  • Is "for(;;)" faster than "while (TRUE)"? If not, why do people use it?

    - by Chris Cooper
    for (;;) { //Something to be done repeatedly } I have seen this sort of thing used a lot, but I think it is rather strange... Wouldn't it be much clearer to say while (TRUE), or something along those lines? I'm guessing that (as is the reason for many-a-programmer to resort to cryptic code) this is a tiny margin faster? Why, and is it REALLY worth it? If so, why not just define it this way: #DEFINE while(TRUE) for(;;)

  • JQuery Tablesorter clear table information

    - by conversoid
    I've created a jquery table that from time to time needs to be cleared and the re-populated, my clear method is this: //Clear table content before repopulating values $('#tabela_dash2_maquinas .real-content table tr:gt(0)').remove(); Now i'm trying to use tablesorter to sort a specific column, but my problem is that when I enable the tablesorter: //Initialize tablesorter $("table").tablesorter(); The table clearing method is not working anymore, it just keeps adding the new data with the old data, creating a lot of repeated information. Please help

  • Powershell interact with open Excel

    - by HKK
    To interact with excel in Powershell it is common to start a new excel as follows: $x = New-Object -comobject Excel.Application Instead of that I have an open Excel process already. (I get it as follows) $excelprocess = Get-Process | Where-Object {$_.name -eq "excel"} | Sort-Object -Property "Starttime" -descending | Select-Object -First 1 Is there a way to interact with this specific excel process over PS?

  • How to reorder type members with Resharper?

    - by AngryHacker
    Typical scenario: a class that a lot of people have worked on. I'd like to sort methods, properties, etc... in alphabetical order. I'd like to be able to do this within the region or globally in the class. I see the feature in Resharper to do it, but it does not seem to do anything.

  • Accessing Subversion commit data externally

    - by gaoshan88
    I have need to access subversion data (commit messages, files updated, revision numbers, dates modified, author, etc.) externally. Is this something for some sort of subversion hook or is there a decent third party package for this or some other "best practice" way to approach accessing subversion data externally (and by external I mean from a php/ruby or python script... external to subversion itself)?

Is this possible in PHP? If not possible, I am willing to try anything else that can do this! Thanks all

  • order array containing text and numbers

    - by ptrn
    I'm looking for the easiest way to sort an array that consists of numbers and text, and a combination of these. E.g. '123asd' '19asd' '12345asd' 'asd123' 'asd12' turns into '19asd' '123asd' '12345asd' 'asd12' 'asd123' This is going to be used in combination with the solution to another question I've asked here. The sorting function in itself works, what I need is a function that can say that that '19asd' is smaller than '123asd'. I'm writing this in JavaScript.

  • Assigning IDs to instances of a class (Pythonic)

    - by mellort
    I want to have each instance of some class have a unique integer identifier based on the order that I create them, starting with (say) 0. In Java, I could do this with a static class variable. I know I can emulate the same sort of behavior with Python, but what would be the most 'Pythonic' way to do this? Thanks

  • Is there a simple automatic backup system for Visual Studio projects?

    - by Jelly Amma
    Hello, I'm using Visual Studio 2008 Express and I would like Visual Studio (or perhaps an Add-in) to save my whole project to some sort of auto-incrementing archive or whatever would help me recover from disasters. I don't have much need for SVN or complex versioning systems. I'm just looking for something simple and lean. Any help would be much appreciated. Jenny PS : I looked into the built-in AutoRecover feature but it doesn't seem to save more than a few files.

  • Does content always have to be in chronological order in an RSS feed?

    - by Chris Henry
    I run a site where users can upload content that is displayed in a gallery where other users can sort and filter that content. While implementing RSS feeds, I was wondering how common it was for an RSS feed to display items in an order that's different from chronological. For example, displaying content by Most Views first. This could be useful for someone wanting to keep tabs on trending content. How do RSS readers handle this, since most RSS feeds are ordered chronologically?

  • How can I run ARM code from external memory?

    - by samoz
    I am using an LPC2132 ARM chip to develop a program. However, my program has grown larger than the space on the chip. How can I connect my chip to some sort of external memory chip to hold additional executable code? Is this possible? If not, what do people normally do when they run out of chip space?

  • How to make Multi-Pane GUI in WPF or C#?

    - by xarzu
    I have seen this user interface in some screen shots of some RSS Readers. It is a multi-pane user interface. THere are three panels or "panes" to the window, in other words, the window is divided into three parts and the user is able to mouse over the division and click on the seperation bar and resize the section. How is this sort of GUI developed in C#?

  • Why do I get so many errors building my Android project with Ant?

    - by synic
    Now that I sort of know my way around the SDK/API, I've switched from Eclipse back to my favorite text editor, which means I have to use ant to build my project, however: It seems every other time I compile the project, a lot of drawables get corrupted, resources lose their ids (resulting in NPEs in the code), or classes throw "Verify Errors". The only way to fix this is by removing the bin and gen folders, and recompiling, which is obviously annoying. Is there any way to avoid this? btw, I'm using ant 1.7.1, java version "1.6.0_20"

  • Does armcc optimizes non-volatile variables with -O0 ?

    - by Dor
    int* Register = 0x00FF0000; // Address of micro-seconds timer while(*Register != 0); Should I declare *Register as volatile while using armcc compiler and -O0 optimization ? In other words: Does -O0 optimization requires qualifying that sort of variables as volatile ? (which is probably required in -O2 optimization)

  • How do "and" and "or" work when combined in one statement?

    - by orokusaki
    For some reason this function confused me: def protocol(port): return port == "443" and "https://" or "http://" Can somebody explain the order of what's happening behind the scenes to make this work the way it does. I understood it as this until I tried it: Either A) def protocol(port): if port == "443": if bool("https://"): return True elif bool("http://"): return True return False Or B) def protocol(port): if port == "443": return True + "https://" else: return True + "http://" Is this some sort of special case in Python, or am I completely misunderstanding how statements work?

  • How to avoid strange characters before the request in firefox?

    - by murze
    Hi, on a website i'm currently developing I'm using jquery to do all sort of magic things :-) In firefox however, when I load jquery 1.4.2 there are sometimes funny characters in front of the request. You can see the strangers characters in this screenshot (thank you firebug). In safari, Chrome and IE these funny characters don't appear, jquery is loading fine in those browsers. Why are those characters appearing and how can I remove them? Thanks!!
