Lesson 15: Creating Multimedia Applications

You can create various multimedia applications in VB that couold play audio CD, audiofiles, VCD , video files and etc.
To be able to play multimedia files or multimedia devices, you have to insert Microsoft Multimedia Control into your VB applications
that you are going to create. However, Microsoft Multimedia Control is not normally included in the startup toolbox, therefore you need
to add the MM control by pressing Ctrl+T and select it from the components dialog box that is displayed.
