  • Inserting into a bitstream

    - by evilertoaster
    I'm looking for a way to efficiently insert bits into a bitstream and have it 'overflow', padding with 0's. So for example if you had a byte array with 2 bytes: 231 and 109 (11100111 01101101), and did BitInsert(byteArray,4,00) it would insert two bits at bit offset 4 making 11100001 11011011 01000000 (225,219,24). It would be ok even the method only allowed 1 bit insertions e.g. BitInsert(byteArray,4,true) or BitInsert(byteArray,4,false). I have one method of doing it, but it has to walk the stream with a bitmask bit by bit, so I'm wondering if there's a simpler approach... Answers in assembly or a C derivative would be appreciated.

  • Adding Multiline html content using javascript

    - by pokrate
    Hi, I have created a usercontrol and I want to put its generated html using a javascript file in a webpage. But couldnt do so. Like <script src='file.aspx'></script> should add the html from the usercontrol to the container div. The file "file.aspx" has its content-type set to "text/javascript". And using LoadControl() method I am loading the usercontrol, and then using its RenderControl method, I am able to get its generated html. But I couldnt show it up in the webpage. But I am able to add single line html content , but multiline consumed my whole day :( .

  • System.Diagnostics.Debugger.Debug() stopped working

    - by Andrew Miner
    I'm working on a program which uses the System.Diagnostics.Debugger.Break() method to allow the user to set a breakpoint from the command-line. This has worked fine for many weeks now. However, when I was working on fixing a unit test today, I tried to use the debug switch from the command-line, and it didn't work. Here's what I've tried: I've confirmed that the Debug() method is really being called (by putting a System.Console.WriteLine() after it) I've confirmed that the build is still in Debug I've done a clean build I've restarted Product Studio A quick Google search didn't reveal anything, and the API documentation for .Net doesn't mention anything about this function not performing correctly. So... any ideas?

  • How can I test if a point lies within a 3d shape with its surface defined by a point cloud?

    - by Ben
    Hi I have a collection of points which describe the surface of a shape that should be roughly spherical, and I need a method with which to determine if any other given point lies within this shape. I've previously been approximating the shape as an exact sphere, but this has proven too inaccurate and I need a more accurate method. Simplicity and speed is favourable over complete accuracy, a good approximation will suffice. I've come across techniques for converting a point cloud to a 3d mesh, but most things I have found have been very complicated, and I am looking for something as simple as possible. Any ideas? Many thanks, Ben.

  • Regex for Searching for Text Not Preceeded By a Specific String

    - by James
    Hi, I am working on a web site with several other developers and we have had problems where people commit JavaScript code with AJAX calls that use URL's relative to the site root. An example would be /Home/Index which will not work if the site is hosted in a virtual directory. To get round the problem we use a $.url() method to convert it to a full path, e.g. $("#container").load($.url("/Home/Index")) I am trying to write a unit test that will search each JavaScript file and find places where the $.url method is not being used. The only problem is that I cannot seem to write a regex expression to do this. I have tried the following: (?!\$\.url\()"(/\w*)+" But this does not work. I cannot find a way to say that I don't want the $.url in front. Does anyone know if this is possible? Note that I need regular expressions that are compatible with .NET Thanks.

  • Visual Studio 2010 + Resharper Tools|Options|Environment|Fonts and Colors

    - by Gerard
    About fonts and colors in the VS2010 C# text editor with Resharper installed. In the following method: public void Method() { var lis = new System.Collections.ArrayList(); var exc = new System.NotImplementedException(); } ArrayList gets another color as NotImplementedException in the VS2010 text editor, because I edited the color scheme. What would be the difference in these kinds of types so that the color scheme handles them differently? Note that I have Resharper installed but I also tried almost all Resharper entries. I would like to have the ame color for both, but the color of the NotImplementedException type seems immutable.

  • Python 2.6, 3 abstract base class misunderstanding

    - by Aaron
    I'm not seeing what I expect when I use ABCMeta and abstractmethod. This works fine in python3: from abc import ABCMeta, abstractmethod class Super(metaclass=ABCMeta): @abstractmethod def method(self): pass a = Super() TypeError: Can't instantiate abstract class Super ... And in 2.6: class Super(): __metaclass__ = ABCMeta @abstractmethod def method(self): pass a = Super() TypeError: Can't instantiate abstract class Super ... They both also work fine (I get the expected exception) if I derive Super from object, in addition to ABCMeta. They both "fail" (no exception raised) if I derive Super from list. I want an abstract base class to be a list but abstract, and concrete in sub classes. Am I doing it wrong, or should I not want this in python?

