  • Best practice to handle Parent Form Child Form relation using Presentation Model

    - by Rajarshi
    According to Presentation Model notes by Martin Fowler and also on MSDN documentation about Presentation Model, it is explained that the Presentation Model Class should be unaware of the UI class and similarly Business Model Class should be unaware of the Presentation Model class. The UI should databind extensively to the Presentation Model, the Presentation Model in turn will co-ordinate with one or more Domain/Business Model objects to get the job done. The Presentation Model basically presents the Domain Model data in a way to facilitate maximum data binding in UI, allowing the UI take as less decisions as possible and thus increase testability of Presentation behaviours. This also makes the presentation model class generic, i.e. agnostic of any particular UI technology. Now, consider there is a List form (say CustomerList) and there is another Root form (say Customer) and there is a Use Case of allowing to Edit a Customer from the CustomerList form on a button click. For simplicity of discussion, consider that some actions took place when Customer List is opened from menu (i.e. Customer menu clicked) and the Customer List has been shown from the Menu click event. Now as per the above Use Case, I need to open the Customer Root UI (single Customer) from the Customer List. How do I do that? Build necessary objects (BusinessModel, PresentationModel, UI) in click event of Edit button and call CustomerEdit UI from there? Build the CustomerEdit UI from Presentation Model Class and show UI from presentation model? this can be done in any of the two ways below - a. Create objects in the following sequence DomainModel-PresentationModel-UIForm b. Use Unity.Resolve(); Either ways, Presentation Model is violated as the P model now has to the refer the concrete UI assembly, where CustomerEdit is located. Also the P Model has to refer and use a WinForm directly making it less UI technology agnostic. Even though the violations are in theory and can be ignored, I would still seek the community's opinion about whether I am going wrong direction. Please suggest if there's a better way to call the Child Form from the List (Parent) Form. Rajarshi

  • MindMap in silverlight

    - by JAllen
    I need to put together a team to build a silverlight based application that will read an xml file and generate a Mind Map diagram based on that file. I am new to silverlight and I need to find out what skills do I need and how difficult is it to do something like this. I expect the typical Mind Map features available in a commercial Mind Map software, like the ability to open and collapse nodes and to move the nodes around the screen.

  • .NET SSH Port Forwarding

    - by Ronnie Overby
    I am trying to build in SSH port forwarding into a .net application that I am writing. I have tried using sharpSSH, but it requires the user to input their password every time, and I don't want that. I am going to handle storing the password. I have downloaded Granados, but there is basically zero documentation for it. While I sift through the Granados source, does anyone know how to accomplish port forwarding with Granados or any other free SSH library for .NET?

  • Expression Tree Binary Expression for an 'In' operation

    - by Adam Driscoll
    I'm trying to build an expression tree (still) but getting further! I need to create a BinaryExpression to perform an 'In' comparison between a Member and a collection of items. Hence, the expression should return true if the member is contained within the items. This obviously does not exist: Expression.MakeBinary(ExpressionType.In, memberExpression, constantExpression); constantExpression is a ConstantExpression of type IEnumerable while memberExpression is a MemberExpression of type T. How would I create such an expression?

  • Sequence reduction in R

    - by drknexus
    Assume you have a vector like so: v <- c(1,1,1,2,2,2,2,1,1,3,3,3,3) How can it be best reduced to a data.frame like this? v.df <- data.frame(value=c(1,2,1,3),repetitions=c(3,4,2,4)) In a procedural language I might just iterate through a loop and build the data.frame as I go, but with a large dataset in R such an approach is inefficient. Any advice?

  • Three20 JSON problem: Can deploy to simulator but not device (extThree20JSON)

    - by wgpubs
    Everything builds and runs in the simulator fine ... but when I attempt to run on device I get: "arm-apple-darwin10-gcc-4.2.1: ..../three20/Build/Products/Debug-iphoneos/libextThree20JSON+YAJL.a: No such file or directory" I check that directory and indeed the file doesn't exist. It does exist in the "Debug-iphoneosimulator" though (which I guess explains why it works in the simulator). So what gives and what can I do to correct this? Thanks

  • Can rpmbuild ingore files in buildroot?

    - by Noah Campbell
    I have a target directory that is checked into svn. I use the target as the --buildroot when I run rpmbuild. This causes rpmbuild to loose it mind because of the .svn directories in each directory. Is there a way to tell rpmbuild to relax? I looked at svn export target target-build, but it only knows about files tracked by rpm. Perhaps not a bad way to do it, but I'm not quite sure that is the best way.

  • Proxy settings with ivy...

    - by user315228
    Hi, I have an issue where in I have defined dependancies in ivy.xml on our internal corporate svn. I am able to access this svn site without any proxy task in ant. While my dependencies resides on ibiblio, that’s something outside our corporate, and needs proxy inorder to download something. I am facing problem using ivy here: I have following in build.xml <target name="proxy" <property name="proxy.host" value="xyz.proxy.net"/ <property name="proxy.port" value="8443"/ <setproxy proxyhost="${proxy.host}" proxyport="${proxy.port}"/ </target <!-- resolve the dependencies of stratus --> <target name="resolveTestDependency" depends="testResolve, proxy" description="retrieve test dependencies with ivy"> <ivy:settings file="stratus-ivysettings.xml" /> <ivy:retrieve conf="test" pattern="${jars}/[artifact]-[revision].[ext]"/><!--pattern here specifies where do you want to download lib to?--> </target> <target name=" testResolve "> <ivy:settings file="stratus-ivysettings.xml" /> <ivy:resolve conf="test" file="stratus-ivy.xml"/> </target> Following is the excerpt from stratus-ivysettings.xml <resolvers <!-- here you define your file in private machine not on the repo (e.g. jPricer.jar or edgApi.jar)-- <!-- This we will use a url nd not local file system.. -- <url name="privateFS" <ivy pattern="http://xyz.svn.com/ivyRepository/ [organisation]/ivy/ivy.xml"/ </url . . . <url name="public" m2compatible="true" <artifact pattern="http://www.ibiblio.org/maven2/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]"/ </url . . . So as can be seen here for getting ivy.xml, I don’t need any proxy as its within our own network which cant be accesses when I set proxy. But on the other hand I am using ibiblio as well which is external to our network and works only with proxy. So above build.xml wont work in that case. Can somebody help here. I don’t need proxy while getting ivy.xml (as if I have proxy, ivy wont be able to find ivy file behind proxy from within the network), and I just need it when my resolver goes to public url.

  • ItemsPanel vs Grid vs GridSplitter

    - by bitbonk
    I am currently trying to build a ControlTemplate for an ItemsControl that uses the Grid as its ItemsPanel where each item is stacked horizontally and delimited with a GridSplitter. The basic goal is to have a dynamic bindable ItemsControl where all items stack up in a row and where each item can be resized with a splitter. There are two things I can't wrap my head around: How is the GridSplitter supposed to end up automatically between each item? How do I set Grid.Column for each item.
