8. Example Scenario A new type of erase is supported by hardware Developer’s goal is to enable this new functionality through Windows for the end user Strategy Create an extension of IMAPIv2 to support the new erase method Expose functionality to users through a shell extension Solution Analysis Extend IMAPIv2 at the Disc Format level Does not involve user content Sends a specific sequence of logical commands to the device Implementation involves media-specific information

9. interface IEraseSample : IDiscFormat2 { // properties HRESULT Recorder([in] IDiscRecorder2 * value); HRESULT FullErase([in] VARIANT_BOOL value ); HRESULT ClientName([in] BSTR name); // methods HRESULT EraseMedia(); } Simple interface that extends IDiscFormat2 Includes new scenario specific methods and properties

10. HRESULT PerformErase(VARIANT_BOOL vbFullErase, IDiscRecorder2 *pDiscRecorder) { // create the new object // create the new object CoCreateInstance(CLSID_EraseSample, CoCreateInstance(CLSID_EraseSample, NULL, CLSCTX_ALL, NULL, CLSCTX_ALL, IID_PPV_ARGS(&pErase)); IID_PPV_ARGS(&pErase)); // use IDiscFormat2 method to ensure the operation is supported // use IDiscFormat2 method to ensure the operation is supported pErase->IsCurrentMediaSupported(pDiscRecorder, &vbEraseSupported); pErase->IsCurrentMediaSupported(pDiscRecorder, &vbEraseSupported); if (vbEraseSupported) { if (vbEraseSupported) { // attach the standard disc recorder // attach the standard disc recorder pErase->put_Recorder(pDiscRecorder); pErase->put_Recorder(pDiscRecorder); // set the appropriate properties // set the appropriate properties pErase->put_FullErase(vbFullErase); pErase->put_FullErase(vbFullErase); pErase->put_ClientName(SysAllocString(L"EraseShellExt")); pErase->put_ClientName(SysAllocString(L"EraseShellExt")); // perform the erase! // perform the erase! pErase->EraseMedia(); pErase->EraseMedia(); }}
