Form Security
Sep 8, 2006
Hi there,
I have a number of forms which I wish to password protect. Currently I have done this but the password is hard coded. I need to change this so that I can create a smaller like control panel form that allows some to change the different passwords.
My current problem is changing the hard coded passwords to use a variable instead. I thought to use a Public variable which is in a normal module (not class) however I am a little stuck as I dont know what would be the best way of setting and storing the value of that public variable.
Could anyone give me some advice please?

I've read and gone though quite a few of the scrips and examples for creating logins and security and i'm getting to the stage when i need to have good understanding of the different methods.
Some of the examples whilst create a user login do not really allow for security within the database whilst the build in security wizard would appear to offer that functionality.
I am thinking that I will use the Workgroup file and that method. My question is am i able to utilise the fact that if a person 'AdamA' logs onto the database which is built into the workgroup security file. am I then able to take 'AdamA' to populate a table which records actions by a user? (I can't seem to find any thread or book reference to doing this)

I have a form used for holding purchase information - the purchase order number, date etc. and the subform holds the order line items. Each order line item in the subform has a RECEIVED field check box on it, to denote when the item has been delivered.
I need to allow the storeman access to the form/ subform but only allow him to change the subform 'received' field to say that the goods have been delivered. All other fields on the subform should be locked - How would I do this?
It is not sufficient to disable controls in the subform in the Form_Load() event - this does nothing.

Hi all.
Once upon a time I stumbled upon an example form or selection or forms that I merged that allowed the admin user to add and modify user accounts that were set up using the User-Level Security wizard. The form showed the user accounts and group there each were in both of which could be changed or added to as weel as passwords changed or set without going through the full toolbar selection method.
I have since deleted this from my computer in one of my random clean ups but have since been asked for it again. Does anybody have any knowledge of this form or where I might be able to find it?
Cheers

I have a form based on a table where social security numbers are entered. I would like to enter a social security number on the form and once it's entered the first 5 digits are masked. When I go to the table I would like to see the complete social security number displayed. Is this possible? Can the control source on the form be formatted to hide the existing social security numbers as well so they don't have to be rekeyed with the new format?
Thank you in advance:cool:

Hello,
I have a db that I want to password, so that anyone pressing either F11 or holding shift down at the start, will be prompted with a password.
.....But, I want the user to be able to see the start-up form and associated forms without having to enter a password.
Is this something that is possible to do in Access97?
I have searched the forum for an answer, but can't find anything.
Thanks, Steve.

On my form frmEmployeeDetails I have a text field that is named SSN for social security numbers. I have used the mask on it so it automatically inputs dashes. I am attempting to hide all but the last four digits of the ssn. This is on the on current event of my form.
Code:
'Hide SSN
Dim strLSSN, strSSN As String
strLSSN = Right(SSN, 4)
strSSN = ("***-**-" & strLSSN)
Me.SSN = strSSN

I am looking to lock my database until the user puts in the correct credentials.

I am relatively new to Access and VB. I am trying to create a log-in system that assigns a security clearance to each user and then restricts access to certain forms and reports based on security clearance. Right now, I have set up the log-in system - that seems to work fine. But when I try to lock the form based on security clearance, I get the 2450 - Form Not Found - error.
The code I am using on the form is as follows:
Private Sub Form_Open (Cancel As Integer)
If Forms!frmLogin!cboUser.Column(4) <> 1 Then
MsgBox "You do not have access to this form", vbOkOnly
DoCmd.Close acForm, "formname"
EndIf
End Sub

Is it possible to do this through vba. If security is setup for all the tables and a user goes in and creates a new table, can that table have security applied to it using code?
So maybe the creator of the table has read/write privileges but everyone else only has read only.

