  • ExtJS GridPanel Scrollbar does not appear in IE7 but it does in Firefox, etc

    - by Snowright
    Setup I have an accordion layout containing a "properties" panel that nests two inner panels. The first inner panel holds a Ext.DataView, while the second panel is the Ext.grid.GridPanel in question. In the screenshot below, the white space containing the folder icon is the dataview, and below that is the gridpanel. Problem In Firefox, Chrome, and Opera, there is a scrollbar that appears when my gridpanel has an overflow of properties. It is only in Internet Explorer that it does not appear. I am, however, able to scroll using my mouse scroll button in all browsers, including IE. I've also tried removing our custom css file in case it was affecting it somehow, but there was no change in doing so. I'm not sure exactly what code I should show as I don't know where the exact problem is coming from but here is the code for the mainpanel and gridpanel. var mainPanel = new Ext.Panel({ id : 'main-property-panel', title : 'Properties', height : 350, autoWidth : true, tbar : [comboPropertyActions], items : [panel1] //panel1 holds the DataView }); var propertiesGrid = new Ext.grid.GridPanel({ stripeRows : true, height : mainPanel.getSize().height-iconDataView.getSize().height-mainPanel.getFrameHeight(), autoWidth : true, store : propertiesStore, cm : propertiesColumnModel }) //Add gridpanel to mainPanel mainPanel.add(propertiesGrid); mainPanel.doLayout(); Any help into the right direction would be greatly appreciated. Thank you.

  • Where do all the old programmers go?

    - by Tony Lambert
    I know some people move over to management and some die... but where do the rest go and why? One reason people change to management is that in some companies the "Programmer" career path is very short - you can get to be a senior programmer within a few years. Leaving no way to get more money but to become a manager. In other companies project managers and programmers are parallel career paths so your project manager can be your junior. Tony

  • Component based game engine design

    - by a_m0d
    I have been looking at game engine design (specifically focused on 2d game engines, but also applicable to 3d games), and am interested in some information on how to go about it. I have heard that many engines are moving to a component based design nowadays rather than the traditional deep-object hierarchy. Do you know of any good links with information on how these sorts of designs are often implemented? I have seen evolve your hierarchy, but I can't really find many more with detailed information (most of them just seem to say "use components rather than a hierarchy" but I have found that it takes a bit of effort to switch my thinking between the two models). Any good links or information on this would be appreciated, and even books, although links and detailed answers here would be preferred.

  • A simple augmented reality application in C#

    - by Ian
    Hi All, I would like to start a personal project that will give me a lot of new concept to learn and understand. After some thought, I figured that an Augmented Reality related project will be the most beneficial for me because of the following reasons: I haven't tried interfacing a program with a live video/camera feed I haven't done any "image processing" project I haven't done any "graphics rendering" ever With that said, you can assume that I will totally suck at AR. So I'm here to ask for some advice regarding the best way to go through this. st milestone project that I am thinking of is to take a cheap webcam and read some Data Matrix using C#. nd milestone project will render some text-overlay on the feed when presented with a certain Data Matrix. rd milestone project will actually render some 3D shapes. I've searched all-around and found some nice yet advanced materials for AR: http://sites.google.com/site/augmentedrealitytestingsite/ http://soldeveloper.com/ http://www.mperfect.net/wpfAugReal/ So I came here to ask the following: Do you think my milestone is reasonable given my "deficiencies"? In order to start Milestone 1, can you give some materials that I can study? I prefer online materials. Thanks!

  • Developing for Mac, without a Mac.

    - by speeder
    Hello I am a "lone wolf" game developer, and games sell more on Mac (because noone make Mac games... bizarre), so I need to make Mac games. My problem is: I don't own a Mac, and I have no way to get one (unless someone donate one to me...), I don't have money even to upgrade my crappy 3 year old PC, or buy a netbook... So, how I develop for Mac without a Mac? I guess that if I installed Mac OS on my machine, it would do, or can I just use Open Darwin instead? Or Mac OS run on virtual machines?

  • How do I create Tetris Blocks in XNA with C#?

    - by Slateboard
    I'm making a Tetris Clone in C# with XNA, and I'm unsure of how to actually implement the blocks. I don't think that making the shapes as images will work (because parts are removed when lines are formed), so I Have blocks to make up the pieces like This. Unfortunately, I don't know how to actually define the blocks to make the pieces, nor do I know how to manipulate them to make them rotate, etc. Edit: I would also need assistance in learning how to make the Tetris Grid too.

