Re: Lots of bind/notify classes
Hi Greg,
I hear your pain and reflect it.
You could probably set up a method using PostSharp to automatically create
the necessary setter code, but that's provided you can introduce PostSharp
into your process.
The best I've managed is to set up a Visual Studio code snippet to help
create them quickly. I deferred doing that for a long time, but recently got
around to it and it does make things much less painful. But unfortunately
still far from ideal. Just grab the existing 'prop' code snippet and expand
it out from there. 'tis fairly simple to do and well worth the effort.
ciao, Richard

As you know, you have to keep coding properties like this:
public string CompanyName
{
get {return this.companyNameValue;}
set
{
if (value != this.companyNameValue)
{
this.companyNameValue = value;
NotifyPropertyChanged(CompanyName);
}
}
}
You can create a simple base class to factor out the event, but not much
else, as there is no way I know of to intercept any arbitrary property
setter and add custom processing. Is that right?! Coding the above skeleton
dozens or hundreds of times gets tedious and I’m hoping there’s a better
way. I did consider using a T4 generator to spit out the classes, but that’s
an obtuse way around the problem and will require extra research time (but I
see others have done it already).
I have dozens of existing classes with dozens of properties and I’d like to
use them for binding, but I’d have to expand every property to be like the
same above, which would be hell.

Re: Lots of bind/notify classes
I just saw everyone was alredy talking about PostSharp. Sorry I should read
the thread before replying.
BTW, it doesn't affect Blendability.
I can live with what Steven suggested, of having that extra line bit of code
for each property, but it gets a bit messy when you have derived properties.

RE: Lots of bind/notify classes
Chaps, I have decided that snippets are the quickest way out of this at the moment. It doesn't modularise or reduce the property code, but at least it means I can create them faster. Actually, I forgot how good snippets are. For some reason I neglected them for the last couple of years, now I'm all invigorated about them again and I'm building my own fresh collection.

Re: Images invisible
It may fail for you from home too. I just tried it on my machine and it didn't work. Pinging somesite.com is actually resolving to a real looking IP address. I'm wondering if either someone is now using it for real?! it now resolves to 82.98.86.175. I started to think i had the wrong url but google showed me that somesite.com should resolve to 127.0.0.1. Ah well you can always put it in your local hosts file. Strange that it doesn't work anymore. The main thing is that fiddler needs to be tricked into monitoring local traffic by using your local loopback of 127.0.0.1. It should be an option in fiddler but isn't.

Re: Images invisible (SOLVED)
Yay me :) I think the setting that does that is related to the Use Local IIS Web server. I do the same, tell it to use IIS. I think if you select a Silverlight unit test project it generates a test page and launches that via the file system path by default. It's fine for a unit test but not for your app. Glad you sorted that one out. Nice before a weekend, you can relax a bit now. :) cheers, Stephen p.s. you going to Remix next week? I'll be there.

Why was it using the file system I don’t do that, I prefer to use HTTP as it’s more realistic. I didn’t notice the file system path in the web browser. So sometime over the last couple of days, some configuration of my project has changed, some defaults I dunno what, but by carefully putting all my project settings back according to those of another working SL3 project it has come good. VS has been crashing a lot, and I had to purge all the hidden solution files recently, so that’s probably broken my defaults.

Re: Lots of bind/notify classes
+1 for live templates. I like that it u can use a convention to name
ur fields with the camelcase version of ur prop name.
The other thing consider is using an expression for the
propertychanged method instead of passing a string. That makes
refactoring easier.
RaisePropertyChanged(()=LastName);

I might add, that even if you don’t want to introduce Post# then the
simple base class + Resharper combination is pretty good.
For example, your base class has some methods for raising property
changed events. Then your ViewModel needs a property for first name.
You use the “prop” code snippet, this expands out very quickly to:
public string FirstName { get; set; }
Then ALT+Enter with Resharper lets you convert to backing field in
total 3 keystrokes:
private string _firstName;
public string FirstName
{
get { return _firstName; }
set { _firstName = value; }
}
Then a single call to property changed:
private string _firstName;
public string FirstName
{
get { return _firstName; }
set { _firstName = value; PropertyChanged(FirstName); }
}
Not so bad, very minimal keystrokes.

Re: Long running animation
Greg, You could probably use a simple DoubleAnimation using an EasingFunction.

The path it follows is calculated at start time by mixing random Sin/Cos functions, then the shape will follow the (x,y) coordinates of the function over time. It’s like a moving parametric plot. I’m just not sure what coding technique to use for this effect. I’m guessing I’ll need a frame-based animation, which I’ve never used before. It looks like it “pushes” events to you and you respond and move your elements, but it’s not clear how you control the timing. I just want to run this idea past someone who’s done it before and can confirm if I’m on the right track or not. I’ll keep reading about frame-based animations in the meantime.

RE: Long running animation
Coincidentally, I woke up early this morning and I decided to do some mental health coding. Just for fun I expanded my proof of concept app from last week to animate more elements and have some configuration controls for size, counts and speed. I'm pleased with the great animation effect produced by a relatively small amount of core code. Imagine how far you could take this and create some really mind-boggling animations with perspective 3D, shading and complex shapes. http://www.orthogonal.com.au/computers/hypno/index.htm Cheers, Greg ___ ozsilverlight mailing list ozsilverlight@ozsilverlight.com http://prdlxvm0001.codify.net/mailman/listinfo/ozsilverlight
