  • Scaling an image in a scroller resizes the scroller when relative dimension are set to the scroller

    - by tit
    Hi, I would like to position relatively a scroller in my application like below. When I scale the image, I resize the scroller... <s:Scroller width="50%" height="50%" > <s:Group> <mx:Image id="img" source="media/paxRomana005_150dpi.jpg" /> </s:Group> </s:Scroller> If I set absolute dimension to the scroller like below, it does not resize (behaviour I want) <s:Scroller width="400" height="400" > <s:Group> <mx:Image id="img" source="media/paxRomana005_150dpi.jpg" /> </s:Group> </s:Scroller> .. but my intention is to position the scroller relatively to other components. Any explanations/solutions? Thanks

  • Simple way of converting server side objects into client side using JSON serialization for asp.net websites

    - by anil.kasalanati
     Introduction:- With the growth of Web2.0 and the need for faster user experience the spotlight has shifted onto javascript based applications built using REST pattern or asp.net AJAX Pagerequest manager. And when we are working with javascript wouldn’t it be much better if we could create objects in an OOAD way and easily push it to the client side.  Following are the reasons why you would push the server side objects onto client side -          Easy availability of the complex object. -          Use C# compiler and rick intellisense to create and maintain the objects but use them in the javascript. You could run code analysis etc. -          Reduce the number of calls we make to the server side by loading data on the pageload.   I would like to explain about the 3rd point because that proved to be highly beneficial to me when I was fixing the performance issues of a major website. There could be a scenario where in you be making multiple AJAX based webrequestmanager calls in order to get the same response in a single page. This happens in the case of widget based framework when all the widgets are independent but they need some common information available in the framework to load the data. So instead of making n multiple calls we could load the data needed during pageload. The above picture shows the scenario where in all the widgets need the common information and then call GetData webservice on the server side. Ofcourse the result can be cached on the client side but a better solution would be to avoid the call completely.  In order to do that we need to JSONSerialize the content and send it in the DOM.                                                                                                                                                                                                                                                                                                                                                                                            Example:- I have developed a simple application to demonstrate the idea and I would explaining that in detail here. The class called SimpleClass would be sent as serialized JSON to the client side .   And this inherits from the base class which has the implementation for the GetJSONString method. You can create a single base class and all the object which need to be pushed to the client side can inherit from that class. The important thing to note is that the class should be annotated with DataContract attribute and the methods should have the Data Member attribute. This is needed by the .Net DataContractSerializer and this follows the opt-in mode so if you want to send an attribute to the client side then you need to annotate the DataMember attribute. So if I didn’t want to send the Result I would simple remove the DataMember attribute. This is default WCF/.Net 3.5 stuff but it provides the flexibility of have a fullfledged object on the server side but sending a smaller object to the client side. Sometimes you may hide some values due to security constraints. And thing you will notice is that I have marked the class as Serializable so that it can be stored in the Session and used in webfarm deployment scenarios. Following is the implementation of the base class –  This implements the default DataContractJsonSerializer and for more information or customization refer to following blogs – http://softcero.blogspot.com/2010/03/optimizing-net-json-serializing-and-ii.html http://weblogs.asp.net/gunnarpeipman/archive/2010/12/28/asp-net-serializing-and-deserializing-json-objects.aspx The next part is pretty simple, I just need to inject this object into the aspx page.   And in the aspx markup I have the following line – <script type="text/javascript"> var data =(<%=SimpleClassJSON  %>);   alert(data.ResultText); </script>   This will output the content as JSON into the variable data and this can be any element in the DOM. And you can verify the element by checking data in the Firebug console.    Design Consideration – If you have a lot of javascripts then you need to think about using Script # and you can write javascript in C#. Refer to Nikhil’s blog – http://projects.nikhilk.net/ScriptSharp Ensure that you are taking security into consideration while exposing server side objects on to client side. I have seen application exposing passwords, secret key so it is not a good practice.   The application can be tested using the following url – http://techconsulting.vpscustomer.com/Samples/JsonTest.aspx The source code is available at http://techconsulting.vpscustomer.com/Source/HistoryTest.zip

  • Sharing business logic between server-side and client-side of web application?

