I would like to open a access database using VB.NET. However i want to be able to connect to a Access database at runtime and have this appear in the datagrid. how do you do this?

I would also like to create a database using VB.Net and have fields weight,comment inserted into it, and then for this to appear in the same datagrid. the option to save this new database would be needed.

Any help wil appreciated

Dim con As New SqlConnection("Data Source=ABC-17372608800\SQLEXPRESS;Database=sonia;integrated Security=true")
Dim da As SqlDataAdapter
Dim ds As New DataSet

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

da.Fill(ds, "student")
DataGridView1.DataSource = ds.Tables("student")

Hi, while you did not specify which version of Microsoft Access, you probably using pre 2007 version. There is a website http://www.connectionstrings.com that has examples for how to connect to pretty much anything in existance.

Here is the link for the Access connection string: http://www.connectionstrings.com/?carrier=access

Hopefully, you are using Visual Studio 2005, so all you need to do is drop a OpenFileDialog component on a form, otherwise, if you are using Visual Studio 2003, you may have to build the UI yourself. Once your user locates the Access file, simply update the connectection string.

Hope this helps,

Johnny
