Hello,
according to the spec (25.2), you can only take a pointer of an
unmanaged type, not a managed one.

I'll fix gmcs to report the same error.

[Mono-list] casting reference arguments
I've found another case where the compiler should give a different error (at
the moment it crashes).
public class Test {
public static void Main ()
{
byte b = 8;
int i = 256;
Increment (ref b);
System.Console.WriteLine ("8 + 1 = {0}", b);
Increment (ref i);
System.Console.WriteLine ("256 + 1 = {0}", i);
}
public static void Increment (ref int arg)
{
arg += 1;
}
public static void Increment (ref byte arg)
{
// reference cast - not allowed
Increment (ref (int) arg);
}
}
Who needs specifications to test against when you have a twisted mind?
Seriouslly though, the above code could be legal - mcs might be expected to
create a temporary variable of type int, assign the byte value to it, call
the other Increment overload with it, and then assign its value back to the
byte argument - so a check against the microsoft compiler is necessary.

[Mono-list] mod_mono sharing application session data

Re: [Mono-list] mod_mono sharing application session data
Aren't HttpSessions "keyed" to the Session IDs they set? In any event, web applications traditionally operate in a disconnected state because this is how web servers operate. One HTTP request has nothing to do with another. You need to consider very carefully the idea of trying to make a web app that goes against this. If you really need a very tightly tied together system then the web isn't a good platform. Or are you asking more of a single sign on question? What is in the HttpSession that you need to share?

Re: [Mono-list] mod_mono sharing application session data
Hi, One secure solution would be doing custom digest authentication in an IHttpModule which is then valid for the various applications. The authentication module could then be shared by all applications and maybe rather than a flat file you could use a DB or LDAP for the back end. ;-) In addition, you could fall back to BASIC authentication if the digest is not supported (though I think all modern browsers support it nowadays). I did something like this a while back and though it was not for multiple apps, I think if you used the same 'realm' (see the spec.) for all your applications then it should work. There are a number of sample on how to do this in .NET out there.

The problem is that if I travel from one directory to another and check session its missing, because HttpSession seems to be directory/application specific. This is very annoying. Suppose you have an application (as I will soon) where you have a Core module that supplies users, roles, etc and a login. From there you would travel to other modules which would of course need to know that your logged in (a cookie works - FormsAuthentication class). But suppose I set your Member object into Session within the Core module, the Foo module could not access it. So in fact I would have to check your cookie and retrieve again the Member object associated to that cookie from the database. Thus, an unecessary call to the database, and two instances of the same object sitting in session. Its a data integrity nightmare! Any ideas, suggestions solutions? ~ Matthew P.S.

Having a site made up of several subdirectories doesn't mean it's a bad program to use the web as a platform. Certainly sessions should span directories when it's the same web app. IIS certainly treats it that way. I unfortunately can't help though, as I have not done any work with sessions on Mono yet.

It seems that the following structure of directories will share session information. / - application login /core /foo /bar But I was doing the following, which definitely did NOT work. /public - application login /core /foo /bar This does make sense - but the lack of documentation about any of this is extremely annoying. No where is this stated that I could find. But having thought about it, and related it to the way Web.config files load it makes perfect sense. Any ways, BLAH.

[Mono-list] Mono with MySQL; Glade and Menubar
Two questions if I may: 1. I have set up a simple application using MonoDevelop (Mono 1.0, most recent versions of everything according to Red Carpet) to access data in a local MySQL database. When compiled in MonoDevelop I get messages about not finding the necessary assemblies for accessing mysql, however in a command line interface specifying the libraries with -r params the programme compiles and runs just fine. Am I missing some kind of directive in MonoDevelop that would allow it to find System.Data and ByteFX.Data? 2. In another application I have a simple glade window with one button working fine, however if I add a menubar to the window I get a lot of warnings about "Unknown property stock_item in class GtkImageMenuItem" followed by other errors. Does this mean that some elements in the GTK+ bag of goodies are currently supported, and others not, or am I missing another specification?

[Mono-list] Any interest in a new open source project?
I have a project I call Safari Cell, for now, that takes a relational SQL database and turns it into a DataSet with DataTables for every table, complete with DataRelations, UniqueConstraints, ForeignKeyConstraints and a few other handy things. All the Data… objects are hidden, however, behind classes that manage filling those entities with data from the database on an as-called-for basis. Modified data is cached and written later by a lazy-writer thread. Unused data is eventually removed from the cache. Any modified column is validated against any extra schema available from the DB server. The goal is to make it really easy to write business objects that operate on relational databases, to take advantage of fast caching, transactions, and all without writing any plumbing code in the business object itself. Safari Cell scans the database schema at startup and exposes everything through typed classes. I have done a great deal of work on this project, all in Visual Studio .NET in C#. I want to make it open source so that others can help add code to support other DB servers besides just MS SQL Server. I started the project with extensibility and multiple database server backends in mind. Is there a great deal of interest in helping these classes grow and mature? I am planning on putting the source up on Novell’s sourceforge if people are willing to use/contribute. - Andrew Arnott
