  - by Dave Campbell

  In this Back from the Summit Issue, I am overloaded with posts to choose from. Submittals go first, but I'll eventually catch up... hopefully by MIX :) : Ollie Riches(-2-), Colin Eberhardt, John Papa, Jeremy Likness, Martin Krüger, Joost van Schaik, Karl Shifflett, Michael Crump, Georgi Stoyanov, Yochay Kiriaty, Page Brooks, and Deborah Kurata. Above the Fold: Silverlight: "ClassifiedCabinet: A Quick Start" Georgi Stoyanov WP7: "Easy access to WMAppManifest.xml App properties like version and title" Joost van Schaik Multiple: "Flashcards.Show Version 2 for the Desktop, Browser, and Windows Phone" Yochay Kiriaty Shoutouts: Mohamed Mosallem delivered an online session at the Second Riyadh Online Community Summit: Silverlight 4.0 with SharePoint 2010 John-Daniel Trask posted about a release of a new set of tools released for WP7 development... there's a free trial, so definitely worth a look: Mindscape Phone Elements released! From SilverlightCream.com: WP7Contrib: Trickling data to a bound collection Ollie Riches submitted a couple links... first up is this on a way they found to decrease the load on a data template in WP7 to get under the 90 mb limit and then added their solution to the WP7Contrib lib. WP7Contrib: Why we use SilverlightSerializer instead of DataContractSerializer Ollie Riches' next submittal compares the performance of the SilverlightSerializer & DataContractSerializer on the WP7 platform.

• Download YouTube Videos the Easy Way

  - by Trevor Bekolay

  You can’t be online all the time, and despite the majority of YouTube videos being nut-shots and Lady Gaga parodies, there is a lot of great content that you might want to download and watch offline. There are some programs and browser extensions to do this, but we’ve found that the easiest and quickest method is a bookmarklet that was originally posted on the Google Operating System blog (it’s since been removed). It will let you download standard quality and high-definition movies as MP4 files. Also, because it’s a bookmarklet, it will work on any modern web browser, and on any operating system! Installing the bookmarket is easy – just drag and drop the Get YouTube video link below to the bookmarks bar of your browser of choice. If you’ve hidden the bookmark bar, in most browsers you can right-click on the link and save it to your bookmarks. Get YouTube video   With the bookmarklet available in your browser, go to the YouTube video that you’d like to download. Click on the Get YouTube video link in your bookmarks bar, or in the bookmarks menu, wherever you saved it earlier. You will notice some new links appear below the description of the video. If you download the standard definition file, it will save as “video.mp4” by default. However, if you download the high definition file, it will save with the same name as the title of the video. There are many methods of downloading YouTube videos…but we think this is the easiest and quickest method. You don’t have to install anything or use up resources, but you can still get a link to download an MP4 with one click. Do you use a different method to download Youtube videos? Let us know about it in the comments! javascript:(function(){if(document.getElementById(’download-youtube-video’))return;var args=null,video_title=null,video_id=null,video_hash=null;var download_code=new Array();var fmt_labels={‘18′:’standard%20MP4′,’22′:’HD%20720p’,'37′:’HD%201080p’};try{args=yt.getConfig(’SWF_ARGS’);video_title=yt.getConfig(’VIDEO_TITLE’)}catch(e){}if(args){var fmt_url_map=unescape(args['fmt_url_map']);if(fmt_url_map==”)return;video_id=args['video_id'];video_hash=args['t'];video_title=video_title.replace(/[%22\'\?\\\/\:\*%3C%3E]/g,”);var fmt=new Array();var formats=fmt_url_map.split(’,');var format;for(var i=0;i%3Cformats.length;i++){var format_elems=formats[i].split(’|');fmt[format_elems[0]]=unescape(format_elems[1])}for(format in fmt_labels){if(fmt[format]!=null){download_code.push(’%3Ca%20href=\”+(fmt[format]+’&title=’+video_title)+’\'%3E’+fmt_labels[format]+’%3C/a%3E’)}elseif(format==’18′){download_code.push(’%3Ca%20href=\’http://www.youtube.com/get_video?fmt=18&video_id=’+video_id+’&t=’+video_hash+’\'%3E’+fmt_labels[format]+’%3C/a%3E’)}}}if(video_id==null||video_hash==null)return;var div_embed=document.getElementById(’watch-embed-div’);if(div_embed){var div_download=document.createElement(’div’);div_download.innerHTML=’%3Cbr%20/%3E%3Cspan%20id=\’download-youtube-video\’%3EDownload:%20′+download_code.join(’%20|%20′)+’%3C/span%3E’;div_embed.appendChild(div_download)}})() Similar Articles Productive Geek Tips Watch YouTube Videos in Cinema Style in FirefoxDownload YouTube Videos with Cheetah YouTube DownloaderStop YouTube Videos from Automatically Playing in FirefoxImprove YouTube Video Viewing in Google ChromeConvert YouTube Videos to MP3 with YouTube Downloader TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 PCmover Professional 15 Great Illustrations by Chow Hon Lam Easily Sync Files & Folders with Friends & Family Amazon Free Kindle for PC Download Stretch popurls.com with a Stylish Script (Firefox) OldTvShows.org – Find episodes of Hitchcock, Soaps, Game Shows and more Download Microsoft Office Help tab

