  • Concatenate & Minify JS on the fly OR at build time - ASP.NET MVC

    - by Charlino
    As an extension to this question here Linking JavaScript Libraries in User Controls I was after some examples of how people are concatinating & minifying javascript on the fly OR at build time. I would also like to see how it then works into your master pages. I don't mind page specific files being minified and linked inidividually as they currently are (see below) but all the js files on the main master page (I have about 5 or 6) I would like concatenated and minified. Bonus points for anyone who also incorporates CSS concatenation & minification! :-) Current master page with the common js files that I would like concatenated & minified: <%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %> <head runat="server"> ... BLAH ... <asp:ContentPlaceHolder ID="AdditionalHead" runat="server" /> ... BLAH ... <%= Html.CSSBlock("/styles/site.css") %> <%= Html.CSSBlock("/styles/jquery-ui-1.7.1.css") %> <%= Html.CSSBlock("/styles/jquery.lightbox-0.5.css") %> <%= Html.CSSBlock("/styles/ie6.css", 6) %> <%= Html.CSSBlock("/styles/ie7.css", 7) %> <asp:ContentPlaceHolder ID="AdditionalCSS" runat="server" /> </head> <body> ... BLAH ... <%= Html.JSBlock("/scripts/jquery-1.3.2.js", "/scripts/jquery-1.3.2.min.js") %> <%= Html.JSBlock("/scripts/jquery-ui-1.7.1.js", "/scripts/jquery-ui-1.7.1.min.js") %> <%= Html.JSBlock("/scripts/jquery.validate.js", "/scripts/jquery.validate.min.js") %> <%= Html.JSBlock("/scripts/jquery.lightbox-0.5.js", "/scripts/jquery.lightbox-0.5.min.js") %> <%= Html.JSBlock("/scripts/global.js", "/scripts/global.min.js") %> <asp:ContentPlaceHolder ID="AdditionalJS" runat="server" /> </body> Used in a page like this (which I'm happy with): <asp:Content ID="signUpContent" ContentPlaceHolderID="AdditionalJS" runat="server"> <%= Html.JSBlock("/scripts/pages/account.signup.js", "/scripts/pages/account.signup.min.js") %> </asp:Content> EDIT: What I'm using now Since asking this question, Microsoft have released their own JS & CSS compression library called Microsoft AJAX Minifier, I'd definitely recommend checking it out. It includes MSBuild tasks which are the duck's nuts.

  • Masked Time control in WPF

    - by Ashish Ashu
    We are in need of a control in which we can show the elapsed time in "Hour:Min:Sec" format. This control should have a spin control attached with it. Whenever we spin the spin window, it should increment the selected option ( Either hour, or min , or sec). Also the Hour may have values between 0 to 99 , Min many have values between 0 to 59 and Sec may have values between 0 to 59. Is anybody know this type of control in WPF?

  • Convert RGB value to HSV

    - by marionmaiden
    I've found a method on the Internet to convert RGB values to HSV values. Unfortunately, when the values are R=G=B, I'm getting a NaN, because of the 0/0 operation. Do you know if there is an implemented method for this conversion in Java, or what do I have to do when I get the 0/0 division to get the right value of the HSV? Here comes my method, adapted from some code on the Internet: public static double[] RGBtoHSV(double r, double g, double b){ double h, s, v; double min, max, delta; min = Math.min(Math.min(r, g), b); max = Math.max(Math.max(r, g), b); // V v = max; delta = max - min; // S if( max != 0 ) s = delta / max; else { s = 0; h = -1; return new double[]{h,s,v}; } // H if( r == max ) h = ( g - b ) / delta; // between yellow & magenta else if( g == max ) h = 2 + ( b - r ) / delta; // between cyan & yellow else h = 4 + ( r - g ) / delta; // between magenta & cyan h *= 60; // degrees if( h < 0 ) h += 360; return new double[]{h,s,v}; }

  • Macro doesn't work in the function.

