    - Why can't I get a TextBlock to Wrap text on MouseOver? Your code should work. How long is the text of Subject If it’s not long enough, of course it doesn’t need to be wrapped. Try to set a small Width, say, 50, for the ListView explicitly to see whether the text wraps when mouse over. Tag: Seperate Callback Processing

    - Hosted WebBrowser & Mouse Wheel First, what is IsVisible The WindowsFormsHost has a Visibility property whose value is Visible, Collapsed, or Hidden. The WebBrowser has a Visible property whose value is true or false. It looks like you’re using WindowsFormsHost’s Visibility here. I guess when the WindowsFormsHost becomes Visible, the WebBrowser hasn’t also become visible yet, so your set on Focus doesn’t work. You may try to use the WebBrowser’s VisibleChanged event instead.

    - Replacing custom UDP protocol with UDP-based WAS activation I have a system that involves tens of thousands of mobile devices and a single .Net Windows NT service exchanging information. The communication is done via UDP - over the public internet, using CDMA or 80211.b. A custom reliable protocol has been implemented in top of the UDP. The solution is not easily expandable and virtually impossible to load balance. Reading about UDP-based WAS activation - will this technology be appropriate to use for replacing the current system Will the UDP layer get isolated from the IIS (w3svc and others) Apparently so, but I am not sure how will state information be shared, if needed. If any insight on a similar topic - I would appreciate the input. Tag: Seperate Callback Processing

    - Feature Comparison With NHibernate If you look at a comparison of the scenarios supported between NHibernate and our upcoming version of the Entity Framework strictly from an ORM perspective, we'll support fewer scenarios in mapping, but we will give developers an opportunity to support more complex scenarios through stored proc and view mapping. We should create a blog post that explicitly shows those differences and will! Look for it on our blog site in the coming weeks Thanks, Dan Tag: Seperate Callback Processing

    - Controls do now flow correctly in a flow document I used the Textblock as a simplification. Actually the visual that I'm trying to put in a flowdocument is composed of several expanders, stacks, etc. The other reason would be just out of curiousity - I wonder if controls can flow like regular flowdocument elements (span several pages, etc).

    - MediaElement Scrubbing Issues OK, so I have tried a few things. I tried upping the keyframe frequency to one per second, and I have also tried using DivX instead of WMV. Neither of these has worked. Using a Windows Media Player control does not produce the same problems, but I can't really use that as a long term solution. I have also tried various other video files, and the same problem exists. Any other thoughts Tag: Seperate Callback Processing

    - Extend the last column in a GridView Ahh, my mistake. I missed the "View" part of GridView. Check out this thread . Despite the original poster giving up because the implementation provided by LeeD was not a 100% solution for him, the theory is still sound. All that needs to happen to support resizing of the list view is that the value converter needs to become a multi-value converter where the first parameter should be the ListView instance itself and the second its ActualWidth property.

    - Controlling sequential animations Hi, I see what you were doing. Are you new to .NET development In .NET (This was already true in WinForms, and is still true in WPF), the whole UI is run in one single thread (called, not without irony, the "UI thread" :-) So if you "spin" in this thread, you will block all the animations. That's a big no-no. This is probably why you thought you needed another thread, and a dispatcher. In .NET, we work a lot with events. There are tons of built-in events that you can handle, and if one event is missing, creating a new event is very, very easy. So that's really the way I would recommend you to follow.

    - want text box to highlight all existing text on focus You can easily handle it at the application level, it just requires a little more programming. Unofortunately routed events don't perculate up to the application level, so what you need to do is detect when a page is navigated to using Application.LoadCompleted , cast the Content property of the event args to a Page instance and add a routed event handler as I mentioned before that points to a method declared at the application class level. There is no declaritive way to control keyboard focus. You'll need to call the static Keyboard.Focus method or the IInputElement.Focus instance method. What you can do is, at the same point where you hook the routed event, you can also get the logically focused element of the page (originally set using the FocusManager.FocusedElement attached property as discussed previously) using FocusManager.GetFocusedElement and then call Focus on the resulting IInputElement instance.

    - RejectChanges functionality in ADO.NET Entity Framework Hello, I would like to know if the "RejectChanges" functionnality will be available in ADO.NET Entity Framework. For me, "RejectChanges" is used to UNDO the user modifications. "RejectChanges" is a different scenario than "Reloading" the entity because "reloading" means potentially "getting" the other users modifications made on the entity. If ADO.NET Entity Framework goal is to offer an alternative to DataSet/DataTable then I think the RejectChanges is needed. Unfortunaltly, I noticed that the "RejectChanges" method on class ObjectStateEntry (in ADO.NET Entity Framework in January 2007 CTP) had disapeared ! Will it be possible to perform a "RejectChanges" in the final version Thanks for your help. Tag: Seperate Callback Processing

    - Newbie: WCF without Admin rights Hi, Sorry if this is such an obvious thing (I've had a search on the internet but honestly can't find the answer). I want to build a simple WCF webservice for desktop applications to use. However, when I run my client app on Vista with non-admin users I get a message saying that my App is not responding. However, the same application runs great on XP. I then logged in as admin and modified some settings (adding a url acl) and the client application works okay. So my question is, can I write a WCF webservice which does not require you to be admin (and doesn't require an admin to previously set permissions) for my app to work If so, can anyone give me a code sample Thanks!

WCFNewbie

Why does the callback is block whenever a process is not finish. Is there a way to solve this problem I have many client that call the same process and callback it to the client that call that process but the problem is if the process that has been call isn't finish processing to the client who called him, the other client will wait until taht process is finish to be able to process, is there a way to have them process seperately or process them at the same time

By the way my service beahvior is this

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Reentrant)]

and my service contract is

[ServiceContract(SessionMode = SessionMode.Required

did I miss something

Re: Seperate Callback Processing

WCFNewbie

The host does not process the Callback separtely, Host callback are process per client callback thus if the callback is blocked other clients callback(s) will not be processed.

Re: Seperate Callback Processing

T.R.Vishwanath - MSFT

If you want the service to process requests from multiple clients concurrently you need to configure ConcurrencyMode.Multiple on the ServiceBehaviorAttribute.

Thanks
