What form will his project come in ? Why can't you just inject his XAML into your project, verbatim ?
Yes, having him create user controls seems like a good way for you to reuse them.

Hello.
His project is a standard WPF app, a single XAML with code behind and an extra class to handle some more complex math.
He's created his app at a specific size, my app has a 'hole' in it the same size, currently filled by a canvas. I was wondering if I could load his XAML into the canvas?
Regards, E.

hi
I want to download file from the server. For this purpose i created a web service which returns a byte array of file. On silverlight page.xaml i got the byte array but how can i convert it to file so that i can save file to client hard disk.
If there is any other way to download file from server plz tell me.
Thanks in advance.

In Silverlight 2, the only access you have to the user's local hard disk
is using Isolated Storage:
Silverlight Isolated Storage[^]
Silverlight 3, now in beta, provides a save-file dialog that will allow the user
to select a place you can save the file to. Note that this will still require user
interaction - you won't be able to just write anywhere you want to.

You can do it using a trick.
Instead of calling the web service, from Silverlight call javascript method that will make an open to a given URL, this URL will point to a custom HTTP handler, then you return your file (implementing a custom HTTP handler it's easy can send you some info or link), you only has to say that the file is an attachment.
In my case I just render e jpeg, js:
function showReportDiagramPopup() {
//http: //www.javascripter.net/faq/openinga.htm
window.open("DiagramRenderPopup.aspx", "DatabaseDiagram", "scrollbars=yes, width=800,height=600", false);
// NOT IN USE, rather using popup
// Finally we are not going to use a popup, we just open the generated image as an attachment
//window.location = "DiagramImageHandler.ashx"
}
In Silverlight:
public void ShowDiagramImageRenderPopup()
{
System.Windows.Browser.HtmlPage.Window.CreateInstance("showReportDiagramPopup");
}

It seems that RoutedEvent is quite similar with event. Is it true that we can do anything by event instead of RoutedEvent? If it is true, what is the advantage of RoutedEvent?

Which "event" are you referring to ?
Routed events are very powerful UI events. They are flexible enough to be placed at any place in the Element tree and handled by any other element. You can have a set of buttons and all the clicks handled at a common root. Also, there are scenarios like EventTriggers in XAML which only work with Routed events.
More information here[^]

Well, let me explain myself a little bit clear. On msdn there is a example like this.
<br />
public class MyButtonSimple: Button<br />
{<br />
public static readonly RoutedEvent TapEvent = EventManager.RegisterRoutedEvent(<br />
"Tap", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(MyButtonSimple));<br />
<br />
public event RoutedEventHandler Tap<br />
{<br />
add { AddHandler(TapEvent, value); } <br />
remove { RemoveHandler(TapEvent, value); }<br />
}<br />
<br />
void RaiseTapEvent()<br />
{<br />
RoutedEventArgs newEventArgs = new RoutedEventArgs(MyButtonSimple.TapEvent);<br />
RaiseEvent(newEventArgs);<br />
}<br />
protected override void OnClick()<br />
{<br />
RaiseTapEvent();<br />
}<br />
<br />
}<br />
<br />
<br />
But, from my point of view, I could although done it this way
<br />
public delegate void DelegateClickEventHandler();<br />
public event DelegateClickEventHandler DelegateClickEvent;<br />
<br />
protected ovveride void OnClick()<br />
{<br />
if(DelegateClickEvent!=null)<br />
{<br />
DelegateClickEvent();<br />
}<br />
}<br />
And I could use this event in XAML either. So i am a little confused.

Routed events, cunningly enough, are designed to support event routing. Basically this mechanism allows you to register an event inside one element but, and this is the clever part, it can be raised by a completely different element. A simple example (and commonly quoted) is that a toolbar button click can go through the toolbar, then maybe a toolbar container, before finally being handled by your code. As you can see, this goes way beyond what you can manage with a simple event because the event would not bubble up in a traditional event scenario.
The problem you have here, is that the example on MSDN isn't terribly well explained, and the concept isn't clearly defined on the MSDN either.

That was nicely explained  That example on MSDN is pathetic and is more misleading than helping. When you read the explanation you somewhat get the picture but when you reach the example, it totally leaves you guessing into the behavior as of a normal event.

Isn't it just? I really wish they'd up the quality of samples on MSDN. I used to rely heavily on MSDN - now, I tend to ignore it.

It doesn't matter anymore. My MSDN is Josh, Sacha, Karl, Dr.WPF and Pete[^] The WPF disciples are fabulous!

Thanks - it's an honour to be among such giants, and the Disciples are as fine a bunch as you'll ever meet.

Pete gave a nice explanation. Just to highlight, the Tap event of your example could be handled by any other UI element in the Element tree instead of your Element. Also, could be used as an EventTrigger to start an animations when the event is fired. You can derive the analogy on similar lines as a CLR property and a Dependency Property.

Now I'm much more clear. As you said, I was totally confused by the example in MSDN. It appears that MSDN just offer a example which can be perfectly debug, but you can not learn the characteristic. Well, Especially in China, little company is using WPF. And you could not find many resources about WPF. Anyway, specail thanks for ABitSmart and Pete.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Hi everybody,
We are using Composite WPF for our new project, and I'm looking for UI process library for it. For WinForm applications, there is UIPAB, while for WPF, I can't find anything like that. I looked into the Workflow Foundation, but it lacks the features in UIPAB. Any suggestions for UI process design and development for Composite WPF?
Thanks,
Jie

I do not see any reply.But as far as i know we can customize the UIP App block for WPF.

Hi,
I was really happy to see the NearestNeighbor rendering added in SP1. I thought this would solve the blurry images and such, but what I see is that it's rendering my images incorrectly. It seems to omit rows or pixels if the image is at certain locations. This is easily reproducible by aligning an image to the center of the window, and slowly resizing the window.
I don't think this is supposed to happen with NearestNeighbor rendering since the image has the same resolution as my display.
Here is Sparpness.PNG from the Microsoft PixelsSnapping tutorial for example:
http://img5.imageshack.us/img5/4061/sharpnessfail.png[^]
Is there any way to make this work?
|
|
|
|
|
I'm curious...
What if you try four side-by-side renders (similar to the
code at Pixel Snapping in WPF Applications[^])...
1) SnapsToDevicePixels=False, RenderOptions.BitmapScalingMode=Unspecified
2) SnapsToDevicePixels=True, RenderOptions.BitmapScalingMode=Unspecified
3) SnapsToDevicePixels=False, RenderOptions.BitmapScalingMode=NearestNeighbor
4) SnapsToDevicePixels=True, RenderOptions.BitmapScalingMode=NearestNeighbor
Do any of those combinations render the way you'd like?

None of them is correct. Looks like snapstodevicepoxels has no effect in images at all.
NearestNeighbor always, and it's always blurry without nearestneighbor.
