Creating Transparent Forms

---

A new property of forms that I think is very cool, yet I still can't come up with a reason to use it in a production application, is the Opacity property. This property controls the opaqueness of the form as well as all controls on the form. The default Opacity value of 100% means that the form and its controls are completely opaque (solid), whereas a value of 0% creates a completely transparent form (no real point in that). A value of 50% then, creates a form that is between solid and invisible (see Figure 6.16). I suppose you could write a loop that takes the Opaque property from 100% to 0% to fade out the form. Other than that, I don't know where to take advantage of this technique. But ain't it cool?
