Thank you,but get the same error.

[D CODE]

	if(lpszLnkFileDir is null) return;
	HRESULT hr;
	IShellLink pLink;
	IPersistFile ppf;

	hr = CoCreateInstance(CLSID_ShellLink,NULL, 
CLSCTX_INPROC_SERVER,IID_IShellLinkA,pLink);//cast(PVOID*)
	
	DisplayInfoWork("CoCreateInstance ");
	if(FAILED(hr))
	{
		DisplayInfoWork("FAILED(hr) ");
		return ;
	}
	DisplayInfoWork("  pLink is "~pLink.to!string);
	DisplayInfoWork("will QueryInterface hr is "~hr.to!string);
	DisplayInfoWork(IID_IPersistFile.to!string);
	hr = pLink.QueryInterface(IID_IPersistFile, ppf);// err <-
	DisplayInfoWork("pLink.QueryInterface ");

-------------------log info--------------

   pLink is 5E9954
