A little help needed with textboxes and tabs!

Hi all, very new to Visual Basic and this forum so not sure if this is the right area to post.

I am trying to write a small program to pull some data from a website and display it.... it will do a whole lot more in the future, but at this stage this is far as I have gotten.

Basically my problem is I have now created TAB's with the form and moved all the buttons etc into the tabs and now my code isn't working, keeps coming up with the following error

"Object reference not set to an instance of an object."

I have google'd and pulled my hair out but can't work out how to fix it.

Here is the code I have so far (see below), if u scroll down to the part " Me.Controls.Item("TextBox" & i).Text() = datadisplay" this is where it throws the error.

I have also attached the project in a rar file.

Thx
Matt.

Public Class Form1

    Public Sub New()

        ' This call is required by the Windows Form Designer.
        InitializeComponent()

        ' Add any initialization after the InitializeComponent() call.


    End Sub

    Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim websiteurl

    End Sub

 
End Class

1) Please use CODE TAGS so we can read your mess.

2) Most people never even HEARD of RAR files.

3) You can loop thru a form's controls. Using the .Tag property could help...

Code:

---

    Private Sub Form1_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated

        Dim t As New TextBox
        t = TextBox1
        t.Text = 4
        For Each c In Me.Controls
            If TypeOf (c) Is TextBox Then
                MsgBox(c.ToString)
            End If
        Next c
    End Sub

Welcome to the forums matbor! :wave:

Can you tell us on which line precisely the error occurs ¿

Also, it would be best if you rather zip your project, instead of Rar :)