    - by avp
    I have problems with following code: http://lisper.ru/apps/format/96 The problem is in "normalize" function, which does not work. It fails on the fifth line: (zero-p a indexes i) (defun normalize (a &optional indexes i) "Returns normalized A." (pragma (format t "Data=~A ~A ~A" a indexes i) (if (zero-p a indexes i) a ;; cannot normalize empty vector (let* ((mmm (format t "Zero?=~a" (zero-p a indexes i))) (L (sqrt (+ (do-op-on * a :x a :x indexes i indexes i) (do-op-on * a :y a :y indexes i indexes i) (do-op-on * a :z a :z indexes i indexes i)))) (mmm (format t "L=~a" L)) (L (/ 1D0 L)) (mmm (format t "L=~a" L))) ; L=1/length(A) (make-V3 (* (ref-of a :x indexes i) l) (* (ref-of a :y indexes i) l) (* (ref-of a :z indexes i) l)))))) in function "normalize" I call the macro "zero-p", which in turn calls macro "ref-of", which is the last in the chain. (defmacro zero-p (v &optional indexes index) "Checks if the vector is 'almost' zero length." `(and (< (ref-of ,v :x ,indexes ,index) *min+*) (< (ref-of ,v :y ,indexes ,index) *min+*) (< (ref-of ,v :z ,indexes ,index) *min+*) (> (ref-of ,v :x ,indexes ,index) *min-*) (> (ref-of ,v :y ,indexes ,index) *min-*) (> (ref-of ,v :z ,indexes ,index) *min-*))) Here is ref-of: (defmacro ref-of (values coordinate &optional indexes index) "Please see DATA STRUCTURE for details." (if indexes (cond ((eq coordinate :x) `(aref ,values (aref ,indexes ,index))) ((eq coordinate :y) `(aref ,values (+ 1 (aref ,indexes ,index)))) ((eq coordinate :z) `(aref ,values (+ 2 (aref ,indexes ,index)))) (T (error "The symbol ~S is not :X, :Y or :Z." coordinate))) (cond ((eq coordinate :x) `(aref ,values 0)) ((eq coordinate :y) `(aref ,values 1)) ((eq coordinate :z) `(aref ,values 2)) (T (error "The symbol ~S is not :X, :Y or :Z." coordinate))))) Also, in "normalize" I call the macro "do-op-on", which calls "ref-of" as well. (defmacro do-op-on (op name1 coord1 name2 coord2 &optional is1 i1 is2 i2) "Example: (do-op-on * A :x B :y i n) == A[i[n]].x*B.y" `(,op (ref-of ,name1 ,coord1 ,is1 ,i1) (ref-of ,name2 ,coord2 ,is2 ,i2))) As a result, instead of having this: (aref some-array 0) I have (aref NIL NIL) which is created in "ref-of". I suppose that I lose the symbol A from the call (normalize A). I just feel that the symbol does not survive the macroexpanson. The thing is, macroexpansoin works in REPL for each macro independently. Can anyone explain where is the mistake?

  • Neural Networks in C# using NeuronDotNet

    - by kingrichard2005
    Hello, I'm testing the NeuronDotNet library for a class assignment using C#. I have a very simple console application that I'm using to test some of the code snippets provided in the manual fro the library, the goal of the assignment is to teach the program how to distinguish between random points in a square which may or may not be within a circle that is also inside the square. So basically, which points inside the square are also inside the circle. Here is what I have so far: namespace _469_A7 { class Program { static void Main(string[] args) { //Initlaize the backpropogation network LinearLayer inputLayer = new LinearLayer(2); SigmoidLayer hiddenLayer = new SigmoidLayer(8); SigmoidLayer outputLayer = new SigmoidLayer(2); new BackpropagationConnector(inputLayer, hiddenLayer); new BackpropagationConnector(hiddenLayer, outputLayer); BackpropagationNetwork network = new BackpropagationNetwork(inputLayer, outputLayer); //Generate a training set for the ANN TrainingSet trainingSet = new TrainingSet(2, 2); //TEST: Generate random set of points and add to training set, //for testing purposes start with 10 samples; Point p; Program program = new Program(); //Used to access randdouble function Random rand = new Random(); for(int i = 0; i < 10; i++) { //These points will be within the circle radius Type A if(rand.NextDouble() > 0.5) { p = new Point(rand.NextDouble(), rand.NextDouble()); trainingSet.Add(new TrainingSample(new double[2] { p.getX(), p.getY() }, new double[2] { 1, 0 })); continue; } //These points will either be on the border or outside the circle Type B p = new Point(program.randdouble(1.0, 4.0), program.randdouble(1.0, 4.0)); trainingSet.Add(new TrainingSample(new double[2] { p.getX(), p.getY() }, new double[2] { 0, 1 })); } //Start network learning network.Learn(trainingSet, 100); //Stop network learning //network.StopLearning(); } //generates a psuedo-random double between min and max public double randdouble(double min, double max) { Random rand = new Random(); if (min > max) { return rand.NextDouble() * (min - max) + max; } else { return rand.NextDouble() * (max - min) + min; } } } //Class defines a point in X/Y coordinates public class Point { private double X; private double Y; public Point(double xVal, double yVal) { this.X = xVal; this.Y = yVal; } public double getX() { return X; } public double getY() { return Y; } } } This is basically all that I need, the only question I have is how to handle output?? More specifically, I need to output the value of the "step size" and the momentum, although it would be nice to output other information as well. Anyone with experience using NeuronDotNet, your input is appreciated.

