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.
