Using an application written in vb.net and using qbfc8 to connect into QB Enterprise 11. I am making a simple call to the company file to open and then close a connection. This should result in the QB application popping up a message asking if this application is allowed to have access to this file and then I am able to assign it to a specific user to sign in as.
This all works great except on this one particular server where I have yet to get it to ever popup the application request to access QBs. An error is always returned saying, "A QuickBooks company data file is already open and it is different from the one requested." with an error code of -2147220470.
I am using these instructions to access the file: http://support.quickbooks.intuit.com/support/pages/inproducthelp/Core/QB2K12/ContentPackage/Verticals/Retail/rr_sdkapp_access_preferences.html
Also I am in single-user mode while doing this: http://support.quickbooks.intuit.com/support/articles/SLN41168
On this server there are a few QB files but none of them should be being used right now, but is there a way to find out if there are any QB files being accessed on the server that is keeping the popup from appearing?
Thanks a ton!
There is not a direct way that I know of to see what company file is currently open (if any) without calling BeginSession and checking for errors. If you supply a company file name and a different company is open, you will get the "A QuickBooks company data file is already open and it is different from the one requested." error.
If you omit the company name when you call BeginSession, QuickBooks will use whatever company file is open and present the prompt(assuming the rights have not already been granted). However, if there is not a company file open, then you get an error "Could not start QuickBooks." (if QuickBooks isn't running at all), or "If the QuickBooks company data file is not open, a call to the "BeginSession" method must include the name of the data file." error if QuickBooks is open, but has no company file open.
Most programs will save the company file that they have been linked to, so they will pass the file name in their BeginSession call, and then check for the "A QuickBooks company data file is already open and it is different from the one requested." error and present the information in a clean way to the customer. For example, the QuickBooks POS software will prompt the customer if they want to continue using the old file that was setup previously, or if they want to link to the file that is currently open.
I resolved this by installing the application connecting to the QB file on the same server. Then (this is the important part of the recipe) I changed the path from the defaulted UNC path to a local path and it magically worked. (I hate magic! If someone could explain why this happens then that would be great.)
Now that I have the integrated application authorization for this app added into the QB file I am now able to access it from other work stations using the same app and using a UNC path to point to the file.

i have a shared access application, i created an accde file for 32-bit machine, when user open the application he/she getting a security warning
is there any way to disable this message from appearing to the users
thank you
You have to set their computer to be a trusted source. In order to get around this issue, you will need to create a Digital Certificate. Digital Certificates are good only on the computer they are created on, so if this database will be used on multiple computers then each one will have to create a Digital Certificate.
To do this, you will need to perform the following tasks:
Click on Start -> All Programs -> Microsoft Office -> Microsoft
Office Tools -> Digital Certificate For VBA Projects (If you don’t
have this, you will need to contact your IT Dept.)
Enter a Certificate Name. Make it obvious like MyProgramName and Click OK
Open the Access database which contains the security warning you want to bypass
Go into the Design View of any Module
Click on Tools -> Digital Signature
Choose your Digital Certificate you created in Step 2
Save and close the database
Re-Open the database. You will now be prompted with a different Security Warning that states the file has been digitally signed.
Check off the “Always trust files from this publisher…” box and click the Open button
All subsequent times you enter this database, you will not be prompted with a security warning.
Note - I wrote the above for our company based on Office 2003. If you're using a more recent version, the instructions may vary somewhat.
other way is following:
click on file and then options
click on trust center and then trust center settings on the right
then click on trusted locations and add new location
browse for the location and save.
that's it.. done.. now no more warnings..
That is a standard warning to indicate the file you are opening has web links and macros.
If you trust the file, just say OK or “Allow”
You can control if this message is displayed: Office button > Excel Options button > Trust Center > Trust Center Settings button (I have no idea why they have this extra button, DUMB DESIGN! )

I have an Access database that processes other Access databases. I get OP's error when connecting to one of the other Access databases. To fix the issues, I opened the other Access database and clicked Enabled Content. Then, the Access database is trusted and OP's error doesn't occur when connecting to that Access database from another Access database.
You can create a registry key that will add the directory as a trusted location and will not show the warning anymore. What's nice about this method is that you can easily automate this to happen on the computers where you deploy your app. See method #2 or #3 in this blog: http://www.accessrepairnrecovery.com/blog/fix-microsoft-access-security-notice
And in case the blogs ever gets removed, here is the important bits:
[HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Access\Security\Trusted Locations\Location20] “Path”=”C:\Database\”
“Description”=”My Database location”
Explanation about the key:
– The number “14.0” is the version of MS Office. You can change the numbers that represent the version you are executing.
– The “Location20” is a unique name that you assign. 20 can be any number that is not previously used. Other programs include default MS Access wizards, already have used other numbers. But if you want to make more than one path as trusted location, then each location must end up with different number.
– The “C:\Database\” is the physical path that you want to set to be as Trusted Location. You can place any path that you choose here.
By copy and pasting the above coding into a text file and save it with a name such as RemoveSecurityWarning.reg, you can then run the file into your PC’s registry just by making double click on the file.
The best way is to add the location of the document or the document itself to the Trusted Locations in Registry (if you use only Access runtime on client machines, there is no way to add it through the Office application, like you would do in Excel).
Here is the answer:
Adding Trusted Location to Access Run Time
You would need to create a new Location key and add the necessary Path (and Description) strings inside with the appropriate location of your file. This way the nag dialog will be gone and you won't need to worry about certificates.
Shared may mean it is located on a network share. It is not advisable to add a network location to the Trusted locations and you would need to set the additional flag AllowNetworkLocations to 1. I would advise you to copy the Access modules to the user computers, which would also make things better with the speed I believe.
