Is Visual Basic hard to learn?
Visual Basic is fairly easy to learn because it is an interpreted language so it
is easy to debug. If you get a good book or find a good site you should be able to learn
how to program in Visual Basic fairly fast. For beginners Visual Basic is a great first
language that shouldn't get you to frustrated.
Can Visual Basic create an actual .exe file?
Before Visual Basic 5.0 the answer was no. It could create a file with a .exe
extension but really it was just pseudo code and still had to have .DLLs sent with it for
it to work. Now with the release of Visual Basic 5.0 you can create an actual .exe file
that does not require any extra files unless you use things like custom controls.
What is Option Explicit?
If you turn this function on you will be forced to declare all variables before
using them in the program. I feel it is a good idea to turn this on for a couple of
reasons. One is the fact that it is just good programming format to declare all of your
variables. It makes it easier for you or other people to read and understand later. It
also makes it easier to debug because when you misspell a variable, you will get an error
instead of just making a new variable and causing a bug that will later be extremely hard
to find.
Is the variant type slower than using other variable types?
Usually yes, even if it is not any faster it almost always takes up less memory.
If you have a choice between using a variant declaration compared to another such as
string or integer then use the other.
