    - by atif089
    any better way to write this ? $(this).parent().parent().find(" dd ul").toggle(); update.. I am trying to create a dropdown using the script here http://www.jankoatwarpspeed.com/post/2009/07/28/reinventing-drop-down-with-css-jquery.aspx however the script works only for one instance of list and my code works good for multiple instances. Just curious if there is another better way to get parent of a parent in jQuery

  • C++ write to front of file

    - by user231536
    I need to open a file as ofstream and write to the front of the file, while preserving the remaining contents of the file, which will be "moved". Similar to "prepend" a file. Is this possible using the STL or boost ?

  • Need to write a daemon in linux, not sure what to use C++ or C

    - by Bluescrod
    Hello everyone, I have a little problem picking the right language to write my daemon, I am confused between C and C++, I want to use C++ because it is more expanded than C, but I want to use C because it is the starting point of everything in linux, I want to go for C++ as I have many resources about it, so, does it make any difference if I pick C++ instead of C? and what I will have good if I learn C more? I feel like if I go into C++ I will cover C within C++... Regards

  • Write a JavaScript that accepts a number from the user using the “prompt” function

    - by A sw A
    Write a JavaScript that accepts a number from the user using the “prompt” function. Then it draws a table in the HTML document that has the user specified number of rows and columns. In each table data, it displays the result of the math operation (row raised to the power of column). For example, if the user enters the number 3, the JavaScript should draw the following table: 1 1 1 2 4 8 3 9 27

  • Is it possible to write syntax like - ()() ?

    - by dotnetdev
    I read in an ebook somewhere (which I'm desperate to find again), that, by using delegates, it is possible to write code which has syntax as follows: ()(); // where delegate proceeds this. Can anyone provide any details how this would be possible/in what situation this would occur? Thanks

  • How To Edit XML File

    - by thebourneid
    I have a movie collection catalogue with local links to folders and files for an easy access. Recently I reorganaized my entire hard disk space and I need to update the links and I'm trying to do that automatically with perl. I can export the data in a xml file and import it again. I can extract the new filepaths with the use of File::Find but I'm stuck with two problems. I have no idea how to connect the $title from the new filepath with the corresponding $title from the xml file. I'm dealing with such files for the first time and I don't know how to proceed with the replacement process. Here is what I've done till now use strict; use warnings; use File::Basename; use File::Find; use File::Spec; use XML::Simple; use Data::Dumper; my $dir_target = 'somepath'; find(\&a, $dir_target); sub a { /\.iso$/ or return; my $fn = $File::Find::name; $fn =~ s/\//\\/g; $fn =~ /(.*\\)(.*)/; my $path = $1; my $filename = $2; my $title = (File::Spec->splitdir($fn))[2]; $title =~ s/(.*?)\s\(\d+\)$/$1/; $title =~ s/~/:/; $title =~ s/`/?/; my $link_local = '<link><description>Folder</description><url>'.$path.'</url><urltype>Movie</urltype></link><link><description>'.$filename.'</description><url>'.$fn.'</url><urltype>Movie</urltype></link>' unless $title eq ''; my $txt = 'somepath/log.txt'; my $xml_in = XMLin('somepath/test.xml', ForceArray => 1, KeepRoot => 1); my $xml_out = XMLout($xml_in, OutputFile => 'somepath/test_out.xml', KeepRoot=>1); open F, ">>", $txt; print F $link_local."\n\n"; close F; } And here is a snippet of the data I need to edit. If found imdb and dvdempire link - do not touch. if found local links replace, otherwise insert. I'm willing to complete the code myself but need some directions how to proceed further. Thanks. <title>$title</title> ....... <links> <link> <description>IMDB</description> <url>http://www.imdb.com/title/VARIABLE</url> <urltype>URL</urltype> </link> <link> <description>DVD Empire</description> <url>http://www.dvdempire.com/VARIABLE</url> <urltype>URL</urltype> </link> <link> <description>Folder</description> <url>OLD_FOLDERPATH</url> <urltype>Movie</urltype> </link> <link> <description>OLD_FILENAME</description> <url>OLD_FILENAMEPATH</url> <urltype>Movie</urltype> </link> </links>

