Help with small project! visual basic 2005

Hello all, I am currently taking a visual basic class and have found myself really stumped for the first time with a project. If it helps anyone I am using the book Visual Basic 2005, sixth edition by David Schneider.

Here is the project I am having a lot of trouble getting to work.

Section 3.4 #48

48) Write a program that requests a letter, converts it to uppercase, and gives its first position in the sentence "THE QUICK BROWN FOX JUMPS OVER A LAZY DOG." For example, if the user responds by typing "b" into the text box, then the message "B first occurs in position 10." is displayed.

My main question is how do I make the input of one textbook be affected by the action of pushing my action button produce a certain output in another textbook. I have had trouble with the somewhat similar examples in my book and any advice or tips would be greatly appreciated!

Also the teacher also said to use the programming tools "toupper" and "indexof".

Any help would be greatly appreciated!:)

If you are in fact using VB 2005 then that's a version of VB.Net so I've moved this thread for you.

vb Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim str As String = "THE QUICK BROWN FOX JUMPS OVER A LAZY DOG."
    TextBox2.Text = TextBox1.Text.ToUpper & " first occurs in position " & str.IndexOf(TextBox1.Text.ToUpper).ToString
End Sub
