This is an introduction to an approach of creating a multiple-choice question application

This version combines single and multiple choice questions.

This application uses three synchronized numeric up down controls to calculate the percentage of money allocated to each of three institutions.

This example illustrates two things: how to use your own structure in a program and how to use a managed array of a structure (or a class) as a member variable of another structure or class.

A simple example of calculating and displaying the price of an item

This example uses three track bars. When the user slides one of the track bars, the panel display an RGB color that is a combination of the value of each track bar.

Displays the time using (horizontal) progress bars

With this application, you can find out how long a computer has been On or for how long an application has been running

In this example, we use radio buttons to perform simple operations such as addition, subtraction, multiplication, and division

This example draws a series of rectangles to produce a column chart. Then, it uses a SolidBrush value to fill the rectangles.

This is another example of drawing a column chart. The chart is doubled so the values of each category can be visually compared.

This example calculates the amount of overtime worked by an employee of a company in a payroll simulation

This is an application that studies the characteristics of the Button control. It simulates processing orders for a dry cleaning store.

The compound interest is a technique of calculating money owed on a loan depending on the frequency of calculating it.

This application creates a format for the HTML's body tag

An example of processing order for a pizza business

This application calculates the price of an order based on the quantity ordered.

This exercise is meant to apply the theories reviewed in file processing. It simulates taking the grades of a student and saving them to a file and being able to open them.

This example applies the concepts of file processing to create a file-based database meant to create an inventory and process orders for a department store. 

This application applies the concepts reviewed for the DataSet class, the data tables, and the columns. To do this, it simulates a musical instrument store that sells items and saves them as XML.

This is an application used to create an inventory and process orders for an auto parts store. The inventory and the orders are saved in XML files.

In this exercise, we create an application that can be used by a car repair business. An employee creates a work order that includes the parts used to fix the car and the types of jobs performed. When the repair is complete, the user can save it to an XML file.

Saving a a record or file as an XML file
