Arrays are mechanisms that allow you to treat several items as a single collection. The Microsoft® .NET Common Language Runtime (CLR) supports single-dimensional arrays, multidimensional arrays, and jagged arrays (arrays of arrays). All array types are implicitly derived from System.Array, which itself is derived from System.Object. This means that all arrays are always reference types which are allocated on the managed heap, and your app's variable contains a reference to the array and not the ...

Clearly, this code will list each element in the array, starting at the first element and iterating through to the last element. With just this code, though, with a static array your users will see the exact same output each time they visit this ASP page! Boring. Rather, why not randomly reorder the array so that, when the above snippet of code is used to display the array, the output differs?
Now, before you say, "OK, sure, let's do it," take a moment to step back and think about the cha...

I was surfing the web the other day, looking for Visual Basic questions to answer, when I stumbled across an old FAQ that explained why Visual Basic no longer has arrays with non-zero lower bounds. I don't really buy the explanation given by Paul Vick at (it seems like the needs of the none outweighing the needs of the many to me) but it did start me thinking about arrays....

In this tutorial we will learn how to build simple Dynamic Linked-List that we can insert unlimited objects in it, as well as Removing those objects. Framework Class library provide us with great Data structure like ArrayList, SortedList, Hashtable etc..., but this tutroila focus on building simple Linked-list with some of its functionality to learn us how to uses Self-Referntial Classes & how to build Dynamic lists....

You want to determine if your site has been visited by the IP address 231.34.124.3. How can you quickly figure out if the string "231.34.124.3" is in the array?...

I have often had a need to pass various arrays of data from the server to a browser and vice a versa, and although JavaScript has good array handling facilities what I really wanted was a simple library that implemented array passing in both JavaScript (for the client-side) and VBScript (for the server-side ASP code). Implementing such a library would allow JavaScript code in the client’s browser to send a large amount of data via a single HTTP POST field that the server could then interpret wit...

I have heard many complaints stating that the .NET Framework does not support non-zero based arrays. Much of the noise regarding this issue has been coming from the Visual Basic camp. First, let me say that this is not necessarily true. One of the overloaded CreateInstance methods of the .NET Array object accepts an integer array of dimension lengths, as well as an integer array of lower bounds. The implementation is slightly different than you may be accustomed to, but the effect is the same. I...

While reading through some of Jeff Atwood's old blog entries, I stumbled across this gem: The Danger of Naïveté. In it, Jeff discussed the pitfalls the can befall a programmer who implements a naïve algorithm and calls it a day. Consider an algorithm to randomly reorder an array. If you have a collection of items to reorder, the naïve approach is to enumerate each element and swap its position with an element in some other randomly-selected position. However, such an algorithm (as we discuss in ...

Within any application there eventually is a need to use arrays of data. We find we need the data to hold objects in order to simplify the logic we will be implementing, as well as to make our code more flexible and scalable. Using a class that encompasses an array of objects, which itself holds and array of objects, we find that the topmost class allows us to acquire a simplified means of sorting, filtering, and keeping track of data items, as well as the values of those data items....

If you've used VBScript's arrays before, you're likely aware that you can dynamically resize arrays using the Redim statement. (To learn more, see the technical documentation for Redim.) Sometimes this can be a pain, though. For example, imagine that you wanted to read each line of a text file into an array. Since you do not know the number of lines in the file initially, there is no way to create a preset array size....