• Review: A Quick Look at Reflector

  - by James Michael Hare

  I, like many, was disappointed when I heard that Reflector 7 was not free, and perhaps that’s why I waited so long to try it and just kept using my version 6 (which continues to be free).  But though I resisted for so long, I longed for the better features that were being developed, and began to wonder if I should upgrade.  Thus, I began to look into the features being offered in Reflector 7.5 to see what was new. Multiple Editions Reflector 7.5 comes in three flavors, each building on the features of the previous version: Standard – Contains just the Standalone application ($70) VS – Same as Standard but adds Reflector Object Browser for Visual Studio ($130) VSPro – Same as VS but adds ability to set breakpoints and step into decompiled code ($190) So let’s examine each of these features. The Standalone Application (Standard, VS, VSPro editions) Popping open Reflector 7.5 and looking at the GUI, we see much of the same familiar features, with a few new ones as well: Most notably, the disassembler window now has a tabbed window with navigation buttons.  This makes it much easier to back out of a deep-dive into many layers of decompiled code back to a previous point. Also, there is now an analyzer which can be used to determine dependencies for a given method, property, type, etc. For example, if we select System.Net.Sockets.TcpClient and hit the Analyze button, we’d see a window with the following nodes we could expand: This gives us the ability to see what a given type uses, what uses it, who exposes it, and who instantiates it. Now obviously, for low-level types (like DateTime) this list would be enormous, but this can give a lot of information on how a given type is connected to the larger code ecosystem. One of the other things I like about using Reflector 7.5 is that it does a much better job of displaying iterator blocks than Reflector 6 did. For example, if you were to take a look at the Enumerable.Cast() extension method in System.Linq, and dive into the CastIterator in Reflector 6, you’d see this: But now, in Reflector 7.5, we see the iterator logic much more clearly: This is a big improvement in the quality of their code disassembler and for me was one of the main reasons I decided to take the plunge and get version 7.5. The Reflector Object Browser (VS, VSPro editions) If you have the .NET Reflector VS or VSPro editions, you’ll find you have in Visual Studio a Reflector Object Browser window available where you can select and decompile any assembly right in Visual Studio. For example, if you want to take a peek at how System.Collections.Generic.List<T> works, you can either select List<T> in the Reflector Object Browser, or even simpler just select a usage of it in your code and CTRL + Click to dive in. – And it takes you right to a source window with the decompiled source: Setting Breakpoints and Stepping Into Decompiled Code (VSPro) If you have the VSPro edition, in addition to all the things said above, you also get the additional ability to set breakpoints in this decompiled code and step through it as if it were your own code: This can be a handy feature when you need to see why your code’s use of a BCL or other third-party library isn’t working as you expect. Summary Yes, Reflector is no longer free, and yes, that’s a bit of a bummer. But it always was and still is a very fine tool. If you still have Reflector 6, you aren’t forced to upgrade any longer, but getting the nicer disassembler (especially for iterator blocks) and the handy VS integration is worth at least considering upgrading for.  So I leave it up to you, these are some of the features of Reflector 7.5, what’s your thoughts?

• Experience the iPad UI On Your PC

  - by Matthew Guay

  Want to test drive iPad without heading over to an Apple store?  Here’s a way you can experience some of the iPad UI straight from your browser! The iPad is the latest gadget from Apple to wow the tech world, and people even waited in line all night to be one of the first to get their hands on one.  Thanks to a simple JavaScript trick, however, you can get a feel for some of its new features without leaving your computer.  This won’t let you try out everything on the iPad, but it will let you see how the new lists and pop-over menus work just like they do in the new apps. Test drive the iPad’s UI from your browser Normally, the Apple iPhone developer library online looks like a standard webpage. But, on the iPad, it looks and feels like a full-blown native iPad app.  With a nifty JavaScript trick from boredzo.org you can use this same interface on your PC.  Since the iPad uses the Safari browser, we ran this test in Safari for Windows.  If you don’t already have it installed, you can download it from Apple (link below) and setup as normal. Now, open Safari and browse to Apple’s developer page at: http://www.developer.apple.com   Now, enter the following in the address bar, and press Enter. javascript:localStorage.setItem('debugSawtooth', 'true')   Finally, click this link to go to the iPhone OS documentation. http://developer.apple.com/iphone/library/iPad/ After a short delay, it should open in full iPad style! The left menu works just like the menus on the iPad, complete with transitions.  It feels entirely like a native application, instead of a webpage.  To scroll through text, click and pull up or down similar to the way you would use it on a touch screen. Some pages even include a pop-over menu like many of the new iPad apps use. Note that the page will be rendered for the size of your browser, and if you resize your window the page will not resize with it.  Simply press F5 to reload the page, and it will resize to fit the new window size.  If you resize your window to be tall and narrow, like the iPad in horizontal mode, the webpage will change and the left menu will disappear in lieu of a drop-down menu just like it would if you rotated the iPad. This works in Chrome as well, since it, like Safari, is based on Webkit.  However, it didn’t seem to work in our test on Firefox or other browsers. We’ve previously covered how you can experience some of the iPhone’s UI with the online iPhone user guide.  Check it out if you haven’t yet: View Mobile Websites in Windows with Safari 4 Developer Tools Conclusion Although this doesn’t let you really try out all of the iPad’s interface, it at least gives you a taste of how it works.  It’s exciting to see how much functionality can be packed into webapps today.  And don’t forget, How-to Geek is giving away an iPad to a random fan!  Head over to our Facebook page and fan How-to Geek if you haven’t already done so.

