Hi I have the following class which would like to replace with stjs, but it seems it does not work for me, as stjs does not cover all applet libraries, any though if this is can be done thru stjs or any other technology? Thanks in advance

I have a problem in sending file through webscoket in browser with js to c# server.
When I want to save the buffer, if it is a txt file, there is no problem
But if it is a photo, for example, the photo will not be opened after saving
Where am I going wrong?
private void BeginReceive()
{
try
{
Buffer = new byte[BufferSize];
Socket.BeginReceive(Buffer, 0, BufferSize, SocketFlags.None, new AsyncCallback(ReceiveCallback), this);
}
catch (SocketException ex)
{
Console.WriteLine("{0}: {1}", "BeginReceive", ex.Message);
Close();
}
catch (Exception ex)
{
Console.WriteLine("{0}: {1}", "BeginReceive", ex.Message);
}
}
private void ReceiveCallback(IAsyncResult ar)
{
try
{
if (CheckState(ar))
{
int bytesRead = Socket.EndReceive(ar);
Console.WriteLine("{0}: {1}", "bytesRead: ", bytesRead);
File.WriteAllText(#"c:\01.jpg", Helper.DecodedBytes(Buffer, bytesRead));
}
}
catch (SocketException)
{
Close();
}
catch (Exception ex)
{
Console.WriteLine("{0}: {1}", "ReceiveCallback", ex.Message);
}
finally
{
if(!Helper.SocketIsDisposed(Socket)) BeginReceive();
}
}
I think the problem is with the decode function
public static string DecodedBytes(byte[] buffer, int length)
{
if(buffer[0] == 136 && (buffer[1] == 130 || buffer[1] == 128)) throw new System.Net.Sockets.SocketException(10054); //[10054]: Connection reset by peer
byte b = buffer[1];
int dataLength = 0;
int totalLength = 0;
int keyIndex = 0;
if (b - 128 <= 125)
{
dataLength = b - 128;
keyIndex = 2;
totalLength = dataLength + 6;
}
if (b - 128 == 126)
{
dataLength = BitConverter.ToInt16(new byte[] { buffer[3], buffer[2] }, 0);
keyIndex = 4;
totalLength = dataLength + 8;
}
if (b - 128 == 127)
{
dataLength = (int)BitConverter.ToInt64(new byte[] { buffer[9], buffer[8], buffer[7], buffer[6], buffer[5], buffer[4], buffer[3], buffer[2] }, 0);
keyIndex = 10;
totalLength = dataLength + 14;
}
if (totalLength > length)
throw new Exception("The buffer length is small than the data length");
byte[] key = new byte[] { buffer[keyIndex], buffer[keyIndex + 1], buffer[keyIndex + 2], buffer[keyIndex + 3] };
int dataIndex = keyIndex + 4;
int count = 0;
for (int i = dataIndex; i < totalLength; i++)
{
buffer[i] = (byte)(buffer[i] ^ key[count % 4]);
count++;
}
return Encoding.UTF8.GetString(buffer, dataIndex, dataLength);
}
and js code:
connect:function(){
var root = this;
root.websocket = new WebSocket(root.url);
root.websocket.binaryType = "arraybuffer";
root.websocket.onopen = () => root.fireEvent('connect');
root.websocket.onmessage = (e) => {
root.fireEvent('receive',JSON.parse(e.data));
}
window.addEventListener("beforeunload", function() {
root.websocket.onclose = function () {};
root.websocket.close();
});
},
sendFile:function(){
var root = this;
var file = document.getElementById('filename').files[0];
var loader = new FileReader();
loader.onload = (e) => {
var a = e.target.result;
root.controller.websocket.send(e.target.result);
}
loader.readAsText(file)
},
Problem solved
JS code changed to:
sendFile:function(){
var root = this;
var file = document.getElementById('filename').files[0];
var loader = new FileReader();
loader.onload = (e) => {
var byteArray = new Uint8Array(e.target.result);
root.controller.websocket.send(byteArray.buffer);
}
loader.readAsArrayBuffer(file);
}
and C# code changed to:
WriteAllText to WriteAllBytes
File.WriteAllBytes(#"c:\01.jpg", Helper.DecodedBytes(Buffer, bytesRead));
and Encoding.Default.GetString(buffer, dataIndex, dataLength) to buffer.Skip(dataIndex).ToArray()
return buffer.Skip(dataIndex).ToArray();
I have the following as a string
var string = "#anno1[ data1 xyz #anno2[data2 #anno3[data3] data4] data5 #anno4[data6] data7]"
And I would like to convert it an object as follows:
var childs = [
{
name : '#anno1',
text : 'data1 xyz data2 data3 data4 data5 data6 data7',
},
{
name : '#anno2',
text : 'data2 data3 data4'
},
{
name : '#anno3',
text : 'data3'
},
{
name : '#anno4',
text : 'data6'
}
]
I've tried out many ways but I was not successful, thanks in advance.
Here is the java code which i have tried
import java.util.HashMap;
import java.util.Map;
public class ExpressionTree {
static Map <String, String> resultMap = new HashMap<String, String>(16);
public static void main(String args[]) {
// String exp = "[data1 xyz #anno2[data2 #anno3[data3] data4] data5 #anno4[data6] data7]";
String exp = "#anno1[ data1 xyz #anno2[data2 #anno3[data3] data4] data5 #anno4[data6] data7 ]";
parseRecursively(exp);
}
private static void parseRecursively(String exp) {
String annotation = null;
String annotationValue = null;
if (exp.startsWith("#")) {
int dataStartIndex = exp.indexOf("[");
annotation = exp.substring(0, dataStartIndex);
annotationValue = exp.substring(0 + dataStartIndex, exp.lastIndexOf("]")+1).trim();
System.out.println(annotation);
System.out.println(annotationValue);
resultMap.put(annotation, annotationValue);
parseRecursively(annotationValue);
} else {
int annotationStartIndex = exp.indexOf("#");
int dataStartIndex = exp.substring(1).indexOf("[");
if( -1 != annotationStartIndex || -1 != dataStartIndex)
{
annotation = exp.substring(annotationStartIndex, dataStartIndex+1).trim();
String nextData = exp.substring(0 + dataStartIndex + 1).trim();
String tmpNextData = nextData;
int countOfOpenBrackets = 0;
for (int i = 0; tmpNextData.charAt(i) != ']'; i++) {
// System.out.println(tmpNextData.charAt(i));
if (tmpNextData.charAt(i) == '[') {
countOfOpenBrackets++;
}
// tmpNextData = tmpNextData.substring(1);
}
tmpNextData = nextData;
int endIndexOfCurrentData = 0;
for (int i = 0; i < tmpNextData.length() && endIndexOfCurrentData == 0; i++) {
// System.out.println(tmpNextData.charAt(i));
if (tmpNextData.charAt(i) == ']') {
countOfOpenBrackets--;
}
if (countOfOpenBrackets == 0) {
endIndexOfCurrentData = i + 1;
}
// tmpNextData = tmpNextData.substring(1);
}
annotationValue = nextData.substring(0, endIndexOfCurrentData).trim();
System.out.println(annotation);
System.out.println(annotationValue);
resultMap.put(annotation, annotationValue);
parseRecursively(annotationValue);
}
}
System.out.println(resultMap);
}
}
Here is a JavaScript (ES6) solution:
function toObject(string) {
"use strict";
const tokens = string.match(/[\[\]]|[^\s\[\]]+/g),
result = [];
let i = 0;
function recurse() {
const words = [];
let obj;
while (i < tokens.length) {
let token = tokens[i];
if (token[0] === '#') {
obj = {name: token};
result.push(obj);
} else if (token === '[') {
i++;
obj.text = recurse();
words.push(obj.text);
} else if (token === ']') {
break;
} else {
words.push(token);
}
i++;
}
return words.join(' ');
}
recurse();
return result;
}
const string = "#anno1[ data1 xyz #anno2[data2 #anno3[data3] data4] data5 #anno4[data6] data7]";
const result = toObject(string);
console.log(result);

