I was interested to enumerate all running Exe and following code does it.
But I found, that under NT/2000 it's possible to retrieve also DLL's list.
I thought that this knowledge can be useful, for example, to detect "gifts" in own process.
Somebody knows how to retrieve the DLL's list under 9x ?
(it's not very important and I already solved initial task, but interesting ...)
