  • "...redeclared as different kind of symbol"?

    - by CodeNewb
    #include <stdio.h> #include <math.h> double integrateF(double low, double high) { double low = 0; double high = 20; double delta_x=0; double x, ans; double s = 1/2*exp((-x*x)/2); for(x=low;x<=high;x++) delta_x = x+delta_x; ans = delta_x*s; return ans; } It says that low and high are "redeclared as different type of symbol" and I don't know what that means. Basically, all I'm doing here (READ: trying) is integrating from low (which I set to 0) to high (20) to find the Riemann sum. The for loop looks kinda trippy too...I'm so lost.

  • C# Get/Set Syntax Usage

    - by RoR
    These are declarations for a Person class. protected int ID { get; set; } protected string Title { get; set; } protected string Description { get; set; } protected TimeSpan jobLength { get; set; } How do I go about using the get/set? In main, I instantiate a Person Tom = new Person(); How does Tom.set/get?? I am use to doing C++ style where you just write out the int getAge() and void setAge() functions. But in C# there are shortcuts handling get and set?

  • What is the "x = x || {}" technique in JavaScript - and how does it affect this IIFE?

    - by Micky Hulse
    First, a pseudo code example: ;(function(foo){ foo.init = function(baz) { ... } foo.other = function() { ... } return foo; }(window.FOO = window.FOO || {})); Called like so: FOO.init(); My question: What is the technical name/description of: window.FOO = window.FOO || {}? I understand what the code does... See below for my reason(s) for asking. Reason for asking: I'm calling the passed in global like so: ;(function(foo){ ... foo vs. FOO, anyone else potentially confused? ... }(window.FOO = window.FOO || {})); ... but I just don't like calling that lowercase "foo", considering that the global is called capitalized FOO... It just seems confusing. If I knew the technical name of this technique, I could say: ;(function(technicalname){ ... do something with technicalname, not to be confused with FOO ... }(window.FOO = window.FOO || {})); I've seen a recent (awesome) example where they called it "exports": ;(function(exports){ ... }(window.Lib = window.Lib || {})); I guess I'm just trying to standardize my coding conventions... I'd like to learn what the pros do and how they think (that's why I'm asking here)!

  • Javascript syntax for abbreviating repeated access to same identifier

    - by yongjieli
    Hi all I wanted to ask if there is a formal way of describing the following code, whereby we can access the same object repeatedly without re-typing the object's identifier: myObj.render(1).render(2).print(); I didn't know how to describe it when trying to form a question; I wanted to know whether or not something like this is possible in javascript, I know that I can do it in VB: myObj.render(1) if(foo == 'bar') .render(2) .print(); Thanks!

  • What does @@variable mean in Ruby?

    - by Andrew
    What are Ruby variables preceded with double at signs (@@)? My understanding of a variable preceded with an at sign is that it is an instance variable, like this in PHP: PHP version class Person { public $name; public function setName($name) { $this->name = $name; } public function getName() { return $this->name; } } Ruby equivalent class Person def set_name(name) @name = name end def get_name() @name end end What does the double at sign @@ mean, and how does it differ from a single at sign?

  • Why cant i use the field user in SQL Server 8?

    - by acidzombie24
    Maybe not literally but the query below gets an error near user. If i change it to userZ it works. WHY can i not use that name? Is there a way to specific its a field instead of a keyword? (or whatever it is) create table Post2 ( id INTEGER PRIMARY KEY NOT NULL, title nvarchar(max) NOT NULL, body nvarchar(max) NOT NULL, user integer REFERENCES Post1(id));

  • jQuery extend $.fn and calling method syntax

    - by MBax
    I understand that you call a method like this when you are extending $.fn. ( $ == jQuery ) //$("div").myMethod(); $.fn.extend({ myMethod: function(){...} }); And like this when you extend the jQuery Object: //$.myMethod2(); $.extend({ myMethod2: function(){...} }); But I don't quite understand what the $() is doing here: $().functionName({ something: 'something' }).myMethod(); Does it have to do with the fact the method is being called including the function name? Thanks in advance and hope this makes sense.

  • Regular Expressions Quick Reference

    - by Jan Goyvaerts
    The Regular-Expressions.info website has a new quick reference to regular expressions that lists all of the regex syntax in one single table along with a link to the tutorial section that explains the syntax. The quick reference is ordered by syntax whereas the full reference tables are ordered by feature. There are multiple entries for some of the syntax as different regex flavors may use the same syntax for different features. Use the quick reference if you’ve seen some syntax in somebody else’s regex and you have no idea what feature that syntax is for. Use the full reference tables if you already know the feature you want but forgot which syntax to use. Of course, an even quicker reference is to paste your regex into RegexBuddy, select the application you’re working with, and click on the part of the regex you don’t understand. RegexBuddy then selects the corresponding node in its regex tree which summarizes exactly what the syntax you clicked on does in your regex. If you need more information, press F1 or click the Explain Token button to open the relevant page in the regex tutorial in RegexBuddy’s help file.

  • Django colon syntax in template tags: only in newer versions?

