  • check keyboard state without using KeyboardEvent in AS3

    - by Pieter888
    Is it possible to check for pressed keys without using the KeyboardEvent? I have an ENTER_FRAME event setup called enterFrameHandler and I want to check within the function enterFrameHandler if any keys are pressed. normally when using a KeyboardEvent I could check for keys easily using a switch that checks the KeyCode of the event, but in an ENTER_FRAME event this isn't possible for me. Is there any other way of checking the keyboard's state within the ENTER_FRAME event?

  • What is your favorite pastime to engage in while your project is buidling?

    - by ondesertverge
    As my average project grows in size the sum of build times throughout the day (and night) adds up to a substantial amount of time. Some of the things I or others do in this time include: Reading the news Thinking of ways to advance the project Looking at other projects Throwing darts Checking the unanswered list on stackoverflow.com Build times aren't constant making it hard to plan constructive use of them. I would like to hear of a method in use to make beneficial use of those few minutes that can add up to a few hours.

  • Find maximum positive integer value in Bourne Shell

    - by l0b0
    I'm checking a counter in a loop to determine if it's larger than some maximum, if specified in an optional parameter. Since it's optional, I can either default the maximum to a special value or to the maximum possible integer. The first option would require an extra check at each iteration, so I'd like to instead find out what is the maximum integer that will work with the -gt Bourne Shell operation.

    What is the best editor for Autohotkey with regards to syntax hightlighting, command completion (intellisense), testing etc. I am doing a bit of Autohotkey programming, and being spoiled rotten by Visual Studio, I really miss these features - especially being new to the language/framework.

  • How to detect if a script is being sourced

    - by brianegge
    I have a script where I do not want it to call 'exit' if it's being sourced. Initially I though checking if $0 == bash but this has problems if the script is sourced from another script, or if the user sources it from ksh. Is there a reliable way of detecting if a script is being sourced?

  • Password Validation

    - by Humpton
    Hi there. Using mysql and php Is there any reason / value when checking a password to query the database using the user name and password (after sanitizing, of course) and recording a failed attempt when no rows are returned vs querying the database using the user name and then comparing the return password string? EDIT: To those who mentioned it below, yes the password is hashed up in the database.

  • String format or REGEX.

    - by ThePower
    I need an simple way to check whether a string that is sent to my function is of the form: (x + n)(x + m) //the +'s can be minus' //n and m represent a double //x represents the char 'x' Is there a simple string format that I can use to check that this is the form. As opposed to checking each character singularly. The whitespace will be removed to save any confusion. Regards Lloyd

  • Reverse PInvoke and create a full unmanaged C# program

    - by Fire-Dragon-DoL
    I know this is a strange question but the idea is simple: I prefer C# syntax rather than C++: -Setters and getters directly inside a property -interfaces -foreach statement -possibility to declare an implicit cast operator other small things... What I really don't know is if is possible to import a c++ dll (expecially std libraries) in C# if I don't use any namespace (even System) The idea is just to write a program using everything that you will normally use in C++ (nothing from CLR so), even printf for example Thanks for any answer

  • How do I nested options for plugins in jQuery

    - by Oscar Godson
    I know how to do plugins, but how do I do nested options like: var defaults = { spacing:10, shorten_to:50, from_start:0, from_end:2, classes: { test:'testing' } }; i know that isn't right, i just dont know how to write the proper syntax when I want to do something like this: $('#breadcrumbs').breadcrumbs({classes{test:'new_example'},spacing:12}) other suggestions are welcome, im in need of the ability to custom class names and there are 7, so rather than making something like test_class, example_class, etc id like it cleaner and neater like the example above.

  • dark VS2008, Windows 7 theme, configuration

    - by Aurelius
    So there's plenty of vs.settings files for nice dark syntax highlighting in VS2008, but I find them basically unusable since they're surrounded by an otherwise white visual studio application and general windows environment. I'd like an adequate dark windows 7 theme I can use while coding in VS. All of the 3rd party Win7 themes (that utilize the patched system files) I've come across have had fairly major problems and were unusable for one reason or another. Does anyone out there have a dark theme + VS combination they're actually happy with?

  • Display/hide menu items depending on logged on user

    - by Andrew
    In my web app, I would like to show an "Admin" menu link only to users who have been added to the database as an administrator. What would be the best way to do this in ASP.NET MVC 2? At the moment, I am doing it by checking whether the user exists in the Admin database table for every page. Obviously, there must be a better way to do this. If it helps, I am using Windows Auth.

  • Find location using only distance and bearing?

    - by pinnacler
    Triangulation works by checking your angle to three KNOWN targets. "I know the that's the Lighthouse of Alexandria, it's located here (X,Y) on a map, and it's to my right at 90 degrees." Repeat 2 more times for different targets and angles. Trilateration works by checking your distance from three KNOWN targets. "I know the that's the Lighthouse of Alexandria, it's located here (X,Y) on a map, and I'm 100 meters away from that." Repeat 2 more times for different targets and ranges. But both of those methods rely on knowing WHAT you're looking at. Say you're in a forest and you can't differentiate between trees, but you know where key trees are. These trees have been hand picked as "landmarks." You have a robot moving through that forest slowly. Do you know of any ways to determine location based solely off of angle and range, exploiting geometry between landmarks? Note, you will see other trees as well, so you won't know which trees are key trees. Ignore the fact that a target may be occluded. Our pre-algorithm takes care of that. 1) If this exists, what's it called? I can't find anything. 2) What do you think the odds are of having two identical location 'hits?' I imagine it's fairly rare. 3) If there are two identical location 'hits,' how can I determine my exact location after I move the robot next. (I assume the chances of having 2 occurrences of EXACT angles in a row, after I reposition the robot, would be statistically impossible, barring a forest growing in rows like corn). Would I just calculate the position again and hope for the best? Or would I somehow incorporate my previous position estimate into my next guess? If this exists, I'd like to read about it, and if not, develop it as a side project. I just don't have time to reinvent the wheel right now, nor have the time to implement this from scratch. So if it doesn't exist, I'll have to figure out another way to localize the robot since that's not the aim of this research, if it does, lets hope it's semi-easy.

  • How to extend the Eclipse Java Editor to add coloured overlays

    - by Gavin Clarke
    I have an idea for an Eclipse plugin which I've been toying with. I need to be able to extend the Eclipse Java Editor component and add coloured overlays to the code based on pluggable external metrics. Unfortunately there doesn't appear to be any kind of syntax highlighting extension point. Does anyone know how I might be able to extend the exisitng eclipse Java Editor to add custom highlighting rules? Bear in mind I'm new to Eclipse plugin programming so please give as much detail as possible.
