Environment Variables (Registry Values)

DisableCommandLine
The environment variable called DisableCommandLine lets you disable the Command Line
option in the Customize Toolbar Button dialog box, thereby restricting users from running
executable programs within iNEWS on the PC. DisableCommandLine also disables any
existing toolbar buttons that utilize the Command Line option.
Environment variables are workstation specific, not user specific; therefore an Environment
key must be added to the Registry on any PC on which you want to prevent users from
creating custom toolbar buttons that execute programs via the Command Line option. If a
registry value is not found in the Environment key of the Registry, then the default
behavior—no restriction—is observed at the workstation.
To create and define this value thus disabling the command line option:
1. Open Registry Editor. See “Registry Editor” on page 240 for more information.
2. Navigate to the Environment key, and open it.
3. Right-click on the right side of the Registry Editor window. A pop-up menu appears.
4. Select the DWORD Value option to create and define a new registry value of type
DWORD in the Registry Editor.
5. Type the name of the new value: DisableCommandLine.
6. Press Enter.
7. To set the Value data option:
a. Right-click on the DisableCommandLine value.
b. Select Modify.
The Edit DWORD Value dialog box appears.
c. Type 1 (one) in the Value data field to disable the Command Line option.
If set to zero (0), the Command Line option will remain enabled, so it will not
appear grayed out in the Customize Toolbar Button at the iNEWS Workstation.
