  • Why is my computer using so much ram?

    - by Ian
    I have 16gb of ram installed in my computer, and nearly 70% of it is used at all times. Looking at the processes in task manager the memory being used with everything in there doesn't even add up to 2gb. I have RAPID mode enabled on my ssd which may be using 2gb at most so I would understand that. I am thinking there might be a memory leak somewhere, but I don't really know how I would be able to tell. My performance and process list is below:

  • Email server - Disk quota sizes - suggestions?

    - by Ian H
    Working out a new server for an agency of 200 Employees - with approx 240 email accounts. Internally I'm arguing with myself over the amount of drive space to allocate to each user for the disk quota, I'm just looking for suggestions. Once i have a quota size decided, it will define the solution for storage. I've had everything from 4 GB per account ( which i feel is being generous ) down to 500 Mb ( with is rather restrictive in today's day and age. ) Thing is 4 GB per acocunt is just under 1 TB of allocated storage for email alone. Does anyone follow a "rule of thumb" or have thoughts on this? thanks in advance

  • stopping fastcgi_cache for php-enabled custom error page

    - by Ian
    Since enabling the fastcgi_cache on my nginx server, my php-enabled custom error page has suddenly stopped working and I'm getting the internal 404 message instead. In nginx.conf: fastcgi_cache_path /var/lib/nginx/fastcgicache levels=1:2 keys_zone=MYCACHE:5m inactive=2h max_size=1g loader_files=1000 loader_threshold=2000; map $http_cookie $no_cache { default 0; ~SESS 1; } fastcgi_cache_key "$scheme$request_method$host$request_uri"; add_header X-My-Cache $upstream_cache_status; map $uri $no_cache_dirs { default 0; ~^/(?:phpMyAdmin|rather|poll|webmail|skewed|blogs|galleries|pixcache) 1; } the cache relevant stuff in my fastcgi.conf: fastcgi_cache MYCACHE; fastcgi_keep_conn on; fastcgi_cache_bypass $no_cache $no_cache_dirs; fastcgi_no_cache $no_cache $no_cache_dirs; fastcgi_cache_valid 200 301 5m; fastcgi_cache_valid 302 5m; fastcgi_cache_valid 404 1m; fastcgi_cache_use_stale error timeout invalid_header updating http_500; fastcgi_ignore_headers Cache-Control Expires; expires epoch; fastcgi_cache_lock on; If I disable the fastcgi_cache, the php-enabled 404 page works as it has for years. How would I disable the cache for the custom error page?

  • Cost of running colour laser printers.

    - by Ian Ringrose
    Has anyone got a good list of the costs of running colour laser printers, both for colour and black that take into account different usage volumes. E.g if the dram needs replacing after 20,000 pages, but I am only do 10,000 in the next 3 years, I don’t care about the cost of a new dram. So a simple “cost per page” figure is each printer is not good enough to be useful in real life. (A spread sheet / website that I could type my own usage values into would be great.)

  • How can I cut a line in TextWrangler?

    - by Ian Henry
    Trying out TextWrangler since my TextMate trial is about to expire and I'm not sure it's worth the cash to keep using it. The main thing I'm missing is the ability to cut the entire line that the cursor is on without having to select it (which I could accomplish through a TextMate macro). Yeah, I can hit ?L ?X, but I'd like to map this sequence to ^X so I can do it purely with my left hand. Seems like this should be easy, but it's beyond me. What's the best way to get this functionality?

  • How do I do a mail merge that includes images? (Maybe in Word 2007)

    - by Ian Ringrose
    I am trying to find out the practicalities of doing a mail merge when each “record” to be merged on includes some images. I need to: print letters And envelopes Both the letters and the envelopes have: Fixed text Fixed images Text that come from the mail merge record Images that come from the mail merge record I don’t know if all images will be the same size for every record, so a bit of simple “on the fly” automatic formatting may be needed . I need to be able to repeat a single item if I get a problem (e.g when folding the letter). What problems am I likely to have? Is Word 2007 up to this sort of mail merging, or should I be looking at a report writing tool? How do I restart a print run after a printer jam etc? What format should I store the “records” and there images in? E.g Can standard software cope with images that are stored in separate files named after the “CustomerId” that is in the “record” (I can write custom software if needed, but would rather use standard “of-the-shelf” software for the printing, I am planning on custom software for the data creation, so can output in whatever format is needed)

