Eureka! SoapExtension problems solved! - Jan Tielens' Bloggings

This guy had my same problem. I'm recording this here for posterity's sake.

Eureka! SoapExtension problems solved! - Jan Tielens' Bloggings: "Maybe you've read my post about the problems I had while using a custom SoapExtension class. Thanks to an anonymous reaction, I found the sollution!! I was testing the webservice by using the default test page from Internet Explorer, but the testpage in IE uses the GET protocol, not the SOAP protocol. So there was nothing wrong with my code (I started believing I really sucked ;-), I only had to make a very simple test application. Thanks again to the person who submitted this tip!"

ASP.NET.4GuysFromRolla.com: Exception Handling Advice for ASP.NET Web Applications

ASP.NET.4GuysFromRolla.com: Exception Handling Advice for ASP.NET Web Applications:

Excerpt:
"The Crib Notes
My advice for handling exceptions in an ASP.NET application can be boiled down to the following guidelines:
  • Create and use a meaningful custom error page.
  • In general, do not catch exceptions. Let them bubble up to the ASP.NET runtime. Some cases where catching an exception makes sense include:
    • When there is a plausible way to recover from the exception by performing some alternative logic,
    • When a peripheral part of the application's workflow throws and exception and that exception should not derail the entire application, and
    • When you need to include additional information with the exception by throwing a new exception that has the original exception as its inner exception.
  • Log all exceptions to some persistent store and use email (or some other medium) to notify developers when an exception occurs in production. Consider using ELMAH or ASP.NET's built-in Health Monitoring system to facilitate this process.
Read on for a more in-depth look at these suggestions."

How to Make Your ASP.NET Third Party Component 10x Faster > Web/Cloud Applications Development Platform > White Papers

How to Make Your ASP.NET Third Party Component 10x Faster > Web/Cloud Applications Development Platform > White Papers:

I wonder how well this works. I tried making a control using Visual WebGui, but it was extremely expensive to load up a hundred of them on one page (yes, that's my requirement).

"The following document will explore the basics of enhancing 3rd party ASP.NET components performance by leveraging the Empty Client (an ASP.NET extension) pipeline.

1.1�What is the Empty Client?
This architecture is an emerging open source methodology which offers a different approach to architecting, developing and deploying AJAX applications. In order to shed some light on this methodology, we will compare it to the classic Thin and Thick (also referred to as Fat or Smart) client approach and to traditional AJAX structures. Empty Client offers a new balance between the Thin and Thick client approaches and a new channeling of the AJAX calls."

Making Sense of ASP.NET Paths

Making Sense of ASP.NET Paths: "ASP.Net includes quite a plethora of properties to retrieve path information about the current request, control and application. There's a ton of information available about paths on the Request object, some of it appearing to overlap and some of it buried several levels down, and it can be confusing to find just the right path that you are looking for."

How to commit in Git when there are "suspicious patch lines" with trailing whitespace

Try the following:

1. Stage desired files using "git add" or "git add -p" or "git gui" or "git citool" etc.
2. Use "git commit --no-verify"

Actually, was this really worth a blog post? Since this blog acts to augment my memory, I guess it does.

ASP.NET 2.0: Playing a bit with GridView "Sort Grouping"

ASP.NET 2.0: Playing a bit with GridView "Sort Grouping":

Thank the Lord!

"I am on bit experiment mood today, so I did a little tryout to see what it requires to add so called "sort grouping" into GridView. E.g when you have tabular data in GridView and you sort it based on some criteria, you'd want to better express those distinct items, based on which the grid is sorted. Here's a few screenshots of what I did, to demonstrate what I mean."

A few ASP.NET 2.0 GridView Sorting Tips and Tricks

A few ASP.NET 2.0 GridView Sorting Tips and Tricks:

From an old Scott Guthrie blog post from 2006. This seems to be exactly what I need to revamp the GridView that I'm working on! I'm also having good results with GaiaWare.

