The initial release of Microsoft Internet Explorer 5.0, containing MDAC 2.1.1.3711.6 (IE5), might generate an application violation when an ActiveX® Data Objects (ADO) consumer application attempts to connect or to test a connection by using Microsoft Data Links. Specifically, this issue affects those OLE DB providers that do not have the optional OLEDB_SERVICES registry entry. The Microsoft OLE DB Provider for DB2 and the Microsoft OLE DB Provider for AS/400 and VSAM are adversely affected by this issue. This problem is resolved in Internet Explorer 5.0a and MDAC 2.1.1.3711.11 (GA).
MDAC 2.10.3513.2 also included the first and last release in MDAC of the Remote Data Objects (RDO) and Remote Data Control (RDC). RDO is a COM wrapper of ODBC. Microsoft Jet uses RDO in its ODBCDirect technology. The RDC was a data source control that could be used in Microsoft Visual Basic and Microsoft Visual C++ to bind controls on a form or a dialog to an ODBC data source through RDO.
Internet Explorer 5.0a installs a subset of MDAC 2.1.1.3511.11. This subset is a limited client installation that contains only core ADO, OLE DB, and ODBC. It does not contain Microsoft Jet or any drivers or providers found in MDAC 2.1.1.3711.11 (GA) and later.
There are no changes in the header files in different released versions of MDAC 2.1.x. Continue using the headers from the MDAC 2.1 SDK Update and the MDAC 2.0 SDK stand-alone.
