  • C# How do I replace an actual asterisk character (*) in a Regex expression?

    - by fraXis
    Hello, I have a statement: I have a string such as content = "* test *" I want to search and replace it with so when I am done the string contains this: content = "(*) test (*)" My code is: content = Regex.Replace(content, "*", "(*)"); But this causes an error in C# because it thinks that the * is part of the Regular Expressions Syntax. How can I modify this code so it changes all asterisks in my string to (*) instead without causing a runtime error? Thanks.

  • Is it possible to create a DateFormatter which converts a two-digit year into a four-digit year?

    - by DR
    In my Java application I use a DateFormat instance to parse date inputs. DateFormat fmt; fmt = DateFormat.getDateInstance(DateFormat.DEFAULT) // dd.MM.yyyy for de_DE The problem is that the user insists to enter dates in the form 31.12.11. Unfortunately this is parsed to 31.12.11. (0011-12-31 in ISO format) Instead I want the parsed date to become 31.12.2011 (2011-12-31 in ISO format). Can I modify the date format to somehow parse inputs that way?

  • How to distort the desktop screen

    - by HaifengWang
    Hi friends, I want to change the shape of the desktop screen, so what are displayed on the desktop will be distorted at the same time. And the user can still operate the PC with the mouse on the distorted desktop(Run the applications, Open the "My Computer" and so on). I think I must get the projection matrix of the screen coordinate at first. Then transform the matrix, and map the desktop buffer image to the distorted mesh. Are there any interfaces which can modify the shape of the desktop screen in OpenGL or DirectX? Would you please give me some tip on it. Thank you very much in advance. Please refer to the picture from http://oi53.tinypic.com/bhewdx.jpg BR, Haifeng Addition1: I'm sorry! Maybe I didn't express clearly what I want to implement. What I want to implement is to modify the shape of the screen. So we can distort the shapes of all the applications which are run on Windows at the same time. For example that the window of "My Computer" will be distorted with the distortion of the desktop screen. And we can still operate the PC with mouse from the distorted desktop(Click the shortcut to run a program). Addition2: The projection matrix is just my assume. There isn't any desktop projection matrix by which the desktop surface is projected to the screen. What I want to implement is to change the shape of the desktop, as the same with mapping the desktop to an 3D mesh. But the user can still operate the OS on the distorted desktop(Click the shortcut to run a program, open the ie to surf the internet). Addition3: The shapes of all the programs run on the OS are changed with the distortion of the screen. It's realtime. The user can still operate the OS on the distorted screen as usually. Maybe we can intercept or override the GPU itself to implement the effect. I'm investigating GDI, I think I can find some clue for that. The first step is to find how to show the desktop on the screen.

  • How to dynamically change the content of a facet in a custom component?

    - by romaintaz
    Hello, Let's consider that I want to extend an existing JSF component, such as the <rich:datatable/>. My main requirement is to dynamically modify the content of a <f:facet>, to change its content. What is the best way to achieve that? Or where is the best place in the code to achieve that? In my faces-config.xml, I have the following declaration: <faces-config> ... <component> <component-type>my.component.dataTable</component-type> <component-class>my.project.component.table.MyHtmlDataTable</component-class> </component> ... <render-kit> <render-kit-id>HTML_BASIC</render-kit-id> <renderer> <component-family>org.richfaces.DataTable</component-family> <renderer-type>my.renderkit.dataTable</renderer-type> <renderer-class>my.project.component.table.MyDataTableRenderer</renderer-class> </renderer> ... Also, my my-project.taglib.xml file (as I use Facelets) looks like: <facelet-taglib> <namespace>http://my.project/jsf</namespace> <tag> <tag-name>dataTable</tag-name> <component> <component-type>my.component.dataTable</component-type> <renderer-type>my.renderkit.dataTable</renderer-type> </component> </tag> So as you can see, I have two classes in my project for my custom datatable: MyHtmlDataTable and MyDataTableRenderer. One of my idea is to modify the content of the <f:facet> directly in the doEncodeBegin() method of my renderer. This is working (in fact almost working), but I don't really think that's the better place to achieve my modification. What do you think? Technical information: JSF 1.2, Facelets, Richfaces 3.3.2, Java 1.6

  • Getting a Soft Keyboard for a EditTextPreference

    - by user313135
    Hello, I have a shared preference that is being accesed via an EditTextPreference. I am in the process of porting this application to a device that does not have a hardware keyboard for text entry. When the time comes to modify the EditTextPreference, there is no soft keyboard that becomes available, and I am at a loss as to how to invoke the soft keyboard for text input to edit this preference. Thanks

  • Are there any StatusNet toolkits for .NET?

    - by Broam
    There are plenty of projects out there that assist developers in posting things to Twitter; the one I can think of off the top of my head is Twitterizer. Are there any projects for posting to StatusNet? Given that StatusNet implements an API very similar to Twitter, I could probably modify/extend Twitterizer to do just that. However, I'd like to avoid reinventing the wheel if at all possible if something exists already.

