GroupBox1.Visible = True

Private Sub State_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles State.TextChanged
If CustName.Text <> "" And Address.Text <> "" And City.Text <> "" And State.Text <> "" And Zip.Text <> "" Then

Private Sub CalcButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles CalcButton.Click
Qty = Integer.Parse(Quantity.Text)
QtyPrice = Integer.Parse(Price.Text)
SubTotal = Qty * QtyPrice
SubTot.Text = SubTotal.ToString

I'm not a VB coder (ages ago that I did something in VBA)
Based on this piece of code
Code:
Private Sub State_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles State.TextChanged
If CustName.Text <> "" And Address.Text <> "" And City.Text <> "" And State.Text <> "" And Zip.Text <> "" Then
GroupBox1.Visible = True
End If
End Sub
I would make something like
Code:
Private Sub Quantity_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Quantity.TextChanged
Qty = Integer.Parse(Quantity.Text)
If Qty > 0 And Qty <= 5 Then
' update the item price here
Price.Text = "5"
End If
If Qty > 5 And Qty <= 50 Then
' update the item price here
Price.Text = "3"
End If
End Sub
Not the most perfect code but it shows the idea.
Not sure if VB understand '<=' (less than or equal) and also not sure how to use 'else' in VB.
I am trying to create an if statement (this is for Visual Basic).
