Hi dia,

function LowOrderBitSet( Value: integer ): boolean;
begin
 Result := (Value and 1 > 0);
end;

function CapsLock : boolean;
begin
 if LowOrderBitSet(GetKeyState(VK_CAPITAL))then Result := True
 else Result := False;
end;

function InsertOn: boolean;
 { Returns the status of the Insert key.    }
begin
 if LowOrderBitSet(GetKeyState(VK_INSERT))then Result := True
  else Result := False;
end;

function NumLock : boolean;
begin
 if LowOrderBitSet(GetKeyState(VK_NUMLOCK))then Result := True
  else Result := False;
end;

function ScrollLock : boolean;
begin
 if LowOrderBitSet(GetKeyState(VK_SCROLL))then Result := True
 else Result := False;
end;

This is a way.

Regards, Zif.
