22. Logical Operators

This tutorial will cover the Logical Operators in Visual Basic .NET. Similar to the conditional operators, logical operators are used to make a decision using words like “And” and “Or”. Logical operators can help you make a decision based on two or more factors.

Code

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If TextBox1.Text = "" Or TextBox2.Text = "" Then
            MessageBox.Show("You didn't fill in the fields!")
        End If

        If TextBox1.Text = "thepassword" And TextBox2.Text = "thesecondpassword" Then
            Form2.Show()
        End If
    End Sub

End Class
