  • How do you set up your JScript (NOT JScript.NET) development environment?

    - by jJack
    In my environment, if I create a class in JScript syntax: class test{ } and then save it to a file named "test.js" and run it with wscript, I get a Microsoft JScript "Syntax error" at line 1. However, if I simply, say, write a function: function getInput() { var wshell = WScript.CreateObject("WScript.Shell"); wshell.Popup ("Do you want to continue?"); return userInput } getInput() and run it the same way, it works. Hopefully, there is something fundamentally wrong with my class definition. If that is the case, I am excited to find out.

  • fb.init events when initialized

    - by oshafran
    Hi I have this code window.fbAsyncInit = function() { FB.init({ appId: 'balblablablbal', status: true, cookie: true, xfbml: false }); }; (function() { var e = document.createElement('script'); e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js'; e.async = true; document.getElementById('fb-root').appendChild(e); } ()); I would like to do something only after those JSs have been loaded (i.e. hook on FB.init event) How can I do that thanks

  • jQuery - How to combine has() and gt()

    - by KatieK
    With jQuery 1.4.2, I can't figure out how to combine has() with :gt. I'd like to select any ul which contains more than 3 lis, so here's what I've tried: $(document).ready(function(){ $("ul.collapse:has(li:gt(2))") .each( function() { $(this).css("border", "solid red 1px"); }); }); This does work with the 1.2.6 jQuery library, but not 1.3.2 or 1.4.2. I'd appreciate any help in understanding what's going on here. Thanks!

  • Basic class returns onject reference instead of Array

    - by php-b-grader
    I have very basic class: class Customer { protected $id; protected $customer; public function __construct($customer_id) { $this->id = $customer_id; return $this->set_customer(); } protected function set_customer() { $query = mysql_query("SELECT * FROM customer WHERE id = '$this->id'"); $this->customer = mysql_fetch_row($query); return $this->customer; } } $customer = new Customer($order->customer->id); print_r($customer); This is not doing what I want it to but I understand why... $customer returns a reference to the Customer Object... But what I want is the MySQL row array from the mysql_fetch_row() call... What am I missing?

  • Get the last N rows in the database in order?

    - by Kristopher
    Let's say I have the following database table: record_id | record_date | record_value -----------+-------------+-------------- 1 | 2010-05-01 | 195.00 2 | 2010-07-01 | 185.00 3 | 2010-09-01 | 175.00 4 | 2010-05-01 | 189.00 5 | 2010-06-01 | 185.00 6 | 2010-07-01 | 180.00 7 | 2010-08-01 | 175.00 8 | 2010-09-01 | 170.00 9 | 2010-10-01 | 165.00 I want to grab the last 5 rows with the data ordered by record_date ASC. This is easy to do with: SELECT * FROM mytable ORDER BY record_date ASC LIMIT 5 OFFSET 4 Which would give me: record_id | record_date | record_value -----------+-------------+-------------- 6 | 2010-07-01 | 180.00 7 | 2010-08-01 | 175.00 3 | 2010-09-01 | 175.00 8 | 2010-09-01 | 170.00 9 | 2010-10-01 | 165.00 But how do I do this when I don't know how many records there are and can't compute the magic number of 4? I've tried this query, but if there are less than 5 records, it results in a negative OFFSET, which is invalid: SELECT * FROM mytable ORDER BY record_date ASC LIMIT 5 OFFSET (SELECT COUNT(*) FROM mytable) - 5; So how do I accomplish this?

  • Razor View Engine and jQuery

    - by rjovic
    Hi, does anybody know how to force Razor View engine to print exact line which is under foreach loop. Code follows : @section head{ <script type="text/javascript" src="@Url.Content("~/Content/Scripts/jquery-1.4.1.js")"></script> <script type="text/javascript" src="@Url.Content("~/Content/Scripts/jquery.progressbar.min.js")"></script> <script type="text/javascript"> $(document).ready(function() { @foreach(var player in Model) { jQuery("#pb@PlayerID").progressBar(); } }); </script> } I tried using $() and jQuery() but in both case razor don't know what to do. Is there any way to force him to print exact this : jQuery("#pb@PlayerID").progressBar(); . I want to have something like this : $(document).ready(function() { $("#pb1").progressBar(); $("#pb2").progressBar(); $("#pb3").progressBar(); }); Thank you in advance!

