Re: Browser scroll bars

[Chris Anderson]

Try using the IE developer tools to play with the head/body styles in the
page and find out what's causing the issue.

Re: Browser scroll bars

[Chris Anderson]

Currently your browser is set to 110% zoom.  Does it still exhibit this
behaviour if you return it to 100%?

Re: Tracing deployed app

[Chris Anderson]

If you look at the event handler for the UnhandledException of the
Application object in your App.xaml.cs file, you'll see why.  By default,
unhandled exceptions are handled differently when a debugger is attached.

private void Application_UnhandledException(object sender,
ApplicationUnhandledExceptionEventArgs e)
{
// If the app is running outside of the debugger then report
the exception using
// the browser's exception mechanism. On IE this will display
it a yellow alert
// icon in the status bar and Firefox will display a script
error.
if (!System.Diagnostics.Debugger.IsAttached)
{

// NOTE: This will allow the application to continue
running after an exception has been thrown
// but not handled.
// For production applications this error handling should
be replaced with something that will
// report the error to the website and stop the application.
e.Handled = true;
Deployment.Current.Dispatcher.BeginInvoke(delegate {
ReportErrorToDOM(e); });
}
}

Re: Regenerating Ria services metadata

[Chris Anderson]

Regenerating the metadata is really not something I could see being a good
thing.  Those classes are created so that you can apply attributes to
properties on your models without having to mark up the model classes
directly.  Therefore, they're designed to be hand-edited, and regenerating
them would lose any changes (hence regeneration, unless it was done
intelligently to capture the developers existing changes to them, would be
a dangerous feature).  That said, no, I don't know of any existing tools
that do this.

What's your startup project?  The Web project or the Silverlight one?
 Maybe your Silverlight project is set as the startup project, hence the
issue.

Re: Complex region selection

[Chris Anderson]

Well, it's mainly used to demonstrate how much you can customise the
ListBox control using a control template, but you've also got the advantage
of each state being "selectable" using the functionality already provided
by the ListBox control.  I think it's quite a neat way to go about the
problem.

I was wondering where he got the coordinates myself - would be interesting
to know if/when you find out.  My guess is that he used some software to
trace the state outlines and convert them to vectors somehow.

Re: Complex region selection

[Chris Anderson]

How about templating a listbox, as demonstrated here:
http://richapps.wordpress.com/2009/02/12/advanced-styling-wpf/.  That
solution is for WPF, but you could try porting it to Silverlight, and would
solve your US needs out of the box.

October Sydney SDDN Meeting Announcement

[Chris Anderson]

This month we'll have a somewhat informal meeting. I was thinking that it
would be good to have a "show and tell" meeting, where those who are willing
and able can demonstrate some of their work in Silverlight, WP7, WPF, and
LightSwitch.  I've got 2 presentations lined up already (I'll show off the
expanz platform, and hand out beta invites which give you a lifetime
perpetual license).  If you can let me know if you're able to present
beforehand, that'd be great (but not essential).  It'll be a good chance to
see what your peers are building with these platforms, ask them questions,
and inspire you with your own projects!

Please RSVP on our Meetup
eventor
Facebook
event 
.

Hope to see you there!

Sydney SDDN September Meeting

[Chris Anderson]

For those of you wondering about this month's meeting (which normally would
be on tonight according to the normal schedule of the third Monday of the
month), it's been postponed for a week (to the 26th of September) so that we
can get Jose back from BUILD to tell us all the exciting stuff he's learnt,
what XAML's future is in Windows 8, and what other news has finally been
unembargoed.

Of course, the release candidate of Silverlight 5 was also released
recently, so I may talk a bit about that if we have time.

Note that we have a new room at the City Hotel starting this month, with it
being held in the "Emperor Lounge". We meet at 6pm, with a 6:30pm start.

Sorry for the late notice!  Hope to see you there...

Re: Refreshing an SL4 app (client problem?)

It's because the browser is caching the app, and your IIS probably doesn't
set any cache expiry headers.  Here's some info:

Sydney Meeting - August

[Chris Anderson]

This month we have Young Oh presenting on integrating LightSwitch
applications with Silverlight applications (and vice versa). With version 1
of LightSwtich officially being released at the end of last month, this is
the perfect time for this presentation!