It's my first post on stackoverflow so I hope I won't make too many mistakes.
I've a problem with filling Java List and sending it to aui:select as options. My goal is to fill aui:select dynamically whenever one of their options is changed. For example: if you change first select item (county), second and third items (community and city respectively) are emptied and then filled with data dependent on selected county.
I've come to a conclusion that whenever there's a "mvcPath" parameter in Query String Parameters this code basically copies code from the whole page. This code works well whenever there's no "mvcPath" though. Sadly, I need this parameter to change pages (from search results to selected result details).
Image showing badly filled select item
Image showing correctly filled select item

After some changes in server-side code I managed to fix this issue. I'm not really sure how did as small changes as those helped but I'm happy to close this thread.
This is the server-side code:

I am using ReCaptcha with the javascript API on my aspx page on localhost. I read somewhere that I don't need a key as long as I use it on localhost. So, I use some random key that I found somewhere. I could render the recaptcha challenge successfully. The following is my javascript code.
Recaptcha.create("6Ld4iQsAAAAAAM3nfX_K0vXaUudl2Gk0lpTF3REf", 'captchadiv',
{
tabindex: 1,
theme: "clean",
callback: Recaptcha.focus_response_field
});
//To Validate user response
function Recaptcha_IsCorrect()
{
var xmlHttpRequest;
var PageURL = document.URL;
var xmlDoc;
if (window.XMLHttpRequest)
{
xmlHttpRequest = new XMLHttpRequest();
}
else
{
xmlHttpRequest = new ActiveXObject("Microsoft.xmlHttpRequest");
}
var challenge = Recaptcha.get_challenge();
var userResponse = Recaptcha.get_response();
var url = "../Ajax/PIAsyncAjax.asmx/ValidateReCaptcha?clientIP=127.0.0.1&privateKey=6Ld4iQsAAAAAAM3nfX_K0vXaUudl2Gk0lpTF3REf&challenge=" + challenge + "&response=" + userResponse;
xmlHttpRequest.open("GET", url);
xmlHttpRequest.onreadystatechange = function ()
{
if (xmlHttpRequest.readyState == 4 && xmlHttpRequest.status == 200)
{
alert(xmlHttpRequest.responseText);
}
};
xmlHttpRequest.send();
}
The following is my code for the webservice which exposed the webmethod to validate ReCaptcha user input. I get the error "invalid-site-private-key".

