Hello everyone
I have developed an application in VB.Net and Access 2007 where I am saving ,editing,searching, updating and reporting records from the database and everything is working fine except:
1. There are two access files one in the project folder (myprojectname\dbname) and one in the (myprojectname\bin\debug\dbname) and when i save a record it is being saved but in the (myprojectname\bin\debug\dbname) database and not in (myprojectname\dbname) database which creates a problem when i run the project again the record is nowhere now.
I use the following code for connectionstring

<br />
Imports System.Data.OleDb<br />
Module connection<br />
    Public Con As OleDbConnection = New OleDbConnection("Provider=Microsoft.Ace.OLEDB.12.0;Data Source=" & Application.StartupPath & "\mydb.accdb")<br />
   <br />
End Module<br />

I also tried

<br />
    Public Con As OleDbConnection = New OleDbConnection("Provider=Microsoft.Ace.OLEDB.12.0;Data Source=|DataDirectory|\mydb.accdb;")<br />

but all in vain.
Now, i request you that please help me in the correct way of dealing with access 2007 database in VB.Net
Note: mydb.aacdb is also in my solution explorer.

Thank you

Solution 1

Start off by not storing your DB in either location. It's a poor idea, as it will give huge problems in production - the application will be installed in the "Program Files" folder which is write protected for security.

Instead, consider using a "safer" place: Where should I store my data?[^] - it's in C#, but it's pretty much the same in VB.

Sir could not get it. Is there some simple way. Or some sample code for VB.net.

Every time you compile your project the database file in the project folder is copied to the target bin folder when you run the app. This operation overwrites the file database you modified the last time you ran the app.

Don't keep your database file as part of the project. Store the database in a place that is accessible to all users on the machine. Look at the Environment.GetFolderPath[^] method and the the CommonApplicationData[^] folder.