*When:* Monday August 15, 2011, 6:00 pm to start 6:30 pm

*Where:* City Hotel
(map)
347 Kent Street (Corner of King Street). Second floor at the Kent Street
Living Room.

*Cost:* Free, but please RSVP on our Meetup
site
.

*Abstract*

Practical guide to LightSwitch for experienced Silverlight developers.
(Integrating a LightSwitch application with a standard Silverlight
application)

Silverlight is great. With Silverlight we are capable of creating data
intensive enterprise online applications using RIA services. But is it
really practical to do so? If the requirements are fixed, maybe yes with
lots of effort. In reality the ground shifts all the time. Everything above
shakes constantly and Silverlight solution may not be acceptable for
practical commercial use.

Then could LightSwitch be the solution? If yes, what could be the problem
with everything LightSwitch approach. Is it possible to combine both? How?
We will try to find a way to combine the best of Silverlight and LightSwitch
for best ROI possible.

- How to put LightSwitch application inside Silverlight application. When.
How. Why?

- How to embed Silverlight modules inside LightSwitch application. Different
methods. What is the limit? Or no limit?

*Bio*

Young is a freelance application developer currently working for various
Qantas / Q Catering projects.

Sydney SDDN - July Meeting

[Chris Anderson]

This month we have Jason Schluter presenting on recreating
http://script.aculo.us/ in Silverlight. We didn’t get to this presentation
last month, so Jason agreed to postpone it until this month.

When: Monday July 18, 2011, 6:00 pm to start 6:30 pm
Where: City Hotel (map) 347 Kent Street (Corner of King Street). Second
floor at the Kent Street Living Room.
Cost: Free, but please RSVP on our Meetup
site
.

Jason’s Abstract:

Light.aculo.us - Recreating http://script.aculo.us/ in Silverlight.

Javascript frameworks are out there to make animation easy. How easy is it
in Silverlight? I?ll run through recreating the effects demos on
http://madrobby.github.com/scriptaculous/combination-effects-demo/ in
Silverlight. Expect Blend, demos, and No talk on Win8!

Jason’s Bio:

Jason Schluter has been a keen Silverlight programmer since Silverlight 1.1
alpha following the rise of Silverlight in huge media and business
application projects, and waiting patiently for the arrival of 3d Support in
Silverlight. Jason currently works as a contractor on a large Silverlight
project and has been building a variety of web projects on the side.

Re: Silverlight object not showing - xap downloading but not launching

[Chris Anderson]

Hi Simon

Hmm, I haven't heard of that issue.  Have you been checking which version of
Silverlight is installed on each of these machines, to see if there's a
common version number across each of them?  Silverlight 4 has had various
GDR releases (one was just released this week), and maybe it's a particular
version with the issue.  If so, you can then modify your HTML page that
hosts the control to require the client machine to upgrade to a minimum
version number from where the problem is solved.

You can check out the GDR release history here:
http://www.microsoft.com/downloads/en/details.aspx?familyid=1b7a3205-b5f8-4e20-bf42-792de5923454&displaylang=en
to
see if the problem has been fixed in a particular release, and Koen Zwikstra
(of Silverlight Spy fame) has a diff list for each version which may or may
not help: http://firstfloorsoftware.com/silverlight-diff-lists/.

Hope this helps...

Chris

Re: Silverlight object not showing - xap downloading but not launching

[Chris Anderson]

Hi Simon

Do you have a custom preloader (i.e. splash screen), or are you using the
default one?  I've personally found that custom preloaders are sometimes
problematic, with similar issues to what you're reporting.  There seems to
be a race condition, where if the Silverlight application downloads too
quickly, the Silverlight runtime gets confused with what it should display
(the preloader or the application), and nothing ends up loading.  I'm
interested in whether other people have experienced this, as I haven't seen
it reported (I do discuss it in my book Pro Business Applications with
Silverlight 4 though).  But then again, sadly few Silverlight developers
actually make the effort to create a custom preloader.  I notice this issue
primarily occurs on development PCs, where the application download
generally does happen fast.  So if you do have a custom preloader, try
disabling it and see if that solves your problem.

[Chris Anderson]

We have 2 speakers this month - Justin King talking about the Microsoft
Media Platform, and Jason Schluter on recreating http://script.aculo.us/ in
Silverlight..

