  • How can I drag and drop a xaml activity to a WF4 rehosted designer?

    - by Louis Rhys
    I understand that the WorkflowDesigner can receive a dragged item in several ways, for example: By dragging an item from the toolbox and dropping it on the designer: an empty activity of that type will be inserted on the designer at the drop location. One can also drag an activity from the designer and drop it on another location in the designer, the dragged activity will be inserted at the drop location as well. Is it possible that similar to these two drag and drop mechanism, I can drag a xaml activity to the designer? What I have in mind is this, Let's say you have a ListView containing several xaml files. I want to be able to drag one of the ListView items (ie one of the xaml files), and when I drag it over the designer it will act as if I drag something from the toolbox (except the activity will be supplied from the xaml). I know I can create a runtime Activity from the file by using ActivityXamlServices.Load(filename), and I want this activity to be inserted at the drop location. But how to tell the application to understand this when I drag and drop?

  • WPF Show Open TabItem Names in a List View

    - by mr justinator
    I'm trying to display a list of open tab names in a listview or listbox (recommendations?). Been going through the different type of binding options and I'm able to bind to a single tab name but it displays vertical instead of horizontal. Here is my XAML: <ListView DockPanel.Dock="Left" Height="352" Name="listView1" Width="132" ItemsSource="{Binding ElementName=RulesTab, Path=Name}" IsSynchronizedWithCurrentItem="True" FlowDirection="LeftToRight" HorizontalAlignment="Left" HorizontalContentAlignment="Left" DataContext="{Binding}"> Any pointers would be greatly appreciated as I'd like to be able to see a list of all the tabs open and then double click on one to bring the tab into focus. Many thanks!

  • ruby/ruby on rails memory leak detection

    - by Josh Moore
    I wrote a small web app using ruby on rails, its main purpose is to upload, store, and display results from xml(files can be up to several MB) files. After running for about 2 months I noticed that the mongrel process was using about 4GB of memory. I did some research on debugging ruby memory leaks and could not find much. So I have two questions. Are there any good tools that can be used to find memory leaks in Ruby/rails? What type of coding patterns cause memory leaks in ruby?

  • exe files and Python

    - by Sorush Rabiee
    i have some questions about python: 1- How to build .exe files from .py files? 2- How to run a program with arguments and receive the result by python code? 3- How to load .NET library in python code (or write python in VS.NET IDE [!?])? 4- is built-in integer of python 3.1 something like a string? it calculates 200! in less than one second and calculates 2^1 to 2^7036 (by a simple recursive algorithm & writing them to a text file) with a 1.75GHz cpu in 4 minuets, so if it is a string, how it can be so fast like this? is there a great difference between memory type and logical calculation of python with c++? 5- what is the best python practice? how can i be an expert?

  • Problem creating site using Microsoft Visual Web Developer Express 2008

    - by Peter
    Hi, this is a very newbie question, sorry! I need to create an aspx website based con C# and am calling some webservices based on some DLL's I already have. Beforem purchasing Visual Studio, I decided to try Microsoft Visual Web Developer Express (is this ok?) creating a Web Application ASP.NET based on Visual C#. I created the form to enter the data which is submitted when clicking the process button. At this point I need to call stuff from the DLL, which I have added in the Solution Explorer via Add Reference, selecting the DLL from the COM list. But whenever I run the project, I always get the error "the type or namespace xxx cannot be found - maybe a using directive or assembler directive is missing" when trying to create the object. What is my stupid mistake? Thanks!

  • 2 questions about drag and drop with Javascript

    - by David
    Hello, I'm trying to be able to drag random highlighted text or images on a random page that is not written by me, thus I cannot simply wrap the text in a div and make it draggable. Is there any way to get highlighted text or images on a random page, like say Yahoo, and drop it into a container that can recognize what was being dropped into it (like content and content-type) without it even being an explicitly declared draggable? I've been playing with jQuery, but can't figure it out. Any help would be greatly appreciated. Regards, David

  • Join map and refer to its key/value in HQL

    - by alamar
    Suppose I have a map: <map name="externalIds" table="album_external_ids"> <key column="album_id" not-null="true"/> <map-key-many-to-many class="Major" column="major_id"/> <element column="external_id" type="string" not-null="true"/> </map> How do I make a HQL meaning "select entities where map key's id == :foo and map value == :bar"? I can join it using select album from Album album join album.externalIds ids But how would I then refer to ids' key and value? ids.key.id = :foo and ids.value = :bar doesn't work, and hibernate doc is silent on this topic. Naive approaches that didn't work: select album from Album album join album.externalIds externalId where index(externalId).id = :foo and externalId = :bar and select album from Album album join album.externalIds externalId join index(externalId) major where major.id = :foo and externalId = :bar

  • CSS sprites navigation and User with image disabled.....

    - by metal-gear-solid
    I made a css menu with css sprites but the problem is with sprite we don't use inline image we use in background only so if images are disabled in browser then nothing will show . any solution for this ? For example : See this menu and turn off images : http://line25.com/wp-content/uploads/2009/css-menu/demo/demo.html (it will not be seen if images are disabled in browser) this menu is against on this quote Ensure your website works with images disabled Creating a site that relies too heavily on images is never a good idea. Although almost a thing of the past, there are still users who run at very low internet speeds. Also, if a user needs to—for whatever reason—disable images, can they still access all the content they need to? http://csswizardry.com/quick-tips/#tip-02 Shouldn't we use this type of navigation.

