• Google App Engine + Form Validation

  - by Iwona

  Hi, I would like to do google app engine form validation but I dont know how to do it? I tried like this: from google.appengine.ext.db import djangoforms from django import newforms as forms class SurveyForm(forms.Form): occupations_choices = ( ('1', ""), ('2', "Undergraduate student"), ('3', "Postgraduate student (MSc)"), ('4', "Postgraduate student (PhD)"), ('5', "Lab assistant"), ('6', "Technician"), ('7', "Lecturer"), ('8', "Other" ) ) howreach_choices = ( ('1', ""), ('2', "Typed the URL directly"), ('3', "Site is bookmarked"), ('4', "A search engine"), ('5', "A link from another site"), ('6', "From a book"), ('7', "Other") ) boxes_choices = ( ("des", "Website Design"), ("svr", "Web Server Administration"), ("com", "Electronic Commerce"), ("mkt", "Web Marketing/Advertising"), ("edu", "Web-Related Education") ) name = forms.CharField(label='Name', max_length=100, required=True) email = forms.EmailField(label='Your Email Address:') occupations = forms.ChoiceField(choices=occupations_choices, label='What is your occupation?') howreach = forms.ChoiceField(choices=howreach_choices, label='How did you reach this site?') # radio buttons 1-5 rating = forms.ChoiceField(choices=range(1,6), label='What is your occupation?', widget=forms.RadioSelect) boxes = forms.ChoiceField(choices=boxes_choices, label='Are you involved in any of the following? (check all that apply):', widget=forms.CheckboxInput) comment = forms.CharField(widget=forms.Textarea, required=False) And I wanted to display it like this: template_values = { 'url' : url, 'url_linktext' : url_linktext, 'userName' : userName, 'item1' : SurveyForm() } And I have this error message: Traceback (most recent call last): File "C:\Program Files\Google\google_appengine\google\appengine\ext\webapp_init_.py", line 515, in call handler.get(*groups) File "C:\Program Files\Google\google_appengine\demos\b00213576\main.py", line 144, in get self.response.out.write(template.render(path, template_values)) File "C:\Program Files\Google\google_appengine\google\appengine\ext\webapp\template.py", line 143, in render return t.render(Context(template_dict)) File "C:\Program Files\Google\google_appengine\google\appengine\ext\webapp\template.py", line 183, in wrap_render return orig_render(context) File "C:\Program Files\Google\google_appengine\lib\django\django\template_init_.py", line 168, in render return self.nodelist.render(context) File "C:\Program Files\Google\google_appengine\lib\django\django\template_init_.py", line 705, in render bits.append(self.render_node(node, context)) File "C:\Program Files\Google\google_appengine\lib\django\django\template_init_.py", line 718, in render_node return(node.render(context)) File "C:\Program Files\Google\google_appengine\lib\django\django\template\defaulttags.py", line 209, in render return self.nodelist_true.render(context) File "C:\Program Files\Google\google_appengine\lib\django\django\template_init_.py", line 705, in render bits.append(self.render_node(node, context)) File "C:\Program Files\Google\google_appengine\lib\django\django\template_init_.py", line 718, in render_node return(node.render(context)) File "C:\Program Files\Google\google_appengine\lib\django\django\template_init_.py", line 768, in render return self.encode_output(output) File "C:\Program Files\Google\google_appengine\lib\django\django\template_init_.py", line 757, in encode_output return str(output) File "C:\Program Files\Google\google_appengine\lib\django\django\newforms\util.py", line 26, in str return self.unicode().encode(settings.DEFAULT_CHARSET) File "C:\Program Files\Google\google_appengine\lib\django\django\newforms\forms.py", line 73, in unicode return self.as_table() File "C:\Program Files\Google\google_appengine\lib\django\django\newforms\forms.py", line 144, in as_table return self._html_output(u'%(label)s%(errors)s%(field)s%(help_text)s', u'%s', '', u'%s', False) File "C:\Program Files\Google\google_appengine\lib\django\django\newforms\forms.py", line 129, in _html_output output.append(normal_row % {'errors': bf_errors, 'label': label, 'field': unicode(bf), 'help_text': help_text}) File "C:\Program Files\Google\google_appengine\lib\django\django\newforms\forms.py", line 232, in unicode value = value.str() File "C:\Program Files\Google\google_appengine\lib\django\django\newforms\util.py", line 26, in str return self.unicode().encode(settings.DEFAULT_CHARSET) File "C:\Program Files\Google\google_appengine\lib\django\django\newforms\widgets.py", line 246, in unicode return u'\n%s\n' % u'\n'.join([u'%s' % w for w in self]) File "C:\Program Files\Google\google_appengine\lib\django\django\newforms\widgets.py", line 238, in iter yield RadioInput(self.name, self.value, self.attrs.copy(), choice, i) File "C:\Program Files\Google\google_appengine\lib\django\django\newforms\widgets.py", line 212, in init self.choice_value = smart_unicode(choice[0]) TypeError: 'int' object is unsubscriptable Do You have any idea how I can do this validation in different case? I have tried to do it using this kind of: class ItemUserAnswer(djangoforms.ModelForm): class Meta: model = UserAnswer But I dont know how to add extra labels to this form and it is displayed in one line. Do You have any suggestions? Thanks a lot as it making me crazy why it is still not working:/

• XSLT Select all nodes containing a specific substing

  - by Mike

  I'm trying to write an XPath that will select certain nodes that contain a specific word. In this case the word is, "Lockwood". The correct answer is 3. Both of these paths give me 3. count(//*[contains(./*,'Lockwood')]) count(BusinessLetter/*[contains(../*,'Lockwood')]) But when I try to output the text of each specific node //*[contains(./*,'Lockwood')][1] //*[contains(./*,'Lockwood')][2] //*[contains(./*,'Lockwood')][3] Node 1 ends up containing all the text and nodes 2 and 3 are blank.

But i am unable to construct logic for retrieving this value.I want to make it dynamic. Please help me on this. Thanks

• Opinions on Dual-Salt authentication for low sensitivity user accounts?

