WPF in an IFrame not updating

Gareth H28-Oct-08 5:34

28-Oct-08 5:34

I have created a WPF Browser Application in VS2008. I've then added to XBAP to my webpage in a IFRAME

<iframe height="600" width="800" src="http://server/application/ClientBin/WPFApplication.xbap" />

This works fine, and displays the WPF. The problem is, IE never seems to clear its cache and get the latest XBAP once I've updated the WPF control. It always looks at the old control.

I've set my cache to always update every time I visit a page, and I've also cleared my history etc but it still looks at the old version.

Does anyone know how to solve this?

Regards,
Gareth.

Open up a Visual Studio Command Prompt, then run "mage -cc". Basically, as long as the version is the same it will probably not pull the updated version.

Hi,

I have a simple code snippet that changes the color of a background of a boder using animation. How to define that in style? I am getting the error message saying that I cannot specificy TargetName.

<Border.Background><br />
                                <SolidColorBrush x:Name="brush"></SolidColorBrush><br />
                            </Border.Background><br />

Style looks like this:

<style x:key="ButtonStyle" targettype="{x:Type Button}" xmlns:x="#unknown">
<setter property="Template">
<setter.value>
<controltemplate targettype="{x:Type Button}">
<controltemplate.resources>

</controltemplate.resources>
<grid>

</grid>
<controltemplate.triggers>

</controltemplate.triggers>
</controltemplate>
</setter.value>
</setter>
</style>

You have to put everything in the appropriate place for it to work, then apply the style to the element you want

Thanks for reply! Is it possible to do that without defining a template? I believe that a simple style with 2 triggers would be enough

_iobuf28-Oct-08 8:15

_iobuf

28-Oct-08 8:15

Yes. I think you can just ignore the "template" setter.. so just erase the <Setter Property="Template> and the <Setter.Value> stuff all the way until the </Setter> tag. I think you can just put a <Style.Resources> tag and put all the triggers in there... I think.... I haven't actually made any sample of this, but if that doesn't work I can always try to find a solution instead of doing my job lol

Problem with using thread and event in WPF

You can do

<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Foreground" Value="{DynamicResource GenericButtonFontBrush}"/>
</Trigger>
</Style.Triggers>

Hello, I need to change content of Window2 in time. I use event to inform Window2 to change content and thread evoking event. To be easy, I only change content of Label in Window2 in time. Problem is, that content of Label isn´t changing when is thread sleeping and Windows "are not responding" and I don´t see anything in Windows 2. I see Label in Window2 only when my thread ends. I need to see Label with content "1", and in several seconds with content "2".... Could someone please have a look at my code and help me what I´m doing wrong?

Is there a reason that your architecture is so complicated? I can't see a lot of the code off to the side because of formatting issues here, but I can't see any reason why you need your code to be as complicated. Why not use an ObservableCollection if you need a collection of "changes"? If it's just updating a simple binding, take a look at using the DispatcherTimer.

Here's a simple object that uses the DispatcherTimer to update the time every second:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;
using System.Windows.Threading;
using System.Windows;

namespace MyNamespace
{
  /// <summary>
  /// This class is responsible for updating the time so that it displays propertly in the status bar.
  /// </summary>
  public class TimeManager : INotifyPropertyChanged, IDisposable
  {
    private DispatcherTimer _timer = null;
    private string _currentDateAndTime;

    /// <summary>
    /// Initialize a new instance of <see cref="TimeManager"/>.
    /// </summary>
    /// <param name="parent">The window that "owns" the status bar. This class uses the Dispatcher from that
    /// window.</param>
    public TimeManager(Window parent)
    {
      _timer = new DispatcherTimer(TimeSpan.FromSeconds(1), DispatcherPriority.Normal, new EventHandler(TimerTick), parent.Dispatcher);
    }

    /// <summary>
    /// Called when the timer updates.
    /// </summary>
    protected virtual void TimerTick(object sender, EventArgs e)
    {
      CurrentDateAndTime = DateTime.Now.ToString();
    }

    /// <summary>
    /// Called when the item updates.
    /// </summary>
    /// <param name="propertyName">The name of the property.</param>
    protected virtual void Changed(string propertyName)
    {
      if (PropertyChanged != null)
      {
        PropertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName));
      }
    }

    /// <summary>
    /// Get or set the current date and time.
    /// </summary>
    public string CurrentDateAndTime
    {
      get
      {
        return _currentDateAndTime;
      }
      set
      {
        if (_currentDateAndTime != value)
        {
          _currentDateAndTime = value;
          Changed("CurrentDateAndTime");
        }
      }
    }
    #region INotifyPropertyChanged Members

    public event PropertyChangedEventHandler PropertyChanged;

    #endregion

    /// <summary>
    /// Start the timer.
    /// </summary>
    internal void Start()
    {
      if (_timer != null)
        _timer.Start();
    }

    /// <summary>
    /// Stop the timer.
    /// </summary>
    private void Stop()
    {
      if (_timer != null)
        _timer.Stop();
    }


    #region IDisposable Members

    public void Dispose()
    {
      Dispose(true);
    }

    private bool _disposed = false;
    protected virtual void Dispose(bool dispose)
    {
      if (!_disposed && dispose)
      {
        Stop();
        _disposed = true;
        GC.SuppressFinalize(this);
      }
    }
    #endregion
  }
}

Here's a status bar (UserControl) that makes use of it:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace MyNamespace
{
    /// <summary>
    /// Interaction logic for StatusBar.xaml
    /// </summary>
    public partial class StatusBar : UserControl
    {
        private TimeManager _timeManager = null;

        /// <summary>
        /// Initializes a new instance of <see cref="StatusBar"/>.
        /// </summary>
        public StatusBar()
        {
            InitializeComponent();
        }

        /// <summary>
        /// Called once the control has loaded. We need to hook into this event rather than
        /// the constructor to set up the key manager.
        /// </summary>
        private void UserControl_Loaded(object sender, RoutedEventArgs e)
        {
            DependencyObject parent = this.Parent;

            while (parent != null && !(parent is Window))
                parent = LogicalTreeHelper.GetParent(parent);

            if (parent != null)
            {
                _timeManager = new TimeManager(parent as Window);
                TimePortion.DataContext = _timeManager;
                _timeManager.Start();
            }

        }

        /// <summary>
        /// When the control is unloading, we want to remove the time manager.
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void UserControl_Unloaded(object sender, RoutedEventArgs e)
        {
            if (_timeManager != null)
            {
                _timeManager.Dispose();
            }
        }
    }
}

I have modified the CellTemplate of a ListView with a custom control called EditBox which allows the user to edit the data in the ListView. The EditBox-class actually has a BeginEdit() function which I want to call, but how can I access the EditBox-instance?

Can we import 3DMax's models ( *.max files) in Expression Blend ?

If so , how can we do it ?

Many thanks in advance

I believe the .Max format is protected so it won't be possible to use .max files directly. Instead you might use .3DS. You may even consider importing the 3DS into Blend which can export to Xaml.

I don't know it there are Xaml exporters at the moment. But it should be too hard to write a simple exporter using MaxScript.

Dawn is nature's way of telling you to go to bed.

Pete O'Hanlon25-Oct-08 8:29

You can export 3DS files out to XAML using this[^]. I've not tried it, because I prefer working in Maya and Cinema4D, but it should do the job; and do let us know if it does won't you?
