Hi All,
I've been advised to use option strict. I've tried to read up on this, all i
can find is that it...
"disallows implicit narrowing conversions"
This kinda makes sense - Means I have to explicitly cast or convert data
when comparing/setting two different data types right?
Is there any more to it than this? What are the benefits of using option
strict?
Regards,
Simon. 12 1536
Option Strict generally leads to better code.
How is that?
Well, for one, it prevents programmers from taking shortcuts and declaring
everything as object. Not only is the final code more intuitive to the end
user, you might prevent instances of boxing/unboxing not to happen.
Secondly, it allows you to catch more errors at compile time, i.e. type
mismatches, undeclared types etc. And an error caught at compile time is an
error saved at runtime.

Option Strict also "disallows late binding".
Late binding is when the application doesn't know until run time what an
object's true type is. This causes more overhead to your application and
opens the door to errors.
Not allowing late binding (and therefore enforcing early binding) means that
all objects must know their type at design time, because of this, the
IntelliSense in VS.NET tells you what class members are allowed on the
object.

The most important thing is that it turns potential runtime errors into
compile time errors.
Compile time errors are much easier and less expensive to fix, and they'll
never reach your users.
