I recently started a job at a company doing software testing. The company has a XBAP application where we record our test case data, however all the controls (buttons, labels, tree nodes, etc.) are all in Chinese. Since I'm only person on the test team who doesn't speak/read Chinese, the developers in the company aren't willing to translate the entire application. Right now I have to resort to having someone with me to translate as I use the application.
What I'm hoping to do is develop an application where I can hover over/select a control and have the application translate the underlying text using Google (or some other translation software). I'm hoping this is somehow possible, as it would make my life a lot easier and increase my productivity, but I don't even know where to begin.
I've tried searching on Google with very little luck. The only thing I found that seems like it may be able to help is the System.Windows.Automation library, but I haven't found any examples that are applicable to my situation.
Is there someway that this can be done through a .NET application or an IE plug-in? Any suggestions or links to tutorials/examples on how I can get started on this would be greatly appreciated.
Thanks in advance for any help in this matter.

Isn't there a browser function/widget/thingy that acts as a magnifying glass, this may be the way to get the part of the screen under the mouse, grab that as an image, do a bit of contrast comparing to get the shapes, turning that into unicode may be a challenge, I expect Google has an api for their translate tool.
Just some thoughts, I have no idea whether all that can all be done and it may be simpler to internationalise the original app!

I wish they would just internationalize the application; I even offered to do it but they won't give me the source code (even though they know my long history of programming experience). The computer has IE10 on it and the only thing I see is a menu option that says "Zoom (100%)" but it is grayed out.

Am using Datagrid,where am getting an extra column header at the end.i bind the values from server to Datagrid thru 'Tag' property.How to remove the extra column header in this case.
|

A DataGrid Column could be hidden, but I dont think you can remove it...
|
|

The DataGrid by default generates its columns automatically. If you set its 'AutoGenerateColumns'-Property to False you can prevent this and maybe the extra column disappears by doing so.
Additionally you can define all the columns manually like so:
<DataGrid>
<DataGrid.Columns>
<DataGridTextColumn Header="Test" />
<DataGridTextColumn Header="Test2" />
</DataGrid.Columns>
</DataGrid>
If you disable auto generation and define your own columns there should appear no additional columns in the DataGrid.

Are WinForms components inside a WinformsHost element rendered with maximum possible z-index?
They always seem to overlap any WPF wlement, even with a higher Z-Index. Anyways to fix this? This is really causing much trouble when trying to embed a lengthy WinFormsHost component in a scrollable.

It's called the Airspace issue. It's fixed in .NET 4.5.

XP doesn't support .NET 4.5. Does it?

Are you sure? From what I've seen, there was a fix in the beta, but they removed it from the final release.
1.3.10 Windows Presentation Foundation (WPF)
1.3.10.1 HwndHost feature has been removed from WPF in the .NET Framework 4.5 Beta
The .NET Framework 4.5 Developer Preview included a WPF HwndHost redirection feature. However, this feature had several known issues and has been removed from the .NET Framework 4.5 Beta. It will not be included in any future releases.

You're right. Pete Brown, at Microsoft, promised me this would be in and as it wasn't something that I was affected by, I didn't follow up to see if it was delivered. This makes me pretty angry.

I have several datatemplates defined in a resource dictionary (in Resources project)
My application is in a separate project that references the Resources project. Appropriate datatempalte is loaded depending upon the object that is set to the datacontext during run time. Some of these datatemplates have buttons. How do I handle the click event of these buttons. I tried eventsetter but got XAML errors abt not being able to set eventhandler.
Thanks

Templates work only with triggers. These triggers are use to set various properties of the button.
See this for a more detailed understanding:Triggers in WPF[^]
ClickEvent is handled in code. It is completely independent from Triggers. You should be able to attach an event handler in the XAML declaration like this.
<Button x:Name="button1" Click="button1_onClick" Template={StaticResource MyTemplate} />
In code:
private void button1_onClick(object sender, RoutedEventArgs e)
{
}
See MSDN for more details:
Button Class[^]
ButtonBase.Click Event[^]

