i want to know simple code that can be using for connecting to access database in vb.net so that it will work on all client systems after deployment.here is my code

VB

Dim strConnection As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\USER\Documents\STOCK1.mdb"
 Dim cn As OleDb.OleDbConnection = New OleDb.OleDbConnection(strConnection)
 cn.Open()

The name of my system is USER and the code is working well on it.But on the client system that the name is not USER, it will complain of not finding path of the database. The application is a window based application written in vb.net
Thanks

Solution 1

You need an install script that modifies the string so that it refers to the correct location. Better still use a generic location that is not tied to a user's actual name. See Where should I store my data?[^].

"The name of my system is USER and the code is working well on it.But on the client system that the name is not USER"
What more can I say? It is obvious what the issue is. You need to change the string "USER" when you install on any other system. Or do what I suggested and use the advice in OriginalGriff's article.

Solution 2

You could just use the Public Documents folder. Another option is to use environment variables, but you'll need to change your installer/deployment tool as well, unless you create your database on the fly.
