    paypal ipn case is not calling in paypal "pay now". In paypal button the following is set. return : "http://localhost/paypal.php?ch=return" cancel_return : "cancel_return" value="http://localhost/paypal.php?ch=cancel" notify_url : value="http://localhost/paypal.php?ch=ipn" paypal_form.php <form name="paypal" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post"> <input type="hidden" name="cmd" value="_xclick"> <input type="hidden" name="rm" value="2"> <input type="hidden" name="no_notes" value="1"> <input type="hidden" name="custom" value="1"> <input type="hidden" name="business" value="[email protected]"> <input type="hidden" name="return" id="return" value="http://localhost/paypal.php?ch=return"> <input type="hidden" name="cancel_return" id="cancel_return" value="http://localhost/paypal.php?ch=cancel"> <input type="hidden" name="notify_url" id="notify_url" value="http://localhost/paypal.php?ch=ipn"> <input type="image" src="https://www.sandbox.paypal.com/WEBSCR-640-20110429-1/en_GB/i/btn/btn_paynow_SM.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online."> <img alt="" border="0" src="https://www.sandbox.paypal.com/WEBSCR-640-20110429-1/en_GB/i/scr/pixel.gif" width="1" height="1"> paypal.php <? include('db_connect.php'); $choice=isset($_GET['ch'])?$_GET['ch']:''; switch($choice){ case 'return': print "Thank You For Buying this product,Please Visit Again,If is there any complements Then suggest us.."; break; case 'ipn': $sql="INSERT INTO paypal(add_date) VALUES(now())"; mysql_query($sql); $x = fopen('test1.txt','w+'); $str2 = 'post data:dfydfhgfhjg'; foreach($_POST as $k=>$v){ $str2 .= $k.'--'.$v; } fwrite($x,$str2); fclose($x); break; case 'cancel': print "Thank You for visiting this site,Please inform your friend to buy products through paypal which is easy service...

  • Suggestions for designing large-scale Java webapp from the group up

    - by Chris Thompson
    Hi all, I'm about to start developing a large-scale system and I'm struggling with which direction to proceed. I've done plenty of Java web apps before and I have plenty of experience with servlet containers and GWT and some experience with Spring. The problem is most of my webapps have been thrown together just to be a proof of concept and what I'm struggling with is what set of frameworks to use. I need to have both a browser based application as well as a web service designed to support access from mobile devices (Android and iPhone for now). Ideally, I'd like to design this system in such a way that I don't end up rewriting all of my servlets for each client (browser and phone) although I don't mind having some small checks in there to properly format the data. In addition, although I'm the only developer now, that won't necessarily be the case down the road and I'd like to design something that scales well both with regards to traffic and number of developers (isn't just a nightmare to maintain). So where I am now is planning on using GWT to design the browser-based interface but I'm struggling with how to reuse that code with to present the interface (most likely xml) for the mobile devices. Using GWT RPC would, I think, make it relatively easy to do all of the AJAX in the browser, but might make generating xml for the mobile phones difficult. In addition, I like the idea of using something like Hibernate for persistence and Spring Security to secure the whole thing. Again, I'm not sure how well those will cooperate with GWT (I think Hibernate should be fine...) There's obviously a lot more to this than I've presented here, but I've tried to give you the 5-minute overview. I'm a bit stumped and was wondering if anybody in the community had any experience starting from this place. Does what I'm trying to do make sense? Is it realistic? I have no doubt I can make all of these frameworks speak the same language, I'm just wondering if it's worth my time to fight with them. Also, am I missing a framework that would be really beneficial? Thanks in advance and sorry for the relatively broad question... Chris

  • Cannot parse persistence unit from class path resource

    - by Grzegorz S
    so I have this problem in running my Spring WS app which implements JPA ( or should implement..)

  • Using Hibernate to do a query involving two tables

    - by Nathan Spears
    I'm inexperienced with sql in general, so using Hibernate is like looking for an answer before I know exactly what the question is. Please feel free to correct any misunderstandings I have. I am on a project where I have to use Hibernate. Most of what I am doing is pretty basic and I could copy and modify. Now I would like to do something different and I'm not sure how configuration and syntax need to come together. Let's say I have two tables. Table A has two (relevant) columns, user GUID and manager GUID. Obviously managers can have more than one user under them, so queries on manager can return more than one row. Additionally, a manager can be managing the same user on multiple projects, so the same user can be returned multiple times for the same manager query. Table B has two columns, user GUID and user full name. One-to-one mapping there. I want to do a query on manager GUID from Table A, group them by unique User GUID (so the same User isn't in the results twice), then return those users' full names from Table B. I could do this in sql without too much trouble but I want to use Hibernate so I don't have to parse the sql results by hand. That's one of the points of using Hibernate, isn't it? Right now I have Hibernate mappings that map each column in Table A to a field (well the get/set methods I guess) in a DAO object that I wrote just to hold that Table's data. I could also use the Hibernate DAOs I have to access each table separately and do each of the things I mentioned above in separate steps, but that would be less efficient (I assume) that doing one query. I wrote a Service object to hold the data that gets returned from the query (my example is simplified - I'm going to keep some other data from Table A and get multiple columns from Table B) but I'm at a loss for how to write a DAO that can do the join, or use the DAOs I have to do the join. FYI, here is a sample of my hibernate config file (simplified to match my example): <hibernate-mapping package="com.my.dao"> <class name="TableA" table="table_a"> <id name="pkIndex" column="pk_index" /> <property name="userGuid" column="user_guid" /> <property name="managerGuid" column="manager_guid" /> </class> </hibernate-mapping> So then I have a DAOImplementation class that does queries and returns lists like public List<TableA> findByHQL(String hql, Map<String, String> params) etc. I'm not sure how "best practice" that is either.