  - by Heleon

  EDIT - Might be useful for someone in the future... Looking around the bcrypt class in php a little more, I think I understand what's going on, and why bcrypt is secure. In essence, I create a random blowfish salt, which contains the number of crypt rounds to perform during the encryption step, which is then hashed using the crypt() function in php. There is no need for me to store the salt I used in the database, because it's not directly needed to decrypt, and the only way to gain a password match to an email address (without knowing the salt values or number of rounds) would be to brute force plain text passwords against the hash stored in the database using the crypt() function to verify, which, if you've got a strong password, would just be more effort than it's worth for the user information i'm storing... I am currently working on a web project requiring user accounts. The application is CodeIgniter on the server side, so I am using Ion Auth as the authentication library. I have written an authentication system before, where I used 2 salts to secure the passwords. One was a server-wide salt which sat as an environment variable in the .htaccess file, and the other was a randomly generated salt which was created at user signup. This was the method I used in that authentication system for hashing the password: $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; //create a random string to be used as the random salt for the password hash $size = strlen($chars); for($i = 0; $i < 22; $i++) { $str .= $chars[rand(0, $size - 1)]; } //create the random salt to be used for the crypt $r_blowfish_salt = "$2a$12$" . $str . "$"; //grab the website salt $salt = getenv('WEBSITE_SALT'); //combine the website salt, and the password $password_to_hash = $pwd . $salt; //crypt the password string using blowfish $password = crypt($password_to_hash, $r_blowfish_salt); I have no idea whether this has holes in it or not, but regardless, I moved over to Ion Auth for a more complete set of functions to use with CI. I noticed that Ion only uses a single salt as part of its hashing mechanism (although does recommend that encryption_key is set in order to secure the database session.) The information that will be stored in my database is things like name, email address, location by country, some notes (which will be recommended that they do not contain sensitive information), and a link to a Facebook, Twitter or Flickr account. Based on this, i'm not convinced it's necessary for me to have an SSL connection on the secure pages of my site. My question is, is there a particular reason why only 1 salt is being used as part as the Ion Auth library? Is it implied that I write my own additional salting in front of the functionality it provides, or am I missing something? Furthermore, is it even worth using 2 salts, or once an attacker has the random salt and the hashed password, are all bets off anyway? (I assume not, but worth checking if i'm worrying about nothing...)

• Deleting xml file using radio value

  - by ???? ???

  i using php to delete file, but i got table loop like this: <table border="0" width="100%" cellpadding="0" cellspacing="0" id="product-table"> <tr class="bg_tableheader"> <th class="table-header-check"><a id="toggle-all" ></a> </th> <th class="table-header-check"><a href="#"><font color="white">Username</font></a> </th> <th class="table-header-check"><a href="#"><font color="white">First Name</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Last Name</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Email</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Group</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Birthday</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Gender</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Age</font></a></th> <th class="table-header-check"><a href="#"><font color="white">Country</font></a></th> </tr> <?php $files = glob('users/*.xml'); foreach($files as $file){ $xml = new SimpleXMLElement($file, 0, true); echo ' <tr> <td></td> <form action="" method="post"> <td class="alternate-row1"><input type="radio" name="file_name" value="'. basename($file, '.xml') .'" />'. basename($file, '.xml') .'</td> <td>'. $xml->name .'&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp</td> <td class="alternate-row1">'. $xml->lastname .'</td> <td>'. $xml->email .'</td> <td class="alternate-row1">'. $xml->level .'</td> <td>'. $xml->birthday .'</td> <td class="alternate-row1">'. $xml->gender .'</td> <td>'. $xml->age .'</td> <td class="alternate-row1">'. $xml->country .'</td> </tr>'; } ?> </table> </div> <?php if(isset($_POST['file_name'])){ unlink('users/'.$_POST['file_name']); } ?> <input type="submit" value="Delete" /> </form> so as you can see i got radio value set has basename (xml file name) but from some reason it not working, any idea why is that? Thanks in advance.

• MySQL and INT auto_increment fields

  - by PHPguy

  Hello folks, I'm developing in LAMP (Linux+Apache+MySQL+PHP) since I remember myself. But one question was bugging me for years now. I hope you can help me to find an answer and point me into the right direction. Here is my challenge: Say, we are creating a community website, where we allow our users to register. The MySQL table where we store all users would look then like this: CREATE TABLE `users` ( `uid` int(2) unsigned NOT NULL auto_increment COMMENT 'User ID', `name` varchar(20) NOT NULL, `password` varchar(32) NOT NULL COMMENT 'Password is saved as a 32-bytes hash, never in plain text', `email` varchar(64) NOT NULL, `created` int(11) unsigned NOT NULL default '0' COMMENT 'Timestamp of registration', `updated` int(11) unsigned NOT NULL default '0' COMMENT 'Timestamp of profile update, e.g. change of email', PRIMARY KEY (`uid`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; So, from this snippet you can see that we have a unique and automatically incrementing for every new user 'uid' field. As on every good and loyal community website we need to provide users with possibility to completely delete their profile if they want to cancel their participation in our community. Here comes my problem. Let's say we have 3 registered users: Alice (uid = 1), Bob (uid = 2) and Chris (uid = 3). Now Bob want to delete his profile and stop using our community. If we delete Bob's profile from the 'users' table then his missing 'uid' will create a gap which will be never filled again. In my opinion it's a huge waste of uid's. I see 3 possible solutions here: 1) Increase the capacity of the 'uid' field in our table from SMALLINT (int(2)) to, for example, BIGINT (int(8)) and ignore the fact that some of the uid's will be wasted. 2) introduce the new field 'is_deleted', which will be used to mark deleted profiles (but keep them in the table, instead of deleting them) to re-utilize their uid's for newly registered users. The table will look then like this: CREATE TABLE `users` ( `uid` int(2) unsigned NOT NULL auto_increment COMMENT 'User ID', `name` varchar(20) NOT NULL, `password` varchar(32) NOT NULL COMMENT 'Password is saved as a 32-bytes hash, never in plain text', `email` varchar(64) NOT NULL, `is_deleted` int(1) unsigned NOT NULL default '0' COMMENT 'If equal to "1" then the profile has been deleted and will be re-used for new registrations', `created` int(11) unsigned NOT NULL default '0' COMMENT 'Timestamp of registration', `updated` int(11) unsigned NOT NULL default '0' COMMENT 'Timestamp of profile update, e.g. change of email', PRIMARY KEY (`uid`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; 3) Write a script to shift all following user records once a previous record has been deleted. E.g. in our case when Bob (uid = 2) decides to remove his profile, we would replace his record with the record of Chris (uid = 3), so that uid of Chris becomes qual to 2 and mark (is_deleted = '1') the old record of Chris as vacant for the new users. In this case we keep the chronological order of uid's according to the registration time, so that the older users have lower uid's. Please, advice me now which way is the right way to handle the gaps in the auto_increment fields. This is just one example with users, but such cases occur very often in my programming experience. Thanks in advance!

