        System::EventArgs^ e)
    {

        // Cast the sender object back to a ComboBox.
        ComboBox^ ComboBox1 = (ComboBox^) sender;

        // Retrieve the selected item.
        String^ selectedString = (String^) ComboBox1->SelectedItem;

        // Convert it to lowercase.
        selectedString = selectedString->ToLower();

        // Declare the current size.
        float currentSize;

        // If Bigger is selected, get the current size from the 
        // Size property and increase it. Reset the font to the
        //  new size, using the current unit.
        if (selectedString == "bigger")
