and to draw this object i must to add it to Viewport3D.Children which is Visual3DCollection
when i add the object to that collection then remove it it throw a 'NullReferenceException'
the exception was thrown by a method inside the class which is UpdateTransform() in OnRendering eventHandler
cold someone help in this ?
and the other problem that i can not replace ScreenSpaceLines3D with
any thing i must use it
Sample of what happens :
<pre>
Viewport3D viewport;
ScreenSpaceLines3D screenSpaceLines3D;
public void AddLine()
{
screenSpaceLines3D = new ScreenSpaceLines3D();
screenSpaceLines3D.Color = Colors.Blue;
screenSpaceLines3D.Points.Add(new Point3D(0, 0, 0));
screenSpaceLines3D.Points.Add(new Point3D(10, 10, 10));
screenSpaceLines3D.Thickness = 1;
viewport = new Viewport3D();
viewport.Children.Add(screenSpaceLines3D);
}
public void RemoveLine()
{
if (screenSpaceLines3D != null)
{
viewport.Children.Remove(screenSpaceLines3D);
}
}// The exception appears her
</pre>

is it possible to add transparency to an ModelUIElement3D
ive made a cube and a pie but want to make them transparent..
|
|

Sure - just apply a transparent brush. Brushes provide an alpha component just for this type of case.

Don't know about books, but there's lots of info here:
.NET Framework 3.5[^]
All this same info is in the local help in Visual Studio as well.

Hello Friend,
For WPF you can see following book.
Windows Presentation Foundation Unleashed, SAMS publications, Author : Adam Nathan
For WWF, Version 4.0 is totally different than version 3.5 . We can say that Microsoft has changed WF totally in 4.0 . And currently no book is available for 4.0 . But you can get Beta2 of WF 4.0 and samples from Microsoft side.

Hi,
I am working on a WPF application. I want to place table with some lable controls in my form to display data. For this I tried the folowing code.
<FlowDocumentReader Margin="131,133.738,184,217.262" ScrollViewer.HorizontalScrollBarVisibility="Hidden" >
<FlowDocument >
<Table CellSpacing="3" >
<Table.Columns>
<TableColumn Width="80" />
</Table.Columns>
<TableRowGroup>
<!-- Header row for the table. -->
<TableRow Background="Orange">
<TableCell>
<TextBox x:Name="txtTransmiterFee" Width="80" LostFocus="txtTaxPreperationFee_LostFocus"></TextBox>
</TableCell>
</TableRow>
</TableRowGroup>
</Table>
</FlowDocument>
Here I am getting some extra features for zooming, scrollbar etc, but I want just a table.
If any one have any idea to place a table control in WPF or amy modifications in this code to display just like a table, please reply me.
Thanks in advance.

Maybe you can use a simpler flow document reader like a
FlowDocumentScrollViewer:
<!--<FlowDocumentReader Margin="131,133.738,184,217.262" ScrollViewer.HorizontalScrollBarVisibility="Hidden" >-->
<FlowDocumentScrollViewer IsToolBarVisible="False" Margin="131,133.738,184,217.262" HorizontalScrollBarVisibility="Hidden" >

Hi Mark Salsbery,
Thanks for your reply. It helped me and now I am getting table without unnecessary features.
But now the width of the table is fixed and I am unable to increase the width of the tableto the width of the form.
Please reply me if you have any idea to solve this
Thanks in advance.

Wrap the FlowDocumentScrollViewer in an element that resizes its children,
like a Grid or a Window.
For example (borrowing the flowdocument from the documentation), note how resizing this window resizes the table to fit:
<Window x:Class="WPFTester.Window4"

Ok, I have a Silverlight application and I am trying to receive message events from a stand alone Windows Workflow (state machine). Now I am pretry sure that this can be done using a duplex service. However, the issue is not with the service that will live on the WF side, but with our service that is going to live in Silverlight app. We are trying to develop a service that will complete a "handshake" with the workflow in order to tell the flow what activity messages we want and then have our silverlight app listen for those specific messages and then receive those messages. If anyone can help that would be great. Also I do understand that Silverlight does not support Windows Workflow. These two applications will run independently of eachother. This will be a Live message update scenario.
Thanks, I hope someone can help!!

