• New line (in the code) after <li> element breaking layout

  - by BT643

  Weirdly, I've never come across this issue before, but I've just started making a site and the top navigation isn't playing nicely. I want a small amount of white space between each menu item, but when I have new lines between my <li> elements and my <a> elements in my IDE (Netbeans), the white space disappears, yet it looks fine if I have <li><a></a></li> all on the same line. I was always under the impression html ignored white space in the code. I've checked for any weird characters causing problems in other text editors and can't find anything. Here's the code... Like this the menu looks correct but code looks ugly (I know it looks fine when it's this simple, but I'm going be adding more complexity in which makes it look awful all on one line): <ul id="menu"> <li><a href="#">About</a></li> <li class="active"><a href="<?php echo site_url("tracklist"); ?>">Track List</a></li> <li><a href="<?php echo site_url("stats"); ?>">Stats</a></li> <li><a href="#">Stats</a></li> </ul> Like this the menu looks wrong but code looks fine: <ul id="menu"> <li> <a href="#">About</a> </li> <li class="active"> <a href="<?php echo site_url("tracklist"); ?>">Track List</a> </li> <li> <a href="<?php echo site_url("stats"); ?>">Stats</a> </li> <li> <a href="#">Stats</a> </li> </ul> Here's the css: #menu { float: right; } #menu li { display: inline-block; padding: 5px; background-color: #932996; border-bottom: solid 1px #932996; } #menu li:hover { border-bottom: solid 3px #FF0000; } #menu li.active { background-color: #58065e; } I'm sure it's something simple I'm doing wrong... but can someone shed some light on this for me? Sorry for the lengthy post (my first on stackoverflow).

• Cutting down repeating code in c# Class

  - by Tom Gullen

  This is a wrapper for an API I'm working on, am I doing it sort of right? I'm not particularly fond of all the repeating code in the constructor, if someone can show me if I can reduce that it would be very helpful! public class WebWizForumVersion { // Properties of returned data public string Software { get; private set; } public string Version { get; private set; } public string APIVersion { get; private set; } public string Copyright { get; private set; } public string BoardName { get; private set; } public string URL { get; private set; } public string Email { get; private set; } public string Database { get; private set; } public string InstallationID { get; private set; } public bool NewsPad { get; private set; } public string NewsPadURL { get; private set; } public WebWizForumVersion(XmlReader Data) { try { Data.ReadToFollowing("Software"); this.Software = Data.ReadElementContentAsString(); Data.ReadToFollowing("Version"); this.Version = Data.ReadElementContentAsString(); Data.ReadToFollowing("ApiVersion"); this.APIVersion = Data.ReadElementContentAsString(); Data.ReadToFollowing("Copyright"); this.Copyright = Data.ReadElementContentAsString(); Data.ReadToFollowing("BoardName"); this.BoardName = Data.ReadElementContentAsString(); Data.ReadToFollowing("URL"); this.URL = Data.ReadElementContentAsString(); Data.ReadToFollowing("Email"); this.Email = Data.ReadElementContentAsString(); Data.ReadToFollowing("Database"); this.Database = Data.ReadElementContentAsString(); Data.ReadToFollowing("InstallID"); this.InstallationID = Data.ReadElementContentAsString(); Data.ReadToFollowing("NewsPad"); this.NewsPad = bool.Parse(Data.ReadElementContentAsString()); Data.ReadToFollowing("NewsPadURL"); this.NewsPadURL = Data.ReadElementContentAsString(); } catch (Exception e) { } } }

• DataGrid : Binding with two different classes with lists ? WPF C#

  - by MyRestlessDream

  It is my first question on StackOverflow so I hope I am doing nothing wrong ! Sorry if it is the case ! I need some help because I can not find the solution of my problem. Of course I have searched everywhere on the web but I can not find it (can not post the links that I am using because of my low reputation :( ). Moreover, I am new in C# and WPF (and self-learning). I used to work in C++/Qt so I do not know how everything works in WPF. And sorry for my English, I am French. My problem My basic classes are that an Employee can use a computer. The id of the computer and the date of use are stored into the class Connection. I would like to display the list information in a DataGrid and in RowDetailsTemplate like here : http://i.stack.imgur.com/Bvn1z.png So it will do a binding to the Employee class but also to the Connection class with only the last value of the property (here the last value of the list "Computer ID" and the last value of the list "Connection Date" on this last computer). So it is a loop in the different lists. How can I do it ? Is it too much to do ? :( I succeed to get the Employee informations but I do not know how to bind the list of computer. When I am trying, it shows me "(Collection)" so it does not go inside the list :( Summary of Questions How to display/bind a value from a list AND from a different class in a DataGrid ? How to display all the values of a list into the RowDetailsTemplate ? Under Windows 7 and Visual Studio 2010 Pro version. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ EDIT ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Solution I have used the solution of Stefan Denchev. Here the modification of my class : http://i.stack.imgur.com/Ijx5i.png And the code used: <DataGrid ItemsSource="{Binding}" Name="table"> <DataGrid.Columns> <DataGridTextColumn Header="First Name" Binding="{Binding FirstName}"/> <DataGridTextColumn Header="Last Name" Binding="{Binding LastName}"/> <DataGridTextColumn Header="Gender" Binding="{Binding Gender}"/> <DataGridTextColumn Header="Last computer used" Binding="{Binding LastComputerID}"/> <DataGridTextColumn Header="Last connection date" Binding="{Binding LastDate}"/> </DataGrid.Columns> <DataGrid.RowDetailsTemplate> <DataTemplate> <DataGrid ItemsSource="{Binding ListOfConnection}"> <DataGrid.Columns> <DataGridTextColumn Header="Computer ID" Binding="{Binding ComputerID}"/> <DataGridTemplateColumn> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <ListView ItemsSource="{Binding ListOfDate}"/> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> </DataGrid.Columns> </DataGrid> </DataTemplate> </DataGrid.RowDetailsTemplate> </DataGrid> With in code behind : List<Employee> allEmployees = WorkflowMgr.Instance.AllEmployees; table.DataContext = allEmployees; And it works ! I have tryed to improve my fake example :) Hope it will help to another developer !

• How do I simplify this php script

  - by user225269

  Any suggestions on how I can simplify the php script below?This was my previous question: http://stackoverflow.com/questions/2712237/how-to-check-if-a-checkbox-radio-button-is-checked-in-php that is linked to this one, What I'm trying to do here is to output the data depending on the checkbox that is checked. But my code isn't really good, it shows 2 tables if the condition is met by the 2 results. As you can see in the code below, any suggestions on how I can simplify this? <?php $con = mysql_connect("localhost","root","nitoryolai123$%^"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("school", $con); $id = mysql_real_escape_string($_POST['idnum']); if ( $_POST['yr'] == 'year' and $_POST['sec'] == 'section' ){ $result2 = mysql_query("SELECT * FROM student WHERE IDNO='$id'"); echo "<table border='1'> <tr> <th>IDNO</th> <th>YEAR</th> <th>SECTION</th> </tr>"; while($row = mysql_fetch_array($result2)) { echo "<tr>"; echo "<td>" . $row['IDNO'] .