*When:* Monday June 20, 2011, 6:00 pm to start 6:30 pm
*Where:* City Hotel (map) 347 Kent Street (Corner of King Street). Second
floor at the Kent Street Living Room.
*Cost:* Free, but please RSVP on our Meetup
site
.

NOTE: We are looking to use Meetup instead of Facebook for announcing future
events (since some people don't have Facebook accounts).  If you're
interested in Sydney meetings (even if you can't make this one), please sign
up to our Meetup site to get future announcements (Facebook announcements
will be phased out in the coming months):
http://www.meetup.com/Silverlight-Designer-and-Developer-Network/Sydney-AU/155161
.

*Justin's Abstract:*

Microsoft Media Platform – Discovering the video stack of tools

With video streaming and viewing now accounting for 30% of down traffic
bandwidth adding video to your websites is more important than ever.  In
this session Justin will run through the components that make up the
Microsoft Media Platform, MMP Player, Content Manager, Video Editor,
Audience Insight and Expression Encoder.  We will run through adding Smooth
Streaming/Adaptive Streaming to your site and creating a workflow to speed
up the process, as well as adding rich functionality such as Frame Linking,
Analytics and Advertising to pay for the bandwidth you are going to consume.

*Justin's Bio:*

Justin has 15 years Developer/DBA experience in cross platform technologies.
 Currently working with ASP.NET MVC 3 for most projects and a Silverlight
Smooth Streaming for a SQL Server Training website hosted on Windows Azure.

*Jason's Abstract:*

Light.aculo.us - Recreating http://script.aculo.us/ in Silverlight.

Javascript frameworks are out there to make animation easy.  How easy is it
in Silverlight?  I’ll run through recreating the effects demos on
http://madrobby.github.com/scriptaculous/combination-effects-demo/ in
Silverlight.  Expect Blend, demos, and No talk on Win8! ;)

*Jason's Bio:*

Jason Schluter has been a keen Silverlight programmer since Silverlight 1.1
alpha following the rise of Silverlight in huge media and business
application projects, and waiting patiently for the arrival of 3d Support in
Silverlight.  Jason currently works as a contractor on a large Silverlight
project and has been building a variety of web projects on the side.

Re: Silverlight versions

[Chris Anderson]

Have you installed the Silverlight 5 Tools on your dev PC?  It *overwrites*
RIA Services SP1 with the preview of SP2, as per this blog post:
http://jeffhandley.com/archive/2011/04/13/MIX11Releases.aspx.  I'm guessing
your dev machine is therefore targeting SP2.  Of course, the SP2 preview
doesn't have a go-live license (and the installer doesn't give you an option
to not install it).  So my assumption is that any dev PC that's using RIA
Services *should not* install the Silverlight 5 Tools.  I haven't seen this
mentioned anywhere as an issue, but assuming I'm not missing anything this
is a massive oversight, and devs should be warned (or better yet, the SP2
preview stuff should be installed elsewhere).

Re: Bob Muglias & Steve Balmers statements on committment to Silverlight

[Chris Anderson]

It's amusing to see how many times Steve Balmer name dropped 'Silverlight'
in his post :).  Backpedalling ahoy!

My concern from the beginning has specifically been with the phrase “Our
Silverlight strategy and focus going forward has shifted".  Bob says that's
not a negative statement in his post, but I disagree.  Microsoft "shifted"
their strategy away from Windows Mobile, and look what happened with it -
practically nothing for years.  After Microsoft released IE6 their strategy
"shifted" - again work on that product halted for years.  It wasn't like
either of them were perfect, and couldn't have done with more work!

It was easier to brush off Scott Barnes' tweets as those of an ex-softie
that *might not* have the current full picture and strategic insight of
Microsoft, but harder when the controversy stems from the current president
of the Server and Tools division.  You could say that it was simply a bad
choice of words, but added to Scott Barnes' tips starts painting a bad
picture for Silverlight's future.  Stating that their strategy has shifted
sends the wrong message to CTOs, and creates the PR nightmare we are all
faced with now.

