Hey All,
I was just thinking about this question since it was/is a fairly large topic of discussion on the web this year. Isn't Blend itself a good example of the fact that it is ready ...
Just a thought ...

|
|
|
|
It certainly is ready for LOB apps, and if you want to take a look at the work that Karl is doing, you'll see more examples of WPF and LOB apps. BTW - Visual Studio (future versions) will be more WPF based, with more of the interface being developed in WPF.
|
|
|
|
|
Agreed.
I'm really looking forward to what Karl contributes to the whole thing. VS is a great IDE and more WPF integration can only be a good thing imho.
|
|
|
|
|
Also worth mentioning is the fact that Expression Blend is entirely written in WPF.

I'm pretty sure that was Jammer's point.

 Yep...you're right. That's what happens when one doesn't fully read the original post.

WPF is LOB ready today and this space will only get way better in the future.

For sure ... i'm working on two LOB WPF apps at the moment.

Hi,
I am working with designing custom controls for WPF applications. My problem is I couldn't find a way to force a control property appear in the XAML window by default. It appears only when its changed by the user. for example a button has a propert called myProp which I initializes in the constructor, but It doesn't gets reflected in the XAML file of the window. pls tell me how to force a property to appear in the .xaml file, by default whenever a control is placed on the WPF window.
thanks in advance,
vinod

You can use System.Windows.Browser.HtmlPage.Window.Navigate( Uri ) for similar purpose in Silverlight.

How to assign stream as source to WPF mediaelement control. In Silverlight I can do it using mediaelement.SetSource. I am not able to find out how to do it in WPF application.

Posting in this[^] forum would be more appropriate.

Are you creating your own language service?
If not can you provide a few more details.

Hi Karl,
Yes, I want to create my own language service with Syntax Highlighting and Intellisense. I want to create a usercontrol something like text box. Is this possible?
Thanks,
Charith Jayasundara

Charith,
I'm sorry but writing a Language Service is something I have no knowledge about.
Can I suggest posting your question on the MSDN Visual Studio forum. This will give your question the attention it needs.
If you don't get a reply there in a few days, reply to this message and I'll get you the help. If you need to reply, plesae give me the link to your question on the form.

I'm new to WPF. I'm trying to create an application that displays 3 images stacked on top of one another. The images shall be zoomable and rotateable just like in 3D. I wonder how to achieve this.
What I have done is I have created 3 mesh surfaces stacked on top of one another in 3D using Viewport3D and GeometryModel3D. It's based on a sample program I got from the internet. I haven't figured out how to paint images on the 3 surfaces.
For zooming and rotating, this code uses Transform3DGroup. It's working like a charm.
My final product will have to also have 3D markers scattered on the 3 images and when the user clicks on a marker, some tips shall be displayed. I'm not so concerned about this feature yet as it's a good to have, not must have. I need to get the foundation right first before adding this fancy feature.
Before I continue down this path, I wonder if I'm on the right track.
Any suggestions would be appreciated.
Here's my code:
