    <p>I apologize if my question is simple, but I have done a lot of looking on the Internet and I am having trouble finding a solution.</p> <p>I have a database connected to Visual Studio where I used the "Connect to Database..." wizard to establish the connection. In the Server Explorer in Visual Studio, I see I have a Data Connection called "newreptDBtest.accdb", and a Server named Mandrew.</p> <p>Basically I would like to execute SQL statements on this database when clicking a button. So I have a button on a form, and it has the following code:</p> <pre><code>Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim sqlconn As New SqlConnection sqlconn.ConnectionString = "server=Mandrew;Initial Catalog=newreptDBtest.accdb" Try sqlconn.Open() Catch ex As Exception MessageBox.Show("Error on connection") End Try If sqlconn.State = 1 Then MessageBox.Show("Success!") End If End Sub </code></pre> <p>In General Declarations, I have:</p> <pre><code>Imports System.Data.SqlClient </code></pre> <p>Perhaps because it's not a SQL database? I'm not sure. Either way, I have not been able to achieve the "Success!" from the MessageBox. Once I've gotten that, I'm sure I can figure out how to create SQL statements to return certain rows or single pieces of information.</p> <p>In the newreptDBtest, the table I'd like to be executing queries on is called newrept, and the connection string to the database is: </p> <pre><code>"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\Andrew\Documents\newreptDBtest.accdb" </code></pre> <p>tl;dr:</p> <p>How do I use an object (such as a button) to execute SQL queries on a table inside a database already connected to my project? </p> <p>Thanks in advance, SuperXero</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
