About queryCommandValue and IOleCommandTarget::QueryStatus   

MSDN says: queryCommandValue is a wrapper for 
IOleCommandTarget::QueryStatus.

    But I can get value by this:

    CComVariant var;
    spDoc2->queryCommandValue(L"FormatBlock",&var);

    And cannot get value by this:

    OLECMD cmds[1];
    cmds[0].cmdID=IDM_BLOCKFMT;
    struct
    {
	OLECMDTEXT	cmdTxt;
	wchar_t		buffer[32];
    }buf={{OLECMDTEXTF_STATUS,0,32}};
    spCmdTgt->QueryStatus(&CGID_MSHTML,1,cmds,&buf.cmdTxt);

    what's wrong with my code?

    thx!
