  • Space a valid delimiter for email addresses in email header?

    - by semanticalo
    Is it syntactically correct to delimit multiple email recipients in the "To" header of an email with spaces only or do I need to use another delimiter (a semicolon or the like)? Example (MIME data reads as follows): Date: Mon, 04 Oct 2010 06:14:16 +0200 From: [email protected] To: [email protected] [email protected] [email protected] Subject: Test Subject The above will be processed by many email processing applications, but I need to know whether it's correct according to standard (RFC). Unfortunately I didn't find anything useful on the internet so far. Thanks a million for your help!

  • Putting codes in email subjects

    - by Christian W
    We send out large quantities of email to our customers (work environment surveys). Sometimes our mailinglist for a client isn't quite up to date and we get bounce mails (address not found and such). However, since these all bounce back to the same address it's difficult to keep track on which bounce belongs to which client. (The email subject is usually pretty generic, like "Welcome to the work environment survey") This is why I would like to insert a identifier in the subject line of the email. So the subject would be "Welcome to the work environment survey (1234)" where 1234 is a number identifying the client/survey. We already rank pretty high because of the way our mailer handles sending the mails. Usually we contact the clients it-dept to get them to whitelist us in their firewall/spamfilter. Would this increase our spamscore in spamfilters?

  • How can I send an email from Mail.app to Outlook with an attachment that does not embed into the email body?

    - by JAG2007
    I'm using Mail.app (on Mac OS X 10.6) and when I send an email to users on PC Outlook, with an attached image, they get the email as an image embedded into the body, not as an attachement. I even tried clicking "view as icon" before sending the attachment from Macmail, but that made no difference. I also tried this myself, sending from Mail.app over to my PC's Outlook, and I do get that same problem. In Outlook the image is not coming through as an attachment, but as an image embedded into the body of the email. The reason this is an issue primarily is because the user is then unable to click "save as" and has to actually copy and paste it into some other program, which means the file is converted from jpg or png to the bmp format. But beyond that, most of my recipients don't even know how to copy and paste it into another program to save it that way anyway. They need the "save attachment as" functionality.

  • MX record configuration for hosted email?

    - by Paul Sanwald
    I am helping a friend with his website, and am having a problem with his webmail configuration, which I suspect is due to a misconfigured MX record. His domain is registered and hosted by hostmonster, they have a webmail option. A record: Host Points To TTL webmail 12.345.789.101 14400 CNAME: mail webmail.d.com 14400 MX Record: 0 @ mail.d.com 14400 I've created an email account on hostmonster, [email protected]: however, when I sent an email to this account, it appears to be routing to /dev/null. I know that it's not actually, but am unsure of the steps I can take to track this down? I've tried using dig, but am unsure where to start. How can I track down where this email is being routed to?

  • Linux - Scriptable email client?

    - by Phog
    Hi, I'm writing a simple UI for the visually impaired using a speech synthesizer. I've looked all over the internet for an email client which I can script to fit these purposes but to no avail. I believe several CLI email clients(eg MUTT) allow sending emails with command line arguments only. But I've yet to find a client that can download the emails, decode them and then dump them to a text file. The best candidate so far seems to be mailx, but it seems like it needs quite a lot of babysitting to fit my needs. Any suggestions for scripting-friendly email clients? Am I missing something fundamental about MUTT? Are there any libraries/programs that help me decode the MIME encoding used in todays emails from a maildir? Should I just bite the bullet and write a script for mailx? Thanks in advance.

  • How to make Outlook always show the full email id of a forwarded mail

    - by Firee
    Am currently using Outlook 2013. Several times, when a mail is forwarded to me, i only see the First/Last name of the person in the forwarded mail, not the email id. Is there a way to make Outlook always display the email id. I get these mails from people, who are also using Outlook but different versions. One solution which we have to resort to, is to attach the mail, rather than forward, that way it retains the email address, but this is cumbersome, and I cannot ask everyone to do this. This is similar to this question, but the answer selected does not work for me.

