Body
I am trying to Update a table in an access database from C#. It is a .mdb type database. here is the connection string I am using. <code>public MainWindow() {</code> <pre><code>InitializeComponent(); OleDbConnection cn= new OleDbConnection();} cn.ConnectionString=@"Provider=Microsoft.Jet.OLEDB.4.0;DataSource=" + "C:\Users\Angela\Documents\Visual Studio 2010\Projects\Havnefoged11.mdb;" + "User Id=;Password=;"; cn.Open(); Application.Current.Properties["DBConnection"] = cn; </code></pre> The file is in the correct folder C:\Users\Angela\Documents\Visual Studio 2010\Projects <pre><code> private void button1_Click_1(object sender, RoutedEventArgs e) { OleDbConnection conn = (OleDbConnection)Application.Current.Properties["DBConnection"]; //Below are the values i want to put into the database String dybde = Dybde.Text; String bredde = Bredde.Text; String plads = PladsNummer.Text; String StrSQL = "INSERT INTO Bådpladser (Plads_nummer,Bredde,Dybde) VALUES (´´"+ plads + "´,´" + bredde + "´," + dybde+");"; OleDbCommand InsertCommand = new OleDbCommand(StrSQL, conn); InsertCommand.ExecuteNonQuery(); } </code></pre> I then get the error OleDBException was unhandled NO value given for one or more parameters I have gone in and changed all the fields in the database to be text I have checked the field names they are correct. The ldb file comes when I initialise the program. but as soon as I press the button I get the error. Any ideas? Ps I have included the <pre><code> using System.Data; using System.Data.OleDb; </code></pre>

Guidance

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.