• Terminating a long-executing thread and then starting a new one in response to user changing parameters via UI in an applet

  - by user1817170

  I have an applet which creates music using the JFugue API and plays it for the user. It allows the user to input a music phrase which the piece will be based on, or lets them choose to have a phrase generated randomly. I had been using the following method (successfully) to simply stop and start the music, which runs in a thread using the Player class from JFugue. I generate the music using my classes and user input from the applet GUI...then... private playerThread pthread; private Thread threadPlyr; private Player player; (from variables declaration) public void startMusic(Pattern p) // pattern is a JFugue object which holds the generated music { if (pthread == null) { pthread = new playerThread(); } else { pthread = null; pthread = new playerThread(); } if (threadPlyr == null) { threadPlyr = new Thread(pthread); } else { threadPlyr = null; threadPlyr = new Thread(pthread); } pthread.setPattern(p); threadPlyr.start(); } class playerThread implements Runnable // plays midi using jfugue Player { private Pattern pt; public void setPattern(Pattern p) { pt = p; } @Override public void run() { try { player.play(pt); // takes a couple mins or more to execute resetGUI(); } catch (Exception exception) { } } } And the following to stop music when user presses the stop/start button while Player.isPlaying() is true: public void stopMusic() { threadPlyr.interrupt(); threadPlyr = null; pthread = null; player.stop(); } Now I want to implement a feature which will allow the user to change parameters while the music is playing, create an updated music pattern, and then play THAT pattern. Basically, the idea is to make it simulate "real time" adjustments to the generated music for the user. Well, I have been beating my head against the wall on this for a couple of weeks. I've read all the standard java documentation, researched, read, and searched forums, and I have tried many different ideas, none of which have succeeded. The problem I've run into with all approaches I've tried is that when I start the new thread with the new, updated musical pattern, all the old threads ALSO start, and there is a cacophony of unintelligible noise instead of my desired output. From what I've gathered, the issue seems to be that all the methods I've come across require that the thread is able to periodically check the value of a "flag" variable and then shut itself down from within its "run" block in response to that variable. However, since my thread makes a call that takes several minutes minimum to execute (playing the music), and I need to terminate it WHILE it is executing this, there is really no safe way to do so. So, I'm wondering if there is something I'm missing when it comes to threads, or if perhaps I can accomplish my goal using a totally different approach. Any ideas or guidance is greatly appreciated! Thank you!

• Best way to program a call to php

  - by hairdresser-101

  I've recently posted here http://stackoverflow.com/questions/2627645/accessing-session-when-using-file-get-contents-in-php about a problem I was having and the general consensus is that I'm not doing it right... while I generally think "as long as it works..." I thought I'd get some feedback on how I could do it better... I was to send the exact same email in the exact same format from multiple different areas. When a job is entered (automatically as a part of the POST) Manually when reviewing jobs to re-assign to another installer The original script is a php page which is called using AJAX to send the work order request - this worked by simply calling a standard php page, returning the success or error message and then displaying within the calling page. Now I have tried to use the same page within the automated job entry so it accepts the job via a form, logs it and mails it. My problem is (as you can see from the original post) the function file_get_contents() is not good for this cause in the automated script... My problem is that from an AJAX call I need to do things like include the database connection initialiser, start the session and do whatever else needs to be done in a standalone page... Some or all of these are not required if it is an include so it makes the file only good for one purpose... How do I make the file good for both purposes? I guess I'm looking for recommendations for the best file layout and structure to cater for both scenarios... The current file looks like: <?php session_start(); $order_id = $_GET['order_id']; include('include/database.php'); function getLineItems($order_id) { $query = mysql_query("SELECT ...lineItems..."); //Print rows with data while($row = mysql_fetch_object($query)) { $lineItems .= '...Build Line Item String...'; } return $lineItems; } function send_email($order_id) { //Get data for current job to display $query = mysql_query("SELECT ...Job Details..."); $row = mysql_fetch_object($query); $subject = 'Work Order Request'; $email_message = '...Build Email... ...Include Job Details... '.getLineItems($order_id).' ...Finish Email...'; $headers = '...Create Email Headers...'; if (mail($row->primary_email, $subject, $email_message, $headers)) { $query = mysql_query("...log successful send..."); if (mysql_error()!="") { $message .= '...display mysqlerror()..'; } $message .= '...create success message...'; } else { $query = mysql_query("...log failed send..."); if (mysql_error()!="") { $message .= '...display mysqlerror()..'; } $message .= '...create failed message...'; } return $message; } // END send_email() function //Check supplier info $query = mysql_query("...get suppliers info attached to order_id..."); if (mysql_num_rows($query) > 0) { while($row = mysql_fetch_object($query)) { if ($row->primary_email=="") { $message .= '...no email message...'; } else if ($row->notification_email=="") { $message .= '...no notifications message...'; } else { $message .= send_email($order_id); } } } else { $message .= '...no supplier matched message...'; } print $message; ?>

• 500 Metro Style WP7 Icons

  - by Bil Simser

  I was inspired by The Noun Project, a project that offers up “Metro-style” icons in SVG format. The project is licensed under a public domain license and while it’s a great project, all of the content is in SVG format. Jon Galloway has a great post (from 2007) talking about the differences between SVG and XAML so I highly recommend that for some background. I thought it would be helpful to the WPF/Windows Phone 7/Silverlight community to provide the content in alternative formats for use in your applications. The Goods I’ve put together a package of the 500 icons (502 actually) in PNG, XAML and the original SVG format along with a couple of sample projects so you can see them in action. There’s a WPF desktop app: And a Windows Phone 7 app: Building It To get all the content first I wrote up a quick program to suck the original SVG files. Luckily they’re all in a common path just named 1.SVG, 2.SVG, and so on. Easy sleazy to grab the contents. Once I had 500 SVG files I used the latest copy of XamlTune, an open source CodePlex project that has a command line conversion tool to convert the directory of SVG files into XAML (the tool also created a PNG file of each SVG so that’s just icing on the cake). Conversions The conversion from SVG to XAML isn’t 100%. While you can just drop the content into a WPF app, it doesn’t work that way for WP7. There are just some small adjustments I made to each format so you’ll have to do the same. Follow the information below or refer to the sample applications. As a sample, here’s an icon we want to use: Here’s the original SVG file: <svg version="1.0" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="100px" height="94.616px" viewBox="0 0 100 94.616" enable-background="new 0 0 100 94.616" xml:space="preserve"> <path d="M25.076,15.639c4.324,0.009,7.824-3.488,7.82-7.82C32.9,3.512,29.4,0.012,25.076,0c-4.313,0.012-7.814,3.512-7.821,7.819 C17.262,12.15,20.763,15.648,25.076,15.639L25.076,15.639z"/> <path d="M4.593,43.388h6.861l4.137-15.135h1.716L13.22,43.388h24.318l-4.389-15.135h1.817l2.32,7.415 c1.08,3.131,3.852,3.851,6.003,1.162l8.375-10.142c2.651-3.42-2.104-7.021-4.844-4.035l-4.993,5.952 c0.007,0.095-0.96-3.278-0.96-3.278c-1.135-3.978-4.918-7.903-10.595-7.922H19.576c-5.071,0.019-9.043,4.434-9.888,7.214 L4.593,43.388L4.593,43.388z"/> <polygon points="56.206,22.753 56.206,7.163 49.192,7.163 49.192,22.753 56.206,22.753 "/> <path d="M79.87,15.738c4.332-0.014,7.831-3.516,7.82-7.82c0.011-4.332-3.488-7.833-7.82-7.82c-4.306-0.013-7.806,3.488-7.821,7.82 C72.064,12.222,75.564,15.725,79.87,15.738L79.87,15.738z"/> <path d="M89.759,89.556v-43.19h5.751V22.804c0.007-3.079-2.757-5.448-6.71-5.449H70.436c-3.65,0.001-4.539,1.186-5.551,2.168 L49.597,37.889c-3.098,3.848,2.428,8.333,5.55,4.743L69.88,25.226v64.43c-0.019,6.475,9.06,6.686,9.081,0.201v-36.58h1.765v36.379 C80.748,96.109,89.772,96.13,89.759,89.556L89.759,89.556z"/> <polygon points="100,54.035 100,45.155 0,45.155 0,54.035 100,54.035 "/> </svg> Here’s the XAML that XamlTune created.

