I can use the numbkeys.
with the virtual handle vk_numpad_0-9
but only if NumLook is pressed..
and the 2 4 6 and 8 is possible to press without pressed numlock key..
but i need the other keys too (1,3,7,9) from the numpad.

What about ensuring that the num-lock is switched on? And if it wasn't, turning it off again.
Should I post a code for this?

var switchedOff: boolean;
   procedure Switch;
   begin
   if switchedOff then
      begin
      keybd_event(VK_NUMLOCK, 0, 0, 0);
      keybd_event(VK_NUMLOCK, 0, 2, 0);
      end;
   end;
begin
switchedOff := (GetKeyState(VK_NUMLOCK) <> 1);
Switch;


/// any code
keybd_event(VK_NUMPAD7, 0, 1, 0);
/// any code


Switch;
end;

you can use the vk_ keys for all the function of the numpad, eg.

vk_NumPad0   = $60;
vk_NumPad1   = $61;
vk_NumPad2   = $62;
vk_NumPad3   = $63;
vk_NumPad4   = $64;
vk_NumPad5   = $65;
vk_NumPad6   = $66;
vk_NumPad7   = $67;
vk_NumPad8   = $68;
vk_NumPad9   = $69;

vk_Insert    = $2D;
vk_Delete    = $2E;
vk_Prior     = $21; //3
vk_Next      = $22; //9
vk_End       = $23; //1
vk_Home      = $24; //7
vk_Left      = $25;
vk_Up        = $26;
vk_Right     = $27;
vk_Down      = $28;
vk_NumLock= $90;
