An interesting question on Stackoverflow.com: .net – Different WSDL ASMX,WCF web-services – Stack Overflow.
The answer is simple when you know it: flatten the WSDL that comes from WCF.
Note that Delphi Win32 is not the only client having these issues, as Elton Stoneman shows on his blog and the WCFExtras toolkit for WCF that allows for single WSDL export.

When using wget for downloading from the command-line, sometimes you need cookies in netscape file format.
There is a Chrome cookie.txt export extension that makes exporting your cookies in that format easy.
It opens a window that contains the cookies relevant to the domain of the currently opened web-page. You copy/paste your cookies in format like this:
# Cookies for domains related to wordpress.com.
# This content may be pasted into a cookies.txt file and used by wget
# Example: wget -x --load-cookies cookies.txt https://wiert.wordpress.com/wp-admin/post.php?post=5767&action=edit
#
en.forums.wordpress.com FALSE / FALSE 1304919940 TESTCOOKIE home
en.support.wordpress.com FALSE / FALSE 1304920249 TESTCOOKIE home
wiert.wordpress.com FALSE / FALSE 1304920561 TESTCOOKIE home
en.wordpress.com FALSE / FALSE 1304920572 TESTCOOKIE home
It even includes the wget command-line example for loading the cookies using the –load-cookies option :)

Sometimes you want to know the Windows Version and Service Pack number.
A GUI version is very simple: run winver.exe, it will give you dialogs like these ad the Microsoft Knowledge Base article 310104 explains.
A console version can be done in several different ways:

When you are using Team Foundation System (TFS) for version control, the project manager sometimes shows a file as being checked out by someone else, but it doesn’t show who that someone else is.
The reason is that the Project Manager only has generic knowledge about version control systems. However, the Source Control Explorer has specific knowledge about TFS.
So when you look in the Properties Window for the path of the file you are interested in, then you can use the Source Control Explorer to locate the file, and find out who has checked out that file.
There are other tools that can even give your more information than the Source Control Explorer:

I love the Entity Framework, but as with every layer of abstraction, sometimes you need to get underneath in order to solve problems.
For EF questions, I usually browse the presentations, blog, articles or Entity Framework book from Julie Lerman.
I met her first at an SDC conference years ago: she has a great way of explaining new concepts in an easy to grasp way, not being afraid to do a deep dive into technology when needed.
Her article MSDN Magazine: Data Points – Profiling Database Activity in the Entity Framework is a great way to start digging for the actual SQL being executed by EF on your behalf.
It has a balanced list of ways to get that SQL, and describes the pros and cons for each means.
The comments point you to some more ways.
Recommended reading!

