you will need to modify the constructor of Form2 , so that when it's loaded from Form1 , it can access Form1's Controls.
in Form2 .....
VB Code:
  1. [Color=Blue]Public[/color] [Color=Blue]Class[/color] Form2

  2.     [Color=Blue]Inherits[/color] System.Windows.Forms.Form

  3.  
  4. #[color=blue]Region[/color] " Windows Form Designer generated code "

  47.  
  48. [Color=Blue]#End Region[/color]

  49.  
  50.  [Color=Blue]End Class[/color]
then in Form1 , assuming you have a textbox and a button...
VB Code:
  1. [Color=Blue]Private[/color] [Color=Blue]Sub[/color] Button1_Click([Color=Blue]ByVal[/color] sender [Color=Blue]As[/color] System.Object, [Color=Blue]ByVal[/color] e [Color=Blue]As[/color] System.EventArgs) [Color=Blue]Handles[/color] Button1.Click

  2.         [Color=Blue]If[/color] [Color=Blue]Not[/color] TextBox1.Text = "" [Color=Blue]AndAlso[/color] [Color=Blue]Not[/color] TextBox1.Text = [Color=Blue]Me[/color].Name [Color=Blue]Then

  3. [/color]            [Color=Blue]Dim[/color] frm2 [Color=Blue]As[/color] [Color=Blue]New[/color] Form2([Color=Blue]Me[/color]) [Color=Green]'///[/color] [Color=Green]notice[/color] [Color=Green]the[/color] [Color=Green]Me[/color] [Color=Green]in[/color] [Color=Green]brackets[/color] [Color=Green].[/color] [Color=Green]

  4. [/color]            frm2.Show()

  5.         [Color=Blue]End[/color] [Color=Blue]If

  6. [/color]    [Color=Blue]End[/color]
hope it helps.
