IDCInfo Interface

IID_IDCInfo

{0C733A9C-2A1C-11CE-ADE5-00AA0044773D}

IDCInfo provides methods that can be used to furnish the Data Conversion Library with information, such as provider version, that can affect how conversions are performed. If IDCInfo::SetInfo is not called, the Data Conversion Library assumes the provider is an OLE DB 1.0–compliant provider.

IDCInfo can be obtained by calling QueryInterface from IDataConvert using IID_IDCInfo. IDCInfo includes the methods described in the following table.
