Examples
The following example creates a SqlCeConnection, opens it, executes a query, and then closes the connection.
Dim conn As SqlCeConnection = Nothing
Try
conn = New SqlCeConnection("Data Source = MyDatabase.sdf; Password ='<pwd>'")
conn.Open()
Dim cmd As SqlCeCommand = conn.CreateCommand()
cmd.CommandText = "INSERT INTO Customers ([Customer ID], [Company Name]) Values('NWIND', 'Northwind Traders')"
cmd.ExecuteNonQuery()
Finally
conn.Close()
End Try
SqlCeConnection conn = null;
try
{
conn = new SqlCeConnection("Data Source = MyDatabase.sdf; Password ='<pwd>'");
conn.Open();
SqlCeCommand cmd = conn.CreateCommand();
cmd.CommandText = "INSERT INTO Customers ([Customer ID], [Company Name]) Values('NWIND', 'Northwind Traders')";
cmd.ExecuteNonQuery();
}
finally
{
conn.Close();
}
