Running BC-Wedge as an NT/2000 Service
The following information was contributed by one of our customers
who was able to run BCWedge as a service under Windows NT/2000.
Overview:
A utility called srvany.exe that comes along with the Windows NT
Resource Kit is used to install BC-Wedge as a NT Service with the
following benefits.
- When applications run as a service, they are not closed during
logoff so users do not need to start them each time they log on,
nor can they kill them if the services control has been restricted
to the users.
- Server applications can service requests even when no user is
logged on.
- Applications can run and perform tasks specific to a logon account
that is different from the user who is currently logged on.
- The wedge process will not be visible in the taskbar or system-tray,
so users cannot make modifications.
Installing :
Create a directory c:\service and copy the following files
in it.
Instsrv.exe
Srvany.exe
 If
you do not have the Instsrv.exe and Srvany.exe files, click here
to download them in a self extracting ZIP file.
Note: The file Wedge.bat (included
in the archive) is a batch file that can be used with WinWedge when
running that program as a service and is NOT needed when running
BC-Wedge as a service. More information
on running WinWedge as a service.
To run BC-Wedge as a service:
1. Start BC-Wedge manualy, configure it for the right COM
port and make other necessary modifications to the software, like
Beep PC On Good Read or Postamble Keystroke(s).
 |
Do NOT mark the checkbox Load With Windows At Startup,
otherwise BC-Wedge tries to load itself again with every next
logon.
Important:
After configuration, minimize BC-Wedge to the taskbar and
keep it there untill the next shutdown or reboot.
This minimized state is stored in the registry, so the next
time it will start, it is minimized as well.

2. click on Start > Run and type:
Instsrv Wedge C:\Service\Srvany.exe
(Where "Wedge" will be the name of the Service).
3. Click Services in Control Panel,
(under Administritive Tools in Windows 2000). Click on the service
"Wedge" and then click Startup to display the startup
dialog box. There click Automatic. In the Logon On as...
box, choose Local System Account. Mark the checkbox:
Allow service to interact with desktop.
4. Start Registry Editor using Regedit.
-
Add a new subkey called Parameters in the following
registry location:
HKEY_Local_Machine\SYSTEM\CurrentControlSet\Services\Wedge
-
In the new Parameters subkey create the following
String Entry (REG_SZ) with its value:
Application Type:REG_SZ
Value: "C:\Program files\Bc-wedge\Bc-wedge.exe"
Start the newly created service manually, or boot the o/s to activate
the changes.
Note: Due to unknown reasons at this time, it is not possible
to use the Wedge redirection before or during the Logon session.
Although the Wedge service is running at that time, the user needs
to logon first in order to use the redirection.
