IVdsProviderPrivate::OnLoad method (vdshwprv.h)

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Prompts the provider to initialize itself, and passes a callback object that the provider uses to get necessary interfaces.

Syntax

HRESULT OnLoad(
  LPWSTR   pwszMachineName,
  IUnknown *pCallbackObject
);

Parameters

pwszMachineName

This parameter is reserved.

pCallbackObject

Pointer to a callback object.

Return value

This method can return standard HRESULT values, such as E_INVALIDARG or E_OUTOFMEMORY, and VDS-specific return values. It can also return converted system error codes using the HRESULT_FROM_WIN32 macro. Errors can originate from VDS itself or from the underlying VDS provider that is being used. Possible return values include the following.

Return code/value Description
S_OK
The provider is initialized.
VDS_E_INITIALIZED_FAILED
0x80042401L
The provider failed to initialize.

Remarks

VDS calls this method immediately after calling the CoCreateInstance method on a provider.

Implementers must implement this method. Invoke the IUnknown::QueryInterface method to query for the IVdsAdviseSink interface.
