In this project it was required to write a small Notepad program and it will introduce a few areas of programming using C# (which are very important in many programs), including: Windows Forms and the Event Handling model GUI (Graphical User Interfaces), Programs which read from files and write to files, using File Input /Output (File I/O).
The Notepad editor that i create should allow me to do the following:d Create a new file and add some text to the file.
The user should be able to open a new file for editing and type several lines of text into it using a textbox. Open an existing text file on your computer. The user should be able to open a file which already exists and the contents of this file should be displayed in a text box on the form. Save a file on your computer. The user should be able to decide where the file is to be saved and save it using a filename and location of their choice. Find a sequence of characters in the text file which you are currently viewing (a "search" facility). If the sequence of characters is found then the user should be informed of this. The user will need to know the line contents of those lines and also the line numbers. The program should also allow you to open a file for viewing, allow you to select another file and display a message indicating if these files are identical (or not). This will form the basis of a file compare program.
