A few more quick newb q's

I think php and visual basic can both be used to build the same kinds of things… is there a reason why someone would chose to one of these over the other? does one of these have a brighter future than the other?

second question, I have cold fusion on this computer (jeez I probably sound dumb lol) whats it used for? is it some sort of ide for dynamic languages like php and vb?

third question, if cold fusions not and ide, and you recommend either php or vb, can you give me a recomendation on an ide to use… I know there’s like netbeans or somthing and a lot of others, not sure where to start though.

Appreciate the help
