I just found out that the .NET Reflector asks me two questions.
The first is this:
- This version of .NET Reflector is out of date. Do you want to update automatically?
(YES / NO)
If I answer NO, then reflector quits, so I’m forced to answer YES.
(the question seems wrong: if you don’t have a choice, then why pose a question?)
When answering YES, you get a message box like this:
After pressing OK, automatically a browser screen opens at this url: http://www.red-gate.com/products/reflector/
That page is an advertisement for the new version 6.0:
NEW: The .NET Reflector download now includes a 14-day, free trial of .NET Reflector Pro.
So the situation now seems this:
- You are forced to upgrade to the new Reflector
- You have to perform this upgrade manually
- It is not possible to install .NET Reflector 6.0 without the trial: when running it, it automatically installs the trial in Visual Studio.
So, 20 months after RedGate acquired Reflector from Lutz Roeder, it seems the new Reflector became a kind of ad-ware.
Did it? Did it not?
That and the impossibility of an automatic update makes me having mixed feelings. It seems I’m not the only one.

I just found out that the sourcecode tag in WordPress now supports even more languages.
This is the list of languages is below, it contains links to Wikipedia for each language.
Starred ones (bold and hyperlinks in this theme are the same ) are new since my post last year.
This is a follow up on the original article Including formatted sourcecode in WordPress « The Wiert Corner – Jeroen Pluimers’ irregular stream of Wiert stuff.

Google published an interesting graph generated from their internal data based on their indexed web pages.
A quick summary of popular encodings based on the graph:
- Unicode – almost 50% and rapidly rising
- ASCII – 20% and falling
- Western European* – 20% and falling
- Rest – 10% and falling
Conclusion: if you do something with the web, make sure you support Unicode.
When you are using Delphi, and need help with transitioning to Unicode: contact me.

* Western European encodings: Windows-1252, ISO-8859-1 and ISO-8859-15.
Reference: Official Google Blog: Unicode nearing 50% of the web.
Edit: 20100212T1500
Some people mentioned (either in the comments or otherwise) that a some sites pretend they emit Unicode, but in fact they don’t.
This doesn’t relieve you from making sure you support Unicode: Don’t pretend you support Unicode, but do it properly!
Examples of bad support for Unicode are not limited to the visible web, but also applications talking to the web, and to webservices (one of my own experiences is explained in StUF – receiving data from a provider where UTF-8 is in fact ISO-8859: it shows an example where a vendor does Unicode support really wrong).
So: when you support Unicode, support it properly.

Recently, I had an issue while validating XML with XSD: validation in .NET using the built in classes in the System.XML namespace, and validation in native Windows using the COM objects exposed by MSXML version 6 (which incidentally ships with the .NET 3.0 framework).
Some documents validating OK in .NET did not validate well with MSXML.
I’ll show my findings below, and try to explain the difference I found, together with my conclusions.
The main conclusion is that MSXML version 6 has a bug, but I wonder why I can’t find much more information on it.
Since there is not so much ready to use for validating XML by XSD in .NET and native, I’ll include complete source code of command-line validations applications for both platforms.
.NET source code is in C#.
Native source code is in Delphi.

Finally someone who explains this topic well: CodeProject: Multi-Threading in ASP.NET.
Most of it is based on Web 405 “Building Highly Scalable ASP.NET Web Sites by Exploiting Asynchronous Programming Models” by Jeff Prosise, which should be here on the Microsoft events site (which currently has connection problems) and is referenced here and here.
Recommended reading!

Getting different architectures to talk can be a pain, even when using standards like SOAP.
In this case, the .NET WSDL imports Delphi generated WSDL in a different manner than you’d expect at first sight: when having both an ‘out’ parameter and a function ‘result’, the ‘result’ is not imported well.
But alas: SOAP didn’t accommodate for this situation in the past, and now SOAP now has some additions to solve this.
Bruneau Babet explains this here: [WayBack] SOAP inconsistency? Delphi 2010 (Win32) Server and .NET Client swapping ‘out-parameter’ and ‘result’. – Stack Overflow.
There he explains how to use the parameterOrder attribute, which the Delphi WSDL importer and exporter still do not support.

I always forget the pragma syntax, because it differs substantially from the #if syntax, and I hardly use #pragma.
Contrary to #if … #endif, there is no #pragma … #endpragma.
Instead, there is #pragma warning disable ### … #pragma warning restore ###).
Ken Evans wrote a nice blog article about it (a long time ago, but it is still current): Kirk Evans Blog : Suppress warnings in C# 2.0.
And of course: the official docs, which indicate that when you omit the warning list in a #pragma warning restore, then all warnings are restored.
You can get the error numbers from the compiler output window (no, the errors/warnings/hints window does not show the numbers, that would be to obvious).

Gerrit Beuze just announced the new beta of ModelMaker Code Explorer 8.
For me, ModelMaker Code Explorer (especially at a price of only EUR 99!) is an indispensable tool for both creating new sources, and maintaining old sources (the refactorings it can do are awesome, but there are many other useful features in it as well).
Over the years, I’ve been using interfaces in Delphi more and more.
Actually, in some of my projects almost all classes implement interfaces.
Therefore, I’m particularly glad with the new feature ‘auto complete style drop down list’ in the ‘Edit Class dialog’ that this beta brings.
More info: ModelMaker Code Explorer 8.02 beta.
Note: if you use Visual Studio, there is a Visual Studio edition of ModelMaker Code Explorer too.

Today, I bumped into something utterly strange: requests replayed through Fiddler 2 to a locally running ASP.NET Development Server on Vista using localhost URLs did not give a connection.
I use ASP.NET from both C# and Delphi Prism. Most of my development work is on Windows XP (see notes below) but I test on many platforms.
Moving one of the projects from XP to Vista, and testing with Fiddler, I found that when using Fiddler 2:
This form of URL fails on Vista, but works on XP: http://localhost:49703
This form of URL works both on Vista, and XP: http://127.0.0.1:49703
So on Vista – contrary to XP – localhost requests from Fiddler were in fact being sent to the external network adapter on Vista, and the 127.0.0.1 requests to the internal network adapter.
Since the ASP.NET Development Server is bound only to the internal network adapter, external requests don’t work (boy, I wish they did, it would make some of my debugging so much easier!).

This just had this happen on a Windows 2003 server with a client’s client.
Any .asmx page would return a 404 error like this IIS log line shows:
2009-11-06 09:46:05 127.0.0.1 GET /MyVirtualDirectory/MyWebService.asmx – 80 – 127.0.0.1 Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.2;+SV1;+.NET+CLR+1.1.4322;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.4506.2152;+.NET+CLR+3.5.30729) 404 2 1260
Searching for “iis 404 2 1260 asp.net” found this top from Marc Valk, that solved the issue: ASP.NET v2.0.5727 was prohibited to run.
Which means that none of the ASP.NET bound extensions would work: they all returned 404 errors.
(Note: if you are wondering where your IIS log files are, this post shows you).
