Re: [Mono-list] .net remoting problem with object sending
Hi there, I am a little guessing here but it sounds as if you would using XML/SOAP/WEB kind of remoting. In this case make sure each and every variable in your object/class/struct is defined and initialized. You can also switch to a binary formater which will solve this issue too but will break access through proxy.

Re: [Mono-list] .net remoting problem with object sending
Hi there,
Don't get me wrong. You can use a binary formater AND an HTTP channel.
Like this
Server
HttpChannel hc;
BinaryServerFormatterSinkProvider sbf = new
BinaryServerFormatterSinkProvider();
BinaryClientFormatterSinkProvider cbf = new
BinaryClientFormatterSinkProvider();
IDictionary properties = new Hashtable();
properties[port] = port;
if( !fqdn.Equals() ){
properties[machineName] = fqdn;
}
else{
Helper.ErrorLog(ManageMail DB Provider using IP as no fqdn found);
}
hc=new HttpChannel(properties,cbf,sbf);
ChannelServices.RegisterChannel(hc,false);
RemotingConfiguration.ApplicationName=DBAbstract;
RemotingConfiguration.RegisterActivatedServiceType(typeof(DBAbstract));
Client
try{
BinaryServerFormatterSinkProvider sbf = new
BinaryServerFormatterSinkProvider();
BinaryClientFormatterSinkProvider cbf = new
BinaryClientFormatterSinkProvider();
IDictionary properties = new Hashtable();
properties[name] = ManageMail LogViewer;
ChannelServices.RegisterChannel(new HttpChannel(properties,cbf,sbf),false);
RemotingConfiguration.RegisterActivatedClientType(typeof(DBAbstract),dbInfo.
GetRemotingString());
}
catch{
Application.Exit();
return;
}

Re: [Mono-list] .net remoting problem with object sending
One more comment,
I used XML formating but hit a brickwall because while all my entities were
properly defiend and initialized some Framework components were not. As soon
as the XML Formater found a Null within a collection, object or class it
stopped working. Since I use the binary formater my problems are gone and it
seems to work very stable (loading 100.000,00 records in one run and loading
new records in 5 sec. Intervals für 12 hours. It behaves well in my threaded
eviroment and while the server runs on Linux the client is on windows.