    - by thoughtpunch
    Quick question concerning shared code/logic in back and front ends of a web application. I have a web application (Rails + heavy JS) that parses metadata from HTML pages fetched via a user supplied URL (think Pinterest or Instapaper). Currently this processing takes place exclusively on the client-side. The code that fetches the URL and parses the DOM is in a fairly large set of JS scripts in our Rails app. Occasionally want to do this processing on the server-side of the app. For example, what if a user supplied a URL but they have JS disabled or have a non-standard compliant browser, etc. Ideally I'd like to be able to process these URLS in Ruby on the back-end (in asynchronous background jobs perhaps) using the same logic that our JS parsers use WITHOUT porting the JS to Ruby. I've looked at systems that allow you to execute JS scripts in the backend like execjs as well as Ruby-to-Javascript compilers like OpalRB that would hopefully allow "write-once, execute many", but I'm not sure that either is the right decision. Whats the best way to avoid business logic duplication for apps that need to do both client-side and server-side processing of similar data?

  • .NET4: In-Process Side-by-Side Execution Explained

    - by emptyset
    Overview: I'm interested in learning more about the .NET4 "In-Process Side-by-Side Execution" of assemblies, and need additional information to help me demystify it. Motivation: The application in question is built against .NET2, and uses two third-party libraries that also work against .NET2. The application is deployed (via file copy) to client machines in a virtual environment that includes .NET2. Not my architecture, please bear with me. Goal: To see if it's possible to rebuild the application assemblies (or a subset) against .NET4, and ship the application as before, without changing the third-party libraries and including the .NET4 Client Profile (as described here) in the deployment. Steps Taken: The following articles were read, but didn't quite provide me enough information: In-Process Side-by-Side Execution: Browsed this article, and Scenario Two is the closest it comes to describing something that resembles my situation, but doesn't really cover it with any depth. ASP.NET Side-by-Side Execution Overview: This article covers a web application, but I'm dealing with a client WinForms application. CLR Team Blog: In-Process Side-by-Side: This is useful to explain how plug-ins to host processes function under .NET4, but I don't know if this applies to the third-party libraries. Further Steps: I'm also unclear on how to proceed upgrading a single .NET2 assembly to .NET4, with the overall application remaining in .NET2 (i.e. how to configure the solution/project files, if any special code needs to be included, etc.).

  • Implementing camera for 2d side scroller game ?

    - by Mr.Gando
    Hello, I'm implementing a 2D side scroller for iOS (using C/C++ with OpenGL) (beat'em up style like double dragon/final fight ). My scenes are composed of one cyclical background image ( the end of the image connects perfectly with the beginning ). This is to produce a cyclical scroll effect. I was wondering how could I implement a camera that follows my player movement ? ( Resources / Links are greatly appreciated with explanations :) )

  • How to create a simple side scroller game

    - by D34thSt4lker
    I'm still pretty new to game programming and any tutorial that I have worked with stuck to only games with the initial screen. I want to start creating my own games but there are a few things that I still need to learn. One of them is how to create a game that side-scrolls. For example; Mario... Or ANY type of game like that... Can anyone give me a small example to create something like that. I'm not asking for any specific language because currently in school I am learning javascript but I know some c++/java/processing/objective-c as well. So any of those languages would be fine and I could probably implement it in any of the others... I have been searching for some help with this for a while now but could never actually get any help on it. Thanks in advance!

  • FSharp.Compiler.CodeDom for VS2008 and VS2010 side-by-side

    - by SztupY
    I'm using FSharp.Compiler.CodeDom to dynamically create F# classes. The problem is, that I have both VS2008 and VS2010 on my computer side-by-side (they works fine), and using F# in this configuration is buggy at best: If I don't install InstallFSharp.msi, then under VS2008 the built classes complain about not finding FSharp.Core (even if they're referenced) If I install InstallFSharp.msi, then under VS2008 the built classes will use the F# built for VS2010, and will throw a binary-incompatibility exception, because it will load the .net4 variant: FSC: error FS0219: The referenced or default base CLI library 'mscorlib' is binary- incompatible with the referenced F# core library 'C:\Program Files (x86)\Microsoft F#\v4.0\FSharp.Core.dll'. Consider recompiling the library or making an explicit reference to a version of this library that matches the CLI version you are using. If I replace the F# found at the previous location to the separately installed dll-s, then of course VS2010 will complain about binary-incompatibility Am I overlooking something, or they won't simply work for a shared environment like this? This might mean real problems when I deploy the applications. Thanks

  • Side by side madness - running binaries on different computer (with a twist)