  • Special case when calling InvokeScript with the winforms WebBrowser control does not work

    - by wang-min
    I am trying to use InvokeScript method on the WebBrowser control to execute a script on the web page that has been loaded into my WebBrowser control. If I am calling just a simple javascript function, this works properly. However, the javascript function that I am trying to call is nested within a variable like this: var holder = { DoA: function() { .... }, DoB: function() { ..... } } Calling holder.DoA works fine when called from within the javascript, but the function is not called successfully when I try to call it from within my C# code like this: object obj1 = m_webBrowser.Document.InvokeScript("holder.DoA"); Any ideas?

  • Linq : problem with primary key

    - by Nickson
    I get the following error message The table/view 'TABLE1' does not have a primary key defined and no valid primary key could be inferred. This table/view has been excluded. To use the entity you will need to review your schema, add the correct keys and uncomment it when I try to add a view to an Entity Data Model. For testing, I have created a very simple view and I still get the error. below is the view definition SELECT DISTINCT TOP (100) PERCENT MIN(id) AS Expr4, MIN(EmpNo) AS Expr1, MIN(Name) AS Expr2, MIN(Category) AS Expr3 FROM dbo.MYView1 GROUP BY id does any one know of a simple work around. I have looked at this thread http://stackoverflow.com/questions/745341/can-ms-sql-views-have-primary-and-foriegn-keys but in my scenario, what is recommended is not applicable. If I could only have the view added to the Model.

  • Kendo UI, searchable Combobox

    - by user2083524
    I am using the free Kendo UI Core Framework. I am looking for a searchable Combobox that fires the sql after inserting, for example, 2 letters. Behind my Listbox there are more than 10000 items and now it takes too much time when I load or refresh the page. Is it possible to trigger the sql query only by user input like the autocomplete widget do? My code is: <link href="test/styles/kendo.common.min.css" rel="stylesheet" /> <link href="test/styles/kendo.default.min.css" rel="stylesheet" /> <script src="test/js/jquery.min.js"></script> <script src="test/js/kendo.ui.core.min.js"></script> <script> $(document).ready(function() { var objekte = $("#objekte").kendoComboBox({ placeholder: "Objekt auswählen", dataTextField: "kurzname", dataValueField: "objekt_id", minLength: 2, delay: 0, dataSource: new kendo.data.DataSource({ transport: { read: "test/objects.php" }, schema: { data: "data" } }), }).data("kendoComboBox"); </script>

  • sqlcipher command line not working

    - by Min Lin
    I have a encrypted sqlite db and its key. (Which is generated by an android program). However, when I open the db in command line I can not read the db. The command line tool is installed by: brew install sqlcipher I open the database by: sqlcipher EnDB.db >pragma key="6b74fcd"; >select * from bizinfo; It keeps telling me "Error: file is encrypted or is not a database" However, if I open the database file with gui app sqlite database browser (which is a windows program and I run it in wine). It pops up a window for me to enter the key, with 6b74fcd as the key it successfully read the database. As I want to automatically process the db in the future, I can not depend on the GUI. Do you know why the command line is not working?

  • Jquery: How can I place triggers on images already cached?

    - by FLX
    Please see: hxxp://flx.me/h/0504/ Source: hxxp://pastebin.com/bDh5k3Qd jquery.preload-min.js: hxxp://jquery.com/plugins/project/Preload jquery.jplayer.min.js: hxxp://www.happyworm.com/jquery/jplayer/0.2.4/developer-guide.htm I'm using jquery.preload-min.js to preload images and to send a play trigger to jquery.jplayer.min.js to start playing a mp3 file. This works great when viewing the page for the first time (or force reloading all content). However, when the image has already been cached, it doesn't use the preloading script and thus does not send the play trigger to jplayer. How can I make it send a play trigger even when the image is cached? Thank you in advance, Dennis

