Browser Button and OpenFileDialog method

Please, how do I

1. Create a Boolean called "fileOpened," and set it to False.

2. Create an instance (object) of IO.Stream called "myStream"

3. Create a "New" OpenFileDialog() instance (object) called "OpenFileDialog1

4. Create two strings called "value" and "fileReader."

Please, kindly write these code for me so that I can create an OpenFileDialog box for a user to search for a text file, open the file, and read the data in to a RichTextBox.

Thank you for assistance.
