In plain dos I use XMS to allocate and lock physical memory and it works, but when I run the software under a Windows Dos Box the operating system halts my program on the lock request ! I've heard about VDS services but I've not yet understand if it can resolve the problem and how to use it exatly. I appraciate any kind of help. Thanks, Simone Navari. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG
