Hi,
Can anybody tell me how to use VDS in order to perform format operation on any volume connected with your computer.
I used the following code, but didnt achieve the solution.
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);
// hResult = pVdsVolume->AddAccessPath(TEXT(“G:\”));
if(SUCCEEDED(hResult))
AfxMessageBox(L"Add Access Path Successfully");
else
AfxMessageBox(L"Unable to Add access path");
//UUID of IVdsVolumeMF {EE2D5DED-6236-4169-931D-B9778CE03DC6}
static const GUID GUID_IVdsVolumeMF = {0xEE2D5DED, 0x6236, 4169,{0x93, 0x1D, 0xB9, 0x77, 0x8C, 0xE0, 0x3D, 0XC6} };
hResult = pService->GetObject(GUID_IVdsVolumeMF, VDS_OT_VOLUME, &ppObjUnk);
if(hResult == VDS_E_OBJECT_NOT_FOUND)
AfxMessageBox(L"Object Not found");
if(hResult == VDS_E_INITIALIZED_FAILED)
AfxMessageBox(L"Initialization failed");
// pVdsVolume = reinterpret_cast(ppObjUnk);
if(SUCCEEDED(hResult))
{
// hResult = pVdsVolume->AddAccessPath(TEXT(“G:\”));
if(SUCCEEDED(hResult))
{
IVdsAsync* ppVdsSync;
AfxMessageBox(L"Formatting is about to Start…“);
// hResult = pVdsVolume->Format(VDS_FST_UDF, TEXT(“UDF_FORMAT_TEST”), 2048, TRUE, FALSE, FALSE, &ppVdsSync);
if(SUCCEEDED(hResult))
AfxMessageBox(L"Formatting Started…”);
else
AfxMessageBox(L"Formatting Failed");
}
else
AfxMessageBox(L"Unable to Add Access Path");
}
_SafeRelease(pVdsVolume);
}
else
{
AfxMessageBox(L"VDS Service Cannot be Loaded");
}
}
}
_SafeRelease(pService);
Please, help me if anybody knows the solution.
Thanks
