GetUserName() return "SYSTEM" FOR SYSTEM PROCESS

[vicky00000]

For getting the user name in, we are call the GetUserName() in the Application context, in which case we get it right if the Application is launched form logged in user. But in case of system process GetUserName() return "SYSTEM" as current user. There is any API or Method to get the current user name in system process? THANKS IN ADVANCE

How will that work from a service running as a different "user"? Mark

For systems with fast user switching (XP+) where more than one user can be logged on at the same time, maybe something like this:

#include <WtsApi32.h> // link to WtsApi32.lib
...
DWORD dwSessionId = WTSGetActiveConsoleSessionId();
if (0xFFFFFFFF != dwSessionId)
{
LPTSTR pUserNameStr = 0;
DWORD dwBytesReturned = 0;

if (WTSQuerySessionInformation(WTS\_CURRENT\_SERVER\_HANDLE, dwSessionId, WTSUserName, &pUserNameStr, &dwBytesReturned))
{
    // ... use pUserNameStr ...

    WTSFreeMemory(pUserNameStr);
}

}
