Is there a single method in WPF that can handle all types of input at once, like WndProc in Windows Forms? Or do I have to capture and forward each event separately?

Thanks for your reply.

Of course, it should do the job. Anyway, it seems to be a pretty strange work-around. You're provided with dozens of overridable methods for handling input, but you have to use native hooks...

That's the way the ScrollViewer is designed to work.
The ScrollViewer uses a fixed-size viewport to view a
portion of the scrollable content.

Data class implementations not fully passed to Silverlight?

Michael Eber28-Dec-09 11:56

Michael Eber

28-Dec-09 11:56

Here is my scenario:
Data Layer : running as an simple web service as required by Silverlight
Entities are generated from the database tables
An extended class is defined with the following additions:

public partial class CustomerMaster
{
    public override string ToString( )
    {
        return this.CustomerName;
    }
}
public partial class CustomerLocation
{
    public override string ToString( )
    {
        return this._LocationID;
    }
}

CustomerMaster and CustomerLocation are two entities derived from the database.

Silverlight side

When I get my data I bind a list box to the result of my async query.

I get the list of customers no problem.
But listbox calls ToString() on my objects and I'm getting the default behaviour (namespace) not my overridden code!!!???

Anyone know a reason why this would happen?

Methods are not part of the DataContract so they won't be available when you create the proxy for the client.

Hmm, well Do you want to draw a room or a grid?

3D WPF drawing is not really lines.

Here is a simple cube mesh:

// Define 3D mesh object
MeshGeometry3D mesh = new MeshGeometry3D();
// Front face
mesh.Positions.Add(new Point3D(-0.5, -0.5, 1));
mesh.Positions.Add(new Point3D(0.5, -0.5, 1));
mesh.Positions.Add(new Point3D(0.5, 0.5, 1));
mesh.Positions.Add(new Point3D(-0.5, 0.5, 1));
// Back face
mesh.Positions.Add(new Point3D(-1, -1, -1));
mesh.Positions.Add(new Point3D(1, -1, -1));
mesh.Positions.Add(new Point3D(1, 1, -1));
mesh.Positions.Add(new Point3D(-1, 1, -1)); 

mesh.TriangleIndices.Add(0);
mesh.TriangleIndices.Add(1);
mesh.TriangleIndices.Add(2);
mesh.TriangleIndices.Add(2);
mesh.TriangleIndices.Add(3);
mesh.TriangleIndices.Add(0);
// Back face
mesh.TriangleIndices.Add(6);
mesh.TriangleIndices.Add(5);
mesh.TriangleIndices.Add(4);
mesh.TriangleIndices.Add(4);
mesh.TriangleIndices.Add(7);
mesh.TriangleIndices.Add(6);
// Right face
mesh.TriangleIndices.Add(1);
mesh.TriangleIndices.Add(5);
mesh.TriangleIndices.Add(2);
mesh.TriangleIndices.Add(5);
mesh.TriangleIndices.Add(6);
mesh.TriangleIndices.Add(2);

Hi friends.
Can we change ColumnDefinitions via a StoryBoard in WPF?
e.g : I wanna change the following ColumnDefinitions

<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Height="0*"/>
</Grid.ColumnDefinitions>

to this one :

<Grid.ColumnDefinitions>
<ColumnDefinition Height="0.585*"/>
<ColumnDefinition Height="0.415*"/>
</Grid.ColumnDefinitions>

Thanks in advance.

WPF AutoIT/Flash question

Hi, i was wondering is it possible to integrate autoit into an wpf application? Also is it possible for C#/WPF to get dynamic data displayed on a flash application? Example: a flash game, be able to get the current score you have and display it on the wpf application. The flash game is made by a 3rd party so I dont have source or resources to it. Thanks.

This is really an intreop question.

I have no idea what AutoIt is.

As for Flash to WPF.

Hmm, My question is how do you put FLAH into a WPF application. I think what you are really asking is how to interop between Flash and Silverlight. You can host WPF in a browser but it is not safe for normal use over the internet etc.

Well, I'm not sure on the Flash side but Silverlight can script to HTML DOM. That is how I would do it. Short of that, you would have to write a plug-in for both applications and have the server host some sort of COM between the two. In this case it wouldn't matter what you used. However you don't have the source. So that's not an option.

The Webbrowser in WPF can't display page unless mouse moving on.

This bug can't reproduce in my demo project, and I don't know how to fix it. I tried:

call WindowsFormsHost.UpdateLayout. (Failed)
call WindowsFormsHost's child, a WebBrowser control. call WebBrowser.Update or WebBrowser.Refresh. (Failed)
call WindowsFormsHost.InvalidateVisual() (Failed)
Is there other solution?

I even simulated mouse moving on like this:

AutomationElement element = AutomationElement.FromHandle(winAdHoster.Handle);
ATGTestInput.Input.MoveToAndClick(element);

this failed again.

Glad to discuss with you and best wishes.

Where do you see Silverlight a few years from now?