  • Amusing or Sad? Network Solutions

    - by dbasnett
    When I got sick my email ended up in every drug sellers email list. Some days I get over 200 emails selling everything from Viagra to Xanax. Either they don't know what my condition is or they are telling me you are a goner, might as well chill-ax and have a good time. In order to cut down on the mail being downloaded I thought I would add all of the Junk email senders from Outlook to my Network Solution mail server. Much to my amazement I could not find that import Spammers button, so I submitted a tech support request. Here is the response: Thank you for contacting Network Solutions Customer Service Department. We are committed to creating the best Customer experience possible. One of the first ways we can demonstrate our commitment to this goal is to quickly and efficiently handle your recent request. We apologize for any inconvenience this might have caused you. With regard to your concern, please be advised that we cannot import blocked senders in to you e-mail servers. An alternative option is for you to create a Custom Filter that filters unwanted e-mails. To create a Custom Filter: Open a Web browser (e.g., Netscape, Microsoft Internet Explorer, etc.). Type mail.[domain name].[ext] in the address line. Login to your Network Solutions email account. Click on the Configuration left menu tab. Click on the Custom Filter link. Type the rule name. blah, blah, blah Basically add them one at a time. "We are committed to creating the best Customer experience possible." No you are not. You are trying to squeeze every nickle you can out of me. "With regard to your concern, please be advised that we cannot import blocked senders in to you e-mail servers." Maybe I should apply for a job to write those ten complicated lines of code... Maybe I should question my choice of vendors, because if they truly "cannot" then they are to stupid to have my business. It is both amusing and sad. I'll be posting this in every forum I am a member of.

  • What is a good dumbed-down, safe template system for PHP?

    - by Wilhelm
    (Summary: My users need to be able to edit the structure of their dynamically generated web pages without being able to do any damage.) Greetings, ladies and gentlemen. I am currently working on a service where customers from a specific demographic can create a specific type of web site and fill it with their own content. The system is written in PHP. Many of the users of this system wish to edit how their particular web site looks, or, more commonly, have a designer do it for them. Editing the CSS is fine and dandy, but sometimes that's not enough. Sometimes they want to shuffle the entire page structure around by editing the raw HTML of the dynamically created web pages. The templating system used by WordPress is, as far as I can see, perfect for my use. Except for one thing which is critically important. In addition to being able to edit how comments are displayed or where the menu goes, someone editing a template can have that template execute arbitrary PHP code. As the same codebase runs all these different sites, with all content in the same databse, allowing my users to run arbitrary code is clearly out of the question. So what I need, is a dumbed-down, idiot-proof templating system where my users can edit most of the page structure on their own, pulling in the dynamic sections wherever, without being able to even echo 1+1;. Observe the following psuedocode: <!DOCTYPE html> <title><!-- $title --></title> <!-- header() --> <!-- menu() --> <div>Some random custom crap added by the user.</div> <!-- page_content() --> That's the degree of power I'd like to grant my users. They don't need to do their own loops or calculations or anything. Just include my variables and functions and leave the rest to me. I'm sure I'm not the only person on the planet that needs something like this. Do you know of any ready-made templating systems I could use? Thanks in advance for your reply.

  • Can I retain a Google apps session token permanently for a specific user who logs into my google app

    - by Ali
    Hi guys, is it possible to retain upon authorization a single session token for a user who signs into my gogle application. CUrrently my application seems to every now and then require the user to authenticate into google apps. I think it has to do with session dying out or so. I have the following code: function getCurrentUrl() { global $_SERVER; $php_request_uri = htmlentities(substr($_SERVER['REQUEST_URI'], 0, strcspn($_SERVER['REQUEST_URI'], "\n\r")), ENT_QUOTES); if (isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) == 'on') { $protocol = 'https://'; } else { $protocol = 'http://'; } $host = $_SERVER['HTTP_HOST']; if ($_SERVER['SERVER_PORT'] != '' && (($protocol == 'http://' && $_SERVER['SERVER_PORT'] != '80') || ($protocol == 'https://' && $_SERVER['SERVER_PORT'] != '443'))) { $port = ':' . $_SERVER['SERVER_PORT']; } else { $port = ''; } return $protocol . $host . $port . $php_request_uri; } function getAuthSubUrl($n=false) { $next = $n?$n:getCurrentUrl(); $scope = 'http://docs.google.com/feeds/documents https://www.google.com/calendar/feeds/ https://spreadsheets.google.com/feeds/ https://www.google.com/m8/feeds/ https://mail.google.com/mail/feed/atom/'; $secure = false; $session = true; //echo Zend_Gdata_AuthSub::getAuthSubTokenUri($next, $scope, $secure, $session);; return Zend_Gdata_AuthSub::getAuthSubTokenUri($next, $scope, $secure, $session).(isset($_SESSION['domain'])?'&hd='.$_SESSION['domain']:''); } function _regenerate_token() { global $BASE_URL; if(!$_SESSION['token']) { if(isset($_GET['token'])): $_SESSION['token'] = Zend_Gdata_AuthSub::getAuthSubSessionToken($_GET['token']); return; else: _regenerate_sessions(); _redirect(getAuthSubUrl($BASE_URL . '/index.php?'.$_SERVER['QUERY_STRING'])); endif; } } _regenerate_token(); I know I'm doing it all wrong here and I don't know why :( I have a CONSUMER SECRET code but only use it whereever I need to access a google service. However something is wrong with my authentication as the user has to periodically 'grant access to my application' and reauthorise himself... help please

