  • forslash as the default path separator in windows?

    - by Meitham
    Since windows now accept the forslash "/" as a path separator in addition to its default backslash path separator, so that both c:\windows and c:/windows are valid paths (though the later is invalid in cygwin since backslash is escape char) Is there any chance we could set the forslash as the default path separator on windows (GUI), so that the address bar in windows will automatically use it? I heard its possible in a powershell session but anyone knows if it is also possible in a CMD session? Thanks M

  • What are the pitfalls of ADL?

    - by FredOverflow
    Some time ago I read an article that explained several pitfalls of argument dependent lookup, but I cannot find it anymore. It was about gaining access to things that you should not have access to or something like that. So I thought I'd ask here: what are the pitfalls of ADL?

  • Apache .htaccess: ErrorDocument and RewriteEngine not working together

    - by bogdanvursu
    Please take a look at the following .htaccess ErrorDocument 404 /404/ RewriteEngine On RewriteRule (.*) index.php [L] With this setup, I am using header('HTTP/1.1 404 Not Found'); in PHP to redirect to the error handling page and send the appropriate HTTP status code. The correct 404 status code is sent, but the browser shows a blank page and the access log shows "GET /invalid-url/ HTTP/1.1" 404 - Can anyone tell me how to make ErrorDocument work with Apache URL rewrites?

    public class WrapperTest { static { print(10); } static void print(int x) { System.out.println(x); System.exit(0); } } In the above code System.exit(0) is used to stop the program. What argument does that method take? Why do we gave it as 0. Can anyone explain the concept?Thanks.

  • Library for parsing arguments GNU-style?

    - by Delan Azabani
    I've noticed the basic 'style' of most GNU core applications whereby arguments are: --longoption --longoption=value or --longoption value -abcdefg (multiple options) -iuwww-data (option i, u = www-data) They follow the above style. I want to avoid writing an argument parser if there's a library that does this using the above style. Is there one you know of?

  • Delphi Unit local variables - how to make each instance unique?

    - by Justin
    Ok, this, I'm sure is something simple that is easy to do. The problem : I've inherited scary spaghetti code and am slowly trying to better it when new features need adding - generally when a refactor makes adding the new feature neater. I've got a bunch of code I'm packing into a single unit which, in different places in the application, controls the same physical thing in the outside world. The control appears in several places in the application and operates slightly differently in each instance. What I've done is to create a unit with all of the features I need which I can simply drop, as a frame, into each form that requires it. Each form then uses the unit's interface methods to customise the behaviour for each instance. The problem within the problem : In the unit in question (the frame) I have a variable declared in the IMPLEMENTATION section - local to the unit. I also have a procedure, declared in the TYPE section which takes an argument and assigns that argument to the local variable in question - each form passes a unique variable to each instance of the frame/unit. What I want it to do is for each instance of the frame to keep its own version of that variable, different from the others, and use that to define how it operates. What seems to be happening, however, is that all instances are using the same value, even if I explicitly pass each instance a different variable. ie: Unit FlexibleUnit; interface uses //the uses stuff type TFlexibleUnit=class(TFrame) //declarations including procedure makeThisInstanceX(passMeTheVar:integer); private // public // end; implementation uses //the uses var myLocalVar; procedure makeThisInstanceX(passMeTheVar:integer); begin myLocalVar:=passMeTheVar; end; //other procedures using myLocalVar //etc to the end; Now somewhere in another Form I've dropped this Frame onto the Design pane, sometimes two of these frames on one Form, and have it declared in the proper places, etc. Each is unique in that : ThisFlexibleUnit : TFlexibleUnit; ThatFlexibleUnit : TFlexibleUnit; and when I do a: ThisFlexibleUnit.makeThisInstanceX(var1); //want to behave in way "var1" ThatFlexibleUnit.makeThisInstanceX(var2); //want to behave in way "var2" it seems that they both share the same variable "myLocalVar". Am I doing this wrong, in principle? If this is the correct method then it's a matter of debugging what I have (which is too huge to post) but if this is not correct in principle then is there a way to do what I am suggesting? Thanks in advance, Stack Overflow - you guys (and gals!) are legendary.

  • Cannot render javascript from controller

    - by Ermin
    I want to display a modal window with an error message, when the user has entered something invalid in a form, but render another action if everything is ok. However, when I try to display the modal window with render :js => "jQuery.facebox(#{...})" only the actual javascript called is displayed: try { jQuery.facebox(...) } catch (e) { alert('RJS error:\n\n' + e.toString()); alert('jQuery.facebox(\"<div class=\'error\'>Error</div>\")'); throw e }

  • Python meta programming question

    - by orokusaki
    I have a meta class MyClass which adds an attribute to a class based on some of the properties of the class's methods. When I subclass MyClass I want it to still have that attribute, and append to the attribute's value based on the sub-class's methods (ie, sub-classing extends the same attribute that the base's meta creates.). Can this be done via the bases argument passed to __new__(cls, name, bases, dct)?

  • If as assert fails, is there a bug?

    - by RichAmberale
    I've always followed the logic: if assert fails, then there is a bug. Root cause could either be: Assert itself is invalid (bug) There is a programming error (bug) (no other options) I.E. Are there any other conclusions one could come to? Are there cases where an assert would fail and there is no bug?

  • GetRef to capture methods?

    - by Thom Smith
    I've just discovered VBScript's GetRef function, which gets a reference to the function named by its argument. Is there any way to get a reference to a method in this way? I have a hunch that VBScript doesn't offer the sophistication of binding needed to do so, but it would sure be nice.
