I have a project that was created all with Option Strict OFF. Works great,
not a problem with it. But if I turn Option Strict ON then I get a LOT of
errors.
My question, should I even care about Option Strict?
What advantages do I get with Option Strict On?
Does better type statement make my code run faster?
If anyone knows THE ANSWERS! please fill me in. I have ideas and belief but
I would once and for all like to know what the difference is.
Thank in advance

There are likely many reasons why you should have OPTION STRICT ON all the
time.
My main reason for using it is to watch for narrowing conversions. Places
in code where I might inadvertanly perform a conversion from a double to a
single ore perhaps any floating point value to an integer value.

If you notice the different between having it ON or OFF, then you aren't
programming very well.
Turn it on and fix the errors.
Clyde,
It is up to you, when you are programming in an access kind of way,
scripting way, you can use option strict of and let the computer do things
for you at run time.
This means directly that your program becomes more insecure and does not
have the performance as it could be.
A simple sample.
When you say
dim a as object
a = 1
dim 1 as integer = a
Than this goes with option strict of, however the program does now not know
what conversion should be done at run time and solves it at that moment.
With option strict on it has to be
dim 1 as integer = Cint(a) 'or any other casting, conversion, parsing
command and is it done at run time.
Before you say it, I myself find it strange that this is not build in
automaticly, because the compiler knows this at run time. He tells you that
you that Option Strict Disallows you to do an implicit conversion from
integer to object.
Therefore he can do that in my opinion in design time himself at least by
giving a default which can be choosen with one click. (Or with an option
which tells always to set the standard conversion function in this kind of
situations).
I hope this helps?

I believe using a lot of late binding will cause your program to run quite a
bit slower.

It definitely will affect performance - not to mention it will greatly
increase the chances of making some hard to find logic errors.

I don't know if it affects performance or not. But I do know this. I

Hello,
If I leave Option Strict Off I can use the following
syntax to read data from a Lotus Notes application (a
NotesViewEntry object represents a row of data from a
Lotus Notes View - like a record in a sql Server view)

Dim entry As Domino.NotesViewEntry
Dim obj As Object
str1 = entry.ColumnValues(0)

I fully expected the lack of a way to set Option Strict globally to be fixed
in SP1. I can't seem to figure out if it has been fixed or not. It still
seems we have to add the declaration at the top of each and every single
code module. Am I missing something here?

A wise man once said: "Never put off until runtime what you can fix at compile

Actually I think he said it about 10 minutes before I started this post.
I am a firm believer, like the man in question, in "Option Strict On" by
default.
Actually I don't believe I have code where this is not the case.
