    <p>Both SqlConnection and SqlCEConnection extend System.Data.Common.DbConnection, so declare "blah" as DbConnection, and you will able to use the same methods and properties.</p> <p>To actually create the correct connection type, use the System.Data.Common.DbProviderFactories and System.Data.Common.DbProviderFactory classes. For example:</p> <pre><code>DbProviderFactory providerFactory = DbProviderFactories.GetFactory("The Provider Name"); using (DbConnection connection = providerFactory.CreateConnection()) { connection.ConnectionString = "The Connection String"; connection.Open(); // Use the "connection" object here } </code></pre> <p>For "The Provider Name", you would put in either "System.Data.SqlClient" or "System.Data.SqlServerCe" depending on the database type. And then for "The Connection String", you would put in the correct connection string for the provider type.</p> <p><strong>EDIT:</strong> this technique works well with your App.config file and the System.Configuration.ConfigurationManager class. For example, if your App.config file looks like this:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;configuration&gt; &lt;connectionStrings&gt; &lt;add name="TheConnectionString" providerName="System.Data.SqlClient" connectionString="Blah Blah Blah" /&gt; &lt;/connectionStrings&gt; &lt;/configuration&gt; </code></pre> <p>Then you can access these configuration settings like this:</p> <pre><code>DbProviderFactory providerFactory = DbProviderFactories.GetFactory(ConfigurationManager.ConnectionStrings["TheConnectionString"].ProviderName); using (DbConnection connection = providerFactory.CreateConnection()) { connection.ConnectionString = ConfigurationManager.ConnectionStrings["TheConnectionString"].ConnectionString; connection.Open(); // Use the "connection" object here } </code></pre>

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.