    - by sbk
    Here's my configuration: Computer A - Windows 7, MS Visual Studio 2005 patched for Win7 compatibility (8.0.50727.867) Computer B - Windows XP SP2, MS Visual Studio 2005 installed (8.0.50727.42) My project has some external dependencies (prebuilt DLLs - either build on A or downloaded from the Internet), a couple of DLLs built from sources and one executable. I am mostly developing on A and all is fine there. At some point I try to build my project on computer B, copying the prebuilt DLLs to the output folder. Everything builds fine, but trying to start my application I get The application failed to initialize properly (0xc0150002).... The event log contains two of those: Dependent Assembly Microsoft.VC80.CRT could not be found and Last Error was The referenced assembly is not installed on your system. plus the slightly more amusing Generate Activation Context failed for some.dll. Reference error message: The operation completed successfully. At this point I'm trying my Google-Fu, but in vain - virtually all hits are about running binaries on machines without Visual Studio installed. In my case, however, the executables fail to run on the computer they are built. Next step was to try dependency walker and it baffled me even more - my DLLs built from sources on the same box cannot find MSVCR80.DLL and MSVCP80.DLL, however the executable seems to be alright in respect to those two DLLs i.e. when I open the executable with dependency walker it shows that the MSVC?80.DLLs can be found, but when I open one of my DLLs it says they cannot. That's where I am completely out of ideas what to do so I'm asking you, dear stackoverflow :) I admit I'm a bit blurry on the whole side-by-side thing, so general reading on the topic will also be appreciated.

  • 2D Side Scrolling game and "walk over ground" collision detection

    - by Fire-Dragon-DoL
    The question is not hard, I'm writing a game engine for 2D side scrolling games, however I'm thinking to my 2D side scrolling game and I always come up with the problem of "how should I do collision with the ground". I think I couldn't handle the collision with ground (ground for me is "where the player walk", so something heavily used) in a per-pixel way, and I can't even do it with simple shape comparison (because the ground can be tilted), so what's the correct way? I'know what tiles are and i've read about it, but how much should be big each tile to not appear like a stairs?Are there any other approach? I watched this game and is very nice how he walks on ground: http://www.youtube.com/watch?v=DmSAQwbbig8&feature=player_embedded If there are "platforms" in mid air, how should I handle them?I can walk over them but I can't pass "inside". Imagine a platform in mid air, it allows you to walk over it but limit you because you can't jump in the area she fits Sorry for my english, it's not my native language and this topic has a lot of keywords I don't know so I have to use workarounds Thanks for any answer Additional informations and suggestions: I'm doing a game course in this period and I asked them how to do this, they suggested me this approach (a QuadTree): -All map is divided into "big nodes" -Each bigger node has sub nodes, to find where the player is -You can find player's node with a ray on player position -When you find the node where the player is, you can do collision check through all pixels (which can be 100-200px nothing more) Here is an example, however i didn't show very well the bigger nodes because i'm not very good with photoshop :P How is this approach?

  • Procedurally generated 2d terrain for side scroller on Sega Genesis hardware?

    - by DJCouchyCouch
    I'm working on the Sega Genesis that has a 8mhz Motorola 68000 CPU. Any ideas on how to generate fast and decent 2d tile terrain for a side scroller in real time? The game would generate new columns or rows depending on the direction the player is scrolling in. The generation would have to be deterministic. The same seed value would generate the same terrain. I'm looking for algorithms that would satisfy the memory and CPU constraints of the hardware.

  • Drawing visible tiles - side scrolling

    - by Troubleshoot
    Currently I'm calling drawMap every time repaint is called. This is the code I've written for my drawMap method so far. public void drawMap(Graphics2D g2d) { float cameraX = Player.getX() - (Frame.CANVAS_WIDTH / 2); float cameraY = Player.getY() - (Frame.CANVAS_HEIGHT / 2); int tileX = (int) cameraX; int tileY = (int) cameraY; int xIndent = 0, yIndent = 0; int a = 0, b = 0; while (tileX % TILE_SIZE != 0) { tileX--; xIndent++; } while (tileY % TILE_SIZE != 0) { tileY--; yIndent++; } for (int y = tileY; y < tileY + Frame.CANVAS_HEIGHT; y += Map.TILE_SIZE) { for (int x = tileX; x < tileX + Frame.CANVAS_WIDTH; x += Map.TILE_SIZE) { if ((y / TILE_SIZE < 0 || x / TILE_SIZE < 0) || (y / TILE_SIZE > columnSize)) break; g2d.drawImage(map[y / TILE_SIZE][x / TILE_SIZE], a - xIndent, b - yIndent, null); a += TILE_SIZE; } a = 0; b += TILE_SIZE; } } The idea behind this is that it gets the camera position and draws the map relative to the player position. However, instead of the player being in the center of the screen all the time, the player actually moves away from the center as it scrolls to the right, and moves towards to center as it scrolls to the left. I've been trying to pinpoint what I've done wrong but I can't seem to find it. My code also seems quite messy, so am I doing this the correct way?

