  • Visual Studio Add in to Add Tracing

    - by Eric Brown - Cal
    I was looking to write/get a visual studio addin. I want to be able to write descriptive log calls at the top and bottom of a function. like this log.debug("TheClass.TheMethod(string TheStringParam ="+TheStringParam+") - in"); log.debug("TheClass.TheMethod(string TheStringParam ="+TheStringParam+") - out"); Is there an adin that does this? Is there source anywhere for an add in like Ghost Doc that does reflection(or whatever) to parse the parameters and such?

  • Anti-aliased text on HTML5's canvas element

    - by Matt Mazur
    I'm a bit confused with the way the canvas element anti-aliases text and am hoping you all can help. In the following screenshot the top "Quick Brown Fox" is an H1 element and the bottom one is a canvas element with text rendered on it. On the bottom you can see both "F"s placed side by side and zoomed in. Notice how the H1 element blends better with the background: http://jmockups.s3.amazonaws.com/canvas_rendering_both.png Here's the code I'm using to render the canvas text: var canvas = document.getElementById('canvas'); if (canvas.getContext){ var ctx = canvas.getContext('2d'); ctx.fillStyle = 'black'; ctx.font = '26px Arial'; ctx.fillText('Quick Brown Fox', 0, 26); } Is it possible to render the text on the canvas in a way so that it looks identical to the H1 element? And why are they different?

  • AutoScaleMode problems with changed default font

    - by Doc Brown
    Hi, I have some problems with the Form.AutoScaleMode property together with fixed size controls, when using a non-default font. I boiled it down to a simple test application (WinForms 2.0) with only one form, some fixed size controls and the following properties: class Form1 : Form { // ... private void InitializeComponent() { // ... this.AutoScaleDimensions = new System.Drawing.SizeF(96F, 96F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi; this.Font = new System.Drawing.Font("Tahoma", 9.25F); // ... } } Under 96dpi, Windows XP, the form looks correctly like this 96 dpi example. Under 120 dpi, Windows XP, the the Windows Forms autoscaling feature produces this 120 dpi example. As you can see, groupboxes, buttons, list or tree views are scaled correctly, multiline text boxes get too big in the vertical axis, and a fixed size label does not scale correctly in both vertical and horizontal direction. Seems to be bug in the .NET framework? Using the default font (Microsoft Sans Serif 8.25pt), this problem does not occur. Using AutoScaleMode=Font (with adequate AutoScaleDimensions, of course) either does not scale at all or scales exactly like seen above, depending on when the Font is set (before or after the change of AutoScaleMode). The problem is not specific to the "Tahoma" Font, it occurs also with Microsoft Sans Serif, 9.25pt. And yes, i already read this SO post http://stackoverflow.com/questions/2114857/high-dpi-problems but it does not really help me. Any suggestions how to come around this? EDIT: I changed my image hoster, hope this one works better. EDIT2: Some additional information about my intention: I have about 50 already working fixed size dialogs with several hundreds of properly placed, fixed size controls. They were migrated from an older C++ GUI framework to C#/Winforms, that's why they are all fixed-size. All of them look fine with 96 dpi using a 9.25pt font. Under the old framework, scaling to 120 dpi worked fine - all fixed size controls scaled equal in both dimensions. Last week, we detected this strange scaling behaviour under WinForms when switching to 120 dpi. You can imagine that most of our dialogs now look very bad under 120 dpi. We are looking for a solution that avoids a complete redesign all those dialogs.

  • How do I create a custom python interpreter? i.e. with certain modules already included?

    - by Johnny Brown
    If you've used Ruby on Rails, I'm thinking of the feature where the user types 'rails console' and instantly gets a Ruby console with rails and the current app already loaded. I want to make something like this for a python program I'm working on, does anyone know how I would get to type say, 'python myPythonConsole.py' and open up a regular python interpreter but with my program and all its dependencies loaded?