If anybody else have this problem, it happened to me, with a shared file on a network environment, and the simplest solution was to install Microsoft Office service pack 2, even better is having automatic updates for Office turned on. You can find it here.
I have program which get the word file from server and after editing it saved back to server . It was working and i was able to save files back to server but suddenly files are opening in Readonly mode . I have searched alot on google and have tried all options but it seems not working.Any ideas clues ??
If the file displays as read only in Word that means word thinks the file is readonly, which means its seen something to make it think that. Since word does not integrate with access control methods over webdav, that means it can only be that word has determined that the server does not support required operations for writing. This can be:
does not support uploading (ie PUT). Webdav reports this in the OPTIONS request, so please check for that
does not support locking (ie LOCK)
does support locking, and the file is locked. But this usually gives the user a specific warning
Locking comes into play in different ways depending on how you're connecting to the server (on windows you can either use a mapped drive or a network location), and the means of opening (either clicking a link in a web page which uses the sharepoint dll, or opening directly from a mapped drive, or opening from the file open dialog in MS office), and of course the application doing the opening (ie MS Office, Open Office, etc)
Depending on what combination of the above you're using locking might or might not be required to edit.
Webdav indicates locking support in the following ways
- the supported levels header
- MS-Author-VIA header, which should return "webdav"
- the presence of LOCK in the OPTIONS response.
So you might need to check for the presense of those, probably by using wireshark or similar.
I am extremely new to Ms-Access. I have a central back end access database in server computer. And all the users have the front end user interface installed on their system.
Now, whenever I make any changes to the interface in my local, i need to re-install the updated interface on each of their system. Is their any way that i can do so that i will make the changes only on my local and it will be automatically reflected on all the users' systems.
Thank you.
Ok there are a couple of options that you can do to either fully or paritally automate this process.
Partial Automation
If you don't have a lot of users and you don't want to do a great deal of coding you can write a simple batchfile or vbs file which you set up on the users desktop as an icon. Batch file code would show the following type of information.
#Echo Off
REM Copy your file from server location to local user machine
xcopy "F:\ServerDirectory\databasename.mdb" "C:\ClientDirectory\databasename.mdb" /E /Y /R
Set this up on the users machine as an icon and whenever you want them to update their front end ask them to double click the icon. This will overwrite their client with whatever you place in the location on the server. It is advisable to create all table links to the database back end having UNC paths as well.
I have used this successfully for various applications - I make changes to the front end place in appropriate location on the server and then do a quick e-mail to people just to ask them to double click the bat file icon.
Full Automation
Programmatically set version control up using visual basic so the client checks version number of the client against a server number and if the client is not the latest will download a new version.
This is more involved and full instructions are available here.
Front End Auto Update
When you deploy an MS Access solutions like this, you need to decide whether to share the client MDB file between all users, or distribute copies to each user. It sounds like you have taken the second option. Each choice has merits and disadvantages. If you stay with the current approach, you might look at a scripting option to deploy updated client MDB files between users.
Is it possible to retrieve the name (or IP address, whichever) of a computer that is accessing a file on my shared folders via workgroup? If so, what would I need to retrieve it? Filename? File directory?
I am using vb.net 2005.
The short answer is NO.
But, if you are on the computer that has the share, you can go into Administrative Tools>>Computer Management>>System Tools>>Shared Folders>>Open Files and and you might get some information about what files and who. But this is not reliable because only certain files apply locking and they will only show up here if locked from another computer. Too often windows will tell you the file is locked but you will not see the information in here.
Ok, our current problem is the classical "trying to allow multiple users access onto one fe file (this is in runtime currently)" - This cannot be handled (at least in AC2007) and is best solved by installing a FE on each computer that is using it.
This poses another problem for us, we have many employees who we want to be able to have access to it, yet the program probably doesn't warrent our techs to push out updates of this file to each computer with their "patches" (plus there may be added costs to doing such for us).
We would really prefer the ability for users to open a link from our internal portal to the file as can be currently achieved. We are mulling over the possibility of pushing out 4 or 5 copies of the FE application on a shared folder and creating an Access program that would essentially check to see if a FE app is open say FE1 and if so it would open FE2 (and so on) then close the sharepoint linked database that did the checking so a new user could open that. This would allow multiple users access to the same BE information using the same FE program.... would this work? Any ideas of how to go about it?
Yes it works, the idea is to create a function that checks for the open file, if it finds its open it replies with an error, on the error you can move to the following database. Here is a sample code:
Option Explicit
Function FileLocked(strFileName As String) As Boolean
On Error Resume Next
Open strFileName For Binary Access Read Write Lock Read Write As #1
Close #1
If Err.Number = 0 Then
Application.FollowHyperlink "c:\MasterMAX.accdr"
DoCmd.CloseDatabase
End If
If Err.Number <> 0 Then
Application.FollowHyperlink "c:\MasterMAX2.accdr"
End If
End Function
Disclaimer: I don't know anything about SharePoint, so I can't say if my proposed solution is still viable when SharePoint is involved.
If your problem is just how to distribute the file to all machines, why don't you let your users start a batch file that copies the Access frontend from a network share to each machine and starts it?
We are doing something similar at work (without SharePoint, though), and I described our setup here:
How to automatically update MS-Access 2007 application
We have put the batch file on a network share as well. The users have just shortcuts on their desktops to the batch file on the network share, so it's easy to update the batch file as well.
Maybe you can do something similar (let the users run the batch file from SharePoint, which copies and starts the Access frontend).