  • How do I deal with the problems of a fast side-scroller?

    - by Ska
    I'm making a side scrolling airplane game and when I begin going very fast I begin to experience some problems as a player: Elements are not distinguishable, like power-ups from bullets, etc I start to feel dizzy and uncomfortable There isn't enough time to see what's coming How can I sort this out? Do I use less details in all the grahpics? Tiny Wings has the same horizontal movement speed as in my game but it doesn't suffer from these problems. Are there any other really fast side-scrollers I could take as a reference?

  • Getting 2D Platformer entity collision Response Correct (side-to-side + jumping/landing on heads)

    - by jbrennan
    I've been working on a 2D (tile based) 2D platformer for iOS and I've got basic entity collision detection working, but there's just something not right about it and I can't quite figure out how to solve it. There are 2 forms of collision between player entities as I can tell, either the two players (human controlled) are hitting each other side-to-side (i. e. pushing against one another), or one player has jumped on the head of the other player (naturally, if I wanted to expand this to player vs enemy, the effects would be different, but the types of collisions would be identical, just the reaction should be a little different). In my code I believe I've got the side-to-side code working: If two entities press against one another, then they are both moved back on either side of the intersection rectangle so that they are just pushing on each other. I also have the "landed on the other player's head" part working. The real problem is, if the two players are currently pushing up against each other, and one player jumps, then at one point as they're jumping, the height-difference threshold that counts as a "land on head" is passed and then it registers as a jump. As a life-long player of 2D Mario Bros style games, this feels incorrect to me, but I can't quite figure out how to solve it. My code: (it's really Objective-C but I've put it in pseudo C-style code just to be simpler for non ObjC readers) void checkCollisions() { // For each entity in the scene, compare it with all other entities (but not with one it's already compared against) for (int i = 0; i < _allGameObjects.count(); i++) { // GameObject is an Entity GEGameObject *firstGameObject = _allGameObjects.objectAtIndex(i); // Don't check against yourself or any previous entity for (int j = i+1; j < _allGameObjects.count(); j++) { GEGameObject *secondGameObject = _allGameObjects.objectAtIndex(j); // Get the collision bounds for both entities, then see if they intersect // CGRect is a C-struct with an origin Point (x, y) and a Size (w, h) CGRect firstRect = firstGameObject.collisionBounds(); CGRect secondRect = secondGameObject.collisionBounds(); // Collision of any sort if (CGRectIntersectsRect(firstRect, secondRect)) { //////////////////////////////// // // // Check for jumping first (???) // // //////////////////////////////// if (firstRect.origin.y > (secondRect.origin.y + (secondRect.size.height * 0.7))) { // the top entity could be pretty far down/in to the bottom entity.... firstGameObject.didLandOnEntity(secondGameObject); } else if (secondRect.origin.y > (firstRect.origin.y + (firstRect.size.height * 0.7))) { // second entity was actually on top.... secondGameObject.didLandOnEntity.(firstGameObject); } else if (firstRect.origin.x > secondRect.origin.x && firstRect.origin.x < (secondRect.origin.x + secondRect.size.width)) { // Hit from the RIGHT CGRect intersection = CGRectIntersection(firstRect, secondRect); // The NUDGE just offsets either object back to the left or right // After the nudging, they are exactly pressing against each other with no intersection firstGameObject.nudgeToRightOfIntersection(intersection); secondGameObject.nudgeToLeftOfIntersection(intersection); } else if ((firstRect.origin.x + firstRect.size.width) > secondRect.origin.x) { // hit from the LEFT CGRect intersection = CGRectIntersection(firstRect, secondRect); secondGameObject.nudgeToRightOfIntersection(intersection); firstGameObject.nudgeToLeftOfIntersection(intersection); } } } } } I think my collision detection code is pretty close, but obviously I'm doing something a little wrong. I really think it's to do with the way my jumps are checked (I wanted to make sure that a jump could happen from an angle (instead of if the falling player had been at a right angle to the player below). Can someone please help me here? I haven't been able to find many resources on how to do this properly (and thinking like a game developer is new for me). Thanks in advance!