Note that while it does show up in the app (on the emulator or device) it wouldn’t show up in Visual Studio for me. Maybe some XAML guru out there can tell me why. You can just as easily use the PNG files in WP7 but if you want the crispness of vector graphics, go for the XAML version. Of course with XamlTune being open source you could always modify the output of that program to cater it to your app. If you do make a change that’s worthy please consider submitting a patch to the project so everyone can benefit. Hope this helps and happy programming!

• Enumerable Interleave Extension Method

  - by João Angelo

  A recent stackoverflow question, which I didn’t bookmark and now I’m unable to find, inspired me to implement an extension method for Enumerable that allows to insert a constant element between each pair of elements in a sequence. Kind of what String.Join does for strings, but maintaining an enumerable as the return value. Having done the single element part I got a bit carried away and ended up expanding it adding overloads to support interleaving elements of another sequence and support for a predicate to control when interleaving takes place. I have to confess that I did this for fun and now I can’t think of any real usage scenario, nonetheless, it may prove useful for someone. First a simple example: var target = new string[] { "(", ")", "(", ")" }; var result = target.Interleave(".", (f, s) => f == "("); // Prints: (.)(.) Console.WriteLine(String.Join(string.Empty, result)); And now the untested but documented implementation: using System; using System.Collections; using System.Collections.Generic; using System.Linq; public static class EnumerableExtensions { /// <summary> /// Iterates infinitely over a constant element. /// </summary> /// <typeparam name="T"> /// The type of element in the sequence. /// </typeparam> private class InfiniteSequence<T> : IEnumerable<T>, IEnumerator<T> { public InfiniteSequence(T element) { this.Element = element;

• Writing custom Message Formatter for SOAP basicHttpBinding

  - by Lijo

  I have a WSDL published by our service development team. It is using SOAP and basicHttpBinding. I can add the service reference to the project using Add Service Reference option in Visual Studio. I need to develop the WCF client. I need to use custom Message Formatter (for mapping between Messages and CLR types). Can you please show how to write the custom Message Formatter (in C# )for the following wsdl?

• Apache 2.2 and FastCGI stops responding, warnings, crashes

  - by Brett

  I've seen this question posted a few times using a Google search, with no real answers. I have a multi-threaded FastCGI application running with Apache 2.2 on FreeBSD 7.2. There are a few issues with it, and I am unable to really figure out the source of the problem even after poking through a bunch of the mod_fastcgi source code. My FastCGI application gets anywhere from 2 to 15 or so hits per second, and mostly services a back-end API (the majority of web server usage is for this, and not actually serving content). Everything seems to work ok under normal conditions, but recently this problem has been becoming worse. It starts out with the FastCGI process manager apparently trying to close unneeded processes, sending them a SIGTERM signal. I catch the signal, clean up some stuff, and exit (by calling exit()) with status code 0. This process seems to result in three log messages in my httpd error log: [Tue Jun 01 14:03:31 2010] [warn] FastCGI: (dynamic) server "/home/program/wwwroot/domains/www.mydomain.com/cgi-bin/program.cgi" (pid 98182) termination signaled [Tue Jun 01 14:03:31 2010] [warn] FastCGI: (dynamic) server "/home/program/wwwroot/domains/www.mydomain.com/cgi-bin/program.cgi" (pid 98182) terminated by calling exit with status '0' [Tue Jun 01 14:03:31 2010] [warn] FastCGI: (dynamic) server "/home/program/wwwroot/domains/www.mydomain.com/cgi-bin/program.cgi" restarted (pid 98294) I am not sure why it says it is restarting the process, but in any case no core dump is ever generated so I do believe it is the FastCGI process manager doing it's thing. This makes sense because it begins to happen after the initial load increase from restarting Apache. Since it's down for a few seconds, it gets hit with a couple of hundred requests over the first few seconds it's running again (sometimes even hitting the upper limit of MAXCLIENTS in Apache), and this seems to be the process manager doing the work of spawning more processes to handle the increased load. So this all seems fine, but here is where things get weird. There are really two problems that I see. First, my multithreaded FastCGI process spawns 25 worker threads, and all seem to be used according to my internal log files (multiple processes are clearly using multiple threads to do work). However it seems that 3 or 4 FastCGI processes is not enough to handle the 5 to 15 hit per second load, even though the requests take about .02s or so to process internally. In order to be at all responsive, it seems I need 50 or more FastCGI processes, leading me to believe that FastCGI does not realize that my program is multithreaded. I've read the documentation at http://www.fastcgi.com/mod_fastcgi/docs/mod_fastcgi.html and do not see any option pertaining to multithreaded-ness, and my internal code is more or less set up just like the examples provided by the FastCGI library. The second problem I am having is that once process termination has happened a bunch of times as above (and seemingly at random), I begin getting a lot of these messages in my error log: [Tue Jun 01 14:06:22 2010] [warn] (32)Broken pipe: FastCGI: write() to PM failed (ignore if a restart or shutdown is pending) The messages occur for about half the hits I get to the server, and it completely kills the responsiveness of my application - it seems FastCGI will look for a working "pipe" until it finds one, and fail to realize that whatever application it is trying to contact is dead. It does still work though, it's just incredibly unresponsive - sometimes taking up to 40 or so seconds to process a request. I recompiled mod_fastcgi with some extra debugging around the point of the error message, and it appears that the error happens when it tries to write() to the application. The call to write() fails with a -1 return code, and sets errno to EPIPE. I am noticing that the issue happens mostly when either a crash occurs in one of the FastCGI processes, or a bunch of them are seemingly terminated by the process manager. I haven't had any core dumps though, except for one, where the backtrace outputted by gdb is just a single call to free() at address 0x0000000000000000 with nothing else in the stack trace, so I don't really know what to make of that. I'm thinking it happens sometime after the SIGTERM signal is caught, maybe some global variable not being cleaned up properly or something.