  • "Ambiguous template specialization" problem

    - by Setien
    I'm currently porting a heap of code that has previously only been compiled with Visual Studio 2008. In this code, there's an arrangement like this: template <typename T> T convert( const char * s ) { // slow catch-all std::istringstream is( s ); T ret; is >> ret; return ret; } template <> inline int convert<int>( const char * s ) { return (int)atoi( s ); } Generally, there are a lot of specializations of the templated function with different return types that are invoked like this: int i = convert<int>( szInt ); The problem is, that these template specializations result in "Ambiguous template specialization". If it was something besides the return type that differentiated these function specializations, I could obviously just use overloads, but that's not an option. How do I solve this without having to change all the places the convert functions are called?

  • Controlling symbol generation in Clojure macros

    - by mikera
    I'm trying (as a self-learning exercise) to create a Clojure macro that will generate code to apply a function to a sequence of integers and sum the result, e.g. f(0) + f(1) + f(2) + f(3) This is my attempt: (defmacro testsum [func n] `(fn [x#] (+ ~@( map (fn [i] `(~func x#)) (range n))))) However something seems to go wrong with the x# gensym and I end up with two different versions of x and hence the function doesn't work: (macroexpand '(testsum inc 3)) gives: (fn* ([x__809__auto__] (clojure.core/+ (inc x__808__auto__) (inc x__808__auto__) (inc x__808__auto__)))) This is pretty much exactly what I want apart from the different 809 and 808 versions of x..... What am I doing wrong? I thought that the auto gensym was meant to create a single unique symbol for exactly this kind of purpose? Is there a better way of doing this?

  • Drawing random circles

    - by ViktorC
    I am trying to draw a cupola circles at random positions in an Android application. I draw them on a bitmap and then draw that bitmap on the canvas. This is the function where a draw the circles: private void drawRandomCircles(int numOfCircles) { Canvas c = new Canvas(b); Paint cPaint = new Paint; cPaitn.setColor(Color.RED); for(int i = 0; i < numOfCircles; i++) { int x = Math.Random % 100; int y = Math.Random % 100; c.drawCircle(x, y, 20, cPaint) } } The Bitmap b is global. And after calling this function I just draw the bitmap in the onDraw method. Now the problem is that I only get one circle drawn on the screen, no matter the size of numOfCircles. Any clue what is happening here?

  • Using JSON Data to Populate a Google Map with Database Objects

    - by MikeH
    I'm revising this question after reading the resources mentioned in the original answers and working through implementing it. I'm using the google maps api to integrate a map into my Rails site. I have a markets model with the following columns: ID, name, address, lat, lng. On my markets/index view, I want to populate a map with all the markets in my markets table. I'm trying to output @markets as json data, and that's where I'm running into problems. I have the basic map displaying, but right now it's just a blank map. I'm following the tutorials very closely, but I can't get the markers to generate dynamically from the json. Any help is much appreciated! Here's my setup: Markets Controller: def index @markets = Market.filter_city(params[:filter]) respond_to do |format| format.html # index.html.erb format.json { render :json => @market} format.xml { render :xml => @market } end end Markets/index view: <head> <script type="text/javascript" src="http://www.google.com/jsapi?key=GOOGLE KEY REDACTED, BUT IT'S THERE" > </script> <script type="text/javascript"> var markets = <%= @markets.to_json %>; </script> <script type="text/javascript" charset="utf-8"> google.load("maps", "2.x"); google.load("jquery", "1.3.2"); </script> </head> <body> <div id="map" style="width:400px; height:300px;"></div> </body> Public/javascripts/application.js: function initialize() { if (GBrowserIsCompatible() && typeof markets != 'undefined') { var map = new GMap2(document.getElementById("map")); map.setCenter(new GLatLng(40.7371, -73.9903), 13); map.addControl(new GLargeMapControl()); function createMarker(latlng, market) { var marker = new GMarker(latlng); var html="<strong>"+market.name+"</strong><br />"+market.address; GEvent.addListener(marker,"click", function() { map.openInfoWindowHtml(latlng, html); }); return marker; } var bounds = new GLatLngBounds; for (var i = 0; i < markets.length; i++) { var latlng=new GLatLng(markets[i].lat,markets[i].lng) bounds.extend(latlng); map.addOverlay(createMarker(latlng, markets[i])); } } } window.onload=initialize; window.onunload=GUnload;

