  • how can I change top-margin the right way if multiple css class assigned?

    - by Radek
    I assigned these classes menu second_menu menu_about_author to ul so the html code looks like <ul class="menu second_menu menu_about_author"> I wanted this ul to have the same properties like menu and second_menu and then I wanted to move the menu_about_author little bit down. I did so by .menu_about_author { margin-top:40px; } but it didn't work any idea why the margin-top:40px; is crossed? the link to the image is [1]: http://img153.imageshack.us/img153/882/58daeef0c3c846e4a8d6321.png

  • Handling right-click within a MenuItem

    - by tylerl
    Is it possible to check for a right-click on a menu item in .NET? It appears that the framework doesn't expose it as an Event, but I've seen other applications (like Chrome and Firefox) which allow you to bring up a right-click context menu for a menu item. Presumably with a little event-loop magic you can do the same thing in .NET, right?

  • As3 help about addEventListener

    - by mydiscogr
    Hi, I've a little problem, I don't really understand if I can use addEventListener more than one time on the same object (and same callback function) if this case can I have a problem of overflow, or simple flex is so smart to not add again in the same stack same function for examples: var t:CServiceObj = _rModel.userGetBoardJoined(); t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk); t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk); t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk); thanks

  • Strange behaviour of keywords within macros in Clojure

    - by mikera
    I'm a little confused by how keyword accesses seem to behave in Clojure when they are evaluated at macro expansion time. The following works as I expect: (def m {:a 1}) (:a m) => 1 However the same keyword access doesn't seem to work within a macro: (def m {:a 1}) (defmacro get-a [x] (:a x)) (get-a m) => nil Any idea what is going on here?

  • How to fetch parameters when using the Apache Commons CLI library

    - by Mridang Agarwalla
    I'm using the Apache Commons CLI to handle command line arguments in Java. I've figured out my way around it to a decent extent but I need a little help. I've declared the a and b options and I'm able to access the value using CommandLine.getOptionValue. Usage: myapp [OPTION] [DIRECTORY] Options: -a Option A -b Option B How do I declare and access the DIRECTORY variable? Thank you.

  • Do Java programs ever crash?

    - by singh
    Hi I am a c++ programmer , I know little bit about java. I know that java programmers do not have to work with memory directly like C++. I also know that most crashes in C++ appliations are due to memory corruptions. So can an application written in Java crash due to a memory related issue? Thanks

  • Agile Whiteboard Software

    - by PaddyC
    Can anyone recommend decent software that could replace a physical whiteboard, as used in Agile development? I've had a look at http://www.brightgreenprojects.com/ but ideally we'd like something we could host ourselves. We use Jira for issue tracking, and are looking at integrating GreenHopper for project management at the moment. The general feeling among users so far seems to be that GreenHopper is a little clunky. Is there a more straight-forward agile whiteboard software tool out there?

  • Wrapper class for HttpGet / Post in Java?

    - by Tim Green
    Hi, Sorry, I'm quite new to Java. I've stumbled across HttpGet and HttpPost which seem to be perfect for my needs, but a little long winded. I have written a rather bad wrapper class, but does anyone know of where to get a better one? Ideally, I'd be able to do String response = fetchContent("http://url/", postdata); where postdata is optional. Thanks!

  • Why are there magic attributes exposed in the Servlet spec?

    - by Brabster
    It's always seemed a little at odds with the principles of Java that the Java Servlet Spec (2.5 version here) includes a set of magic attributes containing info about included resources, namely: javax.servlet.include.request_uri javax.servlet.include.context_path javax.servlet.include.servlet_path javax.servlet.include.path_info javax.servlet.include.query_string It's not even specifically pointed out in the API documentation, only in the spec where it is a must for correct implementation. This approach feels very wrong, an exposed implementation detail that clients will use and depend on. Why is this information exposed in this way?

  • Is there a jQuery widget equal to DOJO's TitlePane?

    - by Bill Caswell
    I like the visual behavior of the DOJO TitlePane widget, but it has too much other bunk for my purpose. http://dojotoolkit.org/reference-guide/dijit/TitlePane.html#dijit-titlepane Is anyone aware of a jQuery widget that provides the same ability to expose and hide content in a stacked manner with the little flippy-arrow, pane highlighting on mouse over, etc? An accordion does not accomplish my goal being able to have multiple panes open at the same time. Thanks in advance.

  • How to draw an CGImage with some alpha transparency?

    - by mystify
    Want to draw an UIImageView which has an CGImage, and the UIImageView has alpha 0.5f. But this CGContextDrawImage function doesnt take an transparency value. So how could I draw an image slightly transparent? To be clear: The image itself is not transparent, but I want it to be "dimmed" a little bit. Just like you would do with an UIImageView and some alpha like 0.5f :-)

  • What things must I know about OpenAL memory management?

    - by mystify
    I am playing sound with OpenAL, and it seems to increase memory footprint dramatically for every little sound I play. It seems that OpenAL never frees memory itself and that playing a Source causes memory footprint to grow. I couldn't find any good resources about OpenAL memory management, but I bet I must do a lot of stuff myself. Maybe someone knows a ressource for that?

  • Real world examples of Rx

    - by theburningmonk
    I've been playing around with the Reactive Extension for a little while now, but mostly limited to handling/composing user driven events within a WPF frontend. It's such a powerful, new way of doing async programming, and I'm curious as to what other people are doing with it, and where do you think it might be able to improve the way we're currently doing things?

  • Java: how to read BufferedReader faster

    - by Cata
    Hello, I want to optimize this code: InputStream is = rp.getEntity().getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader(is)); String text = ""; String aux = ""; while ((aux = reader.readLine()) != null) { text += aux; } The thing is that i don't know how to read the content of the bufferedreader and copy it in a String faster than what I have above. I need to spend as little time as possible. Thank you

  • Why JEE is widely used in complicated projects?

    - by cane
    Hi. Yesterday me and my friend we've had nice conversation about IT and he asked me WHY JEE is so widely used when it comes to build complicated IT systems? From my point of view advantages are easily visible, but he is IT manager with a lot of Micro$oft experience (and little Java exp.), so I would like to hear your voice. And I'll give him a link of course. I don't want new .NET - JAVA war - just - why JEE :) Thanks, orsonek

  • How many registers in custom VM?

    - by DeadMG
    I'm designing a custom VM and am curious about how many registers I should use. Initially, I had 255, but I'm a little concerned about backing 255 pointers (a whole KB) on to the stack or heap every time I call a function, when most of them won't even be used. How many registers should I use?

  • Introduction to midi programming

    So I have a little (musical) keyboard that has USB midi interface.

Ideally I'm looking for a platform-independent api, through Python or something.

  • C# class type - How to determine whether it is a standard .net framework class

    - by HorstWalter
    C# / .net framework What is the most reliable way to determine whether a class (type) is a class provided by the .net framework and not any of my classes or 3rd party library classes. I have tested some approaches The namespace, e.g. starting with "System." The Codebase of the assembly, where the dll is located All this "feels" a little clumsy though it works. Question: What is the easiest and most reliable way to determine this?
