Hi Peter, As you may have noticed by now, shutdown is not yet clean. Goes along the lines of the bug you filed about memory stuff on shutdown. Since it's shutdown and the app is done it's not highest on our priority list. It's mostly related to order of window destruction and explicit vs. implicit window destruction. Wasn't sure, so I thought I'd mention it here first. Thanks for the heads up.

[Mono-devel-list] Graphics merge-in status
Hello.
Yesterday I finished merging out our changes to System.Drawing. Vast
majority of changes were java-specific.
The next thing I want to do is to commit the drawing tests helper we
started to develop at Mainsoft.
I will create a directory under sys.drawing/test for this helper and
will commit the helper as is. It needs few changes, however, to be
usable for Mono. Today it checks TARGET_JVM to decide whether we are
creating reference results on dotnet, or run tests. Of course, it does
not suite Mono. I'd like to hear your ideas on how better to fix that.
Few words on the idea of this tool.
It is supposed to aid in writing tests that result in drawing. So there
is a class that provides 3 main features:
* Graphics property which can be used for any drawing operations
* Show method that opens a window with the result of the drawing to see
results manually
* Compare methods family - I will explain that in more details below.
So a typical test case will look like:
[Test]
public void DrawRectTest ()
{
DrawingTest t = DrawingTest.Create (200, 200); //create helper
class instance with drawing area of this size
t.Graphics.DrawRectangle (Pens.Blue, 10, 10, 150, 180);
t.Show (); // optional
Assert.IsTrue (t.Compare ());
t.Graphics.DrawRectangle (Pens.Red, 50, 20, 190, 30);
Assert.IsTrue (t.Compare ());
}
Now I will explain what Compare is all about.
When it's run on dotnet, Compare always returns true and as a side
effect it creates expected result named DrawRectTest:X where X is the
sequential number of the call inside DrawRectTest function. The name of
the function is extracted from the call stack.
When it later is run on java, Compare will find the expected result that
dotnet created and compare the FFT of the resulting bitmaps. If the
bitmaps were similar enough, it will return true. There is an overload
with tolerance parameter, for fine-tuning weird tests.
The comparing itself is done very approximately at this stage, actually
it's very easy to confuse the algorithm. It only calculates the sum of
the squares of all FFT values for every picture and compares the sums
for java and dotnet. This was done because it's very easy to keep one
number per expected result.
Any questions and suggestions are welcome.
Andrew.

This precludes us from using the assembly in mscorlib.dll. It could
potentially be useful to use there -- say to let us write nunit tests
that poked at internals.
I'm not very sure about the scenarios you are thinking in. Could you
please show some detailed examples?
See http://blogs.msdn.com/junfeng/archive/2004/09/14/229254.aspx about
how there is support for handling commas in file names. Your code would
break under this.
Well, I didn't know about that, but IHMO I find it like a very bad
practice, and I'm sure that there aren't people out there who like to
call their assemblies 'My,Assembly,Version=xx... or something like
that.
Also, to test this, I tried to load an assembly named
'Test,Assembly' (using Assembly.Load ()) in both mono and ..NET, and
neither could load it successfully. The only way to work with it AFAIK
is when you get name of the assembly itself, or use Assembly.LoadFrom.
So, I don't think it's that important. But, if anybody find it
neccessary, we could add it.
Finally, comparisons should be done with the invariant culture.

Thanks, I just noted that's the way the comparisons are done in the

+while (GC_world_is_stopped GC_stop_count == my_stop_count) {
Imagine that this thread gets a spurious signal. The
GC_stop_count++ statement has already taken effect, but the
GC_world_is_stopped = TRUE has not, the thread would bypass
the wait, causing the world not to be stopped.
In fact, how do we know that my_stop_count is correct?
When I put this in the mono tree, I'd really have something
with barriers in it and use the version that I suggested.
Without the barriers, am a bit worried about the correctness
(especially since the issues happen on platforms I am not
testing with).

