change:

Me.Controls.Add(btn(i))

for:

GroupBox1.Controls.Add(btn(i))
0

u can also put this into one line

           btn(i).Location = New System.Drawing.Point(200, 30 * i)
            btn(i).Size = New System.Drawing.Size(100, 20)

can be:

          btn(i).SetBounds(200, 3 * i, 100, 20)
0
 
S-TwilleyCommented:
or a different alternative would be:

        Dim btn(2) As Button
        Dim i As Integer
        For i = 0 To 2
            btn(i) = New Button
            btn(i).SetBounds(200, 3 * (i + 1), 100, 20)
            btn(i).Text = "New Button" + (i + 1).ToString
            AddHandler btn(i).Click, AddressOf Me.ClickButton
        Next

        GroupBox1.Controls.AddRange(btn) ' you have to make sure that all elements in the array are filled

What does it mean to be "Always On"?