  • Lookups targeting merged cells - only returning value for first row

    - by Ian
    I have a master worksheet which contains data that I wish to link to another 'summary' sheet using a lookup. However, some of the cells whose data I wish to include in the summary sheet are merged across two or more adjacent rows. To be clear, the 'primary' column A that I am using in my formula in order to identify the target row does not contain merged cells, but the column from which I wish to return a value does. I have tried VLOOKUP and INDEX+MATCH. The problem is that the data is only returned for the first row's key, and the others return zero (as though the cell in the target column were blank, where actually it is merged). I have tried inelegant ways around this, e.g. using IF statements to try to find the top row of the merged cell. However, these don't work well if the order of values in the summary sheet is different from that in the master sheet, as well as being messy. Can this be done?

  • Giving Users Full Control of their local drives?

    - by Ian Bowes
    Is there a way to give a domain user full control of their local drives at the Group Policy end? Specifically, my IT Manager wants the following: a) Desktop control allowed b) Full access to local hard drives c) Software Installation NOT Allowed d) Existing software Updates Allowed e) Install additional printers Allowed At the moment, our Win2003 setup does not allow users to do a,b,d,e - I wondered if there was a way using GP to enable these?

  • Can you resize all mac windows at once? (e.g. when docking)

    - by Ian Varley
    I've recently bought a Henge Dock, and like the ability to plug my MacBook in and instantly reconnect to all my peripherals (external monitor, keyboard, mouse, etc.). The only problem is that when I dock or undock, all of my windows are left at the wrong size (either too big or too small) and I have to manually resize them, one by one. Not the end of the world, but ... isn't there an easier way? I've seen Cinch and Sizeup, but they seem to only work on one window (the current app). I looked at the Automator as a possible way to do this, but it didn't seem to have any window operations. I also tried the AppleScript listed here, but it put the windows in wacky places.

  • How can I open a port in OS X 10.6?

    - by Ian
    Mine is MacBook Air, so I cannot plug to the modem directly. And I do want to turn my firewall off. How can I specify to open a port, like port 56789 in Mac OS 10.6.8? I know in old Mac OS, there is a option for me to specify a custom port. But I cannot find it in OS X 10.6.8. In System Preferences / Security / Firewall, I only can allow an APPLICATION to access a new port. However, now I'm programming, using a new port. So, it seems not suitable for me. So, can I simply open a port instead of using an Application to open a port?

  • OpenSolaris / Nexenta problems with NetXen 4-port NIC card (ntxn driver)

    - by ewwhite
    Hello, I'm running NexentaStor Enterprise on an HP ProLiant DL180 G6 server. The onboard NIC interfaces surface as igb0 and igb1 and work well. However, I've added an HP NC375T 4-port network card using the NetXen 3031 chipset. This card should be handled by the ntxn driver in the SUNWntxn package, but that results in "ntxn0: failed to map doorbell" messages upon boot. The network interfaces don't show up. After some research, I found HP's driver package for the card. The release notes for the driver package state: This version of the Driver is supported only on Oracle Solaris 10 5/09 & 10/09. Oracle Solaris 10 5/09 & 10/09 contain an older version of NetXen P3 driver package called SUNWntxn. So, adding another version of NetXen P3 driver package using pkgadd command might result in conflicts with the NetXen driver binary & related files. Users are advised to uninstall native SUNWntxn driver package before installing the new package. The install completes, but I end up with a different set of errors in initializing the card. ifconfig ntxn0 plumb ifconfig: cannot open link "ntxn0": DLPI link does not exist dmesg output: Jan 29 07:20:17 ch-san2 ntxn: [ID 977263 kern.warning] WARNING: Memory not available Jan 29 07:20:17 ch-san2 ntxn: [ID 404858 kern.notice] NOTICE: ntxn0: Mac registration error Trying to manually create the device files: root@ch-san2:/volumes# add_drv -i "4040,100" ntxn ("ntxn") already in use as a driver or alias. Update the driver: root@ch-san2:/volumes# update_drv -f ntxn devfsadm: driver failed to attach: ntxn Warning: Driver (ntxn) successfully added to system but failed to attach Any ideas on how to get this driver working, or should I ditch the card and go with an Intel or something else?