What am I doing wrong? Should I have to get a private key? Any help would be great.
Thanks in advance,
Venkat.
It works with the public and private keys that I just created. Damn, I just assumed, "localhost" would not be accepted as a legal domain-name while signing up.
This is my javascript code:
var bankOptions = {};
var playerOptions = [];
bankOptions["BankTotalAmount"] = $("#totalBankAmountID").val();
bankOptions["SinglePlayerAmount"] = $("#singlePlayerAmountID").val();
while (_playerNumber != 0) {
if (_playerNumber == 1) {
var player1Option = {};
player1Option["Name"] = $("#p" + _playerNumber + "Name").val();
player1Option["Color"] = $("#p" + _playerNumber + "Color").val();
playerOptions.push(player1Option);
}
if (_playerNumber == 2) {
var player2Option = {};
player2Option["Name"] = $("#p" + _playerNumber + "Name").val();
player2Option["Color"] = $("#p" + _playerNumber + "Color").val();
playerOptions.push(player2Option);
}
if (_playerNumber == 3) {
var player3Option = {};
player3Option["Name"] = $("#p" + _playerNumber + "Name").val();
player3Option["Color"] = $("#p" + _playerNumber + "Color").val();
playerOptions.push(player3Option);
}
if (_playerNumber == 4) {
var player4Option = {};
player4Option["Name"] = $("#p" + _playerNumber + "Name").val();
player4Option["Color"] = $("#p" + _playerNumber + "Color").val();
playerOptions.push(player4Option);
}
_playerNumber--;
}
alert(playerOptions);
$.ajax({
url: "/StartOption/setOptions/",
contentType: 'application/json',
data: JSON.stringify({ bankOptions: bankOptions, playerOptions: playerOptions }),
type: "POST",
timeout: 10000,
success: function (result) {
}
});
and i have this Controller class
public class StartOptionController : Controller
{
private MonopolyDB db = new MonopolyDB();
//
// GET: /StartOption/
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult setOptions(BankOptions bankOptions, Playeroptions[] playerOptions)
{
//int length = (int)playerOptions.GetType().InvokeMember("length", BindingFlags.GetProperty, null, playerOptions, null);
BankAccount bankaccount = new BankAccount();
bankaccount.ID = 1;
bankaccount.TotalAmmount = bankOptions.BankTotalAmount;
db.BankAccount_Table.Add(bankaccount);
db.SaveChanges();
//Here i want to get each (player1Option, player2Option...) object array from that playerOptions object array
//return RedirectToAction("Index");
return View();
}
}
public class BankOptions
{
public int BankTotalAmount { get; set; }
public int SinglePlayerAmount { get; set; }
}
public class Playeroptions
{
public string Name { get; set; }
public string Color { get; set; }
}
My question is how i can get those object array that i push into playerOptions object array in my setOptions action?
as like i want to save each player info in my DB from playerOptions object array where i push each player info in my javascript code.
Well first to make it easy I would like to recommend that changes the sign of your action
from
public ActionResult setOptions(BankOptions bankOptions, Playeroptions[] playerOptions)
To
public ActionResult setOptions(BankOptions bankOptions, List<PlayerOptions> playerOptions)
That's it's going to make it easy the handle of each element of the array, and there's not problem for the framework to serialize this object.
Now to answer your question you could iterate the array like this
[HttpPost]
public ActionResult setOptions(BankOptions bankOptions, Playeroptions[] playerOptions)
{
//int length = (int)playerOptions.GetType().InvokeMember("length", BindingFlags.GetProperty, null, playerOptions, null);
BankAccount bankaccount = new BankAccount();
bankaccount.ID = 1;
bankaccount.TotalAmmount = bankOptions.BankTotalAmount;
db.BankAccount_Table.Add(bankaccount);
db.SaveChanges();
//Here i want to get each (player1Option, player2Option...) object array from that playerOptions object array
for ( int i = 0 ; i< playerOptions.Length, i++)
{
playerOptions[i]; //<-- this give's the specific element
}
//return RedirectToAction("Index");
return View();
}
Nevertheless if you follow my recommendation and changes the sign of your action you could iterate your code like this
[HttpPost]
public ActionResult setOptions(BankOptions bankOptions, List<PlayerOptions> playerOptions)
{
//int length = (int)playerOptions.GetType().InvokeMember("length", BindingFlags.GetProperty, null, playerOptions, null);
BankAccount bankaccount = new BankAccount();
bankaccount.ID = 1;
bankaccount.TotalAmmount = bankOptions.BankTotalAmount;
db.BankAccount_Table.Add(bankaccount);
db.SaveChanges();
//Here i want to get each (player1Option, player2Option...) object array from that playerOptions object array
foreach( var item in playerOptions){
item //<--- in this variable you have the element PlayerOption
}
//return RedirectToAction("Index");
return View();
}
