• How to make some simple GUI controls?

  - by daniels

  I need to make a DirectX or OpenGL app and i will need a custom GUI for that. I think a button, a input text box, a list box (that will need a scroll bar as there will be more items that can fit on the screen) and a slider control will be enough. I know about CeGUI framework but i just don't like it, way too many XML files for my taste. My question is where should i start in learning how to do this custom GUI controls, are there any tutorial available or any material that could get me started? I haven't done a GUI contol myself before.

• Django and a referrer system question

  - by Hellnar

  Hello, I am trying develop a basic referrer system to my Django website, system will be generating a unique url for each users to share with their friends. Once these friends enter this website, system somehow keep the data that "this user is browsing by the reference of X user" and once this invited person decided to register for an account, system will save this information (maybe as an extra Foreign Key of the inviting user in the UserProfile model) Now how can I keep track of the inviting user from the moment entering using the referred link to the point where he/she registers to the site. Would session framework work on this? If not how could this be done ?

• What do the external JSF libraries/frameworks add?

  - by kgrad

  I have seen mention of a bunch of external JSF Libraries such as ICEfaces, Richfaces, etc. However, I am unsure as to what these libraries actually add over just using JSF 2.0. Are they just additional components that are pre-built? I know that PrettyFaces adds URL rewriting, and I Believe that ICEFaces/Richfaces add Ajax enabled components? What are some other major component libraries, what are their benefits / why should people use them? Additionally, what does a framework like SEAM add over using straight JSF2 with EJB? Is MYFaces simply a different implementation of JSF?

• Eclipse ant build gives "Another singleton version selected", how can I stop that?

  - by Fredrik

  We run org.eclipse.ant.core.antRunner to build our plugins and RCP projects. In the build logs we get a ton of messages like: [eclipse.buildScript] Bundle org.eclipse.X: [eclipse.buildScript] Another singleton version selected: org.eclipse.equinox.X_1.0.4.v20081112-1019 The reason is clear; There are two different versions of a particular bundle and it chose the latest. We cannot change the Eclipse installation to remove the older plugins, so what can be done to get rid of these messages? Bonusquestion: What class prints out these messages? One option could be to create our own version where these messages are never shown.

  - by Amit

  I have a strange requirement for my project.. Suppose I have an app say XYZ installed in an android phone and than I receive an email from the mail server which contains a link like http://XYZ.com/?params(i.e. X=1&Y=2&Z=3) now on click of this link I want to open the XYZ app if it is installed in the phone and in the Activity I would like to get these parameters X,Y and Z and if the app is not installed user should be redirected to play store for downloading XYZ app and after installation app takes charge and behaves as if it was already installed (Opening the first activity with those parameters). How can I achieve that ? I have no idea where to start so even the smallest pointer in right direction will be of great help.

• How can I enable auto-updates in a Qt cross-platform app?

  - by FX

  I love applications that are able to update themselves without any effort from the user (think: Sparkle framework for Mac). Is there any code/library I can leverage to do this in a Qt app, without having to worry about the OS details? At least for Windows/Mac/user-owned-linux-binaries. I could integrate Sparkle on the Mac version, code something for the linux case (only for a standalone, user-owned binary; I won't mess with distros packaging, if my program is ever packaged), and find someone to help me on the Windows side, but that's horribly painful. Surely I'm not the only one who wants to provide this to users?

• Structuremap and creating objects with initial state

  - by Simon

  I have an object which needs a dependency injected into it public class FootballLadder { public FootballLadder(IMatchRepository matchRepository, int round) { // set initial state this.matchRepo = matchRepository; this.round = round; } public IEnumerable<LadderEntry> GetLadderEntries() { // calculate the ladder based on matches retrieved from the match repository // return the calculated ladder } private IMatchRepository matchRepo; private int round; } For arguments sake, lets assume that I can't pass the round parameter into the GetLadderEntries call itself. Using StructureMap, how can I inject the dependency on the IMatchRepository and set the initial state? Or is this one of those cases where struggling against the framework is a sign the code should be refactored?