  • How to remove duplicate line in a file

    - by Abs
    Hi I'm using the below method to write to a file from the Jtextarea and I call this method every 30 second within a Timer but instead to add only new line in file it rewrite the entire lines contained in Jtextarea so then I have duplicate lines. I want to avoid this and update the file just with new lines. Could you help me please. public void loger() { FileWriter writer = null; try { writer = new FileWriter("MBM_Log_"+date()+".txt" , true); textArea.write(writer); } catch (IOException exception) { System.err.println("log error"); exception.printStackTrace(); } finally { if (writer != null) { try { writer.close(); } catch (IOException exception) { System.err.println("Error closing writer"); exception.printStackTrace(); } } } }

  • JNI cached jclass global reference variables being garbage collected?

    - by bubbadoughball
    I'm working in the JNI Invocation API, calling into Java from C. I have some upfront initialization to cache 30+ Java classes into global references. The results of FindClass are passed into NewGlobalRef to acquire a global reference to the class. I'm caching these class variables to reuse them later. I have 30+ global references to classes (and 30+ global methodIDs for the class constructors). In the following sample, I've removed exception handling as well as JNI invocation for the purpose of shortening the code snippet. My working code has exception checks after every JNI call and I'm running with -Xcheck:jni. Here's the snippet: jclass aClass; jclass bClass; jmethodID aCtor; jmethodID bCtor; void getGlobalRef(const char* clazz, jclass* globalClass) { jclass local = (*jenv)->FindClass(jenv,clazz); if (local) { *globalClass = (jclass) (*jenv)->NewGlobalRef(jenv,local); (*jenv)->DeleteLocalRef(jenv,local); } } methodID getMethodID(jclass clazz, const char* method, const char* sig) { return (*jenv)->GetMethodID(jenv,clazz,method,sig); } void initializeJNI() { getGlobalRef("MyProj/Testclass1", &aclass); getGlobalRef("MyProj/Testclass2", &bclass); . . aCtor = getMethodID(aclass,"<init>","()V"); bCtor = getMethodID(bclass,"<init>","(I)V"); } The initializeJNI() function sets the global references for jclasses and method IDs for constructors as well as some jfieldID's and some initialization of C data structures. After initialization, when I call into a JNI function using some of the cached jclasses and ctor jmethodIDs, I get a bad global or local reference calling reported from the -Xcheck:jni. In gdb, I break at the last line of initializeJNI(), and print all jclasses and jmethodIDs and the ones causing problems look to have been turned into garbage or garbage-collected (i.e. 0x00 or 0x06). Is it possible for global references to be gc'ed? Any suggestions?

  • resetting the image in an NSView

    - by Josan
    I think this is a very simple question, but I’m new to programming so I may be going about it in a wrong-headed way. I have a basic understanding of Objective-C writing terminal applications and am teaching myself how to use the Cocoa GUI. I understand how to use IBOutlet and IBAction to connect a simple button to a method that will repeatedly send random numbers to a textfield . I understand how to add a NSView file, connect it to a custom view in interface builder and draw a path through random points in the view when the application launches. (I’ve been putting this code inside the - (void)drawRect:(NSRect)dirtyRect method that is declared when the file is created). What I can’t seem to figure out is how to connect a button to an action that will then ‘refresh’ the view – in this case repopulate it with another set of random points connected with a path. Looking at the documentation, I think I should somehow be using – (void) setNeedsDisplay(BOOL)flag but nothing I have tried so far had worked. Please tell me, what am I missing here?

  • Add every value in stack

    - by rezivor
    I am trying to figure out a method that will add every value in a stack. The goal is to use that value to determine if all the values in the stack are even. I have written to code to do this template <class Object> bool Stack<Object>::objectIsEven( Object value ) const { bool answer = false; if (value % 2 == 0) answer = true; return( answer ); } However, I am stumped on how to add all of the stack's values in a separate method

  • How to sum properties of the objects within an array in Ruby

    - by Ernst Fitschen
    I understand that in order to sum array elements in Ruby one can use the inject method, i.e. array = [1,2,3,4,5]; puts array.inject(0, &:+) But how do I sum the properties of objects within an object array e.g. There's an array of objects and each object has a property "cash" for example. So I want to sum their cash balances into one total. Something like... array.cash.inject(0, &:+) (but this doesn't work) I realise I could probably make a new array composed only of the property cash and sum this, but I'm looking for a cleaner method if possible!

