String simple problem

[Lior]

Hey...

When I saw the help for the String Data Type, I saw it can contain up to approximately 2 billion characters.
In fact, it should contain up to 2^31 characters, and this is exactly 2,147,483,648
But when I try to put in the string only 2 million characters, I get an error: "Out Of String Space"
Why?!
I use this simple code:

Dim X,A as String
A=Space(10000000)
X=A+A

In the 3rd line I get the Error.
Why?!
Any Ideas?

Has probably to do with your computer, on my NT Server with 128Mb RAM, I could run your code (although the machine became *very* slow, I didn't get an error....)

I tried it, too, on my computer (433 mHZ, 196MB of RAM) and it worked fine.

your problem lies with your maths.

Dim X,A as String
A=Space(10000000)
X=A+A

A+A will in fact = 20,000,000 (20 million) not 2,000,000 (2 million)

Guys,
I run this code on my Celeron 500, 64MB RAM.
And btw, I know it should be 20 million and not 2 million,
but string can contain up to 2 Billion!!! (2000 million!)
why the string cant handle only 20 million?!?!
Did Microsoft's VB Team Lie ?!

Any Ideas?

You need 2G of RAM, then or wait that terrible time while windows is swapping these 2G to your harddisk, i have on a mistake made a 400M string and it took me 15 min to wait.

your problem is in your hardware..
you should atleast have 128 mb. ram for this action.
I got 112 mb. and it didn't work wery well.
but when I tried it at my other comp with 128 mb. it worked.