  • Using CSS Classes for indivdual effects - opinions?

    - by Cool Hand Luke UK
    Hey, Just trying to canvas some opinions here. I was wondering how people go about adding individual effects to html elements. Take this example: you have three types of h1 titles all the same size but some are black some are gold and some are white. Some have a text-shadow etc. Would you create separate CSS classes and add them do the h1 tag or would you create a new single class for each different h1 title type (with grouped CSS elements)? With singular class for each effect you can build up combos of classes in html class="gold shadow" but also how would you name them. For example its bad practice to give classes and id names associated to colours, because it doesn't define what it does well. However is this ok with textual CSS classes? Just wondering what others do, I know there are no hard and fast rules. Cheers.

  • How does Unity.Resolve know which constructor to use?

    - by stiank81
    Given a class with several constructors - how can I tell Resolve which constructor to use? Consider the following example class: public class Foo { public Foo() { } public Foo(IBar bar) { Bar = bar; } public Foo(string name, IBar bar) { Bar = bar; Name = name; } public IBar Bar { get; set; } public string Name { get; set; } } If I want to create an object of type Foo using Resolve how will Resolve know which constructor to use? And how can I tell it to use the right one? Let's say I have a container with an IBar registered - will it understand that it should favor the constructor taking IBar? And if I specify a string too - will it use the (string, IBar) constructor? Foo foo = unityContainer.Resolve<Foo>(); And please ignore the fact that it would probably be easier if the class just had a single constructor...

    - by schouk
    There is a strange behaviour with json_encode and json_decode and I can't find a solution: My php application calls a php web service.

  • Scope of variables inside anonymous functions in C#

    - by Vinod
    I have a doubt in scope of varibles inside anonymous functions in C#. Consider the program below: delegate void OtherDel(int x); public static void Main() { OtherDel del2; { int y = 4; del2 = delegate { Console.WriteLine("{0}", y);//Is y out of scope }; } del2(); } My VS2008 IDE gives the following errors: [Practice is a class inside namespace Practice] 1.error CS1643: Not all code paths return a value in anonymous method of type 'Practice.Practice.OtherDel' 2.error CS1593: Delegate 'OtherDel' does not take '0' arguments. It is told in a book: Illustrated C# 2008(Page 373) that the int variable y is inside the scope of del2 definition. Then why these errors.

  • null-coalescing operator or conditional operator

    Which coding style do you prefer: object o = new object(); //string s1 = o ?? "Tom"; // Cannot implicitly convert type 'object' to 'string' CS0266 string s3 = Convert.ToString(o ?? "Tom"); string s2 = (o != null) ? o.ToString() : "Tom"; s2 or s3? Is it possible to make it shorter? s1 does not obviously work.

  • iPhone "slide to unlock" animation

    - by Russ
    Any ideas as to how Apple implemented the "slide to unlock" (also, "slide to power off" is another identical example) animation? I thought about some sort of animating mask - but masking is not available on the iPhone OS for performance reasons. Is there some private API effect (like SuckEffect) that they might have used? A spotlight type of effect? Some Core Animation thing? Edit: It's definitely not a series of stills. I've seen examples of being edit a plist value or something and customize the string on jailbroken iphones.

  • MbUnit (gallio) and Visual Studio.Net Tests Not Completing or Debugging

    - by Davy
    Hi I'm using Gallio\MbUnit 3.1 with ReSharper and Visual Studio 2008. Everything is working well except this type of test: [Test] [Row("test@badEmail@_test.com")] [Row("test@badEmail@_test.")] public void IsValidEmail_Invalid_Emails_Should_Return_False(string invalidEmail) { Assert.IsFalse(AppHelper.IsValidEmail(invalidEmail), "Email validation failed for " + invalidEmail); } The test doesn't complete or go in to debug mode only when I pass in a parameter E.g. 'string invalidEmail'. If I remove that prameter it seems to work normally. It will run the test if I have: [Test] public void IsValidEmail_Invalid_Emails_Should_Return_False() { var invalidName = test@badEmail@_test.com"; Assert.IsFalse(AppHelper.IsValidEmail(invalidEmail), "Email validation failed for " + invalidEmail); } I appreciate that there may be better ways to achieve this test but I'm trying to work my way through a book and this is how it's explaining things. Any help is appreciated. Davy

  • Best online course for C#/SQL for a professional engineer

    - by Rich
    I know similar questions have been asked, but I've not been able to find information specific to my situation. I'm looking for "continuing education"-type options, specifically a C# and/or SQL course. I'm a software engineering professional with a graduate level computer science degree. So I'm looking for something substantial that will be challenging. I certainly already have me feet wet in both C# and SQL I'm just looking for a more formal training to round out the edges. There is a good chance my company will pay for it if it is reasonably priced so it doesn't have to be free and preferably shouldn't be (a certificate or certification to come out of it would be nice). When I tried Google, all I found were things that sounded like crash courses (like a 3 day course or course for "dummies"), or course that did not seem very credible. Can anyone recommend a course of action for this? Thanks!
