Version 24.0 for Windows

What’s new in the version 24.0

We are happy to announce today that a major update for Net Control ² Classroom, Net Control ² SmallClass and Net Control ² Professional for Windows, the version 24.0 is already available for download.

This update introduces significant changes in the internal structure of the student module, which will provide better compatibility with user mode settings and applications. The update is more focused on improving the usability of existing tools and features, tuning of the user interface details and constructing a base for further products development.

The new version includes the following changes:

Redesigned the Student Console:

  • Docked and Windowed modes. The Docked (classic) mode shows the console as a docked to the right side of the screen window. In the Windowed mode, the console is shown as a standard window on Desktop, which can be resized, minimized, restored by clicking the taskbar icon and so on. The windowed mode is more adapted for simultaneous work of students with the Student Console and other applications, and provides faster and more flexible access to Net Control 2 Student Console’s features.
  • Student Console displays information in a smarter way, adapting content to the screen and console dimensions.
  • Student Console’s blocks are redesigned to be more compact and informative.
  • New information blocks are available in the Student Console: license information, more detailed lesson information, connection time, detailed system and network information on the About page.

The file collection subsystem has been completely redesigned, allowing students to send files to teachers. Students can send files to teachers just by dragging them onto the Files panel of the Student Console. The classic AutoSend folder is also available.

The feature supports two modes: the simpler send-and-delete mode assumes that files placed to the folder will be sent and subsequently deleted from the folder; and the more sophisticated Keep and Synchronize mode keeps all files on the student computer with providing the necessary versioning.

The student module runs now under a user account, when a user is logged in in the system. This provides better compatibility and interoperability with other user-level applications, system settings and eliminates known restrictions of the system account.

The automatic update subsystem was completely redesigned for more frequent and transparent updates.

This update address also several improvements in the sound subsystem, which is used by different tools in the software, including lesser latency of the captured audio and support of the system audio capture in the Remote Desktop / Control tool.

Version 22.1 for Windows (January 2022)

Net Control 2 Classroom, Net Control 2 SmallClass and Net Control 2 PRO for Windows are updated to the version 22.1

Version 22.1 includes:

New Remote Desktop and Broadcast Desktop engines. Significantly improved the performance of Remote Desktop (Control) sessions, usually it is in several times faster in comparison with the previous versions. Improved performance of Broadcast Desktop engine and better tolerance to network packet losses during the transmission. Users are able to change scaling and compression levels during the broadcast and control sessions, which may be useful when working with high- and ultra-high-definition resolutions.

Monitor. The new computer use monitoring tool replaces the legacy Event Monitor tool. With the new tool, Instructors receive immediate information of all applications used at the time in the classroom, individually per each user: what application is running at the moment, what document or a web link is opened in the application, usage statistics by time (how long the application is used since last switch; the total use time and the percent of use per session). You will get a notification if the application is opened from a non-standard location (e.g. from a removable storage). The tool will alert if no activity is found on the student computer within some time.

New Timers tool allows Instructors to show customizable timers on User computers: countdown or count up timers, for any defined by Instructor time; show the current time clock, execute actions when the timer elapses (e.g. notify the Instructor, play a signal, shutdown the computer and so on). Three designs and three sizes of timers are available for customization.

UI improvements: updated top toolbar icons, adapted for UHD displays; added several tooltips, other minor improvements.