Personally, I still have faith in Silverlight and its potential (both
current and future), and evidence showed that Microsoft shares it too
(LightSwitch, Windows Phone 7, etc).  I just hope that Microsoft continues
to see that potential through before chucking it on the backburner, and
doesn't abuse that faith.  Currently they have a rather demoralised
community, and it's going to take a lot to prop it back up.  Because those
of us promoting Silverlight will have a lot more work to do to now promoting
the platform.

If one good thing comes from this controversy, it is that the community has
spoken, and it will *not* be happy with a shift in strategy.  Maybe, just
maybe, that will impact positively internally at Microsoft.

Re: Opening an OOB App

[Chris Anderson]

Ah yes, of course, Silverlight is 32 bit only - for the moment anyway.  And
yep, you could install an app via sllauncher.exe if you have elevated trust
(I didn't think of that).  As you say, the isolated storage solution to
passing parameters between instances has its fair share of issues :).

Re: Opening an OOB App

[Chris Anderson]

%programfiles(x86)% only works on Windows 64 bit unfortunately.  As far as I
know, there's not an easy way to determine this path on both 32 and 64 bit
editions of Windows (unless someone has some tips for doing so).

There's no way of passing parameters to an OOB app unfortunately (AFAIK).
 The only way I know of is to write the parameters as settings in isolated
storage, or to a known location (like, dare I say, the registry if you have
elevated trust).  If it is the same application being loaded, you can write
them to the application store, or if the application to be loaded is from
the same domain then you could use the site store.  If the application
originates from a different domain you're somewhat out of luck, and would
need to use the known location method.

As for your scenario to install another Silverlight application, I can't see
that being possible.  You could always host another Silverlight application
within your application using the WebBrowser control (set up so that if run
within the browser it will only request to be installed, like the Facebook
application does).  You could pass it parameters via the URL query
parameters.  However, the user will always need to be involved in initiating
the actual installation process.  The application will then automatically
launch once installed.

Re: Opening an OOB App

[Chris Anderson]

Yep.  Ideally you'd have an Application.Current.Restart() method, so
elevated trust wasn't necessary though :).  You'd still have to use COM
Interop to find the user's Program Files folder though (the
System.Environment.GetFolderPath method won't return it), and then use COM
Interop to run sllauncher.exe.  Whether it matters that the app is still
running when the new instance is loaded, I don't know, but I think it would
be OK.  I assume the new version (if doing immediately after an update has
been downloaded) will have already been put in the right place, and not
waiting for the current instance of the app to close.  One of us might have
to give it a go as a proof of concept exercise and blog the results :).

Ah, nice.  Will have to remember that one.  Of course you'll need elevated
trust to be able to do that, but looks like a good solution.  Thanks for
sharing Miguel.

September Sydney SDDN Meeting

[Chris Anderson]

Hi All

Here's the details of the upcoming Sydney SDDN meeting.  The event on
Facebook is not up yet, but hopefully it will be soon (please RSVP!).

When: Monday September 20th, 2010, 6:00 pm to start 6:30 pm
Where: City Hotel (map) 347 Kent Street (Corner of King Street). Second
floor at the Kent Street Living Room.
Cost: Free, but please RSVP
What: two great presentations, networking and good discussions over a great
meal and beers.

This month we will have two great presentations - the first on Windows Phone
7 by Nick Randolph, and the second on Visual Studio LightSwitch by Jose
Fajardo. Here are the details.

*The Silverlight Analytics Framework*
*by Nick Randolph*
So you’ve built your first Windows Phone application but do you know if
anyone’s actually using it? Earlier this year Microsoft announced the
Silverlight Analytics Framework and since your Windows Phone application is
written in Silverlight, you should be able to use it! In this session we go
on a quick lap around the analytics framework and how you can use it to
track how, when and where your application is used.

*Lightswitch, should you care or not ?!*
*by Jose Fajardo*
A quick walk thru of a LightSwitch generated Silverlight app. Followed by an
in depth discussion on the wizard process and how this impact’s us as
Silverlight developers as we build our RIA’s manually.

Regards

Chris Anderson

Re: Silverlight RIA Services

[Chris Anderson]

Also try deleting the Generated_Code folder from under your Silverlight
project's folder.  That forces the client side regeneration (which I've
personally found more reliable than cleaning / rebuilding the solution).

