Re: Async coding pattern

Could you check whether client.GetFooCompleted is null before assigning a

Re: does anyone know a good technique to keep track of your braces in C#?

[Joseph Clark]

Hi Katherine,

When I was just beginning with programming in C#, I found it very helpful
to add a code comment to the line with the closing brace to indicate what
it was closing.  For example:

public void MyMethod(int number, bool value) {
for (int i = 0; i < number; i++) {
if (value) {
DoSomething();
} else {
DoSomethingElse();
} // end "if"
} // end "for"
} // end "MyMethod"

Are you using Visual Studio or similar tool to write your code? "Smart"
tools like Visual Studio can help keep track of this by automatically
inserting braces at the right places, as opposed to writing your code in a
plain text editor.

Re: [OT] Secure page?

[Joseph Clark]

It really depends what the page does.  You could try installer a web
debugger like Fiddler  or
Charles(or look at the network tab in
Firebug or the Chrome inspector) to see
exactly where the page transmits your information to.

Even if the username and password are transmitted securely, presumably
there is some kind of ongoing session identifier being sent to & from your
browser and the non-secure endpoint, in which case you may still be
vulnerable to session hijacking.

Users who compulsively highlight or click text as they read it - are you out there?

[Joseph Clark]

Hi list!

This is a bit of an odd request, but I'm yet to find the right incantation
of search phrases that will yield results from the Internet - hopefully you
can help!

There is a certain subset of computer users who, when reading text on the
screen, compulsively click or highlight text that they are reading on the
screen (I am one of them!).  I didn't even know I was doing it until
someone pointed it out to me whilst I was pairing with them a few years ago.

One of our in-house products recently shipped a new milestone version
internally with a new "feature" when viewing issues that allows you to
instantly edit the content of the fields on the screen simply by simply
clicking on them (turning the plain HTML into editable form controls
on-the-fly). This is pretty neat, but as a serial text-clicker, this
feature is downright infuriating.  I was happy to put this down as either a
little personality quirk of my own, or merely some indication that I may be
insane, but a quick straw poll of those nearby finds at least 3 other
people who have the same behaviour, or some variant (one guy says he clicks
on browser windows a lot as a muscle-memory thing to ensure the right
browser window has focus).

I'm trying to describe to the other team why this new feature sucks for
some people, but I have no idea if that "some people" is one in ten users,
or one in one million.  Have searched a bit online for information about
this, but I don't really know what to search for. Does this user behaviour
have a name? Are there other people like me out there (hello? hello?)? Any
literature around on whether or not its a great idea to bind functionality
to an innocuous user-action like text-selection or clicking in an
apparently non-clickable area?

Cheers!

Re: About Validate Email

[Joseph Clark]

I'm no expert on this either, but I'm fairly certain that this business
requirement is simply not achievable.  Due to the way mail servers operate
on the Internet, there is no way for a sender to know if an intended
recipient address is valid.

An email may go through several mail exchanges before it arrives at the one
that will ultimately deliver to the user's inbox. At any point along the
way, the email may be rejected for any variety of reasons and this
rejection may occur asynchronously.

Playing nicely with ServicePointManager.ServerCertificateValidationCallback

[Joseph Clark]

Hello list!

I have a requirement to relax SSL certification validation on certain web
requests in my application. I know that I can do this by setting a custom
delegate on the ServicePointManager.ServerCertificateValidationCallback
property - which works fine.

The problem I have is that I am not in full control of the host application
- I am writing a plugin package that gets hosted in a 3rd party IIS
application.  Is there a way I can achieve what I'm after whilst still
remaining a 'good citizen' in the host app?

I have written the delegate so that it only performs my custom validation
when it matches the request URI to the URI I expect (otherwise performing
the default check), and I only register the callback for as long as I need
it during the execution of a single method before setting it back to the
original value.  Even so, this is still vulnerable to race conditions if
there is another request executing concurrently, and my code would be
vulnerable to other code overriding the certificate validation callback in
a similar manner.

Any suggestions on how I can make this more robust? Examples and samples
for this API on the Internet are mostly shocking, encouraging developers to
just set the callback and return "true" (ie. no validation) with no
discussion of the pitfalls this entails.

Cheers,
Joe.

Re: 32bit apps

I recall this coming up on the list recently (like in the last 6 months?)

You can try:

* Using the CorFlags
tool to
change the executable headers, but this will invalidate the assembly if it
is signed.