• Strange problem with Google App Engine Java Mail

  - by Velu

  Hi, I'm using the MailService feature of Google App Engine in my application. It works fine in one application without any issues. But the same code doesn't work in another app. I'm not able to figure it out. Please help. Following is the piece of code that I use to send mail. public static void sendHTMLEmail(String from, String fromName, String to, String toName, String subject, String body) { _logger.info("entering ..."); Properties props = new Properties(); Session session = Session.getDefaultInstance(props, null); _logger.info("got mail session ..."); String htmlBody = body; try { Message msg = new MimeMessage(session); _logger.info("created mimemessage ..."); msg.setFrom(new InternetAddress(from, fromName)); _logger.info("from is set ..."); msg.addRecipient(Message.RecipientType.TO, new InternetAddress( to, toName)); _logger.info("recipient is set ..."); msg.setSubject(subject); _logger.info("subject is set ..."); Multipart mp = new MimeMultipart(); MimeBodyPart htmlPart = new MimeBodyPart(); htmlPart.setContent(htmlBody, "text/html"); mp.addBodyPart(htmlPart); _logger.info("body part added ..."); msg.setContent(mp); _logger.info("content is set ..."); Transport.send(msg); _logger.info("email sent successfully."); } catch (AddressException e) { e.printStackTrace(); } catch (MessagingException e) { e.printStackTrace(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); System.err.println(e.getMessage()); } } When I look at the log (on the server admin console), it prints the statement "content is set ..." and after that there is nothing in the log. The mail is not sent. At times I get the following error after the above statement is printed (and the mail is not sent). com.google.appengine.repackaged.com.google.common.base.internal.Finalizer getInheritableThreadLocalsField: Couldn't access Thread.inheritableThreadLocals. Reference finalizer threads will inherit thread local values. But the mail quota usage keeps increasing. Remember, this works fine in one application, but not in other. I'm using the same set of email addresses in both the apps (for from and to). I'm really stuck with this. Appreciate any help. Thank you. Velu

• swap a div to an embed form when user tweets using the @anywhere function box

  - by Jeff

  I'm using the @anywhere twitter function on the front page of my site (vocabbomb.com) and right now it works great to allow users to tweet straight away. Problem is, when they click tweet, it just reloads the twitter box, empty. I want it to load something new, like a "thank you, now fill in this email form" and show a mailchimp form. Ok so this is the @anywhere code currently working fine: <div id="tbox"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#tbox").tweetBox({ height: 100, width: 400, defaultContent: " #vocabbomb", label: "Use the word foo in a tweet:", }); }); </script> So this is fine, and when the user writes a tweet, it just re-displays the twitter box. I understand there is a function that lets you specify stuff after the tweet is made: (example from http://dev.twitter.com/pages/anywhere_tweetbox) <div id="example-ontweet"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#example-ontweet").tweetBox({ onTweet : function(plaintext, html) { console.log(plaintext); alert(html); } }); }); </script> Is this the best way to attempt this? Or do I need a function or something that changes what's in the div to something else? I want the mailchimp email form to show up after the tweet. It includes a ton of script and tags and starts like this: <!-- Begin MailChimp Signup Form --> <!--[if IE]> <style type="text/css" media="screen"> #mc_embed_signup fieldset {position: relative;} #mc_embed_signup legend {position: absolute; top: -1em; left: .2em;} </style> <![endif]--> <!--[if IE 7]> <style type="text/css" media="screen"> .mc-field-group {overflow:visible;} </style> <![endif]--> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script> <script type="text/javascript" src="http://downloads.mailchimp.com/js/jquery.validate.js"></script> <script type="text/javascript" src="http://downloads.mailchimp.com/js/jquery.form.js"></script> <div id="mc_embed_signup"> <form action="http://faresharenyc.us1.list-manage.com/subscribe/post?u=106b58b4751a007d826715754&amp;id=2fe6ba4e6a" method="post" id="mc-embedded-subscribe-form" name="mc-embedded-subscribe-form" class="validate" target="_blank" style="font: normal 100% Arial, sans-serif;font-size: 10px;"> ... So my attempt to just require it inside the function didn't work at all: <div id="tbox"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#tbox").tweetBox({ height: 100, width: 400, defaultContent: " #vocabbomb", label: "Use the word foo in a tweet:", onTweet: function(plain, html){ <?php require_once('mailchimp.html'); ?> } }); }); </script> Nettuts had a brief discussion here: http://net.tutsplus.com/tutorials/javascript-ajax/using-twitters-anywhere-service-in-6-steps/ I am seeing now that the 'onTweet' function simply adds some text above the twitter box, but doesn't actually replace the entire twitter box. How do I do that? Is it possible? Thanks!

• Create / build / generate a web form that can be on my server and has modern looks and could be impl

  - by Luay

  I have a small web site and would like to add a 'contact us' form and a 'feedback' form. i would like the forms to satisfy the following: 1- be modern looking (with beautiful css effects) 2- the form fields are validated properly and 'inline'. What I mean is once a user skips a required field or enters an email address incorrectly some kind of tooltip or icon is displayed to ask him to cerrect the error (as opposed to a message box that appears after the user clicks 'submit') 3- once the submit button is clicked the form contents are emailed to me. 4- the whole thing can be setup by a noob like myself. 5- no ads on the form I have been searching for at least 5 days for a solution but I can't seem to find anything the would satisfy the above 5 conditions. I don't mind paying for a solution as long as it is hosted on my site and it is a one off payment and not a monthly payment. So far my search has lead me to the following: 1 wufoo. The good: the generated forms seem to look okay but not the best there is. The bad: the free service is limited to 100 submissions. ads on the form. it is not hosted on my server. Paid service requires monthly payments 2- emailmeform: almost same as above except the generated form looks old. They do have an offer where you pay only $4 to get the form and set it up on your own site but that doesn't solve the fact that the forms look old. 3- formAssembly: same as above with minor variations (the generated form looks better) 4- formchamp, formthis, kontaktr,... And other similar online services: the same problem. either the form generated looks outdated or require monthly payments or they put ads...they don't satisfy my conditions. 5- coffeecup form builder. a desktop software. The problem is the generated forms look too old and use flash. 6- simfatic. Another software. Much better than coffeecup. almost satisfies my conditions but the forms not as good as I like. 7- many, many php scripts or html templates that look so outdated or fail when tested (probably because they are too old). Seriously guys, how hard is this. At least 90%+ of website contain at least a 'contact us' form. Why aren't there better solutions? if there is I can't seem to find them. In terms of looks I want something similar to this: http://web-kreation.com/articles/lightform-free-ajaxphp-contact-form/ It is called lightform. And this is a perfect example of what I mean by 'inline' validation. the only problem: there is no script to handle sending the mail. Even if I find one, I don't know how to modify it for my needs. So could you please help me out. I really can't search anymore. I reached rock bottom with this issue. I need a complete solution. If nothing exists then at least a: 1- form template (html) that looks nice and can easily be modified 2- a validation script that does 'inline' validation like the example above (or similar to it) and can be easily implemented by a noob like me to work with the html form. 3- a php script that will handle sending the email and can be easily implemented (all three working in harmony). I hope there is a complete solution but am I asking for too much? Pretty please...help...

