Here is one way to do it.

    Private Sub btnadd_Click(ByVal sender As System.Object, _
        ByVal e As System.EventArgs) Handles btnadd.Click

        Dim firstNum As Single
        Dim secondNum As Single
        Dim total As Single

        firstNum = CSng(txtfirstnum.Text.ToString)
        secondNum = CSng(txtsecondnum.Text.ToString)
        total = firstNum + secondNum
        txttotal.Text = Format(total, "###,###,##0.00")

    End Sub

Go to this web site to read upp on the Format Function

txttotal.Text = Format(total, "###,###,##0.00")
The Format function takes as its first parameter any valid expression, and formats it to a string according to the second parameter which is a string format required.  Look at the web site I posted in the first question and at the bottom of the page under “See Also” you will find links to other pages explaining how to form the format sting.
