some1 know how to use pointers in delphi \ c \ vb?
i mean like for example i have 2 variables:

asdf: string;
qwer: string;
asdf := 'qwer'
qwer := 'lol'

now i need to use asdf as a pointer, and get the data stored inside qwer.

i know u can do it in ASM, iunno how to do it in other compilers.

Delphi, I'm pretty sure it's

Code:

qwer : string;
asdf : ^string;

asdf := @string;


or something like that.

For C,

Code:

int hallo = 0;

int *hello = &hallo;


As for VB, I've got no clue.

A simple Gewgle search could quite probably yield the answer. =P

In VB6 you can use VarPtr, StrPtr, and CopyMemory to accomplish this.