  • conflicting info about the running kernel version in FreeBSD

    - by John
    I asked a related question about uname before, now want to ask from another angle because the following simple yet obvious conflicting outputs may mean there is something many people did not think of (me included). I'm running FreeBSD 9 RELEASE, please see the following commands: # sysctl kern.bootfile kern.bootfile: /boot/kernel/kernel # strings /boot/kernel/kernel |grep RELEASE|grep 9 @(#)FreeBSD 9.2-RELEASE-p7 #0: Tue Jun 3 11:05:13 UTC 2014 FreeBSD 9.2-RELEASE-p7 #0: Tue Jun 3 11:05:13 UTC 2014 9.2-RELEASE-p7 The above kernel file suggests the running kernel is 9.2-RELEASE-p7. But... # dmesg Copyright (c) 1992-2012 The FreeBSD Project. Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 The Regents of the University of California. All rights reserved. FreeBSD is a registered trademark of The FreeBSD Foundation. FreeBSD 9.1-RELEASE #0 r243825: Tue Dec 4 09:23:10 UTC 2012 ... # uname -a FreeBSD localhost.localdomain 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243825: Tue Dec 4 09:23:10 UTC 2012 [email protected]:/usr/obj/usr/src/sys/GENERIC amd64 So dmesg and uname says it's 9.1-RELEASE. I also did an extensive find / -type f -exec grep -l "9.1-RELEASE" {} \; but found no possible kernel file that contains 9.1-RELEASE. What could lead to the above conflict, and what kernel I am actually running? Please note I run RELEASE and ran freebsd-update to do binary update, so no compiled kernel is involved. And I have rebooted multiple times after freebsd-update. And the system is not in jail etc, just the only system on that computer.

  • logrotate deletes all maillogs older than one day

    - by shadyabhi
    I see only two files maillog and maillog.1 in /var/log. grepping for maillog in logrotate.d directory gives three files that have a mention of maillog. syslog /var/log/messages /var/log/secure /var/log/maillog /var/log/spooler /var/log/boot.log /var/log/cron { #/var/log/messages /var/log/secure /var/log/spooler /var/log/boot.log /var/log/cron { daily sharedscripts postrotate /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true /bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true endscript } syslog-ng /var/log/messages /var/log/secure /var/log/maillog /var/log/spooler /var/log/boot.log /var/log/cron /var/log/kern.log /var/log/kern { sharedscripts postrotate /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true /bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true endscript } and maillog. /var/log/maillog { daily compress # rotate 365 rotate 14 sharedscripts postrotate /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true /bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true endscript } I am new to logrotate so may be I am missing something obvious. What can be the issue? The setup was already done when I started managing the server so I don't also know as do why do I have 3 mentions for maillog in logrotate.

  • Scrolling an HTML 5 page using JQuery

    - by nikolaosk
    In this post I will show you how to use JQuery to scroll through an HTML 5 page.I had to help a friend of mine to implement this functionality and I thought it would be a good idea to write a post.I will not use any JQuery scrollbar plugin,I will just use the very popular JQuery Library. Please download the library (minified version) from http://jquery.com/download.Please find here all my posts regarding JQuery.Also have a look at my posts regarding HTML 5.In order to be absolutely clear this is not (and could not be) a detailed tutorial on HTML 5. There are other great resources for that.Navigate to the excellent interactive tutorials of W3School.Another excellent resource is HTML 5 Doctor.Two very nice sites that show you what features and specifications are implemented by various browsers and their versions are http://caniuse.com/ and http://html5test.com/. At this times Chrome seems to support most of HTML 5 specifications.Another excellent way to find out if the browser supports HTML 5 and CSS 3 features is to use the Javascript lightweight library Modernizr.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here. Let me move on to the actual example.This is the sample HTML 5 page<!DOCTYPE html><html lang="en">  <head>    <title>Liverpool Legends</title>        <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >        <link rel="stylesheet" type="text/css" href="style.css">        <script type="text/javascript" src="jquery-1.8.2.min.js"> </script>     <script type="text/javascript" src="scroll.js">     </script>       </head>  <body>    <header>        <h1>Liverpool Legends</h1>    </header>        <div id="main">        <table>        <caption>Liverpool Players</caption>        <thead>            <tr>                <th>Name</th>                <th>Photo</th>                <th>Position</th>                <th>Age</th>                <th>Scroll</th>            </tr>        </thead>        <tfoot class="footnote">            <tr>                <td colspan="4">We will add more photos soon</td>            </tr>        </tfoot>    <tbody>        <tr class="maintop">        <td>Alan Hansen</td>            <td>            <figure>            <img src="images\Alan-hansen-large.jpg" alt="Alan Hansen">            <figcaption>The best Liverpool Defender <a href="http://en.wikipedia.org/wiki/Alan_Hansen">Alan Hansen</a></figcaption>            </figure>            </td>            <td>Defender</td>            <td>57</td>            <td class="top">Middle</td>        </tr>        <tr>        <td>Graeme Souness</td>            <td>            <figure>            <img src="images\graeme-souness-large.jpg" alt="Graeme Souness">            <figcaption>Souness was the captain of the successful Liverpool team of the early 1980s <a href="http://en.wikipedia.org/wiki/Graeme_Souness">Graeme Souness</a></figcaption>            </figure>            </td>            <td>MidFielder</td>            <td>59</td>        </tr>        <tr>        <td>Ian Rush</td>            <td>            <figure>            <img src="images\ian-rush-large.jpg" alt="Ian Rush">            <figcaption>The deadliest Liverpool Striker <a href="http://it.wikipedia.org/wiki/Ian_Rush">Ian Rush</a></figcaption>            </figure>            </td>            <td>Striker</td>            <td>51</td>        </tr>        <tr class="mainmiddle">        <td>John Barnes</td>            <td>            <figure>            <img src="images\john-barnes-large.jpg" alt="John Barnes">            <figcaption>The best Liverpool Defender <a href="http://en.wikipedia.org/wiki/John_Barnes_(footballer)">John Barnes</a></figcaption>            </figure>            </td>            <td>MidFielder</td>            <td>49</td>            <td class="middle">Bottom</td>        </tr>                <tr>        <td>Kenny Dalglish</td>            <td>            <figure>            <img src="images\kenny-dalglish-large.jpg" alt="Kenny Dalglish">            <figcaption>King Kenny <a href="http://en.wikipedia.org/wiki/Kenny_Dalglish">Kenny Dalglish</a></figcaption>            </figure>            </td>            <td>Midfielder</td>            <td>61</td>        </tr>        <tr>            <td>Michael Owen</td>            <td>            <figure>            <img src="images\michael-owen-large.jpg" alt="Michael Owen">            <figcaption>Michael was Liverpool's top goal scorer from 1997–2004 <a href="http://www.michaelowen.com/">Michael Owen</a></figcaption>            </figure>            </td>            <td>Striker</td>            <td>33</td>        </tr>        <tr>            <td>Robbie Fowler</td>            <td>            <figure>            <img src="images\robbie-fowler-large.jpg" alt="Robbie Fowler">            <figcaption>Fowler scored 183 goals in total for Liverpool <a href="http://en.wikipedia.org/wiki/Robbie_Fowler">Robbie Fowler</a></figcaption>            </figure>            </td>            <td>Striker</td>            <td>38</td>        </tr>        <tr class="mainbottom">            <td>Steven Gerrard</td>            <td>            <figure>            <img src="images\steven-gerrard-large.jpg" alt="Steven Gerrard">            <figcaption>Liverpool's captain <a href="http://en.wikipedia.org/wiki/Steven_Gerrard">Steven Gerrard</a></figcaption>            </figure>            </td>            <td>Midfielder</td>            <td>32</td>            <td class="bottom">Top</td>        </tr>    </tbody></table>          </div>            <footer>        <p>All Rights Reserved</p>      </footer>     </body>  </html>  The markup is very easy to follow and understand. You do not have to type all the code,simply copy and paste it.For those that you are not familiar with HTML 5, please take a closer look at the new tags/elements introduced with HTML 5.When I view the HTML 5 page with Firefox I see the following result. I have also an external stylesheet (style.css). body{background-color:#efefef;}h1{font-size:2.3em;}table { border-collapse: collapse;font-family: Futura, Arial, sans-serif; }caption { font-size: 1.2em; margin: 1em auto; }th, td {padding: .65em; }th, thead { background: #000; color: #fff; border: 1px solid #000; }tr:nth-child(odd) { background: #ccc; }tr:nth-child(even) { background: #404040; }td { border-right: 1px solid #777; }table { border: 1px solid #777;  }.top, .middle, .bottom {    cursor: pointer;    font-size: 22px;    font-weight: bold;    text-align: center;}.footnote{text-align:center;font-family:Tahoma;color:#EB7515;}a{color:#22577a;text-decoration:none;}     a:hover {color:#125949; text-decoration:none;}  footer{background-color:#505050;width:1150px;}These are just simple CSS Rules that style the various HTML 5 tags,classes. The jQuery code that makes it all possible resides inside the scroll.js file.Make sure you type everything correctly.$(document).ready(function() {                 $('.top').click(function(){                     $('html, body').animate({                         scrollTop: $(".mainmiddle").offset().top                     },4000 );                  });                 $('.middle').click(function(){                     $('html, body').animate({                         scrollTop: $(".mainbottom").offset().top                     },4000);                  });                     $('.bottom').click(function(){                     $('html, body').animate({                         scrollTop: $(".maintop").offset().top                     },4000);                  }); });  Let me explain what I am doing here.When I click on the Middle word (  $('.top').click(function(){ ) this relates to the top class that is clicked.Then we declare the elements that we want to participate in the scrolling. In this case is html,body ( $('html, body').animate).These elements will be part of the vertical scrolling.In the next line of code we simply move (navigate) to the element (class mainmiddle that is attached to a tr element.)      scrollTop: $(".mainmiddle").offset().top  Make sure you type all the code correctly and try it for yourself. I have tested this solution will all 4-5 major browsers.Hope it helps!!!