  • jQuery .ajax call to bit.ly returns results in IE but not FF or Chrome

    - by Ian Quigley
    I am trying to call to the bit.ly URL shortening service using jQuery with an .ajax call. <html><head> <script type="text/javascript" src="http://www.twipler.com/settings/scripts/jquery.1.4.min.js"></script> <script type="text/javascript"> jQuery.fn.shorten = function(url) { var resultUrl = url; $.ajax( { url: "http://api.bit.ly/shorten?version=2.0.1&login=twipler&apiKey=R_4e618e42fadbb802cf95c6c2dbab3763&longUrl=" + url, async: false, dataType: 'json', data: "", type: "GET", success: function (json) { resultUrl = json.results[url].shortUrl; } }); return resultUrl; } ; </script></head><body> <a href="#" onclick="alert($().shorten('http://amiconnectedtotheinternet.com'));"> Shorten</a> </body> </html> This works in IE8 but does not work in FireFox (3.5.9) nor in Chrome. In both cases 'json' is null. Headers in IE8 GET http://api.bit.ly/shorten?ver..[SNIP]..dtotheinternet.com HTTP/1.1 Accept: application/json, text/javascript, */* Accept-Language: en-US Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; Media Center PC 6.0; InfoPath.2; .NET CLR 1.1.4322; .NET CLR 3.5.30729; .NET CLR 3.0.30729) Host: api.bit.ly Connection: Keep-Alive Headers in Chrome GET http://api.bit.ly/shorten?versio..[SNIP]..nectedtotheinternet.com HTTP/1.1 Host: api.bit.ly Connection: keep-alive User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1045 Safari/532.5 Origin: file:// Accept: application/json, text/javascript, */* Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 So the only obvious difference is that Chrome is sending "Origin: file://" and I've no idea how to stop it doing that.

  • Android HttpsURLConnection and JSON for new GCM

    - by Ryan Gray
    I'm overhauling certain parts of my app to use the new GCM service to replace C2DM. I simply want to create the JSON request from a Java program for testing and then read the response. As of right now I can't find ANY formatting issues with my JSON request and the google server always return code 400, which indicates a problem with my JSON. http://developer.android.com/guide/google/gcm/gcm.html#server JSONObject obj = new JSONObject(); obj.put("collapse_key", "collapse key"); JSONObject data = new JSONObject(); data.put("info1", "info_1"); data.put("info2", "info 2"); data.put("info3", "info_3"); obj.put("data", data); JSONArray ids = new JSONArray(); ids.add(REG_ID); obj.put("registration_ids", ids); System.out.println(obj.toJSONString()); I print my request to the eclipse console to check it's formatting byte[] postData = obj.toJSONString().getBytes(); try{ URL url = new URL("https://android.googleapis.com/gcm/send"); HttpsURLConnection.setDefaultHostnameVerifier(new JServerHostnameVerifier()); HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); conn.setDoOutput(true); conn.setDoInput(true); conn.setUseCaches(false); conn.setRequestMethod("POST"); conn.setRequestProperty("Content-Type", "application/json"); conn.setRequestProperty("Authorization", "key=" + API_KEY); System.out.println(conn.toString()); OutputStream out = conn.getOutputStream(); // exception thrown right here. no InputStream to get InputStream in = conn.getInputStream(); byte[] response = null; out.write(postData); out.close(); in.read(response); JSONParser parser = new JSONParser(); String temp = new String(response); JSONObject temp1 = (JSONObject) parser.parse(temp); System.out.println(temp1.toJSONString()); int responseCode = conn.getResponseCode(); System.out.println(responseCode + ""); } catch(Exception e){ System.out.println("Exception thrown\n"+ e.getMessage()); } } I'm sure my API key is correct as that would result in error 401, so says the google documentation. This is my first time doing JSON but it's easy to understand because of its simplicity. Anyone have any ideas on why I always receive code 400? update: I've tested the google server example classes provided with gcm so the problem MUST be with my code.