"I saw a few interesting posts today that talked about ways to implement some sorting tips and tricks with the ASP.NET 2.0 GridView:

Mike has a nice post that walksthrough how to implement custom bi-directional sorting with the GridView. Souri uses a similar approach to implement multi-column GridView sort semantics.

Teemu then has a cool post that shows how to implement 'sort grouping' where you can sub-group/band row values within the GridView:

Hope this helps,

Scott"

Git Recipe for magical, mysterious end-of-line problem with Git status

Ok. I really don't understand this. Occasionally file operations will result in Git complaining that some files are different when nothing apparently has changed. This weird recipe seemed to fix the problem in a way that I do not understand.

Problem
git diff shows the every single line of the file as changed, but git diff -w (i.e. ignore all whitespace) shows the file as changed, but shows no lines as changed.

Solution
1. Type this command to temporarily turn off CRLF automagical conversions:
git config core.autocrlf false; git config core.safecrlf false

2. Refresh the view in Git gui. There will be no changes indicated anymore.
3. Type this line to temporarily turn CRLF automagical conversions back on:
git config core.autocrlf true; git config core.safecrlf true
4. Possibly repeat more than once, staging and un-staging in the mean time. Like I said, it's a mystery.

NOTE: I've only done this once. I haven't tested it multiple times. I'm just posting it here for posterity's sake in case I need to try this recipe again.

A generic way to find ASP.NET ClientIDs with jQuery - Rick Strahl's Web Log: "I’ve been using a small hack to deal with the ASP.NET naming container morass that is so prevalent in client side development with ASP.NET. Particularly in Master Pages all server control IDs are basically munged because the master page place holders are naming containers."

At the end of the article is this gem that might help me optimize the Vendor Web page:

  2. How do you approach dependencies that might be used, but may be expensive to create?
  3. How to build object graph of MyClass considering the fact that any of those dependencies can have their own dependencies etc."

Installing Debian Testing from Netinst or Business Card

  1. Install Debian kind of minimally, i.e. without Desktop. (I still did "standard install".)
  2. Reboot.
  3. Edit the apt configuration to point to testing:
  4. vi /etc/apt/sources.list
    :%s/lenny/testing/g
  5. Save the file.
  6. Run the following command to update the apt sources after aptitude update:
  7. aptitude update
  8. Run the following command to upgrade the system to testing:
  9. aptitude safe-upgrade
  10. Run the following command to install the desktop environment:
  11. tasksel install desktop
  12. Optional: run tasksel install again for file server and web server, which I need in my scenario for Git.

Functional Programming for Everyday .NET Development

From MSDN Magazine, October 2009.

Object Hydrator - .NET test data project

This looks pretty cool. I discovered it through The Morning Brew blog, I think.
"Project Description
This project allows you to pass custom POCO's to it, and have it return an instance of the class populated with randomly generated data.

So basically, you create a class and decorate the property with the name of a Generator you want to use. Pass the object to the Generator and it returns it filled with data. The idea behind it is to use it to replace a database call to use in your UI. "

Why Git?

Why Git? - great article by Ayende @ Rahien, with a very good discussion that follows. Also it's fairly recent -- 19 days ago.

Yet another Git versus Mercurial article

This one's well-written and the comments that follow are not shrill but intelligent. The author claims that Git is like MacGyver, while Mercurial is James Bond. (A commenter claims that Git is more like the A Team, but hey.) One commenter does a great job describing the attitude of the Git community towards Windows users. In a word, contempt. The thing is, I'm a power user who loves Git, and when I first examined it back in the fall of 2007, it just seemed like a better project for Windows. I'm wondering if I should reevaluate.

How XML Threatens Big Data : Dataspora Blog

How XML Threatens Big Data : Dataspora Blog

Fascinating article. He talks about why XML is philosophically wrong for huge datasets ("Big Data"). I found this article while looking through an HR-XML blog.
"We had a deadline to meet (and, mon dieu, a 35 hour work-week). So we changed course. We hacked our Perl scripts to emit a flat tab-delimited format — “TabML” — which was bulk loaded into Oracle. It wasn’t elegant, but it was fast and it worked.