  • ExtJS RowEditor on Grid

    - by Ian Warner
    Hi When my users edits the Grid via RowEditor combo entries and checkboxes are annoying 1 Apple 2 Orange 3 Pear For instance with the combo above the user will select Orange then update - the Grid now instead of saying orange will display the number 2 - I would like it to show orange when a successful edit has been made. code for my combo editor : { allowBlank : false, displayField : 'team', editable : false, emptyText : 'Select Team', forceSelection : true, lazyRender : true, mode : 'remote', name : 'team', store : storeTeam, triggerAction : 'all', valueField : 'id', xtype : 'combo' } I think I read that you could send the complete row back to insert or I should listen to the update of the grid and then change the field but I need some guidance on what is best Cheers

  • jQuery autocomplete - update options on dynamically created elements

    - by Ian Robinson
    Background The user enters values into multiple inputs on the page. Think of entering a list of widgets for sale. The user would select the type of a widget from a drop down. Then enter the name of the Widget vendor, and then the actual name of the widget. These UI elements would all appear as one row. The user is able to click an "add another widget" link and a new row is created. The two input elements have autocomplete functionality attached to them using the DevBridge jQuery plugin. It suggests the name of the vendor and the name of the widget. I have recently wired up the logic to filter the name of the widget based on the name of the vendor you entered. This means setting the (custom) vendorName parameter when attaching the autocomplete plugin so it can be passed to the server side to retrieve the widget names for that vendor that match the name the user entered. To achieve this functionality I'm dynamically attaching the autocomplete functionality to the second element (the widget name text box) when it receives focus. Here is an example: $('.autocomplete-widget').live('focus', function () { $(this).autocomplete({ serviceUrl: '/something.ashx', params: { type: 'widget', vendorName: $(this).parent().prev().find('.autocomplete-vendor').val()} }); }); Problem At first glance, this looks to function quite well. However I started noticing some inconsistencies, and upon inspection, I found out that the call to the server is actually happening several times in some cases. Each time the widget name input element receives focus the autocomplete functionality is attached. And what I'm seeing is that the call to the server is made in proportion to how many times the input element has gained focus. I'd like to avoid making the call more than once, but retain the ability to attach (or update) the autocomplete functionality "on focus". I've tried to use the autocomplete 'setOptions' method but have only been able to get it to work with the static elements, not the dynamically created elements. Question Is there a way I can clear out the autocomplete functionality before I attach another one?