• Combine the Address & Search Bars in Firefox

  - by Asian Angel

  The Search Bar in Firefox is very useful for finding additional information or images while browsing but the UI space it takes up can be frustrating at times. Now you can reclaim that UI space and still have access to all that searching goodness with the Foobar extension. Note: This is about the Foobar Firefox extension and not to be confused with Foobar2000 the open source music player. Before If you have the “Search Bar” displayed there is no doubt that it is taking up valuable space in your browser’s UI. What you need is the ability to reclaim that UI space and still have the same access to your search capability as before…no more sacrificing one for a gain with the other. After As soon as you have installed the extension you can see that the top part of your browser will look much sleeker without the “Search Bar” to clutter it up. The “Search Engine Icon” will now be visible inside of your “Address Bar” as seen here. You will be able to access the same “Search Engine Menu” as before by clicking on the “Search Engine Icon”. There are two display modes for search results (setting available in the “Options”). The first one shown here is “Simple Mode” where all results are in a condensed format. Notice that not only are there search suggestions but also “Bookmarks & History” listings as well. You can literally get the best of both when conducting a search. Note: The number of entries for search suggestions and bookmark/history listings can be adjusted higher or lower in the “Options”. The second one is “Rich Mode” where the results are shown with more details. Choose the “mode” that best suits your personal style. For our first example you can see the results when we conducted a quick search on “Windows 7” (using the first of the three offerings shown from Bing). Our second example was a search for “Flowers” using our Photobucket search engine. Once again nice results opened in a new tab for us. Options The options are easy to go through. It is really nice to be able to choose the number of results that you want displayed and the format that you want them shown in. Note: Changing the “Suggestion popup style” will require a browser restart to take effect. Conclusion If you love using the “Search Bar” in Firefox but want to reclaim the UI space then you will definitely want to add this extension to your browser. The ability to customize the number of results and choose the formatting make this extension even better.

• How to Add Your Gmail Account to Outlook 2013 Using IMAP

  - by Lori Kaufman

  If you use Outlook to check and manage your email, you can easily use it to check your Gmail account as well. You can setup your Gmail account to allow you to synchronize email across multiple machines using email clients instead of a browser. We will show you how to use IMAP in your Gmail account so you can synchronize your Gmail account across multiple machines, and then how to add your Gmail account to Outlook 2013. To setup your Gmail account to use IMAP, sign in to your Gmail account and go to Mail. Click the Settings button in the upper, right corner of the window and select Settings from the drop-down menu. On the Settings screen, click Forwarding and POP/IMAP. Scroll down to the IMAP Access section and select Enable IMAP. Click Save Changes at the bottom of the screen. Close your browser and open Outlook. To begin adding your Gmail account, click the File tab. On the Account Information screen, click Add Account. On the Add Account dialog box, you can choose the E-mail Account option which automatically sets up your Gmail account in Outlook. To do this enter your name, email address, and the password for your Gmail account twice. Click Next. The progress of the setup displays. The automatic process may or may not work. If the automatic process fails, select Manual setup or additional server types, instead of E-mail Account, and click Next. On the Choose Service screen, select POP or IMAP and click Next. On the POP and IMAP Account Settings enter the User, Server, and Logon Information. For the Server Information, select IMAP from the Account Type drop-down list and enter the following for the incoming and outgoing server information: Incoming mail server: imap.googlemail.com Outgoing mail server (SMTP): smtp.googlemail.com Make sure you enter your full email address for the User Name and select Remember password if you want Outlook to automatically log you in when checking email. Click More Settings. On the Internet E-mail Settings dialog box, click the Outgoing Server tab. Select the My outgoing server (SMTP) requires authentication and make sure the Use same settings as my incoming mail server option is selected. While still in the Internet E-mail Settings dialog box, click the Advanced tab. Enter the following information: Incoming server: 993 Incoming server encrypted connection: SSL Outgoing server encrypted connection TLS Outgoing server: 587 NOTE: You need to select the type of encrypted connection for the outgoing server before entering 587 for the Outgoing server (SMTP) port number. If you enter the port number first, the port number will revert back to port 25 when you change the type of encrypted connection. Click OK to accept your changes and close the Internet E-mail Settings dialog box. Click Next. Outlook tests the accounts settings by logging into the incoming mail server and sending a test email message. When the test is finished, click Close. You should see a screen saying “You’re all set!”. Click Finish. Your Gmail address displays in the account list on the left with any other email addresses you have added to Outlook. Click the Inbox to see what’s in your Inbox in your Gmail account. Because you’re using IMAP in your Gmail account and you used IMAP to add the account to Outlook, the messages and folders in Outlook reflect what’s in your Gmail account. Any changes you make to folders and any time you move email messages among folders in Outlook, the same changes are made in your Gmail account, as you will see when you log into your Gmail account in a browser. This works the other way as well. Any changes you make to the structure of your account (folders, etc.) in a browser will be reflected the next time you log into your Gmail account in Outlook.

