Question

Write a program to carry out the stated task: When one of the buttons is pressed, the face changes to a smiling face [emoticon :-) ] or a frowning face [emoticon :-(]. Written in Visual Basic.

Answer 1

Below is the form:

Name of important controls:

PictureBox: pbImage

Button: btnChange

Below is the Vb code:

Imports System.IO

Public Class Form1

    Private Sub btnChange_Click(sender As Object, e As EventArgs) Handles btnChange.Click
        'Change the image on button click
        If pbImage.Tag = 0 Then
            pbImage.Image = Image.FromFile("frown.png")
            pbImage.Tag = 1
        ElseIf pbImage.Tag = 1 Then
            pbImage.Image = Image.FromFile("smile.png")
            pbImage.Tag = 0
        End If
    End Sub

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        ' set Tag to 0 initially
       pbImage.Tag = 0
    End Sub
End Class

Please note it expects the file name to be 'smile.png' and 'frown.png'. It should be in the folder where the .exe file is. If it is somewhere else, change it in the code accordingly.

Below are the sample outputs:

Upon clicking the "Change" button, it will toggle the image as below:

This completes the requirement. Let me know if you have any questions.
