Using Classes and Objects in VB Putting the Decisions into the Temperature Class Now we are still making decisions within the user interface about which methods of the temperature class. It would be even better if all that complexity could disappear into the clsTemp class. getTempString End Sub This removes the decision-making process to the temperature class and reduces the calling interface program to just two lines of code.

For example, you might enter an elapsed time in minutes and seconds with or without the colon. 2 Part 1: Object-Oriented Programming in VB 33 34 Part 1: Object-Oriented Programming in VB Since all styles are likely, you'd like a class to parse the legal possibilities and keep the data in a standard format within. 3" are parsed. Figure 3-2. A simple parsing program that uses the Times class The accessor functions for our Times class include the following. setText (tx as String) setSingle (t as Single) getSingle as Single getFormatted as String getSeconds as Single Parsing is quite simple and depends primarily on looking for a colon.

We will not generally create new names for labels, frames, and forms when they are never referred to directly in the code. Even though VB is case insensitive, we otherwise will begin class names with capital letters and instances of classes with lowercase letters. We will also spell instances and classes with a mixture of lowercase and capital letters to make their purpose clearer. NET By James W. Cooper Table of Contents Chapter 3. Using Classes and Objects in VB Summary In this chapter, we've introduced VB classes and shown how they can contain public and private methods and can contain data.
