  • transform:translateX vs transition on left property. Which has better performance? CSS

    - by JackMahoney
    I'm making a slide out menu with HTML and CSS3 - especially transitions. I would like to know what is best practice / best performance to slide a relatively positioned div horizontally. When i click a button it adds a class to my div. Which class is better? (Note I can add all the browser prefixes later and this site only targets modern browsers). //option 1 .animate{ -webkit-transition:all ease 0.3s; -webkit-transform:translateZ(200px); } //option 2 .animate{ -webkit-transition:all ease 0.3s; left:200px; } Thanks

  • .NET : Targeting the runtime

    - by contactmatt
    I'm starting to read in-depth on the .NET framework, and its Common Language Runtime. I'm reading a .NET overview by Microsoft and I'm not sure what is meant by this statement. Code that targets the runtime is known as managed code, while code that does not target the runtime is known as unmanaged code. How do you target the Common Language Runtime? I know its defaulted when developing in Visual Studio, but how would you specifically target the CLR? What code when developing a .NET application wouldn't target the CLR, and thereby be called unmanaged code?

  • Displaytag export option is not working

    - by Nirmal
    Hello All, I am using Displaytag framework for pagination & exporting purpose. In that i am also using Strut2Tiles Integration. Whenever i am calling any action class it will returning me a list & through Displaytag i am successfully displaying record on my page. For that my jsp page's code looks like : <s:set name="selectedPageSize" value="selectedPageSize" scope="request"/> <s:set value="accountList" scope="request" name="accountList"/> <display:table name="accountList" export="true" class="table" requestURI="" id="accountList" pagesize="${selectedPageSize}" > <display:setProperty name="export.pdf" value="true" /> <display:column property="id" sortable="true" class="sort-title"/> <display:column property="name" sortable="true"/> <display:column property="contactPerson" sortable="true"/> <display:column property="phone1" sortable="true"/> <display:column property="phone2" sortable="true"/> <display:column property="fax" sortable="true"/> <display:column property="email" sortable="true"/> <display:column property="webSite" sortable="true"/> <display:column property="address1" sortable="true"/> <display:column property="address2" sortable="true"/> <display:column property="countryId.name" title="Country" sortable="true"/> <display:column property="stateId.name" title="State" sortable="true"/> <display:column property="countryId.name" title="City" sortable="true"/> <display:column property="isDeleted" sortable="true"/> <display:column title="Delete"> <s:url id="removeUrl" action="finance/deleteAccount.action"> <s:param name="id" value="#attr.accountList.id" /> </s:url> <s:a href="%{removeUrl}" theme="ajax" targets="accountList">Remove</s:a> </display:column> <display:column title="Update"> <s:url id="updateUrl" action="finance/updateAccount.action"> <s:param value="#attr.accountList.id" name="id"/> </s:url> <s:a href="%{updateUrl}&action=update" targets="accountlist">Update</s:a> </display:column> Actually this page is displaying through tiles configuration. Here i have enabled the export option, so it is showing me the exporting options like CSV, EXCEL, XML. But whenver i am clicking on that CSV link, my web browser hanged, means nothing is displayed on it For that exporting solution i have also added filter in my web.xml. My web.xml looks like: <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <filter> <filter-name>ResponseOverrideFilter</filter-name> <filter-class>org.displaytag.filter.ResponseOverrideFilter</filter-class> </filter> <filter-mapping> <filter-name>ResponseOverrideFilter</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <filter-mapping> <filter-name>ResponseOverrideFilter</filter-name> <url-pattern>*.jsp</url-pattern> </filter-mapping> <listener> <listener-class>org.apache.struts2.tiles.StrutsTilesListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/webApplicationContext.xml</param-value> </context-param> <welcome-file-list> <welcome-file>jsp/welcome.jsp</welcome-file> </welcome-file-list> I have also included following list of libraries of displaytag : 1) displaytag-1.2.jar 2) displaytag-export-poi-1.2.jar 3) displaytag-portlet-1.2.jar The exception that i am getting is : 2009-05-09 12:02:38,234 DEBUG (org.displaytag.tags.TableTag:1524) - Exportfilter NOT enabled 2009-05-09 12:02:38,312 WARN (org.displaytag.tags.TableTag:63) - Exception: [.TableTag] Unable to reset response before returning exported data.

