• Can't type into some text fields in any browser on Windows 7

  - by Zoltán

  I can't type into e.g. facebook's log in form with my computer. I hit my keys, but nothing happens. Special characters like c, c, š, etc. work. Backspace doesn't, delete does. This goes for Internet Explorer, Firefox and Chrome. This also happens with some other sites, sometimes even with gmail (or any google's log in form). I read somewhere that the solution is to reregister some dlls: regsvr32 mshtmled.dll regsvr32 jscript.dll regsvr32 /i mshtml.dll The first two work, the third one says The module "mshtml.dll" was loaded but the entry-point DllRegisterServer.dll was not found. And of course, running just the first two didn't help. Does anyone know how to fix this problem?

• Important Tips to make a user friendly Homepage

  - by Aditi

  We have done a lot of redesign work lately for many online businesses.. There are some basic things we want to stress into any web design which make it usable! Unfortunately most designers care about the graphic elements, clean code & navigation only. Most designers do not realize that a design they did could be a masterpiece to them but for a layman it could be tough to use. It is so very important to understand usability & call to action for any business and then implemented on their website Homepage. Showcase Offering The sole purpose of their websites needs to be mentioned on the homepage, what they are offering, why should one do business with them and why they are better than other competitors. Include a tag line under your logo that explicitly summarizes what the site or company does. Ease of Navigation Make it easier for your user to find what they are looking for, some archives, articles, services etc. A visible and easy to use Navigation allows just that. You may also want to feature some of the most visited content on the homepage itself. Search Form Let your users take advantage of a search form from your homepage, keep it visible enough so if they have trouble locating certain content using your navigation. The Search Bar will come handy in such situation. Especially if you have thousands and thousands of web pages. Liquid Layout There was a time when people used standard resolution, not any more. People have different screen sizes and most people now browse on handhelds. Try keeping liquid width so people can adjust as per their choice. First impression is last impression, leaving one through your perfect homepage can do wonders for your business.

• ASP.NET 4.0- CompressionEnabled Property in session state 4.0

  - by Jalpesh P. Vadgama

  Hello Guys, This blog has been quite for few days. Because i was busy with some personal and professional work both and that’s why i am not able to work on writing blog posts which i have discovered in last few days. Here is one features of asp.net 4.0 that I am going to explain. As a web developer we all know about session. Without the use of session any database driven web application is incomplete. As we all know unlike windows form web forms are state less so when user interacts with web application we need to maintain state amongst web pages and we are using session for maintaining state between web pages for each users. ASP.NET is also provide same kind of session state functionalities. ASP.Net Session state identify request coming for same user and same browser for specific session time out interval and its preserves values in session for that specific time intervals and that’s help us in maintaining state amongst web pages for a specific user. ASP.NET Session state allows us to store session in three way 1. IncProc 2. Session State Service 3. SQL Server. In SQL Server mode it will store session in SQL Server tables instead of storing it in Server Memory. ASP.NET 4.0 provides a new property called Compression Enabled that means when we store values in serialized form in SQL Server with GZip Compression and that results in better performance. For that you need to store property in web.config like following. <sessionState allowCustomSqlDatabase="true" sqlConnectionString="data source=Server;Initial Catalog=aspnetsessionstatedb" compressionEnabled="true" /> That’s it now with the use of this property you can have better performance when you are storing large amount of data in session.But still you need to decide that why you want to stored large amount of data in session because its against best practices.

• How can I get Opera speed-dial and password management features in other browsers?

  - by Howard Guo

  I heavily rely on Opera's speed dial and password management features. Lack of these two features is really stopping me from switching to another web browser such as Chrome or Firefox. Opera's password management has two unique characteristics which I rely on heavily: It saves passwords on all pages, (apparently) despite the page's meta data asking not to save passwords. It offers keyboard shortcut and button to automatically fill in username/passwords and all other fields in a login form, then automatically submit the form. (So I'm only one key/click away from logging into a website) How can I get those functions in other browsers? Thank you! Edit: Reason being that I use other web browsers at work and I wish they could have those functions.

• Douglas Adams Describes the Invention of the Ebook [Video]

  - by Jason Fitzpatrick

  In 1993, Douglas Adams–of The Hitch Hikers Guide to the Galaxy fame–lent his creative talent and voice to explaining the invention of the Ebook. The audio segment was produced almost 20 years ago by Adams to both promote his own work in digital format and the work of early ebook publisher Voyager Expanded Books. You may notice Adams refers to their product as a PowerBook, a name they kept until they heard Apple would be releasing a laptop with the same name (from then on the product was simply referred to as Expanded Books). The thoroughly modern video accompanying Adams concise and entertaining description of book history is an animation courtesy of U.K. designer Gavin Edwards, which he submitted to a contest hosted by The Literary Platform intended to match a clever animation with Adam’s monologue.

