    - Need some pseudo code for a "simple" scenario Hi guys, Here's my dilemma. I have a canvas hosting a bunch of PathGeometry's that can be dragged around and re-positioned etc. Keeping in mind that these are all very non rectangular shapes, I'd like to be able to label the Filled areas of the shapes with text. So the end result would be that both the shapes AND their corresponding text would move in unison when I darg the shapes about. Any ideas on what the easiest way to achieve my goals is Thanks!

    - Transitioning to WPF I think I know what you are trying to make. We might be in the same industry and making competing applications . No reason to not give a hand though. Unfortunatly, I don't think you'd be able to use WPFs JPEG decoder with this technique because it will just reallocate a new BitmapSource each time. Your best bet for performance is a DirectShow based solution (first hack), this way the video will be rendered via the MediaElement. I made a DirectShow source filter for fun that took a custom URL, like "mjpeg://address ort/path_to_mjpeg". I was able to pass that URL to a MediaElement and it loaded up perfectly and only had a minor performance hit when compared to a raw directshow implementation. Unfortunatly, this is not an easy answer. Learning DirectShow can be a pain. I wish you luck. Hopefully you don't have to drop down to using Win32 Interop (Host your legacy controls in WPF). Nobody likes doing that -Jer Tag: Windows Presentation Foundation (WPF) Save an ImageSource/BitmapSource/BitmapImage to file Visual Studio 2008

    - Optional arguments consuming WCF service. Hi, I am using basicHttpBinding to create a WCF service that is being consumed from a Studio 2005 web service reference. All the scalar arguments to the method calls are accompanied by a bunch of horrible IsSpecified boolean arguments. If I wanted such a cludgy interface I would have added the booleans myself How do I specify that these arguments are in fact not optional The client code looks terrible. I wish to make the service nicely backward compatible. I have tried adding [WebMethod] attributes as it was suggested that it would help, but alas, it does not.

    - Connection Issues Hello We are experiencing some problems with connections to the server in one the applications of a customer. We have an scenario in which various clients connect to one server. As the server acknowledge clients of some operations we are using a custom dualHttp binding (it compress messages). < customBinding > < binding name = " DualHttpCompressionBinding " closeTimeout = " 00:00:30 " openTimeout = " 00:00:30 " receiveTimeout = " 23:59:59 " sendTimeout = " 00:01:00 " maxConnections = " 100 " > < reliableSession inactivityTimeout = " 00:10:00 " maxPendingChannels = " 128 " maxTransferWindowSize = " 40 " ordered = " false " /> < compositeDuplex /> < oneWay maxAcceptedChannels = " 100 " > < channelPoolSettings maxOutboundChannelsPerEndpoint = " 100 " /> </ oneWay > < gzipMessageEncoding innerMessageEncoding = " mtomMessageEncoding " /> < httpTransport useDefaultWebProxy = " false " /> </ binding > </ customBinding > As we need several clients, we have changed also the service throttling . < serviceThrottling maxConcurrentCalls = " 100 " maxConcurrentInstances = " 100 " maxConcurrentSessions = " 1000 " /> with this configuration we were able to connect only 25-30 PCs to the service. Other clients trying to reach the service throw this exception: “This request operation sent to http://acindar69/SSMWebHost/Service.svc did not receive a reply within the configured timeout (00:01:00). The time allotted to this operation may have been a portion of a longer timeout. This may be because the service is still processing the operation or because the service was unable to send a reply message. Please consider increasing the operation timeout (by casting the channel/proxy to IContextChannel and setting the OperationTimeout property) and ensure that the service is able to connect to the client).” To solve this, we expose the same service in 2 different endpoints and configurate some clients to connect to one of the endpoints and the others to the other endpoint. Like this, we could run around 40 clients, but keep having the same exceptions when trying to connect some more. Although We have “solve” the problem for some number of clients, the solution is clearly not the best. We must create a new endpoint (exposing exactly the same service) for every 25-30 clients. My impression is that there must be some configuration limiting endpoints not to accept more than 30 connections. Any clue on how can we run more clients without adding new endpoints Tag: Windows Presentation Foundation (WPF) Save an ImageSource/BitmapSource/BitmapImage to file Visual Studio 2008

