1. Microsoft® Small Basic Sound, Program, and Text Objects Estimated time to complete this lesson: 1 hour

2. Sound, Program, and Text Objects In this lesson, you will learn about: Using the Program object to manage execution of Small Basic programs. Using the Text object to work with text-related functions in Small Basic programs. Using the Sound object to enable playback of sounds in Small Basic programs.

3. Introduction to the Program Object To better understand the Program object, let’s take a look at the example displayed. output In this example, notice the use of Delay and End operations. The Delay operation sets a fixed time delay for the program to execute, and the End operation ends the program execution. When creating programs and working with various objects and operations offered by Small Basic, you might want to control the execution of your program. You can use the Program object to manipulate how your program executes.

4. Exploring the Program Object The Program object also allows you to retrieve information about the arguments passed to your program. Let’s take a look at an example to understand how you can use the Program object to determine the count and value of arguments passed to a program during execution.

5. Introduction to the Sound Object After working with arguments and using the Program object, let’s explore some other interesting aspects of Small Basic. Did you know that you could include sounds in your Small Basic programs? In fact, you can choose from sample sounds provided in the Small Basic library. Look at the example displayed. You can work with sounds in your program by using the Sound object with operations such as Play, Pause, and Stop. The output of this example plays, pauses, and stops the specified sound file at regular intervals.

6. Now, let’s take a look at an example to understand how you can play specific sounds, such as a bell ring, chime, or click, in your Small Basic program. Exploring the Sound Object The output will play the sound of a bell ringing, a chime, and a click, at regular intervals. Observe the use of the PlayAndWait operation in the example. The PlayAndWait operation plays an audio file and waits until the audio has finished playing.

7. Introduction to the Text Object Small Basic also offers useful operations that help you work with text. In Small Basic, when working with text, you can use the Text object and its various functions and methods to perform operations on the text. For example, to find out the length of a text string, you can use the GetLength operation. Let’s learn some more operations of the Text object with an example... For example, you may want to convert all names to uppercase. Alternatively, you may want to find out whether a portion of text contains specific information.

8. More on the Text Object In this example, the user inputs an e-mail address. Using the IsSubText operation of the Text object, you can determine whether the e-mail address is valid or not. Let’s take a look at another example to understand some more operations of the Text object.

10. To get the character code for a specific Unicode character, you can use theGetCharacterCodeoperation.

13. If the answer is correct, the program must display a success message along with a chime sound.

14. If the answer is incorrect, the program must display the appropriate message along with the sound of a bell.
