  • Multi-Threading Question Concerning WPF

    - by Andrew
    Hello, I'm a newbie to threading, and I don't really know how to code a particular task. I would like to handle a mouse click event on a window that will kick off a while loop in a seperate thread. This thread, which is distinct from the UI thread, should call a function in the while loop which updates a label on the window being serviced by the UI thread. The while loop should stop running when the left mouse button is no longer being pressed. All the loop does is increment a counter, and then repeatedly call the function which displays the updated value in the window. The code for the window and all of the threading is given below (I keep getting some error about STA threading, but don't know where to put the attribute). Also, I'm hoping to use this solution, if it ever works, in another project that makes asynchronous calls elsewhere to a service via wcf, so I was hoping not to make any application-wide special configurations, since I'm really new to multi-threading and am quite worried about breaking other code in a larger program... Here's what I have: <Window x:Class="WpfApplication2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication2" Name="MyMainWindow" Title="MainWindow" Width="200" Height="150" PreviewMouseLeftButtonDown="MyMainWindow_PreviewMouseLeftButtonDown"> <Label Height="28" Name="CounterLbl" /> </Window> And here's the code-behind: using System.Windows; using System.Windows.Input; using System.Threading; namespace WpfApplication2 { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { private int counter = 0; public MainWindow() { InitializeComponent(); } private delegate void EmptyDelegate(); private void MyMainWindow_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e) { Thread counterThread = new Thread(new ThreadStart(MyThread)); counterThread.Start(); } private void MyThread() { while (Mouse.LeftButton == MouseButtonState.Pressed) { counter++; Dispatcher.Invoke(new EmptyDelegate(UpdateLabelContents), null); } } private void UpdateLabelContents() { CounterLbl.Content = counter.ToString(); } } } Anyways, multi-threading is really new to me, and I don't have any experience implementing it, so any thoughts or suggestions are welcome! Thanks, Andrew

  • Using google maps API, how can we set the current location as the default set location using map.set

    - by vs1984
    I am writing Javascript code using Google maps API. map = new google.maps.Map2(document.getElementById("map_canvas")); map.setCenter(new google.maps.LatLng(37.4419, -122.1419), 13); The above code sets the default location of the map canvas to Palo Alto. How can we write the script in such a way that the setCenter function automatically points to the current location of the client?

This is my code: decimal trans = trackBar1.Value / 5000 this.Opacity = trans When I try to build it, I get this error: Cannot implicitly convert type 'decimal' to 'double' I tried making trans a double, but then the control doesn't work. This code worked fine for me in VB.NET. What do I need to do differently?

  • Multiheaded X.org with a single workspace-pool

    - by blauwblaatje
    I've got an idea for x.org/$randomwindowmanager in combination with a multiheaded setup, but I haven't figured out how it should work. Also I don't really know where to place the feature request. Now for the idea. I've been working with screen (wikipedia:GNU_Screen) for some years now. One thing I like about it, is the fact that I can get a multi-display mode (screen -x), so you can have multiple terminals all connected to the same screen. The fun thing about it, is that you can get 2 terminals with the same content and switch my onscreen layout, without moving the terminals. I admit, in screen it's not extremely useful, but I think for a wm it can be. Imagine this. You've got two monitors and 4 workdesks. On one workdesk I've got my IDE with code, on the second one I've got the output, on the third one I've got the documentation and on the forth one I've got my e-mail and IM clients. At one moment, I want my IDE and output on my monitors, another moment my code and documentation and Yet another moment my IM to consult a colleague and documentation or code. Finally my colleague comes to help me at my desk. I'd like it if we could both watch the same workdesk without him sitting on my lap, so I turn one monitor so he can see it better. It would be great if we could see the same thing that's on my monitor (exclude mousepointer). The thing with most WMs is that your workspaces on the two monitors are either separated or glued together. If they're separated, you can change workspaces on each monitor autonomous, but you can't exchange applications between monitors because they're different x-clients (iirc). If they're glued together (xinerama), you can exchange the applications, but when changing your workspace, the other monitors change too. So, what I'd like to know is this. Is this already possible or should I submit a feature request somewhere (and if so, where?)