  • What is a good hosted email service?

    - by rhooligan
    I am looking for a hosted email service for a handful of email accounts. It needs to be very reliable and provide a nice web mail interface. I would like an admin where I can manage accounts. I've used Communigate before, it's functional but ugly. Exchange web mail is feature rich enough, but isn't as performant as the later two contestants. I am currently paying $50/yearly for hosted Gmail through Google. The features of the web email client are fine for personal use, but not flexible enough for professional use. The administration tools also suck. In short, I want a hosted service with a better experience than gmail or Communigate but is still speedy.

  • Email client supporting multiple accounts

    - by TGP1994
    I've been using Microsoft Outlook for a very long time, although one thing that has bugged me is how multiple email accounts are handled. As far as I can tell, there isn't a set and straightforward way of managing multiple accounts in one instance of outlook. For example, when I create an email, saving it as a draft will by default dump it into the first personal folder that I have open, which in my current case, is not where I want it. I would like all trash, spam, drafts, contacts, etc. etc. to be handled on a PF by PF basis. Now to my question: Is there a way to accomplish the task of email account "segregation" in Outlook (2007 is my current version), or is there another client that handles this in a more organized fashion? Note: I don't use most of the features in outlook (I hardly even need special formatting for my messages), I generally just send and read mail, and get a few attachments, so leaving Outlook wouldn't be too much of a stretch for me.

  • Email forwarding via spf record

    - by Y.G.J
    I have old-domain.co.il with several emails and a new-domain.co.il with the same email addresses. I don't want to connect my domain to a server via mx to make that transfer via email server. Is it possible to have a SPF record that get an email like [email protected] and transfer it to [email protected]? The new domain is on google apps and the old domain can be connected to the same apps, but how to do it, so emails will arrive only to the new one?

  • How to prevent a URL in an email I send from being auto-linked by the recipient's email client?

    - by gilly3
    When I type a URL into an email in Outlook, it automatically converts it to a hyperlink. I can, of course, remove the hyperlink from the context menu: But, then when the email is received and when I view it in my Sent Items folder, the urls are again converted to hyperlinks. How can I prevent this? Embedded images are no good because the URL must be copy and pasteable (among numerous other reasons that this approach is not great). And it must retain the formatting applied when I send it. This answer on stackoverflow shows a good trick for preventing auto linked urls when sending an email programmatically, but I'm looking for a way to do this from the UI. Perhaps there a way to edit the HTML of the message before it is sent? If not, I guess I'm off to write an Outlook Add-in.

  • Mystery "users" email group

    - by dangowans
    This morning, our entire company received a spam message sent to [email protected], where "ourdomain.on.ca" is our actual domain. There is a distinguished name that this could correspond to: CN=Users,DC=ourdomain,DC=on,DC=ca Looking at the attributes though, there is no mail, no proxyAddresses, no signs that there is a mailbox configured there. I did some LDAP queries, searching for: (proxyAddresses=smtp:[email protected]) ([email protected]) But am not seeing any records. (I also search for known email addresses to ensure the tree was being searched properly.) We are running Exchange 2003. Is there another place to look for group email addresses? Is it possible that the distinguished name is being automatically translated to an email address?

  • Encoding a email address that can be used as part of a URL in codeigniter

    - by freedayum
    Is there a way to encode a email address that can be used as a part of a url in codeigniter?. I need to decode back the email address from the url. What I am trying to do is just a -forgotten password recovery- thing. I send a confirmation link to the user's email address, the link needs to be like ../encodedEmail/forgottenPasswordCode (with the forgottenPasswordCode updated in the db for the user with the submitted email). When the user visits that link, I decode the email(if the email - forgottenPasswordCode pair is in the table), i allow them to reset their password (and i reset forgottenPasswordCode back to null). I could just do a loop -checking the table with a select query- (or) -set that forgottenPasswordCode column unique, so i keep generating on a insert failure(would that be a lot faster ?)- until I generate a forgottenPasswordCode that doesn't already exist in the table. But the guy I do this for would not accept it this way:). He wants the checking be done with the user's email, he thinks its much faster. I am working with codeigniter, I used its encode() function, it seems to produce characters like '-slashes-' at times that breaks the encoded-email-string. Any other ideas?

