RowInput Method

[Stilgar]

Hi, everybody.
I'm try to reading keyboard through the use of RowInput method (WinXp)
I've trouble with handle entry point (WM_INPUT =$00FF) of my form.
It's never called I've register my form with

Code: [Select]

constructor TForm1.Create(aOwner : TComponent);
var
 Rid:array[0..0] of RAWINPUTDEVICE;
begin
  inherited;   
  // Keyboard
  Rid[0].usUsagePage := 1;
  Rid[0].usUsage := 6;
  Rid[0].dwFlags := 0;
  Rid[0].hwndTarget:=0;

  if not RegisterRawInputDevices(rid,1,SizeOf(RAWINPUTDEVICE)) then
    ShowMessageFmt('RegisterRawInputDevices error=%d',[GetLastOSError]);

Somebody try this way? (I want bypass the latency on reading keyboard repetition key)
Some other way to try?