• Java or Groovy CMS

  - by Don

  Hi, I'm considering developing a school information system using the Grails web framework. Before a school can use the system, they will need to setup the following data School data Students Teachers Subjects Classes etc. I'm considering using a CMS in order to get the ability to CRUD these entities "for free". The CMS may also provide other features out-of-the-box that I could use. Ideally the CMS should be implemented in Java or Groovy, does anyone know of something suitable? I looked at the Weceem CMS plugin for Grails, but it's missing some core concepts I need, e.g. the ability to add users to groups. Thanks, Don

• What technology to use for a RIA

  - by user297159

  I have to develop a online business software solution (similar to ERP) for a company to manage the information exchange for internal use and with external partners. It should be online. What technology should I use, I have checked framewroks like: Flex, Silverlight, Google/GWT, sencha (ExtJS), jQuery, DoJo, Telereik, Infrajistics and others similar. But they seam to be very low level programming. May be this is advantage for other projects, where you need more flexibility, but this project is stright forward. I need something more focused on business software (tables, forms, processes) where and eventually more efficient with less coding, or something I can save time. Is force.com an option? But I can not install this on the customer's servers... Do you have any ideas for me for a web based framework focused on business applications?

• How can I launch an application as Administrator after a WiX MSI has completed?

  - by ray dey

  Hi there I want to launch an application with admin rights after I have completed an installation using a WiX based MSI. I can launch the application just fine, on XP but with Windows 7, it's an issue. The application has a manifest embedded in it that says it should run as administrator and I've changed the impersonate attribute in the Custom Action to "no". I can't change the execute attribute to deferred, as this only works before the InstallFinalize action and I need it after the user has clicked Finish in the MSI. This is my Custom Action: <CustomAction Id="LaunchApp" FileKey="App" ExeCommand="[Command Line Args]" Execute="immediate" Impersonate="no" Return="asyncNoWait" /> Any help on this would be appreciated. Thanks

• C#, MEF - Sign trusted plugins for abuse reduction

  - by Marks

  Hi there. I have a program that is extendable by plugins using the Microsoft Extensibility Framework. But i dont want untrusted sources to give out plugins that may be insecure. So i want to sign the plugins (maybe with Visual Studio's built in signing) and check if the plugins are trustworthy at program start. I didn't find a way to check DLL signing from inside C#. And also there is the problem, that I load the plugins with a DirectoryCatalog. There is no way to tell, which plugin is from which file. Anyone knows a way to do this? Thanks for any help, Marks

• Crop & Resize Images in Wordpress

  - by Thomas

  I have gone through several plugins and I can't find a plugin that simply resizes and crops images to a specific size when they get uploaded. This is different from simply resizing one side of the image, I need it to resize the smallest side and then crop the largest side so that the image fits in a specific space. WP already does this by default with thumbnails but I need to do this with full-sized images as well. I was going to use: http://wordpress.org/extend/plugins/scissors/ but it doesn't work with my installation. Can anyone think of another plugin that does this? Is there a simple way to enable this behavior for full size images by modifying wordpress?

• Location of various javax.xml.* packages within the Java 6 SDK.

  - by celestialorb

  Alright, so recently I was using Notepad++ for all of my programming needs, but I've started using Eclipse for larger-scale Java projects now. I decided to pick up an old project of mine which used various classes within the "javax.xml.*" namespaces. When I was compiling and running the program with Notepad++ it worked just fine, however Eclipse can't seem to find these packages. My question is this, since I obviously have the classes somewhere within my current installation of JDK 6 (since I had no problems when using Notepad++), where can I find the location of the .JAR file(s) that include these namespaces/classes so that I can add them to my Eclipse project? Thanks for any help you can give me! Regards, celestialorb Also, if you're curious about the specific packages I'm looking for they are: javax.xml.soap.* javax.xml.transform.* Thanks again!

• Get array of elements from event

  - by Anton

  I have few nested DIV elements. For example: <div id='id1'><div id='id2'>content</div></div> I attach event to DIVs event handler using jQuery: $('div').click(function () { //some code }); There will be two events when user click on content. So there will be two simultaneous events. Is it possible to get inside event handler array of objects (DIVs) what have click event? May be it is possible using other framework but jQuery?

