About the Mirror Driver

The 7.0 revision of hotComm introduced the mirror driver technology for presenters using the Timed Camera. Image changes are determined by comparing screen activity with a mirror copy of the screen, instead of with a saved image.

The hotComm Mirror Driver is installed automatically in hotComm Standard/Pro and hotComm CL (for Presenters), if you answer "Yes" to the question asking if you plan to present dynamic content. The Mirror Driver is not included in hotComm Lite or in hotComm CL (for users).

Because the hotComm Mirror Driver is installed as a device driver, we are providing information about manually instsalling or uninstalling in this article, should you need to do so.

An "MD" icon on the bottom line of your hotComm window shows the Mirror Driver status.

Icon Description
Mirror Driver is loaded (yellow square with a black M).
(no icon) Mirror Driver is not installed.


Vista note: In Windows Vista, you run a special version of the hotComm, the hotcomMD.exe executable, which launches the hotComm Loader with Run as Administrator to load the Mirror Driver and then starts the usual hotComm executable (hotComm.exe) normally. Vista may ask for permission to launch the hotComm Loader. During installation on a Vista computer, your hotComm desktop shortcut and your Windows Start menu entries are configured to launch the hotComm Loader.

To see the setting on the desktop icon, right-click the icon and select Properties, then click the Advanced button on the Shortcut tab, and you'll see that Run As Administrator is checked.

Command line options

Command line options for the Mirror Driver are below. For instructions on adding a command line parameter, see www.hotcomm.com/faq/faqk30.asp, except add /mdx or /mdy or -gg instead of -k30.

Option Explanation
/mdx Do not load the Mirror Driver. Use this option if the Mirror Driver is correctly installed but you do not want to use it.
/mdy Load the Mirror Driver. Use this option if the Mirror Driver is correctly installed and you want to use it. (As of revisions after 7.30.010, the Mirror Driver is not loaded unless you have the /mdy option. The files are provided by the installer, but you must install them and add the /mdy option to your startup command line.)
-gg (that's lowercase GG) Keep the Mirror Driver active until you close the hotComm. Usually, the Mirror Driver is turned on whenever you open an application remotely and turned off when you close the application. When it is turned on, you normally get a brief screen flash as it turns the Mirror Driver on and off. With th -gg option, you'll only get a flash the first time you remotely access an application.