Yet looking back, I realize that XML was the wrong format from the start. And as I’ll argue here, our unhealthy obsession with XML formats threatens to slow or impede many open data projects, including initiatives like Data.gov.

In the next sections, I discuss how XML fails for Big Data because of its unnatural form, bulk, and complexity. Finally, I generalize to three rules that advocate a more liberal approach to data."

The truth about HR-XML

One guy says it's a bunch of BS. Another guy says it's a fig leaf to cover up for lack of interoperability. Finally, there's a former member of the HR-XML consortium who has some things to say about it.

Here's an older post by the same author: HR-XML Integration in Human Resources Software.

Converting ASMX to WCF Web Service - Stack Overflow

Converting ASMX to WCF Web Service - Stack Overflow: "I need to upgrade our web services to use WCF instead of ASMX. If the signatures of the web services stays the same, will existing clients that already call the ASMX service have to change anything on their end? Is there anyway to still use WCF but not force them to change anything?"

The answer is simple. I tried it and it worked. I did have to change the server binding config to be the custom binding created by svcutil.exe. But since that utility creates the configuration, it's basically a cut-and-paste job.

Configuring AnkhSVN revisited

Turns out they got rid of the Tools/AnkhSVN menu option. It's now integrated all over the place. The configuration I was looking for is in Tools/Options/Source Control. Never mind that I spent several hours hunting down the configuration by reading source code. Arg!

Configuring AnkhSVN 2.1.7141.181 when the configuration dialog does not appear in Visual Studio

For some reason my Visual Studio does not display a menu option to configure AnkhSVN 2.1.7141.181, so below are the registry settings to configure it to use TortoiseSVN. But first, a list of the settings.

Setting NameDescription
MergeExePathPath of the executable used for merging, including all arguments.
DiffExePathPath of the executable used for diffing two files, including all arguments.
PatchExePathPath of the executable used for applying a patch, including all arguments.
InteractiveMergeOnConflictIf true, launch an interactive merge on a conflict. Default value is false.
FlashWindowWhenOperationCompletesIf true, window flashes when operation completes. Default value is false.
AutoAddEnabledIf true, new project files are automatically marked for adding to Subversion. Default value is false.

Following is a .reg file containing registry settings to use TortoiseMerge for all diff, merge, and patch operations:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\AnkhSVN\AnkhSVN\VisualStudio\8.0\Configuration]
"DiffExePath"="$(HostProgramFiles)\\TortoiseSVN\\bin\\TortoiseMerge.exe /base:\"$(Base)\" /mine:\"$(Mine)\" /basename:\"$(BaseName)\" /minename:\"$(MineName)\""
"PatchExePath"="$(HostProgramFiles)\\TortoiseSVN\\bin\\TortoiseMerge.exe /diff:\"$(PatchFile)\" /patchpath:\"$(ApplyToDir)\""
"MergeExePath"="$(HostProgramFiles)\\TortoiseSVN\\bin\\TortoiseMerge.exe /base:\"$(Base)\" /theirs:\"$(Theirs)\" /mine:\"$(Mine)\" /merged:\"$(Merged)\" /basename:\"$(BaseName)\" /theirsname:\"$(TheirsName)\" /minename:\"$(MineName)\" /mergedname:\"$(MergedName)\""

[HKEY_CURRENT_USER\Software\AnkhSVN\AnkhSVN\VisualStudio\9.0\Configuration]
"DiffExePath"="$(HostProgramFiles)\\TortoiseSVN\\bin\\TortoiseMerge.exe /base:\"$(Base)\" /mine:\"$(Mine)\" /basename:\"$(BaseName)\" /minename:\"$(MineName)\""
"PatchExePath"="$(HostProgramFiles)\\TortoiseSVN\\bin\\TortoiseMerge.exe /diff:\"$(PatchFile)\" /patchpath:\"$(ApplyToDir)\""
"MergeExePath"="$(HostProgramFiles)\\TortoiseSVN\\bin\\TortoiseMerge.exe /base:\"$(Base)\" /theirs:\"$(Theirs)\" /mine:\"$(Mine)\" /merged:\"$(Merged)\" /basename:\"$(BaseName)\" /theirsname:\"$(TheirsName)\" /minename:\"$(MineName)\" /mergedname:\"$(MergedName)\""

Here is the file AnkhDiff.Tools.cs that contains all the settings. Look for the functions GetDiffToolTemplates(), GetMergeToolTemplates(), and GetPatchToolTemplates().