• What is the recommended way to package perl scripts for CPAN (and CorporatePAN)?

  - by szabgab

  Recently I looked at a module on CPAN that comes with a script to be installed which made me wonder. What is the recommended way to include a script in a package that should end up on the public CPAN and if there is any different recommendation for packages that would be released on an in-house CPAN server? The script starts like this: #!/usr/bin/perl eval 'exec /usr/bin/perl -S $0 ${1+"$@"}' if 0; # not running under some shell Two questions Do I understand correctly the eval part is unnecessary? That will be embedded by the CPAN client during installation and it will be very different when installing on Windows. What is the recommended sh-bang line? Would that be #!/usr/bin/env perl instead of the above?

• Finding the right name for an include that is to be executed before HTML output

  - by Pekka

  I am defining naming conventions for a simple plugin framework. For example: index.php - the main plugin file info.php - returns an array with plugin information install.php - self-explanatory can you think of an elegant, short-hand name for a PHP file that contains the code that is to be executed before any HTML is output? Do any examples from other frameworks come to your mind? What I have been thinking of: head.php - misleading, could be mixed up with HTML <head> before_output.php - clumsy, too long init.php - not exactly correct start.php - current favourite

• Extra space while installing .msi

  - by Cristina

  I have extra space in my custom made .msi. The data to be installed has about 600MB and the installer says it needs 1.4 GB.Switching to a different location then the predetermined one (e.g from C:\Program Files\My_App to F:\My_App) shows that it always need approximately 800 MB on the Windows partition, which is in my case the extra space. Any thoughts on why is this happening? Also can this cause an installation error on a 64-bit OS? I've only installed it on a 32-bit OS and everything is fine, but one of my colleagues is having problems installing it on the above mentioned type.

• Ruby on Rails- :symbols, @iVars and "strings" - oh my!

  - by Meltemi

  New to Rails and trying to get my head around when/why to use :symbols, @ivars , "strings" within the framework. I think I understand the differences between them conceptually only one :symbol instance per project one @ivar per instance multiple "strings" - as they are created whenever referenced (?) Feel free to correct me! The main confusion comes from understanding the rules & conventions of what Rails expects - where and WHY? I'm sure there's an "Ah ha!" moment coming but I haven't had it yet...as it seems pretty arbitrary to me (coming from C/Obj-C). -thx

• Shortcut icon for registered file types in visual studio setup project

  - by Zenya

  It is known that when you create a shortcut and place it in the desktop or program menu directory in a VS setup project, you should also set an icon for it. If not, the default icon will be displayed. However it is natural to think that icons to the files of the registered type (such as pdf, txt, doc, etc.), should be taken from the OS after installation. What I want: What I get: How to implement this? PS: Of course, I can get the pdf and txt icons from somewhere, add them to the VS project and set to the shortcuts, but I believe that there should be a better solution.

• Export DB Tables via phpMyAdmin In Non-Alphabetical Order

  - by dosboy

  I have a MySQL database from a Joomla MultiSite installation where it has a set of tables with different prefixes for each Joomla site. When I export the db via phpMyAdmin it creates a SQL file where the tables are created and populated in alphabetical order. The problem is that the tables for the slave sites have dependencies on the tables for the master site, but alphabetically their prefixes are ahead of the master site. So the export works fine but when I try importing I get error after error and have to manually move sections around in the SQL file to make sure that the dependent tables are created/populated first. So, is it possible to export a db via phpMyAdmin with the tables in a specific order?

• How to add .Net3.5 dll into .Net2.0 project?

  - by macias

  I have a dll which is based on .net 3.5 -- it uses internally for example Linq, but the exposed API is straightforward, no fancy stuff. Since C# generics are resolved at compile time I assume that for calling party all it counts is API (all public parts). However when I try to use this dll from net2.0 project I get info, that the dll cannot be referenced because the dll or one of its dependencies requires a later version of .net framework. I can install any .net version I want on target computer (when entire app is installed), but I cannot change .net version for the project itself. So: how to solve this? When adding a C dll to this project I had no such problems, so are C# dlls self-contained or not?