• =~ (equal-sign tilde) and m" ... " in .htaccess directive [closed]

  - by Lèse majesté

  I saw this bit of code on an old forum post: SSLRequire %{HTTP_HOST} =~ m"\.secure\.powweb\.com" And I was just wondering what the =~ and m" ... " meant. I've been searching online and in the Apache documentation for any mention of the equal-sign tilde operator, but I've found no mention of it. I know that some directives can take a tilde to use a regular expression, but I've never seen the m" ... " form used before. What exactly is that m" ... " for? Where else would you see this form?

• La rubrique Conception devient « ALM » sur Developpez.com, et couvre désormais toutes les phases du cycle de vie des applications

  Bonjour, L'équipe de rédaction a l'honneur de vous annoncer une importante amélioration au sommet des rubriques de Developpez.com. Pour lui donner plus d'importance et un plus grand impact, la méga-rubrique Conception devient « ALM » (Application lifecycle management). Ce sigle ne vous dit rien ?

• Visual Studio 2010 Type or namespace &lsquo;xyz&rsquo; does not exist in&hellip;

  - by Mike Huguet

  It pains me to write this post as I feel like an idiot for having wasted my time on this “problem.”  Hopefully in posting this, I can keep some other poor lost soul working at 4 AM in the morning from spending wasteful minutes scratching his head and getting frustrated.  The Visual Studio designer will work fine in resolving namespaces, but when you build you will get the “Type or namespace ‘xyz’ does not exist error.  If you see this error please take a look at your Errors List window and ensure that you have the “Warnings” option enabled.  It is very likely that you will see that there is a missing dependent reference.  Technorati Tags: Visual Studio

• MS Access: Why can I no longer right-click to add a hyperlink?

  - by gef05

  I've been working in an MS Access system for a while now. It's a form system where users enter data, add links, contacts etc. Pretty simple. On the form is a hyperlink field. For months I could right-click the field, and from the popup context menu select Hyperlink Add a hyperlink (something like that). This would allow me to browse to a network location, select a folder, click okay, and have the path automatically added to the field. Then it stopped working. It works fine for everyrone else but not me. What's stranger, if I go to another machine and login, I get the functionality back. Any ideas?

• Are Language Comparisons Meaningful?

  - by Prasoon Saurav

  Dr Bjarne Stroustrup in his book D&E says Several reviewers asked me to compare C++ to other languages. This I have decided against doing. Thereby, I have reaffirmed a long-standing and strongly held view: "Language comparisons are rarely meaningful and even less often fair" . A good comparison of major programming languages requires more effort than most people are willing to spend, experience in a wide range of application areas, a rigid maintenance of a detached and impartial point of view, and a sense of fairness. I do not have the time, and as the designer of C++, my impartiality would never be fully credible. -- The Design and Evolution of C++(Bjarne Stroustrup) Do you people agree with his this statement "Language comparisons are rarely meaningful and even less often fair"? Personally I think that comparing a language X with Y makes sense because it gives many more reasons to love/despise X/Y :-P What do you people think?

• Setting the Default Wiki Page in a SharePoint Wiki Library

  - by Damon Armstrong

  I’ve seen a number of blog posts about setting the default homepage in a wiki library, and most of them offer ways of accomplishing this task through PowerShell or through SharePoint designer.  Although I have become an ever increasing fan of PowerShell, I still prefer to stay away from it unless I’m trying to do something fairly complicated or I need a script that I can run over and over again.  If all you need to do is set the default homepage in a wiki library, there is an easier way! First, navigate to the wiki page you want to use as the default homepage.  Then click the Page tab in the ribbon.  In the Page Actions group there is a button called Make Homepage.  Click it.  A confirmation displays informing you that you are about to change the homepage.  Click OK and you will have a new homepage for your wiki library.  No PowerShell required.

• Block elements vs inline elements in HTML: why the distinction?

  - by EpsilonVector

  The distinction between block and inline elements always seemed strange to me. The whole difference is that a block element takes up the entire width thus forcing a line break before and after the element, and an inline element only takes up as much as the content. Why not just have one type of element- an inline element where you can also apply custom height/width, and use that? You want line breaks? Insert a <br />, or maybe add a special tag in the CSS for that behavior. The way it's now, I don't see it solving any problem, and instead it only forces a property that in my opinion should be decided by a designer. So why the two types?

• Where do you search/look for game developers for an indie game startup?

