Lesson 19: Creating Multimedia Applications-Part I
In this lesson, you will learn how to create a CD player that can play a music CD or DVD. It allows the user select a track to play, to fast forward, to rewind and also to eject the CD. It can also display the track being played.
To be able to play multimedia files or multimedia devices, you need to insert Microsoft Multimedia Control into your VB application that you are going to create. However, Microsoft Multimedia Control is not included in the startup toolbox by default, you need to add the MM control by pressing Ctrl+T and select it from the components dialo.
