onkeypress and onkeydown

[hayate]

Hi,
Sorry for asking a stupid question.But I'm really confused.

In OnkeyPress, this code works properly.
if Key = #13 then Key := #0;

But these code in OnKeyDown don't work. Why?
if Key = Ord('a') then Key := 0;
if Key = VK_ENTER then Key := 0;

Of course KeyPreview = True.

Thanks in advance.

These events are in response to the windows messages WM_KEYDOWN and WM_CHAR. Stopping the KeyDown will not stop the KeyPress.

The choice of which one to stop comes down to what behavior you are trying to stop. In other words, the code you are trying to avoid is on some control's KeyDown or KeyPress; you just have to ':= #0' on the correct one.

Cheers
