Remarks
COM Signature
From vsshell.idl:
HRESULT IVsToolboxDataProvider::IsSupported(
[in]IDataObject* pDO
);
The environment calls each registered data provider with IVsToolboxUserDataProvider.IsSupported to determine whether any of the data providers support the new data object. If a data provider supports the data object (that is, returns S_OK), then the data object is added to the Toolbox.
