Did you try starting with a PNG of the character, at a decent size, and see if it will convert it to XAML for you ?

What you could do is run bitmap representations of your fonts through Vector Magic[^] and use the resultant vectors.

Thanks for your reply.

Oh I wouldn't need any of that. I run TrueType fonts [^], so I seek for a vector-to-vector conversion

The problem is that there are tons of various vector-to-vector format converters and only one (mentioned by Christian) which can do {(whatever)=>(WPF shape)} conversion, which is very commercial.

Fair enough, but you might want to see what Inkscape[^] could do for you. It converts to XAML internally, and is a vector based editing tool like Illustrator.

[EDIT]
I've just converted a piece of text in it into a Path with no problem. It's pretty easy.

Hi All,

I am new to silverlight. I am creating a silverlight page of 1200 width and 2000 height dimensions. When the page is displayed the vertical or the horizontal scrollbars are getting displayed and hence the page appears cut. Please help me out to solve this issue or provide appropriate pointers.

Thanks in advance for your time.

Re: Vertical/Horizontal scrollbar for silverlight page

22-Jun-09 19:52

Hi Mark,

I want the silverlight web page to have scrolling capability. At present when i build and test the solution, the web browser doesn't display the contents completely as the contents are extending beyond the web browser window. I am not able to scroll it either horizontally nor vertically to see the full page contents because silverlight is not showing any (auto)scrollbars.

How could this problem be overcome?
NOTE: My silverlight canvas height is 1200 and width is 1500. Hence the web browser doesn't display the contents completely.

Thanks.

Sunil

I am running some threads so that data initially gets loaded partially and then with the threads, the should get loaded at runtime.

But if I close the browser and the thread is not get completed at a certain point then it throws following error:

Re: Catastrophic failure while running thread with BackgroundWorker

22-Jun-09 3:14

I have one button added each time when the thread gets completed for each time.
It means if it brings one chunk of data in one thread then one button added, then it brings another chunk then another button added, brings third chunk third button added, brings fourth chunk fourth button added and so on.....

But in between if we close the browser then exception occurs at the constructor of button control

I dont understand you problem clearly but,
It seem to me that you have problem when your application close.
Make sure you close all your thread at application close event.

ListBox Binding From Within A User Control

22-Jun-09 21:16

I got a link http://msdn.microsoft.com/en-us/library/system.componentmodel.backgroundworker.cancellationpending%28VS.95%29.aspx[^]

I have written

if ((worker.CancellationPending == true))
        {
            e.Cancel = true;

        }

in bw_DoWork(object sender, DoWorkEventArgs e)
but still getting the same exception.

I think this is because bw_DoWork not getting that the browser is getting closed.

How can I tell it that? Do I have some flag so that it is conveyed to this event that browser is getting closed?

Good people,

I have a listbox embedded within a user control.   The user control is then housed within a data template.   I have created a dependency property for the user control; the type of this property is an observable collection that is intended to be the source of items for the listbox.

The difficulty I am having is that the listbox will not display the items when the user control is part of the datatemplate.   It will display items when it is not part of the data template.   I am pasting code below.   Any help, advice or information would be really helpful.   Thanks in advance.

Here is the code for the list box as it is in the user control.
<pre>
<ListBox SelectionChanged="ListBoxImages_SelectionChanged" IsSynchronizedWithCurrentItem="True" Margin="8,40.76,8,174.91" x:Name="ListBoxImages" Grid.Row="1" ItemsSource="{Binding Path=Photos, ElementName=UCAscensionImageManagement, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" ItemTemplate="{DynamicResource DataTemplateImageList}">
          </ListBox>
</pre>

This is the user control, that contains the listbox.   It is in a datatemplate.
<pre>
<SG2_Ascension:UserControlAscensionImageManagement Margin="21.234,0,17.733,54" VerticalAlignment="Bottom" Height="475" x:Name="UCAIMEventPhotos" Width="615" Photos="{Binding Path=UCGeneralDataSeries, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>

Finally, this is the dependency property as it is coded in the user control
<pre>
public static DependencyProperty PhotosProperty = DependencyProperty.Register(
                  "Photos", typeof(GeneralDataSeries), typeof(UserControlAscensionImageManagement)/*,
                  new FrameworkPropertyMetadata(new PropertyChangedCallback(OnRatingChanged))*/
                                                                                                                                    );
            /// <summary>
            /// Photo objects.
            /// </summary>
            public GeneralDataSeries Photos
            {
                  get
                  {
                        return (GeneralDataSeries)GetValue(PhotosProperty);
                  }
                  set
                  {
                        SetValue(PhotosProperty, value);
                  }
            }
</pre>

Again, any help would be greatly appreciated.

On the ListBox you have

ItemsSource="{Binding Path=Photos, <code>ElementName=UCAscensionImageManagement</code>, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

In the usercontrol you have

x:<code>Name="UCAIMEventPhotos"</code> Photos="{Binding Path=UCGeneralDataSeries, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

I assume you mean to bind the ListBox ItemsSource to the UserControl Photos
property, correct?

If so, you used the wrong ElementName in the ListBox ItemsSource binding.

You could also try something like this:

ItemsSource="{Binding Path=Photos, RelativeSource={RelativeSource AncestorType={x:Type SG2_Ascension:UserControlAscensionImageManagement}}, Mode=OneWay}"

Thanks Mark,

It seems you are on to the solution.   The only error it's giving me is that it says "the type reference cannot find a public type named 'UserControlAscensionImageManagement'.

This is unexpected since the listbox, and thus this declaration, is occurring within the UserControlAscensionImageManagement XAML file.   Wow!

At any rate, let me know if you have any additional thoughts.   I am continuing to work on finding a solution on my end.

Thanks for any additional information you can provide.

Even after a rebuild?

Is the class marked public?

Hmmmm...haven't tried a rebuild. Also, yes the class is marked public. I will try a rebuild shortly.

Rebuilds usually erase all of my test data in the database and force me to start from scratch. However, I will try it and let you know.

Thanks again.
