问题描述

谁能告诉我如何使用VDS对与计算机连接的任何卷执行格式化操作.

在此先感谢

Hi,
Can anybody tell me how to use VDS in order to perform format operation on any volume connected with your computer.

Thank in advance

推荐答案

VDS在硬盘而不是CD/DVD上工作.
查看 IMAPI [

VDS works on hard disks, not CD/DVD.
Look at IMAPI[^] for targetting CD/DVD

仍然感到困惑. Microsoft对此进行了详细说明: http://msdn.microsoft.com/zh-我们/library/aa819125(v=VS.85).aspx [

Still confused. Microsoft elaborates on this: http://msdn.microsoft.com/en-us/library/aa819125(v=VS.85).aspx[^]

这是我的代码，通过该代码我可以成功地初始化VDS服务并获取包，但是当我在IVdsPack对象上调用QueryVolumes时，我能够获取IEnumVdsObjects，但无法从IEnumVdsObject :: Next获取IUnknown *，其中IUnkown * = NULL会返回S_FALSE.因此，此IUnknown *不能用于IVdsVolume的QueryInterface

帮助我摆脱这种情况

here it is my code through which I am successfully initialize the VDS service and get the Packs but When I call QueryVolumes on IVdsPack Object, I am able to get IEnumVdsObjects but unable to get IUnknown* from IEnumVdsObject::Next reutrns S_FALSE with IUnkown* = NULL. So this IUnknown* cant be used to QueryInterface for IVdsVolume

Help me out to get out of this situation

HRESULT hResult;
IVdsService* pService = NULL;
IVdsServiceLoader *pLoader = NULL;

//Launch the VDS Service
hResult = CoInitialize(NULL);
if( SUCCEEDED(hResult) )
{
    hResult = CoCreateInstance( CLSID_VdsLoader,
                NULL,
                CLSCTX_LOCAL_SERVER,
                IID_IVdsServiceLoader,
                (void**) &pLoader
                );

    //if succeeded load VDS on local machine
    if( SUCCEEDED(hResult) )
        pLoader->LoadService(NULL, &pService);

    //Done with Loader now release VDS Loader interface
    _SafeRelease(pLoader);

    if( SUCCEEDED(hResult) )
    {
        hResult = pService->WaitForServiceReady();
        if ( SUCCEEDED(hResult) )
        {
            AfxMessageBox(L"VDS Service Loaded");
            IEnumVdsObject* pEnumVdsObject = NULL;
            hResult = pService->QueryProviders(VDS_QUERY_SOFTWARE_PROVIDERS, &pEnumVdsObject);

            IUnknown* ppObjUnk ;
            IVdsSwProvider* pVdsSwProvider = NULL;
            IVdsPack* pVdsPack = NULL;
            IVdsVolume* pVdsVolume = NULL;
            ULONG ulFetched = 0;

            hResult = E_INVALIDARG;
            while(!SUCCEEDED(hResult))
            {
                hResult = pEnumVdsObject->Next(1, &ppObjUnk, &ulFetched);
                hResult = ppObjUnk->QueryInterface(IID_IVdsSwProvider, (void**)&pVdsSwProvider);
                if(!SUCCEEDED(hResult))
                    _SafeRelease(ppObjUnk);
            }
            _SafeRelease(pEnumVdsObject);
            _SafeRelease(ppObjUnk);

            hResult = pVdsSwProvider->QueryPacks(&pEnumVdsObject);

            hResult = E_INVALIDARG;
            while(!SUCCEEDED(hResult))
            {
                hResult = pEnumVdsObject->Next(1, &ppObjUnk, &ulFetched);
                hResult = ppObjUnk->QueryInterface(IID_IVdsPack, (void**)&pVdsPack);
                if(!SUCCEEDED(hResult))
                    _SafeRelease(ppObjUnk);
            }

            _SafeRelease(pEnumVdsObject);
            _SafeRelease(ppObjUnk);

            hResult = pVdsPack->QueryVolumes(&pEnumVdsObject);
            pEnumVdsObject->Reset();

            hResult = E_INVALIDARG;
            ulFetched = 0;
            BOOL bDone = FALSE;
            while(!SUCCEEDED(hResult))
            {
                hResult = pEnumVdsObject->Next(1, &ppObjUnk, &ulFetched);
                hResult = ppObjUnk->QueryInterface(IID_IVdsVolume, (void**)&pVdsVolume);
                if(!SUCCEEDED(hResult))
                    _SafeRelease(ppObjUnk);
            }
            _SafeRelease(pEnumVdsObject);
            _SafeRelease(ppObjUnk);
            _SafeRelease(pVdsPack);
            _SafeRelease(pVdsSwProvider);
