RE: [Mono-list] Problem with xml.Serialization
Hi,
I see another problem here. It is not an good idea to derive from ArrayList,
because the XmlSerializer has special handling for ArrayList and also
classes that derive from it. Instead you should Package the ArrayList indo
another class (this may be for example a custom collection type).
The second thing you need to do is to tell the serializer if there are any
instances of custom objets, that you are inserting into the ArrayList. This
is done by the XmlInclude attribute.
Try this example:
using System;
using System.Collections;
using System.IO;
using System.Xml.Serialization;
using System.Text;
namespace XmlSerializationTest
{
class Program
{
static void Main(string[] args)
{
Subject subject = new Subject();
subject.name = Subject Name;
subject.comment = Subject Comment;
SubjectList subjectList = new SubjectList();
subjectList.subject = subject;
subjectList.list.Add(Test);
subjectList.list.Add(123);
CustomObject co = new CustomObject();
co.customString = Custom String;
subjectList.list.Add(co);
XmlSerializer serializer = new
XmlSerializer(typeof(SubjectList));
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
serializer.Serialize(sw, subjectList);
Console.WriteLine(sb.ToString());
Console.ReadLine();
}
}
[XmlInclude(typeof(CustomObject))]
public class SubjectList
{
public Subject subject;
public ArrayList list;
public SubjectList()
{
list = new ArrayList();
}
}
public class Subject
{
public string name;
public string comment;
}
public class CustomObject
{
public string customString;
}
}

You are assinging an instance of type gorganizer.Subject to a obj
variable of type object. When the serializer tries to serialize this
variable, it finds that this is not an instance of type object but
something it did not expected. So either use the XmlInlude attribude

If I change the list to work with Subject the error is the same.
Could you put me an example of how to say the serializer what I want to
serialize?

RE: [Mono-list] Windows to Linux Remoting problem
Hi! This seems to be an DNS-resolving issue. You provided no source code so i can only guess. When the runtime is marshaling object into another appdomain (from server to client), it creates an ObjRef class wich contains all relevant info to create a proxy (on client) for the marshaled object in the another appdomain. Inside this info is also an uri wich is used when invokig methods on the marshaled object. The problem ist, that this uri is generated on the server. The server uses ist hostname to create this uri. If the hostname can not be roselved on the client machine, then you get an exception when you try to invoke a method on the mashaled object. Example: Client calls new MXSRemoteQuote.QuoteProviderController(...) (the remoting knows that this is a client activated type, so it sends a request to the url from your client config file) Server creates an instance of MXSRemoteQuote.QuoteProviderController, generates an ObjRef for it (with unique uri for the marshaled instance, part of this uri ist the hostname eg server-xyz) and send is as response to the client Client creates a proxy object from the ObjRef received from the server Client tryes to invoke a method on the proxy class, wich causes the remoting to try to send a request to the server, but this fails, because the hostname part of the uri (server-xyz) can not be resolved on the client I hope this helps you to resolve your problem Robert -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Zbigniew Babiej Sent: Donnerstag, 07.

Hello,
I'm resending this email, this time with a sample that actually reproduces
the problem - I checked it in both MS .NET and mono 1.1.1.0.
Sorry for the previous one.
Considering that the previous sample actually compiles and run in MS .NET,
now I'm thinking it's a bug in csc... anyway, I'd like to read your
comments, and if a mono hacker considers it's a mono bug, I can file a bug
report.
Here goes the testcase; it doesn't compile on Windows, but it does on mono
(if you run it, you'll get a NullReferenceException but that's ok):
compiled with:
Microsoft (R) Visual C# .NET Compiler version 7.00.9951 for Microsoft (R)
.NET Framework version 1.0.3705
The error is in the line that contains the 'foreach' statement:
The call is ambiguous between the following methods or
properties: 'Testing.ICustomEnumerable.GetEnumerator()'
and 'System.Collections.IEnumerable.GetEnumerator()'

The problem is that this same piece of code won't compile in MS.NET csc

simplified example): it complains that it can't choose between
System.Collections.IEnumerable and IMyEnumerable.
I'm rising this question because I'm not sure if this is a mono or a MS
.NET bug, because I find the spec (ECMA-334, 15.8.4) rather ambiguous.
At a given point it reads:
A type C is said to be a collection type if it implements
the System.IEnumerable interface or implements the collection

The thing is that it's not specified what happens when _both_ criteria
are met.
So, what do you think?

