I posted the code above, that's exactly what I did. The password is saved in the connection. It doesn't work, it just opens up the UI, because the connection isn't "logged in" and there is no CLI command that I could find to get the connection to logon before trying to use it. But for some reason, double clicking on the connection in the UI takes care of this automatically, but the CLI does not.
Unfortunately, we couldn't reproduce the issue - it's possible to connect to a remote Host machine in the Full Control mode using command line parameters. Could you please clarify if you're running the following command, i.e. without the "name" parameter, but just its value?
rutview /navsystem /fullcontrol
If this is the case, then, indeed, the Full Control mode is not initiated, it just opens the Viewer main window even if the password is saved for the remote connection entry. Could you please try running the following command instead and see if it works this way?
