  • Why is my html getting mal-formed?

    - by alkaloids
    I have the following table in a form that's embedded in a formtastic form (semantic_form_for). Everything I ask to be generated by ruby shows up, but the table gets badly mangled (essentially, the tags NEVER get formed. The table headers get drawn correctly There are 14 available_date objects that get passed, and they alternate between having a time value of 1 or 2, so this is just terribly boggling, but probably simple to fix... <table class="availability_table"> <tr> <th>Date</th> <th>Early</th> <th>Late</th> </tr> <% f.fields_for :available_dates do |ad| %> <% if ad.object.time == 1 #if this is an early shift, then start the new row %> <tr><td><%= ad.object.date.strftime('%a, %b %d, %Y') %></td> <td><%= ad.collection_select(:availability , LookupAvailability.all.collect, :id, :name) %></td> <% else #otherwise end the row with just a box%> <td><%= ad.collection_select(:availability , LookupAvailability.all.collect, :id, :name) %></td></tr> <% end %> <% end %> </table> So like I said, the form functions properly, and the objects all get updated and displayed correctly and all that, it's just that the HTML isn't getting echo'd out properly so my table is all mangled. Help!

  • WPF- Why can't my custom textbox be selected?

    - by highone
    I have this custom textbox that I am working on and I can use it in xaml, but when I run my app I cannot select it or type in it. Here is my code: public class ModdedTextBox : TextBox { private bool selectionStartChangeFromUI; private bool selectionLengthChangeFromUI; private bool selectedTextChangeFromUI; static ModdedTextBox() { DefaultStyleKeyProperty.OverrideMetadata(typeof(ModdedTextBox), new FrameworkPropertyMetadata(typeof(ModdedTextBox))); //this.SelectionChanged += this.OnSelectionChanged; //PropertyDescriptor VerticalOffsetProperty = TypeDescriptor.GetProperties(typeof(ModdedTextBox))["VerticalOffset"]; //VerticalOffsetProperty.AddValueChanged(this, this.OnVerticalOffsetChanged); } public static readonly DependencyProperty BindableSelectionStartProperty = DependencyProperty.Register( "BindableSelectionStart", typeof(int), typeof(ModdedTextBox), new PropertyMetadata(OnBindableSelectionStartChanged)); public static readonly DependencyProperty BindableSelectionLengthProperty = DependencyProperty.Register( "BindableSelectionLength", typeof(int), typeof(ModdedTextBox), new PropertyMetadata(OnBindableSelectionLengthChanged)); public static readonly DependencyProperty BindableSelectedTextProperty = DependencyProperty.Register( "BindableSelectedText", typeof(string), typeof(ModdedTextBox), new PropertyMetadata(OnBindableSelectedTextChanged)); public static readonly DependencyProperty DelayedTextProperty = DependencyProperty.Register( "DelayedText", typeof(string), typeof(ModdedTextBox), new PropertyMetadata(OnDelayedTextChanged)); public int BindableSelectionStart { get { return (int)this.GetValue(BindableSelectionStartProperty); } set { this.SetValue(BindableSelectionStartProperty, value); } } public int BindableSelectionLength { get { return (int)this.GetValue(BindableSelectionLengthProperty); } set { this.SetValue(BindableSelectionLengthProperty, value); } } public string BindableSelectedText { get { return (string)this.GetValue(BindableSelectedTextProperty); } private set { this.SetValue(BindableSelectedTextProperty, value); } } public string DelayedText { get { return (string)this.GetValue(DelayedTextProperty); } private set { this.SetValue(DelayedTextProperty, value); } } private static void OnBindableSelectionStartChanged(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs args) { var textBox = dependencyObject as ModdedTextBox; if (!textBox.selectionStartChangeFromUI) { int newValue = (int)args.NewValue; textBox.SelectionStart = newValue; } else { textBox.selectionStartChangeFromUI = false; } } private static void OnBindableSelectionLengthChanged(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs args) { var textBox = dependencyObject as ModdedTextBox; if (!textBox.selectionLengthChangeFromUI) { int newValue = (int)args.NewValue; textBox.SelectionLength = newValue; } else { textBox.selectionLengthChangeFromUI = false; } } private static void OnBindableSelectedTextChanged(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs args) { var textBox = dependencyObject as ModdedTextBox; if (!textBox.selectedTextChangeFromUI) { string newValue = (string)args.NewValue; textBox.BindableSelectedText = newValue; } else { textBox.selectedTextChangeFromUI = false; } } private static void OnDelayedTextChanged(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs args) { } private void OnSelectionChanged(object sender, RoutedEventArgs e) { if (this.BindableSelectionStart != this.SelectionStart) { this.selectionStartChangeFromUI = true; this.BindableSelectionStart = this.SelectionStart; } if (this.BindableSelectionLength != this.SelectionLength) { this.selectionLengthChangeFromUI = true; this.BindableSelectionLength = this.SelectionLength; } if (this.BindableSelectedText != this.SelectedText) { this.selectedTextChangeFromUI = true; this.BindableSelectedText = this.SelectedText; } } private void OnVerticalOffsetChanged(object sender, EventArgs e) { MessageBox.Show("hello the vertical offset works"); } }

