  • Always require a plugin to be loaded

    - by axon
    I am writing an application with RequireJS and Knockout JS. The application includes an extension to knockout that adds ko.protectedObservable to the main knockout object. I would like this to always be available on the require'd knockout object, and not only when I specify it in the dependencies. I could concat the files together, but that seems that it should be unnecessary. Additionally, I can put knockout-protectedObservable as a dependency for knockout in the requirejs shim configuration, but that just leads to a circular dependency and it all fails to load. Edit: I've solved me issue, but seems hacky, is there a better way? -- Main.html <script type="text/javascript" src="require.js"></script> <script type="text/javascript"> require(['knockout'], function(ko) { require(['knockout-protectedObservable']); }); </script> -- knockout-protectedObservable.js define(['knockout'], function(ko) { ko.protectedObservable = { ... }; });

  • What is the correct method to load an XML file and re-write it as a CVS? (C# Only)

    - by codesmack
    Hello, I have a XML file that I want to load into an unknown object type. (I say unknown object type because I am not sure what direction to go) Once I have the data loaded I need to do some processing on certain elements that are now loaded into the new object. For sake of example, we can say that the xml file is full of elements named and within the car element I need to process the element. Then once this is all done I need to write the file as a CSV file. I would like to do this is the most direct way possible. (The less code the better) I am using VS 2008 C# Thank you, CodeSmack

  • Confused about adding multiple td's to tr using jQuery

    - by Jason
    So I have the following code: <script type="text/javascript"> $(document).ready( function () { $("#txt").click(function () { var $TableRow = $('<tr></tr>'); var $TableData = $('<td></td>'); var $TableData2 = $('<td></td>'); // Works $("#tblControls").append( $TableRow.html( $TableData.text("Test, Hello World3") ) ); </script> <div style="display: inline"> <input type="button" id="txt" value="Add TextBox" style="" /> </div> <br/> <table id="tblControls" width="100%"> </table> But why does this not add two td's to the tr? $("#tblControls").append( $TableRow.html( $TableData.text("Test, Hello World3") + $TableData2.text("Test, Hello World4") ) ); What I get is this: [object Object][object Object]

  • Contact form with php-script does not work

    - by elajjas
    I'm new to the forum and I have been trying to find a thread that could be helpful but nothing have been working out so far. I recently uploaded my site via FTP, and it works fine. Except for one thing, my contact form. The contact form is crucial and it is almost the whole point of the website. I don't get any emails "from the form", either in my spam-folder or inbox. Please have a look at the website which is: http://www.adspot.se The contact form is situated on: http://www.adspot.se/contact.html The php script looks like this: <?php if (isset($_REQUEST['email'])) //if "email" is filled out, send email { //send email $name = $_REQUEST['name'] ; $email = $_REQUEST['email'] ; $message = $_REQUEST['message'] ; mail("[email protected]", $name, $message, "From:" . $email); } ?> I've already tried different types of php-scripts, but it still doesn't seem to work. UPDATE: Changed the form code to: <form method="POST" action="email.php"> <div class="row half"> <div class="6u"> <input name="name" placeholder="Name" type="text" class="text" /> </div> <div class="6u"> <input name="email" placeholder="Email" type="text" class="text" /> </div> </div> <div class="row half"> <div class="12u"> <textarea name="message" placeholder="Message"></textarea> </div> </div> <div class="row half"> <div class="12u"> <ul class="action"> <input type="submit" class="action"> </ul> </div> </div> </form> Now it redirects me to www.adspot.se/email.php but still no emails received...

  • Data on the Frequency of Edit Operations Required to Correct a Misspelt Word

    - by gvkv
    Does anybody know of any data that relates to the frequency of the types of mistakes the people make when they misspell a word? I'm not referring to words themselves, but tje errors that are made by the typist. For example, I personally make transposition errors the most followed by deletion errors (that is, not including a letter I should), substitution errors and lastly, insertion errors. However, it would not surprise me to find out that typing a wrong letter (a substitution error, e.g., xat instead of cat) is more frequent than not including a letter. My purpose is to be able to make best guesses at correcting a word when I only have the original user's input. The idea being that if one type of error is more frequent than others, then it's more likely that correcting a word via that type of operation is correct. I don't object to using a database of commonly misspelt words but I prefer an algorithmic solution to depending on a corpus--especially if it might be faster.

  • How to add http headers in suds 0.3.6?

    - by Esabe
    Hi everyone, I have an application in python 2.5 which sends data through suds 0.3.6. The problem is that the data contains non-ascii characters, so I need the following header to exist in the soap message: Content-Type="text/html; charset="utf-8" and the header that exists in the SOAP message is just: Content-Type="text/html" I know that it is fixed in suds 0.4, but it requires Python2.6 and I NEED Python2.5 because I use CentOS and it needs that version. So the question is: How could I change or add new HTTP headers to a SOAP message?