  - by G.Campos

  Hey there I just recently saw stackoverflow had a game dev sister site so here I am, wondering if you experienced fellows know where one can search/look for game developers for an indie game startup? In other words: I have a game idea which I've written down with as much detail as possible (so anyone else can understand how it works) and now I'm looking for a heavy php programmer with whom to pair up in order to go from idea to reality. I'm a front-end/interface designer and an intermediate programmer. I recognize my project requires heavy programming skills which I do not have as of today =) So, what websites, communities or places do you recommend I go look into? Where do good programmers interested in indie games go look for projects if they don't have their own? Thanks in advance G.Campos

• Tips or techniques to use when you do't know how to code something?

  - by janoChen

  I have a background as UI designer. And I realized that it is a bit hard for me to write a pieces of logic. Sometimes I get it right, but most of the time, I end up with something hacky (and it usually takes a lot of time). And is not that I don't like programming, in fact, I'm starting to like it as much as design. It's just that sometimes I think that I'm better at dealing with colors an shapes, rather than numbers and logic (but I want to change that). What I usually do is to search the solution on the Internet, copy the example, and insert it into my app (I know this is not a very good practice). I've heard that one tip was to write the logic in common English as comment before writing the actual code. What other tips and techniques I can use?

• Fetching templates via API. Who provides this service?

  - by Guandalino

  I'm mainly a server side developer. I'm not a designer, even if I understand web layouts, grids, CSS, typography, valid markup, etc. and I'm able to do some graphic work too (almost). It just takes a lot of time and the result is not always beautiful. I know there are tons of website templates sites out there, and I'd like to use their designs as a starting point for my customers' works, giving them the possibility to choose the design they like more. I'd just prefer to show the templates catalog to customers from within my site, fetching templates info (screenshots, description, etc) from a remote server using an API. TemplateMonster.com provides, or provided, such API. But the service responds with "Unauthorized usage". Are there other sites offering this kind of retrieval service?

• Determine whether a link points to a file on local host or foreign domain [migrated]

  - by user107157

  This has been a burning question for me ever since and I think it's interesting enough to discuss it on the forums. As most will know, in websites we include anchor links, stylesheets, script files (javascript) and images. For anchor links we use the form <a href="..." /> For stylesheets we may use the form <link rel="stylesheet" type="text/css" href="..." /> For javascript we may use <script src="..." /> For images we use <img src="..." /> So, the question is this: How do we know that what is in the link pointer (i.e. replacing the ... in each example) is a local file or a foreign entity? To make it clear, lets say I create a local file named "ashish.com". Now, my purpose is to create a link so that anybody who clicks on it may download it. So, my code would be thus: <a href="ashish.com">Download It</a> But this makes it ambiguous. I could also be referring to a website named "ashish.com" So, how does the computer magically know which one I mean? Or does it even know this? What would happen in such a scenario?

• Per-vertex animation with VBOs: VBO per character or VBO per animation?

  - by charstar

  Goal To leverage the richness of well vetted animation tools such as Blender to do the heavy lifting for a small but rich set of animations. I am aware of additive pose blending like that from Naughty Dog and similar techniques but I would prefer to expend a little RAM/VRAM to avoid implementing a thesis-ready pose solver. I would also like to avoid implementing a key-frame + interpolation curve solver (reinventing Blender vertex groups and IPOs), if possible. Scenario Meshes are animated using either skeletons (skinned animation) or some form of morph targets (i.e. per-vertex key frames). However, in either case, the animations are known in full at load-time, that is, there is no physics, IK solving, or any other form of in-game pose solving. The number of character actions (animations) will be limited but rich (hand-animated). There may be multiple characters using a each mesh and its animations simultaneously in-game (they will likely be at different frames of the same animation at the same time). Assume color and texture coordinate buffers are static. Current Considerations Much like a non-shader-powered pose solver, create a VBO for each character and copy vertex and normal data to each VBO on each frame (VBO in STREAMING). Create one VBO for each animation where each frame (interleaved vertex and normal data) is concatenated onto the VBO. Then each character simply has a buffer pointer offset based on its current animation frame (e.g. pointer offset = (numVertices+numNormals)*frameNumber). (VBO in STATIC) Known Trade-Offs In 1 above: Each VBO would be small but there would be many VBOs and therefore lots of buffer binding and vertex copying each frame. Both client and pipeline intensive. In 2 above: There would be few VBOs therefore insignificant buffer binding and no vertex data getting jammed down the pipe each frame, but each VBO would be quite large. Are there any pitfalls to number 2 (aside from finite memory)? I've found a lot of information on what you can do, but no real best practices. Are there other considerations or methods that I am missing?

