How to retrieve system oledb Provider list

In my app I have to list of "oledb provider" to let the user choose the connection method. As follow:
1.Jet 4.0 OLE DB Provider
2.OLE DB Provider for DTS Packages
3.OLEDB Provider for Indexing Service
4.OLEDB Provider for ODBC Drivers
5.OLEDB Provider for OLAP Services
6.OLEDB Provider for Olap Services 8.0
7.OLEDB Provider for Oracle
8.OLEDB Provider for SQL Server
9.OLEDB Simple Provide
Which doesn't not support must be disabled.
Use which funciton can retrieve the Provider list of system or something like that.