• Nagios notifications definitions

  - by Colin

  I am trying to monitor a web server in such a way that I want to search for a particular string on a page via http. The command is defined in command.cfg as follows # 'check_http-mysite command definition' define command { command_name check_http-mysite command_line /usr/lib/nagios/plugins/check_http -H mysite.example.com -s "Some text" } # 'notify-host-by-sms' command definition define command { command_name notify-host-by-sms command_line /usr/bin/send_sms $CONTACTPAGER$ "Nagios - $NOTIFICATIONTYPE$ :Host$HOSTALIAS$ is $HOSTSTATE$ ($OUTPUT$)" } # 'notify-service-by-sms' command definition define command { command_name notify-service-by-sms command_line /usr/bin/send_sms $CONTACTPAGER$ "Nagios - $NOTIFICATIONTYPE$: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ ($OUTPUT$)" } Now if nagios doesn't find "Some text" on the home page mysite.example.com, nagios should notify a contact via sms through the Clickatell http API which I have a script for that that I have tested and found that it works fine. Whenever I change the command definition to search for a string which is not on the page, and restart nagios, I can see on the web interface that the string was not found. What I don't understand is why isn't the notification sent though I have defined the host, hostgroup, contact, contactgroup and service and so forth. What I'm I missing, these are my definitions, In my web access through the cgi I can see that I have notifications have been defined and enabled though I don't get both email and sms notifications during hard status changes. host.cfg define host { use generic-host host_name HAL alias IBM-1 address xxx.xxx.xxx.xxx check_command check_http-mysite } *hostgroups_nagios2.cfg* # my website define hostgroup{ hostgroup_name my-servers alias All My Servers members HAL } *contacts_nagios2.cfg* define contact { contact_name colin alias Colin Y service_notification_period 24x7 host_notification_period 24x7 service_notification_options w,u,c,r,f,s host_notification_options d,u,r,f,s service_notification_commands notify-service-by-email,notify-service-by-sms host_notification_commands notify-host-by-email,notify-host-by-sms email [email protected] pager +254xxxxxxxxx } define contactgroup{ contactgroup_name site_admin alias Site Administrator members colin } *services_nagios2.cfg* # check for particular string in page via http define service { hostgroup_name my-servers service_description STRING CHECK check_command check_http-mysite use generic-service notification_interval 0 ; set > 0 if you want to be renotified contacts colin contact_groups site_admin } Could someone please tell me where I'm going wrong.

• Configuring dhcp module in FreeRadius (3.0.2 - Centos 6.5)

  - by mixja

  I am using the REST module to authorise a DHCP request. I would like to send an explicit DHCP NAK if the authorisation fails, however the DHCP module seems to return immediately if there is a failure and just ignores the DHCP request without any response. Here is my DHCP module configuration - if rest.authorize is successful, the if (ok) control block is hit, but if rest.authorize fails the if (fail) is never hit. dhcp DHCP-Discover { rest.authorize if (fail) { update reply { DHCP-Message-Type = DHCP-Nak } } if (ok) { update reply { DHCP-Message-Type = DHCP-Offer } update reply { DHCP-Domain-Name-Server = x.x.x.x DHCP-Domain-Name-Server = x.x.x.x DHCP-Subnet-Mask = 255.255.255.0 DHCP-Router-Address = x.x.x.x DHCP-IP-Address-Lease-Time = 3600 DHCP-DHCP-Server-Identifier = x.x.x.x } mac2ip } } Below is the output after a 401 Unauthorized is received. I am wanting to achieve a temporary block on DHCP for a specified (small) period of time. However the FreeRADIUS behaviour is to ignore duplicate requests for same DHCP transaction, meaning DHCP on client is blocked until it begins a new transaction. If a DHCP NAK can be sent, the DHCP client will initiate a new transaction after each NAK (i.e. DHCP Discover), meaning FreeRADIUS will process each DHCP Discover from the client, and the block will be removed much closer to the desired block time.

• Pushing DNSSEC updates with offline keys

  - by eggyal

  In a non-professional capacity, I look after the DNS of some 18 domains: mostly personal/vanity domains for immediate family. I outsource the whole shebang to an inexpensive managed hosting provider with a web interface through which I manage the zones; since the provider also offers DNSSEC, I have successfully deployed that too. These domains are so unimportant that an attack targetted against them seems much less likely than a general compromise of my provider's systems, at which point the records of all their customers might be changed to misdirect traffic (perhaps with extremely long TTLs). DNSSEC could protect against such an attack, but only if the zone's private keys are not held by the hosting provider. So, I wonder: how can one keep DNSSEC private keys offline yet still transfer signed zones to an outsourced DNS host? The most obvious answer (to me, at least) is to run one's own shadow/hidden master (from which the provider can slave) and then copy offline-signed zonefiles to the master as required. The problem is that the only machine I (want to*) control is my personal laptop, which usually connects from a typical home ADSL (behind NAT over a dynamically-assigned IP address). Having them slave from that (e.g. with a very long Expiry time on the zone for periods when my laptop is offline/unavailable) would not only require a Dynamic DNS record from which they can slave (if indeed they can slave from a named host rather than a static IP address), but would also involve me running a DNS server on my laptop and opening both it and my home network up to the incoming zone transfer requests: not ideal. I would prefer a much more push-oriented design, whereby my laptop initiates transfer of offline-signed zonefiles/updates to the provider's servers. I looked into whether nsupdate could fit the bill: documentation is a little sketchy, but my testing (with BIND 9.7) suggests it can indeed update DNSSEC zones, but only where the server holds the keys to perform the zone signing; I have not found a way to have it take an update including the relevant RRSIG/NSEC/etc. records and have the server accept them. Is this a supported use-case? If not, I suspect the only solutions which could fit the bill will involve non-DNS-based transfer of the zone updates and would welcome recommendations that are supported by (hopefully inexpensive) hosting providers: SFTP/SCP? rsync? RDBMS replication? Proprietary API? Finally, what would be the practical implications of such a setup? Key rotation is jumping out at me as being an obvious difficulty, especially if my laptop is offline for extended periods. But the zones are extremely stable, so perhaps I could get away with long-lived ZSKs**...? * Whilst I could run a shadow/hidden master on e.g. an outsourced VPS, I dislike the overhead of having to secure / manage / monitor / maintain yet another system; not to mention the additional financial costs of so doing. ** Okay, this would enable a concerted attacker to replay outdated records—but the risk and impact of such are both tolerable in the case of these domains.

• How does the Cloud compare to Colocation? And development too

  - by David

  Currently I/we run a SaaS web application where each subscriber has their own physical instance of the application in addition to their own database. The setup has each web application instance deployed on two different IIS boxes both for load-balancing and redundancy (the machines have their Windows Update install times 12 hours apart, for example). Databases are mirrored on two different SQL Server 2012 machines with AlwaysOn for uptime. I don't make use of SQL Server clustering (as it doesn't provide storage-level failover: we don't have a shared storage box). Because it's a Windows setup it means there are two Domain Controllers (we cheat: they're both Mac Minis, 17W each, which keeps our colo power costs low). Finally there's also an Exchange server (Mailbox, Hub Transport and Client Access). One of the SQL Servers also doubles-up as an Exchange Hub Transport. Running costs are about $700 a month for our quarter-rack colocation (which includes power and peering/transfer), then there's about $150 a month for SPLA licensing, so $850 a month in total. Then there's the hard-to-quantify cost of administration, but I reckon I spend a couple of hours a week checking-in on the servers: reviewing event logs, etc. I keep getting bombarded by ads and manufactured news stories about how great "the cloud" is. Back in 2008 when the cloud was taking off I was reading up about the proper "cloud" services like Google AppEngine, where you write in Python against Google's API and that's how they scale your application across servers and also use their database provider for scaling storage. Simple enough to understand. Then came along Amazon, and I understand how Amazon Storage works, but I'm not sure how Amazon Compute works: web application pages don't take much CPU time to compute, how do you even quantify usage anyway? Finally, RackSpace gets in the act and now I'm really confused. RackSpace advertise "Cloud" SQL Server 2012 available for about "$0.70 per hour", going by how they advertise it I thought the "hour" meant the sum of CPU time, IO blocking time, maybe time spent transferring data, so for a low-intensity application that works out pretty cheap then? Nope. I went on to a Sales Chat window and spoke to one of their advisors. They told me the $0.70/hour was actually for every hour the SQL Server is running... but who wants a SQL Server for only a few hours? You're going to need it available 24 hours a day for months on end. $0.70 * 24 * 31 works out at $520 a month, which is rediculously expensive for SQL Server. An SPLA license for SQL Server is only $50 a month or so. That $520 a month does not include "fanatical support", and you also need to stack on top the costs of the host Windows server instance too. From what I can tell, Rackspace's "Cloud" products seem like like an cynical rebranding of an overpriced VPS service, but priced by the hour. I have the same confusion about Windows Azure which uses similar terms to describe the products available, but I think that's because Azure offers both traditional shared webhosting in addition to their own APIs you can target for scalable applications.