  • Salesforce consuming XML and display data in Visualforce report

    - by JavaKungFu
    Firstly, this question requires a bit of introduction so please bear with me. The high level is that I am connecting to a outside web service which will return some XML to my apex controller. The idea is that I want to display the XML returned into a nice tabular format in a VisualForce page. The format of the XML coming back will look something like this: <Wrapper><reportTable name='table_id' title='Report Title'> <row> <Element1><![CDATA[campaign_id]]></Element1> <Element2><![CDATA[577373]]></Element2> <Element3><![CDATA[4129]]></Element3> <Element4 dataFormat='2' dataSuffix='%'><![CDATA[0.7151]]></Element4> <Element5><![CDATA[2010-04-04]]></Element5> <Element6><![CDATA[2010-05-03]]></Element6> </row> </reportTable> ... Now currently I am using the XMLdom utility class (developed by SF for XML functions) to map this data into a custom object "reportTable" which contains a list of "row" custom objects. The reason I am building it out this way is because I don't know how many elements will be in each row, nor the number of rows. The Visualforce page looks something like this: <table><apex:repeat value="{!reportTables}" var="table"> <apex:repeat value="{!table.rows}" var="row"> <tr> <apex:repeat value="{!row.ColumnValue}" var="column"> <apex:repeat value="{!column}" var="value"> <td> <apex:outputText value="{!value}" /> </td> </apex:repeat> </apex:repeat> </tr> </apex:repeat> Questions are: 1) Does this seem like a good approach to the problem? 2) Is there a simpler/better way to consume the XML besides writing my own custom objects to map VF to? Open to any and all suggestions. I really hope there is a better way than building the HTML table myself, as then I also have to deal with styling and alignment etc. Thanks.

    Hello, I have a problem searching through amazon web servise using PHP in my CodeIgniter. I get InvalidParameter timestamp is not in ISO-8601 format response from the server.

  • mysql index optimization for a table with multiple indexes that index some of the same columns

    - by Sean
    I have a table that stores some basic data about visitor sessions on third party web sites. This is its structure: id, site_id, unixtime, unixtime_last, ip_address, uid There are four indexes: id, site_id/unixtime, site_id/ip_address, and site_id/uid There are many different types of ways that we query this table, and all of them are specific to the site_id. The index with unixtime is used to display the list of visitors for a given date or time range. The other two are used to find all visits from an IP address or a "uid" (a unique cookie value created for each visitor), as well as determining if this is a new visitor or a returning visitor. Obviously storing site_id inside 3 indexes is inefficient for both write speed and storage, but I see no way around it, since I need to be able to quickly query this data for a given specific site_id. Any ideas on making this more efficient? I don't really understand B-trees besides some very basic stuff, but it's more efficient to have the left-most column of an index be the one with the least variance - correct? Because I considered having the site_id being the second column of the index for both ip_address and uid but I think that would make the index less efficient since the IP and UID are going to vary more than the site ID will, because we only have about 8000 unique sites per database server, but millions of unique visitors across all ~8000 sites on a daily basis. I've also considered removing site_id from the IP and UID indexes completely, since the chances of the same visitor going to multiple sites that share the same database server are quite small, but in cases where this does happen, I fear it could be quite slow to determine if this is a new visitor to this site_id or not. The query would be something like: select id from sessions where uid = 'value' and site_id = 123 limit 1 ... so if this visitor had visited this site before, it would only need to find one row with this site_id before it stopped. This wouldn't be super fast necessarily, but acceptably fast. But say we have a site that gets 500,000 visitors a day, and a particular visitor loves this site and goes there 10 times a day. Now they happen to hit another site on the same database server for the first time. The above query could take quite a long time to search through all of the potentially thousands of rows for this UID, scattered all over the disk, since it wouldn't be finding one for this site ID. Any insight on making this as efficient as possible would be appreciated :) Update - this is a MyISAM table with MySQL 5.0. My concerns are both with performance as well as storage space. This table is both read and write heavy. If I had to choose between performance and storage, my biggest concern is performance - but both are important. We use memcached heavily in all areas of our service, but that's not an excuse to not care about the database design. I want the database to be as efficient as possible.

  • ASP.NET Client to Server communication

    - by Nelson
    Can you help me make sense of all the different ways to communicate from browser to client in ASP.NET? I have made this a community wiki so feel free to edit my post to improve it. Specifically, I'm trying to understand in which scenario to use each one by listing how each works. I'm a little fuzzy on UpdatePanel vs CallBack (with ViewState): I know UpdatePanel always returns HTML while CallBack can return JSON. Any other major differences? ...and CallBack (without ViewState) vs WebMethod. CallBack goes through most of the Page lifecycle, WebMethod doesn't. Any other major differences? IHttpHandler Custom handler for anything (page, image, etc.) Only does what you tell it to do (light server processing) Page is an implementation of IHttpHandler If you don't need what Page provides, create a custom IHttpHandler If you are using Page but overriding Render() and not generating HTML, you probably can do it with a custom IHttpHandler (e.g. writing binary data such as images) By default can use the .axd or .ashx file extensions -- both are functionally similar .ashx doesn't have any built-in endpoints, so it's preferred by convention Regular PostBack (System.Web.UI.Page : IHttpHandler) Inherits Page Full PostBack, including ViewState and HTML control values (heavy traffic) Full Page lifecycle (heavy server processing) No JavaScript required Webpage flickers/scrolls since everything is reloaded in browser Returns full page HTML (heavy traffic) UpdatePanel (Control) Control inside Page Full PostBack, including ViewState and HTML control values (heavy traffic) Full Page lifecycle (heavy server processing) Controls outside the UpdatePanel do Render(NullTextWriter) Must use ScriptManager If no client-side JavaScript, it can fall back to regular PostBack with no JavaScript (?) No flicker/scroll since it's an async call, unless it falls back to regular postback. Can be used with master pages and user controls Has built-in support for progress bar Returns HTML for controls inside UpdatePanel (medium traffic) Client CallBack (Page, System.Web.UI.ICallbackEventHandler) Inherits Page Most of Page lifecycle (heavy server processing) Takes only data you specify (light traffic) and optionally ViewState (?) (medium traffic) Client must support JavaScript and use ScriptManager No flicker/scroll since it's an async call Can be used with master pages and user controls Returns only data you specify in format you specify (e.g. JSON, XML...) (?) (light traffic) WebMethod Class implements System.Web.Service.WebService HttpContext available through this.Context Takes only data you specify (light traffic) Server only runs the called method (light server processing) Client must support JavaScript No flicker/scroll since it's an async call Can be used with master pages and user controls Returns only data you specify, typically JSON (light traffic) Can create instance of server control to render HTML and sent back as string, but events, paging in GridView, etc. won't work PageMethods Essentially a WebMethod contained in the Page class, so most of WebMethod's bullet's apply Method must be public static, therefore no Page instance accessible HttpContext available through HttpContext.Current Accessed directly by URL Page.aspx/MethodName (e.g. with XMLHttpRequest directly or with library such as jQuery) Setting ScriptManager property EnablePageMethods="True" generates a JavaScript proxy for each WebMethod Cannot be used directly in user controls with master pages and user controls Any others?

