我试图在我的应用程序窗口中显示unicode工具提示,但它们似乎没有显示.非unicode文本显示正确,但是一旦我尝试执行unicode,就不会显示工具提示.以下是我目前正在做的事情,感谢任何帮助,谢谢.

     HWND parentHwnd = pickInfo->getViewer().getCachedHwnd();
  CWnd *pWnd = CWnd::FromHandlePermanent(parentHwnd);
  HINSTANCE hInstance = GetModuleHandle(NULL);

  if (isUnicode)
   m_toolInfoW.lpszText = L"This tooltip does not show up at all.";
  else
   m_toolInfoA.lpszText = "Non unicode text";

  if (!m_bTooltipInitialized){
   ::SendMessage(m_tooltipHwnd, WM_DESTROY, 0,0);

   if(isUnicode)
    m_tooltipHwnd = CreateWindowExW(WS_EX_TOPMOST,
     TOOLTIPS_CLASSW, NULL,
     WS_POPUP | TTS_NOPREFIX | TTS_ALWAYSTIP,  
     CW_USEDEFAULT, CW_USEDEFAULT,
     CW_USEDEFAULT, CW_USEDEFAULT,
     parentHwnd, NULL, hInstance, NULL);
   else 
    m_tooltipHwnd = CreateWindowEx(WS_EX_TOPMOST,
     TOOLTIPS_CLASS, NULL,
     WS_POPUP | TTS_NOPREFIX | TTS_ALWAYSTIP,  
     CW_USEDEFAULT, CW_USEDEFAULT,
     CW_USEDEFAULT, CW_USEDEFAULT,
     parentHwnd, NULL, hInstance, NULL);

   if (GetLastError() != 0)
    return;

   ::SetWindowPos(m_tooltipHwnd, …
