12 \section{\class{wxDialUpManager}}\label{wxdialupmanager}
13
14 This class encapsulates functions dealing with verifying the connection status
15 of the workstation (connected to the Internet via a direct connection,
16 connected through a modem or not connected at all) and to establish this
17 connection if possible/required (i.e. in the case of the modem).
18
19 The program may also wish to be notified about the change in the connection
20 status (for example, to perform some action when the user connects to the
21 network the next time or, on the contrary, to stop receiving data from the net
22 when the user hangs up the modem). For this, you need to use one of the event
23 macros described below.
24
25 This class is different from other wxWidgets classes in that there is at most
26 one instance of this class in the program accessed via
27 \helpref{wxDialUpManager::Create()}{wxdialupmanagercreate} and you can't
28 create the objects of this class directly.

39
40 To be notified about the change in the network connection status, use these
41 event handler macros to direct input to member functions that take a
42 \helpref{wxDialUpEvent}{wxdialupevent} argument.

57 \membersection{wxDialUpManager::Create}\label{wxdialupmanagercreate}
58
59 \func{wxDialUpManager*}{Create}{\void}
60
61 This function should create and return the object of the platform-specific
62 class derived from wxDialUpManager. You should delete the pointer when you are
63 done with it.
64
65 \membersection{wxDialUpManager::IsOk}\label{wxdialupmanagerisok}
66
67 \constfunc{bool}{IsOk}{\void}
68
69 Returns {\tt true} if the dialup manager was initialized correctly. If this
70 function returns {\tt false}, no other functions will work neither, so it is a
71 good idea to call this function and check its result before calling any other
72 wxDialUpManager methods
73
74 \membersection{wxDialUpManager::\destruct{wxDialUpManager}}\label{wxdialupmanagerdtor}
75
76 \func{}{\destruct{wxDialUpManager}}{\void}
77
78 Destructor.
79
80 \membersection{wxDialUpManager::GetISPNames}\label{wxdialupmanagergetispnames}
81
82 \constfunc{size\_t}{GetISPNames}{\param{wxArrayString\& }{names}}
83
84 This function is only implemented under Windows.
85
86 Fills the array with the names of all possible values for the first
87 parameter to \helpref{Dial()}{wxdialupmanagerdial} on this machine and returns
88 their number (may be $0$).
89
90 \membersection{wxDialUpManager::Dial}\label{wxdialupmanagerdial}
91
92 \func{bool}{Dial}{\param{const wxString\& }{nameOfISP = wxEmptyString}, \param{const wxString\& }{username = wxEmptyString}, \param{const wxString\& }{password = wxEmptyString}, \param{bool }{async = true}}
93
94 Dial the given ISP, use {\it username} and {\it password} to authenticate.
95
96 The parameters are only used under Windows currently, for Unix you should use
97 \helpref{SetConnectCommand}{wxdialupmanagersetconnectcommand} to customize this
98 functions behaviour.
99
100 If no {\it nameOfISP} is given, the function will select the default one
101 (proposing the user to choose among all connections defined on this machine)
102 and if no username and/or password are given, the function will try to do
103 without them, but will ask the user if really needed.
104
105 If {\it async} parameter is {\tt false}, the function waits until the end of dialing
106 and returns {\tt true} upon successful completion.
107
108 If {\it async} is {\tt true}, the function only initiates the connection and
109 returns immediately - the result is reported via events (an event is sent
110 anyhow, but if dialing failed it will be a DISCONNECTED one).
111
112 \membersection{wxDialUpManager::IsDialing}\label{wxdialupmanagerisdialing}
113
114 \constfunc{bool}{IsDialing}{\void}
115
116 Returns true if (async) dialing is in progress.

120 \helpref{Dial}{wxdialupmanagerdial}
121
122 \membersection{wxDialUpManager::CancelDialing}\label{wxdialupmanagercanceldialing}
123
124 \func{bool}{CancelDialing}{\void}
125
126 Cancel dialing the number initiated with \helpref{Dial}{wxdialupmanagerdial}
127 with async parameter equal to {\tt true}.
128
129 Note that this won't result in DISCONNECTED event being sent.

