General :: How To Prevent Piracy Of Database
May 23, 2013
If you are to sell a db. What have people done to stop one person copying it to their mates.
I have a way in which they send me their name,lastname and email. I then have a separate db that genertates a code based on a maths calculation. The users db does same calc. Then a comparison is done. if they match the code they entered goes green. if codes not right it goes red.
I also have macro that swap tables round when run. so by default its limted to 10 records. When swapped its unlimted.
I just cant link the 2 functions. Ideally some way it will see the green code and then run the macro to swap tables to a full db.
Then the customer has a full db and is also tied to their name etc...

I have a split database. I have secured the mde sufficiently but I need to secure the back end so that no one could link to tables in it. If I introduce a password to the back end is this going to require those using front end to supply the password? If not then this could be good solution.
As the database is on the network drive, is there any other way to prevent people to link to the db? Can I hide the db in the network drive? Or should I hide tables in the BE. Should these still be available to be linked?

I have built a database and within it my queries I use for reporting make tables in a separate database. This allows me to work in my data base and update info as needed. My problem is that my make table queries wont run if anyone has one of the report pivot tables open. I have added macros to all the Excel files that pull from the reporting DB but I still have several times when I cannot update because someone is using the pivot table, Is there a way to allow me to update the report DB's while the pivot tables are open? I have tried using manual refresh methods and disabling auto update on open but the result is the same.

Twice a year, a database of mine is accessed and put too use by various staff within a time range of 1 week. the database is on a shared drive and in a location which can be accessed by all.
The staff access the database from different workstations and in some instances at the same time.
This has only led to issues in the database being copied and then confusing staff on what database to click on thus i have 2 databases which i then have to sift through and copy/paste into the correct one.
I want to know the best way i can:
1) Prevent multiple users accessing the database at a time.
2) making a copy of the original and typing into a separate database.

Hi,
Does anyone have any ideas on how I might prevent a database from being copied. I have an application that I have set up with a number a tools to prevent exporting to an empty Access container, and from accessing the database design via the ShiftBypass feature, but the database can still be copied in its entirety. In some situations I would like to be able to add a feature to prevent this. Any suggestions?

Hi,
I created the database, which shared by multi-user. But, my user have a problem to open it. When user1 open the database, user2 cannot open it, I did not remember the error message, it is said that Admin (computer name) prevent you to open the database. But, if the user1 switch another application program (the database file is still opened), user2 can open the database, then both users can access the same database file.
Why do we have this problem? How can I fix it?

I need some code that checks if i already opened the database. I can't use the /EXCL option because 10+ people are also using it.
I had this code when working with Acc97 but i seem to have lost it.:(

I have set up a database that each user will put on their own computer, as it builds a running list made specifically for that user of chosen items to be exported to Excel, and because the remote locations have issues when accessing a shared network.
The db verifies the network user ID against a table to allow it to open. This to prevent any unauthorized user from accessing, and if db was copied or forwarded, only authorized users could see the data.
If the user is not on the list, it advises "Not an Authorized User", then exits Access. (I disabled the shift on opening, hid navigation bar, etc.) When further testing this security, I realized that even though users can access only the forms that I allowed, if they were to open another Access db, they could link or import the main table.
So all of my security precautions are for naught, as anyone with access to the db could see the confidential data. Even if they were not valid users, they could still get to the data if they knew how to import from another db. Is there any way to lock down the main table, so that it cannot be exported? Or be imported into another database?

On Microsoft Access 2010, I am creating a database project for a DJ booking system (not for professional use) and wondered how you can stop double booking from occurring that would provide you with an error message that I could personalize.
My current booking file looks like this:
Booking ID - Primary Key
Customer ID (Linked to customer table)
Venue ID (Linked to venue table)
Date Booked
Set Up Time
Start Time
Finish Time
Party Type
Discount Code
At the moment I have the date booked as Indexed (No Duplicates) however this gives me a long error message that I can not personalise.
Access 2010...

I have a mainform (F_main) and a subform associated (F_place).
F_place is the form of the table T_place.
T_place is linked to F_main by the field "BizNumber". I also have the field "Place" and of course the "Place ID" (primary key) in T_place.
"Place" in linked to a combobox (in F_place).I want to avoid, at a given "BizNumber", the same "place" to be entered in the F_place.

I am supposed to make a database for a hotel system, how I could prevent double bookings.
My Reservation Table has the following fields:
Reservation No. (PK)
Room No. (FK)
Customer ID (FK)
Payment ID(FK)
Reservation In Date
Reservation Out Date
Together with preventing double bookings is there a way automatically that can mark in the Room Table, the status as "available" or "booked" automatically by looking at the date today?

I want to lock archive records so that they can't be edited, however I want them available to users for viewing. So for example if the file is "closed" the record can not be changed.

I just finished a small Access-2013 database (accdb format).
Now I want to make it available to users.
How do I make an 'executable' (meaning that tables, forms, ... cannot be opened in design mode)?

Creating a database for processing survey data into a report format. We receive these reports as paper copies, which are then scanned in using Remark Office OMR. This results in a table of data, which is intended to be appended to the existing table in the database using Save As --> Access 2007, selecting the database and target table, clicking save as, and then selecting 'Append' from the subsequent popup.
What I want to know is: Is it possible to disable/otherwise prevent the 'Overwrite' option in this window from being selected? Can I make the table or database in such a way that data can only be added, not edited or deleted?

I'm creating an equipment hire database, and I was wondering how I would not permit overlaps of equipment hire ie. equipment being borrowed before it is returned. I have a query that lists all bookings that overlap, but I am unsure of how to implement this into the table to prevent overlaps.
The SQL for the query is as follows:
SELECT Bookings.[Booking ID], Bookings.[Instrument ID], Bookings.[Borrow Date], Bookings.[Return Date], Bookings_1.[Booking ID], Bookings_1.[Instrument ID], Bookings_1.[Borrow Date], Bookings_1.[Return Date], ([Bookings_1].[Borrow Date]>[Bookings].[Return Date]) Or ([Bookings_1].[Return Date]<[Bookings].[Borrow Date]) Or ([Bookings].[Instrument ID]<>[Bookings_1].[Instrument ID]) Or ([Bookings].[Booking ID]=[Bookings_1].[Booking ID])

In month-end posting - I basically delete all the records from my transaction file. And in doing so - it seems to be resetting the auto number index - which is causing me major problems.
The resetting of the index after deleting all the records is normal.
I am working in VB 2010 - using a 2003 MS Access database.

Database: Access 2007
I have designed a touchscreen input system using Visual Basic.net and this writes to an Access Database. Each Touchscreen has its database locally so it can still work even if there are Network problems.
Now what I would like to do is have all these local databases write to a central database say every minute but only write new records to the central database. The Central Database can either be Access or SQL.
What is the best way to do this?

I have been working on a database for over a month now, and my boss just threw a monkey wrench in my work. I believed that the Metal Market Prices would be entered once a week in the current DB. My boss informs me today that he wants an employee to go in every morning and enter that days Price for Each Metal with respect to many different markets.
There is a total of 12 metals, and 5 markets. I need the data to be stored first by date, then by either market or metal, and lastly by which ever isn't used second (Either: date-market-metal, or date-metal-market). I think the Latter of the two methods makes the most sense. Is it possible for my current DB to lookup values from the Metals Database based on date-metal-market?
