    I'm using the following code to get information on the current logged in user:

    VAR
    CurrentUser:        VisuUserManagement.VUM_User;
END_VAR

CurrentUser:= VisuUserManagement.g_VisuUserMgmtIntern.GetCurrentUser();

    If I call this with no user logged in, I get the screenshot below, as expected. When I log in, I can see the username, etc, as expected. However, when I log out, the username, password, user groups, etc stay as if I'm still logged in. I would expect to see empty strings in the username, and 0's in the groups, just like the initial screenshot. Do I have to reset it somehow?

    This doesn't work when you have multiple clients, so you must iterate over the clients and then get the required info per client.

    E.g. add this to a program which you call from the VISU_TASK

    VAR
    pClient : POINTER TO VisuElems.VisuElemBase.VisuStructClientData;
    dwTargetVisuGroupID : DWORD;
END_VAR

    VisuElems.VisuElemBase.g_ClientManager.BeginIteration();
WHILE (pClient := VisuElems.VisuElemBase.g_ClientManager.GetNextClient()) <> 0 DO
    IF pClient^.GlobalData.ClientType = VisuElems.VisuElemBase.Visu_ClientType.TargetVisualization THEN
        dwTargetVisuGroupID := pClient^.GlobalData.CurrentUserGroupID;
    END_IF
END_WHILE

    See for a general other way of using this "Client handling":

    if you just want to show the currently logged in user in the visualization, then just create a field with text %s and as text variable VisuElems.CurrentUserName