• jQuery Validation in ASP.NET

  - by Abu Hamzah

  i have a strange situation may its a easy fix or something i may be missing but here is the question. i have a asp.net form with master page and my validation works great without any problem but the problems starts when i try to hook my click event to the server side, here is what i meant: i have a form with few fields on it and if the form is empty than it should STOP submitting, otherwise allow me to execute the server side script but its not happening, even my form is in invalid state (i do get error message saying i have to enter the required fileds) but still executing my server side script. i would like to execute my server side script only if the form is in valid state. here is my code: my master page <%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>jQuery Validation in ASP.NET Master Page</title> <script src="Scripts/jquery-1.3.2.js" type="text/javascript"></script> <script src="Scripts/jquery-1.3.2-vsdoc2.js" type="text/javascript"></script> <script src="Scripts/jquery.validate.js" type="text/javascript"></script> <asp:ContentPlaceHolder id="head" runat="server"> </asp:ContentPlaceHolder> </head> <body> <form id="form1" runat="server"> <div> <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> </div> </form> </body> </html> my content page: <%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"> <script type="text/javascript"> $(document).ready(function() { $("#aspnetForm").validate({ rules: { <%=txtName.UniqueID %>: { minlength: 2, required: true }, <%=txtEmail.UniqueID %>: { required: true, email:true } }, messages: { <%=txtName.UniqueID %>:{ required: "* Required Field *", minlength: "* Please enter atleast 2 characters *" } } }); }); </script> Name: <asp:TextBox ID="txtName" MaxLength="30" runat="server" /><br /> Email: <asp:TextBox ID="txtEmail" runat="server"></asp:TextBox><br /> <asp:Button ID="btnSubmit" runat="server" onclick="SubmitTheForm();" Text="Submit" /> </asp:Content> function SubmitTheForm() { SaveTheForm(); } function SaveTheForm() { debugger; var request = buildNewContactRequest(); ContactServiceProxy.invoke({ serviceMethod: "PostNewContact", data: { request: request }, callback: function(response) { processCompletedContactStore(response); }, error: function(xhr, errorMsg, thrown) { postErrorAndUnBlockUI(xhr, errorMsg, thrown); } }); return false; }

• Output a php multi-dimensional array to a html table

  - by Fireflight

  I have been banging my head against the wall with this one for nearly a week now, and am no closer than I was the first day. I have a form that has 8 columns and a variable number of rows which I need to email to the client in a nicely formatted email. The form submits the needed fields as a multidimensional array. Rough example is below: <input name="order[0][topdiameter]" type="text" id="topdiameter0" value="1" size="5" /> <input name="order[0][bottomdiameter]" type="text" id="bottomdiameter0" value="1" size="5" /> <input name="order[0][slantheight]" type="text" id="slantheight0" value="1" size="5" /> <select name="order[0][fittertype]" id="fittertype0"> <option value="harp">Harp</option> <option value="euro">Euro</option> <option value="bulbclip">Regular</option> </select> <input name="order[0][washerdrop]" type="text" id="washerdrop0" value="1" size="5" /> <select name="order[0][fabrictype]" id="fabrictype"> <option value="linen">Linen</option> <option value="pleated">Pleated</option> </select> <select name="order[0][colours]" id="colours0"> <option value="beige">Beige</option> <option value="white">White</option> <option value="eggshell">Eggshell</option> <option value="parchment">Parchment</option> </select> <input name="order[0][quantity]" type="text" id="quantity0" value="1" size="5" /> This form is formatted in a table, and rows can be added to it dynamically. What I've been unable to do is get a properly formatted table out of the array. This is what I'm using now (grabbed from the net). <?php if (isset($_POST["submit"])) { $arr= $_POST['order'] echo '<table>'; foreach($arr as $arrs) { echo '<tr>'; foreach($arrs as $item) { echo "<td>$item</td>"; } echo '</tr>'; } echo '</table>; }; ?> This works perfectly for a single row of data. If I try submitting 2 or more rows from the form then one of the columns disappears. I'd like the table to be formatted as: | top | Bottom | Slant | Fitter | Washer | Fabric | Colours | Quantity | ------------------------------------------------------------------------ |value| value | value | value | value | value | value | value | with additional rows as needed. But, I can't find any examples that will generate that type of table! It seems like this should be something fairly straightforward, but I just can't locate an example that works the way I need it too.

• Create and Share a File (Also a mysterious error)

  - by Kirk

  My goal is to create a XML file and then send it through the share Intent. I'm able to create a XML file using this code FileOutputStream outputStream = context.openFileOutput(fileName, Context.MODE_WORLD_READABLE); PrintStream printStream = new PrintStream(outputStream); String xml = this.writeXml(); // get XML here printStream.println(xml); printStream.close(); I'm stuck trying to retrieve a Uri to the output file in order to share it. I first tried to access the file by converting the file to a Uri File outFile = context.getFileStreamPath(fileName); return Uri.fromFile(outFile); This returns file:///data/data/com.my.package/files/myfile.xml but I cannot appear to attach this to an email, upload, etc. If I manually check the file length, it's proper and shows there is a reasonable file size. Next I created a content provider and tried to reference the file and it isn't a valid handle to the file. The ContentProvider doesn't ever seem to be called a any point. Uri uri = Uri.parse("content://" + CachedFileProvider.AUTHORITY + "/" + fileName); return uri; This returns content://com.my.package.provider/myfile.xml but I check the file and it's zero length. How do I access files properly? Do I need to create the file with the content provider? If so, how? Update Here is the code I'm using to share. If I select Gmail, it does show as an attachment but when I send it gives an error Couldn't show attachment and the email that arrives has no attachment. public void onClick(View view) { Log.d(TAG, "onClick " + view.getId()); switch (view.getId()) { case R.id.share_cancel: setResult(RESULT_CANCELED, getIntent()); finish(); break; case R.id.share_share: MyXml xml = new MyXml(); Uri uri; try { uri = xml.writeXmlToFile(getApplicationContext(), "myfile.xml"); //uri is "file:///data/data/com.my.package/files/myfile.xml" Log.d(TAG, "Share URI: " + uri.toString() + " path: " + uri.getPath()); File f = new File(uri.getPath()); Log.d(TAG, "File length: " + f.length()); // shows a valid file size Intent shareIntent = new Intent(); shareIntent.setAction(Intent.ACTION_SEND); shareIntent.putExtra(Intent.EXTRA_STREAM, uri); shareIntent.setType("text/plain"); startActivity(Intent.createChooser(shareIntent, "Share")); } catch (FileNotFoundException e) { e.printStackTrace(); } break; } } I noticed that there is an Exception thrown here from inside createChooser(...), but I can't figure out why it's thrown. E/ActivityThread(572): Activity com.android.internal.app.ChooserActivity has leaked IntentReceiver com.android.internal.app.ResolverActivity$1@4148d658 that was originally registered here. Are you missing a call to unregisterReceiver()? I've researched this error and can't find anything obvious. Both of these links suggest that I need to unregister a receiver. Chooser Activity Leak - Android Why does Intent.createChooser() need a BroadcastReceiver and how to implement? I have a receiver setup, but it's for an AlarmManager that is set elsewhere and doesn't require the app to register / unregister. Code for openFile(...) In case it's needed, here is the content provider I've created. public ParcelFileDescriptor openFile(Uri uri, String mode) throws FileNotFoundException { String fileLocation = getContext().getCacheDir() + "/" + uri.getLastPathSegment(); ParcelFileDescriptor pfd = ParcelFileDescriptor.open(new File(fileLocation), ParcelFileDescriptor.MODE_READ_ONLY); return pfd; }