When putting these into the registry by hand, make sure to change all single quote with a double quote. (There must be code in AnkhSVN that already does this.)

5 ways to answer managers' unfair software test, QA questions

5 ways to answer managers' unfair software test, QA questions: "About 20 years ago Tom DeMarco defined the unfair software question with his article, Why does software cost so much?. DeMarco claims it is not a question at all, but an assertion or a negotiating tactic. These questions also come up in software testing. Here are a few of my favorites:
'Why didn't QA find that bug?'
'Why is QA always the bottleneck?'
'Why do we have so many bugs?'
'What can we do to improve throughput from QA?'
'Are we done testing yet?'

Taken at face value, these may appear to be fair questions. But let's look at the assertions that are hidden inside of them:

'QA should have found that bug.'
'QA is the bottleneck.'
'We have too many bugs.'
'Testing is taking too long.'
'Testing should be finished by now.'"

How to display an assembly in the "Add Reference" dialog box

How to display an assembly in the "Add Reference" dialog box: "When you are developing a class library, you may want Visual Studio .NET to list your library in the Add Reference dialog box on the .NET tab without the user having to browse for it.

This issue is not resolved if you install your assembly to the global assembly cache, because the Add Reference dialog box is path-based and does not enumerate the components from the global assembly cache."

Use Case/Project Management Stuff

Some musings/notes.

OpenUP -- their developer and tester stuff is cool. Also the risk management, and the prioritization (like kanban). The Powerpoint was very good.
Use Case structure -- see the wikipedia article for things to include.

Alistair Cockburn's points:
  • Structure use cases with goals.
    • Non-functional requirements can be attached to goals.
  • Goals have levels - high, low, overarching, short-term detailed, etc.
  • Include Stakeholders and Interests - helps separate the wheat from the chaff
  • Levels:
    • Brief - 2-4 sentences, for instance in a spreadsheet cell
    • Casual - a few paragraphs
    • Fully dressed - long template, include stakeholders, minimum guarantees, postconditions, business rules, performance constraints, etc.
  • Alternative behaviors are more important than the main scenario!! For instance, they reveal subtle requirements.
  • Do not use UI elements!
  • His resources, templates, etc.
Long use case structure, probably for the detailed view:
  • Name
  • Version
  • Goal - very important
  • Summary
  • Actors
  • Precondition
  • Triggers
  • Basic course of events
  • Alternative paths -
  • Postconditions
  • Business Rules
  • Notes
  • Author and Date

Shrinking ViewState when using dynamic controls in ASP.NET

"For 'static' controls (meaning controls declared in your .ASPX page) the ViewState carries VERY little overhead, if any at all. Though for Dynamically Created controls the situation is a bit different. Very often when you create Dynamic Controls this is a three phase run:
  • Instantiate the Controls
  • Set its values
  • Add it either directly or in-directly to the Page object
"IF you follow the EXACT same steps in the given sequence as the above list, then your ViewState object will be SIGNIFICANTLY reduced in size! This is also true for ALL WebControls and not only Gaia Ajax Widgets.

"The reason is that when your dynamically created Controls are being added to the page object then its complete lifecycle will execute which means that among other things the ViewState 'IsDirty' flag will be set to TRUE. When the ViewState IsDirty flag is set to true, then all properties you modify afterwards will have its values stored in the ViewState object. If you however set those properties BEFORE adding the Control to the Page object then the ViewState will not be dirty for those properties and values."

dave^2 = -1: An introduction to the SOLID principles of OO design

He makes this stuff more comprehensible than Robert Martin, who is the creator of the acronym.

dave^2 = -1: An introduction to the SOLID principles of OO design: "I would be very hard pressed to go passed [sic] Robert 'Uncle Bob' Martin's SOLID principles as the single most useful tool for helping me with OO design. Some people seem to have a natural talent for OO design and thinking, and have an innate understanding of these principles without requiring the SOLID formalism. I, on the other hand, find them indispensable.

