Property group: Data Source Information

Property set: DBPROPSET_DATASOURCEINFO

Type: VT_I4

Description: Data Source Object Threading Model

A bitmask specifying the threading models supported by the data source object. A combination of one or more of the following:

DBPROPVAL_RT_FREETHREAD

DBPROPVAL_RT_APTMTTHREAD

DBPROPVAL_RT_SINGLETHREAD

Note In the case where additional threading limitations are imposed by underlying components, the threading model returned in this property might be stricter than the thread model registered under the provider's CLSID. OLE DB 1.x providers may set only one bit of this property, commonly to the highest level of threading supported.