• Tablesorter - filter inside input fields and values

  - by Zeracoke

  I have a small quest to accomplish, and I reached a point when nothing works... So the problem is. I have a paged table with a lot of input fields inside the rows with values, and I would like to search inside these values. Let me Show this, I hope that somebody will got the idea what I should do... <script type="text/javascript"> // add parser through the tablesorter addParser method $.tablesorter.addParser({ id: 'inputs', is: function(s) { return false; }, format: function(s, table, cell, cellIndex) { var $c = $(cell); // return 1 for true, 2 for false, so true sorts before false if (!$c.hasClass('updateInput')) { $c .addClass('updateInput') .bind('keyup', function() { $(table).trigger('updateCell', [cell, false]); // false to prevent resort }); } return $c.find('input').val(); }, type: 'text' }); $(function() { $('table').tablesorter({ widgets: ['zebra', 'stickyHeaders', 'resizable', 'filter'], widgetOptions: { stickyHeaders : '', // number or jquery selector targeting the position:fixed element stickyHeaders_offset : 110, // added to table ID, if it exists stickyHeaders_cloneId : '-sticky', // trigger "resize" event on headers stickyHeaders_addResizeEvent : true, // if false and a caption exist, it won't be included in the sticky header stickyHeaders_includeCaption : true, // The zIndex of the stickyHeaders, allows the user to adjust this to their needs stickyHeaders_zIndex : 2, // jQuery selector or object to attach sticky header to stickyHeaders_attachTo : null, // scroll table top into view after filtering stickyHeaders_filteredToTop: true, resizable: true, filter_onlyAvail : 'filter-onlyAvail', filter_childRows : true, filter_startsWith : true, filter_useParsedData : true, filter_defaultAttrib : 'data-value' }, headers: { 1: {sorter: 'inputs', width: '50px'}, 2: {sorter: 'inputs'}, 3: {sorter: 'inputs'}, 4: {sorter: 'inputs'}, 5: {sorter: 'inputs'}, 6: {sorter: 'inputs'}, 7: {sorter: 'inputs', width: '100px'}, 8: {sorter: 'inputs', width: '140px'}, 9: {sorter: 'inputs'}, 10: {sorter: 'inputs'}, 11: {sorter: 'inputs'}, } }); $('table').tablesorterPager({container: $(".pager"), positionFixed: false, size: 50, pageDisplay : $(".pagedisplay"), pageSize : $(".pagesize"), }); $("#table1").tablesorter(options); /* make second table scroll within its wrapper */ options.widgetOptions.stickyHeaders_attachTo = '.wrapper'; // or $('.wrapper') $("#table2").tablesorter(options); }); </script> The structure of the tables: <tr class="odd" style="display: table-row;"> <form action="/self.php" method="POST"> </form><input type="hidden" name="f" value="data"> <td><input type="hidden" name="mod_id" value="741">741</td> <td class="updateInput"><input type="text" name="name" value="Test User Name"></td> <td class="updateInput"><input type="text" name="address" value="2548451 Random address"></td> <td class="updateInput"><input type="email" name="email" value=""></td> <td class="updateInput"><input type="text" name="entitlement" value="none"></td> <td class="updateInput"><input type="text" name="card_number" value="6846416548644352"></td> <td class="updateInput"><input type="checkbox" name="verify" value="1" checked=""></td> <td class="updateInput"><input type="checkbox" name="card_sended" value="1" checked=""></td> <td class="updateInput"><input type="text" name="create_date" value="2014-02-12 21:09:16"></td> <td class="updateInput"><a href="self.php?f=data&amp;del=741">X</a></td> <td class="updateInput"><input type="submit" value="SAVE"></td><td class="updateInput"></td></tr> So the thing is I don't know how to configure the filter to search these values... I already added some options, but none of them are working... Any help would be great!

• How do I make java wait for boolean to run funciton

  - by TWeeKeD

  I'm sure this is pretty simple but I can't figure out and it sucks I'm up on suck on (what should be) an easy step. ok. I have a method that runs one function that give a response. this method actually handles the uploading of the file so o it takes a second to give a response. I need this response in the following method. sendPicMsg needs to complete and then forward it's response to sendMessage. Please help. b1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if(!uploadMsgPic.equalsIgnoreCase("")){ Log.v("response","Pic in storage"); sendPicMsg(); sendMessage(); }else{ sendMessage(); } 1st Method public void sendPicMsg(){ Log.v("response", "sendPicMsg Loaded"); if(!uploadMsgPic.equalsIgnoreCase("")){ final SharedPreferences preferences = this.getActivity().getSharedPreferences("MyPreferences", getActivity().MODE_PRIVATE); AsyncHttpClient client3 = new AsyncHttpClient(); RequestParams params3 = new RequestParams(); File file = new File(uploadMsgPic); try { File f = new File(uploadMsgPic.replace(".", "1.")); f.createNewFile(); //Convert bitmap to byte array Bitmap bitmap = decodeFile(file,400); ByteArrayOutputStream bos = new ByteArrayOutputStream(); bitmap.compress(CompressFormat.PNG, 0 /*ignored for PNG*/, bos); byte[] bitmapdata = bos.toByteArray(); //write the bytes in file FileOutputStream fos = new FileOutputStream(f); fos.write(bitmapdata); params3.put("file", f); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } params3.put("email", preferences.getString("loggedin_user", "")); params3.put("webversion", "1"); client3.post("http://peekatu.com/apiweb/msgPic_upload.php",params3, new AsyncHttpResponseHandler() { @Override public void onSuccess(String response) { Log.v("response", "Upload Complete"); refreshChat(); //responseString = response; Log.v("response","msgPic has been uploaded"+response); //parseChatMessages(response); response=picurl; uploadMsgPic = ""; if(picurl!=null){ Log.v("response","picurl is set"); } if(picurl==null){ Log.v("response", "picurl no ready"); }; } }); sendMessage(); } } 2nd Method public void sendMessage(){ final SharedPreferences preferences = this.getActivity().getSharedPreferences("MyPreferences", getActivity().MODE_PRIVATE); if(preferences.getString("Username", "").length()<=0){ editText1.setText(""); Toast.makeText(this.getActivity(), "Please Login to send messages.", 2); return; } AsyncHttpClient client = new AsyncHttpClient(); RequestParams params = new RequestParams(); if(type.equalsIgnoreCase("3")){ params.put("toid",user); params.put("action", "sendprivate"); }else{ params.put("room", preferences.getString("selected_room", "Adult Lobby")); params.put("action", "insert"); } Log.v("response", "Sending message "+editText1.getText().toString()); params.put("message",editText1.getText().toString() ); params.put("media", picurl); params.put("email", preferences.getString("loggedin_user", "")); params.put("webversion", "1"); client.post("http://peekatu.com/apiweb/messagetest.php",params, new AsyncHttpResponseHandler() { @Override public void onSuccess(String response) { refreshChat(); //responseString = response; Log.v("response", response); //parseChatMessages(response); if(picurl!=null) Log.v("response", picurl); } }); editText1.setText(""); lv.setSelection(adapter.getCount() - 1); }