  • How to get global access to enum types in C#?

    - by lala
    This is probably a stupid question, but I can't seem to do it. I want to set up some enums in one class like this: public enum Direction { north, east, south, west }; Then have that enum type accessible to all classes so that some other class could for instance have: Direction dir = north; and be able to pass the enum type between classes: public void changeDirection(Direction direction) { dir = direction; } I thought that setting the enum to public would make this automatically possible, but it doesn't seem to be visible outside of the class I declared the enum in.

  • How can I merge CSS definitions in files into inline style attributes, using Perl?

    - by mintywalker
    Many email clients don't like linked CSS stylesheets, or even the embedded <style> tag, but rather want the CSS to appear inline as style attributes on all your markup. BAD: <link rel=stylesheet type="text/css" href="/style.css"> BAD: <style type="text/css">...</style> WORKS: <h1 style="margin: 0">...</h1> However this inline style attribute approach is a right pain to manage. I've found tools for Ruby and PHP that will take a CSS file and some separate markup as input and return you the merged result - a single file of markup with all the CSS converted to style attributes. I'm looking for a Perl solution to this problem, but I've not found one on CPAN or by searching Google. Any pointers? Alternatively, are there CPAN modules one could combine to achieve the same result? Ruby http://code.dunae.ca/premailer.web/ PHP http://www.pelagodesign.com/sidecar/emogrifier/ Perl ?

  • How to change input button image using CSS?

    - by Baltimark
    So, I can create an input button with an image using <INPUT type="image" src="/images/Btn.PNG" value=""> But, I can't get the same behavior using CSS. for instance, i've tried <INPUT type="image" class="myButton" value=""> where "myButton" is defined in the css file as .myButton{ background:url(/images/Btn.PNG) no-repeat; cursor:pointer; width: 200px; height: 100px; border: none; } If that's all I wanted to do, I could use the original style, but I want to change the button's appearance on hover (using a myButton:hover class). I know the links are good because I've been able to load them for a background image for other parts of the page (just as a check). I found examples on the web of how to do it using javascript, but I'm looking for a css solution. I'm using Firefox 3.0.3 if that makes a difference. Thanks

    I'm working on a little parsing thing to color objects. For an example, you could type red:Hi!: and "Hi!" would be red. This is my not working code: <script type="text/javascript"> function post() { var preview = document.getElementById("preview"); var submit = document.getElementById("post"); var text = submit.value; <?php str_replace("red:*:",'<i class="red">*</i>',text); ?> preview.value = text; } </script>

    Hi all, I have a method void foo(list<shared_ptr<Base>>& myList); Which I'm trying to call with a two different types of lists, one of DerivedClass1 and one of DerivedClass2 list<shared_ptr<DerivedClass1>> myList1; foo(myList1); list<shared_ptr<DerivedClass2>> myList2; foo(myList2); However this obviously generates a compiler error error: a reference of type "std::list<boost::shared_ptr<Base>, std::allocator<boost::shared_ptr<Base>>> &" (not const-qualified) cannot be initialized with a value of type "std::list<boost::shared_ptr<DerivedClass1>, std::allocator<boost::shared_ptr<DerivedClass1>>>" Is there any easy way to cast a container of shared_ptr? Of alternate containers that can accomplish this?

  • Passing javascript form variables into jQuery function not working

  • C++ segmentation error when first parameter is null in comparison operator overload

    - by user1774515
    I am writing a class called Word, that handles a c string and overloads the <, , <=, = operators. word.h: friend bool operator<(const Word &a, const Word &b); word.cc: bool operator<(const Word &a, const Word &b) { if(a == NULL && b == NULL) return false; if(a == NULL) return true; if(b == NULL) return false; return a.wd < b.wd; //wd is a valid c string } main: char* temp = NULL; //EDIT: i was mistaken, temp is a char pointer Word a("blah"); //a.wd = [b,l,a,h] cout << (temp<a); i get a segmentation error before the first line of the operator< method after the last line in the main. I can correct the problem by writing cout << (a>temp); where the operator> is similarly defined and i get no errors. but my assignment requires (temp < a) to work so this is where i ask for help. EDIT: i made a mistake the first time and i said temp was of type Word, but it is actually of type char*. so i assume that the compiler converts temp to a Word using one of my constructors. i dont know which one it would use and why this would work since the first parameter is not Word. here is the constructor i think is being used to make the Word using temp: Word::Word(char* c, char* delimeters=NULL) { char *temporary = "\0"; if(c == NULL) c = temporary; check(stoppers!=NULL, "(Word(char*,char*))NULL pointer"); //exits the program if the expression is false if(strlen(c) == 0) size = DEFAULT_SIZE; //10 else size = strlen(c) + 1 + DEFAULT_SIZE; wd = new char[size]; check(wd!=NULL, "Word(char*,char*))heap overflow"); delimiters = new char[strlen(stoppers) + 1]; //EDIT: changed to [] check(delimiters!=NULL,"Word(char*,char*))heap overflow"); strcpy(wd,c); strcpy(delimiters,stoppers); count = strlen(wd); } wd is of type char* thanks for looking at this big question and trying to help. let me know if you need more code to look at

  • Can MySQL reasonably perform queries on billions of rows?