  • Trouble with jquery email form submitHandler

    - by Robert
    Here is the code I'm using for the submitHandler: submitHandler: function() { $('.holder').fadeOut('slow'); $('#loading').fadeIn('slow'); $.post('email.php',{name:$('#em_name').val(), email:$('#em_email').val(), message:$('#em_message').val()}, function(data){ $('#loading').css({display:'none'}); if( data == 'success') { $('#callback').show().append('Message delivered successfully'); $('#emailform').slideUp('slow'); } else { $('#callback').show().append('Sorry but your message could not be sent, try again later'); } }); } This isn't working when used in conjunction with this php: <?php $name = stripcslashes($_POST['name']); $emailAddr = stripcslashes($_POST['email']); $message = stripcslashes($_POST['message']); $email = "Message: $message \r \n From: $name \r \n Reply to: $emailAddr"; $to = '[email protected]'; $subject = 'Message from example'; //validate the email address on the server side if(eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $emailAddr) ) { //if successful lets send the message mail($to, $subject, $email); echo('success'); //return success callback } else { echo('An invalid email address was entered'); //email was not valid } ?> Does anyone have any suggestions as to why this isn't working like it should. It seems to just lock up when I submit. Any help would be appreciated. Thanks!

  • Troubleshooting PHP email sending?

    - by darkAsPitch
    I created a website that occasionally emails users when they register/change their password/etc. Every other person however cannot or does not receive the emails. They are telling me that they are not even hitting their spam folders. I don't know a ton about MX records or email sending, but when I "Edit DNS Zone" for this domain in particular there is 1 MX record listed there. How do you go about troubleshooting botched PHP mail actions? UPDATE: Here is my super-simple php mailing code: $subject = "Subject Here"; $message = "Emails Message"; $to = $verified_user_data["email_address"]; $headers = "From: [email protected]\r\n" . "Reply-To: [email protected]\r\n" . "X-Mailer: PHP/" . phpversion(); //returns true on success, false on failure $email_result = mail($to, $subject, $message, $headers); re: "are you saying that some do and some do not?" @ Jacob Yes, basically. I send the emails containing the user's login username/password using similar code above. And I sell to fairly tech-savvy people. About 50% of the time, my customers claim they cannot find their welcome emails in their inbox OR in their spam box. It's as if it never arrived. I have the largest problem with Yahoo email addresses accepting my emails or so it seems. re: "The MX record at your end doesn't factor in, although the SPF record (or lack of it) will. How much access and control do you have on the server itself?" @ John Gardeniers I rent a dedicated server from Codero. Running CentOS 5, WHM + cPanel. I have full root access to the entire thing. Don't know much about MX records and/or SPF records. I just want the PHP mail function to work. It doesn't say much about that on the php mail function's help page. re: "What are you using for the SMTP server?" @ JonLim No idea. I use the code above when I need to fire off an email to a loyal customer, and that's it. Do I need to be worrying about SMTP servers? re: "Could be many, many things. Can you describe how you're sending mail in your code? i.e. are you relaying off of another mail server somewhere, using the local sendmail or postfix? Any consistency in domains that can/cannot receive email? Do you have a PTR record setup from the IP address that you're sending mail out as? What about SPF records?" @ gravyface I just described my simple code above! I believe I have been having the most trouble with Yahoo domains, however "independent" domains (probably running spamassasin) ex. [email protected] as opposed to [email protected] seem to give a lot of trouble as well. I do not know if I have a PTR record setup from the IP address I'm sending my mail from. It's probably the same IP address that I setup my domain on, because I didn't do anything extra special. No idea about SPF records either, where can I go to create one? Side Note: It's a crying shame what havoc the spammers have brought upon our beloved email system.