• Linux router: ping doesn't route back

  - by El Barto

  I have a Debian box which I'm trying to set up as a router and an Ubuntu box which I'm using as a client. My problem is that when the Ubuntu client tries to ping a server on the Internet, all the packets are lost (though, as you can see below, they seem to go to the server and back without problem). I'm doing this in the Ubuntu Box: # ping -I eth1 my.remote-server.com PING my.remote-server.com (X.X.X.X) from 10.1.1.12 eth1: 56(84) bytes of data. ^C --- my.remote-server.com ping statistics --- 13 packets transmitted, 0 received, 100% packet loss, time 12094ms (I changed the name and IP of the remote server for privacy). From the Debian Router I see this: # tcpdump -i eth1 -qtln icmp tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes IP X.X.X.X > 10.1.1.12: ICMP echo reply, id 305, seq 7, length 64 IP 10.1.1.12 > X.X.X.X: ICMP echo request, id 305, seq 8, length 64 IP X.X.X.X > 10.1.1.12: ICMP echo reply, id 305, seq 8, length 64 IP 10.1.1.12 > X.X.X.X: ICMP echo request, id 305, seq 9, length 64 IP X.X.X.X > 10.1.1.12: ICMP echo reply, id 305, seq 9, length 64 IP 10.1.1.12 > X.X.X.X: ICMP echo request, id 305, seq 10, length 64 IP X.X.X.X > 10.1.1.12: ICMP echo reply, id 305, seq 10, length 64 IP 10.1.1.12 > X.X.X.X: ICMP echo request, id 305, seq 11, length 64 IP X.X.X.X > 10.1.1.12: ICMP echo reply, id 305, seq 11, length 64 ^C 9 packets captured 9 packets received by filter 0 packets dropped by kernel # tcpdump -i eth2 -qtln icmp tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth2, link-type EN10MB (Ethernet), capture size 65535 bytes IP 192.168.1.10 > X.X.X.X: ICMP echo request, id 360, seq 213, length 64 IP X.X.X.X > 192.168.1.10: ICMP echo reply, id 360, seq 213, length 64 IP 192.168.1.10 > X.X.X.X: ICMP echo request, id 360, seq 214, length 64 IP X.X.X.X > 192.168.1.10: ICMP echo reply, id 360, seq 214, length 64 IP 192.168.1.10 > X.X.X.X: ICMP echo request, id 360, seq 215, length 64 IP X.X.X.X > 192.168.1.10: ICMP echo reply, id 360, seq 215, length 64 IP 192.168.1.10 > X.X.X.X: ICMP echo request, id 360, seq 216, length 64 IP X.X.X.X > 192.168.1.10: ICMP echo reply, id 360, seq 216, length 64 IP 192.168.1.10 > X.X.X.X: ICMP echo request, id 360, seq 217, length 64 IP X.X.X.X > 192.168.1.10: ICMP echo reply, id 360, seq 217, length 64 ^C 10 packets captured 10 packets received by filter 0 packets dropped by kernel And at the remote server I see this: # tcpdump -i eth0 -qtln icmp tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 1, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 1, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 2, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 2, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 3, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 3, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 4, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 4, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 5, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 5, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 6, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 6, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 7, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 7, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 8, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 8, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 9, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 9, length 64 18 packets captured 228 packets received by filter 92 packets dropped by kernel Here "X.X.X.X" is my remote server's IP and "Y.Y.Y.Y" is my local network's public IP. So, what I understand is that the ping packets are coming out of the Ubuntu box (10.1.1.12), to the router (10.1.1.1), from there to the next router (192.168.1.1) and reaching the remote server (X.X.X.X). Then they come back all the way to the Debian router, but they never reach the Ubuntu box back. What am I missing? Here's the Debian router setup: # ifconfig eth1 Link encap:Ethernet HWaddr 94:0c:6d:82:0d:98 inet addr:10.1.1.1 Bcast:10.1.1.255 Mask:255.255.255.0 inet6 addr: fe80::960c:6dff:fe82:d98/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:105761 errors:0 dropped:0 overruns:0 frame:0 TX packets:48944 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:40298768 (38.4 MiB) TX bytes:44831595 (42.7 MiB) Interrupt:19 Base address:0x6000 eth2 Link encap:Ethernet HWaddr 6c:f0:49:a4:47:38 inet addr:192.168.1.10 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::6ef0:49ff:fea4:4738/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:38335992 errors:0 dropped:0 overruns:0 frame:0 TX packets:37097705 errors:0 dropped:0 overruns:0 carrier:1 collisions:0 txqueuelen:1000 RX bytes:4260680226 (3.9 GiB) TX bytes:3759806551 (3.5 GiB) Interrupt:27 eth3 Link encap:Ethernet HWaddr 94:0c:6d:82:c8:72 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:20 Base address:0x2000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:3408 errors:0 dropped:0 overruns:0 frame:0 TX packets:3408 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:358445 (350.0 KiB) TX bytes:358445 (350.0 KiB) tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:10.8.0.1 P-t-P:10.8.0.2 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:2767779 errors:0 dropped:0 overruns:0 frame:0 TX packets:1569477 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:3609469393 (3.3 GiB) TX bytes:96113978 (91.6 MiB) #

