- New option --command <action> <params> to send commands to
a running instance of openvpn-gui.exe
Supported actions are
connect, disconnect, reconnect
each of which takes the name of the config (with or without the
extension .ovpn) as a parameter;
disconnect_all, exit
which take no parameter and
silent_connection
which takes an optional parameter = 0 or 1 (1 is the default)
Examples: with the gui running, start a new instance as
openvpn-gui.exe --command disconnect myvpn : ask running instance
to disconnect myvpn if connected
openvpn-gui.exe --command status myvpn : ask running instance
to show the status window for myvpn if available
openvpn-gui.exe --command disconnect_all : ask running instance
to disconnect all active connections
- The second instance exits after issuing a SendMessage to the
already running instance. If no action is specified, the running
instance is notified to show a balloon to alert the user
- These messages may also be sent from scripts as COPYDATA messages
with the wData element specifying the action to execute and lpData
a pointer to the parameter. The dwData param must be one of
WM_OVPN_xxx with xxx = START, STOP, RESTART, STOPALL, EXIT or
SILENT. See main.h for their values.

- This works the same way as restart button in the status window
but is more conveniently accessible from the tray menu.

- Effective only when username and password are saved.
- The user may interrupt auto submission and edit the username/password.
- If silent_connection is on the dialog is bypassed without any delay.
v2 changes:
- Display message in normal text color and show remaining time

- Flag password and username input if these contain an invalid character
(currently only embedded '\n' is disallowed). Shows a popup when OK
is pressed so that the user can correct the input and resubmit.
- Add an error message to the log when the management i/f returns
ERROR for incorrectly parsed commands. Otherwise such errors go
unnoticed.
Note: IDS_ERR_INVALID_USERNAME/PASSWORD need translations.

- "Wrong username or password" message shown in the auth userpass dialog after
an auth failure
- "Wrong password" message shown in the private key password dialog after a
password failure.
These message texts are colored red by default (TODO: make the color customizable)

Note: IDS_NFO_TOKEN_PASSWORD_CAPTION and IDS_NFO_TOKEN_PASSWORD_REQUEST
strings need translation.
TODO: support for selecting pkcs11-id from the GUI

- Add a base64 decode function using Windows CyptoAPI
- Move multibyte to widechar conversions to a function
- Add config name to caption of password dialogs to help user
identify the request
- Add new dialog template for generic password/PIN requests
and use it to handle dynamic challenge
Note 1: if dynamic challenge response verification fails, an auth-failed
message is returned by the server causing the GUI to clear any saved
password even if the user-auth dialog itself succeeeded.
Note 2: Dialog template ID_DLG_CHALLENGE_RESPONSE added to language
files may require translation.

Sometimes gracefully stopping openvpn fails leaving the
process running in background. This causes restarting of
connections to fail until those processes are manually killed.
- Read process ID from interactive service to get process
handle when openvpn is started by the service.
- Add a last resort method to forcefully terminate openvpn
process that fails to exit aftier sending stop signal. Terminate
is triggered after a 3 second timeout following Stop.

Option ediitng dialogs are in two tabs: General and Advanced.
Proxy related options are left in the proxy tab. Options
config_dir, config_ext, log_dir, script timeouts and
service-only flag are in the Advanced tab. All other more commonly
used flags and options are in the General tab.
- As options are editable, save values in registry only when they differ
from the default values. This leaves the registry clean and makes changing
options and their defaults during updates easier.
- Entries for config_dir and log_dir must be absolute paths.
Environemental variables such as %PROFILEDIR% may be used
to construct these.
- Empty config_dir, config_ext and log_dir entries are silently
ignored (i.e., the current values are left unchanged).
- Store all numeric and boolean parameters in registry as DWORD instead of
strings.
- On startup, the default parameters are loaded, then the registry is read
and finally command-line parameters parsedi.
- Out of range script timeout values in registry truncated with a
warning instead of fatal error. This allows the user to access the
settings dialog and make corrections.
- Save proxy and language settings under the same
HKCU\Software\OpenVPN-GUI key as other options instead of under Nilings.
- Save the current version of the GUI in regsitry so that updates
can be detected and any needed registry cleanup done.
- If no version info is present in the registry any values in OpenVPN-GUI
key in HKCU are deleted for a clean start as this is the first version
to save registry values in HKCU. Language and proxy data if present
under Nilings is migrated.
Note: new controls in the General tab and newly added Advanced tab dialog
are copied to all language files from the English version. These need to
be translated.

- Username and, optionally, password as well as the private
key passphrase are saved in config-specific registry keys
- All saved data are kept encrypted using DPAPI
- The passphrase dialog is skipped if a valid saved private
key password is available. However, the user-auth dialog
is always presented, prefilled with the saved username
and password.
Note: A text string "Save password" is added to three dialogs
in all language resource files. Additional text with ids
IDS_MENU_CLEARPASS and IDS_NFO_DELETE_PASS are added to the
STRINGTABLE only in the English language resource file.
All these need translations.

When a connection is attempted using a config in a location
that would fail, offer an option to add the user to the "OpenVPN
Administrators" group. This is done using shell-execute which will
show a UAC prompt for elevation. If it fails (due to user chooses
NO or the UAC dialog fails) the connection is not started.
v2 Changes
- Rebase to master
- Automaticlaly add the admin group if it doesn't exist
- Allow unicode strings in debug output
- Use domain\username to identify user
- Fix the PrintDebug macro
Minor changes based on user feedback
- Bring the window back to foreground after UAC prompt completion
- Show a message if another connection is tried during authorization
- Do not add user to ovpn_admin_group if it is same as the built-in admin group

- Handle early errors (openvpn exits before management connection is up)
with a helpful error message that points the user to view log.
- Include only readable config files in the connection list
- Warn if no connection profiles found
TODO: handle startup errors from interactive service
Change the default log file location to OpenVPN/log in user's profile directory
to support running without admin privileges using the interactive service.
The registry keys are moved to HKCU from HKLM to allow for user-specific
settings as well as to avoid the need for running the GUI as admin at the
first instance.
