  • Accessing the "super of this" in Java

    - by gerdemb
    This is what I'm doing now. Is there a better way to access the super class? public class SearchWidget { private void addWishlistButton() { final SearchWidget thisWidget = this; button.addClickHandler(new ClickHandler() { public void onClick(ClickEvent event) { // A better way to access the super class? // something like "this.super" ...? workWithWidget(thisWidget); } } } } I'm programming with Google Web Toolkit, but I think this is really a generic Java question.

  • ASP.NET Free Online E-books or tutorials

    - by the_drow
    I need to learn programming ASP.NET with C# but I can't find a good online book to do so. Is there an ASP.NET equivalent to Diving into python? All of the books are quite expensive. I already know Java and C++, are there any major differences between them and C#? If so are there materials that cover only the differences and what I should learn?

  • Exception throws: encapsulate them or not?

    - by Simon
    Hi there. Once I read an MSDN article that encouraged the following programming paradigm: public class MyClass { public void Method1() { NewCustomException(); } public void Method2() { NewCustomException(); } void NewCustomException() { throw new CustomException("Exception message"); } } Do you think this paradigm makes sense? Wouldn't it be enough to store the exception message in a static const field and then pass it to the exception's constructor, instead of encapsulating the whole exception throw?

    - by MikeJailrod
    Hi. One of my friends has contacted a company that is looking for good, linux network programmers in C, requiring a good background of the linux kernel and low-level network programming. The starting payment would be $70 per hour - I am still at college and honestly i don't know if that's a good salary for such a work as linux network engineer, so i am asking here if $70/h is good enough or not ? Thanks.

  • How can I learn Android?

    - by Vijay Kansal
    I am a newcomer to Android. I know the C And C++ programming languages, but I do not know Java . I want to learn Android right from basics, but I could not find any relevant link or e-book that can help me. Can I begin to learn Android without knowing Java or should i go to learn Java first? From where should I learn Android which should be easy to grasp and learn for a newcomer like me.

  • Fix buttons at the bottom of the screen.

    - by Wilson
    I am a beginner in Android programming. I want to build a simple application with a main list view in the screen and two buttons at the bottom of the screen. When more items are added to the list view, the list view should scroll without increasing the overall length of the list view.

  • Developers portfolios

    - by Alex
    I'm wondering if you have one, or u know any developer/programmer online portofolio. I know many web developers have one (and in many cases very well designed), but not any C++ developer (for example). On the net there are only some good blogs about some programming language, but in many cases these are extremely poor from a design point of view and i'd say very "nerdy".

  • Where do I find the current C or C++ standard documents?

    - by christoffer
    For many questions, especially for C-related ones, the answer seems to be found in "the standard". However, where do we find that - online? Googling can sometimes feel futile, again especially for the C standards, since they are drowned in the flood of discussions on programming forums ;) To get this started, since these are the ones I am searching for right now, where are there good online resources for: C89 C99 C++03

  • Question with "extern" in C

    - by why
    When programming, I would like to split one large file(which contains main function) to many small files, so there is one common case: functions in small files can modify the var from main file, so i think extern is very useful! for instance: in main.c extern int i = 100; in small.c extern int i; fprintf(stdout, "var from main file: %d\n", i); I just want to know is my understanding right?

  • UIWebView doesn't scroll to the bottom of the webpage loaded/created

    - by tom
    I have a UIWebView inside a normal UIViewController. The content of the UIWebView is programming/dynamically created in my program, and it could be very long (multiple table rows). Somehow, after loading, the page won't scroll more then one and half screen of content when swipe on the screen. Because of that I can only see the beginning few rows of data, but not the many others after them. Why is that?

  • How do I mount a remote Linux folder in Windows through SSH?

    - by Jared
    I'm a blind student currently in a system admin/shell programming class. Although ssh works fine for executing commands like ls, pwd, etc editors do not work well with my screen reader and an ssh session. I was wondering if it is possible to mount a Linux folder over ssh so it appears as a windows drive? This way I could edit any files I needed to with accessible software and not have to constantly use SCP to send files back and fourth.

  • why multipart/x-mixed-replace is needed for Comet?

    - by Morgan Cheng
    I'm reading this article about Comet http://en.wikipedia.org/wiki/Comet_(programming). It mentions that browser should support multipart/x-mixed-replace to make XmlHttpRequest Streaming possible. Why this multipart/x-mixed-replace is necessary? Without this header, HTTP response can still be chunked and sent piece by piece to browser, right?

  • What is the most painful development related mistake you have done and what you have learned?

    - by burak ozdogan
    What is the most painful programming mistake you have done and what lesson you have learn after? I guess mine was making a release to production on the development code which was not tested yet. The lesson-learned: Delete any projects that can trigger a release on the live application from CCTray. I only add them when a release to production is necessary since then. And once I am done, I delete them from my project lists.

  • VB6 code for Reading/Writing Windows Registry values

    - by Clay Nichols
    I'm looking for a good example of reading and writing to the Windows Registry using VB6. Yes, I know there are lots of mediocre examples. I spent an hour googling and testing. Some were incredibly complex, others had only some of the functions, and almost none of it had been vetted in any way (voted on). Since Stack Overflow is intended to the canonical location for answers to programming questions, it seems reasonable to post it here.

  • php error message "Notice: Undefined index: aid"

    - by iaagty
    I'm looking for a complete list of security guidelines for programming and deploying PHP web sites and applications on an Apache (Linux) server. Basically, a "security check list" to run through before finishing a project. I.e., Cross Site Scripting Cross Site Request Forgery Sanitize form data that goes into database Disable register globals and error reporting in custom php.ini Upload files below web root ...(the list goes on) I did some searching on the internet and in this forum, but couldn't find a comprehensive, succinct, and complete list of guidelines. Thanks in advance.

  • Cost of sending XMPP messages via Google App engine

    - by Alfred
    Hopefully this question is allowed over here. It does not really have to do with programming per se but with the costs associated with it. My question is: "How much does sending/receiving XMPP messages cost". I can find all the information about email etc. But I could not find information about costs sending/receiving XMPP messages.