Thanks Amitosh S.M. for your reply.
I ended up binding a command to the button in datatemplate. And then defining this command as a property in my class. Worked pretty well.
<Button Name="btnControl" Canvas.ZIndex="10" Canvas.Left="175" Canvas.Top="25" Content="ICOM"
MaxWidth="75" MaxHeight="75" Style="{StaticResource ICOMButtonStyle}" Command="{Binding LaunchControlModule}"/>
Public ReadOnly Property LaunchControlModule() As ICommand
Get
Return New ViewModelCommand(AddressOf HandlerLaundControlModule)
End Get
End Property
Private Sub HandlerLaundControlModule()
ShowControlModule = True
End Sub
Public Class ViewModelCommand
Implements ICommand
Private _handler As Action
Public Sub New(ByVal handler As Action)
_handler = handler
End Sub
#Region "ICommand Members"
Public Function CanExecute(ByVal parameter As Object) As Boolean Implements System.Windows.Input.ICommand.CanExecute
Return True
End Function
Public Event CanExecuteChanged(ByVal sender As Object, ByVal e As System.EventArgs) Implements System.Windows.Input.ICommand.CanExecuteChanged
Public Sub Execute(ByVal parameter As Object) Implements System.Windows.Input.ICommand.Execute
_handler()
End Sub
#End Region

I'd like to get your thoughts on this design...
So I am writing some software for personal use. I'm an independent developer, and I wanted to put together an app to track the work I'm doing and handle invoicing and billing. Conceptually I understand what I want, but programmatically I am working on the design. This is more about me learning than producing an app.
So, I am building this WPF/MVVM app in components. Most pieces are user controls. I decided that I would use relay messages to communicate between the user control a& its host.
For example, the Client View is found in the Client Center.
Each Client is viewed in its own tab in the Client Center. The Client Center has a toolbar with New, Edit, Save, Cancel and Print buttons. Since the center doesn't really know about the Client views in the tabs, the Center will broadcast a message for each function. The Client Center has an instance of a TabManager class, which is a collection of TabItems. The TabItem's Tag property contains the PK of the entity in the tab's content. So, this is available in the View Model.
As an example, when the Save button on the Client Center toolbar is clicked, then it does:
ClientViewSaveMessage message = new ClientViewSaveMessage
{
Clientid = getActiveTabEntityPK()
};
Messenger.Instance.Send<ClientViewSaveMessage>(message);
Then in the client view I have
public ClientViewModel
{
messenger.Instance.Register<ClientViewSaveMessage>(p => receiveSaveMessage(ClientViewSaveMessage)p)
}
and then the receiveSaveMessage
private void receiveSaveMessage(ClientViewSaveMessage message)
{
if(this.Client.Id == message.ClientId)
{
saveChanges();
}
}
This technique has the advantage of decoupling all the components. So far it's working well. It's easy to develop, and so far, easy to maintain.
A drawback might be that I will need a lot of messages. I could make one message that has different properties...
Any way, I'd like to hear what you guys think.
Thanks

2 things come to mind. You have low expectations of your client base (reasonable in an independant developer) as you are using a tabcontrol as your client collection UI. I would use a grid. In the late 90 after about 5 years of consulting I had well over 50 organisations I was keeping tabs on, once a client or even a quote always a potential.
One reason not to use a messaging paradigm is that it is a bitch to maintain, there is no direct link between the firer of the message and the consumer of that message. a bitch to support.

I never said that. I said when a client is opened, it's opened in a new tab in the client center. There is a list of clients on the side .

That's what I said in my OP. Other than that, I cannot see any reason not to use this design,

Ah somewhat like the outlook bar, that makes sense.

Yeah but support is a major factor in the cost of an app and we will go a long way to make it easier for the next poor sod who has to support the app.

SO far it seems to be working well. Overall it's very little code, but the number of message classes is growing. I think that's where the confusion might come in. I could make one generic message class.
As far as knowing who sent a message, the call stack shows that. But I understand what you're saying.

Can you describe in one paragraph how you constructed your dynamic tab control. I have a similar requirement (max 5 tabs). If so please email me direct (your email is disabled on the messages).

I'm not sure what you mean by "constructed your dynamic tab control.

I was under the impression your tabcontrol populated the tabs and content based on data rather than at design time. I have a number of ideas how to achieve this but I am trying to reduce the experimentation time required to get it working and was hoping you had already researched this and had some guidance or links to examples you had used.
