Since I was ten that I'm acostumed to use basic language and Visual Basic. Now I have started to learn C and I see there are things similar and other diferent. I don't know what C can do that Visual Basic cant do.

I suppose it's more "wise" to use C where Visual Basic fails. So, what should I try to learn better in C in order to use C language to complete VB?

I'm not interested in doing things in C that can be also done in VB, I think it's a waste of time, no?
