• .NET Micro Edition - Open Multiple Windows

  - by RM

  I've had a look through quite a few tutorials, but cant seem to find how to open multipe windows? I'm not expecting to have them layer etc, I just want to define multiple window classes and say, from a menu, launch the appropriate window class from the menu window. Then when that window is finished, call the close method on it and menu will show again. I have managed to do the same kind of functionality using panels, but think window is really what I should be using? (.NET MF 4.0) I assume you can do this? I think im missing something obvious?

• How does SWTBOT run a custom eclipse based application? I don't know how to specify my target application

  - by jlisam13

  I have an eclipse based application. I have heard of swtbot however I am having a hard time understanding how exactly does this tool run my application and how would I specify that. This eclipse based application has an executable and various configuration/plugin/features files. I have done the tutorials about swtbot and I have successfully completed them but they all just create a template application to test on. Is this even possible? If not do you guys have any alternatives for UI automation testing on eclipse based apps? Thanks.

  - by user1054319

  I am trying to do the notepad tutorials and keep getting this error. I am following all the directions on the website.

I am trying to create a new Android project from source with 2.1... I have been told to uninstall Eclipse. Any help would be appreciated. Thank you

• Using Regular Expressions

  - by bebeTech

  I am having problems trying to use the regular expression that I used in JavaScript. On a web page, you may have: <b>Renewal Date:</b> 03 May 2010</td> I just want to be able to pull out the 03 May 2010, remembering that a webpage has more than just the above content. The way I currently perform this using JavaScript is: DateStr = /<b>Renewal Date:<\/b>(.+?)<\/td>/.exec(returnedHTMLPage); I tried to follow some tutorials on java.util.regex.Pattern and java.util.regex.Matcher with no luck. I can't seem to be able to translate (.+?) into something they can understand?? thanks, Noeneel

• How to use CSS3 to animate parts of an image

  - by Sang Froid

  I'd like to create an image slider with some cool 3d effects, such as this one: http://tympanus.net/codrops/2011/09/05/slicebox-3d-image-slider/ The thing is, while I know how to use CSS3 3D transforms to rotate something, I don't know how to animate "parts" of an image. In the link above, the script seems to somehow "slice" the image into several pieces, and then animate those separately. However, the image was not sliced up beforehand - it is one whole image. Can anyone recommend any tutorials on how to achieve this effect, or perhaps just give the name of whatever technique was used to do this? Thank you in advance!

• while loop / string input not working java

  - by Mikeecb

  I have looked online and all of the tutorials / questions have pointed me to this. I can't see why this isn't working. Any help would be much appreciated. Thanks import java.util.*; public class test { static Scanner userInput = new Scanner(System.in); public static void main(String[] args) { String textEntered = userInput.next(); if (textEntered == "hello") { System.out.println("Hello to you too!"); } } } I enter "hello" but nothing is printed. Also I have tried next() and nextLine();

• Is there a way to have one project build another in Visual Studio?

  - by Martin Neal

  We are finally getting a source control system in place at work and I've been in charge of setting it up. I've read that it's usually good practice to not include binaries in source control so I haven't. However, we have two all-purpose utility projects (each in their own solution) that generate utility .dll's which are included in almost all of our other projects (all each in their own separate solutions). We add references to the utility dll from our projects. I would like to have our solutions set up in such a way that if the reference dll isn't built, the solution will build the dll for itself, much in the same way a make file checks for its dependencies and builds them when they're out of date or missing. I'm new to build processes with VS so try to keep the answers simple. Any links to general build process overview tutorials would be great too. Googleing for VS references returns a bunch of how-to add references links which is not exactly what I want.

• OpenGL in Visual studio - Issues with GLEW

  - by BalsamicVinegar

  I'm currently following the openglbook.com tutorials (set up) (Tutorial) and have run into an issue fairly early on. I'm getting the following two errors: 1>main.obj : error LNK2019: unresolved external symbol __imp__glewGetErrorString@4 referenced in function _Initialize 1>main.obj : error LNK2019: unresolved external symbol __imp__glewInit@0 referenced in function _Initialize I have downloaded and compiled freeglut 2.8.0 as well as the glew 1.9.0 binaries. I have copied the libs and includes to C:\Program Files (x86)\Microsoft SDKs\Windows\v6.0A\Lib and Include respectively. The Lib and Include paths have also been added to my project properties under Additional Library/Include directories. I have also defined glew32.lib and freeglut.lib in my linker-Input-Additional dependencies. I have included and at the top of my main file. What am I missing? Every other thread I've found has been solved by adding the directories to the project properties. Does anyone have any ideas?

