It is a Visual Basic 5.0 tool for programmers that  need to update the structure of a database 
by program keeping the data inside the database. (It is for Access databases 
3.0 - from Access 97 -)
It is useful in that cases where the programmer has distributed some versions 
of a program, and later, in newer versions he has made changes to the 
structure of the database; like add tables or add (or delete) some fields to
a table, change relations or index keys. When there are changed fields types 
or field size of text fields, it automatically converts data types in all 
the records stored in that table.

No installation is required, just add the ocx file with the project, 
components menu option in Visual Basic (pressing the button browse).

Version: 1.0.
It is shareware, freely distributable.

Details:
The OCX compares the structure of the database, set by DBToUpdate property 
with a reference database archive set by DBRef property.
The reference database file set by DBRef property may be a database without 
data, a blank database just to reference about the structure (anyway 
no matter if it has data).

Sample usage:
DBUpdate1.DBRef = "C:\MyProgram\Ref.mdb"
DBUpdate1.DBToUpdate = "C:\MyProgram\MyDB.mdb"
DBUpdate1.Update