* Launch the app from a 32-bit console, which should only be able to spawn
32-bit processes, I think... haven't tried this myself.

Try using the Assembly Binding log viewer

to see where it is binding the serializer assemblies from (make sure it is

I've been using Ultramon for years for just one single feature - it extends

Re: Good looking WinForms apps

[Joseph Clark]

Steering clear of the "whether or not choosing WinForms over WPF is a good
idea" debate, it's definitely possible to create some nice looking UI's in
WinForms.

The System.Drawing namespace gives you a fairly open licence to do whatever
the heck you want with the window.  Bob Powell has some excellent (a bit
dated, but still applicable) articles on some of the cool things you can do
with GDI+ in .NET (see http://www.bobpowell.net/faqmain.htm).

There are some things you "can't" do (or can't do *easily*), such as doing
matrix transformations or using pretty WPF fonts - but I guess these are the
kinds of things that usually aren't a problem for "line of business" apps.
It's also pretty easy to shoot yourself in the foot with memory leaks, and
it's easy to create performance problems by doing intensive painting or
calculation in the wrong places.

Joe.

Re: 64 bit wcf service library

[Joseph Clark]

Failing that, you could try using Corflags to set the assembly to be 64-bit
compatible: http://msdn.microsoft.com/en-us/library/ms164699.aspx

This has a number of caveats though, most notably the fact that you won't be
able to do this if the 3rd party assembly is strong-named.

JetBrains enters the .NET decompilation business

For those who haven't seen it, looks like the RedGate debacle has given some

Not a direct answer to your question, but although you can't move

Re: Unable to download Sharepoint Foundation from MSDN

[Joseph Clark]

Hi Dave,

I intermittently had the same problem in the past while downloading
SPFoundation, too.  I tried a few times over a 24 hour period and eventually
it worked, so perhaps there is a stale CDN node floating around somewhere.

I had a hunt around for alternative download sites but couldn't find any.

You could try hitting the download link from a tunnelled or anonymised
location, to see if you get served from a different node?

Joe.

Re: Obtaining support hotfixes from Microsoft

Thanks, Chris.  Looks like it's done the trick, too!

@DavidBurstin: Thanks ;-) I did see that blurb, but it seemed
counter-intuitive to me to publicly post details of a bug and fix, but then
make people go through the support system to get their hands on the fix
anyway.  I wanted to make sure that I wasn't missing something glaringly
obvious on the page.

ozdotnet saves the day, yet again.

Obtaining support hotfixes from Microsoft

[Joseph Clark]

Hi List,

I've recently run into some deployment problems on a local SharePoint
server.  A bit of digging reveals a KB article (
http://support.microsoft.com/kb/971521/) as a likely culprit.  The article
says there is a hotfix download available, but either I am blind, the hotfix
is not available for public download, or I have to contact Microsoft to
obtain the patch?

What's the correct procedure here?

Thanks,
Joe.

No, I don't think you're missing anything. I've probably just been soured by

.NET friendly cloud-compute recommendations

[Joseph Clark]

Howdy all,

Does anyone have any experience with Windows/.NET friendly cloud-computing
solutions, specifically for the purpose of farming out compilation and test
agents?

Internally we've semi-standardised on EC2 for all our java-based builds, but
from the literature I've read on the tubes, setting up a Windows image
doesn't sound like very much fun.

I had a brief skim-read on the Azure platform, but it looks like it doesn't
provide any bare-bones infrastructure like msbuild.

Are there any other alternatives?

Cheers,
Joe.

Re: OPen File not working...

[Joseph Clark]

Definitely sounds like it could be an encoding problem.  You could try
replacing this function of yours with
System.IO.File.ReadAllText,
which should attempt to automatically detect the file encoding for you.

Alternatively, open the file in a decent text editor (like Notepad++), which
will be able to tell you the encoding of the file.

Also, have you checked if an exception is being thrown? I notice you are
catching it and printing it to trace output. Any leads there?

Joe.

Re: Recommendations for a ERP system

Hey Andrew,

Shameless plug, but I used to work for Technology
Onein Brisbane.  They're a
home-grown ERP vendor who've been quite successful
in competing locally against the Oracles and SAPs of the world. I know they
have Financials, Payroll & Supply Chain modules in their suite.

