DirectCast and CType will throw an exception if they can not
cast/convert the object to the target type. TryCast will not throw an
exception, but return nothing.

Have a look at your keyboard. In the top left, do you see the
"Esc" key there? On it's right, there's a key that reads "F1".
If you press it, you will get a lot of documentation. This
feature is even case sensitive. So, if you press it while
the caret is placed on one of these keywords, you will
get help about them.