    - by haxney
    I am planning on storing scans from a mass spectrometer in a MySQL database and would like to know whether storing and analyzing this amount of data is remotely feasible. I know performance varies wildly depending on the environment, but I'm looking for the rough order of magnitude: will queries take 5 days or 5 milliseconds? Input format Each input file contains a single run of the spectrometer; each run is comprised of a set of scans, and each scan has an ordered array of datapoints. There is a bit of metadata, but the majority of the file is comprised of arrays 32- or 64-bit ints or floats. Host system |----------------+-------------------------------| | OS | Windows 2008 64-bit | | MySQL version | 5.5.24 (x86_64) | | CPU | 2x Xeon E5420 (8 cores total) | | RAM | 8GB | | SSD filesystem | 500 GiB | | HDD RAID | 12 TiB | |----------------+-------------------------------| There are some other services running on the server using negligible processor time. File statistics |------------------+--------------| | number of files | ~16,000 | | total size | 1.3 TiB | | min size | 0 bytes | | max size | 12 GiB | | mean | 800 MiB | | median | 500 MiB | | total datapoints | ~200 billion | |------------------+--------------| The total number of datapoints is a very rough estimate. Proposed schema I'm planning on doing things "right" (i.e. normalizing the data like crazy) and so would have a runs table, a spectra table with a foreign key to runs, and a datapoints table with a foreign key to spectra. The 200 Billion datapoint question I am going to be analyzing across multiple spectra and possibly even multiple runs, resulting in queries which could touch millions of rows. Assuming I index everything properly (which is a topic for another question) and am not trying to shuffle hundreds of MiB across the network, is it remotely plausible for MySQL to handle this? UPDATE: additional info The scan data will be coming from files in the XML-based mzML format. The meat of this format is in the <binaryDataArrayList> elements where the data is stored. Each scan produces = 2 <binaryDataArray> elements which, taken together, form a 2-dimensional (or more) array of the form [[123.456, 234.567, ...], ...]. These data are write-once, so update performance and transaction safety are not concerns. My naïve plan for a database schema is: runs table | column name | type | |-------------+-------------| | id | PRIMARY KEY | | start_time | TIMESTAMP | | name | VARCHAR | |-------------+-------------| spectra table | column name | type | |----------------+-------------| | id | PRIMARY KEY | | name | VARCHAR | | index | INT | | spectrum_type | INT | | representation | INT | | run_id | FOREIGN KEY | |----------------+-------------| datapoints table | column name | type | |-------------+-------------| | id | PRIMARY KEY | | spectrum_id | FOREIGN KEY | | mz | DOUBLE | | num_counts | DOUBLE | | index | INT | |-------------+-------------| Is this reasonable?

  • Get the affinity of a SQLite column on Android

    - by Neil Traft
    The SQLite C library has a method, sqlite3_column_decltype(). But I cannot find any place where the Android SQLite API makes this method available. Is there any way to get the declared type of a column without running any SQL (i.e. can I avoid using PRAGMA table_info)? I could have used AbstractWindowedCursor.isBlob(), but it says that it will also return true if the field is NULL. I need something that will guarantee me a value equal to the column's declared type.

  • .NET 2.0: Invoking Methods Using Reflection And Generics Causes Exception

    - by David Derringer
    Hi all, I'm new to Stack Overflow, so forgive me. I've just started transititoning over to C# and I am stuck on a problem. I am wanting to pass a generic class in and call a method from that class. So, my code looks as such: public void UpdateRecords<T>(T sender) where T : new() //where T: new() came from Resharper { Type foo = Type.GetType(sender.GetType().ToString()); object[] userParameters = new object[2]; userParameters[0] = x; userParameters[1] = y; sender = new T(); //This was to see if I could solve my exception problem MethodInfo populateRecord = foo.GetMethod("MethodInOtherClass"); populateMethod.Invoke(sender, userParameters); } Exception thrown: "Object reference not set to an instance of an object." Again, I really apologize, as I am nearly brand new to C# and this is the first time I've ever handled reflection and generics. Thank you!