RE: [Mono-list] Can't open a StreamWritter with a file created by File.Create
Hi,
It doesn't work, because File.Create(test-file) creates a new file and
returns an FileStream object, wich holds the handle for the file. You do not
assing this object anywhere, so it is a candidate for the garbage
collection. Until the GC disposes this object (this can take some time),
wich releases the allocated file handle, the file is still opened. So if
your next statement tryes to access this file, you get an sharing violation.
You should always call Close() to release the underlying file handle.
Solution 1.:
FileStream s = File.Create(test-file);
s.Close();
StreamWriter sw = new StreamWriter(test-file);
//do some work
sw.Close();
Solution 2 (more elegant):
using(StreamWriter sw = new StreamWriter(File.Create(test-file))) {
//do some work
}

Subject: [Mono-list] Can't open a StreamWritter with a file created by
File.Create
Hi,
With the mono beta 2 I'm not able to create a file with File.Create and
then, open a StreamWritter on it.
For example a simple program like this throws the error Unhandled
Exception: System.IO.IOException: Win32 IO returned ERROR_SHARING_VIOLATION.
Path: test-file everytime I run it :
using System;
using System.IO;
namespace Test {
public class test {
public test()
{
File.Create(test-file);
StreamWriter sw = new StreamWriter(test-file);
}
static void Main (string[] args)
{
new test();
}
}
}
But this kind of operation works perfectly on mono beta 1.
So I would like to know if this bug is a regression (what regression !!) or
just a bizzarery of my computer.
Accordingly, I would be grateful if someone could run the little program
above and tell me if he has the same result.
In this case I'll open a bug on bugzilla, and in the other case any help
would be appreciated :)
Thanks in advance

Re: [Mono-list] A Plugin and WebService Issue
Hi, I would use this approach: 1) you must have a plug-in Interface defined, that each plug-in must implement 2) when the application starts, use static System.IO.Directory.GetFiles() method to get the names of assemblies in the plug-in directory 3) for each plug-in-assembly file call static System.Reflection.Assembly.LoadFrom() method to load the assembly into the current AppDomain, then call the method System.Reflection.Assembly.GetTypes() on the System.Reflection.Assembly instance that you've got from the previous LoadFrom() method 4) for each Type that you get from previous GetType() method use the is operator to check if the particular type implements the plug-in interface, if it does, you have a type that implements your plug-in interface. 5) call static Syste.Activator.CreateInstance() method with the type from previous step as parameter. Cast the result to the plug-in-interface type and store it for example in an array for later use. 6) now you have an array of plug-in instances and can call the interface methods on them This is just an example, there are several other approaches which are more or less similar to this one... everything depends on the needs of your application. RoBiK Quoting Pablo Fischer [EMAIL PROTECTED]: Hi! I would like to have some comments and suggestions about a issue. I am working in a Blog Client (mbloggy) that will work ONLY in SOAP (NO XMLRPC) for different CMS and Blogs (phpnuke, postnuke, jaws, etc, etc). To work with all these blogs I'm planning to use a 'plugin' system, based in assemblies, for example: If a developer wants the plugin for a CMS (like drupal), he can save his .dll plugin in ~./mbloggy/plugins and when mbloggy starts it will read default plugins (in /etc/mbloggy) and the user plugins. When mbloggy finds a new plugin it will be added to a 'drop down' (gtk#) so the user can use it. My problem?, yes, I don't know which is the best option: a) Use .dll assemblies as plugins. But, how to connect to each plugin from the front end?, exists a data type that can 'clone' another object?, so I can do something like this: Wrapper wrap = new Wrapper(); wrap.Clone(assemblie.dll); wrap.Url = http://www.foo.bar.com/foo.aspx?wsdl; wrap.DeletePost(3); So I can use the 'methods' of assemblie.dll in the wrap object?. b) Or use just one .dll and let the developers to 'develop' just the WebService (server)?, So I can just work like this: Client c = new Client(); c.Url = http://www.foo.bar.com/foo.aspx?wsdl; c.DeletePost(3); Which is the best option? and where can I find more information for the best option?.

