Question

i have 20 text boxes and 20 my.settings variables

textboxes and my.settings variables have the same names
textbox name: mid0 and it has the value of my.settings.mid0

the text boxes are created in runtime
and i have a save button and that will save the values of the text boxes in my.settings variables

here is the code

Dim Ctl As Control
    Dim MyTextbox As TextBox
    For i As Integer = 0 To 20
        Ctl = tabc.TabPages(6).Controls.Item("mid" & i.ToString)
        If Ctl IsNot Nothing Then
            MyTextbox = CType(Ctl, TextBox)
            My.Settings.("mid" & i.ToString) = MyTextbox.Text 'this line is the problem
        End If
    Next

so how do i loop through the my.settings variables?
which goes form mid0 to mid20

i tried

CallByName(My.Settings, "mid" & i.ToString, CallType.Set) = MyTextbox.Text

but i get an error “Expression is a value and therefore cannot be the target of an assignment.”

Answer 1

change the My.Settings line to

My.Settings("mid" & i.ToString) = MyTextbox.Text 

which really amounts to removing the period 🙂
