MS Access Object Security

Today’s post is based on a question that I received.

We are going to assume that there are multiple users who have rights
to view different database objects.

So in this example there are 3 user logins with different rights to access 3 forms and 3 reports.

Here is an overview of the database setup:

MS_Access_Object_Security_1

This is tblLogins:

MS_Access_Object_Security_2

This is tblAdmin:

MS_Access_Object_Security_3

Notice that all you really need to do is check whether the user has access to the object.

If you want, you can assign the permissions based on groups, instead of user by user. Then you can assign the users to groups, and the groups can have the permissions to the objects.

On the “Open” event for each form, place the following code:

On the “Open” event for each report, place the following code:

On the “Open” event of each database object we are using the “Allowed” function to let us know if the user is allowed to open the database object.

The “Allowed” function is used by a number of forms and reports, so we put the “Allowed” function in a module called “basSecurity” by itself.

Here is the “Allowed” function:

This function will check the tblAdmin table to see if the user is allowed to open the requested object.

basSecurity also has a modular scope variable called “m_LoggedInUser”, to store the user name of the currently logged in user.

Here is the screenshot all together:

MS_Access_Object_Security_4

To test and open all the forms and reports I am using a form called “frmMain”:

MS_Access_Object_Security_5

…and here is “behind the scenes”:

MS_Access_Object_Security_6

That’s about all, let me know if you have any questions.