  • Programatically WPF Fade In (via extension methods)

    - by Dinis Cruz
    I'm trying to write a simple (stand alone) C# extension method to do a Fade-In of a generic WPF UIElement, but the solutions (and code samples) that I found all contain a large number of moving parts (like setting up a story, etc...) For reference here is an example of the type of API method I would like to create. This code will rotate an UIElement according to the values provided (fromValue, toValue, duration and loop) public static T rotate<T>(this T uiElement, double fromValue, double toValue, int durationInSeconds, bool loopAnimation) where T : UIElement { return (T)uiElement.wpfInvoke( ()=>{ DoubleAnimation doubleAnimation = new DoubleAnimation(fromValue, toValue, new Duration(TimeSpan.FromSeconds(durationInSeconds))); RotateTransform rotateTransform = new RotateTransform(); uiElement.RenderTransform = rotateTransform; uiElement.RenderTransformOrigin = new System.Windows.Point(0.5, 0.5); if (loopAnimation) doubleAnimation.RepeatBehavior = RepeatBehavior.Forever; rotateTransform.BeginAnimation(RotateTransform.AngleProperty, doubleAnimation); return uiElement; }); }

  • Just a small problem regarding javscript BOM question

    - by caramel1991
    The question is this: Create a page with a number of links. Then write code that fires on the window onload event, displaying the href of each of the links on the page. And this is my solution <html> <body language="Javascript" onload="displayLink()"> <a href="http://www.google.com/">First link</a> <a href="http://www.yahoo.com/">Second link</a> <a href="http://www.msn.com/">Third link</a> <script type="text/javascript" language="Javascript"> function displayLink() { for(var i = 0;document.links[i];i++) { alert(document.links[i].href); } } </script> </body> </html> This is the answer provided by the book <html> <head> <script language=”JavaScript” type=”text/javascript”> function displayLinks() { var linksCounter; for (linksCounter = 0; linksCounter < document.links.length; linksCounter++) { alert(document.links[linksCounter].href); } } </script> </head> <body onload=”displayLinks()”> <A href=”link0.htm” >Link 0</A> <A href=”link1.htm”>Link 2</A> <A href=”link2.htm”>Link 2</A> </body> </html> Before I get into the javascript tutorial on how to check user browser version or model,I was using the same method as the example,by acessing the length property of the links array for the loop,but after I read through the tutorial,I find out that I can also use this alternative ways,by using the method that the test condition will evalute to true only if the document.links[i] return a valid value,so does my code is written using the valid method??If it's not,any comment regarding how to write a better code??Correct me if I'm wrong,I heard some of the people say "a good code is not evaluate solely on whether it works or not,but in terms of speed,the ability to comprehend the code,and could posssibly let others to understand the code easily".Is is true??

  • Can't write text into textbox in ASP.NET web app

    - by dotnetdev
    Hi, I have an ASP.NET web application. In the codebehind for the .ascx page (which I embed as below), I attempt to write a string to a textbox in a method like this: Code for embedding control: Control ctrl = Page.LoadControl("/RackRecable.ascx"); PlaceHolder1.Controls.Add(ctrl); Method to make string for inserting into textbox: string AppendDetails() { StringBuilder sb = new StringBuilder(); sb.Append("msg" + " " + textbox1.Text etc etc ); return sb.ToString(); } Called as (in codebehind event handler for button click): this.TextBox4.Text = AppendDetails(); I call it by using ATextBox.Text = AppendDetails (in the button click event handler). The textbox TextBox4 is in the designer file so I am confused why the text does not get written into this textbox (it is readonly and enabled). When stepping through, the textbox4 control will successfully show the text I want it to display in quick watch but not in the actual page, it won't. Any ideas? Thanks

  • Why use event listeners over function calls?

