# Help with coding an application that will calculate the square and square root

How do I go about coding the 'Calculate button' so that when a user is prompted to input a number into a Input box it will will calculate the square and square root of it?

This is what I have so far. I'm pretty sure about the first part, but am confused about the square root part.

``````Private Sub cmdCalc_Click()
â€˜calculate square of a number
lblTsquare.Caption=txtNumber^2
â€˜calculate square root of a number
txtNumber.Text = Sqr(txtNumber.Text)
End Sub``````

So it is

``txtNumber.Text = Sqr(txtNumber.Text)``

and not

``lblTroot.Caption=Sqr(txtNumber.Text)``

?

Figured it out :D It's

``````Private Sub cmdSquare_Click()
'calculate square of a number
lblTSquare.Caption = txtNumber ^ 2
'calculate square root of a number
lblTroot.Caption = Sqr(txtNumber.Text)

End Sub``````