• Should I avoid SharePoint Development in Visual Studio?

  - by SaphuA

  Not long ago I started an internship at a company that supplies SharePoint consultancy, hosting and development. While their consultancy seems to be pretty good and solid, I feel their development department lacks direction. The reason for this, most likely, is that they stopped outsourcing not too long ago. One thing that I've frequently bumped my head into is the following: My supervisor strongly insists that everything that can be done natively in SharePoint (somehow this includes editing xslt files in Designer) should be done in SharePoint. Even if this results in longer development time (at least when they make me write XSLT) and reduced usability. Her main arguments for this are: Better maintainability Editing the functionality doesn't require programming knowledge I feel the company is a little biassed and I am unable to get a decent discussion going. This is why I am looking for other places to get some responses on the subject (and not only on the arguments of my supervisor, but more on the subject in general). Kind regards

• Dude, where is my list instance?

  - by MOSSLover

  I saw an MSDN Forum post today, so I looked for a ListInstance Hidden property in SharePoint 2007 features.  There is none, but interestingly enough there is one in 2010.  I wondered what would happen if you did this: <Elements xmlns="http://schemas.microsoft.com/sharepoint/">   <ListInstance            FeatureId="00bfea71-de22-43b2-a848-c05709900100"            Title="Hidden List Test"            Description="Testing a hidden list."            TemplateType="100"            Hidden="TRUE"            OnQuickLaunch="FALSE"            Url="Lists/TestHidden" /> </Elements> It hides the entire list from SharePoint Designer and the browser, however you can hit the list by typing in the url in internet explorer.  Pretty cool stuff.  Enjoy guys.

• how do I write a functional specification quickly and efficiently

  - by giddy

  So I just read some fabulous articles by Joel on specs here. (Was written in 2000!!) I read all 4 parts, but Im looking for some methodical approaches to writing my specs. Im the only lonely dev, working on this fairly complicated app (or family of apps) for a very well known finance company. I've never made something this serious, I started out writing something like a bad spec, an overview of some sorts, and it has wasted a LOT of my time. Ive also made 3 mockup-kinda-thingies for my client so I have a good understanding of what they want. Also released a preview (a throw away working app with the most basic workflow), and Ive only written and tested some of the very core/base systems. I think the mistake Ive been making so far is not writing a detailed spec, so Im getting to it now. So the whole thing comprises of An MVC website (for admins & data viewing) 2 Silverlight modules (For 2 specific tasks) 1 Desktop Application Im totally short on time, resources and need to get this done quick, also, need to make sure these guys read it up equally quick and painlessly. So how do I go about it, Im looking for any tips, any real world stuff, how do you guys usually do it? Do you make a mock screenie of every dialog/form/page? Im thinking of making a dummy asp.net web forms project, then filling in html files in folders and making it look like my mvc url structure. Then having a section in the spec for the website and write up a page for every URL Ive got with a screenie. For my win forms app, Ive made somewhat of a demo Win Form project, would I then put in a dialog or stucture everything as I would in the real app and then screen shot it?

• Javascript autotab function not working on iPad or iPhone [migrated]

  - by freddy6

  I have this this piece of html code: <form name="postcode" method="post" onsubmit="return OnSubmitForm();"> <input class="postcode" maxlength="1" size="1" name="c" onKeyup="autotab(this, document.postcode.o)" /> <input class="postcode" maxlength="1" size="1" name="o" onKeyup="autotab(this, document.postcode.d)" /> <input class="postcode" maxlength="1" size="1" name="d" onKeyup="autotab(this, document.postcode.e)" /> <input class="postcode" maxlength="1" size="1" name="e" /> <br /> </form> which uses this javascript: <script> /* Auto tabbing script- By JavaScriptKit.com http://www.javascriptkit.com This credit MUST stay intact for use */ function autotab(original,destination){ if (original.getAttribute&&original.value.length==original.getAttribute("maxlength")) destination.focus() } </script><script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" type="text/javascript"></script> <script src="js/scripts.js" type="text/javascript"></script> <script type="text/javascript"> function OnSubmitForm() { if(document.postcode.operation[0].checked == true) { document.postcode.action ="plans.php"; } else if(document.postcode.operation[1].checked == true) { document.postcode.action ="plans_gas.php"; } else if(document.postcode.operation[2].checked == true) { document.postcode.action ="plans_duel.php"; } return true; } </script> As soon a you enter in one character into one of the text boxes it automatically tabs across the the next text box. This works fine on a pc or mac and on safari and also in all other browsers. But when viewing the webpage on an iPad or iPhone (using safari) the auto tabbing function does not work. Any ideas on how to make the auto tab work on these mobile devices?
