Option Explict...No need? MUST READ

As we here are probably already aware if the statement Option Explicit appears at the top of a module then all varibles used within must be pre-defined.

The question I put to you all is:

Why does VB, or Microsoft if you prefer, allow coding without the use of Option Explict? It's not rocket science to decalre a varible, so why is it not enforced?

Oh, if anyone read my posts from yesterday regarding finding users logged into an NT network and the puter they are logged into, well I've worked it out. Found some code at planetsource code, here's the link: http://www.planetsourcecode.com/vb/s...11317&lngWId=1

There is only one problem with the above code and that is if a user doesn't access the network server for, say 20 minutes (can't remember exact time delay) then they are displayed as being offline...must be someway around this...Have fun.

Oh yea, answer my original question you ladder monkeys :p

It was a design decision - simple as that.....

Read pages 9 - 11 of Hardcore Visual Basic by Bruce McKinney for more info.....you can find it here.....

well if you don't use Option Explicit, you can use variables without defining them first.

i.e.

VB Code:

bob = 3

dunno whether this will make bob a integer, long or what though?

I understand that, but it doesn't have any benefits...:(

I feel that must have been a 2 in the morning descision in the board room...

Bloke1: *drag* hey man, let's allow users the ability not to be forced to define varibles. *exhale*

Bloke2: Yea...*drag* That'll get them well confused...This is good gear man :D

The above opinion is not one of mine. I have Alien Hand Syndrome which is a recognised illness, can't be blamed...No, leave the keyboard alone *SLAP*

bob will be declared as a variant internally, and the variant will contain meta info about it's contents to define what type it is.....thats part of the reason that variants are slow.....

well i suppose the only benefit is that it allows you to create a program extremely fast since you don't have to bother with a few extra lines of code etc, checking variable types etc.

although it will be buggy, and generally, bad programming...

not something i'd recommend, anyway :)