• Removing the XML Formatter from ASP.NET Web API Applications

  - by Rick Strahl

  ASP.NET Web API's default output format is supposed to be JSON, but when I access my Web APIs using the browser address bar I'm always seeing an XML result instead. When working on AJAX application I like to test many of my AJAX APIs with the browser while working on them. While I can't debug all requests this way, GET requests are easy to test in the browser especially if you have JSON viewing options set up in your various browsers. If I preview a Web API request in most browsers I get an XML response like this: Why is that? Web API checks the HTTP Accept headers of a request to determine what type of output it should return by looking for content typed that it has formatters registered for. This automatic negotiation is one of the great features of Web API because it makes it easy and transparent to request different kinds of output from the server. In the case of browsers it turns out that most send Accept headers that look like this (Chrome in this case): Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Web API inspects the entire list of headers from left to right (plus the quality/priority flag q=) and tries to find a media type that matches its list of supported media types in the list of formatters registered. In this case it matches application/xml to the Xml formatter and so that's what gets returned and displayed. To verify that Web API indeed defaults to JSON output by default you can open the request in Fiddler and pop it into the Request Composer, remove the application/xml header and see that the output returned comes back in JSON instead. An accept header like this: Accept: text/html,application/xhtml+xml,*/*;q=0.9 or leaving the Accept header out altogether should give you a JSON response. Interestingly enough Internet Explorer 9 also displays JSON because it doesn't include an application/xml Accept header: Accept: text/html, application/xhtml+xml, */* which for once actually seems more sensible. Removing the XML Formatter We can't easily change the browser Accept headers (actually you can by delving into the config but it's a bit of a hassle), so can we change the behavior on the server? When working on AJAX applications I tend to not be interested in XML results and I always want to see JSON results at least during development. Web API uses a collection of formatters and you can go through this list and remove the ones you don't want to use - in this case the XmlMediaTypeFormatter. To do this you can work with the HttpConfiguration object and the static GlobalConfiguration object used to configure it: protected void Application_Start(object sender, EventArgs e) { // Action based routing (used for RPC calls) RouteTable.Routes.MapHttpRoute( name: "StockApi", routeTemplate: "stocks/{action}/{symbol}", defaults: new { symbol = RouteParameter.Optional, controller = "StockApi" } ); // WebApi Configuration to hook up formatters and message handlers RegisterApis(GlobalConfiguration.Configuration); } public static void RegisterApis(HttpConfiguration config) { // remove default Xml handler var matches = config.Formatters .Where(f = f.SupportedMediaTypes .Where(m = m.MediaType.ToString() == "application/xml" || m.MediaType.ToString() == "text/xml") .Count() 0) .ToList() ; foreach (var match in matches) config.Formatters.Remove(match); } } That LINQ code is quite a mouthful of nested collections, but it does the trick to remove the formatter based on the content type. You can also look for the specific formatter (XmlMediatTypeFormatter) by its type name which is simpler, but it's better to search for the supported types as this will work even if there are other custom formatters added. Once removed, now the browser request results in a JSON response: It's a simple solution to a small debugging task that's made my life easier.

• The Mysterious ARR Server Farm to URL Rewrite link

  - by OWScott

  Application Request Routing (ARR) is a reverse proxy plug-in for IIS7+ that does many things, including functioning as a load balancer.  For this post, I’m assuming that you already have an understanding of ARR.  Today I wanted to find out how the mysterious link between ARR and URL Rewrite is maintained.  Let me explain… ARR is unique in that it doesn’t work by itself.  It sits on top of IIS7 and uses URL Rewrite.  As a result, ARR depends on URL Rewrite to ‘catch’ the traffic and redirect it to an ARR Server Farm. As the last step of creating a new Server Farm, ARR will prompt you with the following: If you accept the prompt, it will create a URL Rewrite rule for you.  If you say ‘No’, then you’re on your own to create a URL Rewrite rule. When you say ‘Yes’, the Server Farm’s checkbox for “Use URL Rewrite to inspect incoming requests” will be checked.  See the following screenshot. However, I’m not a fan of this auto-rule.  The problem is that if I make any changes to the URL Rewrite rule, which I always do, and then make the wrong change in ARR, it will blow away my settings.  So, I prefer to create my own rule and manage it myself. Since I had some old rules that were managed by ARR, I wanted to update them so that they were no longer managed that way.  I took a look at a config in applicationHost.config to try to find out what property would bind the two together.  I assumed that there would be a property on the ServerFarm called something like urlRewriteRuleName that would serve as the link between ARR and URL Rewrite.  I found no such property.  After a bit of testing, I found that the name of the URL Rewrite rule is the only link between ARR and URL Rewrite.  I wouldn’t have guessed.  The URL Rewrite rule needs to be exactly ARR_{ServerFarm Name}_loadBalance, although it’s not case sensitive. Consider the following auto-created URL Rewrite rule: And, the link between ARR and URL Rewrite exists: Now, as soon as I rename that to anything else, for example, site.com ARR Binding, the link between ARR and URL Rewrite is broken. To be certain of the relationship, I renamed it back again and sure enough, the relationship was reestablished. Why is this important?  It’s only important if you want to decouple the relationship between ARR the URL Rewrite rule, but if you want to do so, the best way to do that is to rename the URL Rewrite rule.  If you uncheck the “Use URL Rewrite to inspect incoming requests” checkbox, it will delete your rule for you without prompting.  Conclusion The mysterious link between ARR and URL Rewrite only exists through the ARR Rule name.  If you want to break the link, simply rename the URL Rewrite rule.  It’s completely safe to do so, and, in my opinion, this is a rule that you should manage yourself anyway.

• What I don&rsquo;t like about WIF&rsquo;s Claims-based Authorization

  - by Your DisplayName here!

  In my last post I wrote about what I like about WIF’s proposed approach to authorization – I also said that I definitely would build upon that infrastructure for my own systems. But implementing such a system is a little harder as it could be. Here’s why (and that’s purely my perspective): First of all WIF’s authorization comes in two “modes” Per-request authorization. When an ASP.NET/WCF request comes in, the registered authorization manager gets called. For SOAP the SOAP action gets passed in. For HTTP requests (ASP.NET, WCF REST) the URL and verb. Imperative authorization This happens when you explicitly call the claims authorization API from within your code. There you have full control over the values for action and resource. In ASP.NET per-request authorization is optional (depends on if you have added the ClaimsAuthorizationHttpModule). In WCF you always get the per-request checks as soon as you register the authorization manager in configuration. I personally prefer the imperative authorization because first of all I don’t believe in URL based authorization. Especially in the times of MVC and routing tables, URLs can be easily changed – but then you also have to adjust your authorization logic every time. Also – you typically need more knowledge than a simple “if user x is allowed to invoke operation x”. One problem I have is, both the per-request calls as well as the standard WIF imperative authorization APIs wrap actions and resources in the same claim type. This makes it hard to distinguish between the two authorization modes in your authorization manager. But you typically need that feature to structure your authorization policy evaluation in a clean way. The second problem (which is somehow related to the first one) is the standard API for interacting with the claims authorization manager. The API comes as an attribute (ClaimsPrincipalPermissionAttribute) as well as a class to use programmatically (ClaimsPrincipalPermission). Both only allow to pass in simple strings (which results in the wrapping with standard claim types mentioned earlier). Both throw a SecurityException when the check fails. The attribute is a code access permission attribute (like PrincipalPermission). That means it will always be invoked regardless how you call the code. This may be exactly what you want, or not. In a unit testing situation (like an MVC controller) you typically want to test the logic in the function – not the security check. The good news is, the WIF API is flexible enough that you can build your own infrastructure around their core. For my own projects I implemented the following extensions: A way to invoke the registered claims authorization manager with more overloads, e.g. with different claim types or a complete AuthorizationContext. A new CAS attribute (with the same calling semantics as the built-in one) with custom claim types. A MVC authorization attribute with custom claim types. A way to use branching – as opposed to catching a SecurityException. I will post the code for these various extensions here – so stay tuned.

