Question

i am building a database application in vb.net and i started by adding a data source from the DATA in the toolbar. my connection is good and it shows all my tables in the data source panel.

i also see new classes related to my database, like

sakilaDataSet
sakilaDataSet.customerDataTable

…
and so on.

how do i query and use these ? i googled a lot and i am not able to get this.

Dim cust As sakilaDataSet.customerDataTable = New sakilaDataSet.customerDataTable
        Dim row() As System.Data.DataRow = cust.Select("customer_id=5")
        MsgBox(row.Count)

My last try was with the above code, but the row.count always turns out to be zero.

Answer 1

What i wanted to achieve was not to use connection strings again. After adding the data source in VB.net, it makes Data Classes and Adapters, which i can use directly to access the database, as follows :

Dim staff As sakilaDataSet.customerDataTable = New sakilaDataSetTableAdapters.customerTableAdapter().GetData
Dim rows() As sakilaDataSet.customerRow = staff.Select("email='" + email.Text + "'")
