auto SAVE drawing when user closes it

user closes the drawing (unsaved). i want to make sure that drawing
is saved no matter what, even if user said 'no' on 'save file?'
dialog... i know it can be done in objectarx (and i've tried), but it's
too complicated. anyone knows quick (or not quick but working) way to
do that? thanks for any suggestions or comments...

why do i need that: we're doing GIS, so changes in drawing are
reflected in database, and if drawing is not saved - we have
inconsistency...

In VBA, open the VBA editor and in ThisDrawing under the AutoCAD
objects in any project.

Create the BeginClose event and place the code ThisDrawing.Save

eg.
Private Sub AcadDocument_BeginClose()

ThisDrawing.Save
End Sub

Regardless of what the user chooses 'Yes' or 'No' to saving the file
upon closing the drawing, the drawing will be saved


I hope this helps
