I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This will change the caption on your form via the forms handle and the SetWindowText() API:

    Private Declare Function SetWindowText Lib "user32" Alias "SetWindowTextA" _
        (ByVal hWnd As IntPtr, ByVal lpString As String) As Integer

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim hWnd As IntPtr = Me.Handle
        SetWindowText(hWnd, "Hello World!")
    End Sub
