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.

Hi,
I am new to Silverlight Applications. I created one media player control to play video in asp.net website.I want to drag and drop that media player control to desired place when we run the application but there are no events to drag and drop the video. I tried media element control its working fine for drag and drop functionality but i want that feature in media player control. Is there any other alternatives to drag and drop videos to desired place when we execute the application.
Thanks in Advance

Isn't the MediaPlayer an ASP.NET control?

I used Media Player control in Asp.Net but i am not getting how to Drag and Drop Video to desired location using that media Player control.

Maybe try posting on the ASP.NET board since it's not a silverlight control.

ok. thank you i posted it in asp.net,dotnet spider,c# corner forums but i didn't get any reply from those forums. And I tried in another way. I added new silverlight project in sasp.net website and I created media element control in xaml file for drag and drop functionlaity and I used that .XAP file in my aspx page when i run in my local system that page running and i am trying to host it in my iis server and there is no silverlight when i open that link it is showing blank space in place of that xaml content. If you know the reason please suggest me how to host my application in server.

Make sure the xap is getting published to your site folder.
Also make sure the appropriate MIME types are configured in IIS:

Sir,
i have visual studio 2005. Should i jump to 2008 version to work with wpf..

I would highly recommend it. You'll get much better designer support
and the .NET 3.5 framework!

I would suggest to even upgrade to .Net 3.5 SP 1 and take advantage of the performance improvements to WPF and goodies like LINQ, Extension methods etc.

Yes... You need to install VS 2008 because VS 2005 does not support WPF...

OK, I've asked this 6 times on the MSDN forums (they have a lot more WPF traffic ) and got not one reply. So, CPians, here's your chance to shine.
Why does the MediaElement suck ? Am I doing something wrong, because I can't get even a smallish video to play smoothly with sound. Are there settings that improve the performance, because what I get with the default is a joke. I created a simple form with a MediaElement and a button, and got the button to choose a file to play, and even then, the result is choppy ( the video freezes from time to time, the sound is fine ).

Christian - it's possible that it's trying to perform software rendering. Try using the WPF profiler to see if that's what's happening here[^]. You might also want to look at hosting the Media Player as an ActiveX control (not an attractive option, but it may be the way to go).

Hi Pete.
It's been tested on several PCs, so I assume if it's rendering in software, that either there's nothing I can do about it, or that there's something specific I am doing which I could change to make it render in hardware. Which is it ? Can I do anything to make it render in hardware across all machines ? All my machines have excellent video cards ( at least I thought ). They are all XP SP2.
I've actually got it working with the WMP control from C#, but that's created all sorts of issues, the control doesn't like it when I ask it to play a new video after the last one ends, I need to create a timer that asks over and over until it works, and there's all sorts of general rendering glitches, as well as complexity because I need to hide the control before I do any sort of animation. Basically, my app looks like crap now, compared to how it would look if I could render video using WPF.
I will attempt the profiler on my basic app, but I'd appreciate your advice on what I can do about it, if it's rendering in software.

Do I need to download the full Windows Platform SDK to get the performance testing tools ?
It's OK, I found a seperate download.

Christian,
What format is the media?
Is it getting rescaled during rendering or are you showing it in native size?
Do the results differ if you set the MediaElement's source at runtime or not?
For example, does a simple implementation like:
<MediaElement Source="FILE://E:/Source/Media/Step_into_Liquid_720.wmv" Width="640" Height="480" />
play better than what you're doing?
I get great results with WMV files (icluding HD), both local and streamed, and both on WPF and Silverlight (Mac too!),
and Silverlight doesn't have hardware rendering help. For example, the file
used in the code above is an HD sample - Video: 6500kbps 1280x720 24fps Audio: 384kbps

Rescaled. We want to play the video within our full screen UI, so size will depend on screen res. I'd have expected that to be a common need.
Mark Salsbery wrote: play better than what you're doing?
That's only marginally simpler than my test app. My test app sets the source in code. I definitely can't be hard coding the source, but could that make a difference ?

I'm just trying to narrow down why you're getting poor performance.
I wouldn't expect lack of hardware rendering on a modern PC to matter much -
it will use more CPU and RAM maybe but it still should play smooth, unless you have
a real low-budget video adapter.
The part I distrust most is setting the source at runtime. The first time
the source is set should be fine, but setting a new source over an old one,
even though it "should" work, may be a problem.
So if you hardwire the source like I showed, just for testing purposes, is the
performance still crappy?

Common need, yes, but have you tried it at native resolution, just to see?
