Getting a users network ID

Hello,

Let me preface this post by saying I am in no way a PB developer. I have inherited several PB Classic applications that need some work in converting them to run on Windows 7 64bit.

Right now I am trying to get a user's network id using the following code:

FUNCTION long GetUserNameW(ref string UserName, ref ulong BufferLength) LIBRARY "ADVAPI32.DLL"

and then calling GetUserNameW with:

long ll_ret

ulong BufferLength = 100  // you may need to adjust this. see Note

is_network_id = Space(BufferLength)

ll_ret = GetUserNameW(is_network_id, BufferLength)

is_network_id = lower(is_network_id)

This works as expected when debugging, however, when I click run from the PB 12.5 classic IDE, it doesn't return the network ID.

Can someone point me a direction towards figuring this out?

Thanks,

Chris
