Object reference not set to an instance of an object.

I am trying to write a .dll to use to pull up a text so I can count each character, word, paragraph, & sentence. When I trie dto use streamreader to open file I get this:
System.NullReferenceException: Object reference not set to an instance of an object

Here is the code that is getting error
Dim stringProcessor As Course.Class1
ofdMain.ShowDialog()
stringProcessor.StringContents = txtRead.[Text]
txtCharacters.[Text] = Microsoft.VisualBasic.CompilerServices.StringType.FromInteger(stringProcessor.Characters)
txtWords.[Text] = Microsoft.VisualBasic.CompilerServices.StringType.FromInteger(stringProcessor.Words)
txtSentences.[Text] = Microsoft.VisualBasic.CompilerServices.StringType.FromInteger(stringProcessor.Sentences)
txtParagraphs.[Text] = Microsoft.VisualBasic.CompilerServices.StringType.FromInteger(stringProcessor.Paragraphs)
Return

Any help w/ this would be appreciated

This error generally means that you forgot to instantiate a new instance of the object.
Which means that you forgot to use the "New" keyword.

The code below will throw an error, because although myTextBox has been declared, it hasn't been instantiated as a new TextBox object.

VB Code:

Dim myTextBox As TextBox
 
myTextBox.Text = "Blah"

This code will work

VB Code:

Dim myTextBox As TextBox
myTextBox = New TextBox
 
or 
 
Dim myTextBox As New TextBox
 
myTextBox.Text = "Blah"
