I want to do the following

Hello all ,

I just sorted out my inheritance issues and now have an issue where an Xml element when serialized has xmlns="" inserted .

ie

<CommsMessage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:q1="http://tempuri.org/" xsi:type="q1:AckMessage">
<q1:MessagesToAck><q1:string>urn:uuid:11a072c0-4b78-44b1-b2ec-9ea6cda90b07</q1:string></q1:MessagesToAck>
</CommsMessage>

the proxy changes it to

<CommsMessage xsi:type="q1:AckMessage" xmlns="" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:q1="http://tempuri.org/">
<q1:MessagesToAck>
<q1:string>urn:uuid:11a072c0-4b78-44b1-b2ec-9ea6cda90b07</q1:string>
</q1:MessagesToAck>
</CommsMessage>

as you can see from the log

I could prob go to XmlSerializer but dont want to change the service.

Any ideas will be appreciated.

Hi all:

  When I used wcf ,I wanted that the class which implemented the contract  had a  parameter constructor.But as I did this, I got a error.  

Can anyone tell me how to realize what i want.

I am trying to execute 2 Addins in MS-Outlook 2007.

AddIn1 : Made using AddInExpress

AddIn2 : Made using VSTO

AddIn1 makes a folder in mail items of MS-Outlook 2007 and when we select that it starts functioning.

Addin2 works starts functioning when a contact item is open in new inspector window. It displays a CustomTaskPane that executes a standalone application.

I have tested the following scenarios.

1) AddIn2 fires New Inspector Event when MS-Outlook 2007 is started and first contact is opened in new Inspector.

2) AddIn2 does not fire New Inspector Event when contacts are opened after closing the New Inspector window

3) Addin2 does not fire New Inspector Event when we click the folder created by AddIn1.

Can any one help me why New Inspector event does not fire in some cases

I am currently writing an add-in for Outlook 2007 with VSTO 2005 SE.

I have used a form region with a formRegionType of replaceAll which is associated in the registry to the message class IPM.Post.MyPost. My add-in works as expected with a compose and a read form.

I am in the stage of polishing the GUI with icons and proper ribbons. One requirement is to display the folder items with one of two icons depending on item status.

My initial thought was to define the <icons> in the form region manifest but it does not seem to have any effect.

< xml version="1.0" encoding="utf-8" >
<FormRegion xmlns="http://schemas.microsoft.com/office/outlook/12/formregion.xsd">
...
<icons>
<default>icon.png</default>
<read>icon.png</read>
<unread>icon.png</unread>
<window>icon.png</window>
</icons>
</FormRegion>

Note that there is no custom form. In tehse circumstances, what is the proper way to achieve the above

Thank you for your help.

I am trying to build a project in VS 2005 but I am getting the error:

Error 67 "sgen.exe" exited with code 1. C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Microsoft.Common.targets 1892 9 TAI.Util

This project had been building just fine earlier today. The only thing that happened between is I refreshed the web references in this project. As a test I added the same web references to a new project and it builds just fine.

I have created a binding style1 which binds SelectedItem to a DependencyProperty and is programmatically applied to a control.

If a style is applied to a control before making selection the binding works, but if a selection is made first and style is applied after that the selection binding will not work...

Is that a bug.. or am I missing something (Try this code and see if you hit the breakpoint)

I have a service I implemented using WCF and MSMQ, all is working great so far. However, I have a rather intense process and need to control the number of threads that are simultaneously running. I’ve searched google and the forums but no luck. Any pointers of where to look for this

Thanks

Hi,

I'm trying to suss out the best way to unit test presenters with WPF views in a multithreading scenario. This is easiest to explain via code. Here's a view interface:

public interface ISearchView
{
Dispatcher Dispatcher
{
get;
}

SearchCriteria SearchCriteria
{
set;
}

SearchResults SearchResults
{
set;
}

event EventHandler<EventArgs> PerformSearch;
}

The implementation of this interface is a WPF user control that binds various child controls to the search criteria to enable the user to edit the criteria prior to searching. The PerformSearch event is raised whenever the user clicks the search button. The Dispatcher property gets the view's dispatcher so the presenter can pass results back to it safely.

The presenter code looks something like this:

public class SearchPresenter
{
private readonly ISearchView _view;
private readonly SearchCriteria _searchCriteria;

public SearchPresenter(ISearchView view)
{
_searchCriteria = new SearchCriteria();
_view = view;
_view.SearchCriteria = _searchCriteria;
_view.PerformSearch += View_PerformSearch;
}

private void ViewPerformSearch(object sender, EventArgs e)
{
DoSearch();
}

private void DoSearch()
{
_view.Results = null;

ThreadPool.QueueUserWorkItem(delegate
{
//search logic is here - it might take a while to execute

//search is finished - assign results to view
_view.Dispatcher.Invoke(DispatcherPriority.Send, new AssignHandler(Assign), results);
});
}
}

This all works fine and the beauty is that the view has no idea that the search is taking place on a separate thread. It doesn't need to know. We could change the presenter so that it is single-threaded or only switches to a separate thread in certain circumstances and the view would be none the wiser. Also, the view code is kept much simpler as a result.

The problem occurs during unit testing and, specifically, mocking the view's interface. The Dispatcher class is sealed and only has private constructors. The only way to get a Dispatcher is via the static CurrentDispatcher property. This makes it extremely cumbersome and hard, if not impossible, to unit test this code.

I have thought of only a couple of workarounds:

1. Put the thread-safety code into the view implementation, and just have the presenter assign the results directly rather than via the dispatcher.
2. Define my own IDispatcher interface and two implementations of this interface: DispatcherWrapper and MockDispatcher. DispatcherWrapper would wrap WPF's Dispatcher class and MockDispatcher would be used in unit testing. Views would expose an IDispatcher instead of a Dispatcher.

I don't like option 1 because it complicates the view implementation and requires it to understand the threading context in which it is running. I don't like 2 because, well, it's ugly and requires more work.

Any help much appreciated.

Thanks,
Kent Boogaart