• Session and Pop Up Window

  - by imran_ku07

   Introduction :        Session is the secure state management. It allows the user to store their information in one page and access in another page. Also it is so much powerful that store any type of object. Every user's session is identified by their cookie, which client presents to server. But unfortunately when you open a new pop up window, this cookie is not post to server with request, due to which server is unable to identify the session data for current user.         In this Article i will show you how to handle this situation,  Description :         During working in a application, i was getting an Exception saying that Session is null, when a pop window opens. After seeing the problem more closely i found that ASP.NET_SessionId cookie for parent page is not post in cookie header of child (popup) window.         Therefore for making session present in both parent and child (popup) window, you have to present same cookie. For cookie sharing i passed parent SessionID in query string,   window.open('http://abc.com/s.aspx?SASID=" & Session.SessionID &','V');           and in Application_PostMapRequestHandler application Event, check if the current request has no ASP.NET_SessionId cookie and SASID query string is not null then add this cookie to Request before Session is acquired, so that Session data remain same for both parent and popup window.    Private Sub Application_PostMapRequestHandler(ByVal sender As Object, ByVal e As EventArgs)           If (Request.Cookies("ASP.NET_SessionId") Is Nothing) AndAlso (Request.QueryString("SASID") IsNot Nothing) Then               Request.Cookies.Add(New HttpCookie("ASP.NET_SessionId", Request.QueryString("SASID")))           End If       End Sub           Now access Session in your parent and child window without any problem. How this works :          ASP.NET (both Web Form or MVC) uses a cookie (ASP.NET_SessionId) to identify the user who is requesting. Cookies are may be persistent (saved permanently in user cookies ) or non-persistent (saved temporary in browser memory). ASP.NET_SessionId cookie saved as non-persistent. This means that if the user closes the browser, the cookie is immediately removed. This is a sensible step that ensures security. That's why ASP.NET unable to identify that the request is coming from the same user. Therefore every browser instance get it's own ASP.NET_SessionId. To resolve this you need to present the same parent ASP.NET_SessionId cookie to the server when open a popup window.           You can confirm this situation by using some tools like Firebug, Fiddler,  Summary :          Hopefully you will enjoy after reading this article, by seeing that how to workaround the problem of sharing Session between different browser instances by sharing their Session identifier Cookie.

• IE9 and the Mystery of the Broken Video Tag

  - by David Wesst

  I was very excited when Microsoft released the Internet Explorer 9 Release Candidate. As far as I was concerned, this was another nail in the coffin for IE6 and step in the right direction for us .NET web developers as our base camp was finally starting to support the latest and greatest future-web standards. Unfortunately, my celebration was short lived as I soon hit a snag while loading up an HTML5 site I was building in Visual Studio 2010. The Mystery After updating Internet Explorer, I ran my HTML5 site that had the oh-so-lovely HTML5 video tag showing a video. Even though this worked in IE9 Beta, it appeared that IE9 RC could not load the same file. I figured that it was the video codec. Maybe IE9 RC no longer supported the video codec I used to encode my video. Here's the code I used: <video width="854" height="480" id="myOtherVideo" autoplay="" controls=""> <source src="/DemoSite1/Media/big_buck_bunny.mp4"/> <div> <p>Your browser does not support HTML5 Video.</p> </div> </video> As you can see from the code, I had the "fail-safe" code inside the video tag. The idea there being that if the video tag, or the video files themselves, are not supported by the browser my video should fail gracefully. What was even more strange was the fact that it worked in all the other HTML5 browsers that supported video. The Investigation Whoa! DJ stop the music. How can any of that make sense? Would the IE team really take such huge strides forward only to forget to include a feature that was already in the beta? I don't think so. I did plenty of searching on the web and asking around on the web, but could not seem to find anyone else having the same problem. Eventually I came across this post talking about declaring the MIME type in the .htaccess file. That got me thinking: does my web server support the video MIME type? I was using VS2010, so how do I know what kind of MIME types are supported by default? Still, my page hosted in Cassini (the web development server in VS2010) works on the other browsers. Why wouldn't it work with IE9 RC? To answer that, it was time to open up the upgraded toolbox known as the Developer's Tools in IE9 and use the new Network Tab. The Conclusion If you take a closer look at the results displayed from the Network tab, you can see that IE9 RC has interpreted the video file as text/html rather than video/mp4. To make this work, I decided to use IIS to debug my HTML5 web application by setting the web project's properties. Then, I added the MIME types that I want to support (i.e. video/mp4, video/ogg, video/webm). Et voila! The Mystery of the Broken Video Tag is solved. After Thoughts After solving the mystery, I still had the question about why my site worked in Chrome, Safari, and Firefox 3.6. After asking around, the best answer that I received was from my colleague Tyler Doerksen. He said that IE9 likely depends on the server telling it what kind of file it is downloading rather than trying to read the metadata about the data it is trying to download before doing anything. I have no facts to back this up, but it makes sense to me. In a browser war where milliseconds can make your browser fall back a few places in the race for supremacy, maybe the IE team opted to depend on the server knowing what kind of content it is serving up. Makes sense to me. In any case, that is just an educated guess. If you have any comments, feel free to post on them below. This post also appears at http://david.wes.st

