Make Code 39 Extended in .NET Explicit Interface Member Implementations

Iterating through arrays is simple and uses the each method. The each method goes through each element of the array and passes it as a parameter to the code block you supply. For example: [1, "test", 2, 3, 4].each { |element| puts element.to_s + "X" }

Semi joins are joins that return rows from one table based on the existence of related rows in the other table. If you return attributes from the left table, the join is called a left semi join. If you return attributes from the right table, it s called a right semi join. You can achieve a semi join in several ways: using inner joins, the EXISTS or IN predicate with subqueries, and the INTERSECT set operation (which I ll demonstrate later in the chapter). Using an inner join, you select attributes from only one of the tables. If that table is in the one side of a one-to-many join, you also apply DISTINCT. For example, the following query returns customers from Spain that made orders:

public sealed class Program { public static void Main() { // Construct a Manager object and pass it to PromoteEmployee. // A Manager IS-A Object: PromoteEmployee runs OK. Manager m = new Manager(); PromoteEmployee(m); // Construct a DateTime object and pass it to PromoteEmployee. // A DateTime is NOT derived from Employee. PromoteEmployee // throws a System.InvalidCastException exception. DateTime newYears = new DateTime(2010, 1, 1); PromoteEmployee(newYears); }

Custom tasks allow you to write .NET code that can be used in your build process. Custom tasks have all the same abilities that the built-in tasks have. Until this chapter we have created only MSBuild project les; in this chapter we will focus primarily on how your tasks can be written to be effectively used with MSBuild.