  • setting permissions of python module (python setup install)

    - by SetJmp
    I am configuring a distutils-based setup.py for a python module that is to be installed on a heterogeneous set of resources. Due to the heterogeneity, the location where the module is installed is not the same on each host however disutils picks the host-specific location. I find that the module is installed without o+rx permissions using disutils (in spite of setting umask ahead of running setup.py). One solution is to manually correct this problem, however I would like an automated means that works on heterogeneous install targets. For example, is there a way to extract the ending location of the installation from within setup.py? Any other suggestions? Thanks! SetJmp

  • WPF Menu Items Styles

    - by Allen Ho
    Hi, I have an application resource of the following <Style TargetType="{x:Type TextBlock}"> <Setter Property="Background" Value="{DynamicResource windowTextBackColor}"/> <Setter Property="Foreground" Value="{DynamicResource windowsTextForeColor}"/> </Style> So all the text blocks in my application should assume those colours. However the Menu and its containing MenuItems on my Main Window does not take these colours? I have to do the XAML for it to assume those colours, Is there a reason why setting a style that targets Text blocks does not work? Thanks

  • How to cancel drop event in YUI drag & drop utility?

    - by gk
    We are using drag & drop utility between one source and multiple targets. We have a restriction that one of the target can only have one child element while the other ones can have multiple items. I have tried subscribing dragDropEvent of the proxy item and returning false in case the destination target has multiple child elements, with out much luck. var m = new YAHOO.example.DDList("dli" + j, 'documentSelection'); m.subscribe('dragDropEvent', function(e){ if (e.info == 'ulMasterDocument' && $('#ulMasterDocument').children().length > 1){ e.event.canceBubble = true; return false; } return true; }); Is this code correct? Or do i need to subscribe some other event? Thanks

  • .NET 4.0 build issues on CI Server

    - by DMcKenna
    Anybody manage to get .net 4.0 applications compiling on a CI server without installing visual studio 2010 on a CI server. No SDK exists for .net 4.0. Have installed .NET 4.0 on CI Server. Msbuild.exe works for simple projects and give the following warning (GetReferenceAssemblyPaths target) - C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(847,9): warning MSB3644: The reference assemblies for framework ".NETFramework,Version=v4.0" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in placeof reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend.

  • Grails Testing hickups

    - by egervari
    I have two testing questions. Both are probably easily answered. The first is that I wrote this unit test in Grails: void testCount() { mockDomain(UserAccount) new UserAccount(firstName: "Ken").save() new UserAccount(firstName: "Bob").save() new UserAccount(firstName: "Dave").save() assertEquals(3, UserAccount.count()) } For some reason, I get 0 returned back. Did I forget to do something? The second question is for those who use IDEA. What should I be running - IDEA's junit tests, or grails targets? I have two options. Also, why does IDEA say that my tests pass and it provides a green light even though the test above actually fails? This will really drive me nuts if I have to check the test reports in html every time I run my tests..... Help?

  • insertNewObjectForEntityForName: inManagedObjectContext: returning NSNumber bug?

    - by beinstein
    I'm relatively well versed in CoreData and have been using it for several years with little or no difficulty. All of a sudden I'm now dumbfounded by an error. For the life of me, I can't figure out why insertNewObjectForEntityForName:inManagedObjectContext: is all of a sudden returning some sort of strange instance of NSNumber. GDB says the returned object is of the correct custom subclass of NSManagedObject, but when I go to print a description of the NSManagedObject itself, I get the following error: *** -[NSCFNumber objectID]: unrecognized selector sent to instance 0x3f26f50 What's even stranger, is that I'm able to set some relationships and attributes using setValue:forKey: and all is good. But when I try to set once specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 Has anyone ever encountered anything like this before? I've tried clean all targets, restarting everything, even changing the model to the relationship in question is a to-one instead of a to-many. Nothing makes any difference.

  • Unix makefile errors " 'ake: Fatal error: Don't know how to make (c file here)"

    - by gwenger
    I've written the below makefile: hw2p1: hw2p1_main.o hw2p1_getit.o hw2p1_parseit.o hw2p1_moveit.o hw2p1_showit.o gcc hw2p1_main.o hw2p1_getit.o hw2p1_parseit.o hw2p1_moveit.o hw2p1_showit.o hw2p1_main.o: hw2p1_main.c gcc -c hw2p1_main.c hw2p1_getit.o: hw2p1_getit.c gcc -c hw2p1_getit.c hw2p1_parseit.o: hw2p1_parseit.c gcc -c hw2p1_parseit.c hw2p1_moveit.o: hw2p1_moveit.c gcc -c hw2p1_moveit.c hw2p1_showit.o: hw2p1_showit.c gcc -c hw2p1_showit.c The first time I tried to call make, I got the error: "make: Fatal error: unexpected end of line seen" I deleted the blank lines between targets and called make again, but this time I got " 'ake: Fatal error: Don't know how to make hw2p1_main.c" I've compiled all of these files separately and then linked them so I know that the errors are a result of an incorrect makefile and not a result of errors in my c files. This is the first makefile that I've ever written so I might just be doing it completely incorrectly. Either way, any suggestions on how to get rid of these errors?