Re: [Mono-devel-list] C or C# and Card Reader
For security concerns (virus/trojans/etc.) normally web content isn't allowed to interoperate with local programs. You must have things sandboxed to prevent harm to your client system by malicious web content. You can approach a need like your from many angles: -- Create browser component (a Firefox XPCOM/IE ActiveX component), with a VERY thoughtfully SECURE design (for example requiring ssl connection (certificate-signed) to just an specific URL to enable gathering information from the serial) to embed in your page. This means digitally signing packaging the component to be able to have it trusted by the browser/system. The page javascript would possibly post the information gathered by the component to navigate to the new page. Commentary: A java applet would not be able to talk to the serial port inside the browser sandboxed VM, so it isn't a choice here. -- Invert command: Embed the HTML viewer in the client application that conducts all the operation securely just using the viewer to show the results. -- Skip web content altogether: Write a good (GTK#) GUI application for the whole issue, talking web services with the server. Clearly mono can be used easily for the last two suggestions, but currently isn't able to help implement the first one.

I've never understood is why Novell doesn't (and Ximian didn't) make working SRPMs or SPECS available that correspond with the RPMS they distribute.

This effectively means that to support EnC, I must write my own compiler. I would never try to that, but fortunately there is mono to save the day. I would like to use the mono compiler to produce the necessary deltas, which I must feed to MS runtime. The problem is the I know neither the internals of mono compiler nor the internals of System.Reflection.Emit and implementing support of EnC would be a tedious or impossible task for me. There is no documentation about what the MS runtime expects in the edit and continue metadata tables. You could get someone living in a free country to reverse engineer the metadata tables and write a spec. Then we could start to see if the spec is easily implementable in mono's reflection.emit code. My guess is that it would be quite complex to implement _and_ make it work with the MS runtime.

[Mono-devel-list] Initial ARM JIT port in svn
Hi. People may be interested to know that the initial pass at the JIT port to ARM is in svn. make test in mono/tests reports 123 pass, 70 fail. Most of the regression tests in mini/ work as well. The missing stuff is related to stack walks (so exceptions don't work yet, as well as some reflection features) and some specialized opcodes.

At this time I'm interested about compilation issues on different systems (like with older processor versions, v4 and newer). Also, if anyone has a big endian ARM system I would be interested in bug reports. Soft-float support is planned only for later (and you may speedup the process by doing the support yourself or providing me a tarball of a complete system compiled with soft-float).

Re: [Mono-devel-list] Error Building
You need mcs to build mcs since it's written in c# :-) That's why you need a tarball or similar to get a working mcs.exe. ./configure checks the capabilities of the particular unix version you are running on, to figure out the proper compiler switches, include files, features, etc, that your system supports. the configure script is generated when you run autogen.sh. You could try 'make get-monolite-latest' to get a working mcs to bootstrap your build (see the mono README) Cheers, Peter -Original Message- From: Jonathan S.

Nothing is ever subscribing to your event, so it is null when you are
trying to invoke it. You need something like:
OnInputError += new InputError (ErrorHandlerFunction); somewhere.
A few general style comments:
1. Normally event handler delegates are named somethingHandler. So
your InputError delegate would be named InputErrorHandler.
2. Normally events names don't start with On. So OnInputError would be
InputError.
3. It's common to wrap the instantiation of an event in a protected
method named OnEvent Name. So you would have a method that looks like
this:
protected void OnInputError (InputErrorEventArgs e)
{
if (InputError != null)
InputError (this, e);
}

What happens of the results are NULL?
You should check for NULL first.
Then, are you sure that operatingsystem and nodeid are varchars or some other
type that translate into string?
If not then you would get that exception.

Re: [Mono-list] Npgsql error
Cool, a question on that:
What happens if a exception occurs?
I meand close() gets called at the end of the using block, but does it get also
called when an exception occurs (sort of finally)?
If yes, I'm changing my programming style :)
Another question, how would it look like if you had to catch an exception (i.e.
to rollback a transaction)?
Thanx :)

