[Mono-list] Hackers with Windows boxes + Perl needed
Hi, I was wondering if anyone on this list had a Windows box + Mono + Perl that could try out my Perl interpreter bindings for C#[1]. Basically I wanted access to all the useful utilities out there on CPAN[2] that aren't yet available in managed code or in the standard class libraries. The distribution gives a sample IMAP client using Mail::IMAPClient. It works on Linux (Gentoo SuSE 9) and seems to work OK on OS X with a little munging of the library names and modulo mono-wierdness wrt exceptions (yes I know about mint...). I'd ideally like it to work on Windows as well, then it could be a truly cross-platform way of getting lots of functionality into C# for 'free'. I've based the build system on Gtk#. For those that just want to look at how easy it is to embed Perl using the powerful features of C# take a look at the IMAP example[3]. C# really does make this nice, a lot nicer than the Perl C API! For example Scalars are auto-boxed to the approriate fundamental types (int, double, string).

[Mono-list] CodeDom testcases/examples
Does anyone know of any simple language-independent CodeDom testcases/examples that could be used to generate some code that a human could then look at and verify? Ideally some examples that start off doing really simple stuff (I guess defining an empty class in a given namespace would qualify), with gradually increasing complexity to eventually cover all the language features that CodeDom can express... If not, could the existing tests in mcs/class/System/Tests/Microsoft.* be used as the basis for starting something like that? Do other people agree that it would be a nice thing to have? As a later feature, I suppose you could test the compilation aspects of CodeDom by compiling the results for each language and using reflection to examine and invoke them. That would give a really nice testsuite for any new language that wants to be CodeDom-capable, and could probably supercede some of the tests in mcs/class/System/Tests altogether (just auto-enumerate all the languages defined in machine.config and run this testsuite against each one).

RE: [Mono-list] System.Exception.Security when mixing mono with microsoft
Ofer, Non local assemblies (e.g. network drives) are given much less freedom than local ones by the MS runtime. Some ressources (like DNS) requires specific permissions (like DnsPermission). However if you're using Mono's System.dll under MS runtime the security exception is (most probably) because it tried to call unmanaged code (which isn't permitted by default to non-local assemblies).

My initial answer is no because it would have to be compiled into the calling class; however, I am thinking that system.reflection would be able to help me. Is it possible? Yes. Will System.Reflection do it? It depends. It can't do it alone, though. The easiest thing to do would be to: 1. Define an interface 2. Use System.CodeDom to (a) generate skeleton C# code, (b) include the code from the database into the CodeDom code, and (c) compile the code into an assembly. The CodeDom code should implement the interface defined in (1). 3. Load the assembly at runtime 4. Instantiate the type from the assembly at runtime, through the numerous mechanisms .NET provides (Activator.CreateInstance, etc.) 5. Cast the type created in (4) to the interface defined in (1) 6. Invoke the code via the interface method. A Variation would be to use a delegate instead of the interface. A pitfall with this framework is that all methods defined in the database must conform to a single interface, so you couldn't have methods with different argument lists and return types defined this way. To work around that, you could use System.Reflection.MethodInfo, but this complicates your client code as you need not only need to know what function to call, but also what arguments to provide it, what it returns, etc. This can be done, it's just not as simple or as fast as the above solution. (Regarding performance, CodeDom generation will be slow, but it can't be avoided. Method invocation also can't be avoided, but delegate/interface invocation is *much* faster than MethodInfo.Invoke, so if this code will be invoked frequently, a well-defined delegate/interface would be preferred.) - Jon ___ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list
[Mono-list] UDP Broadcast Socket.ReceiveFrom Anomalies
I'm writing (actually trying to simulate) a simple UDP client and I've noticed some
anomalies between Mono 0.31 and .NET in terms of
the handling the messages. I'm assuming because the replies from the server are
broadcasts.
1) C: 1.1.1.1 - 1.1.1.2 (or 1.1.1.255) S:
2) S: 1.1.1.2 - 1.1.1.255 C:
With mono, the client only gets the data from the server if the message 1 is sent to
the server's broadcast address. The client
ignores the data if it was sent to the server's unicast address. With .NET it receives
the data regardless of the destination address
of message 1. Whether or not the socket option is set to broadcast doesn't make any
difference.
In both cases the server is responding the same (verified with tcpdump) and there
isn't anything weird (like non-Ethernet II frames)
at the datalink layer. There is also a discrepancy between the value returned by
s.Available. Mono returns just the length of the
next message but .NET returns the length of all the responses.
And I've seen http://bugzilla.ximian.com/show_bug.cgi?id=45959
Any ideas? I'm assuming I made a simple mistake, and .NET is more forgiving?

RE: [Mono-list] I broke XSP
It definitely exists. I have directory browsing on and I can actually click the file and it still 404's. -Abe = Original Message From donaldi sp [EMAIL PROTECTED] = Abram Gillespie wrote: Hey All, I seem to have broken XSP somehow. I was having a problem with an ASP.NET page where I was using codebehind as opposed to inline code. It took me a while to get it working, but I finally did. However, when I made changes to the code, the changes didn't propagate (at least as far as I could tell, is this a bug?). So I tried deleting the cached dlls in /tmp. This may have been the step that broke things. Now whenever I try to hit my pages I get: Server error in '/mono' application Cannot find '/mono/whatever_test_page.aspx'. Description: Error processing request. Error Message: HTTP 404. Cannot find '/mono/whatever_test_page.aspx'. (where whatever_test_page is any example page that comes with mono) I've tried rebooting and deleting .wapi (as per another post). No dice. Thanks in advance as always. -Abe ___ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list make sure that file is exist, especially the case sensitive isue ___ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list
