        ' Add items into ComboBox1
        ComboBox1.Items.Add("Binary")
        ComboBox1.Items.Add("Decimal")
        ComboBox1.Items.Add("Hexadecimal")
        ' Add items into ComboBox1
        ComboBox2.Items.Add("Binary")
        ComboBox2.Items.Add("Decimal")
        ComboBox2.Items.Add("Hexadecimal")
        ' Add Text into ComboBox1
        ComboBox1.Text = "Select Format"
        ' Add Text into ComboBox1
        ComboBox2.Text = "Select Format"
    End Sub

Button1 Click Event

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim Strconvert As String = TextBox1.Text
        Dim Decimals As Integer
        Dim hexadecimal As String
        Dim Binary As String
        Dim x As Integer

        ' convert Binary to Binary
        If ComboBox1.Text = "Binary" And ComboBox2.Text = "Binary" Then
            TextBox2.Text = TextBox1.Text
            ' convert Binary to Decimal
        ElseIf ComboBox1.Text = "Binary" And ComboBox2.Text = "Decimal"
            Decimals = Convert.ToInt32(Strconvert, 2)
            TextBox2.Text = Decimals.ToString
            ' convert Binary to Hexadecimal
        ElseIf ComboBox1.Text = "Binary" And ComboBox2.Text = "Hexadecimal"
            Decimals = Convert.ToInt32(Strconvert, 2)
            hexadecimal = Convert.ToString(Decimals, 16)
            TextBox2.Text = hexadecimal
            ' convert Decimal to Binary
        ElseIf ComboBox1.Text = "Decimal" And ComboBox2.Text = "Binary"
            x = Convert.ToInt32(Strconvert)
            Binary = Convert.ToString(x, 2)
            TextBox2.Text = Binary
            ' convert Decimal to Hexadecimal
        ElseIf ComboBox1.Text = "Decimal" And ComboBox2.Text = "Hexadecimal"
            x = Convert.ToInt32(Strconvert)
            hexadecimal = Convert.ToString(x, 16)
            TextBox2.Text = hexadecimal
            ' convert Hexadecimal to Binary
        ElseIf ComboBox1.Text = "Hexadecimal" And ComboBox2.Text = "Binary"
            Decimals = Convert.ToInt32(Strconvert, 16)
            Binary = Convert.ToString(Decimals, 2)
            TextBox2.Text = Binary
            ' convert Hexadecimal to Decimal
        ElseIf ComboBox1.Text = "Hexadecimal" And ComboBox2.Text = "Decimal"
            Decimals = Convert.ToInt32(Strconvert, 16)
            TextBox2.Text = Decimals.ToString
        Else
            If ComboBox1.Text = "Select Format" Or ComboBox2.Text = "Select Format" Or ComboBox1.Text = "" Or ComboBox2.Text = "" Then