"Unfortunately the names used in the somewhat-cryptic 'acronym of acronyms'[1] don't exactly lend themselves to being easily learned (Bob Martin and Scott discussed how this came about on a Hanselminutes episode on SOLID, which is well worth a listen). I thought I'd post my interpretation of the principles as a refresher for myself, and as an introduction for anyone trying the learn the terminology."

Peter Van Roy: Programming Paradigms for Dummies

To quote Lambda the Ultimate:
This chapter gives an introduction to all the main programming paradigms, their underlying concepts, and the relationships between them. We give a broad view to help programmers choose the right concepts they need to solve the problems at hand. We give a taxonomy of almost 30 useful programming paradigms and how they are related. Most of them differ only in one or a few concepts, but this can make a world of difference in programming. We explain briefly how programming paradigms influence language design, and we show two sweet spots: dual-paradigm languages and a definitive language. We introduce the main concepts of programming languages: records, closures, independence (concurrency), and named state. We explain the main principles of data abstraction and how it lets us organize large programs. Finally, we conclude by focusing on concurrency, which is widely considered the hardest concept to program with. We present four little-known but important paradigms that greatly simplify concurrent programming with respect to mainstream languages: declarative concurrency (both eager and lazy), functional reactive programming, discrete synchronous programming, and constraint programming. These paradigms have no race conditions and can be used in cases where no other paradigm works. We explain why for multi-core processors and we give several examples from computer music, which often uses these paradigms.
The concurrency stuff looks interesting.

Rio by Vice Magazine




Ask any self-respecting carnivore what to eat in Rio, and they’ll tell you about the rodizios. A rodizio is more than just a meal, it’s an elaborate battle of wits between you and the doe-eyed service staff, as they waft meat under your nose. You indicate your desire to stick or twist with a doublesided card; green meaning “feed me” and red meaning “get away from me, peasant.” Also, when in Rio, don’t forget to find a juice bar, and ask for an a├žai smoothie. It might look like something Barney the Dinosaur would leave in the toilet, but the Amazonian berries served with ice eradicate all traces of a hangover you got from drinking too much Brahma beer in approximately 30 seconds.



For a true carioca sleeping experience, head in search of the notorious love motels. Paid by the hour, motels are as ubiquitous and well-frequented as churches, with each one even given an individual star rating for their level of service. For a dollar or two per hour, you get your bog-standard plastic sheets and herpes on tap, but if you want to quite literally splash out, the five-star deluxe motels have heart-shaped water beds, sex harnesses, a hot-tub fit for a futebol team and gimp-suits on room service.



Forget hanging out, spend as much time and money as you can buying as much cheap tat as you can get. It’s best to avoid the enormous identikit shopping malls, and take to the streets if you want some weird stuff. Also, look out for the dudes selling racks of bootleg funk carioca CDs. The thrift shops of Lapa are the place to go for the Bonde Do Role look. You can also put together a nice collection of vintage Playboys, which, if you’re lucky, will have had just one careful owner.



In the south zone, there’s a small handful of underground clubs, such as Moo, Dama De Ferro and Fosfobox where you can join an invariably tattooed and bisexual crowd in watching big name DJs or, if you’re really lucky, Madoninha. She’s a blonde dwarf who sings literally translated renditions of Madge classics, such as “Como uma virgem. Oh!” If you want to learn more about “ginga”, the fluidity and movement of Brazil, watch the short film Movimento at brahma.com

Very important point regarding the essence of Kaizen (emphasis added):
Much of the success of Kaizen came about because the system encouraged many small-scale suggestions that were cheap and quick to implement. They also came from shop-floor employees - who had a detailed appreciation of the benefit each change might make to the process concerned. By implementing many small improvements, the overall effect was substantial.