  • why is my 3n+1 problem solution wrong?

    - by nunos
    I have recently started reading "Programming Challenges" book by S. Skiena and believe or not I am kind of stuck in the very first problem. Here's a link to the problem: 3n+1 problem Here's my code: #include <iostream> #include <vector> #include <algorithm> using namespace std; unsigned long calc(unsigned long n); int main() { int i, j, a, b, m; vector<int> temp; while (true) { cin >> i >> j; if (cin.fail()) break; if (i < j) { a = i; b = j; } else { a = j; b = i; } temp.clear(); for (unsigned int k = a; k != b; k++) { temp.push_back(calc(k)); } m = *max_element(temp.begin(), temp.end()); cout << i << ' ' << j << ' ' << m << endl; } } unsigned long calc(unsigned long n) { unsigned long ret = 1; while (n != 1) { if (n % 2 == 0) n = n/2; else n = 3*n + 1; ret++; } return ret; } I know the code is inefficient and I should not be using vectors to store the data. Anyway, I still would like to know what it's wrong with this, since, for me, it makes perfect sense, even though I am getting WA (wrong answer at programming challenges judge and RE (Runtime Error) at UVa judge). Thanks.

  • Why use ASP.NET MVC 2 for REST services? Why not WCF?

    - by Jeremy McGee
    So I see that MVC 2 now supports [HttpPut] and [HttpDelete] as well as [HttpGet] and [HttpPost], making it possible to do a full RESTful Web service using it. I've been using the REST toolkit for WCF for a while and find it fairly powerful, but I'd be interested to find out what (if any) advantages there are using the MVC 2 approach. Links, war stories, or even pure hear-say are welcome.

  • why can't I comment lines in visual mode

    - by Haiyuan Zhang
    I want to comment several lines in my .vimrc, the usual way I do it is :x,ys/^/"/ and x stands for the start line number and y stands for the line number of the last line. I read some post which said in visual mode this task can be done by the following step: 1 Select your lines with VISUAL BLOCK 2 press I to insert before all highlighted lines. 3 type your comment charact , in this case should be " 4 then ESC I fllowed the above steps and met met problems in step 2 . the thing is when I select the lines in Visual mode and press I , vim ( I use version7.2) go back to insert mode and the cursor back to the start of the first line. so if you continue to do the step 3 and step 4, you end up in just inserting " at the start the first line , far from what I want to achieve. so could you point out what's wrong with the recipe ? thanks in advance

  • Why did this work? ( php dot notation )

    - by Daniel
    Hi, I was writing some php code after a long sint doing ruby and I accidently wrote this: [root@ip-10-160-47-98 test]# cat run.php <?php class MyTest { public function run() { var_dump(this.test); } } $object = new MyTest(); $object->run(); [root@ip-10-160-47-98 test]# php run.php string(8) "thistest" [root@ip-10-160-47-98 test]# Now, this.test should have been $this-test, but the compiler was actually happy to let this run. Does anyone know how (this.test) got converted into a string "thistest"? Compiled and run on php 5.3.2 amazon instance ami-e32273a6 (CentOS 5.4) -daniel

  • Why use Oracle Application Express for web app?