  • Running ASP.NET Webforms and ASP.NET MVC side by side

    - by rajbk
    One of the nice things about ASP.NET MVC and its older brother ASP.NET WebForms is that they are both built on top of the ASP.NET runtime environment. The advantage of this is that, you can still run them side by side even though MVC and WebForms are different frameworks. Another point to note is that with the release of the ASP.NET routing in .NET 3.5 SP1, we are able to create SEO friendly URLs that do not map to specific files on disk. The routing is part of the core runtime environment and therefore can be used by both WebForms and MVC. To run both frameworks side by side, we could easily create a separate folder in your MVC project for all our WebForm files and be good to go. What this post shows you instead, is how to have an MVC application with WebForm pages  that both use a common master page and common routing for SEO friendly URLs.  A sample project that shows WebForms and MVC running side by side is attached at the bottom of this post. So why would we want to run WebForms and MVC in the same project?  WebForms come with a lot of nice server controls that provide a lot of functionality. One example is the ReportViewer control. Using this control and client report definition files (RDLC), we can create rich interactive reports (with charting controls). I show you how to use the ReportViewer control in a WebForm project here :  Creating an ASP.NET report using Visual Studio 2010. We can create even more advanced reports by using SQL reporting services that can also be rendered by the ReportViewer control. Now, consider the sample MVC application I blogged about called ASP.NET MVC Paging/Sorting/Filtering using the MVCContrib Grid and Pager. Assume you were given the requirement to add a UI to the MVC application where users could interact with a report and be given the option to export the report to Excel, PDF or Word. How do you go about doing it?   This is a perfect scenario to use the ReportViewer control and RDLCs. As you saw in the post on creating the ASP.NET report, the ReportViewer control is a Web Control and is designed to be run in a WebForm project with dependencies on, amongst others, a ScriptManager control and the beloved Viewstate.  Since MVC and WebForm both run under the same runtime, the easiest thing to is to add the WebForm application files (index.aspx, rdlc, related class files) into our MVC project. You can copy the files over from the WebForm project into the MVC project. Create a new folder in our MVC application called CommonReports. Add the index.aspx and rdlc file from the Webform project   Right click on the Index.aspx file and convert it to a web application. This will add the index.aspx.designer.cs file (this step is not required if you are manually adding a WebForm aspx file into the MVC project).    Verify that all the type names for the ObjectDataSources in code behind to point to the correct ProductRepository and fix any compiler errors. Right click on Index.aspx and select “View in browser”. You should see a screen like the one below:   There are two issues with our page. It does not use our site master page and the URL is not SEO friendly. Common Master Page The easiest way to use master pages with both MVC and WebForm pages is to have a common master page that each inherits from as shown below. The reason for this is most WebForm controls require them to be inside a Form control and require ControlState or ViewState. ViewMasterPages used in MVC, on the other hand, are designed to be used with content pages that derive from ViewPage with Viewstate turned off. By having a separate master page for MVC and WebForm that inherit from the Root master page,, we can set properties that are specific to each. For example, in the Webform master, we can turn on ViewState, add a form tag etc. Another point worth noting is that if you set a WebForm page to use a MVC site master page, you may run into errors like the following: A ViewMasterPage can be used only with content pages that derive from ViewPage or ViewPage<TViewItem> or Control 'MainContent_MyButton' of type 'Button' must be placed inside a form tag with runat=server. Since the ViewMasterPage inherits from MasterPage as seen below, we make our Root.master inherit from MasterPage, MVC.master inherit from ViewMasterPage and Webform.master inherits from MasterPage. We define the attributes on the master pages like so: Root.master <%@ Master Inherits="System.Web.UI.MasterPage"  … %> MVC.master <%@ Master MasterPageFile="~/Views/Shared/Root.Master" Inherits="System.Web.Mvc.ViewMasterPage" … %> WebForm.master <%@ Master MasterPageFile="~/Views/Shared/Root.Master" Inherits="NorthwindSales.Views.Shared.Webform" %> Code behind: public partial class Webform : System.Web.UI.MasterPage {} We make changes to our reports aspx file to use the Webform.master. See the source of the master pages in the sample project for a better understanding of how they are connected. SEO friendly links We want to create SEO friendly links that point to our report. A request to /Reports/Products should render the report located in ~/CommonReports/Products.aspx. Simillarly to support future reports, a request to /Reports/Sales should render a report in ~/CommonReports/Sales.aspx. Lets start by renaming our index.aspx file to Products.aspx to be consistent with our routing criteria above. As mentioned earlier, since routing is part of the core runtime environment, we ca easily create a custom route for our reports by adding an entry in Global.asax. public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}");   //Custom route for reports routes.MapPageRoute( "ReportRoute", // Route name "Reports/{reportname}", // URL "~/CommonReports/{reportname}.aspx" // File );     routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); } With our custom route in place, a request to Reports/Employees will render the page at ~/CommonReports/Employees.aspx. We make this custom route the first entry since the routing system walks the table from top to bottom, and the first route to match wins. Note that it is highly recommended that you write unit tests for your routes to ensure that the mappings you defined are correct. Common Menu Structure The master page in our original MVC project had a menu structure like so: <ul id="menu"> <li> <%=Html.ActionLink("Home", "Index", "Home") %></li> <li> <%=Html.ActionLink("Products", "Index", "Products") %></li> <li> <%=Html.ActionLink("Help", "Help", "Home") %></li> </ul> We want this menu structure to be common to all pages/views and hence should reside in Root.master. Unfortunately the Html.ActionLink helpers will not work since Root.master inherits from MasterPage which does not have the helper methods available. The quickest way to resolve this issue is to use RouteUrl expressions. Using  RouteUrl expressions, we can programmatically generate URLs that are based on route definitions. By specifying parameter values and a route name if required, we get back a URL string that corresponds to a matching route. We move our menu structure to Root.master and change it to use RouteUrl expressions: <ul id="menu"> <li> <asp:HyperLink ID="hypHome" runat="server" NavigateUrl="<%$RouteUrl:routename=default,controller=home,action=index%>">Home</asp:HyperLink></li> <li> <asp:HyperLink ID="hypProducts" runat="server" NavigateUrl="<%$RouteUrl:routename=default,controller=products,action=index%>">Products</asp:HyperLink></li> <li> <asp:HyperLink ID="hypReport" runat="server" NavigateUrl="<%$RouteUrl:routename=ReportRoute,reportname=products%>">Product Report</asp:HyperLink></li> <li> <asp:HyperLink ID="hypHelp" runat="server" NavigateUrl="<%$RouteUrl:routename=default,controller=home,action=help%>">Help</asp:HyperLink></li> </ul> We are done adding the common navigation to our application. The application now uses a common theme, routing and navigation structure. Conclusion We have seen how to do the following through this post Add a WebForm page from a WebForm project to an existing ASP.NET MVC application Use a common master page for both WebForm and MVC pages Use routing for SEO friendly links Use a common menu structure for both WebForm and MVC. The sample project is attached below. Version: VS 2010 RTM Remember to change your connection string to point to your Northwind database NorthwindSalesMVCWebform.zip