    - How to get, change, and save values from an entitiy using Entity Framework and LINQ? Hi all, for a project I have, my team decided to try working with Entity Framework and use LINQ to query the entities. To make my question more visible, I've also embedded a simplified code of our project which you can see below. We're using 3-Layer architecure (Presentation, Business, Data). The Main class below represented the Presentation Layer, and both getParticipant(...) and saveParticipant(...) methods are to be placed in the data layer. What I want to do here is : 1. Create a participant object in the presentation layer (Main class), using incomplete information (here in the sample the Participant_ID). 2. Get the rest of the information using a LINQ query in getParticipant(...) method, and save it to the created object. 3. Change the information of the entity and save it using saveParticipant(...) method As you can see, the context to the entity framework is only available in get and saveParticipant(...) methods of the data layer, this is intentional for security reasons. The problem arise when I call the saveParticipant(participant) method, practically forwarding the participant object to the "data layer". I don't know which method from the entity framework to call to incorporate the changes to the entities. I tried using "context.Attach(iParticipant);" to attach the input to the context, but then we get this error "Message="Entity can not be attached to multiple change trackers." eventhough I've detached them 1st in the getParticipant(...) method. I tried just using the context.AddToParticipant(iParticipant) method, but it failed by giving out "The entity cannot be added to the ObjectStateManager because it already has an EntityKey attached to it.", which is understandable I think the participant object have all the information needed for the entity framework to work with. any suggestion is very appreciated :-) Thanks in Advance, b4st -------------------------------------------------------------------------------- using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace test { class Program { static void Main(string[] args) { EntityFrameworkModel.Participant participant = new EntityFrameworkModel.Participant(); participant.Participant_Id = 1; participant = getParticipant(participant); participant.First_Name = "Pete"; saveParticipant(participant); } public static EntityFrameworkModel.Participant getParticipant(EntityFrameworkModel.Participant iParticipant) { using (EntityFrameworkModel.Entities context = new EntityFrameworkModel.Entities()) { var firstParticipant = (from fp in context.Participant where fp.Participant_Id == iParticipant.Participant_Id select fp); context.Detach(firstParticipant.First<EntityFrameworkModel.Participant>()); return firstParticipant.First<EntityFrameworkModel.Participant>(); } } public static void saveParticipant(EntityFrameworkModel.Participant iParticipant) { using (EntityFrameworkModel.Entities context = new EntityFrameworkModel.Entities()) { //... context.SaveChanges(); } } } } ---------------------------------------- Tag: Windows Presentation Foundation (WPF) Save an ImageSource/BitmapSource/BitmapImage to file Visual Studio 2008

    - ClipToBounds property on Ellipse, Rectangle and Path Thanks SerialSeb for the reply But this really isn't the type of functionality that I am after. The Clip property seems to be more of a selection tool (as in what part of the ellipse to I want to show) rather than a way of saying 'i have these 4 different images, shapes, movies, etc that I don’t want to show out side the boundary of the container that holds them'. Were the containers its self can be any Geometric shape When working this would act the exact same way as ClipToBounds does with Panels and Boarders, but both of those objects can only be rendered as shapes with 90 degree corners. Now I know that all UIElements have ClipToBounds but it doesn’t make any sense to me why Ellipse, Rectangle and Path do when you can’t have anything inside these objects. If you could, then it would make logical sense and my problem would be solved. But as it stands the property does nothing… So does ClipToBounds have any use on an Ellipse, Rectangle and/or Path So given all this and the fact that ClipToBounds doesn’t seem to work in the context of an Ellipse, Rectangle and/or Path, is there another way of doing what I need to do so that actually works on non rectangular objects.

    - 2d Mouse Coordinates to 3d You can use the 3D Tools library created by Daniel Lehenbauer. You can get it here http://www.codeplex.com/3DTools Besides other goodies it contains a MathUtils helper class that performs the calculations you are looking for. For example to convert a point in 3D space to screen coordinates you would do the following: Code Snippet Viewport3DVisual viewport; bool success; Matrix3D screenTransform = MathUtils .TryTransformTo2DAncestor(myVisual, out viewport, out success); if (success) { Point3D scenePoint = new Point3D (1, 1, 0); Point3D screenPoint = screenTransform.Transform(scenePoint); ... } The X and Y coordinates of screenPoint will be expressed as relative to viewport area. This allows for very easy positioning of 2D content over 3D objects. Tag: Windows Presentation Foundation (WPF) Save an ImageSource/BitmapSource/BitmapImage to file Visual Studio 2008

