Example

Dim conn As SqlCeConnection = Nothing

Try
    File.Delete("Test.sdf")

    Dim engine As New SqlCeEngine("Data Source = Test.sdf")
    engine.CreateDatabase()

    conn = New SqlCeConnection("Data Source = Test.sdf")
    conn.Open()

    Dim cmd As SqlCeCommand = conn.CreateCommand()
    cmd.CommandText = "CREATE TABLE myTable (col1 INT, col2 MONEY, col3 NVARCHAR(200))"
    cmd.ExecuteNonQuery()

    ' For optimal performance use base table access
    '
    cmd.CommandText = "myTable"
    cmd.CommandType = CommandType.TableDirect

    Dim rs As SqlCeResultSet = cmd.ExecuteResultSet(ResultSetOptions.Updatable Or ResultSetOptions.Scrollable)

    Dim rec As SqlCeUpdatableRecord = rs.CreateRecord()

    ' Insert two records
    '
    rec.SetInt32(0, 34)
    rec.SetDecimal(1, System.Convert.ToDecimal(44.66))
    rec.SetString(2, "Sample text 1")

    rs.Insert(rec)

    rec.SetInt32(0, 35)
    rec.SetDecimal(1, System.Convert.ToDecimal(94.25))
    rec.SetString(2, "Sample text 2")

    rs.Insert(rec)
Catch e As Exception
    MessageBox.Show(e.Message)
Finally
    conn.Close()
End Try

SqlCeConnection conn = null;

    File.Delete("Test.sdf");

    SqlCeEngine engine = new SqlCeEngine("Data Source = Test.sdf");

    cmd.CommandText = "CREATE TABLE myTable (col1 INT, col2 MONEY, col3 NVARCHAR(200))";
    cmd.ExecuteNonQuery();

    // For optimal performance use base table access
    //

    cmd.CommandType = CommandType.TableDirect;

    SqlCeResultSet rs = cmd.ExecuteResultSet(ResultSetOptions.Updatable | 
        ResultSetOptions.Scrollable);

    SqlCeUpdatableRecord rec = rs.CreateRecord();

    // Insert two records
    //
    rec.SetInt32(0, 34);
    rec.SetDecimal(1, (decimal)44.66);
    rec.SetString(2, "Sample text 1");

    rs.Insert(rec);

    rec.SetInt32(0, 35);
    rec.SetDecimal(1, (decimal)94.25);
    rec.SetString(2, "Sample text 2");