  • Upgrade Office 2003 to 2010 on XP or Run them Side by Side

    - by Mysticgeek
    If you’re still running XP, currently have Office 2003 installed on your machine, and skipped Office 2007, you might want to upgrade to Office 2010. In this guide we will show you the upgrade process or how to run them side by side. In this example we are upgrading from Office 2003 Standard to Office Professional Plus 2010 RTM (Final) on XP Professional. System Requirements To run Office 2010 on your XP machine you have to make sure you have Service Pack 3 and Microsoft Silverlight installed (links below). Or you can just install them through Windows Update. Recommended Hardware 1GHZ CPU or higher 512 MB of RAM or higher 1024×768 Resolution or higher DirectX 9.0c compatible graphics card with 64 MB of memory or higher Installing Office 2010 Simply kick off the Office Professional Plus 2010 installation. Enter in your product key… Agree to the EULA…   Select the Customize button… Setup will detect Office 2003 and allow you to remove all applications, keep them, or select only the ones you want to keep. In this example we’re going to remove Excel and PowerPoint, and keep Outlook and Word 2003. Next, click the Installation Options tab and select Office programs you want to install. Since we’re keeping Outlook 2003 and don’t want to use Outlook 2010, we’re making sure not to install Outlook 2010. However, we want to run Word 2003 and 2010 on the same machine. After you’ve made your selections click the Upgrade button. The installation begins and you’re shown the progress. The amount of time it takes to install will vary between systems. Installation is complete and you can close out of the installer. Now when you go into the Start menu under Microsoft Office, you’ll see both versions of the Office apps available. Here is a shot of Word 2003 and 2010 running together on our XP machine.   Conclusion If you’re moving from Office 2003 to 2010, this allows you to install both versions side by side. It gives you a chance to learn 2010 features, and still work in the familiar 2003 environment when you need to get things done quickly. If you’re having problems installing Office 2010 make sure to check out our article on how to fix problems upgrading Office 2010 beta to RTM (Final) release. Also, if you were using Office 2007 and are currently using the 2010 beta, we have a guide on how to switch back to Office 2007 after the 2010 beta ends.

