enable and disabled buttons

[4x2y]

if there are lot of more controls on form like text boxes, check boxes then
how to enable and disable the button in the same manner. note that that should not perform one by one. any function.

The best solution for this is creating a control array, by this way you can use

Private Sub Check1_Click(Index As Integer)
    Command1.Enabled = Not (Check1.Item(Index).Value = 0)
End Sub

If you have 100 checkbox, above line is what you need to enable/disable command1 when any value of them changed.
