title: WPD Service api implimentation (Status Service) to get free space on WPD device
body: <p>I want to get the free space on the WPD device. I am trying to implement the WPDServiceApi. I am currently implementing the status service of WPD services. i picked up the the code samples from Windows7DEK.   There are lots of type mismatches coming into existence during compilation. I am not able to build that sample at all. Initially there were a lot of missing includes which i have resolved successfully. Now i am getting type mismatches like (PSLGUID) was expected and sample is just sending (GUID) type parameter. This is just a random example. Anyone have any experience on status service? i just want to get the free space on the device.   </p>