Hi all,
I used to use .Net application for all our web application. I did not really interested to do silverlight buiness application dispite it is very cool and the UI is nice.
i had an argument with one of my collegue. he is saying that we can use silverlight Biz. application instead of our web application for our development. but what i am saying that silverlight is not much sopheticated to be able to develop huge application. it is designed for small and basic applications only.
this was our agrument. i tried to find out comparision between silverlight Business Application and Web Application. i could not find.
thats why i am posting my question here which is:
Can we use SilverLight Business Application to do all our web applications

Maybe an understanding of what Silverlight is would help
to start with...
What is Silverlight?[^]
What do you mean by "web application"?
What is "SilverLight Business Application"? Do you mean the
project template that comes with the Silverlight 3.0 development
tools?
Silverlight is implemented as a browser plugin (like Flash) so Silverlight
applications run on the client side. Silverlight can be hosted on any web page
including web pages from ASP.NET web applications.

hi,
i know what is silverlight and i know it is a browser client application in web page. but in silver light also you can create business application that can be communicated with the database through domainDataSource class and you have alot of controls like DataGrid FormView etc.
what i am asking is that; is it posible to develope a complete business application like what we do in .net web application.
i think the best thing for me is to take an existing web application and try to re-develop it using silverlight business application.

Is it possible? Yes. I'm doing it. But your definition of a
"complete business application" may be different.
Again, the big difference is, Silverlight runs .NET on the client,
where any other .NET web application runs on the server. You can take
advantage of code running on the client to provide a richer UI.
I prefer to use Silverlight as part of a .NET web application, so I can
leverage >NET code on both the client and the server.

Hi,
I am using WPF table in my application to display my data.But the table was fixed to particular width. I am not able to change this. I want this table's width as my WPF form width. I tried in <FlowDocument.Resources>, Style tag. But not able to change the width and height. Below is my code.
<FlowDocumentReader Margin="67,150,51,267" >
<FlowDocument>
<FlowDocument.Resources>
<Style TargetType="{x:Type Paragraph}">
<!--<Setter Property="" Value="100%"/>-->
<Setter Property="FontSize" Value="12px"/>
</Style>
</FlowDocument.Resources>
<Table CellSpacing="3" >
<Table.Columns>
<TableColumn />
<TableColumn />
<TableColumn/>
</Table.Columns>
<TableRowGroup>
<!-- Header row for the table. -->

<TableCell >
<Paragraph FontSize="12pt" FontWeight="Bold" >Description</Paragraph>

FYI, I (and many others) do not even look at code if it is poorly formatted (no tabs) and isn't syntax highlighted. Here is an example of well formatted and syntax highlighted code:
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Button Grid.Column="0" MaxWidth="100">Overwrite</Button>
<Button Grid.Column="1" MaxWidth="100">Skip</Button>
<Button Grid.Column="2" MaxWidth="100">Cancel</Button>
</Grid>
And here's what was typed to get the above to look the way it does:
<pre lang="xml"><Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Button Grid.Column="0" MaxWidth="100">Overwrite</Button>
<Button Grid.Column="1" MaxWidth="100">Skip</Button>
<Button Grid.Column="2" MaxWidth="100">Cancel</Button>
</Grid></pre>
Basically, you just surround your code with PRE tags and make sure to specify the correct language (in my example, the language was XML) by setting the "lang" attribute to the appropriate value. I got all the ampersands, less than signs, and greater than signs to encode properly by clicking "Encode HTML tags when pasting", which is a checkbox just below the textbox you type messages into. By the way, my above code sample has nothing to do with your question... it's just a demonstration of what is expected from people who ask questions. FYI, you can edit your original post to improve it if you want; you'll be much more likely to get a response that way.
Visual Studio is an excellent GUIIDE.
|
|
|
|
|
Whoops, you got your tags encoded!
|
|
|
|
|
That was my intention. The first PRE block shows what syntax highlighting is and the second shows how to syntax highlight (by using PRE blocks).
Visual Studio is an excellent GUIIDE.
|
|
|
|
|
Interesting, I don't recall having this happen when I've used the <pre> tags in the past. My apologies, I have obviously missed an experience, or maybe my brain hasn't kicked in properly this morning.
