Indicates the name of the object or application that originally generated an error.
Return Value
Returns a String value that indicates the name of an object or application.
Remarks
Use the Source property on an Error object to determine the name of the object or application that originally generated an error. This could be the object's class name or programmatic ID. For errors in ADO, the property value will be ADODB.ObjectName, where ObjectName is the name of the object that triggered the error. For ADOX and ADO MD, the value will be ADOX.ObjectName and ADOMD.ObjectName, respectively.
Based on the error documentation from the Source, Number, and Description properties of Error objects, you can write code that will handle the error appropriately.
The Source property is read-only for Error objects.
