The point is that I'm developing a program in which the GUI is generated dinamically (i.e. widgets come and go with the user interaction) so one of my business classes contains an array of Gtk.Widgets (the ones which are added to the interface). So, somehow, I need to keep this info for the next restarting of the program (in order to keep the interface as the user wanted before stopping the program). At this point the choices were: 1) Back-up the object at a OODB 2) Back-up the data at tables in a RDB 3) Make a config file where I put the needed info to reconstruct the objects (with the widgets) at starting time 4) Serialize the objects before stopping the program and deserialize them at starting. And, well, you know my choice. Any suggestions and/or advices will be welcomed.

RE: [mono-devel-list] System.Drawing.Pens test patch
Hi Ben. Thanks for your comments. What you suggest is really the cleanest solution. Unfortunately, to use it, it's necessary to separate positive parts of tests from those that are expected to throw exceptions. In part of places, it's relatively easy to do, in other it requires refactoring of the whole class (see TestSystemPens.CheckMethods() for example). So it's not worth the effort to do big changes in the tests right now. If you guys consider my patch as improvement of current situation, I'll commit it. Thank you.

[Mono-devel-list] mcs patch for default encoding
Hello,
I've attached a fix for mcs to not use Latin1 encoding everywhere.
I think it should be default encoding of current culture (for
example the codepage is 932 on my Japanese environment, neither
28591 nor 1252).
But in case we really don't have the corresponding encoding that
CultureInfo.CurrentCulture.TextInfo indicates (it should be
supplied though), we should use culture-independent encoding, so
I think it should be utf-8, instead of iso-8859-1.

The _easiest_ way to get 100% functionality (from a Fx point of view) out of a native library (which is the only safe way it can replace the managed implementations) would be to re-use the SymmetricTransform class (internal in corlib, public in Mono.Security.dll). That way you'll get all the required cipher and padding modes (and that includes the feedback issue you have) without any pain. The only thing to implement would be the basic ECB mode for each native algorithm. This approach won't result in optimal performances, (mostly) not because of the SymmetricTransform (managed) code but due to the many calls from managed-to-unmanaged code (one for each block). But this is something that could be fixed/enhanced later. Anyway even if you want to get everything from OpenSSL, using the SymmetricTransform class would still be a good development step to test your wrapper code.

[Mono-devel-list] Development of OpenSSL Wrapper for use with MONO [as well as MS.Net]
I've begin developing a wrapper around OpenSSL and have successfully wrapped the Hashing functionality with little trouble. My next stage is wrapping the Symmetric encryption functionality. Unlike the other EVP based encryption methods in OpenSSL, it does not offer a function to dynamically allocate the state structure. I'd rather avoid having to develop a wrapper dll just to allocate a structure. Any suggestion as to how to allocate the EVP_CIPHER_CTX structure? It has pointers in it, so if I were to allocate it within Mono with Marshal.AllocHGlobal I'd have to at least set it to check the size of pointers. Has anyone worked with OpenSSL for a while? It'd be good to know if that structure has changed or is likely to change. My final step is to setup the RSA, DH, and DSA encryption. (DH isn't necessary to complete the System.Security.Cryptography namespace for Mono). With .Net 1.x it seems that DSA is an un-inheritable class due to its internal constructor. How should I work around this issue? My current idea is to create a class to inherit from DSA that will be included in the Mono compilation process that will take advantage of the publicly usable wrapper class.

This patch should fix the issue. It doesn't really implement the thing
correctly (it should really have the pause instruction to help
hyperthreaded processors), but it's better than throwing.

They have absolutely nothing to do with each other. SpinWait is designed
for spin locking (not really something you would ever do in managed code
-- the standard Monitors can take care of doing spin locks as are best
for the user's machine).

RE: [Mono-devel-list] Thread SpinWait not supported? Interrupt ?
I think that this answers it: Search of archives shows 2002/2003 mail-list items saying its a TODO, and not high priority And it's probably still not a high priority. SpinWait is a more efficient wait then the standard blocking mechanism (in most cases), but since it is only a more efficient version of Wait it is not implemented yet. SpinWait goes into a loop to grab the lock before giving up and entering the wait state...and no, it is actually more efficient because if you can grab the lock before entering the wait state, the better the performance.

The cleanest way to do these is to factor each out into a different
method and use the ExpectedException attribute. First, this is much
cleaner. Second, both the old code and your suggestion don't do as much
checking as possible. ArgumentException is a base class for other
exceptions.
[EMAIL PROTECTED]:~$ monop ArgumentOutOfRangeException
[Serializable]
public class ArgumentOutOfRangeException : ArgumentException,
System.Runtime.Serialization.ISerializable {
With ExpectedException, nunit tests the exception thrown is of the
*exact* type specified in the attribute. However the "is blah" tests and
the catch (Blah) clauses catch any derived types. So, they are not as
good of tests.

Hi, I'm writing a front end to my monoupdater script and have a simple question. Is there an order as to where things should be compiled along the chain? For example, it looks like it should be mono/mcs -> libgdiplus -> gtk-sharp -> gtkmozembed -> gtksourceview -> monodoc -> monodevelop (mono compiled first and so on). This holds fine for the above, but are there any others which need to follow the above sort of route?
