Is it posssible to get the address of a variable in visual basic
I mean something in c++ like
int *ptr;
int a=1;
ptr = &a;

thanks for any help that can be offered,

Why do you want to do that? What are you trying to achieve?

Well... Technically, yes you can. But why do you want it? There
really isn't a lot you can do with it once you have it anyway, and
anything you manage to do is likely to be dangerous anyway

There is no direct equivalent.

Depending on the situation, one of the following solutions may apply:

* Use references instead of pointers (see: reference types, value types,
operators '=', 'Is', 'IsNot').

* Declare the parameter as 'ByRef' when using p/invoke.

* Use 'Marshal.Alloc*' to reserve an unmanaged block of memory and then
use 'Marshal.Write*'/'Marshal.Copy' to copy data to the memory area. Then
you can pass around the pointer pointing to the memory location.

* Use 'GCHandle.AddrOfPinnedObject' to pin a managed object in memory
(rarely useful).