• ASP.NET Web API - Screencast series with downloadable sample code - Part 1

  - by Jon Galloway

  There's a lot of great ASP.NET Web API content on the ASP.NET website at http://asp.net/web-api. I mentioned my screencast series in original announcement post, but we've since added the sample code so I thought it was worth pointing the series out specifically. This is an introductory screencast series that walks through from File / New Project to some more advanced scenarios like Custom Validation and Authorization. The screencast videos are all short (3-5 minutes) and the sample code for the series is both available for download and browsable online. I did the screencasts, but the samples were written by the ASP.NET Web API team. So - let's watch them together! Grab some popcorn and pay attention, because these are short. After each video, I'll talk about what I thought was important. I'm embedding the videos using HTML5 (MP4) with Silverlight fallback, but if something goes wrong or your browser / device / whatever doesn't support them, I'll include the link to where the videos are more professionally hosted on the ASP.NET site. Note also if you're following along with the samples that, since Part 1 just looks at the File / New Project step, the screencast part numbers are one ahead of the sample part numbers - so screencast 4 matches with sample code demo 3. Note: I started this as one long post for all 6 parts, but as it grew over 2000 words I figured it'd be better to break it up. Part 1: Your First Web API [Video and code on the ASP.NET site] This screencast starts with an overview of why you'd want to use ASP.NET Web API: Reach more clients (thinking beyond the browser to mobile clients, other applications, etc.) Scale (who doesn't love the cloud?!) Embrace HTTP (a focus on HTTP both on client and server really simplifies and focuses service interactions) Next, I start a new ASP.NET Web API application and show some of the basics of the ApiController. We don't write any new code in this first step, just look at the example controller that's created by File / New Project. using System; using System.Collections.Generic; using System.Linq; using System.Net.Http; using System.Web.Http; namespace NewProject_Mvc4BetaWebApi.Controllers { public class ValuesController : ApiController { // GET /api/values public IEnumerable<string> Get() { return new string[] { "value1", "value2" }; } // GET /api/values/5 public string Get(int id) { return "value"; } // POST /api/values public void Post(string value) { } // PUT /api/values/5 public void Put(int id, string value) { } // DELETE /api/values/5 public void Delete(int id) { } } } Finally, we walk through testing the output of this API controller using browser tools. There are several ways you can test API output, including Fiddler (as described by Scott Hanselman in this post) and built-in developer tools available in all modern browsers. For simplicity I used Internet Explorer 9 F12 developer tools, but you're of course welcome to use whatever you'd like. A few important things to note: This class derives from an ApiController base class, not the standard ASP.NET MVC Controller base class. They're similar in places where API's and HTML returning controller uses are similar, and different where API and HTML use differ. A good example of where those things are different is in the routing conventions. In an HTTP controller, there's no need for an "action" to be specified, since the HTTP verbs are the actions. We don't need to do anything to map verbs to actions; when a request comes in to /api/values/5 with the DELETE HTTP verb, it'll automatically be handled by the Delete method in an ApiController. The comments above the API methods show sample URL's and HTTP verbs, so we can test out the first two GET methods by browsing to the site in IE9, hitting F12 to bring up the tools, and entering /api/values in the URL: That sample action returns a list of values. To get just one value back, we'd browse to /values/5: That's it for Part 1. In Part 2 we'll look at getting data (beyond hardcoded strings) and start building out a sample application.

• POP Forums v9 Beta 1 for ASP.NET MVC 3 posted to CodePlex!

  - by Jeff

  As promised, I posted a beta build of my forum app for ASP.NET MVC 3. Get the new goodies here: http://popforums.codeplex.com/releases/view/58228 This is the first beta for the ASP.NET MVC 3 version of POP Forums. It is nearly feature complete, and ready for testing and feedback. For previous release notes, look here, here and here.Check out the live preview: http://preview.popforums.com/ForumsSetup instructions are on the home page of this project. The new hotness in the beta, or what has been done since the last preview: All views converted to use Razor E-mail subscription/notification of new posts New post indicators/mark read buttons Permalinks to posts Jump to newest post (from new post indicators) Recent topics Favorite topics Moderator functions for topics (pin/close/delete, plus move and rename) Search, ported from v8. Not a ton of optimization here, or new unit testing, but the old version worked pretty well User posts (topics the user posted in) Forgot password Vanity items (signatures and avatars) Hide vanity items per user preference Some minor data caching where appropriate A little bit of UI refinement Lots-o-bug fixes Lots-o-unit tests What's next? The plan between now and the next beta is as follows: Continue working through features/tasks, and fix bugs as they're reported Integrate the forum into a real, production site Refine the UI Refactor as much as possible... the code organization is not entirely logical in some places After the second beta, a release candidate will follow, with a real "final" release after that. Subsequent releases should come relatively frequently and without a lot of risk. The trick in building this thing has been that it mostly tossed the previous WebForms version, which was all full of crusties. The time table for this is a little harder to pin down, as day jobs and families will have their effect. Other notes Refactoring will be a priority. As the features of MVC have evolved, so have my desires to use it in a fashion that makes things clear and easy to follow. I don't even know if anyone will ever start mucking around in the code, but on the off chance they do, I'd like what they find to not suck. Other nice-to-haves are builds to target Windows Azure and SQL CE. A nice setup UI would be super too. I think the ASP.NET MVC world has gone long enough without a decent forum.The biggest challenge that I've found is making the forum something that can be dropped in any app. While it does rope its views into an area, areas are mostly just routing details. I haven't thought of a clever way yet to limit dependency injection, for example, to just the forum bits. I mean, everyone should be using Ninject, but how realistic is that? ;)How much time and effort should you spend on POP Forums in its current state? Change is inevitable, but at this point I'm reasonably committed to not changing the database schema. I really think it will stay as-is. All bets are off for the various interfaces throughout the app, but the data should generally resist change. It's not even that different from v8, which was one of the original goals because I didn't want to rewrite SQL or introduce a new ORM or whatever. My point is that if you wanted to build a site around this today, even though it's not entirely functional, I think it's low risk in terms of data loss. I can't vouch for whether or not you know what you're doing.I've been having some chats with people lately about quoting posts, and honestly there has to be something better and straight forward. That continues to be a holy grail of mine, and some day, I hope to find it.Enjoy... it's starting to feel more real every day!
