Hi bash - thanks for your reply.

I am setting security via Access - I have no problem doing this.

I am also aware that users would not be able to (for example) amend bound fields if they have an insufficient security level.

What I am trying to do is limit a users actions at the earlist possible opportunity by checking their security permissions at the start of the program.

For example, if a user only has "Read" permission for a table then I want that user to be able to see all the data, but I want to disable our "Add new record" button or "Edit record" button. Equally, to enable the buttons if the user has "Insert" or "Update" permission.

Reading and applying these permissions in this way is not a problem if the table is at the front-end. I am having a problem when the table is at the back-end.

What you say makes sense - I will give it a try.

Thanks again
