Some Axapta system administrator may feel it is really annoying that Axapta allows the user to create multiple Axapta sessions and log in as the same user. If you want to give the user notification prior to logging in as the same User ID, here comes the solution.
Under the Info class, modified the startupPost method like the codes below:
int num = 0;
int maxSessions = Info::licensedUsersTotal();
currentUserId = curuserid();
for(counter = 1; counter < maxSessions;counter++ )
session = new xSession(counter, true);
if(session && session.userId())
select firstOnly userInfo
where userInfo.id == session.userId();
if (userInfo && (currentUserId == session.userId()))
if (num > 1)
if(box::yesno("The same user id can’t log in twice. Do you want to log in anyway? ",
DialogButton::Yes, "Log in", "Log out") == DialogButton::No)
Please notice that, if you modify the startupPost method of Application class, that works only in 2-tier environment. For both 2-tier and 3-tier environment, it is recommended to modify the startupPost method of Info class.
