Applies To

TFMAccess, all VA FileMan data access components

Declaration

property ErrorList : TList;

Description

A TList of TFMErrorObj objects. This TList is populated if the VA FileMan data access component encounters one or more VA FileMan errors during a server call.

Data access components automatically clear their ErrorList property immediately before making any server call. After a server call, you can:

• Check the TList Count property of the ErrorList to see how many errors occurred.

• Use the DisplayErrors method to display errors to the user.

• Loop through the TFMErrorObj objects in the ErrorList after a call, if you need to branch based on the presence of a particular error.