  • Template Sort In C++

    - by wdow88
    Hey all, I'm trying to write a sort function but am having trouble figuring out how to initialize a value, and making this function work as a generic template. The sort works by: Find a pair =(ii,jj)= with a minimum value = ii+jj = such at A[ii]A[jj] If such a pair exists, then swap A[ii] and A[jj] else break; The function I have written is as follows: template <typename T> void sort(T *A, int size) { T min =453; T temp=0; bool swapper = true; while(swapper) { swapper = false; int index1 = 0, index2 = 0; for (int ii = 0; ii < size-1; ii++){ for (int jj = ii + 1; jj < size; jj++){ if((min >= (A[ii]+A[jj])) && (A[ii] > A[jj])){ min = (A[ii]+A[jj]); index1 = ii; index2 = jj; swapper = true; } } } if (!swapper) return; else { temp = A[index1]; A[index1] = A[index2]; A[index2] = temp; sort(A,size); } } } This function will successfully sort an array of integers, but not an array of chars. I do not know how to properly initialize the min value for the start of the comparison. I tried initializing the value by simply adding the first two elements of the array together (min = A[0] + A[1]), but it looks to me like for this algorithm it will fail. I know this is sort of a strange type of sort, but it is practice for a test, so thanks for any input.

  • Memory problems while code is running (Python, Networkx)

    - by MIN SU PARK
    I made a code for generate a graph with 379613734 edges. But the code couldn't be finished because of memory. It takes about 97% of server memory when it go through 62 million lines.

  • Eliminate subquery for average numeric value

  • Java algorithm for normalizing audio

    - by Marty Pitt
    I'm trying to normalize an audio file of speech. Specifically, where an audio file contains peaks in volume, I'm trying to level it out, so the quiet sections are louder, and the peaks are quieter. I know very little about audio manipulation, beyond what I've learnt from working on this task. Also, my math is embarrassingly weak. I've done some research, and the Xuggle site provides a sample which shows reducing the volume using the following code: (full version here) @Override public void onAudioSamples(IAudioSamplesEvent event) { // get the raw audio byes and adjust it's value ShortBuffer buffer = event.getAudioSamples().getByteBuffer().asShortBuffer(); for (int i = 0; i < buffer.limit(); ++i) buffer.put(i, (short)(buffer.get(i) * mVolume)); super.onAudioSamples(event); } Here, they modify the bytes in getAudioSamples() by a constant of mVolume. Building on this approach, I've attempted a normalisation modifies the bytes in getAudioSamples() to a normalised value, considering the max/min in the file. (See below for details). I have a simple filter to leave "silence" alone (ie., anything below a value). I'm finding that the output file is very noisy (ie., the quality is seriously degraded). I assume that the error is either in my normalisation algorithim, or the way I manipulate the bytes. However, I'm unsure of where to go next. Here's an abridged version of what I'm currently doing. Step 1: Find peaks in file: Reads the full audio file, and finds this highest and lowest values of buffer.get() for all AudioSamples @Override public void onAudioSamples(IAudioSamplesEvent event) { IAudioSamples audioSamples = event.getAudioSamples(); ShortBuffer buffer = audioSamples.getByteBuffer().asShortBuffer(); short min = Short.MAX_VALUE; short max = Short.MIN_VALUE; for (int i = 0; i < buffer.limit(); ++i) { short value = buffer.get(i); min = (short) Math.min(min, value); max = (short) Math.max(max, value); } // assign of min/max ommitted for brevity. super.onAudioSamples(event); } Step 2: Normalize all values: In a loop similar to step1, replace the buffer with normalized values, calling: buffer.put(i, normalize(buffer.get(i)); public short normalize(short value) { if (isBackgroundNoise(value)) return value; short rawMin = // min from step1 short rawMax = // max from step1 short targetRangeMin = 1000; short targetRangeMax = 8000; int abs = Math.abs(value); double a = (abs - rawMin) * (targetRangeMax - targetRangeMin); double b = (rawMax - rawMin); double result = targetRangeMin + ( a/b ); // Copy the sign of value to result. result = Math.copySign(result,value); return (short) result; } Questions: Is this a valid approach for attempting to normalize an audio file? Is my math in normalize() valid? Why would this cause the file to become noisy, where a similar approach in the demo code doesn't?

