I believe that under data base utilities, there is a menu item to create an mde file. I like to structure the project to wind up with 3 files.

  1. Data.mdb
  2. App.mdb
  3. App.mde

Data.mdb is nothing but tables. typically, this will sit on some shared drive in a lan environment

App.mdb contains your VB source code, queries, forms, etc. You link this .mdb to all of the Data.mdb tables.

App.mde is the "Compiled" version of app.mdb. This is what you distribute to the individual uses desktop or put a single copy on the share. No source code is accessible.

Thanx for the suggestion but I don't know how to wind my VB files in App.mdb file. Secondly my application will be used by SINGLE user on Stand alone computer with two major components i.e. VB Forms and Access DB. Still looking for solution...

The preference is to separate app from data, then just distribute the data.mdb and the app.mde.

If you have both app and data in one mdb and don't want to split it, you can still use the "create mde" item in the "data base utilities" menu to create an mde that doesn't have any code.

It's been a while, but I think I had used some ocx thing by Sheridan, and some installation products - InstallShield, InStyler, etc.

You may want to check out the developer tools section of pcworlddownload.com. they usually have a pretty good selection and it would be more current than my recollection.
