You would need a separate textbox for each row returned from the database.

1. You have to learn how to display the data on a textbox control.
We do it by setting the property Text ob object textbox.
For example.

VB

txtName.Text = "John"

2. You have to learn how to retrieve the data from the database.
In your example, you already have a code to retrieve the firstName column from tblContacts table
using OleDBDataReader.
You can change it to

VB

While sdr.Read()

    txtName.Text = sdr.Item("FirstName").ToString

End While

But the txtName will display the FirstName column of the last record only.
Because every iterative, the txtName.Text will be set by the current iterative sdr.Item("FirstName").ToString

Textbox control is not designed to display the collection of value.

I suggest that you learn a fundamental first before you learn to do a database application.
