The article explains how to log in.
Implement the IO2GSessionStatus interface in a status listener class:
public class MySessionStatusListener : IO2GSessionStatus{ ... }
Create a session:
O2GSession mSession = O2GTransport.createSession();
Create an object of a status listener class:
MySessionStatusListener statusListener = new MySessionStatusListener(...);
Subscribe the status listener object to the session status. It is important to subscribe before the login:
mSession.subscribeSessionStatus(statusListener);
Log in using the user ID, password, URL, and connection:
mSession.login("userID", "password", "http://www.fxcorporate.com/Hosts.jsp", "Demo");
If you have more than one trading sessions or a pin is required for login, you have to catch the event
TradingSessionRequested in the
onSessionStatusChanged
function of your status listener.
In this case get O2GSessionDescriptorCollection:
O2GSessionDescriptorCollection descs = mSession.getTradingSessionDescriptors();
Then process elements of this collection:
foreach (O2GSessionDescriptor desc in descs){...}
Finally set a trading session using the session Id and pin:
mSession.setTradingSession("sessionID", "pin");
Use the status listener onSessionStatusChanged
function to capture the Connected event:
Log out when you are done:
mSession.logout();
Use the status listener onSessionStatusChanged
function to capture the Disconnected event:
Unsubscribe the session from the status listener:
mSession.unsubscribeSessionStatus(statusListener);
Dispose the session object:
mSession.Dispose();
Login and logout example: [hide]
