General :: Allow Users To Access A Database
Oct 27, 2012
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 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"
[Code] ....

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?

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'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 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.

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'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 was wondering if it was possible to be able to make changes to a form whilst others are accessing different forms.
At the moment, if i am editing the database any user trying to access the database gets a error warning them, they the database is in admin.
But if another user is in the database while i am trying to change a form / report, i am unable to save.
I no the simple way to do this would be to do changes whilst no-one is in. Its just some minor tweeks need doing during the day.

I have a split database consisting of an ACCDB backend helf on a shared drive, and a local ACCDR frontend distributed through email. I recently distributed a copy of the ACCDR to a user, and she says that the main menu opens fine, but when she clicks a button to open a form, the form opens but is completely blank. I've googled some possible causes for this (e.g. on Allen Brown's website) and none seem to be relevant, or would explain why this started happening all of a sudden. I can't reproduce this bug at all.

I am trying to set up a simple database to record vehicles that access our parking at work..Our Car park requires users to have permits to park here but we are continually getting vehicles that dont. We require a database that shows authorised cars and also ones that have been recorded and warned.
Each car will have 3 warnings (Green, Yellow and Red Card) once they get a red card their vehicle is clamped
the info we need is
Car Reg
Car Make
Car Model
Car Colour
Owners First Name
Owners Surname
Permit holder (Yes / No / Expired)
Permit Date issue DOES NOT APPEAR WITH "Permit No"
Permit Date Expiry (AUTOMATICALLY CALCULATED FOR 1YEAR) DOES NOT APPEAR WITH "Permit No"
Number Of Strikes
when the permit expiry date exceeds "TODAYS" date this shows up as out of date and the "PERMIT HOLDER" field automatically shows up as EXPIRED.

I have two separate database files, a front end with all my forms and a back end with all my tables. The backend is stored on a network drive, is there any way of being able to store the frontend on the drive with the backend? Users do not use the actual computer to store information or access files, everything is usually saved on the network drive. I have created a shortcut that launches the front end database in the read only kiosk mode.

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.

I've got a database in Access 2007 that keeps track of client data for work. It's been working fine for about a month, and suddenly today other users can't change any information because the records are suddenly locked when accessed from their accounts.
I've already checked that they can't update forms, tables, nothing.
I've checked the database properties, it defaults to shared with no locks.
I've checked the properties of my forms - no locks.
I've double checked the permissions to the folder that the database is in - no restrictions.
The database is split.

This morning I accidently ran the "User-Level security wizard" on a secure database that we use. I meant to add a member but clicked the wrong thing and followed suite by hitting "Finish" instead of cancel because I wasn't paying attention. Aside from creating a "Security.mdw" file which isn't being used at all, it also somehow managed to lock everyone but the administrator out.
I checked the Users/Groups and Permissions, they are all there and correct, nothing seems to have been changed at all but when anyone tries to log in now they get the following error:"You do not have the necessary permissions to use the '...mdb' object. Have your system administrator or the person who created this object establish the appropriate permissions for you."
I've read some posts with similarish issues that recommended recreating the .mdw file and importing the data over. The file is encrypted so I wasn't able to do that but I did try making a copy and renaming it then changing the path in the Access shortcut to the copy instead. What all files/settings handle this and if the Users/Groups show up correctly in the database, what could be preventing the users from getting in?

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?

Hi, I created a database where everybody should insert his holiday plans and absence of business. the Database is linked and opens automatically the form when you click on the link on the pdf. But know it is not possible anymore that more than one person opens the file to insert the data. The mistake is: Could not lock file!
What do I have to do that more people can use the database at the same time (not only read-only) Thank you for the help

Greetings. When I create an Access database on my company's "secure" server (through a PIX box), I get this message in a dialog box when I try to open the database again: "Open File - Security Warning. Do you want to open this file?" It then gives the file Name, Publisher (unknown publisher), Type (Microsoft Office Access Application), and From (the file path and name). The bottom of the dialog box has this message: "While files from the Internet can be useful, this file type can potentially harm your computer. If you do not trust the source, do not open this software." When I click on the "Open" command button, the file opens just fine.
There are a couple of things going on here:
1) When I open this same database or any other Access database on another of my company's servers that is not protected by a PIX box, I do not get this dialog box.
2) When two users try to access an MS Access database on the "secure" server, the first user will get in, but the second user will not. The second user will not get ANY warning messages -- nothing happens. This occurs if the second user tries to open the database by either double-clicking on a shortcut on the desktop or by double-clicking on the file name in Windows Explorer. Note that the second user CAN access the same file if s/he starts up MS Access from scratch, and then chooses FILE>OPEN from the main menu.
My goal is to be able to let multiple users access the MS Access databases on the secure server by either double-clicking on the shortcut icon or by double-clicking on the file name in Windows Explorer.
I thought perhaps that the "unknown publisher" issue might be part of the problem on the secure server. So I created a certificate using the utility "SELFCERT", went into the database, went into Visual Basic (Ctrl-G), went into TOOLS>DIGITAL SIGNATURE and assigned the digital signature, and re-saved the file. I then exited the file, went back in, and the dialog box still pops up saying the file's publisher is "unknown publisher"! If I go back into Visual Basic, the database is clearly marked as digitially signed by me. I don't know why the initial dialog box is still showing that the file is not digitally signed.
If anyone has any thoughts about these issues (multiple users not being able to access the same Access database, and why my file is saying it is still not digitally signed), I would appreciate your input. FYI, I am on a Windows XP workstation and our company users Windows Servers.
Thanks,
David