Re: Invalid XML (Key attribute fixed)

[Chris Anderson]

Commanding wasn't actually implemented in Silverlight 3, so I'm guessing
that's why you're experiencing the behaviour that you are.  Silverlight 3
had the ICommand interface, but no controls actually supported it (they
didn't have the Command/CommandParameter properties).  So you'd expect
Expression Blend and VS2008 to kick up a fuss.  Instead, you had to use the
Expression Blend Interactivity library, which enabled you to use commands
using attached properties.  However, you say you have it working, which is a
bit confusing.  I'm totally making a random guess here, maybe you have the
Silverlight 4 runtime installed, so even though it's a Silverlight 3 app it
works because commands were partially implemented in Silverlight 4?  I don't
know if that's the case, but it's a possibility.

Re: Out of memory exceptions in VS2010 with Silverlight 4

[Chris Anderson]

Yeah, I have this problem too.  It's damn annoying.  Have you tried just
doing a rebuild of the solution instead of restarting VS though?  That
(often) works for me.  Still, it would be better that it didn't exist as a
problem.

Re: RTF in silverlight

[Chris Anderson]

Hi Steven

I wrote an article (for Silverlight 2, but still valid), which covers
creating an IFrame and displaying HTML/PDF/Word/etc inside it using their
browser plugins:
www.silverlightshow.net/items/Building-a-Silverlight-Line-Of-Business-Application-Part-6.aspx.
 To me, it does look as though it's a part of the application (assuming the
user has the corresponding plugin installed).  It resizes with the browser
window, and you get all the functionality of that plugin (particularly
printing).  Alternatively, check out the Document Toolkit from First Floor
Software (by Koen Zwikstra, of Silverlight Spy fame):
http://firstfloorsoftware.com/documenttoolkit.  It displays XPS, and he
discussed displaying PDF using it too (not sure on the status of that
though).  Check out my example anyway too, and see what you think.  I also
discuss this topic (primarily in regards to reporting) in my upcoming book
Pro Business Applications with Silverlight 4 (for Apress).

In terms of displaying RTF, you might want to look at some open source RTF
parsers in C# like:

http://www.codeproject.com/KB/string/nrtftree.aspx
http://www.codeproject.com/KB/recipes/RtfConverter.aspx

I'm sure it would take little (or no) effort to port to Silverlight.

Hope this helps...

Chris

Re: Validation on non visible datagrid

[Chris Anderson]

How are you implementing validation?  Data annotations, or manually?  If
you're using Silverlight 4 and doing it manually, then Miguel's response is
probably best.  If you are using data annotations, then use the Validator
class to validate the selected item in the DataGrid.  But in Silverlight 3
+ manually, I think you're out of luck (I think, but don't know for sure in
terms of the DataGrid) - handling that sort of situation is just one of the
big problems with the exception based validation model as it was implemented
in Silverlight 2/3...

Sydney SDDN Meeting Reminder

[Chris Anderson]

Just a reminder that the Sydney SDDN meeting is tonight at 6pm (for 6:30).
 If you haven't done so, please register on the Facebook event here:
http://www.facebook.com/event.php?eid=105897519447617&index=1 so we can
order enough pizza.  I'll give a bit of a rundown of the outcomes from
MIX10, and Jose will talk about developing for Windows Phone 7 (or the Zune
Phone as I prefer to call it).

Oh, and bring your external HD / USB keys / laptops / (trying to think of
something suitably silly for this entry, but got nothing at this time of
night), as thanks to Justin King who consumed great slabs of bandwidth to
download all the MIX10 videos (16GB worth apparently, so come prepared) will
have them all available for download off an external HD.  If Justin doesn't
make it then we have a backup of Ewen Wallace (aka @CADbloke) who has
already grabbed them from Justin and will also bring them on an external HD.
 There is a ton of great content there, and is is your best chance to get
them if you haven't got them already and want to reserve your bandwidth for
other potentially less reputable purposes.

And hey, if none of that got your attention, there's free pizza!  See you
then!

