Re: [Mono-dev] serialization of structured data in ArrayList
when i compile the code below and i run it, i've got the following
exception:
Unhandled Exception: System.InvalidOperationException: The type Car was
not expected. Use the XmlInclude or SoapInclude attribute to specify
types that are not known statically.
can you help me, how can i solve it? how to serialize the non primitive
type (ArrayList with the instances of the Car class)?
thanks

Re: [Mono-dev] serialization of structured data in ArrayList
I never tried to serialize an ArrayList, but I think you had better to
serialize a strongly typed array of Car objects. An ArrayList is a too
complex structure. If you need an ArrayList on both sides of serialization,
you can use the constructor of ArrayList that takes an ICollection. Arrays
are ICollections so you can pass the received Car[] to the ArrayList
constructor.

Re: [Mono-dev] serialization of structured data in ArrayList
wow - great - it works. thanks a lot :-))
yes - the exception told me what to do, i just didnt know how to use
xmlinclude.
thanks one more time ;)
maybe - two questions:
1. it is good to use xml serialization or binary? as i read the
articles, the binary is faster, but maybe not so usefull when need to
change the configuration file by my own.
2. in this case (of this example code) - is it better to use structure
Car or class Car?

We'll need a default constructor if we don't implement ISerializable.
public Car( string type, int price )
{
this.type = type;
this.price = price;
}
}
We gotta know our Car type.
[Serializable]
[XmlInclude(typeof(Car))]
public class Config
{
static string filename = .configrc;

The error message of the Exception told you :)

[Mono-dev] mod_mono on Windows
Hello Gonzalo, As we talked earlier, I'm sending you the patches for mod_mono on windows. On patch mod_mono-win32-3, const int MAXARGS = 21; should work using #define , but on Windows, as const int it does not work, so for now it is hardcoded. I think the best should be testing with define. I have discussed it with Algel Marin (the patch creator) and there should be no problem on using define. There are a few issues we should discuss also: * If the autohosting is used, mod-mono-server does not identify paths as applications (maybe we didn't figure out how to make it work) * We need to determine also a good LISTEN_PORT value * With some releases you can configure the directives with spaces and backslashes and then in the next one the behavior changes, the directive that accepted spaces, makes mono fail and the one that gave problems starts accepting them, for example on 1.1.10 MonoDocumentRootDir does not work if you configure it with a path that has spaces, mono gives exceptions until you use the old 8.3 format for the path. On 1.1.9 MonoExecutablePath gave similar problems, but in 1.1.10 it works. (on a first impression I would say it could be some platform path mapping glitch on the base classlib) * The build process on windows depends on cygwin (win32 glib builds) * fork_mod_mono_server does two different tasks: first it prepares the arguments to launch mod-mono-server.exe, then It setups the environment needed for the fork and forks the process. The arguments needed for win32 are just the same needed for linux, just the fork stuff changes. To ease maintenance the args should be setup in other function and #ifdef WIN32 should be used to declare the right function. The patch mod_mono-win32-3 handles fork_mod_mono on windows ... it should be rewritten as stated earlier. The patches were designed in a manner to keed mod_mono the closest from original. There could be some corrections in order to merge it with the actual code and keed it portable. If there is no problem, me and Angel Marin could do the refactoring as stated on this mail and I could commit it later. -- Regards, Alexandre Rocha Lima e Marcondes P4 Tecnologia e Desenvolvimento Humano [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] www.p4tecnologia.com alexandre.p4tecnologia.com Projetos: MonoBrasil MonoBASIC ACBr Freedom ERP To validate this message's signature follow the instructions: http://www.cacert.org/index.php?id=3lang=en_US smime.p7s Description: S/MIME cryptographic signature ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

I believe that that library is in /usr/ucblib and is there by default (I don't know that for sure, since we have Workshop installed).

This isn't a regression. Thread.Interrupt never worked in mono,
however, in older versions,
it did nothing, causing code using it to silently fail, now it throws
