Re: [Mono-dev] [MonoTouch] what happens with MonoTouch and Mono for Android now
...and that on Miguel blog was the suspected good news??mmm, very uncertain the mono future is... I really sad for the mono team situation and the decision of Attachamate, specially after such a great last couple of years of mono related products...just hope that at least the mono core survive and not be forced to re-write all my code in mmm java?...what else do we have?

Re: [Mono-dev] linux Serial Port
Hi:
try to give user permisions to /dev/ttySx or /dev/ttyUSBx depending on
the device that you using...
you can do it more permanently with a udev rule, but try first just
given permision to the user that is going to run the program...
cheers!

I have simple window having a grid of buttons. Actually, I wanted to implement Text to Speech so that on pressing a button, a specific sound comes up. For normal C#, this is done by speech api’s (adding references of T TS Reader) but will this work the same way for my application too? if the TTS lib that you are referencing/using do native calls (p/ invoke) for specific OS API functions (as most of the TTS Windows libs do, as far as I know), they will work just on that OS probably..Linux have some very cool TTS engines, so as part of the monoBOTICS (http://www.monobotics.ic.uach.cl ), we include some simple wrappers for espeack, festival and some other.They are simple in terms that they mostly interact with the command line TTS engine program, so, no much use of the engine api directly for customization at the moment, but they do what is needed. The lib can be use it as stand alone is gpl and the linux tts engines also work on Windows, or a small and easy wrapper for some of the Windows libs is also possible for a cross platform solution Cheers, Mauricio -- View this message in context: http://mono.1490590.n4.nabble.com/Text-to-Speech-using-Mono-tp2544906p2544906.html Sent from the Mono - WinForms mailing list archive at Nabble.com. ___ Mono-winforms-list maillist - Mono-winforms-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-winforms-list ___ Mono-winforms-list maillist - Mono-winforms-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-winforms-list

One another thing to add weirdness to all this, is that this was working Ok on Fedora 10 to a certain point, then in some moment, the ffmpeg guys (or RPM packagers), beging to provide libdc1394 as a separated package/lib (previously was included in ffmpeg-libs package), and from that moment the problem show up. Currently if I remove libdc1394xxxzzyy.RPM from my sys and both code are more happy together (not entirely becouse ffmpeg beging to act weird since it miss those bits, the libdc1394 need to be removen by force --nodeps to avoid uninstall the hole ffmpeg packages and some other softwares).

Re: [Mono-winforms-list] Casting question (creating things on the fly)
Hi Paul: What you can do is deserialize a object from a previously XML serialized object, something like: http://www.devhood.com/tutorials/tutorial_details.aspx?tutorial_id=236 When you serialize a object to a XML file, you are saving the string representation of the object state at a given time, fron there you can rebuild the object when you want from the stored info on the XML.. To find more usefull info about it, use C# XML Serialization on Mr. Google :-) Hope that it helps and if is like the thing that you are looking for Cheers!

Re: [Mono-dev] Syscall.mmap problem
ok, sorry but I don't recive the previous mail I check my trash and spam
forlder but nothing...
anyway, here is the situation:
in my mmap test the /pr.txt file exist so the error handling is only
for test porpuses and to watch if any of the mmap paremeter is wronge
(this is a test of the mmap not the final working with the mmap on the
video4linus.net), in my case the file descriptor is correct (not 0),
in any case thak you Jonathan for your test code, if I run your code I
get the same Console.WriteLine(start.ToString()) = -1 and this message
with the error handling:
mmap: Value too large for defined data type //I don't know what means
the lenght returned by len = statbuf.st_size is 6 and this is correct
becouse is the same value as the C code and offcourse is the lenght of
the file.
In other mail Jonathan ask me about the len and offset values, the len
is 6 and offset 0, is the same code of a C working mmap program.
I don't know what else can I check...
thank you.

throw new Exception(mmap crash.);
do you see some mistake?, I use Fedora 5 with mono-1.2.5.1, may be you
can send me a workin Mono.Posix or Mono.Unix dll, becouse I prefer don't
compile all mono stuff only for this dll, becouse all other stuff work
perfectly.
In advance, thank you very much.

[Mono-dev] C# festival TTS wrapper
Hi: Recently I build a very, very basic Festival (text to speech engine) wrapper for C#, with this you can make talk your C# app :-), anyone interesting?, where can I put the files to make this available?. bye.

Re: [Mono-dev] [Mono-devel-list] Operating System in C# Project
sorry, what is the main idea??, develop a operating system in C#, sorry I lost the first post. If that is the case, I have a prototype OS in C# (for educational pospuses only), offcourse is very, very, very basic, for the moment only open one or more proto-assembler files (like compiled programs), and allocate memory for each proceess, define a PCB for each process and begin the execution of each assembly line with a implementation of the Round-Robbin algorith, also do context change to change from one process to other ready process, and show all the execution information. anyone interesting??

What interests me most about this is a C# program as a first-class citizen, or really, every API in the system being not only available, but *designed for* managed programs. I think a good example of that can be found in Microsoft's DirectX, which we were just discussing. Compare Managed DirectX to XNA. The differences are big. XNA exposes, for the most part, the very same APIs, but in a much more intuitive and friendly manner than Managed DirectX. You could consider fully object-oriented operating systems, where the design of the API is every bit as important as its concept. You could organize the system around safe plug-ins, each providing some service to the whole, such as a windowing system, file systems, etc., but which are most importantly *as easy to write as implementing an interface or an abstract base class.* I'd be very interested in participating on design of such a thing. I've been trying to teach myself good object-oriented design over the years, and I think I would have some good input to give past the initial problem of booting such an environment. Perhaps the project could be approached in two stages? Half where we boot the managed environment, and half where we assume the managed environment. You could design and implement these independently of each other. You could even design a set of classes to emulate the kernel on top of an ordinary runtime, for the purposes of unit testing. One strategy I've become fond of, especially where components and unit testing come into play, is generous use of the IServiceProvider interface; if components accessed kernel objects this way (or a similar way, where you ask for a base class but not a specific implementation), they would neither need to know or care whether they're using the real thing or not.

[Mono-devel-list] some GtkGlExt-Sharp list??
Hi to all: Anyone knows about some GtkGlExt mail-list??, I try to work with TAO/OpenGl in a Gtk window on mono/linux, and I need some help, I can make a glut window from a C# program on mono/linux with TAO, but I don't know how to make some opengl stuff inside a gtk window. Any idea??, any list about this kind of stuff?? Thanks Mauricio ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