Hello. My company is looking into beginning to integrate Silverlight into some of our upcoming web projects soon, but before we do, I want to get some opinions from those who are already experienced in developing in it.

From what I've read, Silverlight seems to be slowly picking up marketshare (the stats I read showed it's now installed in 40% of all users computers), which is a good thing...but what do you see for the future of Silverlight? Is it here to stay or would you consider its future unknown at this point?

Have your users voiced reluctance to install Silverlight or have you seen an uptick in customer service calls/emails because they couldn't or didn't want to install Silverlight to view your web pages?

Just trying to weigh our options at this point before we dive into it.

Thanks.

Hard to say, this early in the game (Ok, it's not THAT early)... But here are my predictions:

1) Adoption will continue to be slow for a while, because let's face it... Most people don't even know what Silverlight is, and Microsoft isn't using their marketing machine yet (Probably waiting until version 4 to start pushing it).

2) Microsoft will package SilverLight in with the next Windows 7 service pack and all subsequent OS versions. Adobe will raise the old monopoly issue (Using one monopoly to gain another), but MS will just claim it's part of the .NET/WPF framework.

3) Flash will hang on for a long time as a game development platform and for "rich content" websites (Pretty menus, etc), but Silverlight will take over for more serious web applications, particularly e-commerce.

Disclaimer: These are just my personal predictions, not established facts, so agree or disagree at your own risk.

There's no guarantees in any platform one chooses to develop for,
but I do know Silverlight is actively and rapidly being developed
and there's no indication that is going to cease. New versions are
being released at an unprecedented rate. New controls are released
early via the toolkit so they get well tested/fixed in live environments
before being rolled into the Silverlight runtime.

I find the whole "market share" thing kind of goofy...
The end-user part of Silverlight is free so IMO doesn't have a
"market share" of anything. It has an installed base perhaps.
End users aren't going to install Silverlight unless they go to
websites that require Silverlight. Publish the websites and they
will install Silverlight. As more sites use Silverlight, the
installed base will grow.

My end users are doctors - not all of whom are computer savvy.
I was a bit worried at first about whether they would install
Silverlight. I chose to not specifically mention it and just see what
happens. I customized the "Must Install Silverlight" HTML adding
an email link users could use if they had any questions, concerns,
or problems. Happily, I have received exactly ONE contact this year,
and that was just someone in a locked down environment that needed to
have one of their IT people allow the install - the IT person installed
it without hesitation.

In summary, I love it, and my users love it. There's zero application
deployment issues for the end-user, it runs on Macs, and I get to use
familiar development languages/tools to provide all that.

I am a Microsoft developer, have been for over ten years. When I first heard about Silverlight I was excited as it offered me the opportunity to utilize RIA (rich internet applications) while utilizing the XAML markup and .Net framework language. It short, it allowed me to mimic a Flash website/component, and then, surpass it using .Net for major database and other high-level code/interactive programming.

However, here is the glitch. I have been unsuccessful in getting Silverlight to install on IE (works fine on Firefox). Now, if I, as a seasoned programmer cannot get Silverlight to install properly on IE, despite all attempts and researching how to fix, then surely I am not alone, and this glitch could harm any project I deliver in Silverlight.

Programming is moving into RIA with a roar, and that is the future. Windows forms is being "replaced" with Windows Presentation Foundation, a very powerful format that delivers AWESOME PC-level programs. Silverlight is the "sister" of WPF in that it is the Web counterpart of WPF (albeit with a few less features).

I do not think MS is promoting Silverlight well, and true to form, I believe MS is releasing Silverlight, warts and all, just to get it out. As of this writing Silverlight 4 is do out soon. MS has followed an unprecedented rapid upgrades of a programs versions in Silverlight as has never been seen before (Silverlight 1 came out in late 2007).

While I can tell you with absolute certainty that the Internet will migrate out of the standard HTML format into a more robust RIA format, such as XAML, I worry Silverilght will always be the bastard child in that new venue with Adobe Flash & Adobe Air (like MS WPF) being the preeminent tools.

This does not please me as the last thing I want to do is learn ActionScript. ActionScript is a toy compared to the .Net Framework. If by mid-2010, MS does not clean up its act with a flawless Silverlight install on the browser, and additionally, if the Silverlight.net website does not pursue a more advanced approach to teaching developers on how to program in Silverlight (they provide just stupid toys & snippets), I would not recommend developing a site in Silverlight. The fact that NBC Sports & MLB.com both in a span of less than 6 months dropped the Silverlight technology and switched to Flash is a telling sign.

So in short, the future of the Net? Definetly RIA. As to whether Silverlight or Flash, I think the jury will be returning a decision real soon and Microsoft & Silverlight.net, because of their ineptitude ( ie. I mean, come on, MS has billions to play with), will not like the decision. Do NOT rush into developing a Silverlight website at this time: Since Microsoft has shown no real commitment to throw GOOD money & utilitize compentent management to the success of Silverlight (Scott Gunthrie is the MS VP in charge of Silverlight) I would not deploy one line of Silverlight code to your website.