133 \helpref{IsDialing}{wxdialupmanagerisdialing}
134
135 \membersection{wxDialUpManager::HangUp}\label{wxdialupmanagerhangup}
136
137 \func{bool}{HangUp}{\void}
138
139 Hang up the currently active dial up connection.
140
141 \membersection{wxDialUpManager::IsAlwaysOnline}\label{wxdialupmanagerisalwaysonline}
142
143 \constfunc{bool}{IsAlwaysOnline}{\void}
144
145 Returns {\tt true} if the computer has a permanent network connection (i.e. is
146 on a LAN) and so there is no need to use Dial() function to go online.
147
148 {\bf NB:} this functions tries to guess the result and it is not always
149 guaranteed to be correct, so it is better to ask user for
150 confirmation or give him a possibility to override it.
151
152 \membersection{wxDialUpManager::IsOnline}\label{wxdialupmanagerisonline}
153
154 \constfunc{bool}{IsOnline}{\void}
155
156 Returns {\tt true} if the computer is connected to the network: under Windows,
157 this just means that a RAS connection exists, under Unix we check that
158 the "well-known host" (as specified by
159 \helpref{SetWellKnownHost}{wxdialupmanagersetwellknownhost}) is reachable.
160
161 \membersection{wxDialUpManager::SetOnlineStatus}\label{wxdialupmanagersetonlinestatus}
162
163 \func{void}{SetOnlineStatus}{\param{bool }{isOnline = true}}
164
165 Sometimes the built-in logic for determining the online status may fail,
166 so, in general, the user should be allowed to override it. This function
167 allows to forcefully set the online status - whatever our internal
168 algorithm may think about it.
169

172 \helpref{IsOnline}{wxdialupmanagerisonline}
173
174 \membersection{wxDialUpManager::EnableAutoCheckOnlineStatus}\label{wxdialupmanagerenableautocheckonlinestatus}
175
176 \func{bool}{EnableAutoCheckOnlineStatus}{\param{size\_t }{nSeconds = 60}}
177
178 Enable automatic checks for the connection status and sending of
179 {\tt wxEVT\_DIALUP\_CONNECTED/wxEVT\_DIALUP\_DISCONNECTED} events. The interval
180 parameter is only for Unix where we do the check manually and specifies how
181 often should we repeat the check (each minute by default). Under Windows, the
182 notification about the change of connection status is sent by the system and so
183 we don't do any polling and this parameter is ignored.
184
185 Returns {\tt false} if couldn't set up automatic check for online status.
186
187 \membersection{wxDialUpManager::DisableAutoCheckOnlineStatus}\label{wxdialupmanagerdisableautocheckonlinestatus}
188
189 \func{void}{DisableAutoCheckOnlineStatus}{\void}
190
191 Disable automatic check for connection status change - notice that the
192 {\tt wxEVT\_DIALUP\_XXX} events won't be sent any more neither.
193
194 \membersection{wxDialUpManager::SetWellKnownHost}\label{wxdialupmanagersetwellknownhost}
195
196 \func{void}{SetWellKnownHost}{\param{const wxString\& }{hostname}, \param{int }{portno = 80}}
197
198 This method is for Unix only.
199
200 Under Unix, the value of well-known host is used to check whether we're
201 connected to the internet. It is unused under Windows, but this function
202 is always safe to call. The default value is {\tt www.yahoo.com:80}.
203
204 \membersection{wxDialUpManager::SetConnectCommand}\label{wxdialupmanagersetconnectcommand}
205
206 \func{void}{SetConnectCommand}{\param{const wxString\& }{commandDial = wxT("/usr/bin/pon")}, \param{const wxString\& }{commandHangup = wxT("/usr/bin/poff")}}
207
208 This method is for Unix only.
209
210 Sets the commands to start up the network and to hang up again.
