Re: [Mono-winforms-list] How to use Metafile.
If your project can be AGPL licensed or you can pay their commercial license, the best thing to generate high qualitty printable results is iText# Home: http://itextpdf.com/ Download: http://sourceforge.net/projects/itextsharp/files/. You generate a PDF with iText and then you can either print directly in Linux, or call any pdf-printing software in Windows/Mac (Adobe or else). Another possibility is the SVG format. (Se http://www.codeproject.com/KB/cs/svgnet.aspx, for example). I migrated the svgnet code to github repo: https://github.com/monoman/SvgNet Metafiles is windows specific, proprietary and very badly documented, so avoid them for anything that means to be portable. Hope it helps, Rafael Monoman Teixeira --- We live in a world operated by science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces. -Carl Sagan On Tue, Nov 16, 2010 at 8:39 AM, Anubhava Dimri anubhava.prod...@gmail.com wrote: Hello Everybody, I am using Metafile with vb.net i have generate the problem with Metafile to MONO.

[Mono-aspnet-list] Can't install XSP as daemon on Debian
Hi, everybody. I ran into next problem: After building and installing of new version of XSP (from git master, 14 nov and 14 sept accordingly) it doesn't run as a daemon and brings the system into non-operable condition (it can't boot). It looks like this: other daemons start xsp Listening on address: 0.0.0.0 Root directory: /home/godfather/Projects/Test Listening on port: 80 (non-secure) And that's all. The system is stucked and only recovery mode helps. I'm installing it next way: $ sudo cp /etc/init.d/skeleton /etc/init.d/xsp PATH=/sbin:/usr/sbin:/bin:/usr/bin DESC=Mono XSP4 NAME=xsp4 DAEMON=/usr/bin/$NAME DAEMON_ARGS=--port 80 --nonstop --root /home/godfather/Projects/Test PIDFILE=/var/run/$NAME.pid SCRIPTNAME=/etc/init.d/$NAME $ sudo update-rc.d xsp defaults Is it XSP bug?

Re: [Mono-dev] C# source-to-source compiler
Hello, I just noticed this thread, and I'm curious, when you say: The async/await is about asynchrony and spawn/sync is about parallelism. These are 2 different things which should not be mixed together. Do you mean they should not be confused, or do you literally mean that these technologies (or paradigms, if you will) should not be combined? If this is the case, I'm curious to learn why you say that, since I'm toying with idea of hybrid threading for a concurrency framework I'm working on (https://github.com/nirvanai/Cirrus). I don't see any problem combining these two together when needed, my point was simply that they mean 2 different things. Mono C# compiler has no async support yet (the .NET preview has been announced few days ago!) but we are fully aware of it and we will implement it as soon as time permits. I implemented async methods (before I knew they were to be a language feature) using Cecil for the framework I mentioned. I think the coroutine transformation I'm doing is pretty similar to the way Microsoft is doing things in their async preview. I'd certainly be willing to take a stab at adding async support to the Mono C# compiler if/when you think that might be beneficial. Patches are always welcomed. However, the approach will be different as the rewrite will happen at expression level (you don't need Cecil).

[Mono-dev] Porting db4o-tool to use Mono.Options rather than Mono.GetOption
Hi, I'm working out some bugs in db4o so that the upcoming version 8.0 will build out of the box on mono. Currently, it ships with its own version of Cecil, CecilFlowAnalysis and GetOptions. While I can live with the Cecil bits and pieces, GetOptions is dead in the water with mono-2.8 and (from what I can see) has been fazed out since mono-2.2 so rather than continue to support it, I'm trying to port it over to use Mono.Options. Okay, the pre-packaged Cecil stuff will cause me problems with building for Fedora, but that's another story. My only problem is that I can't see an equivalent of return WhatToDoNext.GoAhead; in Mono.Options. Is there such a beastie and if there is, what is it called?

I am converting our current Windows WCF web service to mono. When I try to instantiate our ServiceHost object... ServiceHost selfHost = new ServiceHost(typeof([WebServiceClass]); I get a not implemented error. I figured this is due to something in the existing web service that is not implemented (reasonable). Because I can not find anything in there, I created a new class with no methods, and tried to use it in place of our web service... same error.

I know you can call a base class constructor using : base after the

i=_i;
}
}
public class B : A
{
public B (int a, int b) : base (a+b) // Calls A constructor with _i
as _a+_b
{
}
}
But what happens if you should made some more complicated that cannot be
done in that way???
For example:
public class C : B
{
public C ()
{
MyDataStruct data = GetDataFromTheDatabase ();
base ( data.a, data.b ); // This will not work, indeed, but
illustrates the idea...
}

All the GTK built-in behaviors are implemented as event handlers, but GTK offers a way to stop events from propagating to other handlers (set RetVal to true), so built-in handlers often swallow events. You can use ConnectBeforeAttribute to insert handlers before the built-ins. Note also that you should use the Drawable object from the expose event's Window property, not the widget's GdkWindow property.

as _a+_b
{
}
}
But what happens if you should made some more complicated that cannot be
done in that way???
For example:
public class C : B
{
public C ()
{
MyDataStruct data = GetDataFromTheDatabase ();
base ( data.a, data.b ); // This will not work, indeed, but
illustrates the idea...
}
}
This is a question more focused on C# than in mono itself, but I hope
not to disturb no one doing it here since the list has not very high trafic.