• Using HTML5 Today part 3&ndash; Using Polyfills

  - by Steve Albers

  Shims helps when adding semantic tags to older IE browsers, but there is a huge range of other new HTML5 features that having varying support on browsers.  Polyfills are JavaScript code and/or browser plug-ins that can provide older or less featured browsers with API support.  The best polyfills will detect the whether the current browser has native support, and only adds the functionality if necessary.  The Douglas Crockford JSON2.js library is an example of this approach: if the browser already supports the JSON object, nothing changes.  If JSON is not available, the library adds a JSON property in the global object. This approach provides some big benefits: It lets you add great new HTML5 features to your web sites sooner. It lets the developer focus on writing to the up-and-coming standard rather than proprietary APIs. Where most one-off legacy code fixes tends to break down over time, well done polyfills will stop executing over time (as customer browsers natively support the feature) meaning polyfill code may not need to be tested against new browsers since they will execute the native methods instead. Your should also remember that Polyfills represent an entirely separate code path (and sometimes plug-in) that requires testing for support.  Also Polyfills tend to run on older browsers, which often have slower JavaScript performance.  As a result you might find that performance on older browsers is not comparable. When looking for Polyfills you can start by checking the Modernizr GitHub wiki or the HTML5 Please site. For an example of a polyfill consider a page that writes a few geometric shapes on a <canvas> <script src="jquery-1.7.1.min.js"><script> <script> $(document).ready(function () { drawCanvas(); }); function drawCanvas() { var context = $("canvas")[0].getContext('2d'); //background context.fillStyle = "#8B0000"; context.fillRect(5, 5, 300, 100); // emptybox context.strokeStyle = "#B0C4DE"; context.lineWidth = 4; context.strokeRect(20, 15, 80, 80); // circle context.arc(160, 55, 40, 0, Math.PI * 2, false); context.fillStyle = "#4B0082"; context.fill(); </script>   The result is a simple static canvas with a box & a circle:   …to enable this functionality on a pre-canvas browser we can find a polyfill.  A check on html5please.com references  FlashCanvas.  Pull down the zip and extract the files (flashcanvas.js, flash10canvas.swf, etc) to a directory on your site.  Then based on the documentation you need to add a single line to your original HTML file: <!--[if lt IE 9]><script src="flashcanvas.js"></script><![endif]—> …and you have canvas functionality!  The IE conditional comments ensure that the library is only loaded in browsers where it is useful, improving page load & processing time. Like all Polyfills, you should test to verify the functionality matches your expectations across browsers you need to support.  For instance the Flash Canvas home page advertises 70% support of HTML5 Canvas spec tests.

• How to share session cookies between Internet Explorer and an ActiveX components hosted in a webpage

  - by jerem

  I am currently working on a .Net application which makes HTTP requests to some web applications hosted on a IIS server. The application is deployed through ClickOnce and is working fine on simple networks architectures. One of our customers has a very complex network involving a custom authentication server on which the user has first to log himself in order to be authenticated and get access to other applications on this network. Once authenticated on this server, a session cookie is created and sent to the user. Every time the user then makes a request on a secured server of the network, this cookie is checked to grant access to the user. If this cookie is not sent with the request, the user is redirected to the login page. The only browser used is Internet Explorer. This cookie cannot be accessed from our .net application since it is executed in another process than the Internet Explorer process which was used to log the user in, and thus is not sent with our requests, which cannot be completed since the server redirects every of our requests to the login page. I had a look at embedding my application into Internet Explorer by making the main control COM visible and creating it on an HTML page with an tag. It is working properly, however the sessions cookies set earlier in the browser are not sent when the ActiveX control makes web requests. I was hoping this sharing of the session information would be automatic (although I didn't really believe it). So my questions are : Is it possible to have access to this cookie in the embedded ActiveX? How? Does it make a difference to use a .Net COM-interop component instead of a "true" ActiveX control? Also, are there specific security words to describe this kind of behaviors (given that I am not an expert at all on security topics, this lack of proper terminology makes it a lot harder to find the needed resources)? My goal is to have my application's requests look the same from the requests made by the host browser's requests, and I thought that embedding the application as an ActiveX control into the browser was the only way to achieve this, however any suggestion on another to do this is welcome.

• Errors with shotgun gem and msvcrt-ruby18.dll when running my Sinatra app

  - by Adam Siddhi

  Greetings, Every time I make a change to a Sinatra app I'm working on and try to refresh the browser (located at http://localhost:4567/) the browser will refresh and, the console window seems to restart the WEB brick server. The problem is that the content in the browser window does not change. A friend of mine told me it was a shotgun issue and referred me to rtomayko's shotgun gem: http://github.com/rtomayko/shotgun On this page I read that the shotgun gem would basically solve my problem, allowing the changes made to my app to show up in the browser window after I refresh it. So I installed the shotgun gem. The installation was successful. To activate the shotgun function you have to type shotgun before the file name. In this case my Sinatra app's file name is shortener.rb When I type shotgun shortener.rb to run my Sinatra app I get this error: C:\ruby\sinatrashotgun shortener.rb c:/Ruby19/lib/ruby/gems/1.9.1/gems/shotgun-0.6/bin/shotgun:137:in `': No such f ile or directory - uname (Errno::ENOENT) from c:/Ruby19/lib/ruby/gems/1.9.1/gems/shotgun-0.6/bin/shotgun:137:in block in ' from c:/Ruby19/lib/ruby/gems/1.9.1/gems/shotgun-0.6/bin/shotgun:136:in each' from c:/Ruby19/lib/ruby/gems/1.9.1/gems/shotgun-0.6/bin/shotgun:136:in find' from c:/Ruby19/lib/ruby/gems/1.9.1/gems/shotgun-0.6/bin/shotgun:136:in <top (required)>' from c:/Ruby19/bin/shotgun:19:inload' from c:/Ruby19/bin/shotgun:19:in `' I should also mention that before testing the shotgun method out to see if it worked, I installed the mongrel (I realize I should have checked to see if shotgun worked before doing this as installing mongrel has complicated this problem). So on top of getting the error message above I also get a pop up window from Ruby.exe saying: Ruby.exe - Unable to load component This application has failed to start because msvcrt-ruby18.dll was not found. Re-installing the application may fix this problem. I have no idea what msvcrt-ruby18.dll is but I know that installing either shotgun and/or mongrel created this problem. Where to go from here? Thanks, Adam