[Mono-list] AppDomain problems
Hi, i try to use an AppDomain, but have serious problems. I'm using RH9
wirt mono beta 1 instaleld from the rpms.
Test program:
using System;
class Test : MarshalByRefObject
{
public void DoTest()
{
Console.WriteLine(DoTest());
}
}
class MainClass
{
public static void Main(string[] args)
{
AppDomain ad = AppDomain.CreateDomain(Test);
Test t = (Test)ad.CreateInstanceAndUnwrap(AppDomainTest, Test);
t.DoTest();
t = null;
AppDomain.Unload(ad);
}
}
Output:
DoTest()

Is this a serious bug or am i missing something?
The second (not so big) problem is the setting of private paths for the
AppDomain. I use AppDomainSetup.PrivateBinPath property to set the value
before i create the domain. It works fine, when using single search
path, but when i try to use semicolon separated list of paths, AppDomain
treats this as single path instead of parsing this string to get the
list.
see the documentation from MS:
http://msdn.microsoft.com/library/en-us/cpref/html/frlrfsystemappdomainsetupclassprivatebinpathtopic.asp
The workaround is to create the appdomain and then use the
AppendPrivatePath method.

RE: [Mono-list] A couple of Remoting Questions
Hi,
1) You do not need a configuration file, but you must somehow configure the
remoting inside your application. You have two options:
- Call RemotingConfiguration.Configure(). You can use null as the filename
parameter. Passing a null reference as the filename parameter will cause
default remoting initialization without requiring the existence of a
configuration file.
Example: RemotingConfiguration.Configure(null);
- Call at least ChannelServices.RegisterChannel() passing as a parameter an
instance of channel class (in your case HttpChannel Class). You do not need
to define the port on the client side.
Example: ChannelServices.RegisterChannel(new HttpChannel());
2) I have RH9 with mono beta 1 installed. I have run your app for about 30
times (and also my own apps many times in past), but never seen such a
strange behavior... Everything works nice and clean, no asserts, no left
behind processes. I have no idea what's wrong.
3) Here ist the soap specification http://www.w3.org/TR/soap/ and here
http://msdn.microsoft.com/library/en-us/dnsoap/html/understandsoap.asp an
article from microsoft regarding soap (with good examples). For monitoring
purpouses you can find a couple of http and/or soap sniffers to use. You can
also code a simple port forwarder wich copies the messages to the console to
watch the trafic.

I have been playing around with remoting and a couple of things have come up
I am trying a test based in the example in MS SDK:

using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;
namespace RemotingTest
{
public class Client
{
public static void Main(string [] args)

(HelloServer)Activator.GetObject(typeof(RemotingTest.HelloServer),
http://localhost:8085/Hello;);
if (obj == null)
{
System.Console.WriteLine(Could not locate server);
}
else
{
string name = blah;
if ( args.Length 0 )
{
name = args[0];
}
Console.WriteLine(obj.Hello(name));
}
}
}
}
Server:
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;
namespace RemotingTest
{
public class Server
{
public static void Main(string [] args) {
HttpChannel chan = new HttpChannel(8085);
ChannelServices.RegisterChannel(chan);
RemotingConfiguration.RegisterWellKnownServiceType(Type.GetType(RemotingTes
t.HelloServer,Object), Hello, WellKnownObjectMode.SingleCall);
System.Console.WriteLine(Hit enter to exit...);
System.Console.ReadLine();
}
}
}
Test Class:
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;
using System.Reflection;
namespace RemotingTest
{
public class HelloServer : MarshalByRefObject
{
public HelloServer()
{
Console.WriteLine(this.ToString() + activated);
}
public String Hello(String name)
{
Console.WriteLine(HelloServer.Hello : {0}, name);
return String.Format(Hi there {0}, name);
}
}
}
Firstly, unlike using the MS.NET SDK it will not work unless one loads the
configuration like:
configuration
system.runtime.remoting
application
client
/client
channels
channel
ref=http
port=0
/
/channels
/application
/system.runtime.remoting
/configuration
I was wondering why the difference in behaviour - does windows have the http
channels already registered in some default configuration which mono doesn't
have or is there a difference in behaviour of
ChannelServices.RegisterChannel() in the mono library - I notice that the
registered channels are stored in a static array in the ChannelServices
class so it strikes me that another program is not going to have access to
this - or am I missing something here? It would be nice to have an example
that worked the same with both mono and the MS SDK.
Secondly I am getting weird intermittent behaviour from both server and
client code - every once in a while I am getting:
** (process:5787): ERROR (recursed) **: file class.c: line 1272
(mono_class_init): assertion failed: (class) aborting...
from the client code, which appears to hang afterwards - the server however
behaves as expected. I am unable to reproduce this at will however.
I also am occasionally getting:
** (server.exe:12805): WARNING **: : unref on 38 called when ref was already
0
From the server after the remote method has been called - again this is
intermittent and not reproducible at will.