Re: [Mono-list] Calling a constructor from within another's code
I don't think so.
It's the same in Java, the super() call must be the first instruction.

You could always move the base constructor code to a protected method and

[Mono-list] How can I copy one drawable into another?
Hello, I've a Gtk.Image widget with a given content and I just want to copy that content within a Gtk.DrawingArea, is this possible in an easy manner? Thanks in advance, ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list
Re: [Mono-list] Calling a constructor from within another's code
Hi,
I should have explained my earlier example a bit better, Here Goes;
public class C : B
{
public C() : this( new GetDataFromTheDatabase() ) {}
private C( GetDataFromTheDatabase data ) : base( data.a, data.b ){}
}
This takes advantage of the fact that you can chain into other
constructors in your class.

Re: [Mono-list] How can I copy one drawable into another?
Hi Francisco,
If you have a png on disk, this is done like so:
void PaintImage( Context ctx, ImageSurface img, int x, int y ){
img.Show( ctx, x, y );
}
...
ImageSurface image = new ImageSurface( filename );
PaintImage( ctx, image, 10, 20 );
If you have a Gtk.Image and want to turn it into a Cairo ImageSurface
then you at the moment have to do something horrible like this:
Gtk.Image myImage;
...
Gdk.PixBuf buf = myImage.PixBuf;
buf.Save( temp_convert,png );
ImageSurface image = new ImageSurface ( temp_convert );

Once you have it in a PixBuf, just paint it onto your ImageSurface:
using (Cairo.Context g = new Cairo.Context (mySurface)) {
g.DrawPixbuf (mypixbuf, new Cairo.Point (0, 0));
}

Re: [Mono-list] Text on Cairo
Hi Francisco,
As far as I know, text extends are to work out where the boundaries of
your text will be after you write it, this is useful if you want to put
several strings next to each other ( eg, write the next word or next
line ). You would use the extends to find out how many cairo pixels tall
the string would be.
If you just want to print one string of text starting at a particular
location on screen and don't need to know how wide or tall it ends up
then you can safely do this:-
public void StringAt( Context ctx, string str, int x, int y )
{
ctx.NewPath();
ctx.Color = new Color( 0, 0, 0, 1 );
ctx.SetFontSize(12);
ctx.MoveTo(x,y);
ctx.ShowText(str);
}
If you wanted to use extents to find the boundaries of your text you
might do this:
public void StringsInRows( Context ctx, string[] strlist, int x, int y )
{
var next_y = y;
// print strings in lines
foreach ( var str in strlist ){
ctx.NewPath();
ctx.Color = new Color( 0, 0, 0, 1 );
ctx.SetFontSize(12);
ctx.MoveTo(x,next_y);
var extent = ctx.TextExtents(str);
next_y += (extent.Height + 5); // next line will be 5px under this
line
ctx.ShowText(str);
}
}
Hope that helps
Regards

Hello there,
I'm currently fighting with Cairo's text system, and I should to admit
that I've a slight headache...
The main problem that I've is that, for coherence, I would like to
specify a point (as a pair of x,y coords) and the text should be drawn
taken that point like the top-left point of the text.
I think I must use TextExtents and/or FontExtents for this purpouse, but
I didn't figure out HOW.
There's an explanation in this tutorial:
http://www.mono-project.com/Mono.Cairo_Tutorial#Understanding_Text
But unfortunatly the code is missing.
Does someone has some code on this issue that he/she dont mind to share???

Re: [Mono-list] NotImplemented error creating WCF ServiceHost
Exactly, the exception is thrown from WCF itself. And that exception tells you that you cannot use the feature unless someone implements it. Though it would be almost impossible to find out which configuration part causes the exception unless you are very familiar with configuration settings or you give up using configuration. It is also likely you are using unsupported feature anyways. Atsushi Eno (2010/11/17 2:23), BrianDonegan wrote: I am converting our current Windows WCF web service to mono. When I try to instantiate our ServiceHost object... ServiceHost selfHost = new ServiceHost(typeof([WebServiceClass]); I get a not implemented error. I figured this is due to something in the existing web service that is not implemented (reasonable). Because I can not find anything in there, I created a new class with no methods, and tried to use it in place of our web service... same error.

Gdk.CairoHelper.SetSourcePixbuf (g, pixbuf, dest.X, dest.Y);