  • Unobtrusive Client Side Validation with Dynamic Contents in ASP.NET MVC 3

    - by imran_ku07
        Introduction:          A while ago, I blogged about how to perform client side validation for dynamic contents in ASP.NET MVC 2 at here. Using the approach given in that blog, you can easily validate your dynamic ajax contents at client side. ASP.NET MVC 3 also supports unobtrusive client side validation in addition to ASP.NET MVC 2 client side validation for backward compatibility. I feel it is worth to rewrite that blog post for ASP.NET MVC 3 unobtrusive client side validation. In this article I will show you how to do this.       Description:           I am going to use the same example presented at here. Create a new ASP.NET MVC 3 application. Then just open HomeController.cs and add the following code,   public ActionResult CreateUser() { return View(); } [HttpPost] public ActionResult CreateUserPrevious(UserInformation u) { return View("CreateUserInformation", u); } [HttpPost] public ActionResult CreateUserInformation(UserInformation u) { if(ModelState.IsValid) return View("CreateUserCompanyInformation"); return View("CreateUserInformation"); } [HttpPost] public ActionResult CreateUserCompanyInformation(UserCompanyInformation uc, UserInformation ui) { if (ModelState.IsValid) return Content("Thank you for submitting your information"); return View("CreateUserCompanyInformation"); }             Next create a CreateUser view and add the following lines,   <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<UnobtrusiveValidationWithDynamicContents.Models.UserInformation>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> CreateUser </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <div id="dynamicData"> <%Html.RenderPartial("CreateUserInformation"); %> </div> </asp:Content>             Next create a CreateUserInformation partial view and add the following lines,   <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<UnobtrusiveValidationWithDynamicContents.Models.UserInformation>" %> <% Html.EnableClientValidation(); %> <%using (Html.BeginForm("CreateUserInformation", "Home")) { %> <table id="table1"> <tr style="background-color:#E8EEF4;font-weight:bold"> <td colspan="3" align="center"> User Information </td> </tr> <tr> <td> First Name </td> <td> <%=Html.TextBoxFor(a => a.FirstName)%> </td> <td> <%=Html.ValidationMessageFor(a => a.FirstName)%> </td> </tr> <tr> <td> Last Name </td> <td> <%=Html.TextBoxFor(a => a.LastName)%> </td> <td> <%=Html.ValidationMessageFor(a => a.LastName)%> </td> </tr> <tr> <td> Email </td> <td> <%=Html.TextBoxFor(a => a.Email)%> </td> <td> <%=Html.ValidationMessageFor(a => a.Email)%> </td> </tr> <tr> <td colspan="3" align="center"> <input type="submit" name="userInformation" value="Next"/> </td> </tr> </table> <%} %> <script type="text/javascript"> $("form").submit(function (e) { if ($(this).valid()) { $.post('<%= Url.Action("CreateUserInformation")%>', $(this).serialize(), function (data) { $("#dynamicData").html(data); $.validator.unobtrusive.parse($("#dynamicData")); }); } e.preventDefault(); }); </script>             Next create a CreateUserCompanyInformation partial view and add the following lines,   <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<UnobtrusiveValidationWithDynamicContents.Models.UserCompanyInformation>" %> <% Html.EnableClientValidation(); %> <%using (Html.BeginForm("CreateUserCompanyInformation", "Home")) { %> <table id="table1"> <tr style="background-color:#E8EEF4;font-weight:bold"> <td colspan="3" align="center"> User Company Information </td> </tr> <tr> <td> Company Name </td> <td> <%=Html.TextBoxFor(a => a.CompanyName)%> </td> <td> <%=Html.ValidationMessageFor(a => a.CompanyName)%> </td> </tr> <tr> <td> Company Address </td> <td> <%=Html.TextBoxFor(a => a.CompanyAddress)%> </td> <td> <%=Html.ValidationMessageFor(a => a.CompanyAddress)%> </td> </tr> <tr> <td> Designation </td> <td> <%=Html.TextBoxFor(a => a.Designation)%> </td> <td> <%=Html.ValidationMessageFor(a => a.Designation)%> </td> </tr> <tr> <td colspan="3" align="center"> <input type="button" id="prevButton" value="Previous"/>   <input type="submit" name="userCompanyInformation" value="Next"/> <%=Html.Hidden("FirstName")%> <%=Html.Hidden("LastName")%> <%=Html.Hidden("Email")%> </td> </tr> </table> <%} %> <script