Description
Loads a recordset from a file.
Call LoadFromFile to load the recordset for the calling ADO dataset component from a file. If the loading operation fails, the current recordset is neutralized (set to nil (Delphi) or NULL (C++)), the dataset component remains inactive, and an EOleException exception is raised. If the attempt to load data from a file is successful, the ADO dataset component is automatically activated and the data made available.
FileName is a string containing the name of the file.
LoadFromFile closes the dataset component before loading the recordset from the file specified in FileName.
