Zebra Notes: Open, Save, Save As, and Format with a Rich Text Box

Work with a Rich Text Box; Format Text; Save changes; Remind to Save; Context menues to copy, cut and paste

In this lesson we will create an application similar to notepad, but we will use a RichTextBox so that you can format the text to make it bold, italics, etc.
The file type that we will create is rtf.

In order to do this you will:

• Use variables to track changes;
• Resize a Rich text box;
• Use a timer to show the current time;
• Work with an RTF file;
• Write code to create a context menu
• Implement Ask to Save.
