Re: HTML vs Silverlight - comparative effort?

[David Burela]

My general rule of thumb is:
*Public facing* - technology choice defaults to ASP.Net MVC
*Internal Line of Business app* - depends on how interactive you want it to
be. I usually default to Silverlight because of the ease of doing
animations, visual bling, etc.

If you're doing a corporate app and you control the clients - then you have
the luxury of choosing whichever platform is going to deliver the best app
experience.

Hi David,

Good point, I didn't mention the target market. We're doing a corporate app. 
It'll be deployed on a server within the companies. We're only expecting PC & 
possible Mac clients.

Cheers.

Yeh it's sad that plugins like SL and Flash have these issues since
alternatives need to be cross browser compatible which is still very
annoying.

I have started to develop a new web based application (shameless plug
www.youreontime.com) in Silverlight. But shortly after starting I redid it
all as a HTML web application. I am sure glad I did now. Many of our
potential customers started buying iPads to use the app on and with
Silverlight we would have been dead in the water. With a web app it works
really nicely on the iPad needing just a few tweaks to make the UI a bit
more finger aware.

HTML vs Silverlight - comparative effort?

[James Chapman-Smith]

Hi folks,

I got asked a question today that I don't really have the experience to answer 
and was hoping someone here could help.

If I'm going to develop a new "web-based" application in HTML or Silverlight, 
what would the comparative effort be like? And really, what kind of pros & cons 
are worth evaluating?

By HTML I am thinking ASP.NET MVC, but it could be something else ".NET"-ish.

Cheers.

James.

Re: Propagate Database changes to application

[Grant Molloy]

Thanks everyone for feedback..

Joseph,
SQL Server, yes, version either 2008 or 2008 R2.. More than likely R2, but
not nailed down yet.
Client type is a DAL DLL.. I want the DAL to know when the data changes, and
the client will subscribe to DAL events, and then DAL can fire off event
when data is changed, and App can decide what to do about it.  Kind of like
a publisher / subscriber model implementation.

I'm not 100% sure I'm going about it the right way or have the events in the
right place (ie in the DAL)..

RE: [OT] SQL Server Windows Authentication

[Greg Keogh]

Sorry folks, I emailed Greg L (too many Greg's?!) a few days ago to tell him
I found a solution to my problem where I can't connect with Windows
Authentication.

Greg W's suggestion is almost what I did: I created a domain Group called
'SQL Administrators', put myself in it and then added that group to Instance
> Security > Logins and gave it the sysadmin role.

I thought I'd have to tick all of the User Mappings or add the group to each
database, but that wasn't necessary. Simply creating the sysadmin Login gave
me implicit control over all databases. I'm not sure why I didn't have any
problems on my old domain, but it's destroyed and I can't look back to see
why.

Let us know how it goes.

 

I can't see any managed code library to use Redis. It says it's scalable,
but then it says it stores everything in memory. It claims to be basically a
key-value store (I use Managed Esent PersistentDictionary class for that)).
I would also be curious to hear if anyone has used it and thinks it has
anything to offer over the other more famous and popular non-big-name DBs
like Raven, SQLLite, etc.

Re: Propagate Database changes to application

What type of client is it? Do you control the means by which data is written
to the table? Are clients deployed to the internet or intranet? What kind of
database are we talking about here (I assume you mean SQL Server, since you
mention SqlDependency) but which version?

I presume SQL Server 2008, so a data driven subscription is probably

You will see that MS dropped Notification Services, as no one used it.

Tracking PostBack in a usercontrol?

[Anthony]

Anyone have a technique they use to detect IsPostback on a asp.net custom
user control?   You suggestion would be appreciated..i have searched the net
and seen many techniques.but I know some are incorrect.

 

 

Eg  You cannot use page.ispostback in a user control!

Re: EF gurus

[Stephen Price]

Well.

Looks like I've narrowed it down to a workaround. Firstly, the issue has
nothing to do with EF. Embarrassingly, it was client side, and I totally
blame my learning two technologies simultaneously, in combination with the
irresponsible usage of the word/classname 'Entity' by RIA Services, for my
confusion. ;)

The problem seems to be when using [Composition] with RIA Services with the
RadGridView. When I press escape to undo the creation of a new row, it
throws the exception I've been getting when it tries to remove the entity
from the SourceSet. The problem was not happening where composition was not
being used. I made some changes to remove the usage of composition on this
particular page and now pressing escape to undo a new row insert works.
I've cross posted this to the OzSilverlight in case someone there is
interested. Surely I can't be the only person to want to undo an insert on a
composition service call?
Also, a search for this error in combination with RIA Services, rather than
EF actually turned up this post ->
http://forums.silverlight.net/forums/p/215248/511408.aspx
Amazing what you get when you actually search for the right thing, hey?
*blush*

As temped I was to not post this, someone else might actualy benefit so meh,
I'll take it as a learning exercise.

cheers,
Stephen

p.s. I'm just happy to be here.