MijnAlbum.nl is a popular site for storing and printing photos.
The UX of the site is far below what I’d like so I searched around for some scripts and wrote a bit of code for my own to make it easier.
First a few URL tricks for mijnalbum.nl (with the free demo album with Album ID TYEGMIMD):
The thumbnails frame contains two lists of the photos in the album. Given the demo album, it first contains a this section inside a bunch of JavaScript code:
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-3ANGJPWW.jpg"));
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-6OKRE67M.jpg"));
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-4OSAXTJM.jpg"));
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-7MFJVO4F.jpg"));
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-YQ4BZ4AD.jpg"));
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-3LKQD6AG.jpg"));
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-O8RUL378.jpg"));
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-7TTFUUCG.jpg"));
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-L6SLLZHO.jpg"));
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-YLSWWFJI.jpg"));
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-CFWOY8KK.jpg"));
and further in the page source a HTML table with HTML fragements like these:
<a onclick="resetScrollNextImg();" onfocus="this.blur();" href="index.php?m=albumview&a=1&key=3ANGJPWW&album=TYEGMIMD" target="fotoframe">
<img id="thumb-3ANGJPWW" style="margin-bottom: -3px;" title="Eendjes in de wei" src="http://www.mijnalbum.nl/MiniFoto-3ANGJPWW.jpg" alt="Eendjes in de wei" width="90" height="90" border="0" />
</a>
The HTML fragment has more context (Picture ID in both the a and img tags, Picture description in the alt attribute of the img tag).
You need to parse either of the two tables, depending on what information you are interested in.
I was interested in the thumbnail URL, and the Photo IDs and GroteFoto download URLs because it is way easier to select photos that are bigger. Something like this list:
Thumbnail URL for Album TYEGMIMD http://www.mijnalbum.nl/index.php?m=albumview&a=2&key=TYEGMIMD Photo URLs for Album TYEGMIMD
Since the thumbnail URL page is not xhtml, you have two options:
Though I am not a fan of using Regular Expressions for parsing general HTML, the thumbnail frame is generated in a very consistent way, so in this case I don’t mind using RegEx.
A complete console app is part of the bo.codeplex.com library.
This is the C# code I wrote as a base:
using System;
using System.Collections.Generic;
using System.Text.RegularExpressions;
namespace MijnAlbum.NL.Download.ConsoleApplication
{
public class MijnAlbumNl
{
protected const string ThumbnailPrefix = "http://www.mijnalbum.nl/index.php?m=albumview&a=2&key=";
protected const string BigJpegUrlMask = "http://www.mijnalbum.nl/GroteFoto-{0}.jpg";
private static string DownloadString(string url)
{
var html = string.Empty;
using (var webClient = new System.Net.WebClient())
{
html = webClient.DownloadString(url);
}
return html;
}
protected static string DownloadThumbnailsHtml(string AlbumID)
{
string url = GetThumbnailsUrl(AlbumID);
string html = DownloadString(url);
return html;
}
protected static string GetThumbnailsUrl(string AlbumID)
{
string url = ThumbnailPrefix + AlbumID;
return url;
}
protected static List getPhotoIds(bool dumpGroups, string html)
{
List photoIds = new List();
/* find strings like these:
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-3ANGJPWW.jpg"));
thumbs.push(new Array("http://www.mijnalbum.nl/MiniFoto-6OKRE67M.jpg"));
* RegEx string:
thumbs\.push\(new\ Array\("http://www.mijnalbum.nl/MiniFoto-(?.*?)\.jpg"\)\);
*/
// With @, you only have to escape the double quotes with another double quote: http://weblogs.asp.net/lorenh/archive/2004/09/30/236134.aspx
const string RegExPattern = @"thumbs\.push\(new\ Array\(""http://www.mijnalbum.nl/MiniFoto-(?.*?)\.jpg\""\)\);";
const string PhotoIdRegExCaptureGroupName = "PhotoId";
//const string RegExReplacement = @"${PhotoId}";
MatchCollection matchCollection = Regex.Matches(html, RegExPattern);
// Matches uses lazy evaluation, so each match will be evaluated when it is accessed in the loop
foreach (Match match in matchCollection)
{
Group positionIdGroup = match.Groups[PhotoIdRegExCaptureGroupName];
if (dumpGroups)
Console.WriteLine(positionIdGroup.Value);
photoIds.Add(positionIdGroup.Value);
}
return photoIds;
}
protected static string GetBigJpegUrl(string photoId)
{
string bigJpegUrl = string.Format(BigJpegUrlMask, photoId);
return bigJpegUrl;
}
}
}
Note that others wrote some scripts too, so for instance Kees Hink wrote on Foto’s downloaden van mijnalbum.nl and there is the MijnAlbumDownloader app.
Note 2: The free RegEx Expresso tool is very nice for building and testing Regular Expressions.

Recently, I had a hard-drive fail: no SMART error, the vendor tools didn’t return an error, but HDtune did.
I couldn’t boot from the drive any more, and the partitions were only half visible, so I had a clear indication it should be replaced.
Since the vendor tools couldn’t indicate a problem, I returned it using a generic code, and hoped for a replacement under warranty (based on the HDtune results), and I was glad to receive a free replacement.
So I collected a few links that help you determine when you should not use a HDD any more:

This is post 500 after 2 years and 1 month of blogging here.
When starting this blog, I never estimated the volume would be like this.
So far, the blog has been a great way of meeting new people, something I didn’t anticipate when starting it. Thanks everyone for commenting and teaching me. I’m never too old to learn something new :-)
One thing I did hope for was that the blog would make it easier to find things back. That really works: somehow my blog scores quite well on various search engines. That is only possible when other sites link to me: they apparently do, and I sure hope it is because of the content here. Thanks for linking!
I’m anxious how the blog evolves over the next year: will post # 750 be there? Did the topics change or not?
I’m open to suggestions, so please let me know what you like about this blog, and what direction you would like to evolve it to.
