    make form transparent while moving and otherwise solid

    Hi

    I am trying to make a form transparent (by reducing the opacity to around 70%) if/when the form is being moved around the screen, but at all other times the form should be solid.

    I have no problem setting the opacity for the form when it moves by doing the following:

    VB Code:
    1. Public Sub moveForm(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Move

    2.    Me.Opacity = 0.7

    3. End Sub

    but the form then stays transparent, how do I set the opacity back to 100% again?

    It's probably something really easy, but I can't work it out.

    Can someone post a link to a list of m.msg ID numbers, or do they appear in the .Net Help files somewhere?
    TIA
