)

	Record^ record
)

Parameters

record (Record): the Record to be validated

Return Value

null if the record is safe to delete; if another row refers to the primary keys of this row then error information is returned

Remarks

Validation does not check for the existence of the primary keys of this row in properties or strings. Does not check if a column is a foreign key to multiple tables. Works with read-write and read-only records. This method cannot be used with a View containing joins.

See Modify(ViewModifyMode, Record) for more remarks.

Win32 MSI APIs: MsiViewModify, MsiViewGetError