  • Android Google-Shopping API force closes while parsing

    - by Sam Jackson
    I'm trying to send a request to the Google-Shopping API with the following static method which I think is working: public static String GET_TITLE(String url) throws JSONException { InputStream is = null; String result = ""; JSONObject jArray = null; // http post try { HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(url); HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); is = entity.getContent(); } catch(Exception e) { Log.e("log_tag", "Error in http connection "+e.toString()); } The URL I'm passing is this BTW: https://www.googleapis.com/shopping/search/v1/public/products/country=US&q=shirts&alt=json &rankBy=relevancy&key=AIzaSyDRKgGmJrdG6pV6DIg2m-nmIbXydxvpjww Next I try to parse this response (where I think the problem comes in) in the same method: try { jArray = new JSONObject(result); } catch(JSONException e){ Log.e("log_tag", "Error parsing data "+e.toString()); } JSONObject itemObject = jArray.getJSONObject("items"); JSONObject productObject = itemObject.getJSONObject("product"); String attributeGoogleId = productObject.getString("googleId"); String attributeProviderId = productObject.getString("providerId"); String attributeTitle = productObject.getString("title");*/ String attributePrice = productObject.getString("price"); JSONObject popupObject = productObject.getJSONObject("popup"); return attributeTitle; } This has been so frustrating, I know it should be simple but everywhere I look I just can't quite get it to work, I'm not exactly sure what the error is since I'm testing it on my HTC Desire because my emulator gives an 'invalid command-line parameter' error when starting, but that's a different issue, anyway, thanks in advance!

