Modules & VBA :: Identify Users With Database Open
May 1, 2014
I'm wondering if there's any way to find out who has a database open.
I've saved the file as an ACCDE for the users and kept the ACCDB file as my working file. Whenever I make changes to the db I need to save a new ACCDE file on top of the existing one. In order to do that, I need to ensure no one has the db open. Half the time I need to track down 1 of 15 people to find out who it is that has it open so I can kick them out and save.
I don't have any login features, but could use the POD # that each cubicle has associated to their computer if Access allows that...

I have two databases that have been split, and both back ends are in a shared folder on the server that only a few people have authorization to access. One of the front ends is accessed off another shared folder, and the other is saved to each person's desktop. They have been up and running for months, and I've had no problems with users not being able to access data from the back end.
The other day, I requested access to this protected folder for four people, which was granted. But, since the time it was granted, neither database will open unless the user has authorization to access the protected folder. They get an error that says the database is already opened exclusively or they don't have authorization to view its data.
I've created another test db and split it into the same folder, but my users are getting the same error.
Any help you can provide would be much appreciated.
Thank you,
Mike

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

We have a database that is split. Every user has their own front end (installed via a .bat file so that the users always have a local copy of the most recent version), linked to a shared back end on a server. This seems stable and functional for us so far.
However, because our users are geographically separated, I don't actually know how many folks are using the database. I know the folks who contact me, but everyone in our company could use it if they wanted to.
For requesting funding, guiding future development, etc., I need to get some metrics:
Total number of unique users
Avg uses per day
Total number of simultaneous users (daily, weekly, and monthly maxes and mins)
What is the best way to get this info? Write user info and a timestamp to a table each time a front end is launched? Are there tools for monitoring this sort of information?

I have designed a database which I intend to split for multi-users to access from one front end icon on a shared folder at work. I have designed a form bound to cmr record table and on it a subform to another table where cmrs activities will be saved. The form has buttons to and blank controls.
User can create a new activity entry by typing into the blank controls and pressing the save button which saves to the activity table. the edit button extracts a selected records details (selected on the subform) from the activity table and populates the blank field for a user to edit and then hit save to save changes. The delete button deletes a selected record from the activity table. I intend to have multi-users either accessing, viewing and a possibly editing the same customer at the same time. The simultaneous viewing is essential but the simultaneous editing, though not desired is inevitably going to occur.
What I would like to know is:
1. Can you lock an individual record in a table or does the whole table have to be locked. E.g If Colleague 1 is editing Cmr A's record in Table1 can he lock it so Colleague 2 can view and edit Cmr B's record in Table1
2.Can Colleague 1 access/read Cmr A's record in Table1 to retrieve details toe the form controls if Colleague 2 is viewing or editing Cmr A's record in Table1
3. If record lock is possible, how can I initiate it in my example code below.Edit activity record Code
Code:
Private Sub Edit_A_Click()
'Get Data to text box control
With Me.R_P_Data_P_Subfrm.Form
Me.txtrID = !rID
Me.txtrID.Tag = !rID
Me.txtrefNo = !refNo
Me.cmbrpc = !rPC
[code]....

I have a global function which I have hooked onto the onClick event of controls. Currently I am using commandButtons as my control of choice. In my function I can then reference Forms.ActiveControl which is no problem.
However, for lots of reasons I really need to use Image controls. Now, my problem. Image Controls have an Onclick Event, but they do not get focus so the Forms.ActiveControl will not work.
How can I identify the image control that has generated the click event if the control itself does not get focus and so cannot be referenced by ActiveControl? Working on a possibly work around, but could do with the best brains in Access on the case!

I have a button on my main db, that opens a second db using hte following code:
----------------------
'Dealing with external objects, use inline error trapping
On Error Resume Next
Dim appAccess As Object
Dim db As Database
Dim strAppPathName As String
Dim strAppName As String
Dim strTimesheetPathName As String
[Code] ....
This code works great to open the other db, and handles wheter the other db is already open or not, but I cant seem to pass the variable to the other db using the startup switch /cmd.
I suspect if I used the shell method it would pass the cmd , but I havnt found any way to test if the db is already open with the shell method.
How can I pass a variable to the other db when opening it using VBA?

I would like to be able to check if a db is open and if it is to prevent the user from proceeding.
I use the Access 2013 Runtime. I can check if a db is open by trying to open Exclusively, using something like
Code: [URL] ....
But if the db is already open Not exclusively and I try to open it exclusively it does not raise an error and it allows the user to open the db in Read Only mode.
I would like to be able to prevent this, because careless and/or inexperienced users may open several instances of the db.
Of course, if the db is already open exclusively it does not allow you to open it exclusively another time.

