Type Property Example (Property) (VB)

See Also

This example demonstrates the Type property. It is a model of a utility for listing the names and types of a collection, like Properties, Fields, etc.

We do not need to open the Recordset to access its Properties collection; they come into existence when the Recordset object is instantiated. However, setting the CursorLocation property to adUseClient adds several dynamic properties to the Recordset object's Properties collection, making the example a little more interesting. For sake of illustration, we explicitly use the Item property to access each Property object.
