Just how big do you expect your images to be? Basically you have two choices - store your image in a database or store your image in the filesystem. If you're using SQL Server 2008, you can use a FILESTREAM datatype where the image data is stored on the filesystem but SQL Server is in control.

I hope to be clear,
Thanks a lot,

How to change property of other element

Hi all,

I'm quite new to WPF and have a small problem with the template for the ComboBox control. I'm trying to change the ComboBox's border color, when the text box has the keyboard focus. Unfortunately, VS tells me, that I'm addressing an unknown item.

Here's a small code snippet to explain it:

<ControlTemplate TargetType="{x:Type ComboBox}">
<Grid>
<Border Background="Green" x:Name="ComboBoxBorder">
<Grid>
<ToggleButton ... />
<TextBox Visibility="Hidden" x:Name="PART_EditableTextBox" ...>
<TextBox.Template>
<ControlTemplate>
<ControlTemplate.Triggers>
<Trigger Property="UIElement.IsKeyboardFocused" Value="True">
<Setter Property="Background" TargetName="ComboBoxBorder" Value="Blue" />
</Trigger>
</ControlTemplate.Triggers>
<ScrollViewer x:Name="PART_ContentHost" Focusable="false" />
</ControlTemplate>
</TextBox.Template>
</TextBox>
</Grid>
</Border>
</Grid>

</ControlTemplate>

If somebody could explain to me, why I cannot address the ComboBoxBorder item from the TextBox, that would be really nice. And I would appreciate a working piece of code Smile | :)

Thanks in advance,
Jammni+

The trigger is not working because it is inside the TextBox control template, but the ComboBoxBorder is in the ComboBox control template. You could try moving the trigger to the ComboBox level.

Thanks for your answer. But how can I achieve that? I've no idea, how to address the textbox from the border. E.g. I inserted an EventTrigger like:

<Border.Triggers>
<EventTrigger RoutedEvent="GotKeyboardFocus" SourceName="PART_EditableTextBox">
<Setter Property="Background" Value="Orange" />
</EventTrigger>
</Border.Triggers>

But the compiler tells me, that GotKeyboardFocus cannot be converted to a RoutedEvent Frown | :-(

Thank you for your help Smile | :)

WCF ServiceHost shuts down when not in console application

That's exactly what I needed. I always tried to apply the trigger to the border or to the textbox itself :-/

Hi,
I am just starting to learn WCF. In all the examples I've seen so far, the SerciveHost was initialized inside a console application and remained listening until the console was closed.
I am trying to have it initiated from inside a winform app. I have a button which triggers this method:
private void StartServer()
{
using (host = new ServiceHost(typeof(DataBase.DataBaseService ), new Uri("http://localhost:8000/DataBaseService")))
{
host.AddServiceEndpoint(typeof( DataBase.IDataBaseService),
new BasicHttpBinding(), "DataBaseService");

host.Open();
}
}

As soon as the method reaches the end, host.Status is set to Closed.
Is there any way to stop this?

The problem you're facing here is that you are disposing of the host immediately after opening it. What you might want to do here is to make host a member instead, then initialise it in StartServer. In your Form_Closing method, you would want to close host.

private _host = null;

private void StartServer()
{
  _host = new ServiceHost(typeof(DataBase.DataBaseService ), new Uri("http://localhost:8000/DataBaseService"));
  _host.AddServiceEndpoint(typeof(DataBase.IDataBaseService),
    new BasicHttpBinding(), "DataBaseService");
  _host.Open();
}

private void StopServer()
{
  if (_host != null)
  {
    _host.Close();
    _host.Dispose();
  }
}

Call StopServer in the Form_Closing event.

I did have host as a member. I think the problem was using the 'using' statement. After looking at your code I dropped it and it works so thanks a lot.

Not a problem. For your information - the using statement here triggers a Dispose when the code reaches the end of the code block (which was the point I was trying to make).

What do you feel are the 3 biggest advantages of WPF over ASP.NET?

What do you feel are the 3 biggest advantages of WPF over Winforms?

It seems like WPF may be more time-consuming to develop in with fewer 3rd party controls.

Hell no. I can knock applications up in WPF either as quickly, or quicker than in ASP.NET. Try this[^] article (shameless plug Wink | ;)

). Try this[^] article by Karl about why his company chose WPF over ASP.NET.
