如何从微软office截图中获取targetPath、workingDir信息(例如：Word 2013.lnk)

Question

尝试使用IShellLink COM接口获取.LNK文件的信息。它适用于许多应用程序快捷方式，但对于Microsoft Office应用程序快捷方式，它不能提供正确的信息，例如：

读取ProgramData\Microsoft\Windows\Start Menu\Programs\Microsoft Office 2013\Word 2013.lnk时

GetPath返回"C:\Windows\Installer{90150000-0011-0000-0000-0000000FF1CE}\wordicon.exe“

不是C:\Program Files (x86)\Microsoft Office\Office15\WINWORD.exe

有没有办法从这样的.lnk文件中获取目标信息。双击快捷方式时windows用来启动应用程序的。

下面是我尝试过的C++代码

IShellLinkDataList* comShellLinkDataList;
if (SUCCEEDED(psl->QueryInterface(IID_IShellLinkDataList,(void**)&comShellLinkDataList)))
{
    DWORD flags = 0;
    if (SUCCEEDED(comShellLinkDataList->GetFlags(&flags)))
    {
        if (flags & SLDF_HAS_DARWINID)
        {
            PIDLIST_ABSOLUTE pidList;
            if (SUCCEEDED(psl->GetIDList(&pidList)))
            {
                IShellFolder* shellFolder;
                PCITEMID_CHILD childItem;
                if (SUCCEEDED(SHBindToParent(pidList, IID_IShellFolder, (void**)&shellFolder, &childItem)))
                {
                    STRRET strRet;
                    if (SUCCEEDED(shellFolder->GetDisplayNameOf(childItem, SHGDN_NORMAL | SHGDN_FORPARSING, &strRet)))
                    {
                        TCHAR path[MAX_PATH] = {0};
                        if (SUCCEEDED(StrRetToBuf(&strRet, childItem, path, MAX_PATH)))
                        {
                            return path;
                        }
                    }                                    
                }                                
            }

        }
    }  
}

function GetExeNameFromShellLink(AShellLink: IShellLink): UnicodeString;
var List: IShellLinkDataList;
    Flags: DWORD;

        AShellLink.Resolve(0, SLR_INVOKE_MSI);
    finally

    end;
  OleCheck(AShellLink.GetIDList(IDList));
