How can I get and set the states of each?

Thanks

Hi Sean!

Sorry, I don't know in Windows, but maybe this helps...

In DOS it was in the BIOS (0040:0018)-READONLY
   bit 7 : Insert
   bit 6 : Caps Lock
   bit 5 : Num Lock
   bit 4 : Scroll Lock
   bit 3 : Control-Num Lock or Pause
   bit 2 : Sys Req (=Alt Sys Req = Print Screen)
   bit 1 : Left Alt
   bit 0 : Right Alt

(also Int 16h/AH=2)
In DOS it was in the BIOS (0040:0017)-WRITE/READ
   bit 7 : Insert
   bit 6 : Caps Lock
   bit 5 : Num Lock
   bit 4 : Scroll Lock
   bit 3 : Alt
   bit 2 : Control
   bit 1 : Left Shift
   bit 0 : Right Shift

(also Int 16h/AH=12h => 2 bytes)

Each time Windows starts I set Caps Lock and Num Lock off with
an own written small assemblerprogram using this address, and
it works!?! Normally it shouldn't, but it works.

Read the post of Alan Lloyd "Get BIOS number",5 may
but I don't find this byte in his text. Maybe he knows it.

Cheers,
Rudy

Hi Sean,
Here is an example:

function IsKeyOn(Key: integer): boolean;
begin
  result:=boolean(GetKeyState(Key) and 1);
end;

Best regards,

Sean, I forgot to tell you about the keys. You need to use the virtual key
codes like VK_CAPITAL for CapsLock for example.
