Probably it?

$R = DllStructCreate("uint")
  $HeapAlloc = DllStructSetData($R,1,DllCall("Kernel32.dll", "ptr", "HeapAlloc", _ 
                                               "hwnd", $GetProcessHeap[0], _ 
                                               "dword", 0x00000004, _ 
                                               "long", $PFNArraySize))
  MsgBox(48,"Error 3","Error: "&@error&" | "&"Handle Heap Alloc: "&DllStructGetData($R,1))