  • QtWebKit problems playing HTML5 video

    - by oskar
    I have a simple Qt application that launches a window with a QWebView. I tried several sites using the video tag with h.264, and it either can't play the video at all (as in youtube or sublime video), or it renders the video poorly, with black lines covering parts of it, like when viewing the video here. Is this a known issue with QtWebKit, or have I neglected to do something that would make it work better? My code is below. #include <QtGui/QApplication> #include <QWebView> int main(int argc, char *argv[]) { QApplication a(argc, argv); QWebView *view = new QWebView(); view->load(QUrl("http://webkit.org/blog/140/html5-media-support/")); view->show(); return a.exec(); }

  • How do you protect against specific CSRF attack

    - by Saif Bechan
    I am going trough the OWASP Top 10 list of 2007 and 2010. I stumbled upon Cross Site Request Forgery (CSRF) this is often called session riding as you let the user usee his session to fulfill your wishes. Now a solution to this is adding a token to every url and this token is checked for every link. For example to vote on product x the url would be: 'http://mysite.com?token=HVBKJNKL' This looks like a solid solution to because a hacker can not guess the token. But I was thinking of the following scenario(I do not know if it is possible): You create a website with an hidden iFrame or div. After that you can load my website in it either using just the normal iFrame or ajax. When you have my website loaded hidden inside your website, and the user has a stored session, the following can be done. You can retrieve the token from the URLS, and still do all the actions needed. Is it possible to do something like this. Or is it not possible to do this cross domain.

  • Adding custom options in binded dropdown in asp.net

    - by MarceloRamires
    I have a bound dropdown list populated with a table of names through a select, and databinding. it shoots selectedindexchanged that (through a postback) updates a certain gridview. What happens is, since it runs from changing the index, the one that always comes selected (alexander) can only me chosen if you choose another one, then choose alexander. poor alexander. What I want is to put a blanc option at the beginning (default) and (if possible) a option as second. I can't add this option manually, since the binding wipes whatever was in the dropdown list and puts the content of the datasource.

    As jQuery thickbox is not maintained anymore (as of ThickBox 3.1), what is the best alternative for jQuery thickbox currently available under GPL or similar license.

  • How to fix type names conflicts in Dynamic Data

    - by SDReyes
    Hi Guys! We're working in a Dynamic Data project that will handle entities coming from two different namespaces: myModel.Abby and myModel.Ben. whose classes are: Abby myModel.Abby.Car myModel.Abby.Lollipop Ben myModel.Ben.Car myModel.Ben.Apple So myModel.Abby.Car and myModel.Ben.Car are homonym. when I try to register both ObjectContext's, an exception is thrown telling us that there are type name conflicts between the mentioned classes (although the types belong to different namespaces). How can we overcome type-name conflicts, caused by repeated type names among different namespaces?

  • What is the single best free Eclipse plugin for a Java developer

    - by Bill Michell
    Some Eclipse plugins are mandated by your environment. The appropriate source code management plugin, for example - and I'm not interested in those. Some provide useful enhancements, but in a specific niche. I'm not interested in those. Some are great, but cost money. I'm not interested in those. Some were really useful on older versions of Eclipse, but are now part of the core build of the latest Eclipse version (3.4 as I write this). I'm not interested in those. I want advice on which plugins every Java SE developer should be installing, one per answer please.

  • Deploying xbap in a full trust mode

    - by SituStarz
    I have xbap which needs to run on a full trust mode because my application needs to upload a file from the client machine to process. I have to provide a installation steps to install. If i do it as a click one instillation, do i still get a security error? If so what is the best way to resolve it? If i install it in remote server, I saw couple of options in internet like creating certificates and ask user to import this certificate. Other option is to ask the user to allow access to xbap applications which provides access to all xbap applications (not so good). what is best way? It would be really great, if some could provide me the installation steps for both scenarios.

  • why do game engines prefer static libraries over dynamic link libraries

    - by numerical25
    I've been reading a few gaming books. And they always prefer to create the engine as a static library over dynamic link. I am new to c++ so I am not highly knowledge when it comes to static libraries and dynamic link libraries. All I know is static libraries increase the size of your program, where DLL link libraries are loaded as you need them within your program. [edit] I've played games where it almost seemed they used DLL's to load in sound, lighting, and what not all individually. as the level was loading up. cause you don't necessarily need that when your at the game menu.

  • XNA Class Design with Structs

    - by Nate Bross
    I'm wondering how you'd recommend designin a class, given the fact that XNA Framework uses Struct all over the place? For example, a spite class, which may require a Vector2 and a Rectangle (both defined as Struct) to be accessed outside of the class. The issue come in when you try to write code like this: class Item { public Vetor2 Position {get; set;} public Item() { Position = new Vector2(5,5); } } Item i = new Item(); i.Positon.X = 20; // fails with error 'Cannot modify the return value of Item because it is not a variable.' // you must write code like this var pos = i.Position; pos.X++; i.Position = pos; The second option compiles and works, but it is just butt ugly. Is there a better way?
