Hi I need help improving a VBA code that someone created for me in 2012using Access 2010 while working at a different agency using a different network server. The code searches for a user's network name in a table called "tblAccess", if their network name isn't in the table, the users will get a message saying that they are not authorized and kick them out of the database. For users who are in the tblAccess table, the objects (tables and etc) are automatically hidden depending on a user's access level. There are two fields in the tblAccess - NetworkName and ScreenAccess (this grants access to certain forms using commands). Also, there is another code that searches for a user's network name in a table called "tblAdmins", if their network name isn't in the table, users will not have the ability to see the objects (tables and etc). The way that this happens is that there is a button that unhide the objects when clicked if the user's name is in the table. If a user name isn't in the table, the unhide button isn't visible. There is only one filed in the tblAdmin table - NetworkName.

The issue that I am having is that the code isn't working 100% correctly here at the new location. For one, at the old location, the code prevented users from right clicking the form to see the form in design view. Now, users who have access can right click the form and view the form in design view. For two, the code only prevents people who are using Access 2010. For people using Access 2013, they are able to access the database although their network name isn't listed in the tblAccess table. Below are the codes:
