Programming Notes
=================
The VBQuery sample illustrates how you can use the Query and Util
Automation objects of the Query Helper API to build applications
that query a catalog. The sample can process queries specified in any
of the three query languages:
* Query Language Dialect 1
* Query Language Dialect 2
* Structured Query Language (SQL)
In addtion, the sample uses ADO objects to handle the recordsets returned
by the Query Helper Automation objects.
This sample also demonstrates making a DLL call to the LocateCatalogs
function of the OLE DB Help API. The application uses this function to
locate catalogs suitable for the scope specified by the user.
