Prototype 

ApplyFileWithParms( parms As ULConnectionParms ) As Boolean
Member of UltraliteActiveX.ULDatabaseSchema

Description

Caution 
ApplyFileWithParms is very safe in the hands of an informed programmer. Do not delete columns unthinkingly unless you are willing to accept data loss, as data loss can occur under a number of circumstances including (1) if columns are deleted, or (2) if the data type for a column is changed to an incompatible type or (3) if you upgrade an 8.0.2 database using ApplyFile in UltraLite 9.0.
Parameters 

parms    The object identifying the schema file to apply.

Returns 

True if successful.

False if unsuccessful.
