Ok this will be a pretty small tutorial ok you know all how to declare variables in vb6 & vb .NET right
ex

Dim TheString as String
Dim Number as Integer

but did you know that you can declare a variable in a much shorter way using symbols like this

Dim TheString$ 'String
Dim TheInt% 'Integer
Dim TheSingle! 'Single
Dim TheDouble# 'Double
Dim TheLong& 'Long
Dim TheCurrency@ 'Currency

so i also commented each line so you know what symbol do what but let me write it down

% - Integer
! - Single
# - Double
& - Long
@ - Currency

Ok this is the tutorial i know realy short but i hope i can get in handle for anyone of you :D Peace out

This was the old way of doing it (back in basic, basicA, gwbasic, qbasic, etc...)

VB tries to support legacy commands and conventions
(with minimal to no documentation) as long as it doesn't
go against it's current direction.

Excualy i seen the first string $ declaration in a QBasic code then i was wounding what it was.After reading a little and trying in VB6 i found it out xD
Sometimes taking a deep look into source code can make you learn a lot new stuff thx for the replies to my post

That's a cool bit of info. +rep

Very interesting. I prefer the "as" method even though it is more typing because it reads a lot easier. When I see

Dim sName$

I have to remember what $ means, where as

Dim sName As String

I don't have to remember anything. It reads easier.

It is useful when declaring constants, though:

Const MyLongConst = &HFACE&
Const MyIntConst = &HFACE%

I'm not really a .NET person so I don't know if they fixed this, but this is the way it was done in 6 and VBA.

Cool! :)

This is really cool, I never knew you could do it that way!

I would advise against it, just because it makes your program annoying to read.

Agreed, I think one of "Basic's" goals was to be easier to read.

If that were true then they would've used != instead of <> and allowed escape sequences in strings instead of forcing you to do this:

"Hello, World!" + vbCrLf + "New line."