  • Using JSON.NET for dynamic JSON parsing

    - by Rick Strahl
    With the release of ASP.NET Web API as part of .NET 4.5 and MVC 4.0, JSON.NET has effectively pushed out the .NET native serializers to become the default serializer for Web API. JSON.NET is vastly more flexible than the built in DataContractJsonSerializer or the older JavaScript serializer. The DataContractSerializer in particular has been very problematic in the past because it can't deal with untyped objects for serialization - like values of type object, or anonymous types which are quite common these days. The JavaScript Serializer that came before it actually does support non-typed objects for serialization but it can't do anything with untyped data coming in from JavaScript and it's overall model of extensibility was pretty limited (JavaScript Serializer is what MVC uses for JSON responses). JSON.NET provides a robust JSON serializer that has both high level and low level components, supports binary JSON, JSON contracts, Xml to JSON conversion, LINQ to JSON and many, many more features than either of the built in serializers. ASP.NET Web API now uses JSON.NET as its default serializer and is now pulled in as a NuGet dependency into Web API projects, which is great. Dynamic JSON Parsing One of the features that I think is getting ever more important is the ability to serialize and deserialize arbitrary JSON content dynamically - that is without mapping the JSON captured directly into a .NET type as DataContractSerializer or the JavaScript Serializers do. Sometimes it isn't possible to map types due to the differences in languages (think collections, dictionaries etc), and other times you simply don't have the structures in place or don't want to create them to actually import the data. If this topic sounds familiar - you're right! I wrote about dynamic JSON parsing a few months back before JSON.NET was added to Web API and when Web API and the System.Net HttpClient libraries included the System.Json classes like JsonObject and JsonArray. With the inclusion of JSON.NET in Web API these classes are now obsolete and didn't ship with Web API or the client libraries. I re-linked my original post to this one. In this post I'll discus JToken, JObject and JArray which are the dynamic JSON objects that make it very easy to create and retrieve JSON content on the fly without underlying types. Why Dynamic JSON? So, why Dynamic JSON parsing rather than strongly typed parsing? Since applications are interacting more and more with third party services it becomes ever more important to have easy access to those services with easy JSON parsing. Sometimes it just makes lot of sense to pull just a small amount of data out of large JSON document received from a service, because the third party service isn't directly related to your application's logic most of the time - and it makes little sense to map the entire service structure in your application. For example, recently I worked with the Google Maps Places API to return information about businesses close to me (or rather the app's) location. The Google API returns a ton of information that my application had no interest in - all I needed was few values out of the data. Dynamic JSON parsing makes it possible to map this data, without having to map the entire API to a C# data structure. Instead I could pull out the three or four values I needed from the API and directly store it on my business entities that needed to receive the data - no need to map the entire Maps API structure. Getting JSON.NET The easiest way to use JSON.NET is to grab it via NuGet and add it as a reference to your project. You can add it to your project with: PM> Install-Package Newtonsoft.Json From the Package Manager Console or by using Manage NuGet Packages in your project References. As mentioned if you're using ASP.NET Web API or MVC 4 JSON.NET will be automatically added to your project. Alternately you can also go to the CodePlex site and download the latest version including source code: http://json.codeplex.com/ Creating JSON on the fly with JObject and JArray Let's start with creating some JSON on the fly. It's super easy to create a dynamic object structure with any of the JToken derived JSON.NET objects. The most common JToken derived classes you are likely to use are JObject and JArray. JToken implements IDynamicMetaProvider and so uses the dynamic  keyword extensively to make it intuitive to create object structures and turn them into JSON via dynamic object syntax. Here's an example of creating a music album structure with child songs using JObject for the base object and songs and JArray for the actual collection of songs:[TestMethod] public void JObjectOutputTest() { // strong typed instance var jsonObject = new JObject(); // you can explicitly add values here using class interface jsonObject.Add("Entered", DateTime.Now); // or cast to dynamic to dynamically add/read properties dynamic album = jsonObject; album.AlbumName = "Dirty Deeds Done Dirt Cheap"; album.Artist = "AC/DC"; album.YearReleased = 1976; album.Songs = new JArray() as dynamic; dynamic song = new JObject(); song.SongName = "Dirty Deeds Done Dirt Cheap"; song.SongLength = "4:11"; album.Songs.Add(song); song = new JObject(); song.SongName = "Love at First Feel"; song.SongLength = "3:10"; album.Songs.Add(song); Console.WriteLine(album.ToString()); } This produces a complete JSON structure: { "Entered": "2012-08-18T13:26:37.7137482-10:00", "AlbumName": "Dirty Deeds Done Dirt Cheap", "Artist": "AC/DC", "YearReleased": 1976, "Songs": [ { "SongName": "Dirty Deeds Done Dirt Cheap", "SongLength": "4:11" }, { "SongName": "Love at First Feel", "SongLength": "3:10" } ] } Notice that JSON.NET does a nice job formatting the JSON, so it's easy to read and paste into blog posts :-). JSON.NET includes a bunch of configuration options that control how JSON is generated. Typically the defaults are just fine, but you can override with the JsonSettings object for most operations. The important thing about this code is that there's no explicit type used for holding the values to serialize to JSON. Rather the JSON.NET objects are the containers that receive the data as I build up my JSON structure dynamically, simply by adding properties. This means this code can be entirely driven at runtime without compile time restraints of structure for the JSON output. Here I use JObject to create a album 'object' and immediately cast it to dynamic. JObject() is kind of similar in behavior to ExpandoObject in that it allows you to add properties by simply assigning to them. Internally, JObject values are stored in pseudo collections of key value pairs that are exposed as properties through the IDynamicMetaObject interface exposed in JSON.NET's JToken base class. For objects the syntax is very clean - you add simple typed values as properties. For objects and arrays you have to explicitly create new JObject or JArray, cast them to dynamic and then add properties and items to them. Always remember though these values are dynamic - which means no Intellisense and no compiler type checking. It's up to you to ensure that the names and values you create are accessed consistently and without typos in your code. Note that you can also access the JObject instance directly (not as dynamic) and get access to the underlying JObject type. This means you can assign properties by string, which can be useful for fully data driven JSON generation from other structures. Below you can see both styles of access next to each other:// strong type instance var jsonObject = new JObject(); // you can explicitly add values here jsonObject.Add("Entered", DateTime.Now); // expando style instance you can just 'use' properties dynamic album = jsonObject; album.AlbumName = "Dirty Deeds Done Dirt Cheap"; JContainer (the base class for JObject and JArray) is a collection so you can also iterate over the properties at runtime easily:foreach (var item in jsonObject) { Console.WriteLine(item.Key + " " + item.Value.ToString()); } The functionality of the JSON objects are very similar to .NET's ExpandObject and if you used it before, you're already familiar with how the dynamic interfaces to the JSON objects works. Importing JSON with JObject.Parse() and JArray.Parse() The JValue structure supports importing JSON via the Parse() and Load() methods which can read JSON data from a string or various streams respectively. Essentially JValue includes the core JSON parsing to turn a JSON string into a collection of JsonValue objects that can be then referenced using familiar dynamic object syntax. Here's a simple example:public void JValueParsingTest() { var jsonString = @"{""Name"":""Rick"",""Company"":""West Wind"", ""Entered"":""2012-03-16T00:03:33.245-10:00""}"; dynamic json = JValue.Parse(jsonString); // values require casting string name = json.Name; string company = json.Company; DateTime entered = json.Entered; Assert.AreEqual(name, "Rick"); Assert.AreEqual(company, "West Wind"); } The JSON string represents an object with three properties which is parsed into a JObject class and cast to dynamic. Once cast to dynamic I can then go ahead and access the object using familiar object syntax. Note that the actual values - json.Name, json.Company, json.Entered - are actually of type JToken and I have to cast them to their appropriate types first before I can do type comparisons as in the Asserts at the end of the test method. This is required because of the way that dynamic types work which can't determine the type based on the method signature of the Assert.AreEqual(object,object) method. I have to either assign the dynamic value to a variable as I did above, or explicitly cast ( (string) json.Name) in the actual method call. The JSON structure can be much more complex than this simple example. Here's another example of an array of albums serialized to JSON and then parsed through with JsonValue():[TestMethod] public void JsonArrayParsingTest() { var jsonString = @"[ { ""Id"": ""b3ec4e5c"", ""AlbumName"": ""Dirty Deeds Done Dirt Cheap"", ""Artist"": ""AC/DC"", ""YearReleased"": 1976, ""Entered"": ""2012-03-16T00:13:12.2810521-10:00"", ""AlbumImageUrl"": ""http://ecx.images-amazon.com/images/I/61kTaH-uZBL._AA115_.jpg"", ""AmazonUrl"": ""http://www.amazon.com/gp/product/…ASIN=B00008BXJ4"", ""Songs"": [ { ""AlbumId"": ""b3ec4e5c"", ""SongName"": ""Dirty Deeds Done Dirt Cheap"", ""SongLength"": ""4:11"" }, { ""AlbumId"": ""b3ec4e5c"", ""SongName"": ""Love at First Feel"", ""SongLength"": ""3:10"" }, { ""AlbumId"": ""b3ec4e5c"", ""SongName"": ""Big Balls"", ""SongLength"": ""2:38"" } ] }, { ""Id"": ""7b919432"", ""AlbumName"": ""End of the Silence"", ""Artist"": ""Henry Rollins Band"", ""YearReleased"": 1992, ""Entered"": ""2012-03-16T00:13:12.2800521-10:00"", ""AlbumImageUrl"": ""http://ecx.images-amazon.com/images/I/51FO3rb1tuL._SL160_AA160_.jpg"", ""AmazonUrl"": ""http://www.amazon.com/End-Silence-Rollins-Band/dp/B0000040OX/ref=sr_1_5?ie=UTF8&qid=1302232195&sr=8-5"", ""Songs"": [ { ""AlbumId"": ""7b919432"", ""SongName"": ""Low Self Opinion"", ""SongLength"": ""5:24"" }, { ""AlbumId"": ""7b919432"", ""SongName"": ""Grip"", ""SongLength"": ""4:51"" } ] } ]"; JArray jsonVal = JArray.Parse(jsonString) as JArray; dynamic albums = jsonVal; foreach (dynamic album in albums) { Console.WriteLine(album.AlbumName + " (" + album.YearReleased.ToString() + ")"); foreach (dynamic song in album.Songs) { Console.WriteLine("\t" + song.SongName); } } Console.WriteLine(albums[0].AlbumName); Console.WriteLine(albums[0].Songs[1].SongName); } JObject and JArray in ASP.NET Web API Of course these types also work in ASP.NET Web API controller methods. If you want you can accept parameters using these object or return them back to the server. The following contrived example receives dynamic JSON input, and then creates a new dynamic JSON object and returns it based on data from the first:[HttpPost] public JObject PostAlbumJObject(JObject jAlbum) { // dynamic input from inbound JSON dynamic album = jAlbum; // create a new JSON object to write out dynamic newAlbum = new JObject(); // Create properties on the new instance // with values from the first newAlbum.AlbumName = album.AlbumName + " New"; newAlbum.NewProperty = "something new"; newAlbum.Songs = new JArray(); foreach (dynamic song in album.Songs) { song.SongName = song.SongName + " New"; newAlbum.Songs.Add(song); } return newAlbum; } The raw POST request to the server looks something like this: POST http://localhost/aspnetwebapi/samples/PostAlbumJObject HTTP/1.1User-Agent: FiddlerContent-type: application/jsonHost: localhostContent-Length: 88 {AlbumName: "Dirty Deeds",Songs:[ { SongName: "Problem Child"},{ SongName: "Squealer"}]} and the output that comes back looks like this: {  "AlbumName": "Dirty Deeds New",  "NewProperty": "something new",  "Songs": [    {      "SongName": "Problem Child New"    },    {      "SongName": "Squealer New"    }  ]} The original values are echoed back with something extra appended to demonstrate that we're working with a new object. When you receive or return a JObject, JValue, JToken or JArray instance in a Web API method, Web API ignores normal content negotiation and assumes your content is going to be received and returned as JSON, so effectively the parameter and result type explicitly determines the input and output format which is nice. Dynamic to Strong Type Mapping You can also map JObject and JArray instances to a strongly typed object, so you can mix dynamic and static typing in the same piece of code. Using the 2 Album jsonString shown earlier, the code below takes an array of albums and picks out only a single album and casts that album to a static Album instance.[TestMethod] public void JsonParseToStrongTypeTest() { JArray albums = JArray.Parse(jsonString) as JArray; // pick out one album JObject jalbum = albums[0] as JObject; // Copy to a static Album instance Album album = jalbum.ToObject<Album>(); Assert.IsNotNull(album); Assert.AreEqual(album.AlbumName,jalbum.Value<string>("AlbumName")); Assert.IsTrue(album.Songs.Count > 0); } This is pretty damn useful for the scenario I mentioned earlier - you can read a large chunk of JSON and dynamically walk the property hierarchy down to the item you want to access, and then either access the specific item dynamically (as shown earlier) or map a part of the JSON to a strongly typed object. That's very powerful if you think about it - it leaves you in total control to decide what's dynamic and what's static. Strongly typed JSON Parsing With all this talk of dynamic let's not forget that JSON.NET of course also does strongly typed serialization which is drop dead easy. Here's a simple example on how to serialize and deserialize an object with JSON.NET:[TestMethod] public void StronglyTypedSerializationTest() { // Demonstrate deserialization from a raw string var album = new Album() { AlbumName = "Dirty Deeds Done Dirt Cheap", Artist = "AC/DC", Entered = DateTime.Now, YearReleased = 1976, Songs = new List<Song>() { new Song() { SongName = "Dirty Deeds Done Dirt Cheap", SongLength = "4:11" }, new Song() { SongName = "Love at First Feel", SongLength = "3:10" } } }; // serialize to string string json2 = JsonConvert.SerializeObject(album,Formatting.Indented); Console.WriteLine(json2); // make sure we can serialize back var album2 = JsonConvert.DeserializeObject<Album>(json2); Assert.IsNotNull(album2); Assert.IsTrue(album2.AlbumName == "Dirty Deeds Done Dirt Cheap"); Assert.IsTrue(album2.Songs.Count == 2); } JsonConvert is a high level static class that wraps lower level functionality, but you can also use the JsonSerializer class, which allows you to serialize/parse to and from streams. It's a little more work, but gives you a bit more control. The functionality available is easy to discover with Intellisense, and that's good because there's not a lot in the way of documentation that's actually useful. Summary JSON.NET is a pretty complete JSON implementation with lots of different choices for JSON parsing from dynamic parsing to static serialization, to complex querying of JSON objects using LINQ. It's good to see this open source library getting integrated into .NET, and pushing out the old and tired stock .NET parsers so that we finally have a bit more flexibility - and extensibility - in our JSON parsing. Good to go!