  • Getting maximum value of float in SQL programatically

    - by Axarydax
    Is there an method for programatically (in T-SQL) retrieving the maximum (and minimum) value of a datatype? That it would act like float.MaxValue in C#. I would like to use it in some selection when the parameter does not equal any actual values in the database, so I would use something like declare @min float declare @max float /*fill @min and @max, can be null if undefined*/ select * from foo where bar between isnull(@min,0 ), isnull(@max,max(float)/*magic*/) Thanks

  • C# program for finding how many numbers are devidable by 5 in give range

    - by user1639735
    My task is: Write a program that reads two positive integer numbers and prints how many numbers p exist between them such that the reminder of the division by 5 is 0 (inclusive). Example: p(17,25) = 2. Console.Write("Enter min: "); int min = int.Parse(Console.ReadLine()); Console.Write("Enter max: "); int max = int.Parse(Console.ReadLine()); Console.WriteLine("The numbers devidable by 5 without remainder from {0} to {1} are: ",min,max); for (int i = min; i <= max; i++) { if (i % 5 == 0) { Console.WriteLine(i); } } This prints out the numbers that are devidable by 5 in the range...How do I count how many are there and print the count in the console? Thanks.

  • Add User to Database not working

    - by user1850189
    I'm really new to ASP.net and I am currently trying to create a registration page on a site. I was successful in adding a user to the database but I decided to add another feature into the code to check what userID's were available. For example, if a user deleted their account their userID would become available for use again. I'm trying to find the min value and the max value and add or subtract 1 depending on whether it is min or max. I can run the code I have written for this with no errors but the user is not added to the database. Can anyone help me figure out what I'm missing from my code to do this? EDIT Code adds a user to database but it adds the new user at -1 instead. I don't seem to be able to see where the issue is. If (aDataReader2.Read() = False) Then aConnection1 = New OleDbConnection(aConnectionString) aConnection1.Open() aQuery = "Insert Into UserDetails " aQuery = aQuery & "Values ('" & userID & "','" & userFName & "','" & userLName & "','" & userEmail & "','" & userUsername & "','" & userPassword & "')" aCommand = New OleDbCommand(aQuery, aConnection1) aCommand.ExecuteNonQuery() aConnection1.Close() ElseIf (min = 1) Then aConnection2 = New OleDbConnection(aConnectionString) aConnection2.Open() aCommand = New OleDbCommand(aQuery3, aConnection2) aDataReader2 = aCommand.ExecuteReader() userID = max + 1 aQuery = "Insert Into UserDetails " aQuery = aQuery & "Values ('" & userID & "','" & userFName & "','" & userLName & "','" & userEmail & "','" & userUsername & "','" & userPassword & "')" aCommand = New OleDbCommand(aQuery, aConnection2) aCommand.ExecuteNonQuery() aConnection2.Close() Else aConnection3 = New OleDbConnection(aConnectionString) aConnection3.Open() aCommand = New OleDbCommand(aQuery2, aConnection3) aDataReader2 = aCommand.ExecuteReader userID = min - 1 aQuery = "Insert Into UserDetails " aQuery = aQuery & "Values ('" & userID & "','" & userFName & "','" & userLName & "','" & userEmail & "','" & userUsername & "','" & userPassword & "')" aCommand = New OleDbCommand(aQuery, aConnection3) aCommand.ExecuteNonQuery() aConnection3.Close() lblResults.Text = "User Account successfully created" btnCreateUser.Enabled = False End If Here's the code I used to get the max and min values from the database. I'm getting a value of 0 for both of them - when min should be 1 and max should be 5 Dim minID As Integer Dim maxID As Integer aQuery2 = "Select Min(UserID) AS '" & [minID] & "' From UserDetails" aQuery3 = "Select Max(UserID) AS ' " & [maxID] & "' From UserDetails"

  • RewriteRule not working do not know how to test it the regex matches

    - by user564559
    Hello I have a Rewrite rule I am trying to implement on my local host but I cannot get it to do the action no matter how I setup the regex the files are in this naming scheme /docroot/css/stylesheet.min.css and I have them printed in the code like /docroot/css/stylesheet.min.123438348.css (the number is example it comes from a get modified function). Note docroot is an example directory how can I have the server ignore the numbers and redirect to the stylesheet.min.css I need to do this for every css and js files (/js and /css) as well as one specific spritemap image my current attempt RewriteRule ^/(docroot)/(js|css)/(.+)\.(min)\.(.+)\.(js|css)$ /$1/$2/$3.$4.$6 RewriteRule ^(/docroot/images/spritemap)\.([0-9]+)\.(png)$ $1.$3 I have this wrapped in a I am on linux..should this be mod_rewrite.so?"