  • Set width of Button in Android

    - by Mohit Deshpande
    How can I set a fixed width for an Android button? Everytime I try to set a fixed width it fills the current parent (the RelativeView). Here is my XML: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout android:id="@+id/relativelayout" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <EditText android:layout_height="wrap_content" android:editable="false" android:layout_width="fill_parent" android:id="@+id/output"></EditText> <Button android:layout_height="wrap_content" android:id="@+id/Button01" android:layout_below="@id/output" android:text="7" android:layout_width="wrap_content"></Button> <Button android:layout_below="@id/output" android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/Button02" android:layout_toRightOf="@+id/Button01" android:text="8"></Button> <Button android:layout_below="@id/output" android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/Button03" android:layout_toRightOf="@+id/Button02" android:text="9"></Button> </RelativeLayout> How would I give it a FIXED width?

  • web.config, configSource, and "The 'xxx' element is not declared" warning.

    - by UpTheCreek
    I have broken down the horribly unwieldy web.config file into individual files for some of the sections (e.g. connectionStrings, authentication, pages etc.) using the configSource attribute. This is working file, but the individual xml files that hold the section 'snippets' cause warnings in VS. For example, a file named roleManager.config is used for the role manager section, and looks like this: <roleManager enabled="false"> </rolemanager> However I get a blue squiggle under the roleManager element in VS, and the following warning: The 'roleManager' element is not declared I guess this is something to do with valid xml and schemas etc. Is there an easy way to fix this? Something I can add to the individual files? Thanks P.S. I have heard that it is bad practice to break the web.config file out like this. But don't really understand why - can anyone illuminate me?

  • In Protobuf-net how can I pass an array of type object with objects of different types inside, knowi

    - by cloudraven
    I am trying to migrate existing code that uses XmlSerializer to protobuf-net due to the increased performance it offers, however I am having problems with this specific case. I have an object[] that includes parameters that are going to be sent to a remote host (sort of a custom mini rpc facility). I know the set of types from which these parameters can be, but I cannot tell in advance in which order they are going to be sent. I have three constraints. The first is that I am running in Compact Framework, so I need something that works there. Second, as I mentioned performance is a big concern (on the serializing side) so I would rather avoid using a lot of reflection there if possible. And the most important is that I care about the order in which this parameters were sent. Using XmlSerializer it was easy just adding XmlInclude, but for fields there is nothing equivalent as far as I know in Protobuf-net. So, is there a way to do this? Here is a simplified example. [Serializable] [XmlInclude(typeof(MyType1)), XmlInclude(typeof(MyType2)), XmlInclude(typeof(MyType3)) public class Message() { public object[] parameters; public Message(object[] parms) { parameters = parms; } } Message m = new Message(new object[] {MyType1(), 33, "test", new MyType3(), new MyType3()}); MemoryStream ms = new MemoryStream(); XmlSerializer xml = new XmlSerializer(typeof(Message)); xml.Serialize(ms,xml); That will just work with XmlSerializer, but if I try to convert it to protobuf-net I will get a "No default encoding for Object" message. The best I came up with is to use generics and [ProtoInclude] as seen in this example. Since I can have different object types within the array this doesn't quite make it. I added a generic List for each potential type and a property with [ProtoIgnore] with type object[] to add them and get them. I have to use reflection when adding them (to know in which array to put each item) which is not desirable and I still can't preserve the ordering as I just extract all the items on each list one by one and put them into a new object[] array on the property get. I wonder if there is a way to accomplish this?

  • XStream <-> Alternative binary formats (e.g. protocol buffers)

    - by sehugg
    We currently use XStream for encoding our web service inputs/outputs in XML. However we are considering switching to a binary format with code generator for multiple languages (protobuf, Thrift, Hessian, etc) to make supporting new clients easier and less reliant on hand-coding (also to better support our message formats which include binary data). However most of our objects on the server are POJOs with XStream handling the serialization via reflection and annotations, and most of these libraries assume they will be generating the POJOs themselves. I can think of a few ways to interface an alternative library: Write an XStream marshaler for the target format. Write custom code to marshal the POJOs to/from the classes generated by the alternative library. Subclass the generated classes to implement the POJO logic. May require some rewriting. (Also did I mention we want to use Terracotta?) Use another library that supports both reflection (like XStream) and code generation. However I'm not sure which serialization library would be best suited to the above techniques.
