Memory Access in VB.Net

[Morrislgn]

Hi Folks,

Quick question - is it possible to access a memory address using vb.net?

For example, if i want to access the memory address 0x00000002 I can type this in C#:

private const int th32CS_SNAPPROCESS = 0x00000002;

But when I try what I think the vb.net version should be:

Private Const th32cs_SnapProcess As Int32 = 0x00000002

However, VS doesnt seem to like this code.

Any ideas why? Is it possible to access memory in vb.net?

All suggestions gratefully recieved!

Thanks

The hexadecimal prefix in VB is "&H", not "0x". VB.NET doesn't support pointers though, so a memoery address won't do you much good.

Cheers for the advice!

I believe you can use the Marshal class to go in and out of managed memory if that helps any

Note that the memory model in the CLR does not guarantee that a variable will stay at the same address - the GC can move things around to make a bit of space. If you have to reference a variable by address (and I suggest that you don't really) then you have to "pin" it to prevent it being moved.