Hi Emil,
Also another tip: you don't need to explicitly set connection etc. to
null.
Cosider following improvement:
IDbConnection dbcon;
IDbCommand dbcmd;
IDataReader reader;
try {
...
} finally {
// cleanup, even if error occurs, closing the reader is important
because while it is open no other reader can be opened
if (reader!=null) reader.Close();
if (dbcmd!=null) dbcmd.Close();
if (dbcon!=null) dbcon.Close();
}
A small tip: Your example is very java-ish. You could reduce the amount
of code by using C# using() statement which provides automatic cleanup
for connection, command and reader. I believe that the following is much
more readable and saves a lot of typing:
=
using (IDbConnection c = new NpgsqlConnection(connectionString))
{
c.Open();
using (IDbCommand cmd = c.CreateCommand())
{
cmd.CommandText = ...;
using (IDataReader reader = cmd.ExecuteReader();
{
while (reader.Read())
{
}
}
}

I realised what I was doing wrong. I didn't have the test for null if
(InputError != null) in my original code, and as I wasn't at the time
subscribing to the event, it was naturally going to error out.
By the way the code I sent in is pretty much what you'll find on page
309 (Chapter 6 Advanced C# Topics) of Wrox's Professional C#. That's

Can anyone see anything wrong with this code. It looks to me to be
correct syntax for defining and raising an event. It compiles without
error, but when I run it I get the following error message
Nothing is ever subscribing to your event, so it is null when you are
trying to invoke it. You need something like:
OnInputError += new InputError (ErrorHandlerFunction); somewhere.
A few general style comments:
1. Normally event handler delegates are named somethingHandler. So
your InputError delegate would be named InputErrorHandler.
2. Normally events names don't start with On. So OnInputError would be
InputError.
3. It's common to wrap the instantiation of an event in a protected
method named OnEvent Name. So you would have a method that looks like
this:
protected void OnInputError (InputErrorEventArgs e)
{
if (InputError != null)
InputError (this, e);
}

[Mono-list] Gnome and Kde and how the mono project works with them .......
I have just recently run in to a gtk-sharp issue on a kde desktop. Went to gnome on the same machine, and all is fine. It just got me thinking .. I don't really have a preference to either desk top, i just have been running KDE for years and years because it probably came up stock on an old distro. I see obviously direct support for gnome in the mono project, and of course gtk# appears to be where its at right now for gui with mono apps. That having been said .. I am about to roll out some mono/gtk# apps to a pool of about 1000 people working for various fortune 500 companies in US and fortune 50 companies in Canada. and I pick the desktop they run, and until now that is KDE. Since I am doing everything now in mono/gtk# on Linux (for these clients), (now) and in time want to have the most optimum desktop environment for these people, is it correct to say I should obviously be switching to Gnome based on the Mono project direction? If anyone were to guess..what percentage of mono lead developers/maintainers use gnome vs. kde? As far as I gather, mono/gtk# app. will work fine on both desktops but with gnome there will be synergy amongst apps (i.e. drag on to) that KDE will not have? And if this is the case, anyone thought about that type of support for KDE? Is there perhaps maybe a bit of hidden politics at work here too? but I find it odd ... Novell bought SUSE, Novell funds mono (to some extent), suse distro's default to KDE do they not? (pretty sure 9.0/9.1/9.2 do)? Since we see Novell funding mono, owning SUSE, and talk of how tight Gnome and mono may become what is the outlook/piture of KDE in the future. Looks like I am switching to Gnome unless my hunch (post) is completely off base. -tl ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list
Re: [Mono-list] Gnome and Kde and how the mono project works with them .......
Gee, tl, are you sure you want your clients to go through all that re-training and dealing with the (temporary) productivity loss while everyone gets acclimated to the new desktop? Not to mention all the documentation issues, lots of new configuration file changes, etc., that you'll need to deal with. Why not just stick with KDE? If you are concerned about being able to integrate your mono applications smoothly with qt-based interfaces, I would be glad to offer my services as a technical specialist and programmer to ensure your users won't have to deal with functionality gaps and kludgy interfaces to stay with your current environment :-) [sorry if this is a little off-topic] Harry Holt On 8/4/05, ted leslie [EMAIL PROTECTED] wrote: I have just recently run in to a gtk-sharp issue on a kde desktop.

