ASAIK, Borland doesn't encapsulate these functions into a VCL but you can still use the Windows API's GetUserName() and GetComputerName().

The following snippet came from October 1999 issue of C++Builder Developer's Journal. You can read the entire article online at

http://bcbjournal.org/articles/vol3/9910/Who_is_using_your_program_.htm

char buf[300];
DWORD bufSize = sizeof(buf);

bool success = ::GetUserName(buf, &bufSize);
if (success)
    lines->Add("Network user name = " + String(buf));
else
    lines->Add("Unable to get network user name.");

bufSize = sizeof(buf);
success = ::GetComputerName(buf, &bufSize);
if (success)
    lines->Add("Network computer name = " + String(buf));
else
    lines->Add("Unable to get network computer name.");

You can just use the getenv function of stdlib.h. This will retrieve environment variables of the local computer.

Environment vars that would work are:
- USERNAME
- COMPUTERNAME
