  • Can piping of screen 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 piping the screen 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 output three variables that are computed initially, and that's what I get with and without piping direct to screen: 0 -0.02 0 piped: 0 -0.02 1.04083e-17 So there's a round-off difference with and without piping the output! Now, why piping would interefere with an internal computation of the code?

  • Is there a better way to change user password in cakephp using Auth?

    - by sipiatti
    Hi, I am learning cakephp by myself. I tried to create a user controller with a changepassword function. It works, but I am not sure if this is the best way, and I could not googled up useful tutorials on this. Here is my code: class UsersController extends AppController { var $name = 'Users'; function login() { } function logout() { $this->redirect($this->Auth->logout()); } function changepassword() { $session=$this->Session->read(); $id=$session['Auth']['User']['id']; $user=$this->User->find('first',array('conditions' => array('id' => $id))); $this->set('user',$user); if (!empty($this->data)) { if ($this->Auth->password($this->data['User']['password'])==$user['User']['password']) { if ($this->data['User']['passwordn']==$this->data['User']['password2']) { // Passwords match, continue processing $data=$this->data; $this->data=$user; $this->data['User']['password']=$this->Auth->password($data['User']['passwordn']); $this->User->id=$id; $this->User->save($this->data); $this->Session->setFlash('Password changed.'); $this->redirect(array('controller'=>'Toners','action' => 'index')); } else { $this->Session->setFlash('New passwords differ.'); } } else { $this->Session->setFlash('Typed passwords did not match.'); } } } } password is the old password, passwordn is the new one, password2 is the new one retyped. Is there any other, more coomon way to do it in cake?

  • How can I change my code in Excel 2003 to allow me to paste to multiple cells?

    - by PikeCoAL
    Ran in to a little problem. If I try to paste to multiple cells that are in the range in the code below, I get a run time error 13, type mismatch. The cells in the range may have data other than X but I only want the hyperlink to appear if the cell contains X. It works fine if I just type an X in the cell or if I paste to one cell at a time. I will have times when I want to paste other text to mutiple cells in this range. Thanks to Remnant for his help on the original code. This one last hurdle will put me in the clear. Thx. Private Sub Worksheet_Change(ByVal Target As Range) Dim rangeLimit As Range Set rangeLimit = Range ("B9:B37,C9:C37,D9:D37,E9:E37,F9:F37,G9:G37,H9:H37,I9:I37,J9:J37,K9:K37,L9:L37,M9:M37") If Not Intersect(rangeLimit, Target) Is Nothing Then If Target = "x" Or Target = "X" Then Target.Hyperlinks.Add Anchor:=Target, Address:="", SubAddress:="Exceptions!A1", TextToDisplay:=Target.Value End If End If End Sub

  • How can I change standart input/output of another program?

    - by Azad Salahli
    I have a console application written in c++. It simply reads an integer from standard input(keyboard) and writes another integer to standard output(screen). Now I want to give some tests to that program and check its answers using another program. In another words, I want to write electron judge for that program. I want that program(which I want to test) to read from file and write to file without changing source code. How can I do that. I tried assigning input&output to files before executing c++ program, but it did not worked. assign(input,'temp.in'); reset(input); assign(output,'temp.out'); rewrite(output); exec('domino.exe'); close(input); close(output);

    - by IronGoofy
    I've set up a simple jQueryUI progressbar: <script type="text/javascript"> $(function() { $("#progressbar").progressbar({ value: 35 }); }); </script> <div id="progressbar"> </div> Now, I'd like to color the of the bar based on it's value (e.g. <10 red, <50 yellow, 50 green). How do I do this? Note: There are similar questions, but the answers were not clear enough to help me get things done. Hopefully, someone can point out an easier way or provide more detailed instructions. Thanks.

  • 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).

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.

  • [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 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!

  • 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?

  • 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 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 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 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?