  • Add methods to generated WCF client proxy code

    - by dcstraw
    I'd like to add one additional method for each service operation in my WCF client proxy code (i.e. the generated class that derives from ClientBase). I have written a Visual Studio extension that has an IOperationContractGenerationExtension implementation, but this interface only seems to expose the ability to modify the service interface, not the ClientBase-derived class. Is there any way to generate new methods in the proxy client class?

  • does copyWithZone on an NSArray call copyWithZone on its elements too?

    - by malik
    Hi, here's the scenario, I have this array of Person objects. copyWithZone is implemented on Person and works as expected. I have an array of Person objects, however when I create a copy of the array and modify things in original array (change attributes of a Person) it chances the copy as well. So my best guess is that when I call copyWithZone on NSArray, it does not call it on its elements. Please confirm.

  • Can I customize the Magento app/code/core folder without affecting future upgrades?

    - by mck89
    I found a guide on how to add new attributes to users, it explains that for this operation I must modify some files in the app / code / core / Mage directory (the directory that contains Magento’s modules). But if i make some changes in that folder will this affect future upgrades? Will an upgrade will delete my changes? Should I limit the changes only to my modules to not have problems with updates?

  • How do I integrate a BSDF into a ray caster.

    - by pelb
    I'm trying to implement sub surface scattering at isosurfaces and looked up how a BSDF works mathematically. Implementing the reflective and diffuse part seems to be quite easy as i just have to evaluate phong at the isosurface intersection, but how do you I apply the transmissive part of the BSDF? In what way do i have to modify the ray direction. Any pointers to a practical implementation are welcome. Thanks and So long!

  • sfDoctrineGuard - how to ALWAYS join sfGuardProfile to sfGuardUser

    - by prodigitalson
    I want to make it so that anytime the db is queried for an sfGuardUserProfile it is autmoatically joined and hydrated with its related sfGuardUser. If i was using propel i would normally override the doSelectStmt method of the sfGuardUserProfilePeer class to inspect the Criteria and modify it as necessary as well as modifying the hydrate method of the sfGuardUserProfile class. Im not sure how to go about doing this in Doctrine though.

  • Problem with JQuery swapImage();

    - by VUELA
    Hello!~ On my articles page (http://www.adrtimes.squarespace.com/articles) I have each entry start with an image that changes on rollover. This is working fine. However, on my homepage (http://www.adrtimes.squarespace.com), I am loading in the 2 most recent articles that are not categorized as video, and the 2 most recent articles that are tagged as video. I am using jQuery load() to pull in the content from the articles page. Everything works ok with that except the swapImage rollovers on the homepage. i tried including the swapImage function as callbacks but only one group or the other will rollover properly, not both groups of content. I'm not sure what the problem is!! Here is the code: <script type="text/javascript"> <!-- $(function(){ $.swapImage(".swapImage"); /* Homepage */ // load recent articles $("#LoadRecentArticles").load("/articles/ .list-journal-entry-wrapper .journal-entry-wrapper:not(.category-video)", function(){ //callback... $("#LoadRecentArticles .journal-entry-wrapper").wrapAll('<div class="list-journal-entry-wrapper" />'); $("#LoadRecentArticles .journal-entry-wrapper:gt(1)").remove(); // modify Read More tag $('.journal-read-more-tag a:contains(Click to read more ...)').each(function(){ var str = $(this).html(); $(this).html(str.replace('Click to read more ...','Continue reading—')); }); $.swapImage(".swapImage"); }); // load recent videos $("#LoadRecentVideos").load("/articles/category/video .list-journal-entry-wrapper", function(){ //callback... $("#LoadRecentVideos .journal-entry-wrapper:gt(1)").remove(); $('<div class="VideoTag">—video</div>').insertBefore("#LoadRecentVideos .category-video .body img"); // modify Read More tag $('.journal-read-more-tag a:contains(Click to read more ...)').each(function(){ var str = $(this).html(); $(this).html(str.replace('Click to read more ...','Continue reading—')); }); $.swapImage(".swapImage"); }); }); --> </script> And here is a sample of the html for the images in an article entry: <a href="/articles/2010/5/6/article-title-goes-here.html"><img class="swapImage {src: '/storage/post-images/Sample2_color.jpg'}" src="/storage/post-images/Sample2_bw.jpg" /></a>

  • Tools to convert XML to HTML using XSLT

    - by armannvg
    I'm beginning to work on a project which has some extensive XML XSLT processing to render output HTML. Some changes need to be made to the XSLT and I need some tool that can help me modify it without having to run the solution every time. Something that can help me visualize the changes I'm making to the rendered HTML. I've found StylusStudio but I preferably would want a freeware that I could use
