What I want to do is call a function in my main form/class from the
server (which the another program/client calls). The main form does
not really create a server object so I can't pass the frmForm class
into the constructor of MyServer (the client side would have no idea
what to pass into that anyways). What other way to do this is there?
I guess there is static functions, but I can't make everything in
those functions static.
namespace Mark
{
public class frmForm : System.Windows. Forms.Form
{
private void frmForm_Load(ob ject sender, System.EventArg s e)
{
HttpChannel channel = new HttpChannel(800 1); //Create a new
channel
ChannelServices .RegisterChanne l (channel); //Register channel
RemotingConfigu ration.Register WellKnownServic eType(typeof (MyServer),"MyS erver",WellKnow nObjectMode.Sin gleton);
}
public void Function1()
{
//do some non-static stuff here
}
}
public class MyServer: MarshalByRefObj ect
{
public void CalledByClient( )
{
//want to call frmForm.Functio n1 here
}
}
} 5 3974
Well MyServer is a singleton how about getting the form to achieve the same
effect by manually marshallingobje ct into the remoting infrastructure.
instead of using RegisterWellKno wnServicetype, create an instance of
MyServer pass itself into the ctor and then call
RemotingService s.Marshal passing the instance.
Its proably a good idea in this case to override InitializeLifet imeServices
in MyServer and return null. This will disable the lease based distributed
garbage collection of remoting which in this case is probably a good idea.

So would I do something like?
MyServer svr = new MyServer();
svr.PassFormOve r(this);
ObjRef objrefWellKnown = RemotingService s.Marshal(svr, ???????);
What do I put for the other arguments?
I would of course put something like
public class MyServer: MarshalByRefObj ect
{
static public Mark.frmForm frmMyForm;
public void PassFormOver(Ma rk.frmForm frm)
{
frmMyForm = frm;
}
public void CalledByClient( )
{
//want to call frmForm.Functio n1 here
}
}
}
HttpChannel channel = new HttpChannel(800 1);
MyServer ms = new MyServer(this);
RemotingService s.Marshal(ms, "MyServer") ;
ChannelServices .RegisterChanne l (channel); //Register channel
you basically provide the same info as with RegisterWellKno wnServiceType but
*you* create the instance rather than the remoting infrastructure. And as
you can see I'd probably create a ctor on MyServer which took an instance of
your form.

That seems to work. Thanks. One more question though. How does it
know it's a singleton? Sorry if it's a rookie question but this is my
first time working with remoting. Does it also already know it's a
WellKnownServic eType?