  • Tools to help with analysing log files

    I am developing a C# .NET application.

  • .NET Impersonate and file upload issues

    - by Jagd
    I have a webpage that allows a user to upload a file to a network share. When I run the webpage locally (within VS 2008) and try to upload the file, it works! However, when I deploy the website to the webserver and try to upload the file through the webpage, it doesn't work! The error being returned to me on the webserver says "Access to the path '\05prd1\emp\test.txt' is denied. So, obviously, this is a permissions issue. The network share is configured to allow full access both to me (NT authentication) and to the NETWORK SERVICE (which is .NET's default account and what we have set in our IIS application pool as the default user for this website). I have tried this with and without impersonation upon the webserver and neither way works, yet both ways work on my local machine (in other words, with and without impersonation works on my local machine). The code that does the file upload is below. Please note that the code below includes impersonation, but like I said above, I've tried it with and without impersonation and it's made no difference. if (fuCourses.PostedFile != null && fuCourses.PostedFile.ContentLength > 0) { System.Security.Principal.WindowsImpersonationContext impCtx; impCtx = ((System.Security.Principal.WindowsIdentity)User.Identity).Impersonate(); try { lblMsg.Visible = true; // The courses file to be uploaded HttpPostedFile file = fuCourses.PostedFile; string fName = file.FileName; string uploadPath = "\\\\05prd1\\emp\\"; // Get the file name if (fName.Contains("\\")) { fName = fName.Substring( fName.LastIndexOf("\\") + 1); } // Delete the courses file if it is already on \\05prd1\emp FileInfo fi = new FileInfo(uploadPath + fName); if (fi != null && fi.Exists) { fi.Delete(); } // Open new file stream on \\05prd1\emp and read bytes into it from file upload FileStream fs = File.Create(uploadPath + fName, file.ContentLength); using (Stream stream = file.InputStream) { byte[] b = new byte[4096]; int read; while ((read = stream.Read(b, 0, b.Length)) > 0) { fs.Write(b, 0, read); } } fs.Close(); lblMsg.Text = "File Successfully Uploaded"; lblMsg.ForeColor = System.Drawing.Color.Green; } catch (Exception ex) { lblMsg.Text = ex.Message; lblMsg.ForeColor = System.Drawing.Color.Red; } finally { impCtx.Undo(); } } Any help on this would be very appreciated!

  • Connected host failed to respond (internal NAT address)

    - by MostRandom
    I'm writing my first C# web application that connects to an XML based service. It requires that I present a certificate and feed the XML stream. It seems to authenticate properly but then it gives the following error: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.1.10.4:3128 The funny thing is that I'm not on a proxy or anything like that. I'm connecting directly to the internet. At one point I we did use a proxy that with internal NAT address. So my question is: Does Visual Studio have some sort of default proxy setting that I need to change? This IP is no longer used for anything, so I know that I don't need to use any proxy authentication code. using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Net; using System.Security.Cryptography.X509Certificates; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; namespace WebApplication1 { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Uri requestURI = new Uri("*site omitted*"); //Create the Request Object HttpWebRequest pageRequest = (HttpWebRequest)WebRequest.Create(requestURI); //After installing the cert on the server export a client cert to the working directory as Deluxe.cer string certFile = "*certificate omitted*"; X509Certificate cert = X509Certificate.CreateFromCertFile(certFile); //Pull in your Data, if it is from an external xml as below or create an xml string with variables if a dynamic post is required. string xmlPath = "*XML omitted*"; System.Xml.XmlDocument passXML = new System.Xml.XmlDocument(); passXML.Load(xmlPath); //XML String with the data needed to pass string postData = passXML.OuterXml; //Set the Request Object parameters pageRequest.ContentType = "application/x-www-form-urlencoded"; pageRequest.Method = "POST"; pageRequest.AllowWriteStreamBuffering = false; pageRequest.AllowAutoRedirect = false; pageRequest.ClientCertificates.Add(cert); postData = "xml_data=" + Server.UrlEncode(postData); pageRequest.ContentLength = postData.Length; //Create the Post Stream Object System.IO.StreamWriter postStream = new System.IO.StreamWriter(pageRequest.GetRequestStream()); //Write the data to the post stream postStream.Write(postData); postStream.Flush(); postStream.Close(); //Set the Response Object HttpWebResponse postResponse = (HttpWebResponse)pageRequest.GetResponse();

  • Is it possible to use XStream with an abstract node?