  • How to achieve a palette effect on iPhone using OpenGL

    - by Joe
    I'm porting a 2d retro game to iPhone that has the following properties: targets OpenGL ES 1.1 entire screen is filled with tiles (textured triangle strip tile textured using a single 256x256 RGBA texture image the texture is passed to OpenGL once at the start of the game only 4 displayed colours are used one of the displayed colours is black The original game flashed the screen when time starts to run out by toggling the black pixels to white using an indexed palette. What is the best (i.e. most efficient) way to achieve this in OpenGL ES 1.1? My thoughts so far: Generate an alternative texture with white instead of black pixels, and pass to OpenGL when the screen is flashing Render a white poly underneath the background and render the texture with alpha on to display it Try and render a poly on top with some blending that achieves the effect (not sure this is possible) I'm fairly new to OpenGL so I'm not sure what the performance drawbacks of each of these are, or if there's a better way of doing this.

  • Can't Add LINQ to SQL classes to projects in VS2010

    - by MisterJames
    I just ran into something in Visual Studio 2010 RC that wasn't previously happening (like, yesterday). No software changes here, but I did run into some muck yesterday when compiling that required a reboot. I am unable to add LINQ to SQL classes to any project through the add dialog. I have created ASP.NET web sites, ASP.NET MVC projects - both of these as 'templated' and as 'empty' - and there appear to be no templates installed or available. I have made sure that the project targets the 4.0 Framework. I can easily add a new database and the ADO.NET entity framework templates are there. As a workaround I can copy a DBML file to my project, delete all tables and sprocs, update the connection string and use the leftover shell (the designer works fine like this), but it's a pain. Has anyone else had their templates drop? Figured out how to reinstall them?

  • IB not responding to UIImageView moving

    - by Rudiger
    This an incredibly annoying bug. I had a imageView and 2 Labels in a customCell nib. I changed the locations of all of them in the nib and the labels moved, view didn't. I've cleaned my targets, deleted everything relating to it the library, deleted the cell completely, reset the simulator, built it on a different target (3.1.2) and it still compiles the image in the same stupid spot. Can anyone help this is nuts. Sorry for being blunt but completely frustrated. Edit: I have deleted the nib and created it over again by hand, but with the same names. Doesn't fix it. I've checked to see if im moving it somewhere in the code and no dice.

  • Data Integration/EAI Project Lessons Learned

    - by Greg Harman
    Have you worked on a significant data or application integration project? I'm interested in hearing what worked for you and what didn't and how that affected the project both during and after implementation (i.e. during ongoing operation, maintenance and expansion). In addition to these lessons learned, please describe the project by including a quick overview of: The data sources and targets. Specifics are not necessary, but I'd like to know general technology categories e.g. RDBMS table, application accessed via a proprietary socket protocol, web service, reporting tool. The overall architecture of the project as related to data flows. Different human roles in the project (was this all done by one engineer? Did it include analysts with a particular expertise?) Any third-party products utilized, commercial or open source.

  • Appcelerator Vs. MonoTouch - Which one is best for a .NET developer ?

    - by Click Ahead
    Hi All, I'm a .NET developer with 10 years experience developing Web & Mobile Apps. I'm looking to branch into iPhone (and possibly Android) development. I'm looking at two products: Appcelerator Titanium (http://www.appcelerator.com/) and MonoTouch (http://monotouch.net/) I like MonoTouch because of it's standing in the Mono development communitity and it's C#. In saying that Appcelerator looks very straight forward using HTML and Javascript and targets Android too (which is overtaking the iPhone). The apps I'm looking to develop are line of business applications with data entry, syncing with back office, etc. Can anyone give their opinion on the pro's / con's of using these tools or any experiences. I'm very interested in any thoughts ! Thanks in advance, Ciaran

  • Distributing WPF apps to a legacy user base: How seamless is it?

    - by Christian Nunciato
    I'm considering developing a WPF application, to be hosted by a legacy Windows app (C++), and I'm trying to get a better sense of how feasible it'll be to do so, given the broad user base I'm targeting. Knowing WPF targets .NET 3.5, I'm looking for some insight as to what the field looks like right now -- who's already got the runtime, whether it's distributed by Windows Update, if so, how (e.g., as an optional or required download, to which operating systems, etc.), whether XP pre-XP2 supports it (and how), and so on. The current version's got many thousands of users, using all manner of Windows operating systems, and while I'd very much like to leverage WPF to breathe some life into their user experience, I want to make sure I'm not shutting anyone out by doing so, or burdening them with a download they might have to do manually. I realize most, or all, of this information's out there already, in various places, but I figured I'd ask here first, since I'm sure some of you've probably already gone down this road and have valuable experiences to share. Thanks in advance!