  • Using nullable types in C#

    - by Martin Brown
    I'm just interested in people's opinions. When using nullable types in C# what is the best practice way to test for null: bool isNull = (i == null); or bool isNull = !i.HasValue; Also when assigning to a non-null type is this: long? i = 1; long j = (long)i; better than: long? i = 1; long j = i.Value;

  • Object as an array

    - by owca
    I need to create class Dog and PurebredDog extending Dog. Problem is that Dog can be at once single object and array of objects (Dogs and PurebreedDogs : Dog pack[]={new Dog(76589,"As","black",18, "Ann","Kowalsky"), new PurebreedDog(45321,"Labrador","Elf","black",25, "Angus","Mati","Barbara","Smith"), new Dog(102467,"Gamma","brown",89, "Josh","Coke"), new PurebreedDog(9678,"York","Theta","brown",8, "Emka","Figaro","Alice","Cat")}; for(int i=0; i < pack.length; i++) System.out.println(pack[i]+"\n\n"); How to write proper constructor for Dog ?

  • Wait for function to finish before starting again.

    - by Matthew Brown
    Good Morning, I am trying to call the same function everytime the user presses a button. Here is what happens at the moment.. User clicks button - Calls function - function takes 1000ms+ to finish (due to animation with jQuery and AJAX calls) What I want to happen is every time the user presses the button it adds the function to the queue, waits for the previous call to finish, and then starts.. Is this possible? Sorry if my explanation is a bit confusing.. Thanks Matthew

  • Rational Application Developer (RAD) 7.5+ and websphere runtime will not pick up jars from projects

    - by Berlin Brown
    With RAD Version: 7.5.3, Java 1.5. I have a couple of different projects. I needed to break out the java code and turn the *.class files into a jar. So basically, same *.class files I just removed the code and then jarred the class files into a jar. I broke the classes into a jar and then included the jar in the project. And I also did an order/export on the jar so that other projects can see the jar. At this point, ideally my project should not have changed because I am using class files in a jar instead of the java code. When I visit my web application in websphere, I get class not found errors on the classes that are now in the jar. Project Structure: A. Project earApp -- will need the webapp B. Project webapp -- will need the project (no jar files or *.java files are found in this project) C. Project javasrc -- the java source and the NEW JAR file are found here. I don't think websphere is acknowledging the jar. Here is the error: java.lang.NoClassDefFoundError: com.MyApp at java.lang.ClassLoader.defineClassImpl(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:258) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:151) at com.ibm.ws.classloader.CompoundClassLoader._defineClass(CompoundClassLoader.java:675) at com.ibm.ws.classloader.CompoundClassLoader.findClass(CompoundClassLoader.java:614) at com.ibm.ws.classloader.CompoundClassLoader.loadClass(CompoundClassLoader.java:431) at java.lang.ClassLoader.loadClass(ClassLoader.java:597) at java.lang.Class.getDeclaredMethodsImpl(Native Method) at java.lang.Class.getDeclaredMethods(Class.java:664) at com.ibm.ws.webcontainer.annotation.data.ScannedAnnotationData.collectMethodAnnotations(ScannedAnnotationData.java:130) at com.ibm.ws.webcontainer.annotation.data.ScannedAnnotationData.<init>(ScannedAnnotationData.java:47) at com.ibm.ws.webcontainer.annotation.AnnotationScanner.scanClass(AnnotationScanner.java:61) at com.ibm.ws.wswebcontainer.webapp.WebApp.processRuntimeAnnotationHelpers(WebApp.java:711) at com.ibm.ws.wswebcontainer.webapp.WebApp.populateJavaNameSpace(WebApp.java:624) at com.ibm.ws.wswebcontainer.webapp.WebApp.initialize(WebApp.java:289) at com.ibm.ws.wswebcontainer.webapp.WebGroup.addWebApplication(WebGroup.java:93) at com.ibm.ws.wswebcontainer.VirtualHost.addWebApplication(VirtualHost.java:162) at com.ibm.ws.wswebcontainer.WebContainer.addWebApp(WebContainer.java:671) at com.ibm.ws.wswebcontainer.WebContainer.addWebApplication(WebContainer.java:624) at com.ibm.ws.webcontainer.component.WebContainerImpl.install(WebContainerImpl.java:395) at com.ibm.ws.webcontainer.component.WebContainerImpl.start(WebContainerImpl.java:611) at com.ibm.ws.runtime.component.ApplicationMgrImpl.start(ApplicationMgrImpl.java:1274) at com.ibm.ws.runtime.component.DeployedApplicationImpl.fireDeployedObjectStart(DeployedApplicationImpl.java:1165) at com.ibm.ws.runtime.component.DeployedModuleImpl.start(DeployedModuleImpl.java:587) at com.ibm.ws.runtime.component.DeployedApplicationImpl.start(DeployedApplicationImpl.java:832) at com.ibm.ws.runtime.component.ApplicationMgrImpl.startApplication(ApplicationMgrImpl.java:921) at com.ibm.ws.runtime.component.ApplicationMgrImpl$AppInitializer.run(ApplicationMgrImpl.java:2124) at com.ibm.wsspi.runtime.component.WsComponentImpl$_AsynchInitializer.run(WsComponentImpl.java:342) at com.ibm.ws.util.ThreadPool$Worker.run(ThreadPool.java:1497) What do you think I need to do?

