• Android Reading from an Input stream efficiently

  - by RenegadeAndy

  Hey, I am making an HTTP get request to a website for an android application I am making. I am using a DefaultHttpClient and using HttpGet to issue the request. I get the entity response and from this obtain an InputStream object for getting the html of the page. I then cycle through the reply doing as follows: BufferedReader r = new BufferedReader(new InputStreamReader(inputStream)); String x = ""; x = r.readLine(); String total = ""; while(x!= null){ total += x; x = r.readLine(); } However this is horrendously slow. Is this inefficient? I'm not loading a big web page - www.cokezone.co.uk so the file size is not big. Is there a better way to do this? Thanks Andy

• Can't seem to get Prototype AJAX form validation to work in conjunction with Codeigniter

  - by MattB

  Is there some kind of trick involved? Here's how I would envision it working: 1) User tries submitting the form 2) Event.observe captures this and sends an AJAX request to a special validation URL (PHP using Codeigniter) 3) If no errors were returned, continue submitting the original form 4) If errors were found, cancel form submission and display Mostly, I can't seem to get a separate AJAX validation request to work as the form continues submitting. I could use Event.stop(event), but have not found a way to re-start the process if no validation errors exist from the validation call. I'd post code, but I have about 15 examples of things I've tried and it would just clutter this question. Any ideas? :-( I didn't think form validation would be this difficult. Many thanks, - Matt

• Help with calling a secure (SSL) webservice in Android.

  - by mmattax

  I'm new to Android and am struggling to make a call to an SSL web service for an Android Application. My code is as follows: Log.v("fs", "Making HTTP call..."); HttpClient http = new DefaultHttpClient(); HttpGet request = new HttpGet("https://example.com/api"); try { String response = http.execute(request, new BasicResponseHandler()); Log.v("fs", response); } catch (Exception e) { Log.v("fs", e.toString()); } The Output is: Making HTTP call... javax.net.SSLPeerUnverifiedException: No peer certificate Any suggestions to make this work would be great. EDIT I should note that this is a valid cert. It is not self-signed.

• How to grant permissions to single SELECT/UPDATE statment (sql server) ?

  - by Albert

  I have a problem when trying to execute this update statement (below) using C# SqlCommand when I execute it locally it works fine, but when deployed to another machine I got a permission error The SELECT permission was denied on the object Order ... The UPDATE permission was denied on the object Order ... Update Statement "UPDATE Order SET Request = @request WHERE Id = @ID"; Is there any way to add GRANT SELECT and GRANT UPDATE to a single statement like the update above without using a stored procedure? or the SP is the way to go on this? Thanks in advance

• check if directory exists c#

  - by Ant

  I am trying to see if a directory exists based on an input field from the user. When the user types in the path, I want to check if the path actually exists. I have some c# code already. It returns 1 for any local path, but always returns 0 when I am checking a network path. static string checkValidPath(string path) { //Insert your code that runs under the security context of the authenticating user here. using (ImpersonateUser user = new ImpersonateUser(user, "", password)) { //DirectoryInfo d = new DirectoryInfo(quotelessPath); bool doesExist = Directory.Exists(path); //if (d.Exists) if(doesExist) { user.Dispose(); return "1"; } else { user.Dispose(); return "0"; } } } public class ImpersonateUser : IDisposable { [DllImport("advapi32.dll", SetLastError = true)] private static extern bool LogonUser(string lpszUsername, string lpszDomain, string lpszPassword, int dwLogonType, int dwLogonProvider, out IntPtr phToken); [DllImport("kernel32", SetLastError = true)] private static extern bool CloseHandle(IntPtr hObject); private IntPtr userHandle = IntPtr.Zero; private WindowsImpersonationContext impersonationContext; public ImpersonateUser(string user, string domain, string password) { if (!string.IsNullOrEmpty(user)) { // Call LogonUser to get a token for the user bool loggedOn = LogonUser(user, domain, password, 9 /*(int)LogonType.LOGON32_LOGON_NEW_CREDENTIALS*/, 3 /*(int)LogonProvider.LOGON32_PROVIDER_WINNT50*/, out userHandle); if (!loggedOn) throw new Win32Exception(Marshal.GetLastWin32Error()); // Begin impersonating the user impersonationContext = WindowsIdentity.Impersonate(userHandle); } } public void Dispose() { if (userHandle != IntPtr.Zero) CloseHandle(userHandle); if (impersonationContext != null) impersonationContext.Undo(); } } Any help is appreciated. Thanks! EDIT 3: updated code to use BrokenGlass's impersonation functions. However, I need to initialize "password" to something... EDIT 2: I updated the code to try and use impersonation as suggested below. It still fails everytime. I assume I am using impersonation improperly... EDIT: As requested by ChrisF, here is the function that calls the checkValidPath function. Frontend aspx file... $.get('processor.ashx', { a: '7', path: x }, function(o) { alert(o); if (o=="0") { $("#outputPathDivValid").dialog({ title: 'Output Path is not valid! Please enter a path that exists!', width: 500, modal: true, resizable: false, buttons: { 'Close': function() { $(this).dialog('close'); } } }); } }); Backend ashx file... public void ProcessRequest (HttpContext context) { context.Response.Cache.SetExpires(DateTime.Now); string sSid = context.Request["sid"]; switch (context.Request["a"]) {//a bunch of case statements here... case "7": context.Response.Write(checkValidPath(context.Request["path"].ToString())); break;