• Save a PDF created with FPDF php library in a MySQL blob field

  - by Davide Gualano

  I need to create a pdf file with the fpdf library and save it in a blob field in my MySQL database. The problem is, when I try to retrieve the file from the blob field and send it to the browser for the download, the donwloaded file is corrupted and does not display correctly. The same pdf file is correctly displayed if I send it immediately to the browser without storing it in the db, so it seems some of the data gets corrupted when is inserted in the db. My code is something like this: $pdf = new MyPDF(); //class that extends FPDF and create te pdf file $content = $pdf->Output("", "S"); //return the pdf file content as string $sql = "insert into mytable(myblobfield) values('".addslashes($content)."')"; mysql_query($sql); to store the pdf, and like this: $sql = "select myblobfield from mytable where id = '1'"; $result = mysql_query($sql); $rs = mysql_fetch_assoc($result); $content = stripslashes($rs['myblobfield']); header('Content-Type: application/pdf'); header("Content-Length: ".strlen(content)); header('Content-Disposition: attachment; filename=myfile.pdf'); print $content; to send it to the browser for downloading. What am I doing wrong? If I change my code to: $pdf = new MyPDF(); $pdf->Output(); //send the pdf to the browser the file is correctly displayed, so I assume that is correctly generated and the problem is in the storing in the db. Thanks in advance.

• Selenium RC throws sessionsid should not be null exception with assertTextPresent, phpunit 3.4 bug o

  - by user342775

  I am looking to migrate my selenium RC tests to using PHPUnit 3.4.12 from PHPUnit 3.3.2 The selenium test will fail with an exception of the following when I use assertTextPresent() PHPUnit_Framework_Exception: Response from Selenium RC server for getLocation(). ERROR Server Exception: sessionId should not be null; has this session been started yet?. For example: public function testSending($browser) { ... $browser->click("send"); $browser->waitForPageToLoad("30000"); $browser->assertTextPresent("text"); } Below is the selenium RC log (running on Windows): 15:40:19.676 INFO - Command request: isTextPresent[text, ] on session 153d03a123c42098711994f43c2db34 15:40:19.691 INFO - Got result: OK,false on session 153d023a123c42098711994f43cdb34 15:40:19.879 INFO - Command request: testComplete[, ] on session 153d023a123c4298711994f43c2db34 15:40:19.879 INFO - Killing Firefox... 15:40:20.269 INFO - Got result: OK on session 153d023a123c42098711994f43c2db34 15:40:20.472 INFO - Command request: getLocation[, ] on session null 15:40:20.472 ERROR - Exception running 'getLocation 'command on session null java.lang.NullPointerException: sessionId should not be null; has this session been started yet? As you can see, the test should have completed as indicated by the "Killing Firefox" bit, but it instead continued to do something else and triggered the getLocation[, ] command which caused the exception. I have tried the same test with PHPUnit 3.3.2 which did not produce this problem - the test would happily end without the getLocation(). Any ideas? thanks

• Retrieve parent node from selection (range) in Gecko and Webkit

  - by Jason

  I am trying to add an attribute when using a wysiwyg editor that uses "createLink" command. I thought it would be trivial to get back the node that is created after the browse executes that command. Turns out, I am only able to grab this newly created node in IE. Any ideas? The following code demonstrates the issue (debug logs at bottom show different output in each browser): var getSelectedHTML = function() { if ($.browser.msie) { return this.getRange().htmlText; } else { var elem = this.getRange().cloneContents(); return $("<p/>").append($(elem)).html(); } }; var getSelection = function() { if ($.browser.msie) { return this.editor.selection; } else { return this.iframe[0].contentDocument.defaultView.getSelection(); } }; var getRange = function() { var s = this.getSelection(); return (s.getRangeAt) ? s.getRangeAt(0) : s.createRange(); }; var getSelectedNode = function() { var range = this.getRange(); var parent = range.commonAncestorContainer ? range.commonAncestorContainer : range.parentElement ? range.parentElement(): range.item(0); return parent; }; // **** INSIDE SOME EVENT HANDLER **** if ($.browser.msie) { this.ec("createLink", true); } else { this.ec("createLink", false, prompt("Link URL:", "http://")); } var linkNode = $(this.getSelectedNode()); linkNode.attr("rel", "external"); $.log(linkNode.get(0).tagName); // Gecko: "body" // IE: "a" // Webkit: "undefined" $.log(this.getSelectedHTML()); // Gecko: "<a href="http://site.com">foo</a>" // IE: "<A href="http://site.com" rel=external>foo</A>" // Webkit: "foo" $.log(this.getSelection()); // Gecko: "foo" // IE: [object Selection] // Webkit: "foo" Thanks for any help on this, I've scoured related questions on SO with no success!