  • Automatically support new changes with Python.

    - by Zachary Brown
    I was working on a program,that I need to support new additions. Hmmm. Let me give you some background on the program. It is an educational software program that has quizzes for the user to take, just to gain odd knowledge. Now, It currently supports 6 subjects, all organized with directores on the HDD ( i.e. the Science directory is called science. ) and the way you launch the subject to see what quizzes you have to take is by pushing a button on the home screen. This sort of thing prevents easy subject additions. I want to be able to add a subject later on without having to recode the home screen and re organize all the buttons. I would use a Listbox and os.listdir(...), but I was kind of wanting something prettier than a Listbox. I am using Tkinter on Windows. The Python version I am using is 2.6 Is there a "fancy" listbox sort of thing that can be styled to work with the background?

  • Porting a piece of Lisp code to Clojure (PAIP)

    - by Robert Brown
    I'm reading Paradigms of Artificial Intelligence Programming (PAIP) by Peter Norvig and I'm trying to write all the code in Clojure rather than common Lisp. However I'm stuck on this piece of code on page 39: (defparameter *simple-grammar* '((sentence -> (noun-phrase verb-phrase)) (noun-phrase -> (Article Noun)) (verb-phrase -> (Verb noun-phrase)) (Article -> the a) (Noun -> man ball woman table) (Verb -> hit took saw liked)) "A grammar for a trivial subset of English.") (defvar *grammar* *simple-grammar*) How can I translate this into Clojure? Thanks.

  • Fuzzy string matching algorithm in Python

    - by Mridang Agarwalla
    Hi guys, I'm trying to find some sort of a good, fuzzy string matching algorithm. Direct matching doesn't work for me — this isn't too good because unless my strings are a 100% similar, the match fails. The Levenshtein method doesn't work too well for strings as it works on a character level. I was looking for something along the lines of word level matching e.g. String A: The quick brown fox. String B: The quick brown fox jumped over the lazy dog. These should match as all words in string A are in string B. Now, this is an oversimplified example but would anyone know a good, fuzzy string matching algorithm that works on a word level. Thanks in advance.

  • What's wrong with my regex

    - by Tom Brown
    Yes I know its usually a bad idea to parse HTML using RegEx, but that aside can someone explain the fault here: string outputString = Regex.Replace(inputString, @"<?(?i:script|embed|object|frameset|frame|iframe|metalink|style|html|img|layer|ilayer|meta|applet)(.|\n)*?>", ""); if (outputString != inputString) { Console.WriteLine("unwanted tags detected"); } It certainly detects the intended tags like: <script> and <html>, but it also rejects strings I want to allow such as <B>Description</B> and <A href="http://www.mylink.com/index.html">A Link containing 'HTML'</A>

  • How to transform phrases and words into MD5 hash?

