General :: How To Set Authentications To Different Users
Jul 3, 2012
I am new to MS access. I need to know - how to set authentications to different users. i.e. i have made a switchboard containing login form, and other forms of the database. all i want is to restrict user from accessing my main tables of DB.
When someone wants to enter data, he/she can use switchboard but with the restrictions not to see anything else. only administrator or people with user ID and password can have access to entire DB.
I am trying to implement a username and password system on my DB. What I have done so far is created a table with username, password, permission level and datestamp. So when the db is opened, the form pops up and someone has to sign in. When they hit the 'login' button, there is a field that will populate the time in which they signed in. This will also allow me to see who is logged in. When they are finished, they will end up on the login screen where there is a close button. When they hit the close button, the field with the datestamp will be cleared. This will allow me to know that the user is no longer on the db. Here comes the question, if a user just closes access without hitting my 'close' button, my datestamp field will not be cleared. I have tried using the "onclose" event, but of course i used 'me.datestamp = "" but the form is already closed, so it says 'can not change the value of this field.' How can i clear the value of the datestamp field for a specific user when a user closes the program the "improper" way.
The database: is for tracking computer issues (this part is complete), also I need to show the on call roster (mostly complete)... This will also have a time sheet that I need to be completed once a fortnight, however I would like it to auto populate the staff members logged information (I will get into that a little later).
Question 1: I do not want the users to log into the database, however I do want the database recognise who they are from their windows logon details.
I have developed a new database using Access 2003, which I need to roll out across various users. Some have XP, some Windows 7, and each of them has different size screens. I guess I will have to adjust the various forms to size to a particular users screen resolutions and sizes.
Is there any way of doing this within the database itself, or do I have have to adjust each form according to the local users PC specification?
Currently the system where I work is set up so that everyone has their own front end on the local network. I would like to change this because updating all of them takes a lot of time for me and skill level for users is too low for me to trust them with updating it on there own.
My question is this:
If I were to create a shortcut on everyone's desktop that linked to one front end would this be wise? I can't seem to get a straight answer from anywhere on the internet. I know most places say that it is better to have the actual front end on the staffs computer but that would make my job of keeping the database updated even worse because staff have multiple computers and this isn't my full time job.
If this is okay practice how many users would this be able to sustain? Currently we only have 6 users on the database with there own front end and it works great. I am planning on adding around 10 more users in the future but if needed they could have there own database as they are separate programs.
I used to have a handy tool called LDB Viewer or something like that with which I could see who is using my database. Now I've upgraded to MS 2010 is there a way to do the same?
i am having issues with certain users re references, I get weird errors when sending emails through Outlook, is there anyway running some code for me to check a users references?the below is what i have and everything works fine, so would like to check they have these

I'm an absolute novice at Access. I have a very simple (yet sufficient) database that lists our company's projects, tasks associated with those projects and when to invoice.
Our company consists of myself and my business partner. We both work from our (separate) homes. Our project files are stored in the cloud. This works well. We have investigated a server in the past, but found it to be cost-prohibitive and unnecessary for our business.
Is there a way that my business partner can have the Access database running at the same time as me, and make additions/modifications? I don't know how this would work in terms of updating/saving.
I know that Access probably permits around 20 or so users to simultaneously access the database before it start to become unfriendly. However, I have a database that would require 200 or so users grabbing around 1,000 rows of data via an Excel ADO connection to the backend tables.
So they would never need to physically go inside the Access database its self, but instead it would garb data by opening an ADO connection to the database > Grabbing the data > Closing the database connection.
Is this okay to do with around 200 users simultaneously querying the database tables via an Excel ADO connection?
I am about to allow users to access a database I redesigned for others to use.I am trying to save it as an ACCDE so they can't mess it up. The database is very very simple.6 tables each with only 4 fields or less... and none are related to one another
7 forms. 1 report. 0 queries... it's just a SKU generator.
When I attempt to save as ACCDE I get an error that reads."Microsoft Access was unable to create the .accde, .mde, or .ade file.This error is usually associated with compiling a large database into an MDE file.* Because of the method used to compile the database, a considerable number of TableID references are created for each table.* The Access database engine can only create a maximum of 2048 open TableIDs at one time.* Exporting a database as an MDE potentially can exceed this limit if the database has a large number of objects (table, macro, form, report, etc).
There is no accurate method to estimate the number of TableIDs the Access database engine uses during the process of compiling a database as an MDE.* However, each VBA module and each form uses one TableID, as a result, if the database has 500 forms, and each form's HasModule property is set to Yes, as many as 1,000 TableIDs are used."
I have created an access 07 database and split it to a back-end and a front-end with linked tables.
I wish to deploy it an a network of 4 computers, 3 of which are running on XP. The back-end will be on a computer running on XP. Now, from the instructions I have come across online, the Back-end has to be located on a folder where all users have Red and Write rights!!! And I am thinking, if the users on this network can actually see the back-end since it is on a shared folder where they have all the rights, then does that not compromise the security?
Is there a way of linking to the back-end on a network WITHOUT the users being able to access the back-end?
