The circle function draws a circle on a surface. It takes the center point and the radius of the circle (the radius is the distance from the center to the edge). Like the other draw functions, it also takes a value for the width of the line. If width is 0 or omitted, the circle will be drawn with a line; otherwise, it will be a solid circle. Listing 4.11 draws randomly filled circles on the screen, in a random color. Listing 4-11.

CloseConnection) To avoid keeping the connection open for too long, you should avoid complicated or timeconsuming operations while iterating the resulting IEnumerable collection And you should especially avoid any user interaction with the collection, for the same reason For example, the following example, which rewrites the previous example so the user can move on to the next record by pressing Enter, would be bad for database performance: for row in contactsTable do for col in rowKeys do printfn "%s = %O" col (rowItem(col)) printfn "Press <enter> to see next record" read_line() |> ignore. pygame.init() screen = pygame.display.set_mode((640, 480), 0, 32) while True: for event in pygame.event.get(): if event.type == QUIT: exit() random_color = (randint(0,255), randint(0,255), randint(0,255)) random_pos = (randint(0,639), randint(0,479)) random_radius = randint(1,200) pygame.draw.circle(screen, random_color, random_pos, random_radius) pygame.display.update() asp.net upc-a UPC-A Barcode Generator for ASP .

If you want to use the collection more than once or let the user interact with it, you should generally convert it to a list or an array, as in the following example: let contactsTable = execCommand "select * from Person.Contact" "MyConnection" let contactsList = Seq.tolist contactsTable Yes, connections will be closed when the cursors are garbage collected, but this process usually takes too long, especially if a system is under stress. For example, if the code you are writing will run in a server application that will handle lots of concurrent users, then not closing connections will cause errors because the server will run out of database connections. dataConnection.Close(); } catch(Exception e) { Assert.Fail("Error: " + e.Message); } } [TearDown] public void Destroy() { try { OdbcConnection dataConnection = new OdbcConnection(); dataConnection.ConnectionString = connectionString.ToString(); dataConnection.Open(); OdbcCommand dataCommand = new OdbcCommand(); dataCommand.Connection = dataConnection; // Build command string StringBuilder commandText = new StringBuilder("DELETE FROM Products WHERE ProductID = "); commandText.Append(productID); dataCommand.CommandText = commandText.ToString(); int rows = dataCommand.ExecuteNonQuery(); // Make sure that the DELETE worked Assert.AreEqual(1, rows, "Unexpected row count, gasp!"); dataConnection.Close(); } catch(Exception e) { Assert.Fail("Error: " + e.Message); } } Data binding is the process of mapping a value or set of values to a user interface control. The data does not need to be from a relational database, but it is generally from some system external to the program. The process of accessing this data and transforming it into a state where it can be bound is more complicated than the binding itself, which is straightforward. This is why I cover the topic in this chapter, rather than in 8. The next example shows how to bind data from a database table to a combo box: open open open open open open System System.Collections.Generic System.Configuration System.Data System.Data.SqlClient System.Windows.Forms
