# Find Method Example (VC++)
This example uses the [Recordset](../../../ado/reference/ado-api/recordset-object-ado.md) object's [Find](../../../ado/reference/ado-api/find-method-ado.md) method to locate and count the number of business titles in the **Pubs** database. The example assumes the underlying provider does not support similar functionality.
