
observe : function(aSubject, aTopic, aData) {
// Make sure it is our connection first.
//if (aSubject == gChannel) {
var httpChannel = aSubject.QueryInterface(Components.interfaces.nsIHttpChannel);
if (aTopic == "http-on-modify-request") {
// ...
httpChannel.setRequestHeader("X-Hello", "World", false);
} else if (aTopic == "http-on-examine-response") {
// ...
//alert(JSON.stringify(aData));
var newListener = new TracingListener();
aSubject.QueryInterface(Ci.nsITraceableChannel);
newListener.originalListener = aSubject.setNewListener(newListener);
alert(httpChannel.getResponseHeader("Location"));
//alert(httpChannel.getAllResponseHeaders());
}
//}
},
QueryInterface : function(aIID) {
if (aIID.equals(Components.interfaces.nsISupports) ||
aIID.equals(Components.interfaces.nsIObserver))

WinRT - StreamSocket - Connection closing while reading data via LoadAsync

I'm trying to send HTTP requests via StreamSocket, but response is truncated with
"failedWinRTError: The object has been closed."
Here is my code:
var count, hostName, raw_request, raw_response, reader, socketProtection, startReader, streamSocket, writer;
streamSocket = new Windows.Networking.Sockets.StreamSocket();
hostName = new Windows.Networking.HostName("www.reddit.com", "80");
raw_response = "";
count = 0;
startReader = function() {
return reader.loadAsync(8 * 1000).done(function(bytesRead) {
raw_response += reader.readString(reader.unconsumedBufferLength);
if (raw_response.indexOf("</html>") > 0) {
return;
} else {
startReader();
}
}, function(error) {
raw_response += reader.readString(reader.unconsumedBufferLength);
window.raw_response = raw_response;
return;
});
};
streamSocket.connectAsync(hostName, "80", 0).done(function(response) {
var string;
reader = new Windows.Storage.Streams.DataReader(streamSocket.inputStream);
reader.inputStreamOptions = 1;
writer = new Windows.Storage.Streams.DataWriter(streamSocket.outputStream);
string = "Hello world";
writer.writeString(raw_request);
return writer.storeAsync().done(function() {
writer.flushAsync();
writer.detachStream();
return startReader();
});
});
I noticed that the beginning of the response is truncated as well.
This is what I get at the beginning of HTTP responses.
/1.1 200 OK
Also strangely... HTTPS requests work perfectly.
Any idea what I'm doing wrong? Thanks :)

Remove http:// from the host name and the second parameter is not needed:
var hostName = new Windows.Networking.HostName("www.reddit.com");
Use this object in ConnectAsync, just hostname and service name parameters are needed:
streamSocket.connectAsync(hostName, "80").done(function (response) {
// ....
}, function (error) {
console.log(error);
});
UPDATE: Ok, if the connection is being closed, probably the server closes it. Are you sending a well formed request? Here is an example:
var raw_request, raw_response, reader, writer;
var streamSocket = new Windows.Networking.Sockets.StreamSocket();
function doRequest() {
var hostName = new Windows.Networking.HostName("www.reddit.com");
streamSocket.connectAsync(hostName, "808").then(function () {
reader = new Windows.Storage.Streams.DataReader(streamSocket.inputStream);
reader.inputStreamOptions = Windows.Storage.Streams.InputStreamOptions.partial;
writer = new Windows.Storage.Streams.DataWriter(streamSocket.outputStream);
raw_request = "GET / HTTP/1.1\r\nHost: www.reddit.com/\r\nConnection: close\r\n\r\n";
writer.writeString(raw_request);
return writer.storeAsync();
}).then(function () {
raw_response = "";
return startReader();
}, function (error) {
console.log(error);
});
}
function startReader() {
return reader.loadAsync(99999999).then(function (bytesRead) {
raw_response += reader.readString(reader.unconsumedBufferLength);
if (bytesRead === 0) {
window.raw_response.value = raw_response;
return;
}
return startReader();
});
};