• Learning to work with audio in C++

  - by Skilldrick

  My degree was in audio engineering, but I'm fairly new to programming. I'd like to learn how to work with audio in a programming environment, partly so I can learn C++ better through interesting projects. First off, is C++ the right language for this? Is there any reason I shouldn't be using it? I've heard of Soundfile and some other libraries - what would you recommend? Finally, does anyone know of any good tutorials in this subject? I've learnt the basics of DSP - I just want to program it! EDIT: I use Windows. I'd like to play about with real-time stuff, a bit like Max/MSP but with more control.

• How to make a slide gesture in a view?

  - by AedonEtLIRA

  I have a grid layout that holds a limited 6 items per screen. This set number is just a base for the app and make it look and feel better so it must stay set to that. To get passed this and to add some flash to the app, I want to animate a style of screen change. For instance, when a finger is dragged left, push the current view to the side and bring the next it, very similar to how a gallery does it, except I would like it to be able to scroll vertical as well. Any help or tutorials will be appreciated ~Aedon.

• ImageMagick installation confusion

  - by Codemonkey

  Well this is turning out to be a pain. I'm on CentOS 6.5. I saw on the PECL ImageMagick changelog that they added a load of constants for new filters, such as LANCZOS2SHARP. Some testing I did earlier suggested that PhotoShop 6.5 was able to downsize photos with better clarity than my current ImageMagick's best effort of LANCZOS, so I thought I'd try to upgrade to test out the newer filters. So, first port of call - get source from pecl for 3.2.0RC1. Installed with no problems. But, ah-ha. Although it says it only requires IM 6.2.4, the filters I'm after don't work unless you have 6.6.6+ So I go http://www.imagemagick.org/script/install-source.php to install the newest version. This is the bit that's puzzled me. It all appears to have installed fined. The tests work fine, passing 40 out of 40. If I run identify -version on the command line it outputs 6.8.9 But if I echo Imagick::getVersion() in PHP it shows 6.5.4, even after restarting php-fpm. rpm -qa | grep ImageMagick shows that I still have 6.5.4 installed locate ImageMagic also only seems to show the 6.5.4 one I feel that the missing link here is ImageMagick-devel, do I need to install that too? How do I go about doing that? Or do I just need to reinstall the pecl-imagemagick 3.2.0RC1 now that I have the latest IM installed?

• How do game trainers change a address in memory thats dynamic?

  - by GameTrainersWTF

  Lets assume i am a game and i have a global int* that contains my health. A game trainers job is to modify this value to whatever in order to achieve god mode. I've looked up tutorials on game trainers to understand how they work, and the general idea is to use a memory scanner to try and find the address of a certain value. Then modify this address by injecting a dll or whatever. But i made a simple program with a global int* and its address changes every time i run the app, so i don't get how game trainers can hard code these addresses? Or is my example wrong? What am i missing?

• Best Solution For Authentication in Ruby on Rails

  - by Dan Wolchonok

  I'm looking for a pre-built solution I can use in my RoR application. I'm ideally looking for something similar to the ASP.NET Forms authentication that provides email validation, sign-up controls, and allows users to reset their passwords. Oh yeah, and easily allows me to pull the user that is currently logged into the application. I've started to look into the already written pieces, but I've found it to be really confusing. I've looked at LoginGenerator, RestfulAuthentication, SaltedLoginGenerator, but there doesn't seem to be one place that has great tutorials or provide a comparison of them. If there's a site I just haven't discovered yet, or if there is a de-facto standard that most people use, I'd appreciate the helping hand.

• Need generated UML diagrams for C++ plugin modules

  - by archer1742

  I need various UML diagrams (sequence/collaboration, class, package, and system component) from some C++ files. However, these files are plugins in a larger programming framework. I have tried generating UML from Rational Rose 7 (2002 version), but I am not very experienced and I am unsure if RR simply cannot produce the diagram, I am doing something wrong, or the diagrams are not rendering correctly because the source files are plugins instead of standalone programs. I have also tried Star Modeler with little success and there seem to be no tutorials on how to generate these models. Is there a simple, bulletproof way to get UML diagrams for C++ files?

• Mod_rewrite not working properly

  - by James P

  I have this in my .htaccess file... RewriteEngine on RewriteRule ^/invite$ /invite.html It's meant to let a user access this url: http://mysite.com/invite and display the invite.html page. I don't want to redirect the user, but just show them the invite.html page from a better looking URL. When I browse to http://mysite.com/invite though, I get a 404 not found error. Is there anything I'm doing wrong? I've tried looking at tutorials for using mod_rewrite but I seem to be doing what they're telling me too... Thanks!

• How to set ItemsSource?

