I'm trying to 'genericize' some code we have spattered around our system.
I want to:
return a generic type,
pass in some kind of delegate containing the method to be called.
I'm pretty new to generics so any help appreciated.
Below is where my finger in the air is(!)

I need to load a Money value in a variable in SSIS using a "Execute SQL Task" component.
I map the return column of a SELECT to a variable.
I've declared the variable "UnknownMoney" as a Double or a Single, but i always receive the error:

Hi all,
I have JSON data being provided to my application but unfortunatly it is not very well formed. Sometimes I am getting String representations of numbers when I am expecting numbers.
For some reason some values may have a prefix of whitespace.
What is the best way to deal with this? Currently I am forced to check the types vi...
I have a project with many calculations involving a lot of real world units :
Distance;
Temperature;
Flow rate;

This project involves complicated and numerous calculation formulas.
That's why I supposed the use of custom types like Temperature, Distance... can be good for code readability. For example:
Temperature x = -55.3;

I just started learning Haskell and I ran into a problem in 2-adic type classes. Here's the important code:
data Rectangle = NoRect | Rect (Float,Float) (Float,Float) | Pane

collides :: s1 -> s2 -> Bool
instance (Collision Rectangle Rectangle) where
collides (Rect (aOrX, aOrY...
i want to create an anonymous type inside a function, when the anonymous type properties are the function parameters.
for example, for the function:
private bool CreatePerson(string FirstName, string LasName, int Age, int height);
i will have an anonymous type with the properties: FirstName,LasName,Age and height.
and the values of the...
Right now, I have:
public <T> T[] toArray(T[] old) {
T[] arr = Arrays.copyOf(old, old.length + size());
int i = old.length;

arr[i] = old.getClass().getComponentType().cast(obj);
++i;
}
return arr;
}
(Note that this does not follow the contract ...
How i can compare type data type in VB.NET?

I'm making a restaurant menu using custom post types for the different menu sections. I used the excellent Custom Post Types UI plugin and the Verve Meta Boxes plugin. I'm then flowing them out into separate loops with several segments of the below code:
<?php

Both MainApp and PluginApp conatin a reference to the IPlugin. Now, in MainApp I scan a plugins folder and search for things that implement the IPlugin interface.
However, it is not working because both MainApp and PluginApp r...
I haven't done much programing in many languages, but I know in C(++), you have to declare a variable type (int,char,etc).
In PHP you, of course, don't have to do that. You can start with $str = "something"; then later $str = array("something" => "smells"); and she is happy.
How does PHP compile? How does it know what the variable typ...
37.807614 to 37.786996
The randomly generated double must have the same precision (num of digits) as those above.
For example, 37.792242 would be good, whereas 37.7823423425 would be bad.

Hi all,
Please bear with me as I am very new to functional programming and Haskell. I am attempting to write a function in Haskell that takes a list of Integers, prints the head of said list, and then returns the tail of the list. The function needs to be of type [Integer] -> [Integer]. To give a bit of context, I am writing an inter...