    - by Dan Watling
    My client application is making calls to a service that returns a common "root" XML, but a different result node. The "root" XML contains possible error codes. Is it possible to use XStream in this scenario? Example: public class RootNode { ErrorInfo errorInfo; BaseResult result; ... } public class ErrorInfo { String message; ... } public abstract BaseResult { } public class SearchResult extends BaseResult { List<Object> searchResults; ... } public class AccountResult extends BaseResult { String name; ... } The XML coming back could be one of two formats: <root> <errorInfo><message>...</message></errorInfo> <result> <searchResults>...</searchResults> </result> </root> OR <root> <errorInfo><message>...</message></errorInfo> <result> <name>...</name> </result> </root> I have set up my XStream object as follows: XStream x = new XStream(); x.alias("root", Root.class); x.alias("errorInfo", ErrorInfo.class); x.alias("result", <SearchResult.class OR AccountResult.class depending on what I am expecting back>); Of course, when I run this I receive an error telling me XStream cannot instantiate the base class (BaseResult). For fun, I also converted the BaseResult into an interface but received a similar error. I've looked through XStream's documentation and it isn't clear to me how to handle a situation like the one I just described. Is it even possible to do using XStream? Thanks, -Dan

  • Asynchronous vs Synchronous vs Threading in an iPhone App

    - by Coocoo4Cocoa
    I'm in the design stage for an app which will utilize a REST web service and sort of have a dilemma in as far as using asynchronous vs synchronous vs threading. Here's the scenario. Say you have three options to drill down into, each one having its own REST-based resource. I can either lazily load each one with a synchronous request, but that'll block the UI and prevent the user from hitting a back navigation button while data is retrieved. This case applies almost anywhere except for when your application requires a login screen. I can't see any reason to use synchronous HTTP requests vs asynchronous because of that reason alone. The only time it makes sense is to have a worker thread make your synchronous request, and notify the main thread when the request is done. This will prevent the block. The question then is bench marking your code and seeing which has more overhead, a threaded synchronous request or an asynchronous request. The problem with asynchronous requests is you need to either setup a smart notification or delegate system as you can have multiple requests for multiple resources happening at any given time. The other problem with them is if I have a class, say a singleton which is handling all of my data, I can't use asynchronous requests in a getter method. Meaning the following won't go: - (NSArray *)users { if(users == nil) users = do_async_request // NO GOOD return users; } whereas the following: - (NSArray *)users { if(users == nil) users == do_sync_request // OK. return users; } You also might have priority. What I mean by priority is if you look at Apple's Mail application on the iPhone, you'll notice they first suck down your entire POP/IMAP tree before making a second request to retrieve the first 2 lines (the default) of your message. I suppose my question to you experts is this. When are you using asynchronous, synchronous, threads -- and when are you using either async/sync in a thread? What kind of delegation system do you have setup to know what to do when a async request completes? Are you prioritizing your async requests? There's a gamut of solutions to this all too common problem. It's simple to hack something out. The problem is, I don't want to hack and I want to have something that's simple and easy to maintain.

  • How to set up a wcf-structure over internet, and not on the localhost

    - by djerry
    Hey guys, I want to convert the wcf-structure i have from localhost to a service which runs over the internet. My server starts when replacing the localhost with my ip-address. But then my clients cannot connect to the server anymore. This is my server setup : static void Main(string[] args) { NetTcpBinding binding = new NetTcpBinding(SecurityMode.Message); Uri address = new Uri("net.tcp://192.168.10.26"); //_svc = new ServiceHost(typeof(MonitoringSystemService), address); _monSysService = new MonitoringSystemService(); _svc = new ServiceHost(_monSysService, address); publishMetaData(_svc, "http://192.168.10.26"); _svc.AddServiceEndpoint(typeof(IMonitoringSystemService), binding, "Monitoring Server"); _svc.Open(); } My app.config for the client looks like this : <configuration> <system.diagnostics> <sources> <source name="System.ServiceModel" switchValue="Information, ActivityTracing" propagateActivity="true"> <listeners> <add name="traceListener" type="System.Diagnostics.XmlWriterTraceListener" initializeData= "c:\log\Traces.svclog" /> </listeners> </source> </sources> </system.diagnostics> <system.serviceModel> <bindings> <netTcpBinding> <binding name="NetTcpBinding_IMonitoringSystemService" closeTimeout="00:00:10" openTimeout="00:00:10" receiveTimeout="00:10:00" sendTimeout="00:00:10" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxConnections="500" maxReceivedMessageSize="2147483647"> <readerQuotas maxDepth="32" maxStringContentLength="100000" maxArrayLength="100000" maxBytesPerRead="100000" maxNameTableCharCount="100000" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Message"> <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign"> <extendedProtectionPolicy policyEnforcement="Never" /> </transport> <message clientCredentialType="Windows" /> </security> </binding> </netTcpBinding> </bindings> <client> <endpoint address="net.tcp://192.168.10.26/Monitoring%20Server" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IMonitoringSystemService" contract="IMonitoringSystemService" > <!--name="NetTcpBinding_IMonitoringSystemService"--> <identity> <userPrincipalName value="DJERRYY\djerry" /> </identity> </endpoint> </client> </system.serviceModel> </configuration>

  • How can I call VC# webservice methods without ArgumentException?

