  • Why the data binding in this validation example works in WPF?

    - by MartyIX
    I'm wondering how exactly the XAML sample (MSDN sample) works: <Style x:Key="textBoxInError" TargetType="{x:Type TextBox}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> Questions: (Validation.Errors)[0].ErrorContent - Is this code somehow checked by WPF? Because Validation.Errors may be an empty collection and in ordinary C# code this code may throw an exception. If this data-binding returns null for valid input - the null value is then casted to empty string (in a text control for example)? The index 0 corresponds to the first error message. How can I return more error messages from Validate method? Thank you for responses!

  • Aliasing localhost in Tomcat

    - by Saurabh
    I have a web application "quicker" deployed in Tomcat5.5 version. Usually, I run this application by using url, localhost/quicker and it loads the index.jsp file which is the home page of application. I would like same application to be run using url, www.local.dev.mydomain.com/quicker. Would it be possible by doing some configuration in server.xml or some other place? One way of doing this is could be, modify hosts file in windows as - # 127.0.0.1 localhost 127.0.0.1 www.local.dev.mydomain.com But, I want to this in tomcat manner if possible.

  • Why is Drupal writing to root and not sites/default/files?

    - by Candland
    I'm using Drupal 6.14 on Win7. Everything seems to work except files that should be written to sites/default/files are trying to be written to /. The site was moved from a linux installation, which is writing the files correctly. I have setup a web.config w/ the rewrite rules for drupal. Not sure what or where else I should check. Thanks for any help. <rule name="Drupal Clean URLs" stopProcessing="true"> <match url="^(.*)$" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> </conditions> <action type="Rewrite" url="index.php?q={R:1}" appendQueryString="true" /> </rule>

  • How would I get an img element to render under a background-image in CSS.

    - by Nat Ryall
    Basically, I am trying to put a semi-transparent div over an image to serve as a background for text for a slideshow. Unfortunately, the browser seems intent on always rendering the img over the background-image. Is there any way to fix this? Here is my current CSS for the semi-transparent div: #slideshow .info { height: 80px; margin-top: -80px; background: url(../../images/slideshow-info-pixel.png) repeat; } ... with slideshow-info-pixel.png being a single pixel, 50% opacity, PNG 24. I have so far tried z-index and the CSS must be compatible with IE6.

  • jQuery.get() - Practical uses?

    - by RedWolves
    I am trying to understand why you would use jQuery.get() and jQuery.get(index). The docs say it is to convert the jQuery selection to the raw DOM object instead of working with the selection as a jQuery object and the methods available to it. So a quick example: $("div").get(0).innerHTML; is the same as: $("div").html(); Obviously this is a bad example but I am struggling to figure when you would use .get(). Can you help me understand when I would use this method in my code?

  • Prevent Apache from answering invalid requests

    - by nickdnk
    I have an Apache web-server that acts as a web front-end for iPhone and iPad applications that communicate by POST and JSON only. Is there any way to prevent Apache from answering requests that are invalid? I can see my error log is filled with attempts to open files such as /admin.php /index.php etc - files that don't exist on my server. I believe this is possible with IIS, but can you do the same thing with Apache? Basically I want the request to appear timed out unless you post exactly the right content to the right file - or at least if you do not request an existing file. This would make the server appear non-existing to everyone but my iPhone users as all communication is SSL and directories are not really guess-able. I did disable the ServerTokens and all that, but I still get File not found etc. when I access the server requesting a random file, which is what these bots do constantly.

  • link_to syntax with rails3 (link_to_remote) and basic javascript not working in a rails3 app?

    - by z3cko
    i am wondering if the basic link_to syntax is completely broken in current rails3 master or if i am doing some wrong syntax here. = link_to "name", nil, :onlick => "alert('Hello world!');" should actually produce an alert on click. very simple. does not work on my rails3 project! (also no error output!) any ideas? for the general link_to syntax i could not find an example where i could combine a link_to_remote with a confirmation, remote and html class (see my try below) = link_to "delete", {:action => "destroy", :remote => true, :method => :delete, :confirm => "#{a.title} wirklich L&ouml;schen?" }, :class => "trash" even the rails3 api does not help me here: http://rails3api.s3.amazonaws.com/index.html help!

  • JQuery validation based on class?

    - by Mark Kadlec
    I have a form that will have dynamically created elements, one of those will be of date type. There can also be many fields of this type on my form, all which must be validated. I am using a strongly typed view in Asp MVC, so the name will change based on various factors. What I would like to do is validate based on a class name instead, since that will be constant for that type of field. Ie: <%= Html.TextBox("questionAnswers[" + index + "].AnswerValue", qa.AnswerValue, new { @class = "DateTypeClass" })%> So then I would need JQuery validation based on the classname DateTypeClass versus the Name. Any ideas?

  • How to trigger an event ONLY if both dropdowns are selected?

