Dutch's VB Library - Arrays
An array is a variable that contains a finite number of elements that have a common name and data type. Each element of an array is identified by a unique index number. Changes made to one element of an array do not affect the other elements. A collection is a way of grouping a set of related items. Collections are used in Visual Basic to keep track of many things, such as the loaded forms in your program (the Forms collection), or all the controls on a form (the Controls collection). The following samples projects deal with custom collection and arrays implementation in Visual Basic. Showing: 1 - 20 Zip Description Author Versioin Level Site Date This class enables use the Implements keyword to create real object orientated collections. Also has a clear method! It includes a very good expanation of the use of inheritance and polymorphism in VB6. Rating: Andrew Davey VB 6.0 Intermediate n/a 2000 The DrawEdge function is a useful function provided by the Win32 API. It can draw a variety of the edge styles used to draw buttons, frames and borders around controls and forms. Leo Shuster VB 6.0 Intermediate n/a 1999 Search,  delete, and Add  elements from a dynamic array. Set one array to equal another array. Ethan VB 5.0 Intermediate n/a 1999 This class module is a good example of a user-defined collection class. It provides a number of enhancements to the VB collection, such as the option to not require unique keys, and the ability to change the keys. Psycho VB 6.0 Intermediate n/a 2000 This is a dynamic array class (implemented for Strings but can be easily generalized for any other type of object) based on VB's existing implementation of arrays. It contains all the functionality of a Collection class (plus more) but none of the overhead. Rating: Leo Shuster VB 6.0 Advanced n/a 2001 Generic string sort routines. I prefer to use the 'non-pure' Quick Sort unless you have a good reason to choose another routine. Phil Fresle VB 6.0 Intermediate Home 2000 This project contains code that opens a text file, summarizes the data and demonstrates the bubble or shell sort methods to sort the data array. Rating: Ethan VB 6.0 Advanced n/a 2000 This code makes 2 tables out of ar rays, and uses the Array Tables to save the users User Name and Password. Good beginner's demonstration of the use of multi-dimensional arrays for those who have never used them. Alwee VB 6.0 Beginner n/a 2000 Changes a dynamic array at run-time can be either 1 dimensional or 2 dimensional. When the array is defined tells the user the size of the array that has been made! Absi VB 6.0 Beginner n/a 2000 This code will show some basics such as use the select case feature for manipulating arrays, how to manipulate common controls such as lines and shapes to create dynamic controls such as a "cool button" (without OCX) and creating a rounded frame. Eric Sullivan VB 6.0 Beginner Home 1999 Cad in vb! Demonstrates Arrays and basic i/o features. Jeff Katz VB 6.0 Intermediate Home 1999   Awsome Collection object. It adds many useful functions. Jeff Cameron VB 6.0 Intermediate n/a 2000 This program will show new users of Visual Basic how to create hotspots and custom buttons using the image control. See how variable arrays can be used to switch graphics on a single image control. See how you can use control arrays with different graphics. Rating: Alex Hogan VB 6.0 Intermediate Home 2000 This function parses through HTML code and returns an array filled with the tags and their values. CrowN VB 6.0 Intermediate n/a 2000 This loads a HTML file, checks for links and then returns all the URLs in an array. I showed how to use the functions and then load all the URLs to a listbox. Joseph Huntley VB 6.0 Intermediate n/a 1999 Have you ever wanted a collection that would allow you to see if a particular key exists without having to trap an error?  How about  the ability to rename a key without having to first remove the item and then add it back to the collection with the new key?  Maybe being able to get the key for a particular item by passing the index would be nice?  Or, have you ever needed to be able to use case sensitive key names?  What about a collection that starts with an index other than one? Rating: Bryan Stafford VB 6.0 Advanced n/a 2000 How to go about raising events from the child objects in a collection?  This is a question that has been asked many times in the various on-line forums ever since creating collection classes became possible in Visual Basic. Here is the answer. Rating: Bryan Stafford VB 6.0 Advanced n/a 2000 This project demonstrates the use of 'Implements' and OLE callbacks to polymorphically sort any data grouping whether it be an array, file or anything else. The same technique is used to perform a binary search against any sorted list. J.C. VB 6.0 Advanced Home 2000 This is a little utility that will permit us to examine the contents of a hard-disk. In one place we'll have the directories with their respective files and in another place all the files with different names, in order, among other things, to know in how many directories can be found a specific file. Guillermo Som VB 6.0 Intermediate Home 1999 Simple function for generating a random array of long integers. A simple application that uses the function is included.