Their communication link has the following important point on communication, which point may have been missing from the communication team project charter:
Co-ordination of departments, teams and groups - e.g. making sure that marketing, production and administration know what each other is doing, when and why

Multiple IE Versions revisited

I wrote a while back about installing multiple versions of IE on your computer. Since IE 8 came out, I went back to the site to see if it had been updated. It hadn't, but a commenter on the site posted this link: http://finalbuilds.edskes.net/iecollection.htm

I haven't tried it yet, however.

Using Script# with ASP.NET

Random notes on this topic.
  • Follow instructions here on wiring up the control, specifically the parts about implementing IScriptControl, and overriding OnPreRender() and Render(). However you *must* make one crucial change, or else you'll break ALL javascript on the page.
    • You must change this line as follows:

    • Before:
          var descriptor = new ScriptControlDescriptor("namespace.class", this.ClientID);
      After:
          var descriptor = new ScriptControlDescriptor("namespace.class", someOtherControl.ClientID);
      The problem is that user controls do not, per se, have an associated HTML control, so it's necessary to place the control's contents inside a Panel. If you do try to create a descriptor using "this", the un-handled error resulting from the $create() call on the client will cause all page-initialization-related Javascript that runs after that point to fail, thus breaking the page in a big way.

GWT Designer, ScriptSharp, Ext JS

Some AJAX things I've been eyeing. Microsoft AJAX just isn't good for certain things, although it's nice.

Asp.Net Session Timeout control

Works with AJAX too.

This is pretty cool. It truly is just something you drop onto the page and configure.

http://weblogs.asp.net/latishsehgal/archive/2008/08/29/asp-net-session-timeout-control.aspx

The blog post describes an important change, but he documents it rather poorly. The changes he describes must be made to the “Timeout.js” script.

NYTimes: Job Losses Hint at Vast Remaking of Economy

History happens in slow motion. This article looks like it's eerily foreshadowing the future. We go about our lives, worried about the situation around us, but the world is the same for the most part. After 9/11, everyone talked about how everything would change, yet the world continued as it did before. Irony did not die. But I think that the changes happening now will dwarf the post-9/11 changes that everyone was predicting at the time.
From The New York Times:

Job Losses Hint at Vast Remaking of Economy
By PETER S. GOODMAN and JACK HEALY

With unemployment at 8.1 percent, some economists believe that a wrenching restructuring is under way....

How to determine iPhone firmware version

This didn't work for me. Brought up tons of diagnostics, but no version.
"How do I find out what firmware version my iPhone is?

You don't actually need to know this in order to unlock your iPhone with us, as our software works with all current iPhone firmware versions, but to check yours - simply dial *3001#12345#* then press the call button, compare your Modem version to the table below to find out your firmware version:

1. 04.04.05_G - OTB 1.1.4 iPhone
2. 04.03.13_G - OTB 1.1.3 iPhone
3. 04.02.13_G - OTB 1.1.2 iPhone
4. 04.01.13_G - OTB 1.1.1 iPhone"

ASP.NET AJAX partial update does not work with xhtmlConformance tag in web.config

What a pain! I spent hours troubleshooting this.

I converted a .NET 1.1 application to .NET 2.0. The web.config had this section:
  <system.web>
...
<xhtmlConformance mode="Legacy"/>
...
</system.web>

When I removed the xhtmlConformance tag, it began working again.

Economy Made Few Gains in Bush Years

"President Bush has presided over the weakest eight-year span for the U.S. economy in decades, according to an analysis of key data, and economists across the ideological spectrum increasingly view his two terms as a time of little progress on the nation's thorniest fiscal challenges."

And yet there are those who will worship Dubya until the day they die. How can you take seriously any supposedly religious person who believes that Dubya was sent by God? Maybe he was sent by God to punish us for something -- like to punish us for voting Republican.

Developing a use case document, looking for guides or software to help

On StackOverflow.com, someone asked about a good reference guide and templates for writing use cases. The person with the best answer talked about Alistair Cockburn, and mentioned this document as well, which I haven't read yet: http://www.bredemeyer.com/pdf_files/functreq.pdf
