[Mono-list] .net remoting problem with object sending

[Axel Westerhold]

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;
            }

Regards, 
Axel