I have no first-hand experience in interacting with the products as an
un-biased end-user or customer, but the technology platform is quite sound
and modern by comparison to other ERP suites (.NET WinForms client +
ASP.NETWeb Services).

If you're interested, I should be able to put you in touch with someone in

Re: Retrieve parameters

[Joseph Clark]

Anthony,

You can use the
TargetSiteproperty
on the Exception class to access information about the method that
caused the exception to be thrown... this causes a walk of the call stack,
which has a performance overhead and also may not succeed in all cases,
depending on the situation.

Cheers,
Joe.

Re: Is it me..or is IIS 7 manager a crap interface?

[Joseph Clark]

I found it very confusing after first swapping to it from IIS 6.  Having had
time to adjust, I think it's a pretty good representation of a complex
system.  It's certainly easier to find the settings that were quite
esoteric/hidden away in previous managers.

The one thing I don't like is the swapping between site content/site
features via tabs in the main panel... my brain just doesn't grok it.
Personal preference though, I'm sure!

Re: Method Invoke problem

[Joseph Clark]

The object[] objs array is indicating that the method expects three
parameters, rather than a single parameter which is an array.

You need an array that contains one array :)

object[] objs = new object[] { new object[] {"Hi", 123, DateTime.Now}};

Re: Implement IDisposable?

[Joseph Clark]

Good point, Michael.  I didn't consider the implications of messing with
other objects in the finalizer.  :)

Re: Implement IDisposable?

[Joseph Clark]

I'm no expert, but I understand there is a "proper" way to implement
IDisposable to ensure that things always get cleaned up properly.

Implementing IDisposable allows you to cleanly release your resources as
soon as practical, but relies on the consumer to call the Dispose method
properly.  So, to get around this, you can also define a Finalizer for your
class that performs your cleanup, in the event that IDisposable is not
called.

The problem is that Finalizers have a bunch of caveats attached to them
(related to performance and memory consumption) and thus shouldn't be
defined unless you really, really need them.

So, the trick is to call GC.SuppressFinalize in your Dispose method, which
stops the Finalizer from running needlessly (I don't know about C#, but if
you implement IDisposable in VB.NET, the IDE automatically injects a correct
implementation of this pattern for you).

I did a quick Google search and found a codeproject article which looks
accurate enough and covers it in more detail:
http://www.codeproject.com/KB/cs/idisposable.aspx

Hope this helps.  My knowledge of finalizers is only theory-based.

Joe.

Re: [OT] Does anyone know of any SharePoint developers looking for work in Adelaide?

[Joseph Clark]

I think that as a "general skill" for a .NET developer, familiarity with
SharePoint isn't particularly important.

Developing with SharePoint has a long, moderately-steep learning curve and
in my experience, what you learn isn't particularly transferable to other
areas; it's only useful when you're actually working with SharePoint.  I'm
about 9 months into my first role as a SharePoint dev and I still feel like
I'm barely scratching the surface of what I can "do" with SharePoint.

I haven't used Visual Studio 2010's SharePoint integration yet (because I'm
still stuck supporting MOSS and VS2008), but some of the online demos look
pretty cool.  It reminds me of the stage when ASP.NET development in Visual
Studio was starting to improve with the built-in web server etc. in
VS2005... ie. when they actually started seriously looking at improving the
development experience.

Re: Friday [OT] (Sound Experts) Request for Sound Clening

[Joseph Clark]

I use Audacity  for all my sound editing
(and when I say "all" I mean "the handful of times I have wanted to crop a
segment of a song to use a ringtone" :P).  I'm pretty sure it has a noise
removal function built-in.

I don't think it understands video file formats though, so you'd probably
need some other tool that's capable of extracting the audio stream from the
file.

Re: Web service call problem - The HTTP request is unauthorized with client authentication scheme 'Negotiate'

[Joseph Clark]

Dylan,

If Fiddler isn't working for you, try TCPTrace (
http://www.pocketsoap.com/tcptrace/).  It acts a man-in-the-middle for TCP
traffic, so you don't run in to the proxy problems inherent with the Fiddler
approach.

Joe.

Re: FxCop custom dictionaries

[Joseph Clark]

Here's an interesting blog
articleabout
how Microsoft applies the FxCop rules to some of their own internal
projects.

I read it a few years ago now, so not sure how current it still is, but it
might give you a push in the right direction as to deciding which rules are
useful and which rules are just too painful.

Joe.
