Shouldn't it be:

buf.Append(s);
Passing some random junk (ergh.. does new byte[] clear memory?) to
encodoer doesn't seem good idea.

[Mono-list] monodoc missing docs + Monodevelop question
Hi, I have mono, mcs, gtk-sharp and monodoc from CVS, all compile fine, and can be used. I still have two small problems: * monodoc: everything compiles fine, and monodoc works but the documentation for some assemblies is now missing, like the Gnome subtree in the docs. Normally, just compiling and installing was sufficient to get the complete reference. * Compiling MonoDevelop I get: ./Dock/Docker.cs(14) error CS0246: Cannot find type `GtkSharp.ExposeEventArgs' ./Tree/TreeView.cs(67) error CS0246: Cannot find type `GtkSharp.EditedArgs' ./Tree/TreeView.cs(249) error CS0246: Cannot find type `GtkSharp.TestExpandRowArgs' While I think GtkSharp.ExposedEventArgs, EditedArgs and TestExpandRowArgs code is included and public accessible from within gtk-sharp.dll.

Well the docs on GetString say it can be just a byte[].
The interesting thing is the length which only works as 1448 which is a
number I found by printing out the len variable. If I set the byte[] to
say 1, sock.read (which should really be named stream.read as it's a
NetworkStream) always returns anywhere from 0 to 1448 bytes but never
more.
I also tried the example from the .NET docs and it doesn't work either.
It reads up to 1448 bytes and the stops. The code is here:

Yes, GetString(byte[]) exists, but it's equivalent to this:
string GetString (byte[] bytes)
{
return GetString (bytes, 0, bytes.Length);
}
So this is only valid if `bytes' is full. Otherwise (when you've read
fewer than `bytes.Length' bytes) the end of your string will contain
garbage data. The `GetString (bytes, 0, len)' fixes this, so GetString
will only convert valid data.

Right, I did go and read up on GetString and you are of course correct.

Re: [Mono-list] Gdk: Text drawing on pixmap
Hello, I have an application that draws rectangles, lines, etc on a pixmap. The Gdk.Pixmap class is ideally suited for that purpose, as it has methods for drawing lines, rectangles, images on the pixmap. Now I also need to draw text on the image. Pixmap however does not have a method for drawing text, so is there possibly another way I can get text on the pixmap? Look at the mlist source code (on the Gtk# wiki), it shows how to do this. Or the list.cs widget in monodoc, that is another example. ___ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list
RE: [Mono-list] Docs as plain HTML
Do you or anyone have a monodoc.dll for windows? I could try to create a SWF app. I say try because I've written more GTK# apps than SWF. Monodoc really does not have any strange dependencies, so it should work just fine on Gtk#/Windows. ___ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list
Re: [Mono-list] To draw or not to draw that is the question :)
Hello, I've explored GTK and I saw that drawing in Gtk.DrawingArea involves using Gdk.Drawable which in turn requires learning some of Pango (?)... I guess Pango implements what I think it is the functionality of System.Drawing, no? Gdk implements the drawing primitives, it is fairly low-level. Pango is a text-setting facility that you can use to render. Now, I'am confused what library I should use to draw... Should I use System.Windows.Forms (with Mono-wine or something?) or should I use GTK and use that Pango thing? Gdk for now. I have a patch that lets you use Cairo (it was posted to the gtk-sharp-list) to draw, which is simpler to use than Gdk. In the future we will integrate System.Drawing and/or Cairo into Gtk# so it will be a familiar API. I dont know what is being made in this direction so I dont know what to do Another question is what should I use to do image manipulation (resize, chopping, do thumbnails, etc) in a server (in ASP.NET for example) without installing the whole X package ? Work is underway to have a complete System.Drawing implementation. CVS should let you do this. Miguel. ___ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list

This is fixed in cvs.

Hello everybody,
I've found a bug, but I'm not sure about how to report it (I mean I
can't
find a suitable subject and other info):
The following source code compiles but its execution results in
incorrect
behavior:
code
using System;
namespace Test {
public class A {
public static void Main () {
A a = new A ();
a.Test ();
}
public void Test ()
{
A a = new A ();
// the following is the problematic line
_intValue += a.Value + a.Value / 2;
Console.WriteLine (_intValue);
}
private int _intValue;
public readonly int Value = 100;
}
}
/code
The actual result is 50 but I think it should be 150.
I need someone to give me instructions about the affected product
(Mono/Compilers or Mono/Runtime or ...) and a suitable subject if
possible,
or to tell me that this is not a bug and I'm plain wrong :-)
If someone can file the bug report for me it's ok too.
TIA,
Rodolfo
