|
// File: connection.cpp
|
|
//
|
|
// Module: CMMON32.EXE
|
|
//
|
|
// Synopsis:
|
|
// Implement class CCmConnection
|
|
// CCmConnection manages a single connection.
|
|
//
|
|
// The m_StatusDlg lives through out the CONNECTED/DISCONNECT_COUNTDOWN
|
|
// state. The appearance changes when it comes to COUNTDOWN state.
|
|
//
|
|
// The m_ReconnectDlg is the reconnect prompt dialog. It exist during
|
|
// STATE_PROMPT_RECONNECT state.
|
|
//
|
|
// Both dialogs are modeless. (We need a initially invisible status dialog
|
|
// to receive timer and trayicon message. I did not find any way to create
|
|
// a invisible modal dialog without flashing.)
|
|
//
|
|
// CreateDialog will simply return, unlike DialogBox, which returns only after
|
|
// Dialog is ended. To simplify the implementation, we handle end-dialog event
|
|
// in the thread routine instead of in the dialog procedure.
|
|
//
|
|
// When we need to end the status or reconnect dialog, we simply post a thread
|
|
// message to end the dialog and continue to the next state. The connection
|
|
// thread runs a message loop and processes thread message.
|
|
//
|
|
// The RasMonitorDlg on NT is running in another thread. Otherwise the connection
|
|
// thread message can not be processed
|
|
//
|
|
// The connection is event driven module. ConnectionThread() is the entry
|
|
// point of the connection thread.