  • Platform configuration for projects in VS 2010

    - by Thomas Wanner
    I have a third-party project type in Visual Studio which for some reason only supports the .NET Platform configuration for the build, for all other (standard C#) projects in the solution I only have AnyCPU. Unfortunately, ever since upgrading to VS 2010 it produces following error when built : Error 39 The OutputPath property is not set for project 'ReferencedBusinessProject.csproj'. Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Configuration='Debug' Platform='.NET'. This error may also appear if some other project is trying to follow a project-to-project reference to this project, this project has been unloaded or is not included in the solution, and the referencing project does not build using the same or an equivalent Configuration or Platform. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets 483 10 CustomTypeProject It's pretty much descriptive in what is missing but I haven't found any way to fix it so far. Do you have any idea how this can be resolved or what can be the problem ?

  • jQuery tooltips on a dynamically generated page.

    - by Kyle Sevenoaks
    Him I'm trying to add a jQuery tooltip to a dynamically generated list, the text I want to display the tooltip on is in a table, so my CSS tooltip doesn't work: CSS tooltip. I tried to add this jQuery tooltip to the page, it works on my local test page, but I think the problem has something to do with uniqur ids, and I'm not sure how to implement the bind all function explained there: "To bind all of the targets to their corresponding content, it takes only one line: $(".tooltip-target").ezpz_tooltip(); Calling ezpz_tooltip() on a class will bind the hover event to each element, and because of the naming convention it will know which content to display." Can someone help me to understand what exactly I have to do to make this work on a dynamic page? The page is Euroworker's checkout product page. (You'll have to add some items to the basket, click the home button on the left of the bnav bar and click the little white button "kjøp" then the orange button "handlevogn".) Thanks.

  • Prevent OCUnit tests from running when compilation fails

    - by mhenry1384
    I'm using Xcode 3.2.2 and the built in OCUnit test stuff. One problem I'm running into is that every time I do a build my unit tests are run, even if the build failed. Let's say I make a syntax error in one of my tests. The test fails to compile and the last successful compilation of the unit tests are run. The same thing happens if one of the dependent targets fail to build - the tests are still run. Which is obviously not what I want. How can I prevent the tests from running if the build fails? If this is not possible then I'd rather have the tests never run automatically, is that possible? Sorry if this is obvious, I'm an Xcode noob. Should I be using a better unit testing framework?

  • Which tool / technology: System management for databases and dependent services

    - by Filburt
    A follow-up on this system management question: Since I probably will not get much feedback on serverfault I'll give it a try here. My main concern is to reflect the dependencies between the databases, services ans tasks/jobs I'll have to manage. Besides considering Powershell, I even thought about using MSBuild because it would allow for modeling dependencies and reuse configuration targets. In other words: What technology should I use to develop a flexible solution that will allow me to stop service A, B and C on machine D in the right order and disable task E on machine F when taking down database X?

  • Are evolutionary algorithms and neural networks used in the same problem domains?

    - by Joe Holloway
    I am trying to get a feel for the difference between the various classes of machine-learning algorithms. I understand that the implementations of evolutionary algorithms are quite different from the implementations of neural networks. However, they both seem to be geared at determining a correlation between inputs and outputs from a potentially noisy set of training/historical data. From a qualitative perspective, are there problem domains that are better targets for neural networks as opposed to evolutionary algorithms? I've skimmed some articles that suggest using them in a complementary fashion. Is there a decent example of a use case for that? Thanks

  • How to determine if code is running in Foundation or GUI?

    - by Mitch Cohen
    I'm writing a Mac app with two targets - a regular Cocoa GUI and a Foundation command-line tool. They do very similar things other than the GUI, so I'm sharing most of the code between the two. I'd like to do a few things slightly differently depending on which target is running. I can think of many ways to do this (#define something in the pch, check for existence of GUI definitions...). I'm curious if there's a standard or recommended way to do this. Thanks!

  • Conditionally execute a task after building a solution with MSBuild + TFS

    - by SoMoS
    Hello, I'm using MSBuild with TFS and I have to build 4 solutions. When the compilation is done I should launch upon to 4 different Exec tasks depending on wherever the compilation was successful or not. I know how to do that with MSBuild alone using targets with conditions using the var $(BuildBreak) because I can do build solution - check result - exec task - build ... but I don't know how to do that with the TFS extensions ... any help will be very appreciated. Thanks mates.