• The dynamic Type in C# Simplifies COM Member Access from Visual FoxPro

  - by Rick Strahl

  I’ve written quite a bit about Visual FoxPro interoperating with .NET in the past both for ASP.NET interacting with Visual FoxPro COM objects as well as Visual FoxPro calling into .NET code via COM Interop. COM Interop with Visual FoxPro has a number of problems but one of them at least got a lot easier with the introduction of dynamic type support in .NET. One of the biggest problems with COM interop has been that it’s been really difficult to pass dynamic objects from FoxPro to .NET and get them properly typed. The only way that any strong typing can occur in .NET for FoxPro components is via COM type library exports of Visual FoxPro components. Due to limitations in Visual FoxPro’s type library support as well as the dynamic nature of the Visual FoxPro language where few things are or can be described in the form of a COM type library, a lot of useful interaction between FoxPro and .NET required the use of messy Reflection code in .NET. Reflection is .NET’s base interface to runtime type discovery and dynamic execution of code without requiring strong typing. In FoxPro terms it’s similar to EVALUATE() functionality albeit with a much more complex API and corresponiding syntax. The Reflection APIs are fairly powerful, but they are rather awkward to use and require a lot of code. Even with the creation of wrapper utility classes for common EVAL() style Reflection functionality dynamically access COM objects passed to .NET often is pretty tedious and ugly. Let’s look at a simple example. In the following code I use some FoxPro code to dynamically create an object in code and then pass this object to .NET. An alternative to this might also be to create a new object on the fly by using SCATTER NAME on a database record. How the object is created is inconsequential, other than the fact that it’s not defined as a COM object – it’s a pure FoxPro object that is passed to .NET. Here’s the code: *** Create .NET COM InstanceloNet = CREATEOBJECT('DotNetCom.DotNetComPublisher') *** Create a Customer Object Instance (factory method) loCustomer = GetCustomer() loCustomer.Name = "Rick Strahl" loCustomer.Company = "West Wind Technologies" loCustomer.creditLimit = 9999999999.99 loCustomer.Address.StreetAddress = "32 Kaiea Place" loCustomer.Address.Phone = "808 579-8342" loCustomer.Address.Email = "[email protected]" *** Pass Fox Object and echo back values ? loNet.PassRecordObject(loObject) RETURN FUNCTION GetCustomer LOCAL loCustomer, loAddress loCustomer = CREATEOBJECT("EMPTY") ADDPROPERTY(loCustomer,"Name","") ADDPROPERTY(loCustomer,"Company","") ADDPROPERTY(loCUstomer,"CreditLimit",0.00) ADDPROPERTY(loCustomer,"Entered",DATETIME()) loAddress = CREATEOBJECT("Empty") ADDPROPERTY(loAddress,"StreetAddress","") ADDPROPERTY(loAddress,"Phone","") ADDPROPERTY(loAddress,"Email","") ADDPROPERTY(loCustomer,"Address",loAddress) RETURN loCustomer ENDFUNC Now prior to .NET 4.0 you’d have to access this object passed to .NET via Reflection and the method code to do this would looks something like this in the .NET component: public string PassRecordObject(object FoxObject) { // *** using raw Reflection string Company = (string) FoxObject.GetType().InvokeMember( "Company", BindingFlags.GetProperty,null, FoxObject,null); // using the easier ComUtils wrappers string Name = (string) ComUtils.GetProperty(FoxObject,"Name"); // Getting Address object – then getting child properties object Address = ComUtils.GetProperty(FoxObject,"Address");    string Street = (string) ComUtils.GetProperty(FoxObject,"StreetAddress"); // using ComUtils 'Ex' functions you can use . Syntax     string StreetAddress = (string) ComUtils.GetPropertyEx(FoxObject,"AddressStreetAddress"); return Name + Environment.NewLine + Company + Environment.NewLine + StreetAddress + Environment.NewLine + " FOX"; } Note that the FoxObject is passed in as type object which has no specific type. Since the object doesn’t exist in .NET as a type signature the object is passed without any specific type information as plain non-descript object. To retrieve a property the Reflection APIs like Type.InvokeMember or Type.GetProperty().GetValue() etc. need to be used. I made this code a little simpler by using the Reflection Wrappers I mentioned earlier but even with those ComUtils calls the code is pretty ugly requiring passing the objects for each call and casting each element. Using .NET 4.0 Dynamic Typing makes this Code a lot cleaner Enter .NET 4.0 and the dynamic type. Replacing the input parameter to the .NET method from type object to dynamic makes the code to access the FoxPro component inside of .NET much more natural: public string PassRecordObjectDynamic(dynamic FoxObject) { // *** using raw Reflection string Company = FoxObject.Company; // *** using the easier ComUtils class string Name = FoxObject.Name; // *** using ComUtils 'ex' functions to use . Syntax string Address = FoxObject.Address.StreetAddress; return Name + Environment.NewLine + Company + Environment.NewLine + Address + Environment.NewLine + " FOX"; } As you can see the parameter is of type dynamic which as the name implies performs Reflection lookups and evaluation on the fly so all the Reflection code in the last example goes away. The code can use regular object ‘.’ syntax to reference each of the members of the object. You can access properties and call methods this way using natural object language. Also note that all the type casts that were required in the Reflection code go away – dynamic types like var can infer the type to cast to based on the target assignment. As long as the type can be inferred by the compiler at compile time (ie. the left side of the expression is strongly typed) no explicit casts are required. Note that although you get to use plain object syntax in the code above you don’t get Intellisense in Visual Studio because the type is dynamic and thus has no hard type definition in .NET . The above example calls a .NET Component from VFP, but it also works the other way around. Another frequent scenario is an .NET code calling into a FoxPro COM object that returns a dynamic result. Assume you have a FoxPro COM object returns a FoxPro Cursor Record as an object: DEFINE CLASS FoxData AS SESSION OlePublic cAppStartPath = "" FUNCTION INIT THIS.cAppStartPath = ADDBS( JustPath(Application.ServerName) ) SET PATH TO ( THIS.cAppStartpath ) ENDFUNC FUNCTION GetRecord(lnPk) LOCAL loCustomer SELECT * FROM tt_Cust WHERE pk = lnPk ; INTO CURSOR TCustomer IF _TALLY < 1 RETURN NULL ENDIF SCATTER NAME loCustomer MEMO RETURN loCustomer ENDFUNC ENDDEFINE If you call this from a .NET application you can now retrieve this data via COM Interop and cast the result as dynamic to simplify the data access of the dynamic FoxPro type that was created on the fly: int pk = 0; int.TryParse(Request.QueryString["id"],out pk); // Create Fox COM Object with Com Callable Wrapper FoxData foxData = new FoxData(); dynamic foxRecord = foxData.GetRecord(pk); string company = foxRecord.Company; DateTime entered = foxRecord.Entered; This code looks simple and natural as it should be – heck you could write code like this in days long gone by in scripting languages like ASP classic for example. Compared to the Reflection code that previously was necessary to run similar code this is much easier to write, understand and maintain. For COM interop and Visual FoxPro operation dynamic type support in .NET 4.0 is a huge improvement and certainly makes it much easier to deal with FoxPro code that calls into .NET. Regardless of whether you’re using COM for calling Visual FoxPro objects from .NET (ASP.NET calling a COM component and getting a dynamic result returned) or whether FoxPro code is calling into a .NET COM component from a FoxPro desktop application. At one point or another FoxPro likely ends up passing complex dynamic data to .NET and for this the dynamic typing makes coding much cleaner and more readable without having to create custom Reflection wrappers. As a bonus the dynamic runtime that underlies the dynamic type is fairly efficient in terms of making Reflection calls especially if members are repeatedly accessed. © Rick Strahl, West Wind Technologies, 2005-2010Posted in COM  FoxPro  .NET  CSharp