It would be useful to know what the issue is. The goal is to allow desktop-agnostic applications, by using freedesktop.org standards when possible. (This isn't always possible, such as with theme changes and file print dialogs, but the apps should work properly, even if they don't form a coherent whole...) Since I am doing everything now in mono/gtk# on Linux (for these clients), (now) and in time want to have the most optimum desktop environment for these people, is it correct to say I should obviously be switching to Gnome based on the Mono project direction? As Harry Holt mentioned, you should choose whichever environment is best suited for your users. Re-training them may not be cost effective. Plus, it's always possible that someone will write a Qt# binding layer to allow better KDE interop. If anyone were to guess..what percentage of mono lead developers/maintainers use gnome vs. kde? 100% Gnome, AFAIK (though it would help to define lead developers). However, it should be noted that most of mono doesn't depend on Gnome or KDE -- XML, File I/O, everything that isn't GUI-related is completely desktop agnostic, so it doesn't matter that lupus (JIT guy extraordinaire) is running Gnome or FLTK or FluxBox, as the JIT doesn't change on any of those. With that being said, all Mono-related Novell-funded resources are going into Gtk# and System.Windows.Forms, not Qt#. (Which isn't to say that KDE isn't getting any resources from Novell, just no resources that are Mono-related, from what I've seen.) As far as I gather, mono/gtk# app. will work fine on both desktops but with gnome there will be synergy amongst apps (i.e. drag on to) that KDE will not have? And if this is the case, anyone thought about that type of support for KDE? Drag-and-drop should work. Copy/paste should work. If they don't work, then someone isn't adhering to the relevant freedesktop.org standards. What will differ? Themes, dialog boxes, HIG conventions (Mac-style [Cancel][Save] button layout vs. Windows [OK][Cancel] button layout), and more. Will those differences matter? It depends on the training your users receive. For example, Microsoft Office tends to have different widgets and conventions than every other Windows app, yet it does very well. :-) Training can make up for a lot. Don't underestimate its importance. Don't underestimate the harm of Change for Changes sake, either. Many users don't like change. Is there perhaps maybe a bit of hidden politics at work here too? but I find it odd ... Novell bought SUSE, Novell funds mono (to some extent), suse distro's default to KDE do they not? (pretty sure 9.0/9.1/9.2 do)? The missing piece is that Novell bought Ximian, which originally developed Mono and is a big Gnome developer. From the outside, Novell seems to be supporting both Gnome and KDE, but as far as Mono is concerned Gnome is getting all the support. Since we see Novell funding mono, owning SUSE, and talk of how tight Gnome and mono may become what is the outlook/piture of KDE in the future. You'd have to ask the KDE developers that, and I'm sure they feel the future of KDE is bright. Whether they see Mono in their future is another matter, and whether Mono is part of Gnome's future will cause flame wars for years to come. :-) - Jon ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list
Re: [Mono-list] Npgsql error
Cool, a question on that:
What happens if a exception occurs?
I meand close() gets called at the end of the using block, but does it get
also called when an exception occurs (sort of finally)?
If yes, I'm changing my programming style :)
Another question, how would it look like if you had to catch an exception
(i.e. to rollback a transaction)?
The following code:
using (A a = new A())
{
code
};
Is equivalent to:
===
A a = null;
try
{
a = new A();
/// code
}
finally
{
if (a != null) ((IDisposable)a).Dispose();
}
===
It's the C# compiler that translates every using() to something like the
above code. The IDisposable.Dispose method on data providers automatically
rolls back any open and uncommitted transactions so you don't need to do
explicit rollbacks.
BTW. I've seen many (MS and other) examples where they don't call Dispose
the IDbCommand object, even though it implements IDisposable, I'm not sure
whether it leads to potential resource leaks or not.

[Mono-list] Datawindows
I've been Working on a Data Bound DataGrid that is based on Gtk# Widgets (Scrolled Window, TreeView, ListStore, Cellrenderer). It uses the WinForms DataGrid paradigm for for consuming Data providers, it's a work in progress (although it is sufficiently useful for my needs as it is). You are welcome to the code for it. I will be developing other DataBound Controls as I go.

Then sure you know about the functionality and power of its Datawindow Control. My question was if there is anything similar usable yet under mono or any other GPL development platform, or free at least. Any control or widget with similar power to Poweruilder DW? I know Winforms will have a DataGrid control, but, I don't know about its real functionality and power, and I don't know about its timing roadmap for use it in production envirnoment.
