How to swallow panel activation

[PaoloB]

I am trying to have a TOPMOST panel always NOT ACTIVE also pressing on it and on its controls.
I only need to receive mouse events on this panel leaving it inactive (like the On Screen Keyboard of Windows NT).

I have tryed to return a non-zero value intercepting some WM messages to the window but is not working ?!?

Does anybody knows how can I solve this problem?

Any help would be very appreciated.

Thanks in advance.