    - by DaveDev
    I have a dropdown select list on my page of class="TypeFilter". I have a jQuery event that fires when a value in that list is selected. $(".TypeFilter").change(function() { // Extract value from TypeFilter and update page accordingly )); I now have to add another list to the page, and I want to implement functionality which will prevent the .change(function() from running unless both are selected. In both lists the first option in the list is some text instructing the user to select one of the items, so I was thinking of just writing some logic to test that both lists have a selected index greater than 0. I think this is a touch unclean though, especially considering that other pages that have a TypeFilter use the same logic. Is there any nifty functionality in jQuery that can do this?

  • Optimizing Solr for Sorting

    - by devinfoley
    I'm using Solr for a realtime search index. My dataset is about 60M large documents. Instead of sorting by relevance, I need to sort by time. Currently I'm using the sort flag in the query to sort by time. This works fine for specific searches, but when searches return large numbers of results, Solr has to take all of the resulting documents and sort them by time before returning. This is slow, and there has to be a better way. What is the better way?

  • How do I convert a number (as a String) to an array of bytes in Java?

    - by user1795595
    I'm creating a method specific method for a java project i'm working on. The UML given specifies the return type to be of static byte[] that accepts the arguments (String, byte) So far, looks like this: public static byte[] convertNumToDigitArray(String number, byte numDigits) { } This method is supposed to convert a number (as a String) to an array of bytes. The ordering must go from most to least significant digits. For example, if the number String is “732” then index 0 of the array should contain 7. The last argument (numDigits) should match the length of the string passed in. How do I do this?

  • Dropdown menu getting hidden by images

    - by Bob
    I have a set of dropdown menus across the top of a web page. Below is text and some images. When I hover over the top of each menu the menu then expands below as expected but while it overlaps any text on the page it is hidden behind any images. I set the z-index to 9999 and the position is set to absolute. I found if I lower the opacity of the images to say 0.6 then the menu will overlap it. So one solution would be to detect when the menu is being hovered over and then in JavaScript or JQuery temporarily reduce the opacity of the rest of the page until the cursor moves off the menu. If so I'm not sure how to do that but is that the best approach?

  • Flash Builder 'building' html files...

    - by Frank
    I'm using Flash Builder 3 to edit my Flex app, but I noticed that every time I make a change on the .html files (index.template.html for example), even if it's not in the IDE but with another program, Flash Builder rebuilds the whole project. Is there anyway to stop this? Why would it need to rebuild the workspace everytime a html file changes? If it was too long it wouldn't bother me, but it takes a lot of time (more than 1 minute) every time. For your information the html file is 95 lines of 'code'. Thanks

  • Lua not producing table of functions (IO API)

    - by ArtOfCode
    I'm working on a basic project in Lua. I've been trying to get data from files using the IO API (as defined here), but when I open a file and give it a handle, it doesn't seem to return a table of functions. The (erroneous bit of) code: local unread = fs.list("email/"..from.."/") local send = "" for _,file in ipairs(unread) do local handle = io.open(file,"r") local text = handle:read("*a") send = send .. text .. "\n" handle.close() fs.delete(file) end The fs you see on the first line is a professional filesystem wrapper round the IO API, not my work and perfectly error-free, so that's not the problem. However, when I try to read the file (handle:read()), it throws "attempt to index nil". Tracing it, it turns out that handle itself is nil. Any ideas?

  • How do I create a no-javascript url hash handler for my website?

    - by Kenny Bones
    Ok, I'm not sure how this is normally done. But I've got a script that basically empties a div of content and then loads content from a div from a separate webpage, without reloading the current page. This works great. It's taken from this example actually, from net tuts (great site btw) http://nettuts.s3.amazonaws.com/011_jQuerySite/sample/index.html And the guy who wrote this even though about handling the url's since the url don't change when using his method. So he wrote a javascript snippet that looks up the url and loads the content accoringly. Which is not working btw. But I was thinking about people who don't have javascript enabled, or iPhone and iPad users ;) Copying URLs and sending to a friend won't work at all. So how is this typically done? And can it be done without javascript? Possibly by php?

  • Safe way of iterating over an array or dictionary and deleting entries?

    - by mystify
    I've heard that it is a bad idea to do something like this. But I am sure there is some rule of thumb which can help to get that right. When I iterate over an NSMutableDictionary or NSMutableArray often I need to get rid of entries. Typical case: You iterate over it, and compare the entry against something. Sometimes the result is "don't need anymore" and you have to remove it. But doing so affects the index of all the rows, doesn't it? So how could I safely iterate over it without accidently exceeding bounds or jumping over an element that hasn't been checked?

  • Help with implementing a function to change size of dynamic array

    - by iRobot
    I'm trying to write a function that will change the size of a dynamic array to a new size. In my header file, I have: Image **images; //pointer to a dynamic array of image pointers int maximum; //size I want to do this by allocating a new array and copying the values over without changing their indices. If there are non-null pointers outside the range newmax, then we cant do this. So heres what I have: There are no compilation or runtime errors. However, I find that the new array isnt getting sized right. When I run the following test case: I should get an index out of bounds error, but instead the system lets it slide. Can anyone see the mistake? I've looked for hours but cant find anything.