  - by Mark

  This dialog makes no sense to me And I'm having trouble finding good tutorials on it. Most of the examples aren't detailed enough, or do stuff via code, but I'd like to take advantage of the IDE as much as possible. Whats the difference between ItemsSource and DataContext? I'd like to bind it to just a List for starters. I don't need SQL or databases or anything fancy. Where would I declare my list? In MainWindow.xaml.cs? How do I get it to appear in that dialog?

• CruiseControl.NET, Visual Studio & SubVersion

  - by Ian

  Hi All, I am setting up a Continuous Integration server. I have one issue that doesn't seem to be mentioned in the tutorials. I have a ASP.net Web Application that I need to compile and them publish. My Problem is that I seem to be able to compile the app but when I attempt to use a buildPublisher this copies every thing including .svn files & folders and ms CS files. I am using an MSBuild task to compile my source. I tried setting my MSBuild Output Directory to directory but this didn't seem to have any effect. What am I not understanding? Thanks

• Compiling error with API 10

  - by Suhel De Corser

  I was following the basic tutorials on developers.android.com and came by creating the activity named DisplayMessageActivity. It is a blank activity with all the specifications given as shown in the tutorial. FYI, I am using Min SDK = API 8, Target SDK = API 16, Compile with = API 10 The next thing is that there are two errors: "The method getActionBar() is undefined for the type DisplayMessageActivity "home cannot be resolved or is not a field" I tried changing the API to 14 which called for another problem, it wants the minimum API to be 11. That solves these problems, but the main problem is so many devices still use Gingerbread or maybe FroYo. Can't I write for them? Do I have to go higher? How to write for them?

• Should a service layer return view models for an MVC application?

  - by erg39

  Say you have an ASP.NET MVC project and are using a service layer, such as in this contact manager tutorial on the asp.net site: http://www.asp.net/mvc/tutorials/iteration-4-make-the-application-loosely-coupled-cs If you have viewmodels for your views, is the service layer the appropriate place to provide each viewmodel? For instance, in the service layer code sample there is a method public IEnumerable<Contact> ListContacts() { return _repository.ListContacts(); } If instead you wanted a IEnumerable, should it go in the service layer, or is there somewhere else that is the "correct" place? Perhaps more appropriately, if you have a separate viewmodel for each view associated with ContactController, should ContactManagerService have a separate method to return each viewmodel? If the service layer is not the proper place, where should viewmodel objects be initialized for use by the controller?

• Actionscript / Flex: a question about handleAllEvents() method.

  - by Patrick

  Hi, in Adobe tutorials, they suggest to create a class to handle the events (see below the copy/pasted code, and link to page). I was wondering if I have to handle all events with the function handleAllEvents, using if statements to check if the target is the one I want, and the event is the one I want. i.e. if (event.type=="click") && (event.currentTarget == "myId") Should I have a list of ifs (for each target and each event type ?) thanks // events/MyStaticEventHandler.as package { // Empty package. import flash.events.Event; import mx.controls.Alert; public class MyStaticEventHandler { public function MyStaticEventHandler() { // Empty constructor. } public static function handleAllEvents(event:Event):void { Alert.show("Some event happened."); } } } Link (at the bottom): http://livedocs.adobe.com/flex/3/html/help.html?content=events_05.html

• Delete database. Entity Framework

  - by Idotz

  I have a very annoying issue and I would love a solution. The problem: I followed the MDSN tutorial- http://www.asp.net/mvc/tutorials/mvc-4/getting-started-with-aspnet-mvc4/adding-a-model Then I tried this guide according to my needs and I set up a database GAMES.MDF.   Then, I deleted the database and set it up again, is supposedly work (I can write and read data), but There is no such database in the APP_DATA folder. Like it keeps it somewhere in my PC and reuse it.   I even tried a new project and it did not work, works but not in the library, and it even uses the data I created before. I even deleted the DB from SQL Server Management Studio 2008. Does anyone know what the hell? How do I delete it permanently, not to remain any trace of him?   Thank you.  Ido

• recommend a server side technology for gwt (beginner)

  - by user486503

  hi all ! I am developing a gwt project and am looking for an appropriate server side technology. it should support be open source and support user login (and not using openID...) with password recovery etc it seems that the de-facto standard would be spring + hibernate. however, I am unfamiliar with neither of them and understand that the learning curve (especially for spring) is very high. gwt was quite easy to learn using GOOG's excellent online tutorials but the spring equivalent seem to impose lots of configuration files and deeper understanding of its internals. so I am looking for a simpler server side technology to deploy my gwt app. I am definitely prepared to learn a new framework if necessary but not something that would take me 2 months just to understand the fundamentals... any ideas...?