• Why does Java force user-agent through simple Socket IO?

  - by Zombies

  I am using nothing but raw Socket IO. There isn't one HttpURLConnection nor any http client libs in my project. When I run it through wireshark I see somethign very revealing: GET / HTTP/1.1 User-Agent: Java/1.6.0_15 Host: www.google.com Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 Connection: keep-alive Here is the crazy part, I never put ANY of that in my original request. My original request was: "GET http://www.google.com/ HTTP/1.1\r\n" + "Host: www.google.com\r\n" + "User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.8) Gecko/20100214 Ubuntu/9.10 (karmic) Firefox/3.5.8\r\n" + "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n" + "Accept-Language: en-us,en;q=0.5\r\n" + "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7\r\n" + "Keep-Alive: 300\r\n" + "\r\n"; I am using the default Sun JVM.

• Java threads, wait time always 00:00:00-Producer/Consumer

  - by user3742254

  I am currently doing a producer consumer problem with a number of threads and have had to set priorities and waits to them to ensure that one thread, the security thread, runs last. I have managed to do this and I have managed to get the buffer working. The last thing that I am required to do is to show the wait time of threads that are too large for the buffer and to calculate the average wait time. I have included code to do so, but everything I run the program, the wait time is always returned as 00:00:00, and by extension, the average is returned as the same. I was speaking to one of my colleagues who said that it is not a matter of the code but rather a matter of the computer needing to work off of one processor, which can be adjusted in the task manager settings. He has an HP like myself but his program prints the wait time 180 times, whereas mine prints usually about 3-7 times and is only 00:00:01 on one instance before finishing when I have made the processor adjustments. My other colleague has an iMac and hers puts out an average of 42:00:34(42 minutes??) I am very confused about this because I can see no difference between our codes and like my colleague said, I was wondering is it a computer issue. I am obviously concerned as I wanted to make sure that my code correctly calculated an average wait time, but that is impossible to tell when the wait times always show as 00:00:00. To calculate the thread duration, including the time it entered and exited the buffer was done by using a timestamp import, and then subtracting start time from end time. Is my code correct for this issue or is there something which is missing? I would be very grateful for any solutions. Below is my code: My buffer class package com.Com813cw; import java.text.DateFormat; import java.text.SimpleDateFormat; /** * Created by Rory on 10/08/2014. */ class Buffer { private int contents, count = 0, process = 200;

• setting a timeout for an InputStreamreader variable

  - by Noona

  I have a server running that accepts connections made through client sockets, I need to read the input from this client socket, now suppose the client opened a connection to my server without sending anything through the server's socket outputstream, in this case, while my server tried to read the input through the client socket's inputstream, an exception will be thrown, but before the exception is thrown i would like a timeout say of 5 sec, how can I do this? currently here's how my code looks like on the server side: try { InputStreamReader clientInputStream = new InputStreamReader(clientSocket.getInputStream()); int c; StringBuffer requestBuffer = new StringBuffer(); while ((c = clientInputStream.read()) != -1) { requestBuffer.append((char) c); if (requestBuffer.toString().endsWith(("\r\n\r\n"))) break; } request = new Request(requestBuffer.toString(), clientSocket); } catch (Exception e) // catch any possible exception in order to keep the thread running { try { if (clientSocket != null) clientSocket.close(); } catch (IOException ex) { ex.printStackTrace(); } System.err.println(e); //e.printStackTrace(); }

• Why does firefox round-trip to the server to determine whether my files are modifed?