• Integrate SharePoint 2010 with Team Foundation Server 2010

  - by Martin Hinshelwood

  Our client is using a brand new shiny installation of SharePoint 2010, so we need to integrate our upgraded Team Foundation Server 2010 instance into it. In order to do that you need to run the Team Foundation Server 2010 install on the SharePoint 2010 server and choose to install only the “Extensions for SharePoint Products and Technologies”. We want out upgraded Team Project Collection to create any new portal in this SharePoint 2010 server farm. There a number of goodies above and beyond a solution file that requires the install, with the main one being the TFS2010 client API. These goodies allow proper integration with the creation and viewing of Work Items from SharePoint a new feature with TFS 2010. This works in both SharePoint 2007 and SharePoint 2010 with the level of integration dependant on the version of SharePoint that you are running. There are three levels of integration with “SharePoint Services 3.0” or “SharePoint Foundation 2010” being the lowest. This level only offers reporting services framed integration for reporting along with Work Item Integration and document management. The highest is Microsoft Office SharePoint Services (MOSS) Enterprise with Excel Services integration providing some lovely dashboards. Figure: Dashboards take the guessing out of Project Planning and estimation. Plus writing these reports would be boring!   The Extensions that you need are on the same installation media as the main TFS install and the only difference is the options you pick during the install. Figure: Installing the TFS 2010 Extensions for SharePoint Products and Technologies onto SharePoint 2010   Annoyingly you may need to reboot a couple of times, but on this server the process was MUCH smother than on our internal server. I think this was mostly to do with this being a clean install. Once it is installed you need to run the configuration. This will add all of the Solution and Templates that are needed for SharePoint to work properly with TFS. Figure: This is where all the TFS 2010 goodies are added to your SharePoint 2010 server and the TFS 2010 object model is installed.   Figure: All done, you have everything installed, but you still need to configure it Now that we have the TFS 2010 SharePoint Extensions installed on our SharePoint 2010 server we need to configure them both so that they will talk happily to each other. Configuring the SharePoint 2010 Managed path for Team Foundation Server 2010 In order for TFS to automatically create your project portals you need a wildcard managed path setup. This is where TFS will create the portal during the creation of a new Team project. To find the managed paths page for any application you need to first select the “Managed web applications”  link from the SharePoint 2010 Central Administration screen. Figure: Find the “Manage web applications” link under the “Application Management” section. On you are there you will see that the “Managed Paths” are there, they are just greyed out and selecting one of the applications will enable it to be clicked. Figure: You need to select an application for the SharePoint 2010 ribbon to activate.   Figure: You need to select an application before you can get to the Managed Paths for that application. Now we need to add a managed path for TFS 2010 to create its portals under. I have gone for the obvious option of just calling the managed path “TFS02” as the TFS 2010 server is the second TFS server that the client has installed, TFS 2008 being the first. This links the location to the server name, and as you can’t have two projects of the same name in two separate project collections there is unlikely to be any conflicts. Figure: Add a “tfs02” wildcard inclusion path to your SharePoint site. Configure the Team Foundation Server 2010 connection to SharePoint 2010 In order to have you new TFS 2010 Server talk to and create sites in SharePoint 2010 you need to tell the TFS server where to put them. As this TFS 2010 server was installed in out-of-the-box mode it has a SharePoint Services 3.0 (the free one) server running on the same box. But we want to change that so we can use the external SharePoint 2010 instance. Just open the “Team Foundation Server Administration Console” and navigate to the “SharePoint Web Applications” section. Here you click “Add” and enter the details for the Managed path we just created. Figure: If you have special permissions on your SharePoint you may need to add accounts to the “Service Accounts” section.    Before we can se this new SharePoint 2010 instance to be the default for our upgraded Team Project Collection we need to configure SharePoint to take instructions from our TFS server. Configure SharePoint 2010 to connect to Team Foundation Server 2010 On your SharePoint 2010 server open the Team Foundation Server Administration Console and select the “Extensions for SharePoint Products and Technologies” node. Here we need to “grant access” for our TFS 2010 server to create sites. Click the “Grant access” link and  fill out the full URL to the  TFS server, for example http://servername.domain.com:8080/tfs, and if need be restrict the path that TFS sites can be created on. Remember that when the users create a new team project they can change the default and point it anywhere they like as long as it is an authorised SharePoint location. Figure: Grant access for your TFS 2010 server to create sites in SharePoint 2010 Now that we have an authorised location for our team project portals to be created we need to tell our Team Project Collection that this is where it should stick sites by default for any new Team Projects created. Configure the Team Foundation Server 2010 Team Project Collection to create new sites in SharePoint 2010 Back on out TFS 2010 server we need to setup the defaults for our upgraded Team Project Collection to the new SharePoint 2010 integration we have just set up. On the TFS 2010 server open up the “Team Foundation Server Administration Console” again and navigate to the “Team Project Collections” node. Once you are there you will see a list of all of your TPC’s and in our case we have a DefaultCollection as well as out named and Upgraded collection for TFS 2008. If you select the “SharePoint Site” tab we can see that it is not currently configured. Figure: Our new Upgrade TFS2008 Team Project Collection does not have SharePoint configured Select to “Edit Default Site Location” and select the new integration point that we just set up for SharePoint 2010. Once you have selected the “SharePoint Web Application” (the thing we just configured) then it will give you an example based on that configuration point and the name of the Team Project Collection that we are configuring. Figure: Set the default location for new Team Project Portals to be created for this Team Project Collection This is where the reason for configuring the Extensions on the SharePoint 2010 server before doing this last bit becomes apparent. TFS 2010 is going to create a site at our http://sharepointserver/tfs02/ location called http://sharepointserver/tfs02/[TeamProjectCollection], or whatever we had specified, and it would have had difficulty doing this if we had not given it permission first. Figure: If there is no Team Project Collection site at this location the TFS 2010 server is going to create one This will create a nice Team Project Collection parent site to contain the Portals for any new Team Projects that are created. It is with noting that it will not create portals for existing Team Projects as this process is run during the Team Project Creation wizard. Figure: Just a basic parent site to host all of your new Team Project Portals as sub sites   You will need to add all of the users that will be creating Team Projects to be Administrators of this site so that they will not get an error during the Project Creation Wizard. You may also want to customise this as a proper portal to your projects if you are going to be having lots of them, but it is really just a default placeholder so you have a top level site that you can backup and point at. You have now integrated SharePoint 2010 and team Foundation Server 2010! You can now go forth and multiple your Team Projects for this Team Project Collection or you can continue to add portals to your other Collections.   Technorati Tags: TFS 2010,Sharepoint 2010,VS ALM