  • How to strip specific contents of a String in Java

    - by user2974877
    So I have a string, and I want to strip out some parts of it using, for example, the firt and last characters of the "interesting" part. String dirty = "$!$!%!%$something interesting&!!$!%$something interesting2"; And the output something like: String clean = "something interesting:something interesting2"; Note: The code needs to work without knowing the random part, changing everytime the program runs. I researched and only found code that does it, but only knowing the random segment.

  • Writing a Python extension in Go (golang)

    - by tehwalrus
    I currently use Cython to link C and Python, and get speedup in slow bits of python code. However, I'd like to use go routines to implement a really slow (and very parallelizable) bit of code, but it must be callable from python. (I've already seen this question) I'm (sort of) happy to go via C (or Cython) to set up data structures etc if necessary, but avoiding this extra layer would be good from a bug fix/avoidance point of view. What is the simplest way to do this without having to reinvent any wheels?

  • How to implement a tagging plugin for jQuery

    - by anxiety
    Goal: To implement a jQuery plugin for my rails app (or write one myself, if necessary) that creates a "box" around text after a delimiter is typed. Example: With tagging on SO, the user begins typing a tag, then selects one from the drop-down list provided. The input field recognizes that a tag has been selected, puts a space and then is ready for the next tag. Similarly, I am attempting to use this plugin to put a box around the previously entered tag before moving to to accept the next tag/input. The instructions in the README.txt seem simple enough, however I have been receiving a $(".tagbox").tagbox is not a function error when debugging my app with firebug. Here is what I have in my application.js: $(document).ready( function(){ $('.tagbox').tagbox({ separator: /\[,]/, // specifying comma separation for <code>tags</code> }); }); And here is my _form.html.erb: <% form_for @tag do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= text_field :tag, :name, { :method => :get, :class => "tagbox" } %> </p> <p><%= f.submit "Submit" %></p> <% end %> I have omitted some other code (namely the implementation of an autocomplete plugin) existing within my _form.html.erb and application.js for sake of readability. The inclusion or exclusion of this omitted code does not affect the performance of this plugin. I have included all of the necessary files for the tagbox plugin (as well as application.js after all other included JS files) within the javascript_include_tag in my application.html.erb file. I'm pretty much confused as to why I'd be getting this "not a function" error when jquery.tagbox.js clearly defines the function and is included in the head of my html page in question. I've been struggling with this plugin for longer than I'd like to admit, so any help would really be appreciated. And, of course, I'm open to any other plugins or from-scratch suggestions you may have in mind.. This tagbox plugin does not seem to have a wealth of documentation or any currently working examples. Also to note, I'm trying to avoid using jrails. Thanks for your time

  • jQuery: modify href attribute for first level list only

    - by bloggerious
    I'm a noob in jQuery and have stuck at this. I have the following HTML code output from a PHP page: <ul class="cats"> <li><span><a href="cant_post_link_yet1">Lifestyle</a></span></li> <li><span><a href="cant_post_link_yet2">Entertainment</a></span></li> <li class="has_child"> <span><a href="cant_post_link_yet3">Technology</a></span> <ul class="subcats"> <li><span><a href="cant_post_link_yet4">Gadgets</a></span></li> <li><span><a href="cant_post_link_yet5">Hardware</a></span></li> </ul> </li> <li><span><a href="cant_post_link_yetsports">Sports</a></span></li> <li class="has_child"> <span><a href="cant_post_link_yet6">Design</a></span> <ul class="subcats"> <li class="has_child"> <span><a href="cant_post_link_yet7">Web Design</a></span> <ul class="subcat"> <li><span><a href="cant_post_link_yet8">Adobe Photoshop</a></span></li> </ul> </li> <li><span><a href="cant_post_link_yet9">Graphics and Print</a></span></li> </ul> </li> What's the correct jQuery code so that I can modify the href attribute for the first-level list only? Basically, I want to change the href of Technology and Design to be "#" but will not change the href of Web Design which is already on second-level list. More Info: In the code above, if list has subcategories, then it has the class has_child, whether it's on first-level or not. So I want only the first-level list which has class has_child to be modified the href to "#" I can't alter output anymore because it's in the PHP code. Any help is greatly appreciated.