    - MenuItem.Command - multiple binding Hello, Setup: In my app, I have a MenuItem (mi) and I’ve hooked up a Command (cmd) to it. My app has a main window (win). The window has a frame (frm) that I use to navigate to page (pg1). In win.ctro I add a commandbinding for cmd. When I go to menu item and select the mi, the cmd fires. In pg1.ctor I have another commandbinding for cmd. Problem: When frm navigates to pg1, and I select the mi, the win.cmd fires not the pg1.cmd. My findings so far: a) I think this has to do with the CommandTarget setting. But I don’t seem to be able to give keyboard focus to the pg1 after it is loaded. Is ther a way I can do this b) I put a button btn on pg1 and set the btn.Command to the same binding as the mi. When I click the button, I get the pg1.cmd behavior. THEN if I click the mi I get the pg1.cmd behavior. So I thought if I set btn.IsDefault=true, I’ll somehow signal that it is the page that has focus. But it doesn’t work that way. I have to click the button and then pg1.cmd gets linked up to the mi. Thanks in advance.

    - ListViewColumnHeader Hello, do you want to filter the data based on what the user types in the TextBox If so, I guess what you want is the TextBox’s Text property. Since the TextBox is in a template, we can’t get it directly in the code. But here’s a walk around: Create a TextBlock outside the template, set its Visibility property to Collapsed, so the user won’t see it. Give it a name such as text1. Now we can bind the TextBox’s Text in the template to the TextBlock’s Text: Text = " {Binding ElementName=text1, Path=Text} " Since this binding is two way by default, whenever the TextBox’s Text updates, the TextBlock’s Text will also be updated. And we can access the TextBlock in our code since it’s not in a template. So we’ll get the text the user typed.

    - Return large result sets using WCF with wsHttpBinding Hi, We are developing a new financial solution using WCF as communication programming model, in order to be accomplished with new customer requirements: SOA and interoperability. We have some WCF services (.svc) published in an Win2003/IIS6 server providing corporative services for some client applications. Since these client applications functionalities are built using composition of corporative services, all services are configured to use wsHttpBinding because we are using new transaction flow feature and also to guarantee interoperability with other WS* consumers. We are having problems when some services must return large results to client applications like financial transaction lists to be processed by those. We have already tried to configure these services with "Mtom" message encoding instead of "Text", we increased maxReceivedMessageSize parameter. We have done other configuration changes like defining readerCotas parameter, increase closeTimeout, sendTimeout, openTimeout parameters and nothing what we have done is making difference. When a list returned by services is larger than 1000 registers the exception below was thrown: An existing connection was forcibly closed by the remote host.

    - Invalid association mapping error in Add() I just ingested a Schema using the a Linq to SQL DBML file in the designer. All looked good and seemed to be properly referenced. Then i tried to add a row to a lookup table like below: Code Snippet using (MyDataContext db = new MyDataContext(ConfigurationManager.ConnectionStrings["MyDB"].ConnectionString)) { track_status_enum x = new track_status_enum(); x.enum_value = TrackStatus.Archive.ToString(); x.track_status_id = (byte)TrackStatus.Archive; feed_item_comment_track f = null; db.track_status_enums.Add(x); db.SubmitChanges(); This resulted in the following error on the Add() line: Invalid association mapping for member 'Feedelity.DAL.track_status_enum.feed_item_comment_tracks'. 'Feedelity.DAL.feed_item_comment_track' is not an entity. track_status_enum is a lookup referenced by a bunch of tables as a status field and feed_item_comment_track is one of them. Since i wasn't adding anything to those tables, I don't even know why it's interacting with them on this add, anyhow, but regardless, feed_item_comment_track is defined the same as track_status_enum, so i expect it to be an entity for linq. Any suggestions what this error actually means and where to start troubleshooting thanks arne Tag: Windows Presentation Foundation (WPF) Save an ImageSource/BitmapSource/BitmapImage to file Visual Studio 2008

How can I save a ImageSource, BitmapSource, or BitmapImage to a file.

I have an Image in which the source originally came from another file that contained serialized GDI+ System.Drawing.Bitmaps.

Now I need to save the image to a ".bmp", ".png" or some other format.

How can I do this with performance in mind I can obviously convert it back to a System.Drawing.Bitmap and call bitmap.Save(), but is there a better way

Take a look at the JpegBitmapEncoder class as an example of how to save a Bitmap to a jpeg. There are other encoders as well, such as PNG.