  • Powershell equivilent of python's if __name__ == '__main__':

    - by Mark Mascolino
    I am really fond of python's capability to do things like this: if __name__ == '__main__': #setup testing code here #or setup a call a function with parameters and human format the output #etc... This is nice because I can treat a Python script file as something that can be called from the command line but it remains available for me to import its functions and classes into a separate python script file easily without triggering the default "run from the command line behavior". Does Powershell have a similar facility that I could exploit? And if it doesn't how should I be organizing my library of function files so that i can easily execute some of them while I am developing them?

  • Ambiguous Evaluation of Lambda Expression on Array

    - by Joe
    I would like to use a lambda that adds one to x if x is equal to zero. I have tried the following expressions: t = map(lambda x: x+1 if x==0 else x, numpy.array) t = map(lambda x: x==0 and x+1 or x, numpy.array) t = numpy.apply_along_axis(lambda x: x+1 if x==0 else x, 0, numpy.array) Each of these expressions returns the following error: ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all() My understanding of map() and numpy.apply_along_axis() was that it would take some function and apply it to each value of an array. From the error it seems that the the lambda is being evaluated as x=array, not some value in array. What am I doing wrong? I know that I could write a function to accomplish this but I want to become more familiar with the functional programming aspects of python.

  • Efficient implementation of natural logarithm (ln) and exponentiation

    - by Donotalo
    Basically, I'm looking for implementation of log() and exp() functions provided in C library <math.h>. I'm working with 8 bit microcontrollers (OKI 411 and 431). I need to calculate Mean Kinetic Temperature. The requirement is that we should be able to calculate MKT as fast as possible and with as little code memory as possible. The compiler comes with log() and exp() functions in <math.h>. But calling either function and linking with the library causes the code size to increase by 5 Kilobytes, which will not fit in one of the micro we work with (OKI 411), because our code already consumed ~12K of available ~15K code memory. The implementation I'm looking for should not use any other C library functions (like pow(), sqrt() etc). This is because all library functions are packed in one library and even if one function is called, the linker will bring whole 5K library to code memory.

  • exportDocument() 'destination folder does not exist' error

    - by dvb
    I'm trying to make a script in photoshop that will modify some layers and than export them as a PNG image. I've copied the following code from another place: function SavePNG(saveFile){ var pngOpts = new ExportOptionsSaveForWeb; pngOpts.format = SaveDocumentType.PNG pngOpts.PNG8 = false; pngOpts.transparency = true; pngOpts.interlaced = true; pngOpts.quality = 100; activeDocument.exportDocument(saveFile,ExportType.SAVEFORWEB,pngOpts); } The function export the active document of photoshop to the file specified by the saveFile parameter. It's working fine with simple paths like 'C:\images\result.png' but when trying with different paths like '~/Desktop/' or paths with some special characters the file isn't exported, and a 'destination folder does not exist' error massage appear. Any idea how can I solve it?

  • How can you logically group HTML elements without taking the help of CSS classes ?

    - by Perpetualcoder
    I know that in jQuery you can use something like $(".cssClass") to get all elements with this class. However in plain html and javascript how do you group elements logically? For example: <input id="fee1" data-id="1" data-group="Fees" type="text" value="$15.00"/> <input id="fee2" data-id="2" data-group="Fees" type="text" value="$25.00"/> <input id="fee3" data-id="3" data-group="Fees" type="text" value="$35.00"/> I want to create a javascript function like this: function GetByDataGroup(dataGroup){ /* returns something like [[1,"$15.00"],[2,"$25.00"],[3,"$35.00"]]*/ } EDIT : Due to some political reasons I cant use jQuery or any framework..i know it doesnt make sense :)

  • Void pointer values comparing C++

    - by user2962977
    My actual question is it really possible to compare values contained in two void pointers, when you actually know that these values are the same type? For example int. void compVoids(void *firstVal, void *secondVal){ if (firstVal < secondVal){ cout << "This will not make any sense as this will compare addresses, not values" << endl; } } Actually I need to compare two void pointer values, while outside the function it is known that the type is int. I do not want to use comparison of int inside the function. So this will not work for me as well: if (*(int*)firstVal > *(int*)secondVal) Any suggestions? Thank you very much for help!

