Visual basic 2008 Express edition error?

hello,
When i start making hacks it getting underlined like this:
it say it is an error!
can anyone explain me how to fix that shit?
but this one is not from a hack
picture:

Simple, make it
Sendkeys.send(224Ef2), as in VB.net (VS2008) You need () around pretty much everything.
(vb6 = fail )

EDIT: You also might need "'s around that.