• Parallelism in .NET – Part 14, The Different Forms of Task

  - by Reed

  Before discussing Task creation and actual usage in concurrent environments, I will briefly expand upon my introduction of the Task class and provide a short explanation of the distinct forms of Task.  The Task Parallel Library includes four distinct, though related, variations on the Task class. In my introduction to the Task class, I focused on the most basic version of Task.  This version of Task, the standard Task class, is most often used with an Action delegate.  This allows you to implement for each task within the task decomposition as a single delegate. Typically, when using the new threading constructs in .NET 4 and the Task Parallel Library, we use lambda expressions to define anonymous methods.  The advantage of using a lambda expression is that it allows the Action delegate to directly use variables in the calling scope.  This eliminates the need to make separate Task classes for Action<T>, Action<T1,T2>, and all of the other Action<…> delegate types.  As an example, suppose we wanted to make a Task to handle the ”Show Splash” task from our earlier decomposition.  Even if this task required parameters, such as a message to display, we could still use an Action delegate specified via a lambda: // Store this as a local variable string messageForSplashScreen = GetSplashScreenMessage(); // Create our task Task showSplashTask = new Task( () => { // We can use variables in our outer scope, // as well as methods scoped to our class! this.DisplaySplashScreen(messageForSplashScreen); }); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } This provides a huge amount of flexibility.  We can use this single form of task for any task which performs an operation, provided the only information we need to track is whether the task has completed successfully or not.  This leads to my first observation: Use a Task with a System.Action delegate for any task for which no result is generated. This observation leads to an obvious corollary: we also need a way to define a task which generates a result.  The Task Parallel Library provides this via the Task<TResult> class. Task<TResult> subclasses the standard Task class, providing one additional feature – the ability to return a value back to the user of the task.  This is done by switching from providing an Action delegate to providing a Func<TResult> delegate.  If we decompose our problem, and we realize we have one task where its result is required by a future operation, this can be handled via Task<TResult>.  For example, suppose we want to make a task for our “Check for Update” task, we could do: Task<bool> checkForUpdateTask = new Task<bool>( () => { return this.CheckWebsiteForUpdate(); }); Later, we would start this task, and perform some other work.  At any point in the future, we could get the value from the Task<TResult>.Result property, which will cause our thread to block until the task has finished processing: // This uses Task<bool> checkForUpdateTask generated above... // Start the task, typically on a background thread checkForUpdateTask.Start(); // Do some other work on our current thread this.DoSomeWork(); // Discover, from our background task, whether an update is available // This will block until our task completes bool updateAvailable = checkForUpdateTask.Result; This leads me to my second observation: Use a Task<TResult> with a System.Func<TResult> delegate for any task which generates a result. Task and Task<TResult> provide a much cleaner alternative to the previous Asynchronous Programming design patterns in the .NET framework.  Instead of trying to implement IAsyncResult, and providing BeginXXX() and EndXXX() methods, implementing an asynchronous programming API can be as simple as creating a method that returns a Task or Task<TResult>.  The client side of the pattern also is dramatically simplified – the client can call a method, then either choose to call task.Wait() or use task.Result when it needs to wait for the operation’s completion. While this provides a much cleaner model for future APIs, there is quite a bit of infrastructure built around the current Asynchronous Programming design patterns.  In order to provide a model to work with existing APIs, two other forms of Task exist.  There is a constructor for Task which takes an Action<Object> and a state parameter.  In addition, there is a constructor for creating a Task<TResult> which takes a Func<Object, TResult> as well as a state parameter.  When using these constructors, the state parameter is stored in the Task.AsyncState property. While these two overloads exist, and are usable directly, I strongly recommend avoiding this for new development.  The two forms of Task which take an object state parameter exist primarily for interoperability with traditional .NET Asynchronous Programming methodologies.  Using lambda expressions to capture variables from the scope of the creator is a much cleaner approach than using the untyped state parameters, since lambda expressions provide full type safety without introducing new variables.