    - by Zarius
    Currently, I'm trying to write a small tray application that will show the status and provide control of a server-side application exposed over webservice. The webservice only has 3 operations: start, stop and status. When I call any of these operations in code, they throw an ArgumentException citing "An item with the same key has already been added". I am compiling the webservice on Visual C# Express 2008, and .NET 3.5. The Code: private TelnetConnClient Conn { get { return new TelnetConnClient(); } } private bool Connected //call webservice operations { get { return Conn.Status(); } set { if(value) Conn.Start(); else Conn.Stop(); } } The Stacktrace: A first chance exception of type 'System.ArgumentException' occurred in mscorlib.dll at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource) at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add) at System.ServiceModel.TransactionFlowAttribute.ApplyBehavior(OperationDescription description, BindingParameterCollection parameters) at System.ServiceModel.TransactionFlowAttribute.System.ServiceModel.Description.IOperationBehavior.AddBindingParameters(OperationDescription description, BindingParameterCollection parameters) at System.ServiceModel.Description.DispatcherBuilder.AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection parameters) at System.ServiceModel.Description.DispatcherBuilder.BuildProxyBehavior(ServiceEndpoint serviceEndpoint, BindingParameterCollection& parameters) at System.ServiceModel.Channels.ServiceChannelFactory.BuildChannelFactory(ServiceEndpoint serviceEndpoint) at System.ServiceModel.ChannelFactory.CreateFactory() at System.ServiceModel.ChannelFactory.OnOpening() at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.ChannelFactory.EnsureOpened() at System.ServiceModel.ChannelFactory`1.CreateChannel(EndpointAddress address, Uri via) at System.ServiceModel.ChannelFactory`1.CreateChannel() at System.ServiceModel.ClientBase`1.CreateChannel() at System.ServiceModel.ClientBase`1.CreateChannelInternal() at System.ServiceModel.ClientBase`1.get_Channel() at KordiaConnect.ferries.TelnetConnClient.Start() in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Service References\ferries\Reference.cs:line 86 at coldshark.ferries.Main.set_Connected(Boolean value) in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Main.cs:line 22 at coldshark.ferries.Main.<.ctor>b__0(Object sender, EventArgs e) in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Main.cs:line 43 at System.Windows.Forms.NotifyIcon.OnClick(EventArgs e) at System.Windows.Forms.NotifyIcon.WmMouseUp(Message& m, MouseButtons button) at System.Windows.Forms.NotifyIcon.WndProc(Message& msg) at System.Windows.Forms.NotifyIcon.NotifyIconNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.PeekMessage(MSG& msg, HandleRef hwnd, Int32 msgMin, Int32 msgMax, Int32 remove) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run() at coldshark.ferries.Main..ctor() in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Main.cs:line 55 I can just call the webservice from the web interface, but this application will give me a handy status notification icon, and I'd really love to know why the out-of-the-box auto-generated code fails for no particular reason.

  • .NET C# Filestream writing to file and reading the bfile

    - by pythonrg7
    I have a web service that checks a dictionary to see if a file exists and then if it does exist it reads the file, otherwise it saves to the file. This is from a web app. I wonder what is the best way to do this because I occasionally get a FileNotFoundException exception if the same file is accessed at the same time. Here's the relevant parts of the code: String signature; signature = "FILE," + value1 + "," + value2 + "," + value3 + "," + value4; // this is going to be the filename string result; MultipleRecordset mrSummary = new MultipleRecordset(); // MultipleRecordset is an object that retrieves data from a sql server database if (mrSummary.existsFile(signature)) { result = mrSummary.retrieveFile(signature); } else { result = mrSummary.getMultipleRecordsets(System.Configuration.ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString.ToString(), value1, value2, value3, value4); mrSummary.saveFile(signature, result); } Here's the code to see if the file already exists: private static Dictionary dict = new Dictionary(); public bool existsFile(string signature) { if (dict.ContainsKey(signature)) { return true; } else { return false; } } Here's what I use to retrieve if it already exists: try { byte[] buffer; FileStream fileStream = new FileStream(@System.Configuration.ConfigurationManager.AppSettings["CACHEPATH"] + filename, FileMode.Open, FileAccess.Read, FileShare.Read); try { int length = 0x8000; // get file length buffer = new byte[length]; // create buffer int count; // actual number of bytes read JSONstring = ""; while ((count = fileStream.Read(buffer, 0, length)) > 0) { JSONstring += System.Text.ASCIIEncoding.ASCII.GetString(buffer, 0, count); } } finally { fileStream.Close(); } } catch (Exception e) { JSONstring = "{\"error\":\"" + e.ToString() + "\"}"; } If the file doesn't previously exist it saves the JSON to the file: try { if (dict.ContainsKey(filename) == false) { dict.Add(filename, true); } else { this.retrieveFile(filename, ipaddress); } } catch { } try { TextWriter tw = new StreamWriter(@System.Configuration.ConfigurationManager.AppSettings["CACHEPATH"] + filename); tw.WriteLine(JSONstring); tw.Close(); } catch { } Here are the details to the exception I sometimes get from running the above code: System.IO.FileNotFoundException: Could not find file 'E:\inetpub\wwwroot\cache\FILE,36,36.25,14.5,14.75'. File name: 'E:\inetpub\wwwroot\cache\FILE,36,36.25,14.5,14.75' at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share) at com.myname.business.MultipleRecordset.retrieveFile(String filename, String ipaddress)

  • What is the relationship between WebProxy & IWebProxy with respect to WebClient?

