I often find myself confused with how the terms 'arguments' and 'parameters' are used. They seem to be used interchangeably in the programming world. What's the correct convention for their use? ...
I was wondering if there is a way (hopefully keyboard shortcut) to create auto generate function headers in visual studio. Example: Private Function Foo(ByVal param1 As String, ByVal param2 As Integer) And it would automagically become something like this...

Hi there, I'm having some trouble with a large spreadsheet of mine. I bring in a lot of raw data into a data sheet, and then do a number of lookups across the data. Using built in functions I've come up with =IF(ISNA(INDEX(Data!$L$7:$L$1100,MATCH(Data!$I$2&$B$199&$B29&Data!$J$5,Data!$K$7:$K$1100&Data!$J$7:$J$1100&Data!$I$7:$I$1100&Data!...
This took me a while to figure out and I found the answer on a foreign-language wiki a number of weeks ago, and it was very helpful, so I thought I would share. ...
Say I have a Python function that returns multiple values in a tuple: def func(): return 1, 2 Is there a nice way to ignore one of the results rather than just assigning to a temporary variable? Say if I was only interested in the first value, is there a better way than this: x, temp = func() ...
A while ago, I asked a question about $, and got useful answers -- in fact, I thought I understood how to use it. It seems I was wrong :( This example shows up in a tutorial: instance Monad [] where xs >>= f = concat . map f $ xs I can't for the life of me see why $ was used there; ghci isn't helping me either, as even tests I do...
I am trying to pass a number to my JavaScript function, but actually a wrong value is getting passed. I am giving the entire code here: <html> <head> <script type="text/javascript"> function test(num) { /*It should alert as 01004 or 1004 but to my surprise it's alerting as 516!*/ alert(num); } </script> </head> <body> <a href="javascrip...
I have a python program, which runs on the CPython implementation, and inside it I must call a function defined in a java program. How can I do this? It would be nice to be able to use some java objects too. Jython is not an option. I must run the python part in CPython. ...
there is a check I need to perform after each subsequent step in a function, so I wanted to define that step as a function within a function. >>> def gs(a,b): ... def ry(): ... if a==b: ... return a ... ... ry() ... ... a += 1 ... ry() ... ... b*=2 ... ry() ... >>> gs(1,2) # should return 2 >>> gs(1,1) # should re...
In AS3 you have a function on a string with this signature: function replace(pattern:*, repl:Object):String The repl:Object can also specify a function. If you specify a function, the string returned by the function is inserted in place of the matching content. Also, is it possible to get the the original string in which I want to re...

I have encountered a problem that I have not come accross yet when setting up a log in page using php.

I have a simple function written in Oracle 9i (version 9.2.0.4.0) to simulate an in-line IF. For those interested, here's the code: create or replace FUNCTION IIF (testExpression NUMBER, trueResult NUMBER, falseResult NUMBER) RETURN NUMBER AS BEGIN /* A simple in-line IF function for use with SQL queries. If the...
ok, embarrassing enough, I posted code that I need explained. Specifically, it first chains absolute value and subtraction together, then tacks on a sort, all the while not having to mention parameters and arguments at all, because of the presense of "adverbs" that can join these functions "verbs" What (non-APL-type) languages support t...
The $args variable should, by definition, contain all arguments passed to a script function. However if I construct a pipeline inside my function, the $args variable evaluates to null. Anyone knows why? See this example: function test { 1..3 | % { echo "args inside pipeline: $args" } ; echo "args outside pipeline: $args" } This is th...
In order to return a value from a VB.NET function one can assign a value to the "Functions Name" or use "return value." I sometimes see these inter-mixed in the same function. Personally, I prefer the return. My question is, what is the internal difference, if any, between the two? ...
I’m trying to figure out how to iterate over an array of subroutine refs. What’s wrong with this syntax? use strict; use warnings; sub yell { print "Ahh!\n"; } sub kick { print "Boot!\n"; } sub scream { print "Eeek!\n"; } my @routines = (\&yell, \&kick, \&scream); foreach my $routine_ref (@routines) { my &routine = &{$routine_ref};...
Im trying to make a simple template system in PHP. I'm new to PHP, so it's nothing serious. I have some problems though: A regular include works: $variable = "test"; include("templates/news.html"); But this won't: This says $variable is undefined: $variable = "test"; getTemplate("news"); The Function: function getTemplate($tpl) ...
