How to set opacity of form

[VB Programmer]

I have a form which has an opacity control of type numbericupdown. It's
supposed to control the opacity of frmMain. Here's my code...

Private Sub numOpacity_ValueChanged(ByVal sender As System.Object, ByVal
e As System.EventArgs) Handles numOpacity.ValueChanged
frmMain.Opacity = Me.numOpacity.Value
End Sub

This doesn't seem to work at all. Any suggestions?

Thanks!

'Opacity' expects a value between 0 and 1. Maybe scaling the selected value
to this interval solves the problem.

I am doing it from .1 to 1.0.

Set Decimal places to 1. Set Increment to 0.1 Set Minimum Value to 0.1 and
Maximum value to 1.0. Set Value to 1.
