// This is called at every expiration of the NSTimer interval that we set at // startup time // Typically, in this type of design, the first thing to do is check all the // boundary conditions: // has the ball hit an edge of something (the room), has a point been scored, // is the game over, // has the ball connected with the player's or computer's paddle. // Note that all the code in the entire function is contingent on the game status being IN_PLAY. This // should be obvious that we only want the automatic part of the system to update if we're in the // middle of play. In any other state (NOT STARTED, GAME WON, POINT OVER) the player should determine // things (SERVE or not). // // Note also that this method also sets the game's status: // (1) If the ball is past the player's end, the computer has scored and we set POINT_OVER // (2) Similarly, if the ball is past the computer's end, the player scored and POINT_OVER as well. // (3) If the point total of a player is equal to the constant GAME_WON, we set status = GAME_OVER // (4) NOT_STARTED is set at startup in the viewDidLoad method. // -(void)gameLoop { if(status == IN_PLAY) { ball.center = CGPointMake(ball.center.x + ballSpeed.x, ball.center.y + ballSpeed.y); // move the ball // // If we turned on an LED in the last loop, then turn it off now // if (redLEDOn) { [self turnOffRedLED]; redLEDOn = NO; } if (greenLEDOn) { [self turnOffGreenLED]; greenLEDOn = NO; } // Has the ball hit the edge of the room if (ball.center.x > (self.view.bounds.size.width - WALL_MARGIN) || ball.center.x < (0 + WALL_MARGIN)) { ballSpeed.x = - ballSpeed.x; } if (ball.center.y > self.view.bounds.size.height || ball.center.y < 0) { ballSpeed.y = - ballSpeed.y; } // player scored against computer if (ball.center.y < 0) { // set status to hold status = POINT_OVER; playerScore++;

Error handling is important at all times in SQL Server, and it s never more so than inside transactional code. When you execute any T-SQL statement, there s always the possibility that it may not succeed. The T-SQL @@ERROR function returns the error number for the last T-SQL statement executed. If no error occurred, @@ERROR returns zero.

The PIM concept of ToDo corresponds to the BlackBerry Tasks application. This is an area where you can provide yourself with lists of things to be done. With access to the ToDoList interface, your app can chime in on what s important. Each ToDo encapsulates a specific task. ToDo is based on the VTODO spec that is included as a subset of the vCalendar specification. There is a close relationship between calendar events and todo tasks, but they are not the same. An Event should have a time associated; ToDos may have due dates, but can also simply be reminders of outstanding tasks. The following is an example of a simple VTODO.

Objects in SQL Server have a four-part name, and each part is separated by a period. For example, if you want to refer to a table named Employee in the Store database that Jim created (so Jim is the owner), and the computer name is called Server1, you could refer to the table in this way: Server1.Store.Jim.Employee. There are some shortcuts to getting around this. For example, if you omit the computer name (Server1), the local computer is assumed. If you omit the database name, the default database for the connection is assumed. If you omit the owner name (in this case, Jim), then the owner will again be inferred based on connection parameters. It is all these conditions that permit you simply to refer to an object by its name alone. Not all four parts of the name are required, but at a minimum, you must specify the object name itself and then specify each name part in turn from right to left. In other words, Server1.Employee would not work. If you specify the name of the computer, you must also specify the name of the database and the name of the owner.

2. Accept the default location for the deployment. ClickOnce will create a virtual directory at the specified location and will copy the application to the directory. Click Next.

One of the challenges of life as a Mac OS X Server administrator is that Mac users (typically artists and designers) generally work with large files. In the most extreme cases, single files can be in the hundreds of gigabytes. Mac users accustomed to files normally 100MB in size are less likely to notice that they are sending files to each other that are too big for emailing. So, limit files, but make sure to communicate what s appropriate with the users in order to reduce support calls. Explain when to use FTP or file sharing and when not to use it.
