The sender is a reference to the object that contains and raises the event; e is an object that derives from System.EventArgs. System.EventArgs contains no specialized functionality. An event that needs to distribute event data should derive an event-specific class from EventArgs with the additional functionality it requires.

The logger library is a part of the standard library, so it comes with Ruby by default. To use it, you only need to place this line near the start of your program: require 'logger'

or the DNS version (sbsexample.local).

In addition to the general considerations in naming data, special considerations come up in the naming of specific kinds of data. This section describes considerations specifically for loop variables, status variables, temporary variables, boolean variables, enumerated types, and named constants.

Of course, it is very important that the producer and consumer of the Tuple have a clear understanding of what is being returned in the Item# properties . With anonymous types, the properties are given actual names based on the source code that defines the anonymous type . With Tuple types, the properties are assigned their Item# names by Microsoft and you cannot change this at all . Unfortunately, these names have no real meaning or significance, so it is up to the producer and consumer to assign meanings to them . This also reduces code readability and maintainability so you should add comments to your code explaining what the producer/consumer understanding is . The compiler can only infer generic types when calling a generic method, not when you are calling a constructor . For this reason, the System namespace also includes a non-generic, static Tuple class containing a bunch of static Create methods which can infer generic types from

volume = volumeIn; adjclose = adjCloseIn; } public TimeSeriesData() { } }

Managers of programming projects aren t always aware that certain programming issues are matters of religion. If you re a manager and you try to require compliance with certain programming practices, you re inviting your programmers ire. Here s a list of religious issues: Programming language Indentation style Placing of braces Choice of IDE Commenting style Efficiency vs. readability trade-offs Choice of methodology for example, scrum vs. extreme programming vs. evolutionary delivery Programming utilities Naming conventions Use of gotos Use of global variables Measurements, especially productivity measures such as lines of code per day

CS0311: The type 'string' cannot be used as type parameter 'T' in the generic type or method 'Program.ConvertIList<T,TBase>(System.Collections. Generic.IList<T>)'. There is no implicit reference conversion from 'string' to 'System.Exception'."

The hard work of the shopping cart admin page is done by the two functions you ve added to the hatshop database: shopping_cart_count_old_carts and shopping_cart_delete_old_carts. They both receive as parameter the number of days that determine when a shopping cart is old, and they use the same logic to calculate the shopping cart elements that are old and should be removed. The age of a shopping cart is given by the age of the most recently added or changed item and is calculated using the GROUP BY SQL clause. The condition that establishes whether a cart should be considered old is the following: WHERE cart_id IN (SELECT cart_id FROM shopping_cart GROUP BY cart_id HAVING ((NOW() - (inDays||' DAYS')::INTERVAL) >= MAX(added_on)));