    - by Alan
    I just deployed an application to a new server, and although I'm using virtualenv, I had to install a new environment on the production server, which has a different architecture. Anyway, I received no TemplateSytaxErrors in development, but on the production server, I get: Exception Type: TemplateSyntaxError Exception Value: Caught SyntaxError while rendering: invalid syntax (views.py, line 25) The offending line is: {% url admin:password_change as password_change_url %} Upon removing that line, the TemplateSyntaxError hops to the next line that has a colon in it (and lets other template tags work fine). So my question is this: is there some discrepancy in versions of Python/Django that would allow or disallow the namespacing syntax? The template tags are in django-grappelli (http://code.google.com/p/django-grappelli/), so I'd rather not go through their code and rewrite all the template tags. Development server: 32-bit Debian Python 2.5.5 Django 1.2.1 Production server: 64-bit CentOS Python 2.4.3 Django 1.2.1 Any ideas?

  • How to make msbuild ItemGroup items be separated with a space rather than semi-colon?

    - by mark
    Dear ladies and sirs. Observe the following piece of an msbuild script: <ItemGroup> <R Include="-Microsoft.Design#CA1000" /> <R Include="-Microsoft.Design#CA1002" /> </ItemGroup> I want to convert it to /ruleid:-Microsoft.Design#CA1000 /ruleid:-Microsoft.Design#CA1002 Now, the best I came up with is @(R -> '/ruleid:%(Identity)'), but this only yields /ruleid:-Microsoft.Design#CA1000;/ruleid:-Microsoft.Design#CA1002 Note the semi-colon separating the two rules, instead of a space. This is bad, it is not recognized by the fxcop - I need a space there. Now, this is a simple example, so I could just declare something like this: <PropertyGroup> <R>/ruleid:-Microsoft.Design#CA1000 /ruleid:-Microsoft.Design#CA1002</R </PropertyGroup> But, I do not like this, because in reality I have many rules I wish to disable and listing all of them like this is something I wish to avoid.

  • How can I set IIS Application Pool recycle times without resorting to the ugly syntax of Add-WebConfiguration?

    - by ObligatoryMoniker
    I have been scripting the configuration of our IIS 7.5 instance and through bits and pieces of other peoples scripts I have come up with a syntax that I like: $WebAppPoolUserName = "domain\user" $WebAppPoolPassword = "password" $WebAppPoolNames = @("Test","Test2") ForEach ($WebAppPoolName in $WebAppPoolNames ) { $WebAppPool = New-WebAppPool -Name $WebAppPoolName $WebAppPool.processModel.identityType = "SpecificUser" $WebAppPool.processModel.username = $WebAppPoolUserName $WebAppPool.processModel.password = $WebAppPoolPassword $WebAppPool.managedPipelineMode = "Classic" $WebAppPool.managedRuntimeVersion = "v4.0" $WebAppPool | set-item } I have seen this done a number of different ways that are less terse and I like the way this syntax of setting object properties looks compared to something like what I see on TechNet: Set-ItemProperty 'IIS:\AppPools\DemoPool' -Name recycling.periodicRestart.requests -Value 100000 One thing I haven't been able to figure out though is how to setup recycle schedules using this syntax. This command sets ApplicationPoolDefaults but is ugly: add-webconfiguration system.applicationHost/applicationPools/applicationPoolDefaults/recycling/periodicRestart/schedule -value (New-TimeSpan -h 1 -m 30) I have done this in the past through appcmd using something like the following but I would really like to do all of this through powershell: %appcmd% set apppool "BusinessUserApps" /+recycling.periodicRestart.schedule.[value='01:00:00'] I have tried: $WebAppPool.recycling.periodicRestart.schedule = (New-TimeSpan -h 1 -m 30) This has the odd effect of turning the .schedule property into a timespan until I use $WebAppPool = get-item iis:\AppPools\AppPoolName to refresh the variable. There is also $WebappPool.recycling.periodicRestart.schedule.Collection but there is no add() function on the collection and I haven't found any other way to modify it. Does anyone know of a way I can set scheduled recycle times using syntax consistent with the code I have written above?

  • How do I add color syntax highlighting to GNU emacs?

    - by Alex Reynolds
    I have two versions of emacs available to me on a locked workstation: $ /usr/local/bin/emacs --version GNU Emacs 22.3.1 $ /usr/bin/emacs --version GNU Emacs 21.4.1 In both cases, my terminal type is xterm when I run either version of emacs. When I run the v21 version of emacs, I get syntax coloring for Perl, HTML, and other modes. When I run the v22 version, I do not get syntax coloring. I would like to migrate from the v21 version because the combination of v21 emacs, GNOME Terminal and GNU Screen is eating Ctrl-arrow key chords, which prevents me from moving quickly between words. (OS X Terminal and GNU Screen do not have this issue.) The v22 version allows use of Ctrl-arrow key combinations with GNOME Terminal and GNU Screen. How do I fix the v22 version (or ask my sys admin to fix) so that it once again highlights syntax and allows me to use Ctrl-arrow key combinations?
