Slip 2 Q.A) Write a VB.Net program to move the text “Pune University” continuously from Left to Right and Vice Versa. 15 Marks

Answer:

Algorithm / Logic

1. Start the application.
2. Design a Windows Form and place a Label control with the text “Pune University” on it.
3. Add a Timer control to the form and set its Interval property.
4. Initialize a direction variable to control the movement of the label.
5. Start the Timer when the form loads or when a button is clicked.
6. On each Timer tick:
   • Move the label towards the right by increasing its Left property.
   • When the label reaches the right boundary of the form, change the direction.
   • Move the label towards the left by decreasing its Left property.
7. Repeat the process continuously to achieve left-to-right and right-to-left movement.
8. Stop the application.

        Else
            Label1.Left = Label1.Left + 10
        End If
    End Sub
End Class