I have an Access DB with a form that allows the user to select a new backend database. I can connect to the backend and then .refreshlinks but nothing on the form is updated. I have tried requiring the form but that doesn't do anything. I've tried loads of other things, refresh, recalc etc., but nothing updates the open form.
The only way I have managed to get it to work is to close the form and reopen it, then it shows the data from the newly linked backend database.
While it works, it doesn't look good but also there seems to be some problem with it because eventually it reports an error saying "cannot open any more databases" and when clicking OK comes back with "An error occurred while sending data to the OLE server (the application used to create the object" and a whole bunch of other messages.
I think it might have something to do with the fact that the form has a number of MS graphs open on it, but I'm not sure. Also, I can't track down a particular line of VBA code which causes this error.
how to update a form after changing the backend database.

I have to create a database with more than ten thousand records. There is a field on which image by clicking the image to be displayed with the default program based on the image on which you clicked.
Code:
Private Sub Campo1_Click()
Dim L As Long
L = ShellExecute(0, "Open", """" & "C:UsersNickDesktopDocumentiPicturesDioDiego.jpg" & """", vbNullString, vbNullString, 1)
End Sub
When onClick event happens on the image is displayed the same image regardless of the record on which you clicked. How do I change the code to open the image of the field that was clicked?

I've created a database which works fine and i've tested it extensively on my machine. It is saved on a network drive which other users have access to. I've added a simple security log-in procedure (which I picked up from a sample posted on here) which only determines what buttons the different users can see on the switchboard which takes them to the different areas of the database. The problem I now have is some of the forms aren't opening.
Other Users who try and go into the forms that they have access to - even some of the generic ones cant open the actual forms as it crashes and comes up with the generic error message - "Microsoft Access has encountered a problem and needs to close".
I cant understand why this is happening. The security measures are only linked to the main switchboard and it works fine as it opens up all the other relevant switchboards as required. It's just certain forms on the other switchboards that refuse to open. I hope I have described my problem adequately and someone has encountered it somewhere or knows what I'm talking about and can help. Please let me know if you need further clarification.

Hi
I am looking for help related to the “You do not have exclusive access to the database at this time. If you proceed to make changes, you may not be able to save them later.” message when trying to change the design. I have done a lot of reading on this forum as well as googled the subject but have not found anything regarding my specific question. I find that there’s a whole lot of information regarding workgroup security and how to set up and troubleshoot. However, my needs are a bit more simple – I think :) We have a database that is shared among 5-6 users during a couple months out of the year. There are no log-on id’s required and everyone just opens the file and works as needed. Everything works fine; we have no problems with users changing or doing more than they are supposed to. Therefore, I don’t want to break anything by complicating matters…it works and we’re happy with it. The only annoyance is that during these couple months, someone has to make occasional changes to the database in design mode. Of course, we need everyone else out of the database so he can have exclusive access. This entails calling and/or running around asking those people to close the file and sometimes physically checking computers left unattended with the file open. So my question is: Is there any way to find out what users or workstations have the file open? This would make it so much simpler. All the users are on a Windows Server 2003 network and the files reside on a server. Perhaps this is more of a Windows question; I couldn’t think where else to post it! If anyone could point me in the right direction, I would really appreciate it.
Thanks!

I want to make a simple FrontEnd for my database for users to open reports to print them. I don't want them to mess with the linked tables or queries feeding into those reports. I want the front end to display a list of every report in the database that they can load up and use.

MS Access 2013: I have two database tables as below:
tbl1_MainDB --- It has a field named as "City" where I get huge data for some city names. Sometimes This field may have some unknown/new names which are not listed in our 2nd table ("tbl2_RefrDB")
tbl2_RefrDB --- It's a reference table which has raw names for cities, and then standard names of their city and state in another fields.
Target --- I want to create a VBA prorgram (Sql query) which can look from tbl1_MainDB.[City] to tbl2_RefrDB.[Raw_City] field, and if found then pick the "Standard_State" and "Standard_City" record values from there, and update into the 1st table "tbl1_MainDB".
...if not found in "tbl2_RefrDB" table, then user can be informed & ask for updating the new/unmatched city record as a new record in this table.
Attached sample database for more details.

I would really like to have a better understanding of the secrurity that comes with access. I would like my DAP to be able to log in with the previleges given for each user. I would also like these previledges to work when someones opens the database with access, however, whenever I set the secureity stuff, copy the database to the fileserver, I can then open it with another computer without any problems. Why is this? Thanks guys, I'n new here.

Is there a way in Access to logout users from a database in order to make updates without having to setup a FE/BE situation? My company is using Novell Client 4.90.0.0 SP1a. I have read some logs where you choose File --> Open (exclusive), but I do not have that option (using Access 2000). Any other thoughts?

Is Access set up to handle multiple people entering data into the same table?
We are processing returned mail and enter all the bad addresses into an Access table. The data is simply entered into the bare table. Can two people be doing this at once without the risk of compromising the data?
