KeyPress event behaviour

[claudio]

Hi everybody!

I have a problem with KeyPress event.

I would like to manage the special keys cDownKey and cUpKey but the form react to it only when no one control have the focus.

If i give the focus to a control, the form can't receive the event and the SpecialKeys event is used by the system to navigate on controls. This is ok, but when the focus falls on a TextBox the navigation stops because that events are used to move the caret, so i need to tap on screen to change focus.

There are a way to change this behaviour? On Delphi i remember a property which gives the events to the back form if they are not recognized, there are something similar in b4p or .NET?

I attach a sample

Many thanks
Claudio

Solved!

fgControls library contain the fgGetAsyncKeyState object which intercept all keys sent to the form.

Thanks Filippo!
