  • Can redirection of screen output to file change the result of a C++ code?

    - by Biga
    I am having this very weird behaviour with a C++ code: It gives me different results when running with and without redirecting the screen output to a file (reproducible in cygwin and linux). I mean, if I get the same executable and run it like ./run or run it like ./run >out.log, I get different results! I use std::cout to output to screen, all lines ending with endl; I use ifstream for the input file; I use ofstream for output, all lines ending with endl. I am using g++ 4. Any idea what is going on? UPDATE: I have hard-coded the input data, so 'ifstream' is not used, and problem persists. UPDATE 2: That's getting interesting. I have probed three variables that are computed initially, and that's what I get when using with and without redirecting the output to file redirected to file: 0 -0.02 0 direct to screen: 0 -0.02 1.04083e-17 So there's a round-off difference in the code variables with and without redirecting the output! Now, why redirecting would interefere with an internal computation of the code? UPDATE 3: If I redirect to /dev/null, I get the sam behaviour as outputing direct to screen, instead of redirecting to file.

  • How to change the width of displayed text nested in a div?

    - by romaintaz
    Hello, Imagine I have the following code (simplified regarding my real context of course): <div id="box" style="width: 120px;" onmouseover="this.style.width='200px'" onmouseout="this.style.width='120px'"> <div>A label</div> <div>Another label</div> <div>Another label, but a longer label</div> </div> What I want to achieve is the following: My div box has a fixed width (120px by default). In this configuration, every label nested in the box must be written in a single line. If the text is too long, then the overflow must be hidden. In my example, the third item will be displayed Another label, but a or Another label, but a .... When the cursor is entering the div box, the width of the box is modified (for example to 200px). In this configuration, the labels that were shorten in the first configuration are now displayed in the whole space. With my code snippet, the third label is displayed in two lines when the box has a 120px, and I do not want that... How can I achieve that? Note that I would be great if the solution works also for IE6! Even if I prefer a pure CSS/HTML solution, (simple) Javascript (and jQuery) is allowed!

  • [Ruby] Modifying object inside a loop doesn't change object outside of the loop?

    - by Jergason
    I am having problems with modifying objects inside blocks and not getting the expected values outside the blocks. This chunk of code is supposed to transform a bunch of points in 3d space, calculate a score (the rmsd or root mean squared deviation), and store both the score and the set of points that produced that score if it is lower than the current lowest score. At the end, I want to print out the best bunch of points. first = get_transformed_points(ARGV[0]) second = get_transformed_points(ARGV[1]) best_rmsd = first.rmsd(second) best_points = second #transform the points around x, y, and z and get the rmsd. If the new points # have a smaller rmsd, store them. ROTATION = 30 #rotate by ROTATION degrees num_rotations = 360/ROTATION radians = ROTATION * (Math::PI/180) num_rotations.times do |i| second = second * x_rotate num_rotations.times do |j| second = second * y_rotate num_rotations.times do |k| second = second * z_rotate rmsd = first.rmsd(second) if rmsd < best_rmsd then best_points = second best_rmsd = rmsd end end end end File.open("#{ARGV[1]}.out", "w") {|f| f.write(best_points.to_s)} I can print out the points that are getting stored inside the block, and they are getting transformed and stored correctly. However, when I write out the points to a file at the end, they are the same as the initial set of points. Somehow the best_points = second chunk doesn't seem to be doing anything outside of the block. It seems like there are some scoping rules that I don't understand here. I had thought that since I declared and defined best_points above, outside of the blocks, that it would be updated inside the blocks. However, it seems that when the blocks end, it somehow reverts back to the original value. Any ideas how to fix this? Is this a problem with blocks specifically?

  • How can I inherit an ASP.NET MVC controller and change only the view?

    - by AlexWalker
    I have a controller that's inheriting from a base controller, and I'm wondering how I can utilize all of the logic from the base controller, but return a different view than the base controller uses. The base controller populates a model object and passes that model object to its view, but I'm not sure how I can access that model object in the child controller so that I can pass it to the child controller's view.

  • How do I change the visual style of a listitem based on its bound value?

    - by Rodd
    I have a listbox (here's the xaml): <ListBox MinWidth="300" ItemsSource="{Binding Relationships, Mode=OneWay}" SelectedItem="{Binding SelectedRelationship, Mode=TwoWay}" SelectionMode="Single" HorizontalAlignment="Left" > <ListBox.ItemTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <CheckBox IsChecked = "{Binding IsPrimary}" IsHitTestVisible="False" /> <StackPanel Orientation="Horizontal" Grid.Column="1"> <TextBlock Text="{Binding RelationshipType}" FontWeight="Bold" Margin="0,0,5,0" /> <TextBlock Text="{Binding Status}" FontStyle="Italic" /> </StackPanel> <TextBlock Text="{Binding UnitName}" Grid.Row="1" Grid.Column="1" /> <TextBlock Text="{Binding StartDate, Converter={StaticResource DateConverter}}" Grid.Row="2" Grid.Column="1"/> <TextBlock Text="{Binding RetireDate}" Grid.Row="3" Grid.Column="1" /> <TextBlock Text="{Binding EndDate}" Grid.Row="4" Grid.Column="1" /> <TextBlock Text="{Binding ReasonForLeaving}" Grid.Row="5" Grid.Column="1" /> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> What I want to do is have each item in the listbox have one of 3 backgrounds (green if the value of IsPrimary = true, Orange if the EndDate value is empty and grey if the EndDate value is not empty. Is there a way to template the listbox items so that they evaluate bound items to determine a view state or to have each listbox item bind to a value that I can set for each item in my viewmodel? Thanks for your help.

