What library is needed to link with IVdsDiskOnline addressmadan 12/2/2008 6:46:09 AM Hi All, I have written a small program which will load a VDS Service on Windows Server 2008 and then it will check for any Offline disks. If the disks are offline, then I'am making them Online using the VDS's API IVdsDiskOnline::Online(); But, I'am getting the following link error: error LNK2001: unresolved external symbol _IID_IVdsDiskOnline I have downloaded the Platform SDK for Windows Server 2008 and gave proper paths to the libraries in that for the program to link correctly. MSDN says that VDS (Virtual Disk Service) requires "uuid.lib". To quench my curiosity, I have opened the uuid.lib in a binary editor and to my surprise found that there is no definition for IVdsDiskOnline() interface. MSDN says that this API is only for Windows Server 2008. But I have already downloaded the Platform SDK for Windows Server 2008! So, why then the link error is appearing during build? Is it because the Platform SDK for Windows Server 2008 is not having the required definition or some other problem? Wonder, if anyone has solved this problem or faced it atleast. Please help me. Regards, Madan Mohan Cheemakurthi

Instead of using IID_IVdsDiskOnline try using __uuidof(IVdsDiskOnline) -- http://www.chrisnet.net/code.htm [MS MVP for DirectShow / MediaFoundation]
