Disabling Menu Items

Return to Introduction  Previous page  Next page

For security reasons, you may wish to restrict some users from issuing some menu commands.  TN3270 Plus allows you to do so by adding registry entries to disable selected menu commands.

The following table lists registry entries you can use to disable menu commands. These entries can be placed in:

HKEY_CURRENT_USER\Software\SDI\TN3270 Plus\Configuration


HKEY_LOCAL_MACHINE\Software\Wow6432Node\SDI\TN3270 Plus\Configuration   (64-bit Windows)


HKEY_LOCAL_MACHINE\Software\SDI\TN3270 Plus\Configuration   (32-bit Windows)


Placing the registry entry in the HKEY_CURRENT_USER hive restricts the entry to a specific user. Placing the registry entry in the HKEY_LOCAL_MACHINE hive restricts all users on the PC. All the entries in the table have DWORD (32-bit) values. Set the value to 1 to disable the menu item or 0 to enable it. The default is enabled for all menu items.
