The way I tried it was to comment out all of the dictionaries that came after the one in question, and it still doesn't work. Does that mean the problem exists in one of the non-dictionary xaml files?

I wouldn't have thought it was the problem, but it's worth having a look.

It's a damned shame that they didn't increase the buffer since VS1.

Here's a new wrinkle for you - when I do this in the textbox element:

Style="{StaticResource {x:Type TextBox}}"

I get the desired results.

Am I correct in assuming that if this works, then my global style is correct and that there is a problem either in the designer or in WPF?

It would seem logical. Is it something you could send over to me for me to check out? It would be easier for me to diagnose that way.

Silverlight : Dynamic plugins?

Hi there, is anyone familair with or knows if it's possible to create dynamic plugins for a silberlight web project.

For example.

Say you create a silverlight page template showing a banner, menu etc.. and in the middle you have a grid. Now, I've been able to iterate the assembly and create instances of control pages and plop them into the grid, however, I was wondering if it was possible to create control DLL's (based on itnerface) and have them load on demand, as fast as they are dropped into the application BIN folder.

Perhaps even scan a server side bin folder and periodically scan the DLLs.. Any solutions?

thanks

Take a look at Composite WPF and Silverlight[^]

I think this will lead you towards what you are looking for.

Yes. You can use Composite WPF version 2. OR you can also try Microsoft Extension Framework for Silverlight.

I'm having a problem positioning elements and not sure where I'm going wrong. The elements are basically ellipsegeometry paths, since all of the elements are have the same radius.x and radius.y I've added a property Radius that I set when I add them.

This code should position them without an overlap and it works fine as long as the elements have the same radius

Public Sub Group2Elements(ByVal Conductor1 As Conductor, ByVal Conductor2 As Conductor, ByVal Angle As Double)
        Dim DeltaX As Double = System.Math.Cos(Radians(Angle)) * (Conductor1.Radius + Conductor2.Radius)
        Dim DeltaY As Double = System.Math.Sin(Radians(Angle)) * (Conductor1.Radius + Conductor2.Radius)
        Dim Cond2Center As Point = New Point(Conductor2.GetValue(Canvas.LeftProperty) + Conductor2.Radius, Conductor2.GetValue(Canvas.TopProperty) + Conductor2.Radius)
        Conductor1.SetValue(Canvas.LeftProperty, (Cond2Center.X + DeltaX) - Conductor1.Radius)
        Conductor1.SetValue(Canvas.TopProperty, (Cond2Center.Y + DeltaY) - Conductor1.Radius)
    End Sub

and the function to convert Degrees to Radians is as follows

Private Function Radians(ByVal Deg As Double) As Double
            Radians = Deg * System.Math.PI / 180
        End Function

The other problem I'm having is positioning 1 element next to 2 other elements, once again if the elements have the same radius it seems to work.

Public Sub Group3Elements(ByVal Conductor1 As Conductor, ByVal Conductor2 As Conductor, ByVal Conductor3 As Conductor, ByVal Side As Integer)
            Dim DeltaX As Double
            Dim DeltaY As Double
            Dim Angle As Double
            Dim aLength, bLength, cLength As Double
            Dim aAngle, bAngle, cAngle As Double
            aLength = Conductor3.Radius + Conductor1.Radius
            bLength = Conductor2.Radius + Conductor1.Radius
            cLength = Conductor2.Radius + Conductor3.Radius
           aAngle = Degrees(System.Math.Acos((bLength ^ 2 + cLength ^ 2 - aLength ^ 2) / (2 * bLength * cLength)))
           bAngle = Degrees(System.Math.Acos((aLength ^ 2 + cLength ^ 2 - bLength ^ 2) / (2 * aLength * cLength)))
           cAngle = Degrees(System.Math.Acos((aLength ^ 2 + bLength ^ 2 - cLength ^ 2) / (2 * aLength * bLength)))
           If Side = 0 Then
               Angle = AngleBetween(Conductor2, Conductor3) - aAngle
           Else
               Angle = AngleBetween(Conductor2, Conductor3) + aAngle
           End If
           DeltaX = System.Math.Cos(Radians(Angle)) * (Conductor2.Radius + Conductor1.Radius)
           DeltaY = System.Math.Sin(Radians(Angle)) * (Conductor2.Radius + Conductor1.Radius)
           Dim Cond2Center As Point = New Point(Conductor2.GetValue(Canvas.LeftProperty) + Conductor2.Radius, Conductor2.GetValue(Canvas.TopProperty) + Conductor2.Radius)
           Conductor1.SetValue(Canvas.LeftProperty, (Cond2Center.X + DeltaX) - Conductor1.Radius)
           Conductor1.SetValue(Canvas.TopProperty, (Cond2Center.Y + DeltaY) - Conductor1.Radius)
       End Sub

