I'm using old DAO 3.6 to connect Access database (with mde extension). App works fine on XP and on Win7/Vista when UAC is low/disabled. But when UAC is on I get following error: The Microsoft Jet database engine cannot open the file 'C:ProgramDatacompanydb.mde'. It is already opened exclusively by another user, or you need permission to view its data. [code]

I have a WinForms application that I have taken over support for and it was build using Visual Studio 2005 with VB.Net. The application makes use of an Access database. It runs fine when it is installed as a standalone application, but the install cd for the application also allows for a network install and this is where I am currently encountering issues.
To test the network install I created a folder on my server (Windows Server 2003 SP2) and copied the Access database to this folder. I created a share for this folder and gave everyone full permissions to the share. Then on the workstation I installed the application and gave the path to the database as follows:
\myservermysharemydb.mdb
(The install steps here are as per the instructions given on the installation cd)The workstation that I installed it on is Windows 7 Ultimate. When I run the application, I get the error message given in the title when the application tries to read the database file. I have confirmed that I am able to write to the shared folder on the server, so I don't think this is a permissions issue. Also, the database file is not in use at all, so it is definitely not opened exclusively.
UPDATE:I have tested the workstation installation on a computer with a fresh install of Windows XP SP3 and it is able to access the database file without a problem. So it seems that this error that I am getting is somehow specific to Windows 7. Is there maybe a known issue with Oledb drivers on Windows 7? My version of Windows 7, btw is 32 bit.

View 3 RepliesI am developing a software that connects to a database and manipulates product and user data. It works on my computer but it will have to be used by many computers maybe even world wide (who will access the same database) so I have no idea what kind of systems people will have. I still don't know how to ensure that they will be able to connect to the database for I have already had problems in Windows 7 computers which don't have jet oledb.4.0
I am a bit lost here because I don't know if I should first try to do a connect, or if I should first look for a jet oledb engine on the computer where the software is installed. And in case they don't have it installed should I prompt them to install it before running the program further? Or should I pack the engine along with my program? What is the line of thought here to make the program run on (almost) any machine?
I'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ConnString ="Driver={Microsoft Access Driver (*.mdb)};Dbq=" & Application.StartupPath & "\CITSDB.mdb;Uid=Admin;Pwd=123;"
But, when I changed the mbd to accdb:
ConnString ="Driver={Microsoft Access Driver (*.accdb)};Dbq=" & Application.StartupPath & "\CITSDB.accdb;Uid=Admin;Pwd=123;"
It resulted in errors:
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'.
ERROR[IM006][Microsoft][ODBC Driver Manager]SQLSetConnetAttr failed
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'
And then it shows me that my code for
If dsLogin.Tables(0).Rows.Count = 1 Then
IndexOutOfRangeException was unhandled
Cannot find table 0
I knew it must be the driver but I don't know what accdb driver I can use for the connstring.
just if you are using Microsoft Access Data Connectivity Components 2010 in your application to read data from mdb access files, you might get unexpected exceptions and your application will crash!To reproduce this behavior the best way is to run my sample application which will allow you to see the bug directly in no time.This behavior may occur at any time, any where, but I found if you use Application.DoEvents, you increase the chance to run your application to crash.To reproduce ::
1. You should not have any Office version installed on your system (I am using Windows 7 x64).
2. install the Microsoft Access Database Engine 2010 x86 (or x64 and you'll have to set your project to x64).[URL]
3. Download and run my sample application in VB.NT 2010, and press the button, you will get it [URL]Where is Microsoft going, do you think?Should I hope to receive an official response?
