I am making a resturant menu in visual basic/studio 2012.
I am supposed to make the groups be visible and invisible if their checkboxes are checked or not.

Also I cannot make it compute anything except the first group.

This is the code I have made so far and the two errors I get:

Public Class frmMenu
Private Sub chkBurgers_CheckedChanged(sender As Object, e As EventArgs)
Handles chkBurgers.CheckedChanged

If chkBurgers.Checked Then
grpBurgers.Visible = True
Else
grpBurgers.Visible = False
End If
End Sub
Private Sub chkFries_CheckedChanged(sender As Object, e As EventArgs) Handles chkFries.CheckedChanged

If chkFries.Checked Then
grpFries.Visible = True
Else
grpFries.Visible = False
End If
End Sub
Private Sub chkDrinks_CheckedChanged(sender As Object, e As EventArgs) Handles chkDrinks.CheckedChanged

If chkDrinks.Checked Then
grpDrinks.Visible = True
Else
grpDrinks.Visible = False
End If
End Sub


Private Sub btnCompute_Click(sender As Object, e As EventArgs) Handles btnCompute.Click
Dim sum As Double

If chkBurgers.Checked Then
If radRegular.Checked Then
sum += 4.19
ElseIf radCheese.Checked Or radBacon.Checked Then
sum += 4.79
ElseIf radBaconandCheese.Checked Then
sum += 5.39
End If
End If

If chkFries.Checked Then
If radSmall.Checked Then
sum += 2.39
ElseIf radMedium.Checked Then
sum += 3.09
ElseIf radLarge.Checked Then
sum += 4.99
End If
End If

If chkDrinks Then
If radSoda.Checked Then
sum += 1.69
ElseIf radBottledWater Then
sum += 1.49
End If
End If
txtCost.Text = sum.ToString("C")
End Sub

End Class

Also I recieved two errors which are:
1 Value of type 'System.Windows.Forms.CheckBox' cannot be converted to 'Boolean'. C:\Vis2012\Resturant Menu\Resturant Menu\frmMenu.vb Resturant Menu

2 Value of type 'System.Windows.Forms.RadioButton' cannot be converted to 'Boolean'. C:\Vis2012\Resturant Menu\Resturant Menu\frmMenu.vb Resturant Menu

Given the following code, what are the first four lines displayed in the text box when the code is executed?

Dim arrSales(11, 2) As Double
Dim i As Integer
Dim j As Integer
Dim strLine As String
Dim strDisplay As String

strDisplay = "Output is ..." + vbCrLf
For i = 0 To 11
For j = 0 To 2
arrSales(i, j) = i + j
strLine = vbTab + arrSales(i, j).ToString()
strDisplay += strLine
Next
strDisplay += vbCrLf
Next
TextBox1.Text = strDisplay