  • How can I change my JLabel to look like a table cell with Substance?

    - by DR
    I have a custom TableCellRenderer which returns a JLabel as the renderer component. Naturally the table cell now looks like a label and no longer like a table cell, which makes a difference especially when using Substance. Is it possible to modify the label so that the LaF renders it like an ordinary table cell? The best I could do was setting the background color of the label, but the borders and transition effets are missing.

  • How to change aif to be able to access 'it' within the macrocall without making 'it' public in the package

    - by Sim
    If you put the aif code presented in onlisp in a package and try to use it in another you run in the problem that packagename:it is not external. (in-package :packagename) (defmacro aif (test-form then-form &optional else-form) ‘(let ((it ,test-form)) (if it ,then-form ,else-form))) wanted call syntax (in-package :otherpackage) (aif (do-stuff) (FORMAT t "~a~%" it) (FORMAT t "just got nil~%")) How can I fix this behavior in code, without making the variable it external in the package declaration and beeing able to access it just by it instead of packagename:it?

  • How to mutibind three properties, to dispatch the last change to all properties?

    - by WPFadvocate
    In WPF, I've three objects exposing the same DependencyProperty (let's say it's an integer). I want all three property values to remain synchronized, i.e. that whenever the int value changes in an object, this value is propagated to the two other objects. I think of multibinding to do the job, but I don't know how to detect which object changed, thus which value should be used and propagated to the other objects.

  • How to change CSS style of nested list items?

    - by Yasir
    I have a style for styling <a> elements in list items in a #navigation container. This is working fine. #navigation li a { text-decoration:none; background:#bfe5ff; color:#045e9f; width:125px; height:35px; padding-top:11px; display:block; float:left; margin-left:2px; text-align:center; font-size:18px; font-weight:bold; } Now in some <li>s I am inserting <div>s. In these I am again using a list again, but it should be different in style or have no style. When I put in <li>s, their style matches the outer <li> elements, but it should not. I am trying to use this: #newnavigation li a { font-size:12px; margin-left:20px; } but it's not working - it applies the "outer" styles. This is my markup: <ul id="navigation"> <li><a href="index.html">Home</a></li> <li><a href="about.html">About</a></li> <li><a href="contact.html">Contact</a></li> <li class="browse"> <a href="#">Browse</a> <div id="browsecontainer"> <h3>Browse By Category</h3> <li><a href="#"></a></li> </div> </li> </ul>

  • Quantifying the amount of change in a git diff?

    - by Alex Feinman
    I use git for a slightly unusual purpose--it stores my text as I write fiction. (I know, I know...geeky.) I am trying to keep track of productivity, and want to measure the degree of difference between subsequent commits. The writer's proxy for "work" is "words written", at least during the creation stage. I can't use straight word count as it ignores editing and compression, both vital parts of writing. I think I want to track: (words added)+(words removed) which will double-count (words changed), but I'm okay with that. It'd be great to type some magic incantation and have git report this distance metric for any two revisions. However, git diffs are patches, which show entire lines even if you've only twiddled one character on the line; I don't want that, especially since my 'lines' are paragraphs. Ideally I'd even be able to specify what I mean by "word" (though \W+ would probably be acceptable). Is there a flag to git-diff to give diffs on a word-by-word basis? Alternately, is there a solution using standard command-line tools to compute the metric above?

  • XAML : How to change background color only in Design mode?

    - by Kave
    I have a control with white text foreground color and transparent background color. Later on this usercontrol will be added into a different control that carries the real background color. However during designing this, control due white foreground on white background in VS 2010, I can't obviously see anything. In there anyway to define a different color for just the design time? I have tried this: if (System.ComponentModel.DesignerProperties.IsInDesignTool) { LayoutRoot.Background = new SolidColorBrush(Colors.Blue); } But this doesn't work. Any tips? Thanks, Kave

  • Ushahidi - How to make the markers stay on the map on zoom change?

    - by Guttemberg
    I am using the platform Ushahidi Web-2.7.3 , see: http://ti5.net.br/provedorlegal.com.br, and when I zoom in beyond a certain level, the clustered markers disappear from the map. I also tested this on an older version of a site, see: http://movimentofichalimpa.org/mapa, where the clustered markers do not disappear on zooming in, but just become ungrouped, as is normal with a cluster strategy. How can I make the markers remain on the map when zooming in?
