Hi,

I am in dispair. I have tried to use the GetKeyboardState function but it gives
me the error 'Actual parameter not matching formal var parameter. Here is a fragment of my code:


var
KeybStateBuf:TByteArray;
pKeybStateBuf:PByte;


begin

pKeybStateBuf:=addr(KeybStateBuf);
                 
GetKeyboardState(pKeybStateBuf);

end.

This doesn't work and I don't know why. Could anybody give me a solution for that terrific problem, please !!

                  Thanks a lot.

                  Oli

This applies to D2. Borland have defined

type
  PKeyboardState = ^TKeyboardState;
  TKeyboardState = array[0..255] of Byte;

for you, so you just need:

var
   KeybStateBuf:TKeyboardState;
begin
   GetKeyboardState(KeybStateBuf);