    - by Streamline
    I am creating an app (.NET 2.0) that uses WebClient to connect (downloaddata, etc) to/from a http web service. I am adding a form now to handle allowing proxy information to either be stored or set to use the defaults. I am a little confused about some things. First, some of the methods & properties available in either WebProxy or IWebProxy are not in both. What is the difference here with respect to setting up how WebClient will be have when it is called? Secondly, do I have to tell WebClient to use the proxy information if I set it using either WebProxy or IWebProxy class elsewhere? Or is it automatically inherited? Thirdly, when giving the option for the user to use the default proxy (whatever is set in IE) and using the default credentials (I assume also whatever is set in IE) are these two mutually exclusive? Or you only use default credentials when you have also used default proxy? This gets me to the whole difference between WebProxy and IWebProxy. WebRequest.DefaultProxy is a IWebPRoxy class but UseDefaultCredentials is not a method on the IWebProxy class, rather it is only on WebProxy and in turn, How to set the proxy to the WebRequest.DefautlProxy if they are two different classes? Here is my current method to read the stored form settings by the user - but I am not sure if this is correct, not enough, overkill, or just wrong because of the mix of WebProxy and IWebProxy: private WebProxy _proxyInfo = new WebProxy(); private WebProxy SetProxyInfo() { if (UseProxy) { if (UseIEProxy) { // is doing this enough to set this as default for WebClient? IWebProxy iProxy = WebRequest.DefaultWebProxy; if (UseIEProxyCredentials) { _proxyInfo.UseDefaultCredentials = true; } else { // is doing this enough to set this as default credentials for WebClient? WebRequest.DefaultWebProxy.Credentials = new NetworkCredential(ProxyUsername, ProxyPassword); } } else { // is doing this enough to set this as default for WebClient? WebRequest.DefaultWebProxy = new WebProxy(ProxyAddress, ParseLib.StringToInt(ProxyPort)); if (UseIEProxyCredentials) { _proxyInfo.UseDefaultCredentials = true; } else { WebRequest.DefaultWebProxy.Credentials = new NetworkCredential(ProxyUsername, ProxyPassword); } } } // Do I need to WebClient to absorb this returned proxy info if I didn't set or use defaults? return _proxyInfo; } Is there any reason to not just scrap storing app specific proxy information and only allow the app the ability to use the default proxy information & credentials for the logged in user? Will this ever not be enough if using HTTP? Part 2 Question: How can I test that the WebClient instance is using the proxy information or not?

  • Logging raw HTTP request/response in ASP.NET MVC & IIS7

    - by Greg Beech
    I'm writing a web service (using ASP.NET MVC) and for support purposes we'd like to be able to log the requests and response in as close as possible to the raw, on-the-wire format (i.e including HTTP method, path, all headers, and the body) into a database. What I'm not sure of is how to get hold of this data in the least 'mangled' way. I can re-constitute what I believe the request looks like by inspecting all the properties of the HttpRequest object and building a string from them (and similarly for the response) but I'd really like to get hold of the actual request/response data that's sent on the wire. I'm happy to use any interception mechanism such as filters, modules, etc. and the solution can be specific to IIS7. However, I'd prefer to keep it in managed code only. Any recommendations? Edit: I note that HttpRequest has a SaveAs method which can save the request to disk but this reconstructs the request from the internal state using a load of internal helper methods that cannot be accessed publicly (quite why this doesn't allow saving to a user-provided stream I don't know). So it's starting to look like I'll have to do my best to reconstruct the request/response text from the objects... groan. Edit 2: Please note that I said the whole request including method, path, headers etc. The current responses only look at the body streams which does not include this information. Edit 3: Does nobody read questions around here? Five answers so far and yet not one even hints at a way to get the whole raw on-the-wire request. Yes, I know I can capture the output streams and the headers and the URL and all that stuff from the request object. I already said that in the question, see: I can re-constitute what I believe the request looks like by inspecting all the properties of the HttpRequest object and building a string from them (and similarly for the response) but I'd really like to get hold of the actual request/response data that's sent on the wire. If you know the complete raw data (including headers, url, http method, etc.) simply cannot be retrieved then that would be useful to know. Similarly if you know how to get it all in the raw format (yes, I still mean including headers, url, http method, etc.) without having to reconstruct it, which is what I asked, then that would be very useful. But telling me that I can reconstruct it from the HttpRequest/HttpResponse objects is not useful. I know that. I already said it. Please note: Before anybody starts saying this is a bad idea, or will limit scalability, etc., we'll also be implementing throttling, sequential delivery, and anti-replay mechanisms in a distributed environment, so database logging is required anyway. I'm not looking for a discussion of whether this is a good idea, I'm looking for how it can be done.
