SetLayeredWindowAttributes

[NigelShaw]

Hi,

i am in the process of making a form that, by the click of a button, will open a hole to see the underlying window. the SetLayeredWindowAttributes allows this.

Question.

My form is a popup and moves freely.
i click my button to open the hole and it opens
My form stops moving and i cant move it.

Why does the form stop moving and can it be rectified to move with the open hole?

it seems to stem from this-

WS_EX_LAYERED

if comment this out, i dont get the transparent hole and my form moves. If it is uncommented which it needs to so i can apply the new windows style, my form stops moving......


and advice greatly appreciated.



thanks

Nigel
