Visual Basic Help Needed

Hi its me again...

ok...i'm making an e-leraning package for school and i need to use some VB code inside it - for accessibility and other stuff. I'm designing the package in powerpoint but i am going to use the VB code editor to add my code.

I need to find a way to allow the user to change the resolution of the package and lower the volume of the sound by using a trackbar or something.

Anyway i think you will need to call a mulitmedia API and because at school we have very limited previligies i dont think i will be able to call one into VB.

So any ideas how i can do this using the VB code editor in powerpoint?

Thanks in Advanced...cya l8er...

P.S I cant have any extrenal files like .vba or .class. Everything needs to be built internally through PowerPoint. (i know it probably cant be done but what the heck...maybe)

Anyway...

thanks...