Re: Generating Office/PDF documents

[Chris Anderson]

Hi Greg

I wrote an article similar to this topic.  It was back in Silverlight 2, but
most of the concepts still hold.  It involves generating a PDF on the fly on
the server and streaming it through to the client for display in an Iframe
overlaid on your application.  That's not possible in OOB scenarios, but
Silverlight 4 has the WebBrowser control that you could use to display it in
OOB mode.  As Miguel said, you can pretty easily generate a docx file
instead (on either the client or the server) and display it in the Iframe
(assuming the clients have Word 2007 or later installed, or the docx filters
for Office 2003)  - it's actually really easy to do as a docx file is just a
zip file and makes the process really easy.  I once worked with WordML (for
Office 2003), though I'd avoid that if possible, as it's pretty nasty stuff.
 The issue generating reports/documents server side is when the user wants
to print the screen, or populate a report without saving the data back on
the server - although you can find ways to still do that without too much
trouble.  My article here should hopefully help you somewhat:
http://www.silverlightshow.net/items/Building-a-Silverlight-Line-Of-Business-Application-Part-6.aspx.
 Blatant self promotion: I'm currently writing a book called Pro Business
Applications in Silverlight 4 for Apress, due out mid-year.  It covers all
of this sort of stuff, and there is a chapter dedicated to reporting in
Silverlight 4, covering what's in the article above and a lot of the new
features available in Silverlight 4 to support reporting scenarios.

Re: RIA Domain Services and required dependencies

[Chris Anderson]

Try deleting the contents of the Generated_Code folder (it's hidden, use
Show All Files to see it) - sometimes RIA Services stops updating the code
files, but deleting them will get it generating them properly again.  Also
make sure that your custom validation code is in a .shared.cs file so it is
being copied to the client.

Re: Silverlight 4.0 beta

[Chris Anderson]

As a book author for Silverlight, believe me it's hard!  Unfortunately I
don't have inside information either - so I'm left guessing as much as
everyone else with when and what is coming.  Originally my book
(Professional Business Applications in Silverlight for Apress) was due in
December (for Silverlight 3), then it needed to be done by September to be
viable.  It takes several months (about 3-4) from submission to be on
shelves, making it nearly impossible with these rapid release cycles.  As a
developer I love the constant feature additions and rapid growth of
Silverlight, but as an author it's nigh on impossible.

PS. I just looked at the top book from the picture you provided, and the top
one is mine.  But it's not coming in that form (surprised it's still there)
- there will be a Silverlight 4 version though (if I can write it in time
before Silverlight 5 is announced!).  Unfortunately about 15,000 words (plus
lots of code) of what I had written has now become redundant with the
Silverlight 4 features announced.  I have to admit that really stings - all
that work to be scrapped.

You'll find the .g.cs files under your obj folder in your project...

Re: Blend 3

[Chris Anderson]

Hi Miguel

I'll properly write up the list and send it when I've finished my testing.
Most of the bugs currently centre around the DataPager control - it's got a
few of them.

In regards to the SelectedValue issue, I wrote this up in this article here:

http://www.silverlightshow.net/items/Building-a-Silverlight-Line-Of-Business-Application-Part-5.aspx

under the heading ComboBox Nightmare.  The cascading dropdown height issue
has now been resolved in the Silverlight 3 beta, but there's still no
SelectedValue/SelectedValuePath/SelectedValueBinding properties for
instances where (in my example) you have a Product business object with a
ModelID property, and a collection of key/value pair objects (dictionary
items) of model ID's and descriptions in a combobox.  If you can set the
SelectedValuePath to the ID property on the dictionary items, and you can
set the SelectedValueBinding to the ModelID property on the business
object.  Wires up nicely for business application scenarios in which this
pattern occurs very frequently.  With binding to the SelectedItem property
you have to do an awful hack like I detail in my article using a
ValueConverter.  I've also seen a method of wrapping the ComboBox in a
control and adding the functionality but that's not ideal either.  If
Silverlight is really going for the business application market and
Silverlight 3 appears to be it needs this simple functionality in my
opinion.

I have blogged some of my thoughts on Silverlight 3 here:

Re: Blend 3

[Chris Anderson]

Hi Scott

What's the best way to let you know of bugs and request features - emailing
them here / to you or via Microsoft Connect?  I have a list of 9
bugs/questions/feature requests so far from my play over the weekend.  I've
been writing an article series on the SilverlightShow website since Beta 2
of Silverlight 2 on building business applications in Silverlight and while
this changes everything (I'm very impressed) there are still a couple of
holes left to fill (still no SelectedValue property on ComboBox is a big
one).

Thanks
