GetString Method Example (VB)

This example demonstrates the GetString method.

Assume you are debugging a data access problem and want a quick, simple way of printing the current contents of a small Recordset.


    'To integrate this code
    'replace the data source and initial catalog values
    'in the connection string

Public Sub Main()
    On Error GoTo ErrorHandler
