Hi,

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


var
KeyStateBuf:TByteArray;
pKeyStateBuf:PByte;


begin

pKeyStateBuf:=addr(KeyStateBuf);
GetKeyStateBuf(pKeyStateBuf);

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.

This is definition :

function GetKeyState(nVirtKey: Integer): SHORT; stdcall;


so you need to use integer to retrive the virtual key code.
