Hi

Create a button and place this behind the OnClick event

   Call Shell("""C:\Program Files\Microsoft Office\OFFICE11\MSACCESS.EXE""
""C:\Documents and Settings\UKOPS\My Documents\NAMEofDATABASE.mdb""", 1)

Notes
Microsoft Office\OFFICE11\MSACCESS
I assume you are using Office11
If not change this

C:\   I assum you are working on C  -
if not change this

C:\Documents and Settings\UKOPS\My Documents\NAMEofDATABASE.mdb
Insert the full path to the DB
A tip = if you don't know the path.  Click Start / Run / Browse to the DB
then click Open.  DON'T RUN - but click the the path in the run dialog box
and paste it into the code above.

Have fun

Hope this helps
