VB

Private Sub txt_a_qty_TextChanged(sender As Object, e As EventArgs) Handles txt_a_qty.TextChanged
txt_a_qty.Text = Val(txt_b_qty.Text) - Val(txt_so_qty.Text)
End Sub

this is mean the available quantity equal the buyed quantity minus the sold quantity... what is the right code to not exceed the sold quantity than the available quantity?

What I have tried:

VB

Private Sub txt_a_qty_TextChanged(sender As Object, e As EventArgs) Handles txt_a_qty.TextChanged
txt_a_qty.Text = Val(txt_b_qty.Text) - Val(txt_so_qty.Text)
End Sub

Look at the Math.Min operator:

VB

mostYouCanHave = Math.Min(qtyInStock, qtyOrdered)