Hi
I am experimenting in creating security of a database, and elements within.
I started by creating a user account with a password. I then made a few mistakes, so wanted to delete the mdb, and start again.
However, when I now try to create a new database, or even open a pre existing database, I am asked for the user and password created in the now-deleted mdb.
Apart from the fact that it shouldn't ask for the user name and pasword created in the first database, I am sure it doesn't accept the password I intered in creating the account.
The easy solution would be to delete the file where Access stores user accounts. Where is it, and is it protected, such that I can't delete it? And even if the user name and password still exists somewhere, it should only apply to the database in which it was created, shouldn't it?
Thanks
Robert

Hi all,
Just looking for a little advice on data protection. I have a split database which is accessed from the front end (forms only). All data is stored on the back end, which is hidden away from the user.
The database is password protected, and both sides use a login authentication to avoid unwanted access. However, the usernames and passwords are easily retrievable by opening the database a text document.
Any ideas on how to make this more secure?
Cheers

I try to play Security.
After I created it, the shortcut is created on the screen.
Everytime needs to click the shortcut to login it.
But, when I go to database file, and then click it, it does not work, it will show the following message:
You do not have the necessary permissions to use the <name> object. Have your system administrator or the person who created this object establish the appropriate permissions for you. (Error 3033)
You do not have the necessary permissions for the specified object. To change your permission assignments, see your system administrator or the object's creator.
So, is it ony the shortcut to login it?
if delete the shortcut uncarefully, how to do it??
Thanks.

Hi,
Problem 1:
I setup a security, stored the security file and other files in the drive D:
it works.
after I move the files to the drive C:, then it doesn't work.
Why it doesn't work?
Problem 2:
After I created security, there are acc.mdb, acc.bak, and Secured files, right.
how can I add this link:
"C:Program FilesMicrosoft OfficeOffice10MSACCESS.EXE" "D:acc.mdb" /WRKGRP "D:Secured.mdw" in the target to the acc.mdb file.
Because when it doesn't work, and then I created a shortcut of the acc.mdb file, then add the above code. Then it works, it give out the prompt.
Does any method instead of this, better than this?
Please let me know, thanks.

Hi
When using security login, can we logout and then login to the database without shutting down the database and re-opening.
Such as using a button to logout and then another to login.

Hi,
I have now finished my system that will run on a windows network. I now need to get the security setup so different users can access different pages.
I have set a list of users and specified what forms/tables they can access. The problem is, how does access know who is accessing the pages? For example, i have set 2 users - Dave G & Dave S - I have given Dave G access to the admin forms as he is the admin and I have given Dave S access to the general data input forms.
How is this enforced? How does access know which person is opening the forms. Unless access asks the user to login using their user name set in access, I cannot see how it can manage what users can do what.
Thanks

First of all, i am pretty new to this....
We have a few access databases in a network. More and more people in our organization are using the databases so I am learning to create some user-level security.
We have access 2000.
Access links to a WIF to create user-level security.
But I think there is an easy way that anyone can get pass that.
Even if I have set all the groups and users privileges and restrictions, anyone can simply switch from one WIF to another WIF, then they would have changed all their privileges and restrictions.
Am I understanding this correctly?
If so, what can I do better secure the database.
Another question:
How can I prevent someone from simply copy/delete the access file from windows? I am afraid that someone, maybe a disgruntled employee or even myself making stupid mistakes, delete the whole access .mdb file, and I would loss everything.
I do backup the file, but even if I back it up every night, if something like this happens, i would have lost a whole day of work.
Your advice are highly appreciated.
Thank you all for your help.

Hi,
I followed the security wizard and everything worked fine. However, when I move the database to another computer or another folder, it prints this message:
'You don't have the necessary permission to use (path)...'
Is there anyway to avoid this please?
Thanks,
B

Access security is really very confusing, thought I had conquered it but I was wrong. I have been playing with a test DB. How on earth do you reset a password for a user? I just can't see where you go to assign a new password.
Managed to clear the password but then got stuck.

Hi,
I have a question for user-level security and workgroup.
Suppose we setup user-level security and have a workgroup with storing all username, password, and groups,
if adminstrator want to change one user permission, let's say that change the user permission from update to read permission only, then the user should only have read permission, right. However, previously, the user copied the workgroup file himself before adminstrator change his permission, if he apply to his copied workgroup file, and log in the database, he can still have update permission.
So, how do I prevent the user using his copied workgroup file for the database?
How can I solve it?
Thanks.

Hi again
The security on my database so far is justthe standard everyone has a user name and a password, no one can alter the design of a form apart from me
I am just wondering if there is any way that I can prevent people viewing and altering tables, queries etc. It would be good if when the open the database the main form comes up so they can navigate from that and they are always taken back to this and they can never see the database window
Does this have anything to do with front end and back end databases?
Sorry its a bit vauge but hopefully you will know what I mean
thanks
