Hi All,

I havn't been able to find any other examples like this when it comes to
casting.  Anyway, here goes.  I'm writing a WH_DEBUG hook and below is my
callback procedure.

The lParam points to the address of a DEBUGHOOKINFO structure.  How do I get
the 'data' from this structure and pass it onto the CallNextHookEx function?
Thanks.

LRESULT CALLBACK MyDebugHook(int Code,
  WPARAM wParam, LPARAM lParam)
{
  // if (HDebugHook is 0 it means that a new
  // process has attached to the hook DLL.
  // We must load the HDebugHook value from
  // the temp file so that we can pass it
  // in CallNextHookEx.
  if (HDebugHook == 0) {
    FS = new TFileStream(
      TempHookFile, fmOpenRead);
    FS->Read(HDebugHook, sizeof(HDebugHook));
    delete FS;
  }

  DEBUGHOOKINFO *hookInfo = reinterpret_cast<DEBUGHOOKINFO *>(lParam);
  if(Code == HC_ACTION)
    return CallNextHookEx(HDebugHook, hookInfo->code,
                                          hookInfo->wParam,
hookInfo->lParam);

  if(wParam == WH_SHELL)
    ShowMessage("About to call a Shell HOOK");

// Call the next hook in the chain.
  return CallNextHookEx(HDebugHook, hookInfo->code,
                                        hookInfo->wParam, hookInfo->lParam);

}

Thanks,
