  • Make OS open directory in Python

    - by Vidar
    I am writing a program in Python, and want to get it to make the OS open the current working directory, making for instance Windows open explorer.exe and navigating to the wanted directory. Any ideas on how to do this? The directory is already given by os.getcwd. Cross platform methods preferred :)

  • C++: How to count all instantiated objects at runtime?

    - by nina
    I have a large framework consisting of many C++ classes. Is there a way using any tools at runtime, to trace all the C++ objects that are being constructed and currently exist? For example, at a certain time t1, perhaps the application has objects A1, A2 and B3, but at time t2, it has A1, A4, C2 and so on? This is a cross platform framework but I'm familiar with working in Linux, Solaris and (possibly) Mac OS X.

  • Javascript - proper getAttributeNode on IE6+

    - by Darrow
    I have a regular input box (no onchange attribute). <input type="text" id="bar" name="bar" /> For some reason, IE6+ does returns [object], while FF and Chrome returns null. if ((elem.getAttributeNode('onchange')) != null) elem.onchange(); I did also try as: if (typeof(elem.onchange) !== 'undefined') elem.onchange(); What would be the proper cross-browser way to check if the element has the attribute? Thanks

  • PHP detecting filesystem encoding

    - by Evert
    Hi guys, I need to save files with non-latin filenames on a filesytem, using PHP. I want to make this work cross-platform. How do I know what encoding I can use to write the file? I understand many modern filesystems are UTF-8 based (is this correct?), but I doubt Windows XP is (for instance). So, is there a robust detection mechanism? Evert

  • Sanitize file_get_contents

    - by Luis
    I want to use file_get_contents to implement a proxy so I can do ajax cross domain requests. Querystring will be used to supply the URL to file_get_contents. Now the problem is people can muck around with the qurystring in order to read local files on the server. I dont wnat this. Can someone get me a function to sinitize the querystring in order only to accept urls and not local files: ie: ?url=http://google.com.au - OK ?url=./passwords.txt - Not OK

  • DataSet size best practices - are there any general rules?

    - by Galwegian
    I'm working on a desktop application that will produce several in-memory datasets as an intermediary before being committed to a database. Obviously I'm going to try to keep the size of these to a minimum, but are there any guidelines on thresholds I shouldn't cross for good functionality on an 'average' machine? Thanks for any help.

  • Why is it safe to use copy & paste in Flash but not in Javascript?

    - by Lenni
    I'm trying to use copy'n paste in one of my web apps and have read a few articles/SO questions about it. Most people say that using Flash is the only option since most browsers don't allow access to the system clipboard because of security concerns. I can understand this but I wonder why it is okay for Flash do this, but not for the browser. Or has it got nothing to do with security and it is simply to complicated to implement this for cross-platform browser vendors?

  • MvvmCross experiences, hindsight, limitations?

    - by Jason Steele
    I am considering using the MvvmCross framework for a cross platform mobile application that will target Android, iPhone and WP7. Does anyone have any experience with this framework they would like to share, and are they aware of any constraints or limitations that it would be useful to be aware of? For example, am I still able to use native page transitions of my choosing? Are there any performance or storage (app size) implications?

  • SVG, animate a line from x1,y1 to x2,y2?

    - by dskvr
    The animate property is very loosely documented. And unfortunately for me, the way the W3 documents SVG is VERY difficult understand and cross reference. Does anybody know if it is possible to animate a line from point A (x1,y1) to point B (x2,y2), and if so, how would this be done? (example code would put a really bright smile on my face)

  • open source custom tooltip (callout) control/code for asp.net

    - by dotnetcoder
    Looking for a custom tooltip (typical yellow baloon callout) on click of an anchor tag. The tooltip should appear and remain in view until the cross button on the tooltip is clicked. Just looking for a tried and tested open source solution. Tried googling this but most of the tooltip [...missing info?...] Ajax control toolkit has the calloutvalidator which seems like a good choice but is tied up to be used for validation tooltips.

  • What is the most popular generic collection data structure library for C?

    - by Tom Dalling
    I'm looking for a C library that provides generic collection data structures such as lists, associative arrays, sets, etc. The library should be stable and well tested. I'm basically looking for something better than the crappy C standard library. What C libraries fit this description? EDIT: I'd prefer that the library was cross-platform, but failing that, anything that works on Mac/Linux.

  • Real-time equalizer for all audio on computer

    - by greye
    Is it possible to capture all the sound from a computer and have it pass through a equalizer before reaching the speakers? How can you program a band pass filter on it? EDIT: I'm trying to get this on Windows (with Python? heh) but if there is a generic, cross-platform approach that would be great.

  • Is it possible to determine whose code (according to `git blame`) was affected by each hunk output by `git diff`?

    - by Ben
    I have a large cross-cutting commit that I would like to split up according to the authors whose code was affected, both to increase the reviewers' familiarity with the code they're reviewing, and to divide the review burden equitably. I realize that the blame may be mixed within a given hunk, in which case it would be nice to either collect multiple reviewers or just choose the most "blameworthy" one (breaking ties arbitrarily is fine).
