Hey Bjarne!
First, you should probably avoid using the built in library palette
behaviors until you get your feet more wet with the Multiuser Xtra. While
they are excellent, self-contained modules of code there are some tricky
aspects to building additional code which utilizes the connections that
they create.
Here's a simple model to consider using:
1) Make an instance of the Xtra and begin an attempt to connect to a SMU
server:
global gClientConnection
on initClient
gClientConnection = new( xtra "Multiuser" )
if objectP( gClientConnection ) then
-- establish the buffers needed
gClientConnection.setNetBufferLimits(1024 * 4, 1024 * 4, 5)
-- set up our default message
gClientConnection.setNetMessageHandler( #muMessage, 0, 0, 0, TRUE )
-- filter for connection to server results
gClientConnection.setNetMessageHandler( #logonToHost, 0,
"ConnectToNetServer", 0, TRUE )
-- create a timeout object to process connections
errCode = gClientConnection.connectToNetServer("host.yourdomain.com,
1626, [#userID : "yourNameHere", #password : "password", #movieID :
"yourMovieIDHere"], #smus, "encryptionKey")
testForError errCode
else
alert "Couldn't make an instance of the Multiuser Xtra!"
end if
end initClient
-- this tests for any Multiuser Xtra error that occurs
on testForError errorCode
if ( errorCode <> 0 ) then
showStatus #alert, "MU ERROR:" && gClientConnection.getNetErrorString(
errorCode )
end if
end testForError
2) Wait for a response by looping on a frame or doing something similar.
NOT in a repeat loop.
3) When you receive a notification message, determine what to do next:
-- this generically handles any incoming messages not otherwise trapped
on muMessage me, newMessage
testForError newMessage.errorCode
alert "UNEXPECTED Message Received by Pager:" && string( newMessage )
end muMessage
-- check to see if we are able to connect as a client
on logonToHost me, newMessage
testForError newMessage.errorCode
if newMessage.errorCode = 0 then
alert "Connected to Host!"
-- now implemented your next course of action
-- such as sending a database message
-- implement setNetMessageHandler filters as needed to manage
-- incoming messages indication completion status for your database actions
else
alert "Connection to Host attempt failed."
end if
end logonToHost
HTH,
Terry