  - by erikkallen

  I have some static content on my web site that I have set up caching for (using Asp.NET MVC). According to Firebug, the first time I open the page, Firefox sends this request: GET /CoreContent/Core.css?asm=0.7.3614.34951 Host: 127.0.0.1:3916 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729) Accept: text/css,*/*;q=0.1 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Referer: http://127.0.0.1:3916/Edit/1/101 Cookie: .ASPXAUTH=52312E5A802C1A079E2BA29AA2BFBC5A38058977B84452D62ED52855D4164659B4307661EC73A307BFFB2ED3871C67CB3A9AAFDB3A75A99AC0A21C63A6AADE9A11A7138C672E75125D9FF3EFFBD9BF62 Pragma: no-cache Cache-Control: no-cache Which my server replies to with this: Server: ASP.NET Development Server/9.0.0.0 Date: Mon, 23 Nov 2009 18:44:41 GMT X-AspNet-Version: 2.0.50727 X-AspNetMvc-Version: 1.0 Cache-Control: public, max-age=31535671 Expires: Tue, 23 Nov 2010 18:39:12 GMT Last-Modified: Mon, 23 Nov 2009 18:39:12 GMT Vary: * Content-Type: text/css Content-Length: 15006 Connection: Close So far, so good.

Why does Firefox issue this second request? In the first response, I said that the cache does not expire for a year (I intend to use query parameters whenever things change). Do I have to add another response header to prevent this extra roundtrip? Edit: It does not matter whether I press refresh, or whether I go to the page again (or a different URL, which references the same external files). Firefox does the same again. Also, I don't claim this to be a bug in FF, I just wonder if there is another header I can set which means "This document will never change, don't bother me again".

• Modal dialog blocks wcf callback

  - by Bjarne

  I am working on an application that relies strongly on a wcf request/callback pattern. That is, it uses a service which exposes a number of methods, and for each method there is a callback on which the result is returned. In the client, I wish to open a modal dialog, make a request on the server and then wait for the result on the callback. But I never get a callback since the UI thread is blocked by the modal dialog. Has anyone worked with a similar pattern? I would hate to have more threads in the client, and I also don't like the idea of 'simulating' a modal dialog.

• get data from asp page

  - by sam

  I am wondering if there is anyway to grab the html that is generated from an ASP page. I am trying to pull a table from the page, and I foolishly used a static html page so I would not have to be constantly querying the server where this page resides while I tested out my code. The javascript code I wrote to grab to unlabeled table from the page works. Then when I put it into practice with the real page and found that the ASP page does not generate a viewable page with a jquery .get request on the URL. Is there any way to query the page for the table I need so that the ASP page returns a valid page on request? (I am also limited to using javascript and perl for this, the server where this will reside will not run php and I have no desire to learn ASP.NET to solve this by adding to the issue of proprietary software)

• Get wrong PATH_INFO after rewriting in lighttpd

  - by Satoru.Logic

  In my lighttpd config file, I have a rewrite rule like this: $HTTP["host"] == "sub.example.com" { url.rewrite = ( "^/(.*)" => "/sub/$1" ) } So when a user visits http://sub.example.com, she's actually visiting http://example.com/sub. The problem is that the PATH_INFO seems wrong, URL: http://sub.example.com/extra PATH_INFO: expected: /extra what I get: /sub/extra Now whenever I call request.get_path(), it returns something like http://sub.example.com/sub/extra, which is not what I want. Of course, I can just override the get_path method of the request class, but I wonder if there is a simpler way like changing the lighttpd config?

