The .NET framework lets you create two types of “empty” arrays: unitialized arrays and arrays that are initialized with zero elements. Uninitialized arrays are actually array variables that are set to Nothing, whereas zero-element arrays are non-Nothing variables that point to arrays with zero elements. Here is the (undocumented) method
By default, when an unhandled exception occurs in a managed application, a dialog box appears that asks you whether you want to debug the application with one of the debuggers that are listed in a listbox. (Notice that Windows Forms applications display a different dialog box.)The behavior of the .NET
The For Each loop always iterates orderly on all the elements of an array or a collection (more precisely, on all the elements of a class that implements the IEnumerable interface). What happens if you need to iterate in reverse order, though? If you have an array or an ArrayList
At times you may need to process elements of an array, a collection, or a dictionary object in random order, for example when sampling a population or (more often) when writing a game, such as a card game. Here’s a class that you can use in a For Each statement
You often need to benchmark a piece of code, which you usually do as follows: Dim start As Date = Now’ insert here the code to benchmarkDim elapsed As TimeSpan = Now.Subtract(start)Console.WriteLine(“Total time: {0} secs.”, elapsed) Thanks to delegates, you can write a reusable routine that can benchmark any Sub