    - by Jack
    Hi all. I believe we're moving to Oracle Apex for future development. I've read about Oracle Apex on wikipedia and it's pro and con. It seem to me the con outweigh the pro but maybe I'm wrong. I get the sense that Oracle Apex is for DBA with little or no programing knowledge to setup a web app quickly sort like MS Access for none programmer. If you have Oracle Apex working experience, can you share your though? From wikipedia's entry, it doesn't seem like you need to know any programming language at all but just the PL/SQL? edit: Is Oracle Apex scalable? Can it handle traffic like Facebook's size? Thank. Jack

  • Why does multiplying a double by -1 not give the negative of the current answer

    - by Ankur
    I am trying to multiply a double value by -1 to get the negative value. It continues to give me a positive value double man = Double.parseDouble(mantissa); double exp; if(sign.equals("plus")){ exp = Double.parseDouble(exponent); } else { exp = Double.parseDouble(exponent); exp = exp*-1; } System.out.println(man+" - "+sign+" - "+exp); The printed result is 13.93 - minus - 2.0 which is correct except that 2.0 should be -2.0

  • Why isn't JML implemented as Annotations in Java?

    - by devoured elysium
    Contrary to Code Contracts in C#, in JML Code Contracts are just text that's used in the form of comments in the header of a method. Wouldn't it be better to have them exposed as Annotations, then? That way even when compiling the information would persist on the .class's metadata, contrary to comments, that get erased. Am I missing something? Thanks

  • Why are my CATransitions acting up?

    - by Regan
    I am using the following code to switch between views with CATransition. CATransition *applicationLoadViewIn = [CATransition animation]; [applicationLoadViewIn setDuration:20]; [applicationLoadViewIn setType:kCATransitionPush]; [applicationLoadViewIn setSubtype:kCATransitionFromTop]; [applicationLoadViewIn setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]]; ViewToSwitchTo *myviewcontroller = [[ViewToSwitchTo alloc] init]; [self.view.layer addAnimation:applicationLoadViewIn forKey:kCATransitionPush]; [self.view addSubview:myviewcontroller.view]; It functions mostly how I want it to. It pushes from the top like it should, however it for some reason acts strangely. First, the view I am switching to starts coming in from the bottom like it should, but for some reason, the view that I am switching FROM appears over the top of it with low opacity, so you see both of them. However, you also see the view that is coming in, shifted maybe 100 pixels upwards, on top of itself and the other view, once again with low opacity. Just before the halfway point of the the transition, everything works fine, you only see the view that is coming in and the view going out, doing what they should be doing. But slightly after the halfway point, the view I am switching to appears in its final destination, under the view I am switching from, and the view I am switching from has been reduced in opacity. What is going on here?

  • Why doesn't javascript function aliasing work?

    I have some Firebug console function calls that I wanted to disable when Firebug wasn't enabled, e.g. console isn't defined.

  • Graphics.FromHwnd(IntPtr.Zero) returns null, why?

    - by Martin Moser
    I'm currently investigating a problem with a 3rd party component (DevExpress) in my application. My issue is quite similar to this one DevExpress KB article. I get the same exception with more less the same stacktrace. So I used .NET Reflector to find out, what may be null in this scenario, and the only object which is a candiate to be null is Graphics. This is created with Graphics.FromHwnd(IntPtr.Zero). Because I don't have a broad knowledge about GDI, I would like to know if somebody can tell me possible scenarios when this may return null... I tried to reproduce it in a scenario where windows is out of GDI handle's, but then I'm getting a "out of handles" - exception at least once, which is not the case in the issue I'm investigating tia, Martin

  • Why does TabStop stop working??

    - by Jerry
    I have a project that uses a series of auto-generated user control instances. The user-control itself exists, but I populate a panel with a series of these user controls, one for each item in my collection. Each user control displays a ton of information, but only ONE text field is editable. All of the other fields have TabStop set to false, and are marked as ReadOnly. The tab order of each user control is set at the time it is created so that the tab-key goes from one field to the next (or ... it's supposed to). When I have TWO fields on my user control whose TabStop is set to true, everything works great. But if I only have ONE field whose TabStop is true, the tab key stops working, and I have to physically CLICK on the next user control for it to gain focus. What's up? Has anyone else seen this behavior? Am I doing something stupid as usual?