and the AngleBeteween code is as follows

Public Function AngleBetween(ByVal Conductor1 As Conductor, ByVal Conductor2 As Conductor) As Double
        Dim Angle As Double
        Dim Cond1Center As Point = New Point(Conductor1.GetValue(Canvas.LeftProperty) + Conductor1.Radius, Conductor1.GetValue(Canvas.TopProperty) + Conductor1.Radius)
        Dim Cond2Center As Point = New Point(Conductor2.GetValue(Canvas.LeftProperty) + Conductor2.Radius, Conductor2.GetValue(Canvas.TopProperty) + Conductor2.Radius)
        Angle = Degrees(System.Math.Asin((Cond2Center.Y - Cond1Center.Y) / (Conductor2.Radius + Conductor1.Radius)))
        If Cond2Center.X < Cond1Center.X Then Angle = 180 - Angle
        AngleBetween = Angle
    End Function

and finally the the function to convert Degrees to Radians is

Private Function Degrees(ByVal rad As Double) As Double
            Degrees = rad * 180 / System.Math.PI
        End Function

Again both Group2Elements & Group3Elements work if the elements all have the same radius if they don't there's no telling where they will end up.

Any help would be appreciated

Thanks

So, the problem is that if the elements don't have the same radius then it won't work?

Can you send the example project to me so I can take a look and will see whether I can help you to solve the problem or not? My email is mchlsync AT gmail DOT com.

Need help with positioning 3D models in a viewport

Etienne_12320-Jul-09 23:23

20-Jul-09 23:23

We're in the process of creating a 3D modelling application similar to AutoCAD, but with a twist. It is being written specifically for a furniture manufacturer which will use the application to create 3D representations of his furniture. He will also be able to edit the different parts included in a table for example, widening the parts, adding new parts, etc. So far the user can select a piece of furniture from a database, and then 3D models will be created for each part belonging to the specific piece of furniture. Each part has dimensions which is read from the database, but now, these parts need to be added to the viewport in a specific way so that when the entire model is generated, it actually looks like a table (or whatever furniture was selected). At the moment all the parts overlap beacuse they just get added in a fixed position, and we have to use Mousetracking to move the parts around manually.

Anyone have an idea of how the models can be positioned more efficiently without having to move the models around manually with the mouse?

You can have a look at this amazing Sawdust[^] application to get an idea of what we're trying to accomplish.

Pete O'Hanlon20-Jul-09 23:28

The "easiest" way to do this would be to create a composite model, which is a model of all of the parts added together - you would then add this. This is not a trivial task, because you want to maintain a hierarchy of objects, plus the transformations that need to be applied to them to create the final state.

Hi,
I have to add a "Search Box" with a DropDown Button for searching the books.

This dropdown button should have an arrow pointing downwards and the search textbox next to it. so, wen i click on dropdown button, i should get few options (like team, personal, e........) If i select Team then the text "Search in Team" should be displayed in the textbox. A small magnifier for the searchbox will be available too.

I am using C#, XAML..its WPF app

Please help me.