• Metro: Introduction to CSS 3 Grid Layout

  - by Stephen.Walther

  The purpose of this blog post is to provide you with a quick introduction to the new W3C CSS 3 Grid Layout standard. You can use CSS Grid Layout in Metro style applications written with JavaScript to lay out the content of an HTML page. CSS Grid Layout provides you with all of the benefits of using HTML tables for layout without requiring you to actually use any HTML table elements. Doing Page Layouts without Tables Back in the 1990’s, if you wanted to create a fancy website, then you would use HTML tables for layout. For example, if you wanted to create a standard three-column page layout then you would create an HTML table with three columns like this: <table height="100%"> <tr> <td valign="top" width="300px" bgcolor="red"> Left Column, Left Column, Left Column, Left Column, Left Column, Left Column, Left Column, Left Column, Left Column </td> <td valign="top" bgcolor="green"> Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column </td> <td valign="top" width="300px" bgcolor="blue"> Right Column, Right Column, Right Column, Right Column, Right Column, Right Column, Right Column, Right Column, Right Column </td> </tr> </table> When the table above gets rendered out to a browser, you end up with the following three-column layout: The width of the left and right columns is fixed – the width of the middle column expands or contracts depending on the width of the browser. Sometime around the year 2005, everyone decided that using tables for layout was a bad idea. Instead of using tables for layout — it was collectively decided by the spirit of the Web — you should use Cascading Style Sheets instead. Why is using HTML tables for layout bad? Using tables for layout breaks the semantics of the TABLE element. A TABLE element should be used only for displaying tabular information such as train schedules or moon phases. Using tables for layout is bad for accessibility (The Web Content Accessibility Guidelines 1.0 is explicit about this) and using tables for layout is bad for separating content from layout (see http://CSSZenGarden.com). Post 2005, anyone who used HTML tables for layout were encouraged to hold their heads down in shame. That’s all well and good, but the problem with using CSS for layout is that it can be more difficult to work with CSS than HTML tables. For example, to achieve a standard three-column layout, you either need to use absolute positioning or floats. Here’s a three-column layout with floats: <style type="text/css"> #container { min-width: 800px; } #leftColumn { float: left; width: 300px; height: 100%; background-color:red; } #middleColumn { background-color:green; height: 100%; } #rightColumn { float: right; width: 300px; height: 100%; background-color:blue; } </style> <div id="container"> <div id="rightColumn"> Right Column, Right Column, Right Column, Right Column, Right Column, Right Column, Right Column, Right Column, Right Column </div> <div id="leftColumn"> Left Column, Left Column, Left Column, Left Column, Left Column, Left Column, Left Column, Left Column, Left Column </div> <div id="middleColumn"> Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column </div> </div> The page above contains four DIV elements: a container DIV which contains a leftColumn, middleColumn, and rightColumn DIV. The leftColumn DIV element is floated to the left and the rightColumn DIV element is floated to the right. Notice that the rightColumn DIV appears in the page before the middleColumn DIV – this unintuitive ordering is necessary to get the floats to work correctly (see http://stackoverflow.com/questions/533607/css-three-column-layout-problem). The page above (almost) works with the most recent versions of most browsers. For example, you get the correct three-column layout in both Firefox and Chrome: And the layout mostly works with Internet Explorer 9 except for the fact that for some strange reason the min-width doesn’t work so when you shrink the width of your browser, you can get the following unwanted layout: Notice how the middle column (the green column) bleeds to the left and right. People have solved these issues with more complicated CSS. For example, see: http://matthewjamestaylor.com/blog/holy-grail-no-quirks-mode.htm But, at this point, no one could argue that using CSS is easier or more intuitive than tables. It takes work to get a layout with CSS and we know that we could achieve the same layout more easily using HTML tables. Using CSS Grid Layout CSS Grid Layout is a new W3C standard which provides you with all of the benefits of using HTML tables for layout without the disadvantage of using an HTML TABLE element. In other words, CSS Grid Layout enables you to perform table layouts using pure Cascading Style Sheets. The CSS Grid Layout standard is still in a “Working Draft” state (it is not finalized) and it is located here: http://www.w3.org/TR/css3-grid-layout/ The CSS Grid Layout standard is only supported by Internet Explorer 10 and there are no signs that any browser other than Internet Explorer will support this standard in the near future. This means that it is only practical to take advantage of CSS Grid Layout when building Metro style applications with JavaScript. Here’s how you can create a standard three-column layout using a CSS Grid Layout: <!DOCTYPE html> <html> <head> <style type="text/css"> html, body, #container { height: 100%; padding: 0px; margin: 0px; } #container { display: -ms-grid; -ms-grid-columns: 300px auto 300px; -ms-grid-rows: 100%; } #leftColumn { -ms-grid-column: 1; background-color:red; } #middleColumn { -ms-grid-column: 2; background-color:green; } #rightColumn { -ms-grid-column: 3; background-color:blue; } </style> </head> <body> <div id="container"> <div id="leftColumn"> Left Column, Left Column, Left Column, Left Column, Left Column, Left Column, Left Column, Left Column, Left Column </div> <div id="middleColumn"> Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column </div> <div id="rightColumn"> Right Column, Right Column, Right Column, Right Column, Right Column, Right Column, Right Column, Right Column, Right Column </div> </div> </body> </html> When the page above is rendered in Internet Explorer 10, you get a standard three-column layout: The page above contains four DIV elements: a container DIV which contains a leftColumn DIV, middleColumn DIV, and rightColumn DIV. The container DIV is set to Grid display mode with the following CSS rule: #container { display: -ms-grid; -ms-grid-columns: 300px auto 300px; -ms-grid-rows: 100%; } The display property is set to the value “-ms-grid”. This property causes the container DIV to lay out its child elements in a grid. (Notice that you use “-ms-grid” instead of “grid”. The “-ms-“ prefix is used because the CSS Grid Layout standard is still preliminary. This implementation only works with IE10 and it might change before the final release.) The grid columns and rows are defined with the “-ms-grid-columns” and “-ms-grid-rows” properties. The style rule above creates a grid with three columns and one row. The left and right columns are fixed sized at 300 pixels. The middle column sizes automatically depending on the remaining space available. The leftColumn, middleColumn, and rightColumn DIVs are positioned within the container grid element with the following CSS rules: #leftColumn { -ms-grid-column: 1; background-color:red; } #middleColumn { -ms-grid-column: 2; background-color:green; } #rightColumn { -ms-grid-column: 3; background-color:blue; } The “-ms-grid-column” property is used to specify the column associated with the element selected by the style sheet selector. The leftColumn DIV is positioned in the first grid column, the middleColumn DIV is positioned in the second grid column, and the rightColumn DIV is positioned in the third grid column. I find using CSS Grid Layout to be just as intuitive as using an HTML table for layout. You define your columns and rows and then you position different elements within these columns and rows. Very straightforward. Creating Multiple Columns and Rows In the previous section, we created a super simple three-column layout. This layout contained only a single row. In this section, let’s create a slightly more complicated layout which contains more than one row: The following page contains a header row, a content row, and a footer row. The content row contains three columns: <!DOCTYPE html> <html> <head> <style type="text/css"> html, body, #container { height: 100%; padding: 0px; margin: 0px; } #container { display: -ms-grid; -ms-grid-columns: 300px auto 300px; -ms-grid-rows: 100px 1fr 100px; } #header { -ms-grid-column: 1; -ms-grid-column-span: 3; -ms-grid-row: 1; background-color: yellow; } #leftColumn { -ms-grid-column: 1; -ms-grid-row: 2; background-color:red; } #middleColumn { -ms-grid-column: 2; -ms-grid-row: 2; background-color:green; } #rightColumn { -ms-grid-column: 3; -ms-grid-row: 2; background-color:blue; } #footer { -ms-grid-column: 1; -ms-grid-column-span: 3; -ms-grid-row: 3; background-color: orange; } </style> </head> <body> <div id="container"> <div id="header"> Header, Header, Header </div> <div id="leftColumn"> Left Column, Left Column, Left Column, Left Column, Left Column, Left Column, Left Column, Left Column, Left Column </div> <div id="middleColumn"> Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column, Middle Column </div> <div id="rightColumn"> Right Column, Right Column, Right Column, Right Column, Right Column, Right Column, Right Column, Right Column, Right Column </div> <div id="footer"> Footer, Footer, Footer </div> </div> </body> </html> In the page above, the grid layout is created with the following rule which creates a grid with three rows and three columns: #container { display: -ms-grid; -ms-grid-columns: 300px auto 300px; -ms-grid-rows: 100px 1fr 100px; } The header is created with the following rule: #header { -ms-grid-column: 1; -ms-grid-column-span: 3; -ms-grid-row: 1; background-color: yellow; } The header is positioned in column 1 and row 1. Furthermore, notice that the “-ms-grid-column-span” property is used to span the header across three columns. CSS Grid Layout and Fractional Units When you use CSS Grid Layout, you can take advantage of fractional units. Fractional units provide you with an easy way of dividing up remaining space in a page. Imagine, for example, that you want to create a three-column page layout. You want the size of the first column to be fixed at 200 pixels and you want to divide the remaining space among the remaining three columns. The width of the second column is equal to the combined width of the third and fourth columns. The following CSS rule creates four columns with the desired widths: #container { display: -ms-grid; -ms-grid-columns: 200px 2fr 1fr 1fr; -ms-grid-rows: 1fr; } The fr unit represents a fraction. The grid above contains four columns. The second column is two times the size (2fr) of the third (1fr) and fourth (1fr) columns. When you use the fractional unit, the remaining space is divided up using fractional amounts. Notice that the single row is set to a height of 1fr. The single grid row gobbles up the entire vertical space. Here’s the entire HTML page: <!DOCTYPE html> <html> <head> <style type="text/css"> html, body, #container { height: 100%; padding: 0px; margin: 0px; } #container { display: -ms-grid; -ms-grid-columns: 200px 2fr 1fr 1fr; -ms-grid-rows: 1fr; } #firstColumn { -ms-grid-column: 1; background-color:red; } #secondColumn { -ms-grid-column: 2; background-color:green; } #thirdColumn { -ms-grid-column: 3; background-color:blue; } #fourthColumn { -ms-grid-column: 4; background-color:orange; } </style> </head> <body> <div id="container"> <div id="firstColumn"> First Column, First Column, First Column </div> <div id="secondColumn"> Second Column, Second Column, Second Column </div> <div id="thirdColumn"> Third Column, Third Column, Third Column </div> <div id="fourthColumn"> Fourth Column, Fourth Column, Fourth Column </div> </div> </body> </html>   Summary There is more in the CSS 3 Grid Layout standard than discussed in this blog post. My goal was to describe the basics. If you want to learn more than you can read through the entire standard at http://www.w3.org/TR/css3-grid-layout/ In this blog post, I described some of the difficulties that you might encounter when attempting to replace HTML tables with Cascading Style Sheets when laying out a web page. I explained how you can take advantage of the CSS 3 Grid Layout standard to avoid these problems when building Metro style applications using JavaScript. CSS 3 Grid Layout provides you with all of the benefits of using HTML tables for laying out a page without requiring you to use HTML table elements.