RE: [Mono-list] Socket.Select problem
Hi!
It seems to me, that you don't fully understand the concept of select/poll.
The behavior that you describe is correct fo select poll.
For your app, you should use poll, because you are working with single
socket. Use select only if you need to work with multiple socket
simultaneous.
Try this:
public string GetMessage(int timeOut, Socket socket)
{
string s = string.Empty;
while(socket.Poll(timeOut, SelectMode.SelectRead))
{
byte[] buffer = new byte[1];
int count = socket.Receive(buffer, 1,
SocketFlags.None);
if(count == 0)
{
//connection closed
return string.Empty;
}
else
{
char c = (char)buffer[0];
if(c == '\n')
{
//end of line received
return s;
}
s += c;
}
}
//timeout
return string.Empty;
}
Here is the MSDN documentation for Socket.Poll:

Subject: [Mono-list] Socket.Select problem
Hi!!
This is probably not mono-devel related but I'd really appreciate it, if
somebody could help.
I am writing a client application (w/ mono and C#) that communicates with
the server via message-strings. These strings are terminated by the usual
'\n'. The '\n' may be followed by additional data, which is why the string
has to be processed before reading the rest.
I am currently getting one character at a time, checking the socket-state
with Socket.Select. Yes, using a buffer would be nice, but the
server-protocol forces me to do it this way. ;-)
Somehow Select (and Poll, which I have also tried) does not seem to work
correctly. Sometimes I get correct results, mostly nothing is read though.
When using a buffer, everything works rather fine. When using -1 as timeout
value, everything works fine but blocks after the last char.
This is my code:
Select
ArrayList listenList = new ArrayList();
listenList.Add(socket);
int count = 0;
bool read = true;
while (read)
{
read = false;
Socket.Select(listenList, null, null, 5000);
if (listenList.Contains(socket))
{
read = true;
count = socket.Receive(buffer, 1, SocketFlags.None);
Console.WriteLine(count: + count);
message += (char)buffer[0];
if ((char)buffer[0] == '\n')
return message;
}
}
Poll
while (socket.Poll(-1, SelectMode.SelectRead)) {
count = socket.Receive(buffer, 1, SocketFlags.None);
message += (char)buffer[0];
if ((char)buffer[0] == '\n')
return message;
}
Thanks for reading!

[Mono-list] c# written daemon, System.ServiceProcess, posix signals handling...
Hi! I need to write an application in c#, wich should run in background and be able to shut down gracefully when required. The best solution would be to use the System.ServiceProcess namespace, but this namespace is not implemented in mono. I know that there were some discussion about this topic in summer 2003, but since i found nothing. Is there something new in this direction? The other way (not so nice, but would also do the job) would be the catching of posix signals (SIGINT, SIGTERM...) but i have no idea how to do thin in an mono application. The last solution is to use some selfmade communication mechnism, to comunicate with the process and initiate the shutdow - maybe using remoting or some simpler mechanism. Can someone give me some infos or ideas for the solution? Thanx Robert ___ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list
RE: [Mono-list] c# written daemon, System.ServiceProcess, posix signals handling...
Hi Fawad, Thank you for your answer. Even if I use runit, there is still the problem, that I can't catch a signal inside the managed code. I have found also this article (http://lists.ximian.com/archives/public/mono-list/2003-March/012826.html), but this guy has the same problem and no solution. Can you help me and show me how should the code look like? Thank you Robert -Original Message- From: Fawad Halim [mailto:[EMAIL PROTECTED] Sent: Freitag, 16.

Hi Robert, I'd suggest running your app under runit (http://smarden.org/runit/). That'll take care of making sure the app is always running even when killed abnormally. When you 'down' the service in runit, it sends it a SIGTERM and maintains an internal flag that the service is supposed to be down intentionally. There is a thread on signal handlers in the March '03 archive of mono-list, including an example of a sigterm handler using unmanaged calls. -fawad RoBiK wrote: Hi!
