[AccessD] Add-In Express 2009 for MS Office and .NET

Shamil,
That sound good but I should mention that XML is extremely slow for large
table as well as occupying large disk space, but the time taken is
exponentially longer that xls and for what purpose?  After all, if it is for
backup, xml offers not advantages but lots of dis-advantages.

Up to you though.



Max

Hi Max --

Thank you for code samples - I plan to make it a bit different for first
version - something like the code in P.S. of this message (Export), and
Import will be posted in the other message.

Thank you.

P.S. MS Access DB Export code (watch line wraps):

Option Compare Text
Option Explicit

Public Sub ExportObjects()
'
' 1. Exports Queries, Forms, Reports, Macros, Modules as
'     text files into \Objects subfolder
'
' 2. Exports Tables as
'     xml files with schema into \Objects subfolder
'
' 3. Exports MSys* tables as
'     xml files with schema into \Objects\MSysTables subfolder
'

Section 3 - Import

That's the lot now.  No form or user interface. I hope it works ok, seem ok
on my test system but caveat emptor as  always.