• Windows Phone 7 HttpRequest Unable to see true Error Code and response details

  - by Bob

  I have to call a somewhat broken API from a Windows Phone 7 application. The API returns a 302 error and a cookie to the authentication request. I've tried every way I've been able to find in the MSDN documentation for using ClientHTTP instead of BrowserHTTP (registering the prefix, using the call to explicitly create a ClientHTTP using Request), but the 302 is getting translated to a 404 and I'm not seeing the cookies on the response. I've tried a WebClient, I've tried an HttpRequest and it is always the translated error message. If I allocate a CookieContainer for the HttpRequest, I get a null argument exception when the client stack is parsing the returned message. I can see that the response is coming back as expected via Fiddler.

• Generating PDF's via Delayed Job while maintaing a RESTful pattern.

  - by Jeff

  Hi, currently I am running a Rails app on Heroku, and everything is working great with exception of generating PDF documents that sometimes contain thousands of records. Heroku has a built-in timeout of 30 seconds, so if the request takes more than 30 seconds, it's abandoned. That's fine, since they offer delayed_job support built-in. However, all of the PDF's i generate follow a typical restful pattern. For instance, a request to "/posts.pdf" generates a pdf (using PRAWN and PRAWNTO) and it's delivered to the browser. So my basic question is, how do I create dynamically generated PDF's with delayed_job while maintaining the basic RESTful patterns Rail's so conveniently provides. Thanks.

• jquery Ajax $.ajaxError

  - by cf_PhillipSenn

  I have a bunch of ajax calls that contain success and error conditions like this one: $.ajax({ url: 'Remote/State.cfc' ,type: "POST" ,data: { 'method': 'UpdateStateName' ,'StateID': StateID ,'StateName': StateName } ,success: function(result){ if (isNaN(result)) { $('#msg').text(result).addClass('err'); } else { $('#' + result + ' input[name="StateName"]').addClass('changed'); }; } ,error: function(msg){ $('#msg').text('Connection error').addClass('err'); } }); All the error conditions are the same. In other words, they all put the phrase "Connection error" in the msg id. Q1: Could I remove all these and replace them with $().ajaxError(function(myEvent, request, settings, thrownError) { $('#msg').text('Connection error').addClass('err'); }); Q2: How would you use myEvent and request to display a more informative error message?

• passing values to pages

  - by Indranil Mutsuddy

  Hello friends, What i am trying here is to pass values to other pages. When i include the following code private void Button1_Click(object sender, System.EventArgs e) { // Value sent using HttpResponse Response.Redirect("WebForm5.aspx?Name="+txtName.Text); } if (Request.QueryString["Name"]!= null) Response.write( Request.QueryString["Name"]); everything works fine the name gets displayed. Now if use MemberId instead, though i can see the Id in the Url, but while checking for Null in other page, its true. Whats wrong?? Now I tried the same thing using session i.e. Session["MemberId"] = this.TxtEnterMemberId.Text; if (MemberSex.Equals("M")) Response.Redirect("PatientDetailsMale.aspx",false ); Page_load event of the other page if (Session["MemberId"] != null) mid = Session["MemberId"].ToString(); IT Works..Could u guys explain the behaviour please? P.S. Can anyone give a breif in layman words about SessionId and its usage. Thanking you, Indranil

• Extract single element from XMLHttpRequest

  Hi! I am actually making a Sidebar Gadget, (which is AJAX-based) and I am looking for a way to extract a single element from an AJAX Request. The only way I found yet was to do something like that: var temp = document.createElement("div"); temp.innerHTML = HttpRequest.innerText; document.body.appendChild(temp); temp.innerHTML = document.getElementByID("WantedElement").innerText; But it is pretty ugly, I would like to extract WantedElement directly from the request without adding it to the actual document... Thank you!

• Opening response stream in silverlight

  - by John Maloney

  Hello, I am attempting to return a image from a server using Silverlight 3. The server returns the Response stream like this: context.Response.ContentType = imageFactory.ContentType imgStream.WriteTo(context.Response.OutputStream) imgStream.Close() context.Response.End() On the Silverlight client I am handling the stream like: Dim request As HttpWebRequest = result.AsyncState Dim response As HttpWebResponse = request.EndGetResponse(result) Dim responseStream As IO.Stream = response.GetResponseStream() I want to take that stream and open the browsers save dialog, one option I have explored is using the Html.Window.Navigate(New Uri("image url")) and this opened the correct browser default dialog but it is not an option because I need to send extended information(e.g. XML) to the server through the HttpRequest.Headers.Item and the Navigate doesn't allow this. How can I take a Response Stream and force the default browser Save dialog to appear from the Silverlight Application without using the Html.Window.Navigate(New Uri("image url"))?