  • Simple libxml2 HTML parsing example, using Objective-c, Xcode, and HTMLparser.h

    - by Stu
    Please can somebody show me a simple example of parsing some HTML using libxml. #import <libxml2/libxml/HTMLparser.h> NSString *html = @"<ul><li><input type=\"image\" name=\"input1\" value=\"string1value\" /></li><li><input type=\"image\" name=\"input2\" value=\"string2value\" /></li></ul><span class=\"spantext\"><b>Hello World 1</b></span><span class=\"spantext\"><b>Hello World 2</b></span>"; 1) Say I want to parse the value of the input whose name = input2. Should output "string2value". 2) Say I want to parse the inner contents of each span tag whose class = spantext. Should output: "Hello World 1" and "Hello World 2".

  • How to parse invalid HTML with Perl?

    - by bodacydo
    I maintain a database of articles with HTML formatting. Unfortunately the editors who wrote articles didn't know proper HTML, so they often have written stuff like: <div class="highlight"><html><head></head><body><p>Note that ...</p></html></div> I tried using HTML::TreeBuilder to parse this HTML but after parsing it and dumping the resulting tree, all the elements between <div class="highlight">...</div> are gone. I'm left with just <div class="highlight"></div>. The editors often have also done things like: <div class="article"><style>@font-face { font-family: "Cambria"; }</style>Article starts here</div> Parsing this with HTML::TreeBuilder results in empty <div class="article"></div> again. Any ideas how to approach this broken HTML and actually make sense out of it?

  • Creating Google+ profile has changed a Google Apps for Business email name

    - by inbanco
    We use Google Apps for business for email, docs etc. For one account [email protected] I setup a Google+ profile but didn't realise it would change the name of the email account Was: From email name: "Sydney Branch" Email address: [email protected] Now: From email name: "John Smith" Email address: [email protected] I'd like to change it back. The name hasn't changed though in the Google Apps domain management email section though, so i don't know what's going on and don't want to lose that email address/account through suspension. I couldn't care less about losing Google+, i'm happy to remove that profile, but would it revert the name?

  • Migrating Email to new hosting.

    - by Ben C
    I've made a site for a charity, and now have to move hosting for them. They have 5 or so email addresses on their current hosting account, which will of course need to move too. What's the best way to migrate their email addresses to the new server without too much hassle for them? They use POP3, so should I just create the account on the new server and then get them to update their settings? That won't remove their old emails from Outlook Express, will it?
