Question

For both questions assume that the three objects on the form were created in the order txtFirst, txtSecond, and lblOne. Determine the output displayed in lblOne when the program is run and the Tab key is pressed. Note: Initially, txtFirst has the focus.

Question1 -

Private Sub txtFirst_Leave(...) Handles txtFirst.Leave
lblOne.BackColor = Color.White
lblOne.Text = "Hello"
End Sub


Question 2 -

Private Sub txtSecond_Enter(...) Handles txtSecond.Enter
lblOne.Visible = False
lblOne.Text = "Hello"
End Sub

Explanation / Answer

As initial focus is on txtFirst
The following code will:
Private Sub txtFirst_Leave(...) Handles txtFirst.Leave
lblOne.BackColor = Color.White
lblOne.Text = "Hello"
End Sub
make lblOne BackColor as White and text "Hello" will be displayed.

On tab key the focus goes on txtSecond and on pressing the enter key:

Private Sub txtSecond_Enter(...) Handles txtSecond.Enter
lblOne.Visible = False
lblOne.Text = "Hello"
End Sub

The label will not be visible because of lblOne.Visible = False
