Méthodes publiques

Méthode	Description
Authenticate ( string password ) : bool	Use a password to authenticate with a VNC Host. NOTE: This is only necessary if Connect() returns TRUE.
Connect ( string host ) : bool	Connect to a VNC Host and determine which type of Authentication it uses. If the host uses Password Authentication, a call to Authenticate() will be required. Default Display and Port numbers are used.
Connect ( string host, int display ) : bool	Connect to a VNC Host and determine which type of Authentication it uses. If the host uses Password Authentication, a call to Authenticate() will be required. The Port number is calculated based on the Display.
Connect ( string host, int display, int port ) : bool
Connect ( string host, int display, int port, bool viewOnly ) : bool	Connect to a VNC Host and determine which type of Authentication it uses. If the host uses Password Authentication, a call to Authenticate() will be required.
Disconnect ( ) : void	Stops sending requests for updates and disconnects from the remote host. You must call Connect() again if you wish to re-establish a connection.
Initialize ( ) : void	Finish setting-up protocol with VNC Host. Should be called after Connect and Authenticate (if password required).
Listen ( string host, int port, bool viewOnly ) : void	Wait for a connection from VNC Server.
RequestScreenUpdate ( bool refreshFullScreen ) : void	Requests that the remote host send a screen update. RequestScreenUpdate needs to be called whenever the client screen needs to be updated to reflect the state of the remote desktop. Typically you only need to have a particular region of the screen updated and can still use the rest of the pixels on the client-side (i.e., when moving the mouse pointer, only the area around the pointer changes). Therefore, you should almost always set refreshFullScreen to FALSE. If the client-side image becomes corrupted, call RequestScreenUpdate with refreshFullScreen set to TRUE to get the complete image sent again.
SetInputMode ( bool viewOnly ) : void	Changes the input mode to view-only or interactive.
StartUpdates ( ) : void	Begin getting updates from the VNC Server. This will continue until StopUpdates() is called. NOTE: this must be called after Connect().
StopListen ( ) : void
VncClient ( ) : System
WriteClientCutText ( string text ) : void
WriteKeyboardEvent ( uint keysym, bool pressed ) : void
WritePointerEvent ( byte buttonMask, Point point ) : void

Method Details

Authenticate() public méthode

Use a password to authenticate with a VNC Host. NOTE: This is only necessary if Connect() returns TRUE.

public Authenticate ( string password ) : bool
password	string	The password to use.
Résultat	bool

Connect() public méthode

Connect to a VNC Host and determine which type of Authentication it uses. If the host uses Password Authentication, a call to Authenticate() will be required. Default Display and Port numbers are used.

public Connect ( string host ) : bool
host	string	The IP Address or Host Name of the VNC Host.
Résultat	bool

Connect() public méthode

Connect to a VNC Host and determine which type of Authentication it uses. If the host uses Password Authentication, a call to Authenticate() will be required. The Port number is calculated based on the Display.

public Connect ( string host, int display ) : bool
host	string	The IP Address or Host Name of the VNC Host.
display	int	The Display number (used on Unix hosts).
Résultat	bool

Connect() public méthode

public Connect ( string host, int display, int port ) : bool
host	string
display	int
port	int
Résultat	bool

Connect() public méthode

Connect to a VNC Host and determine which type of Authentication it uses. If the host uses Password Authentication, a call to Authenticate() will be required.

public Connect ( string host, int display, int port, bool viewOnly ) : bool