• Locking issues with replacing files on a website

  - by Moe Sisko

  I want to replace existing files on an IIS website with updated versions. Say these files are large pdf documents, which can be accessed via hyperlinks. The site is up 24x7, so I'm concerned about locking issues when a file is being updated at exactly the same time that someone is trying to read the file. The files are updated using C# code run on the server. I can think of two options for opening the file for writing. Option 1) Open the file for writing, using FileShare.Read : using (FileStream stream = new FileStream(path, FileMode.Create, FileAccess.Write, FileShare.Read)) While this file is open, and a user requests the same file for reading in a web browser via a hyperlink, the document opens up as a blank page. Option 2) Open the file for writing using FileShare.None : using (FileStream stream = new FileStream(path, FileMode.Create, FileAccess.Write, FileShare.None)) While this file is open, and a user requests the same file for reading in a web browser via a hyperlink, the browser shows an error. In IE 8, you get HTTP 500, "The website cannot display the page", and in Firefox 3.5, you get : "The process cannot access the file because it is being used by another process." The browser behaviour kind of makes sense, and seem reasonable. I guess its highly unlikely that a user will attempt to read a file at exactly the same time you are updating it. It would be nice if somehow, the file update was atomic, like updating a database with SQL wrapped around a transaction. I'm wondering if you guys worry about this sort of thing, and prefer either of the above options, or even have other options of your own for updating files.

• What is the proper way to URL encode Unicode characters?

  - by Josh Gibson

  I know of the non-standard %uxxxx scheme but that doesn't seem like a wise choice since the scheme has been rejected by the W3C. Some interesting examples: The heart character. If I type this into my browser: http://www.google.com/search?q=? Then copy and paste it, I see this URL http://www.google.com/search?q=%E2%99%A5 which makes it seem like Firefox (or Safari) is doing this. urllib.quote_plus(x.encode("latin-1")) '%E2%99%A5' which makes sense, except for things that can't be encoded in Latin-1, like the triple dot character. … If I type the URL http://www.google.com/search?q=… into my browser then copy and paste, I get http://www.google.com/search?q=%E2%80%A6 back. Which seems to be the result of doing urllib.quote_plus(x.encode("utf-8")) which makes sense since … can't be encoded with Latin-1. But then its not clear to me how the browser knows whether to decode with UTF-8 or Latin-1. Since this seems to be ambiguous: In [67]: u"…".encode('utf-8').decode('latin-1') Out[67]: u'\xc3\xa2\xc2\x80\xc2\xa6' works, so I don't know how the browser figures out whether to decode that with UTF-8 or Latin-1. What's the right thing to be doing with the special characters I need to deal with?

• How can I print a web page on a server?

  - by Gavin Schultz

  Suppose I develop a web page using the cool Google visualization API, and it does everything the user wants. They can the parameters, look at the graphs, and print the page to get a reasonable-looking report. All good. Now suppose I want to do the same thing server-side. For example, say we need a set of report generated at a specific time of day, printed to a PDF and emailed to a manager. It's not a user-initiated action, so we don't have a user's browser or their printer. We have a URL that would render the report if we had a browser, and that's it. Is there a good way to do this server-side? Is this just foolish? Has anyone done anything like that before? Do any of the major browsers have APIs that might provide such functionality? Keep in mind too that it's not just static HTML; probably javascript will be running first to shift the DOM around. I know we could implement a whole different reporting engine on the server side to do this, but that will (a) generate reports that look a bit different, and (b) require me to build/maintain two sets of functionality. Instead, I'd be happy if I could just render the page / pages I want in an invisible server-side browser and print it to a PDF (let's mostly ignore that step - I know any number of PDF printer drivers that could do this). I don't really want to do it ugly either - i.e. by starting a browser process and then sending keystrokes directly to the window either - that's just bound to fall apart with a slight nudge. The only related question I found had an answer like that. Any advice appreciated!

• Visual Studio 2010: very slow web applications debugging!

  - by micha12

  I recently installed Visual Studio 2010 (Ultimate edition, final version released in April), and found that debugging a web application became very slow (2-3 times slower than in Visual Studio 2008)! I took the same web application and checked the speed of loading of one of its pages in VS 2008 and VS 2010, and compared the time it takes to load the page. I tested it using 2 approaches: 1) debugging under ASP.NET Development Server (by pressing the "Start" button) and 2) using ASP.NET Development Server without debugging (by using the "View in Browser" menu command). And I got the following results for Visual Studio 2008 and 2010. 1) ASP.NET Development Server withoud debugging ("View in Browser"): the speed of page loading is the same in VS 2008 and 2010. 2) Debugging under ASP.NET Development Server ("Start" button): in VS 2010 the page takes more time to load than in VS 2008 - VS 2010 debugging is 2-3 times slower than in VS 2008! 3) At the same time, when debugging a web application in VS 2008, it takes the same time to load the page compared to when using only the "View in Browser" command. That is, VS 2008 debugging does not introduce any overhead to page loading in the web browser! I wanted to make sure that other people have the same problem with slow debugging of web applications in VS 2010. Can this issue be solved by any means? BTW, I am using Windows XP SP3. Thank you.

