C# Windows Form

Instructions:

Topics: Open and Save file dialogs, Controls, Designer, Group box, Menu, User input, Events, and Event handlers

Students will create a simple Windows Forms application with a variety of user input controls that can save and load the values in the controls using external files through options in a menu bar.

For this exercise you will implement 3 unique types of user input controls of your choice and a button that can reset all of the user input controls to their default values. All 4 of these controls should be grouped together in a group box container.

You will also add a menu bar with a File option. Under the File option there will be 3 choices: Load, Save, and Exit. Exit should close the application. Save should save the current contents of the user input fields to a file and Load should allow the user to load one of those files. The format to save and load is up to you, but it should not use a third party library.

Use the following guidelines to complete this application:

User Input

• At least 3 unique types of input controls of your choice (TextBox, NumericUpDown, CheckBox, ComboBox, etc.)

• A button that resets all user input controls to their default values

MenuStrip

• Has a top level File option that contains 3 choices: Load, Save, and Exit

Load Data

• Use an OpenFileDialog class to have the user select what file to load.

• Use a StreamReader or any of the other file i/o classes to read in the file and populate the controls with that information.

• Check the documentation of the OpenFileDialog class on the MSDN for examples of how to use it.

Save Data

• Use a SaveFileDialog class to allow the user to select a file to write to.

• Use a StreamWriter or any of the other file i/o writing classes to write the contents of the controls to that file in whatever format you choose.
