I have built the following DLL...

#include <vcl.h>
#include <windows.h>
#pragma hdrstop

#pragma argsused

#define UM_KEYB (WM_USER+11069)

static HHOOK hkb=NULL;
HWND Handle;

int WINAPI DllEntryPoint(HINSTANCE hinst, unsigned long reason, void* lpReserved)
{
     return 1;
}
//---------------------------------------------------------------------------

__declspec(dllexport) LRESULT CALLBACK KeyboardProc(int nCode,WPARAM wParam,LPARAM lParam)
{
     PostMessage(Handle,UM_KEYB,wParam,lParam);
     return  CallNextHookEx( hkb, nCode, wParam, lParam );
}

__declspec(dllexport) bool installhook(HWND hwnd)
{
     hkb=SetWindowsHookEx(WH_KEYBOARD,(HOOKPROC)KeyboardProc,HInstance,0);
     Handle = hwnd;
     return hkb;
}

__declspec(dllexport) bool UnHook()
{
      return UnhookWindowsHookEx(hkb);
}

and on the App now...

int y=0;
__declspec(dllimport) LRESULT CALLBACK KeyboardProc(int nCode,WPARAM wParam,LPARAM lParam);
__declspec(dllimport) bool installhook(HWND hwnd);
__declspec(dllimport) bool UnHook();

__fastcall TForm1::TForm1(TComponent* Owner)
         : TForm(Owner)
{
     installhook(Handle);
}

void __fastcall TForm1::WndProc(TMessage &Message)
{
         if(Message.Msg==UM_KEYB)
         {
             Caption = y++;
             Message.Result=true;
         }
         else
             TForm::WndProc(Message);
}

void __fastcall TForm1::FormDestroy(TObject *Sender)
{
     UnHook();
}


Why is this not working? What on earth am i doing wrong?
It only captures keystrokes from within my application...
I Want a system-wide hook...