  • ASP.Net MVC2 CustomModelBinder not working... Changed from MVC1

    - by Ian
    (My apologies if this seems verbose - trying to provide all relevant code) I've just upgraded to VS2010, and am now having trouble trying to get a new CustomModelBinder working. In MVC1 I would have written something like public class AwardModelBinder: DefaultModelBinder { : public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { // do the base binding to bind all simple types Award award = base.BindModel(controllerContext, bindingContext) as Award; // Get complex values from ValueProvider dictionary award.EffectiveFrom = Convert.ToDateTime(bindingContext.ValueProvider["Model.EffectiveFrom"].AttemptedValue.ToString()); string sEffectiveTo = bindingContext.ValueProvider["Model.EffectiveTo"].AttemptedValue.ToString(); if (sEffectiveTo.Length > 0) award.EffectiveTo = Convert.ToDateTime(bindingContext.ValueProvider["Model.EffectiveTo"].AttemptedValue.ToString()); // etc return award; } } Of course I'd register the custom binder in Global.asax.cs: protected void Application_Start() { RegisterRoutes(RouteTable.Routes); // register custom model binders ModelBinders.Binders.Add(typeof(Voucher), new VoucherModelBinder(DaoFactory.UserInstance("EH1303"))); ModelBinders.Binders.Add(typeof(AwardCriterion), new AwardCriterionModelBinder(DaoFactory.UserInstance("EH1303"), new VOPSDaoFactory())); ModelBinders.Binders.Add(typeof(SelectedVoucher), new SelectedVoucherModelBinder(DaoFactory.UserInstance("IT0706B"))); ModelBinders.Binders.Add(typeof(Award), new AwardModelBinder(DaoFactory.UserInstance("IT0706B"))); } Now, in MVC2, I'm finding that my call to base.BindModel returns an object where everything is null, and I simply don't want to have to iterate all the form fields surfaced by the new ValueProvider.GetValue() function. Google finds no matches for this error, so I assume I'm doing something wrong. Here's my actual code: My domain object (infer what you like about the encapsulated child objects - I know I'll need custom binders for those too, but the three "simple" fields (ie. base types) Id, TradingName and BusinessIncorporated are also coming back null): public class Customer { /// <summary> /// Initializes a new instance of the Customer class. /// </summary> public Customer() { Applicant = new Person(); Contact = new Person(); BusinessContact = new ContactDetails(); BankAccount = new BankAccount(); } /// <summary> /// Gets or sets the unique customer identifier. /// </summary> public int Id { get; set; } /// <summary> /// Gets or sets the applicant details. /// </summary> public Person Applicant { get; set; } /// <summary> /// Gets or sets the customer's secondary contact. /// </summary> public Person Contact { get; set; } /// <summary> /// Gets or sets the trading name of the business. /// </summary> [Required(ErrorMessage = "Please enter your Business or Trading Name")] [StringLength(50, ErrorMessage = "A maximum of 50 characters is permitted")] public string TradingName { get; set; } /// <summary> /// Gets or sets the date the customer's business began trading. /// </summary> [Required(ErrorMessage = "You must supply the date your business started trading")] [DateRange("01/01/1900", "01/01/2020", ErrorMessage = "This date must be between {0} and {1}")] public DateTime BusinessIncorporated { get; set; } /// <summary> /// Gets or sets the contact details for the customer's business. /// </summary> public ContactDetails BusinessContact { get; set; } /// <summary> /// Gets or sets the customer's bank account details. /// </summary> public BankAccount BankAccount { get; set; } } My controller method: /// <summary> /// Saves a Customer object from the submitted application form. /// </summary> /// <param name="customer">A populate instance of the Customer class.</param> /// <returns>A partial view indicating success or failure.</returns> /// <httpmethod>POST</httpmethod> /// <url>/Customer/RegisterCustomerAccount</url> [HttpPost] [ValidateAntiForgeryToken] public ActionResult RegisterCustomerAccount(Customer customer) { if (ModelState.IsValid) { // save the Customer // return indication of success, or otherwise return PartialView(); } else { ViewData.Model = customer; // load necessary reference data into ViewData ViewData["PersonTitles"] = new SelectList(ReferenceDataCache.Get("PersonTitle"), "Id", "Name"); return PartialView("CustomerAccountRegistration", customer); } } My custom binder: public class CustomerModelBinder : DefaultModelBinder { public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { ValueProviderResult vpResult = bindingContext .ValueProvider.GetValue(bindingContext.ModelName); // vpResult is null // MVC2 - ValueProvider is now an IValueProvider, not dictionary based anymore if (bindingContext.ValueProvider.GetValue("Model.Applicant.Title") != null) { // works } Customer customer = base.BindModel(controllerContext, bindingContext) as Customer; // customer instanitated with null (etc) throughout return customer; } } My binder registration: /// <summary> /// Application_Start is called once when the web application is first accessed. /// </summary> protected void Application_Start() { RegisterRoutes(RouteTable.Routes); // register custom model binders ModelBinders.Binders.Add(typeof(Customer), new CustomerModelBinder()); ReferenceDataCache.Populate(); } ... and a snippet from my view (could this be a prefix problem?) <div class="inputContainer"> <label class="above" for="Model_Applicant_Title" accesskey="t"><span class="accesskey">T</span>itle<span class="mandatoryfield">*</span></label> <%= Html.DropDownList("Model.Applicant.Title", ViewData["PersonTitles"] as SelectList, "Select ...", new { @class = "validate[required]" })%> <% Html.ValidationMessageFor(model => model.Applicant.Title); %> </div> <div class="inputContainer"> <label class="above" for="Model_Applicant_Forename" accesskey="f"><span class="accesskey">F</span>orename / First name<span class="mandatoryfield">*</span></label> <%= Html.TextBox("Model.Applicant.Forename", Html.Encode(Model.Applicant.Forename), new { @class = "validate[required,custom[onlyLetter],length[2,20]]", title="Enter your forename", maxlength = 20, size = 20, autocomplete = "off", onkeypress = "return maskInput(event,re_mask_alpha);" })%> </div> <div class="inputContainer"> <label class="above" for="Model_Applicant_MiddleInitials" accesskey="i">Middle <span class="accesskey">I</span>nitial(s)</label> <%= Html.TextBox("Model.Applicant.MiddleInitials", Html.Encode(Model.Applicant.MiddleInitials), new { @class = "validate[optional,custom[onlyLetter],length[0,8]]", title = "Please enter your middle initial(s)", maxlength = 8, size = 8, autocomplete = "off", onkeypress = "return maskInput(event,re_mask_alpha);" })%> </div>