    - by brilliant
    Can anyone, please, explain to me how to transform a phrase like "I want to buy some milk" into MD5? I read Wikipedia article on MD5, but the explanation given there is beyond my comprehension: "MD5 processes a variable-length message into a fixed-length output of 128 bits. The input message is broken up into chunks of 512-bit blocks (sixteen 32-bit little endian integers)" "sixteen 32-bit little endian integers" is already hard for me. I checked the article on little endians and didn't understand a bit. However, the examples of some phrases and their MD5 hashes are very nice: MD5("The quick brown fox jumps over the lazy dog") = 9e107d9d372bb6826bd81d3542a419d6 MD5("The quick brown fox jumps over the lazy dog.") = e4d909c290d0fb1ca068ffaddf22cbd0 Can anyone, please, explain to me how this MD5 algorithm works on some very simple example? And also, perhaps you know some software or a code that would transform phrases into their MD5. If yes, please, let me know.

  • WinForms: finding the size of a minimized form without going to FormWindowState.Normal

    - by Doc Brown
    Is there an easy way to determine the size of a Form it does have in WindowState=Normal, without actually changing the Form state? Here is what I do now (C# code): public class MyForm: Form { public void MyMethod() { // ... FormWindowState oldState = this.WindowState; this.WindowState = FormWindowState.Normal; Point windowLocation = this.Location; Size windowSize = this.Size; this.WindowState = oldState; // ... } } This is what I would like the code to look like: public class MyForm: Form { public void MyMethod() { // no state change here Point windowLocation = this.NormalStateLocation; Size windowSize = this.NormalStateSize; } } In fact there are no NormalStateLocation or NormalStateSize properties in Windows Forms.

  • Algorithm for disordered sequences of strings

    - by Kinopiko
    The Levenshtein distance gives us a way to calculate the distance between two similar strings in terms of disordered individual characters: quick brown fox quikc brown fax The Levenshtein distance = 3. What is a similar algorithm for the distance between two strings with similar subsequences? For example, in quickbrownfox brownquickfox the Levenshtein distance is 10, but this takes no account of the fact that the strings have two similar subsequences, which makes them more "similar" than completely disordered words like quickbrownfox qburiocwknfox and yet the completely disordered version has a Levenshtein distance of eight. What distance measures exist which take the length of subsequences into account, without assuming that the subsequences can be easily broken into distinct words?

  • ExpressionEngine: {exp:query} producing error

    - by Josh Brown
    Hi. I have this code in place to pull some relation data from the database based on a ID of another weblog entry. The relationship custom field would not work for my situation. I have tested the SQL with MySQL and get no errors. But I get an error when I pull up the page. {exp:query sql="SELECT entry_id,field_id_16,field_id_19 FROM exp_weblog_data WHERE field_id_15='2' AND weblog_id='6'"} Also, I want to populate the “field_id_15” from the url. I have tried using the “segment_*” tag, but nothing. Maybe it is something else. Any help is greatly appreciated. Thanks, Josh

  • Codeigniter: Make field increase by 1 up to a number?

    In my validation class I have this: $fields['a_1'] = 'First Question'; $fields['a_2'] = 'Second Question'; $fields['a_3'] = 'Third Question'; $fields['a_4'] = 'Fourth Question'; This is getting old--I have about 40 of these to write, and each set has matching validation rules: $rules['a_1'] = 'hour'; $rules['a_2'] = 'hour'; ... Is there a way to say: $fields['a_' . 1 - 17] = "One, Two" Etc... Just curious... if not, I'll brute force it.

  • Opening XNA Xbox 360 assemblies in Reflector

    - by David Brown
    I'd like to get a look at the differences between the Xbox 360 and Windows XNA assemblies. I know the 360 runs the .NET Compact Framework and I was under the impression that Reflector could read CF assemblies, but when I open them, all of the methods are blank and no internal classes are shown. Is this done on purpose, or is it a limitation of Reflector? Is there another way to see how the Xbox 360 XNA assemblies work?