When the user clicks an option in the select box, I make a request for the related data, returned in a JSON object, which gets put into the form elements. When the form is saved, the request goes thru and the listbox is rebuilt with the updated data. Since it's being rebuilt I'm trying to use delegation on the listbox's parent div for the onchange code. The trouble I'm having is with IE8 (big shock) not firing the delegated event. I have the following HTML: <div id="listwrapper" class="span-10 append-1 last"> <select id="list" name="list" size="20"> <option value="86">Adrian Franklin</option> <option value="16">Adrian McCorvey</option> <option value="196">Virginia Thomas</option> </select> </div> and the following script to go with it: window.addEvent('domready', function() { var jsonreq = new Request.JSON(); $('listwrapper').addEvent('change:relay(select)', function(e) { alert('this doesn't fire in IE8'); e.stop(); var status= $('statuswrapper').empty().addClass('ajax-loading'); jsonreq.options.url = 'de_getformdata.php'; jsonreq.options.method = 'post'; jsonreq.options.data = {'getlist':'<?php echo $getlist ?>','pkey':$('list').value}; jsonreq.onSuccess = function(rObj, rTxt) { status.removeClass('ajax-loading'); for (key in rObj) { status.set('html','You are currently editing '+rObj['cname']); if ($chk($(key))) $(key).value = rObj[key]; } $('lalsoaccomp-yes').set('checked',(($('naccompkey').value > 0)?'true':'false')); $('lalsoaccomp-no').set('checked',(($('naccompkey').value > 0)?'false':'true')); } jsonreq.send(); }); }); (I took out a bit of unrelated stuff). So this all works as expected in firefox, but IE8 refuses to fire the delegated change event on the select element. If I attach the change function directly to the select, then it works just fine. Am I missing something? Does IE8 just not like the :relay? Sidenote: I'm very new to mootools and javascripting, etc, so if there's something that can be improved code-wise, please let me know too.. Thanks!

• Configurator Scan not picking up views

  - by mxmissile

  New to Py and Python. I'm trying to get pyramid Configurator scan to find my views, but I seem to be missing something, it's not picking up my "view" index here are my files: app.py from wsgiref.simple_server import make_server from pyramid.config import Configurator if __name__ == '__main__': config = Configurator() config.add_route('home', '/') config.scan() app = config.make_wsgi_app() server = make_server('0.0.0.0', 6543, app) server.serve_forever() and index.py from pyramid.view import view_config from pyramid.response import Response @view_config(route_name='home') def index(request): print'Incoming request' return Response('<body><h1>Home</h1></body>') Its returning a 404. However, if I remove config.scan() and add the view manually it works fine. from wsgiref.simple_server import make_server from pyramid.config import Configurator from index import index if __name__ == '__main__': config = Configurator() config.add_route('home', '/') config.add_view(index, route_name='home')

• design question for transportation agency/workflow system

  - by George2

  Hello everyone, I am designing a transportation agency/workflow system, and it including 3 types of people, customer who requests to transport some stuff, drivers who deliver the stuff, and truck manager who manages transport source/destination truck coordination and communicates/organizes drivers. The system is expected to be a web site, and 3 kinds of people could use the web site to submit request, accept request, monitor status of specific stuff transportation, etc. The web site is more like an open agency or a workflow system. I am wondering whether there are any existing technologies, tools or projects (better to be open source, but not a must) which I could build my application faster based on? I prefer to use .Net technologies, but not a must. thanks in advance, George

• Using new Image().src for click tracking

  - by razass

  I am attempting to figure out why this click tracker isn't working. The code was written by another developer so I am not entirely sure if this ever did work. function trackSponsor(o, p) { (new Image()).src = PATH_BASE + 'click/' + p + '/' + o + "?_cache=" + (+(new Date())); return false; } From what I can gather is that when this function is called it 'creates a new image' to fire a php script asynchronously. According to Firebug, the request is made however it is 'aborted' ~30ms in. The odd thing is that it will 'sometimes' work as in 1 in every 10+ regardless of the browser. I would much rather fix this so that it works instead of re-writing it as an ajax request. Any help is appreciated. Thanks in advance.