  • A simple augmented reality application in C#

    - by Ian
    Hi All, I would like to start a personal project that will give me a lot of new concept to learn and understand. After some thought, I figured that an Augmented Reality related project will be the most beneficial for me because of the following reasons: I haven't tried interfacing a program with a live video/camera feed I haven't done any "image processing" project I haven't done any "graphics rendering" ever With that said, you can assume that I will totally suck at AR. So I'm here to ask for some advice regarding the best way to go through this. st milestone project that I am thinking of is to take a cheap webcam and read some Data Matrix using C#. nd milestone project will render some text-overlay on the feed when presented with a certain Data Matrix. rd milestone project will actually render some 3D shapes. I've searched all-around and found some nice yet advanced materials for AR: http://sites.google.com/site/augmentedrealitytestingsite/ http://soldeveloper.com/ http://www.mperfect.net/wpfAugReal/ So I came here to ask the following: Do you think my milestone is reasonable given my "deficiencies"? In order to start Milestone 1, can you give some materials that I can study? I prefer online materials. Thanks!

  • ASP.NET DataList - defining "columns/rows" when repeating horizontal and using flow layout

    - by Ian Robinson
    Here is my DataList: <asp:DataList id="DataList" Visible="false" RepeatDirection="Horizontal" Width="100%" HorizontalAlign="Justify" RepeatLayout="Flow" runat="server"> [Contents Removed] </asp:DataList> This generates markup that has each item wrapped in a span. From there, I'd like to break each of these spans out into rows of three columns. Ideally I would like something like this: <div> <span>Item 1</span> <span>Item 2</span> <span>Item 3</span> </div> <div> <span>Item 4</span> <span>Item 5</span> <span>Item 6</span> </div> [etc] The closest I can get to this is to set RepeatColumns to "3" and then a <br> is inserted after every three items in the DataList. <span>Item 1</span> <span>Item 2</span> <span>Item 3</span> <br> <span>Item 4</span> <span>Item 5</span> <span>Item 6</span> <br> This gets me kind of close, but really doesn't do the trick - I still can't control the layout the way I'd like to be able to. Can anyone suggest a way to make this better? If I could implement the above example - that would be perfect, however I'd accept a less elegant solution as well - as long as its more flexible than <br> (such as inserting a <span class="clear"></span> instead of <br>).