type="text/javascript"> $("#prevButton").click(function () { $.post('<%= Url.Action("CreateUserPrevious")%>', $($("form")[0]).serialize(), function (data) { $("#dynamicData").html(data); $.validator.unobtrusive.parse($("#dynamicData")); }); }); $("form").submit(function (e) { if ($(this).valid()) { $.post('<%= Url.Action("CreateUserCompanyInformation")%>', $(this).serialize(), function (data) { $("#dynamicData").html(data); $.validator.unobtrusive.parse($("#dynamicData")); }); } e.preventDefault(); }); </script>             Next create a new class file UserInformation.cs inside Model folder and add the following code,   public class UserInformation { public int Id { get; set; } [Required(ErrorMessage = "First Name is required")] [StringLength(10, ErrorMessage = "First Name max length is 10")] public string FirstName { get; set; } [Required(ErrorMessage = "Last Name is required")] [StringLength(10, ErrorMessage = "Last Name max length is 10")] public string LastName { get; set; } [Required(ErrorMessage = "Email is required")] [RegularExpression(@"^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$", ErrorMessage = "Email Format is wrong")] public string Email { get; set; } }             Next create a new class file UserCompanyInformation.cs inside Model folder and add the following code,    public class UserCompanyInformation { public int UserId { get; set; } [Required(ErrorMessage = "Company Name is required")] [StringLength(10, ErrorMessage = "Company Name max length is 10")] public string CompanyName { get; set; } [Required(ErrorMessage = "CompanyAddress is required")] [StringLength(50, ErrorMessage = "Company Address max length is 50")] public string CompanyAddress { get; set; } [Required(ErrorMessage = "Designation is required")] [StringLength(50, ErrorMessage = "Designation max length is 10")] public string Designation { get; set; } }            Next add the necessary script files in Site.Master,   <script src="<%= Url.Content("~/Scripts/jquery-1.4.4.min.js")%>" type="text/javascript"></script> <script src="<%= Url.Content("~/Scripts/jquery.validate.min.js")%>" type="text/javascript"></script> <script src="<%= Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")%>" type="text/javascript"></script>            Now run this application. You will get the same behavior as described in this article. The key important feature to note here is the $.validator.unobtrusive.parse method, which is used by ASP.NET MVC 3 unobtrusive client side validation to initialize jQuery validation plug-in to start the client side validation process. Another important method to note here is the jQuery.valid method which return true if the form is valid and return false if the form is not valid .       Summary:          There may be several occasions when you need to load your HTML contents dynamically. These dynamic HTML contents may also include some input elements and you need to perform some client side validation for these input elements before posting thier values to server. In this article I shows you how you can enable client side validation for dynamic input elements in ASP.NET MVC 3. I am also attaching a sample application. Hopefully you will enjoy this article too.   SyntaxHighlighter.all()

  • I don't understand the definition of side effects

    - by Chris Okyen
    I don't understand the wikipedia article on Side Effects: In computer science, a function or expression is said to have a side effect if, in addition to returning a value, it also 1.) Modifies some state or 2.) Has an observable interaction with calling functions or the outside world. I know an example of the first thing that causes a function or expression to have side effects - modifying a state Function and Expression modifying a state : 1.) foo(int X) { return x = x % x; } a = a + 1; What does 2.) - Has an observable interaction with calling functions or the outside world," mean? - Please give an example. The article continues on to say, "For example, a function might modify a global or static variable, modify one of its arguments, raise an exception, write data to a display or file, read data, or call other side-effecting functions...." Are all these examples, examples of 1.) - Modifiying some state , or are they also part of 2.) - Has an observable interaction with calling functions or the outside world?
