You can use a toggle button. That has the checked property.
http://msdn.microsoft.com/en-us/library/system.windows.controls.primitives.togglebutton.aspx
Example with an image in the button:
<togglebutton tooltip="Pointer" tag="Pointer" ischecked="true">
<image source="Resources\Icons\PointerHS.png" />
</togglebutton>
Hope this helps,
Bart
EDIT: somehow it did not display all code so I ignore HTML tags now.

Greetings,
Create a handler for the slider value changed event. Then in that event handler, set the sound volume of your player. Of course, make sure that whatever values you use in the slider correspond proportionately to the sound volume of your audio player.
I am doing the same thing in my project and here is the code I use:
<pre>
private void OnSliderMusicVolumeValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
{
if (myMusicManager != null)
{
myMusicManager.Volume = SliderMusicVolume.Value;
}
}
</pre>
myMusicManager is just the name I gave to a class that wraps the wpf media player. Below is where I get and set the volume using the appropriate conversions.
<pre>
public double Volume
{
get
{
return myMusicPlayer.Volume * 10; // myMusicPlayer is the actual wpf media player
}
set
{
myMusicPlayer.Volume = (value / 10);
}
}
</pre>
I hope this helps, let me know if you have any more questions.

Need a chat application in wpf using TCP/IP service,not using wcf

You having an issue doing it or just asking if anyone here has one they are willing to give?
WPF does not really stop you form using raw sockets unless you are doing an XBAP, app and then you may need to adjust some security to allow it to work.
Do you have a specific aversion to using WCF or do you have a hard requirement that you must use raw sockets.

Listen PartSocket newsock = new Socket( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );
IPEndPoint iep = new IPEndPoint( IPAddress.Any, 2091 );
newsock.Bind( iep );
newsock.Listen( 5 );
newsock.BeginAccept( new AsyncCallback( AcceptConn ), newsock );
void AcceptConn( IAsyncResult iar )
{
Socket oldserver = ( Socket )iar.AsyncState;
client = oldserver.EndAccept( iar );

receiver.Start();
}

{
int recv;
string stringData;
while( true )
{
recv = client.Receive( data );
stringData = Encoding.ASCII.GetString( data, 0, recv );
if( stringData == "bye" )
break;
}
stringData = "bye";
byte[] message = Encoding.ASCII.GetBytes( stringData );
client.Send( message );
client.Close();
return;
}

client = new Socket( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );
IPEndPoint iep = new IPEndPoint( IPAddress.Parse( "127.10.27.61" ), 2091 );
client.BeginConnect( iep, new AsyncCallback( Connected ), client );
void Connected( IAsyncResult iar )
{
client.EndConnect( iar );
Thread receiver = new Thread( new ThreadStart( ReceiveData ) );
receiver.Start();
}
My code is like thisduring the connection part error happends,May be due to 2 threads,how can i solve the same

Good afternoon.
I cant seem to get a combobox to select a value using Binding. I have a small example that re-creates the issue, I want the combo to have selected Yellow (_colour is set to that on creation) when it first loads. Hope that makes sense
Code is below, just window1 and a class called ViewModel. TIA for any help 
Window1.xaml
<window x:class="ComboBoxTest.Window1" xmlns:x="#unknown">
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<grid>
<combobox margin="92,122,66,116">
ItemsSource="{Binding Path=Colours}"
DisplayMemberPath="Description"
SelectedItem="{Binding Path=SelectedColour, Mode=TwoWay}"
Grid.Column="1"
Grid.Row="8"
IsSynchronizedWithCurrentItem="True"
/>
</combobox></grid>
</window>
Window1.xaml.cs
using System.Windows;
namespace ComboBoxTest
{
public partial class Window1 : Window
{
public Window1()
{
this.DataContext = new ViewModel();
InitializeComponent();
}
}
}
ViewModel.cs
using System;
using System.Collections.Generic;
using System.Windows;
namespace ComboBoxTest
{
public class Colour : IComparable
{
public string Description { get; set; }
#region IComparable Members
public int CompareTo(object obj)
{
return string.Compare(((Colour) obj).Description, this.Description);
}
#endregion
}
public class ViewModel : DependencyObject
{
public List<colour> Colours
{
get
{
List<colour> retval = new List<colour>();
retval.Add(new Colour { Description = "Blue" });
retval.Add(new Colour { Description = "Green" });
retval.Add(new Colour { Description = "White" });
retval.Add(new Colour { Description = "Yellow" });
retval.Add(new Colour { Description = "Red" });
retval.Add(new Colour { Description = "Silver" });
return retval;
}
}
private Colour _colour = new Colour { Description = "Yellow" };
public Colour SelectedColour
{
get { return _colour; }
set { _colour = value; }
}
public static readonly DependencyProperty SelectedColourProperty =
DependencyProperty.Register("SelectedColour", typeof(Colour), typeof(ViewModel));
}
}

Thanks for your reply, this was a test project and you are right i did not have the Selected Colour correct, i have changed it and it still does not work, so will look at INotifyPropertyChanged, and let you know.

Cant get that working either, If anybody would be able to convert my sample app, i would be greatful

Does it work if you implement your Colour class something like this?
public class Colour
{
public string Description { get; set; }
public override bool Equals(object obj)
{
return this.Description == (obj as Colour).Description;
}
public override int GetHashCode()
{
return base.GetHashCode() ^ this.Description.GetHashCode();
}
}
...and your SelectedColour dependency property:
public static DependencyProperty SelectedColourProperty =
DependencyProperty.Register("SelectedColour", typeof(Colour), typeof(ViewModel));
public Colour SelectedColour
{
get { return (Colour)GetValue(SelectedColourProperty); }
set { SetValue(SelectedColourProperty, value); }
}

Many thanks for your reply.
That still does not do what i want, i am starting to think that i am going about this the wrong way 
Put simply what i need is a combobox with a datasource of list of my objects (all the same type). Then when the form loads i want the combobox to have preselected an object of my choice (what ever was saved in xml/db)
I am new to wpf and the mvvm pattern, and this is getting a bit frustrating!!
ps for info i changed the colour class to the following as the other throw an exception
public class Colour
{
public string Description { get; set; }
public override bool Equals(object obj)
{
if(obj.GetType()== typeof(Colour))
return this.Description == ((Colour) obj).Description;
return base.Equals(obj);
}
public override int GetHashCode()
{
return base.GetHashCode() ^ this.Description.GetHashCode();
}
}

I have a MFC dll, which one inherit the CFormView and I add a textbox in that FormView. I want to load that dll from WPF and display it in the window as a control. If anyone have an idea about this, please help me.

Why would you want to do this? It's easy enough (i.e. trivial) to do exactly this in WPF, so why would you want to go to all the trouble of adding in an external DLL to do this? BTW - I'm not the one who voted 1.

Hi All,
I've just started looking into this in relation to an app I've made. It's a fairly simple app, most of the pages just have a handful of controls (the main one being Infragistics Grid) spread over a few pages. The app has been designed and implemented using Prism (Composite).
When I first launch the app I'm seeing nearly 60Mb of ram in use before the application has opened any data files. I'm currently going through the WPF Performance Suite tools to see what this shows up. Any tips would be good!
Anyone else experiencing anything like this with their apps?