  • DllImport Based on OS Platform

    - by Ngu Soon Hui
    I have a mixture of unmanaged code ( backend) and managed code ( front end), as such, I would need to call the unmanaged code from my managed code, using interop techniques and DllImport attribute. Now, I've compiled two versions of unmanaged code, for both 32 and 64 bit OS; they are named service32.dll and service64.dll respectively. So, in my .Net code, I would have to do a DllImport for both dlls: [DllImport(@"service32.dll")] //for 32 bit OS invocation public static void SimpleFunction(); [DllImport(@"service64.dll")] //for 64 bit OS invocation public static void SimpleFunction(); And call them depending on which platform my application is running on. The issue now is that for every unmanaged function, I have to declared it twice, one for 32 bit OS and one for 64 bit OS. This is a duplication of work, and everytime I change the signature of an unmanaged function, I have to modified it in two places. Is there anyway that I can change the argument in DllImport so that the correct dll will be invoked automagically, depending on the platform?

  • Subtracting Delphi Time Ranges from a Date Range, Calculate Remaining Time

    - by Anagoge
    I'm looking for an algorithm that will help calculate a workday working time length. It would have an input date range and then allow subtracting partially or completely intersecting time range slices from that date range and the result would be the number of minutes (or the fraction/multiple of a day) left in the original date range, after subtracting out the various non-working time slices. For Example: Input date range: 1/4/2010 11:21 am - 1/5/2010 3:00 pm Subtract out any partially or completely intersecting slices like this: Remove all day Sunday Non-Sundays remove 11:00 - 12:00 Non-Sundays remove time after 5:00 pm Non-Sundays remove time before 8:00 am Non-Sundays remove time 9:15 - 9:30 am Output: # of minutes left in the input date range I don't need anything overly-general. I could hardcode the rules to simplify the code. If anyone knows of sample code or a library/function somewhere, or has some pseudo-code ideas, I'd love something to start with. I didn't see anything in DateUtils, for example. Even a basic function that calculates the number of minutes of overlap in two date ranges to subtract out would be a good start.

  • PHP - error when insert date into MySQL

    - by Michael Mao
    Hello everyone: I've got a typical problem when trying to insert a date into MySQL. The column defined in MySQL is of type DATE. My PHP version is 5.3.0 Apart from this date-related issue, the rest of my code works just fine. And this is my PHP script to do this: $tablename = BOOKS_TABLE; $insert = mysql_query("INSERT INTO $tablename (barcode, book_name, volume_num,". " author, publisher, item_type, buy_price, buy_date) VALUES ". "(". "'" . $barcode . "', ". "'" . $bookname . "', ". "'" . $volumenum . "', ". "'" . $author . "', ". "'" . $publisher . "', ". "'" . $itemtype . "', ". "'" . $buyprice . "', ". "'" . getMySQLDateString($buydate). //"'STR_TO_DATE('".$buydate ."', '%d/%m/%Y'))'". //nothing changes in MySQL ")"); And this is the faulty function : function getMySQLDateString($buydate) //typical buydate : 04/21/2009 { $mysqlDateString = date('Y-m-d H:i:s', $strtotime($buydate)); return $mysqlDateString; } The first commented out line wouldn't do anything, the script is executed with no error, however, there is nothing changed in datebase after this. The current approach will cause a Fatal error saying function name must be a string in this line. Actually I followed this thread on SO, but just cannot pass the date into MySQL... Can anyone help me figure out which part is not right? How would you do it, in this case, to get it right? Sorry about such a journeyman-like question, thanks a lot in advance.

  • Problem in passing arrays from C# to C++

    - by Rakesh K
    Hi, I have an application in which I need to pass an array from C# to a C++ DLL. What is the best method to do it? I did some search on Internet and figured out that I need to pass the arrays from C# using ref. The code for the same: status = IterateCL(ref input, ref output); The input and output arrays are of length 20. and the corresponding code in C++ DLL is IterateCL(int *&inArray, int *&outArray) This works fine for once. But if I try to call the function from C# in a loop the second time, the input array in C# is showing up as an array of one element. Why is this happening and please help me how I can call this function iteratively from C#. Thanks, Rakesh.