    - by Organiccat
    I've been studying event listeners lately and I think I've finally gotten them down. Basically, they are functions that are called on another object's method. My question is, why create an event listener when calling the function will work just fine? Example, I want to call player.display_health(), and when this is fired, the method player.get_health() should be fired and stored so that display_health() has access to it. Why should I use an event listener over simply calling the function? Even if display_health() were in another object, this still doesn't appear to be a problem to me. If you have another example that fits the usage better, please let me know. Perhaps particular languages don't benefit from it as much? (Javascript, PHP, ASP?)

  • Remove a certain value from string which keeps on changing

    - by user2971375
    I m trying to make a utility to generate a Insert script of sql tables along with relational table. I got all the values in c#. Now I want to remove the one column name and its value from the script.most probably the identity column. Eg. The string I have (which keeps on changing with table name and varies) INSERT Core.Customers ([customerId],[customername],[customeradress],[ordernumber]) Values(123,N'Rahul',N'244 LIZ MORN',2334) NOW I know I have to remove CustomerId. (sometimes need to be replaces with @somevariable) Please give me an efficient way how to retrieve customerId value and Deleting column name and value . Conditions: insert script length and columns names keep changing. Method should return the deleted value. At some point of time customer id can be same as order id. In that case my string.remove method fails.

  • Java HashSet is allowing dupes; problem with comparable?

    - by IVR Avenger
    Hi, all. I've got a class, "Accumulator", that implements the Comparable compareTo method, and I'm trying to put these objects into a HashSet. When I add() to the HashSet, I don't see any activity in my compareTo method in the debugger, regardless of where I set my breakpoints. Additionally, when I'm done with the add()s, I see several duplicates within the Set. What am I screwing up, here; why is it not Comparing, and therefore, allowing the dupes? Thanks, IVR Avenger

  • Using type hints in Clojure for Java return values

    - by mikera
    I'm working on some Java / Clojure interoperability and came across a reflection warning for the following code: (defn load-image [resource-name] (javax.imageio.ImageIO/read (.getResource (class javax.imageio.ImageIO) resource-name))) => Reflection warning, clojure/repl.clj:37 - reference to field read can't be resolved. I'm surprised at this because getResource always returns a URL and I would therefore expect the compiler to use the appropriate static method in javax.imageio.ImageIO/read. The code works fine BTW so it is clearly finding the right method at run time. So two questions: Why is this returning a reflection warning? What type hint do I need to fix this?

  • How to reference an anonymous JavaScript function?

    - by ProfK
    I'm trying to call a Page Method using a jQuery 'attached' event function, in which I like to use the closure to keep the event target local, as below, but page method calls declare several 'error' functions, and I would like to use one function for all of them. If, in the below code, I was handling an error and not success, how could I use my single, anonymous handler for all 3 error functions? $(":button").click(function () { var button = this; PageMethods.DoIt( function (a, b, c) { alert(button); }); }); This example passes an anonymous function for the success callback. There is only one of these. If I was passing an error callback, how could I use 'function (e, c, t)' for all 3 error callbacks?

  • How can I debug or set a break statement inside an expression tree?

    - by Abel
    When an external library contains a LINQ provider, and it throws an exception when executing a dynamic expression tree, how can I break when that expression is thrown? For example, I use a third party LINQ2CRM provider, which allows me to call the Max<TSource, TResult>() method of IQueryable, but when it throws an InvalidCastException, I fail to break on the spot when the exception is thrown, making it hard to review the stack-trace because it's already unwinded when the debugger breaks it in my code. I've set "break on throw" for the mentioned exception. My debug settings are: Clarification on where exactly I'd want to break. I do not want to break in side the LINQ Expression, but instead, I want to break when the expression tree is executed, or, put in other words, when the IQueryable extension method Max() calls the override provided by the LINQ provider. The top of the stacktrace looks like this, which is where I would like to break inside (or step through, or whatever): at XrmLinq.QueryProviderBase.Execute[T](Expression expression) at System.Linq.Queryable.Max[TSource,TResult](IQueryable`1 source, Expression`1 selector)

  • Term for releasing software with time dependant portions still unfinished.

    - by Jeremy French
    I remember a while a go on a SO podcast Jeff was talking about the bounty system and he said that they released the bounty offering code before the bounty awarding code was written as the code would not be needed for a couple of weeks. Is there a standard term for this? Agile can work in this way but it doesn’t have to. I am thinking of suggesting it to a client for something and would like to use the correct terminology along with any information backing it up as a method. Essentially the method is to release code with some functionality incomplete as the time until the incomplete functionality is needed is less that the time it will take to develop.
