[RESOLVED] quick arry question

[kayleigh]

Rather then adding arry(0) for all 10 member sof the arry i was trying to think of a work around.
any thing obviously wrong with this?

    Private Sub arryTextBox(ByVal root As Control)

        For Each ctrl As Control In root.Controls
            For x As Integer = 0 To arry.Count - 1
                arry(x) = CType(ctrl, TextBox).Text
            Next
        Next ctrl

    End Sub

    Private Sub arryTextBox(ByVal root As Control)
        For Each ctrl As Control In root.Controls
            If TypeOf ctrl Is TextBox Then
                For x As Integer = 0 To arry.Count - 1
                    arry(x) = Me.Controls("TextBox" & x.ToString()).Text
                Next
            End If
        Next ctrl
    End Sub

Returns nullreference. But i renamed the first instance of the textbox to 0 to avoid this.

Perhaps, if you told us what exactly you are trying to achieve we could offer you better help.
As for the null reference it's probably due to the fact that your array had not been properly initialized or no control with the name TextBoxN where N is a some number exist.

[kayleigh]

Sorry cicatrix. Lets try to explain better.

20 textbox controls, Need to loop through these to get there values to add to an array.

arry(0) = textbox1.text
arry(1) = textbox2.text

etc just seems a long way to go about it.

[kayleigh]

Very strange, it works now............. Maybe a typo in the textbox

[cicatrix]

Consider using List or Dictionary collections instead of arrays.

[kayleigh]

Do you mean list of string? when you say list....

[cicatrix]

I mean

Dim arry As New List(Of TextBox)

Or

Dim arry As New Dictionary(Of String, TextBox)