• With the advent of HTML 5, is there a point in using COMET anymore?

  - by h2g2java

  I am very tempted to use long wait http or periodic polling by the client to set up pseudo-sockets on the browser side, for an application that would be used publicly. But then on the 2nd thought, I am thinking HTML 5 is here. But on the 3rd thought, what is the percentage of browsers out there that remain non-HTML5 within 12 months, 24 months, 36 months? If there are at least 20% of browsers still incapable of HTML5, then I cannot depend on HTML5 because 20% of users not being able to access an application is a significant amount. What do you think, how would your advice be (to me and to developers in general)? Q1. Is there any point in rigging in COMET into an application anymore? I am thinking of gwt comet - http://code.google.com/p/gwt-comet/. Q2. Should we release a new public application within the next 2 months that is dependent on HTML5 sockets and tell non-HTML5 browser users "sorry, your browser version cannot access this application"? Or should we architect the apps to use communication like GWT RPC? Q3. I am also very distrustful of long wait http request. I have never used it before but I have a horrible feeling about it. I have been using 10 to 20 second client-side polling. Is long wait http request risky (risk of hanging a browser session)? Does long wait request present any additional security risk?

• Why wouldn't the default Control Adapter mappings work on Chrome or Safari?

  - by Deane

  I have confirmed that my Control Adapters are not triggering in Chrome and Safari. I've debugged, and the breakpoints inside the adapters just don't get hit in Chrome/Safari, when they work perfectly find in Firefox/IE. So, for Chrome/Safari, IIS is just ignoring the mapping. My AdapterMappings.browser file looks like this: <browsers> <browser refID="Default"> <controlAdapters> [...adapters here....] </controlAdapters> </browser> </browsers> This should provide mappings for all browsers, correct? I used the Charles proxy to check what user agents were being sent. They are: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1064 Safari/532.5 Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/531.22.7 (KHTML, like Gecko) Version/4.0.5 Safari/531.22.7 Any idea why this would be? Everything I've read tells me that my browser mappings are correct? And, as I said this works for IE/Firefox, so I know my configuration is technically correct.

• Fulfilling strange requirements with CSS (kind of simulating frames)

  - by Bernhard V

  Hi! I'm struggling to find a way to code a site according to our strange requirements. The site should be displayed correctly in all browsers from IE6 to Opera. The website is structured in three parts. It contains a header at the top, a navigation on the left an the rest of the screen should be filled with the content section. The following picture should help you better understand my description. Here comes the kicker: Each of the three sections should be scrollable separately and no browser scrollbar should appear. The page should be displayed similar as if it would use frames. Of course, on a big enough screen, no scroll bars should appear. It doesn't matter which way is used to display the site, although frames aren't an option an divs would be preferred. There are two conditions: The site should always fill the whole browser screen. The header and the content section should reach to the right border of the page, and the navigation as well as the content to the bottom. As soon as the site is scaled down -- whether due to resizing the browser window or due to a smaller resolution -- a scrollbar for every single section should appear, but no "browser scrollbar" for the whole page. The header should always retain it's height and the navigation always it's width. Do you know a way how all this can be achieved? Yours Bernhard

• Internet zone is opened when broswer is opened from installer created by .Net 3.5sp1

  - by priya

  Hi All, I have project created in VS2005 and .Net 2.0. The installation is a web-based installation. After installing the proe-requisites the installer opens up the browser to continue with web-based install. On this, it opens up in intranet zone and works perfectly. I recently migrated the project to VS2008 Sp1 and .Net 3.5sp1. No change in my code and the test environment. Here the browser gets opened up in the Internet zone which prevents it from moving forward, until unless I open up a new browser manually and copy paste the url. The internet security options on the both the case are - Internet --- High. For the case2, if i have the security internet option to be 'Medium', it works well. I am not sure why this issue comes up when I change the VS and .Net version. More over the browser gets opened with system priveleges rather than administrator privileges. Please let me know any solution on this. Thanks, Priya.R

• POST XML to server, receive PDF

  - by Shaggy Frog

  Similar to this question, we are developing a Web app where the client clicks a button to receive a PDF from the server. Right now we're using the .ajax() method with jQuery to POST the data the backend needs to generate the PDF (we're sending XML) when the button is pressed, and then the backend is generating the PDF entirely in-memory and sending it back as application/pdf in the HTTP response. One answer to that question requires the server-side save the PDF to disk so it can give back a URL for the client to GET. But I don't want the backend caching content at all. The other answer suggests the use of a jQuery plugin, but when you look at its code, it's actually generating a form element and then submitting the form. That method will not work for us since we are sending XML data in the body of the HTTP request. Is there a way to have the browser open up the PDF without caching the PDF server-side, and without requiring us to throw out our send-data-to-the-server-using-XML solution? (I'd like the browser to behave like it does when a form element is submitted -- a POST is made and then the browser looks at the Content-type header to determine what to do next, like load the PDF in the browser window, a la Safari)