Is there away in which I can protect an access 2007 database modification with a password.I'm doing this because I would like to prevent my client from modifying or having acces to the database's back end system (db), I would just like him to use forms and nothing else.
We have an access database stored in a shared location. One of the tables in the database is used to record transactions made in an excel spreadsheet-this is done programatically using VBA and SQL.
So here is my silly question; If users don't have access installed locally will the code be able to write to the shared access database?
I wanted to send a message to the person who created this sample database with a modification query but I don't have enough posts to do this, so my message would not send.
The below sample database called Sample - Use Hidden Form to Log Users ,URL...
I would like to add to my database. Any way to modify the form/code so that I can log more than one form? I have 5 forms that I would like to log user in and out of but I dont know how to adapt this to do that?
I have an Access database which has a linked table to a CSV file.Only one user can use this part of the database that links to the CSV - for other users we get the error 3051 - opened exclusively by another user. How can the csv file be a linked table with multiple users ? The query itself is set to no locks.
I have included some code to disable the access PassKey (holding shift down as you open the database so that the database window appears). It is password protected and it works pretty well for normal users.
However, I have realised that even in this restricted mode you can go to File-Options-Current database and enable Access Keys. This then lets you open the database window by pressing F12.
My question is, is there a way to absolutely stop anyone from ever viewing the database window at all? All my code is password protected, but I still don't want an ICT person fiddling with my tables and queries!
I am using Access 2007. My boss has given me a project to create a tool for our team. I'm done with most part of the project, but for the last part I want editing and updating of database restricted to a few members of our team. However others can access the database and run queries etc. through buttons on a form.
I went about creating a login form for users to get access to the database and in turn created a table with fields UserID, UserName, UserPW and a yes/no field titled IsAdmin. For those who would be limited access would log in as 'Other' user and same as password. I am then using the code to determine if the user should be treated as admin or not by looking up the IsAdmin field in the table. Following is what I have so far, but it needs correction some places and I can't figure where:
Private Sub cmdLogin_Click() Dim xxAdmin As String 'Check to see if data is entered into the UserName combo box If IsNull(Me.cboUser) Or Me.cboUser = "" Then MsgBox "You must enter a User Name.", vbOKOnly, "Required Data"
I have a form that I've created to allow users to do a ad-hoc query on data in a table. Most of the fields are setup as
Code: Like [Forms]![Unusual Login Research]![CustomerName] & "*"
where I have a drop-down box with options for: >, <, >=, <= and between. I've tried a bunch of iterations of the same criteria and keep getting the error above. Just as a test, i was trying to at least get the between option to work with the following:
I've prepared a front end database with forms that allow data to be keyed into linked tables to my main databse.
However, currently the front end database only allows 1 user to do it at 1 time and when another user tries to open the file, an error "The Database Has Been Placed in a State by User on Machine That Prevents It From Being Opened or Locked'
Is there anyway to allow multiple users to use the front end database at the same time?
If I need to take the backend of my database offline for changes, what's the best/easiest way to inform the users? Is there some code I can drop into the front end? I'm thinking a "on database open, if [available] in tblClose equals no, then open frmDatabaseOffLine". But I don't know a) if that's possible or b) how to program it.
I have a simple access database that 26 clerks in my office use to enter their weekly tasks. The database is split into a front end and back end, with the back end stored on a shared drive that we all have access to. We have been testing the database for 3 weeks with 5 clerks and no issues. This week is the first week that all 26 have used it, and immediately we encountered a problem.
I think the problem is happening because one of the tables in the database is linked to an excel spreadsheet. When multiple users try to use a dropbox that is linked to this table simultaneously they get an error message. I saved the excel file as a shared file, but this did not correct the problem.
I made a copy of the database before I split it. I know I can fix this if I import the excel spreadsheet into a copy of the database, link this table to the dropboxes, split it again, and redistribute it.
would like to leave the front ends linked to this spreadsheet, because we update it regularly. If not, we will have to have somebody update that particular table in the database intermittently.
I have two versions of the switchboard items table. (A2003 switchboard). I have a login form, and I want to be able to change the switchboard items for different users
so I have code that does this
close the switchboard, copy the new switchboard items table reopen the switchboard
And every time, it says it cannot copy the table because the switchboard items table is in use. The code in the switchboard opens recordsets, and I have quadruple checked that they are closing correctly, after use. The switchboard itself is bound to the switchboard items table
I have just tried something different which is to manually close the switchboard - and then I CAN copy the tables.
Might the code be atomic in some way. The switchboard does not release the locks until the code completes?
I thought about it, and got round it now, by just copying the data from the new table to the master table, rather than trying to copy tables, but I am still curious.
My database is slowly coming together. For the final part of this phase i would like to create a shortcut on each users desktop which runs a summary report of information within my database.
I have criteria set so upon opening the report the user is asked for which address they wish to see information from which works great. But I do not want users to have access to the database, I just want them to be able to click a shortcut, be asked what address they are looking for and for the report to ping up in a 'Print Preview' type layout so information can be seen and displayed but not altered. All users have the access program.
I have a multiuser data entry form which on using somtimes gets inactive, means the button stop working and we have to close the form and open again to avoid.
