WIndows 7 Won't Run .NET MS Access Database Connection Program, But XP Mode Does?
Mar 16, 2010
I have written a simple VB.NET program that connects to a MS Access Database. This program runs in Windows 7 XP Mode, but does not run properly in straight Windows 7. Somehow, the Windows 7 does not connect properly or read the MS Access database data properly with the DataAdapter.Fill method. I have dual monitors, so I can run the identical program side by side (one in Windows 7 and the other in XP Mode) - one works and the other doesn't (it doesn't crash, it just get "nothing" from the database when accessing - acts like it's not connected). Has anyone else run into this, or similar, problem with VB.NET and MS Access connectivity?

We have developed a 'deployment tool' (say program A) which need to modify system registry, etc info which requires admin rights. This program will be triggered by another program (say program B).
Question, when B call A, how can B initiate A with admin rights? is there any command like A.exe /runas admin or any other way to achieve this. Please note that both programs are developed using VB6.

My Ms-Access .mdb file is on my website. It is in the App_Data Folder
The current connection string is:
OleDbDataAdapter Da = new OleDbDataAdapter("Select * from SerialNo",
new OleDbConnection(@"provider=microsoft.jet.oledb.4.0;
data source=ftp://ftp.WebsiteName.com/App_Data/SerialNo.mdb"));
Where am I making a mistake in above connection string?

I created a connection to a Microsoft Access database by using the wizard. Now in the server connections I see my data connection to the db. I'm trying to create a method to compact the database, so I used JRO to do it. To do it however, an exclusive access is required, and when I try to call the method I get an exception.

My query is not the straightforward connection to MS Access.I am using a third application that places all data in an Access database BUT recently they changed the database so that it doesn't end in '.mdb', instead in another suffix: '.accdb'.The database is still an Access database but I cannot connect to it using the connection strings:[code]Previously I was able to use the second connection when the database name ended in '.mdb' (Database Name.mdb).

I'm writing a Windows form application in VS 2008. In the application I need to move among several SQL express databases (.mdf). I'm using the following commands to change the connection:
Me.MyTableAdapter.Connection.Close()
Me. MyTableAdapter.Connection.ConnectionString = "NewString"
Me. MyTableAdapter.Connection.Open()
I can see the form is showing data from the 2nd database. However, When I tried copying the 1st database (for a Save as function I'd like to implement), I got a system error saying "Cannot copy MdfFile: It is being used by another person or program.". Actually, I found all the visited databases were "being used" untill I closed my application. How do I break the connection completely?

I will be developing a program using visual studio 2008 with ms access 2007 as my database. What I only use is this type of connection string: "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:mydatabase.mdb;Jet OLEDB:System Database=system.mdw;" but i was asked if it is possible to put the database in sharepoint and I haven't even tried it before. The case is like this, the program that i will do would be installed on some computer units of different branches of the company then the database should be accessible through sharepoint so that every users can access the most updated database.

I am developing an application on VB.NET 2010, I am planning to make an online activation system, the idea behind is that Whenever someone installs my application, the application presents user an activation form, user will be entering product key, name and email address, and then system will establish a connection to a database which contains all the keys on WEB. So how should I make an efficient program to get rid of that.
