  • change/part doesn't work as expected with parse

    - by Rebol Tutorial
    According to http://www.rebol.com/docs/core23/rebolcore-15.html You can use change/part to parse and replace but that doesn't work well with this where I just try to replace the block <mytag > ... </mytag> by "MyString" content: {<mytag id="a" 111111111111111> </mytag> aaaaaaaaaaaaaaa aaaaaaaaaaaaaaa <mytag id="b" 22222222222222222> </mytag> <mytag id="c" 3333333333333> </mytag> aaaaaaaaaaaaaaa aaaaaaaaaaaaaaa <mytag id="d" 444444444444444> </mytag> } mytag: [ to {<mytag} start: ( ) thru {<mytag} to {id="} thru {id="} copy ID to {"} thru {"} to {</mytag>} thru {</mytag>} ending: (change/part start "mystring" ending) mark: ( write clipboard:// mark input) ] rule: [any mytag to end] parse content rule

  • Approximate photo of a simple drawing using lines

    - by user3704596
    As an input I have a photo of a simple symbol, e.g.: https://www.dropbox.com/s/nrmsvfd0le0bkke/symbol.jpg I would like to detect the straight lines in it, like points of start and ends of the lines. In this case, assuming the top left of the symbol is (0,0), the lines would be defined like this: start end (coordinates of beginning and end of a line) 1. (0,0); (0,10) (vertical line) 2. (0,10); (15, 15) 3. (15,15); (0, 20) 4. (0,20); (0,30) How can I do it (pereferably using OpenCV)? I though about Hough lines, but they seem to be good for perfect thin straight lines, which is not the case in a drawing. I'll probably work on binarized image, too.

  • rails rollback updates when task fails

    - by ash34
    Hi, I have the following "generate_report" method being called from a rake task, which gets a hash as an input, that contains the reported hours spent by each user on a task and outputs the data as a .csv report. desc "Task reporting" task :report, [:inp_dt] => [:environment] do |t, args| h = select_data(args.inp_dt) /* not shown here */ generate_report(h) end def generate_report(h) out_dir = File.dirname(__FILE__) + '/../../output' myfile = "#{out_dir}" + "/monthly_#{Date.today.strftime("%m%d%Y")}.csv" writer = CSV.open(myfile, 'w') h.each do |h,v| v.each do |key,val| writer << val end end writer.close end where h = {:BILL=>{:PROJA=>["CYR", "00876", "2", 24], :PROJB=>["EPR", "00876", "2", 16]}, :JANE=>{:PROJA=>["TRB", "049576", "2", 16]}} I would like to set/update a 'processed' flag for each reported transaction and only commit the update when the file is written correctly or rollback the updates when the task fails. How can I accomplish this. thanks, ash

  • What is an alternative to ADO.NET, but elegant way in C# to read Excel files

    - by Khnle
    ADO.NET just fails miserably when it's used to read Excel files where a column contains mixed data types. It appears that it tries to determine the data type of a column, and then assume the rest of the entire column is of the same data type. Here are some backgrounds: http://stackoverflow.com/questions/2968111/how-to-prevent-ado-net-from-altering-double-values-when-it-reads-from-excel-files http://blog.lab49.com/archives/196 What is an alternative approach that doesn't require automation, Excel to be co-installed, is simple (since the input excel file will only have one worksheet in each file).

  • Javascript form validation events

    - by user307922
    Hi All, I am making a small form for a php app and had a question regarding javascript validation. What is the best event to run the javascript validation on the input value? Is it the "focusout" event? I used "focusout" to originally but it creates problems when the user hits enter while they are still focused on any particular field in the form. Should I run the js validation when the user clicks submit? Just looking for some advice. Thanks! Chuck

  • Serving large generated files using Google App Engine?

    - by John Carter
    Hiya, Presently I have a GAE app that does some offline processing (backs up a user's data), and generates a file that's somewhere in the neighbourhood of 10 - 100 MB. I'm not sure of the best way to serve this file to the user. The two options I'm considering are: Adding some code to the offline processing code that 'spoofs' it as a form upload to the blob store, and going thru the normal blobstore process to serve the file. Having the offline processing code store the file somewhere off of GAE, and serving it from there. Is there a much better approach I'm overlooking? I'm guessing this is functionality that isn't well suited to GAE. I had thought of storing in the datastore as db.Text or Dd.Blob but there I encounter the 1 MB limit. Any input would be appreciated,

  • Java generics question

    - by user247866
    So I have 3 classes. Abstract class A Class B extends class A independent Class C In class D that contains the main method, I create a list of instances of class B List<B> b = methodCall(); // the method returns a list of instances of class B Now in class C I have one method that is common to both A and B, and hence I don't want to duplicate it. I want to have one method that takes as input an instance of class A, as follows: public void someMethod(List<A> a) However, when I do: C c = new C(); c.someMethod(b); I get an error that some-method is not applicable for the argument List<B>, instead it's expecting to get List<A>. Is there a good way to fix this problem? Many thanks!

  • How can a string timestamp with hours 0 to 24 be parsed

    - by user897052
    I am trying to parse a string timestamp of format "yyyyMMddHHmmss" with DateTime.ParseExact(). The catch is I must allow for an hour value of "24" (i.e. hours can be from 0 to 24; Note: I can't control the input values.) and, of course, that results in an exception. Are there any settings/properties I can set instead of manually parsing/using regex's? If not, any efficient parsing ideas? ex. DateTime.ParseExact("20120911240000", "yyyyMMddHHmmss", System.Globalization.CultureInfo.InvariantCulture); hour 24 means hour 0 of next day (so day + 1, hour = 0)

  • Submit jQuery UI dialog on <Enter>

    - by CMB
    I have a jQuery UI dialog box with a form. I would like to simulate a click on one of the dialog's buttons so you don't have to use the mouse or tab over to it. In other words, I want it to act like a regular GUI dialog box where simulates hitting the "OK" button. I assume this might be a simple option with the dialog, but I can't find it in the jQuery UI documentation. I could bind each form input with keyup() but didn't know if there was a simpler/cleaner way. Thanks.

  • 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 ?

  • Adding a textblock to a custom wpf control (piepiece control from codeplex)

    - by bomortensen
    Hi Stackoverflow! I'm currently building a Surface application where the main navigation is a circular menu. For each menu item I'm using a custom control that I found on codeproject.com: http://www.codeproject.com/KB/WPF/PieChartDataBinding.aspx (PiePiece control) The number of submenu items (which is also piepiece controls) comes from a database and thus dynamically loaded. What I can't figure out is how I add a textblock to this custom control to display the submenu item text. It needs to follow the PiePiece's RotationAngle property to line up correctly. Anyone got a hot-fix for this? I was thinking about adding another dependencyproperty to the piepiece custom control, but that way I can't set the font-family, size etc (can I?) Any input on this is greatly appreciated! Thanks!

  • DecimalFormat and Double.valueOf()

    - by folone
    Hello. I'm trying to get rid of unnecessary symbols after decimal seperator of my double value. I'm doing it this way: DecimalFormat format = new DecimalFormat("#.#####"); value = Double.valueOf(format.format(41251.50000000012343)); But when I run this code, it throws: java.lang.NumberFormatException: For input string: "41251,5" at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:1224) at java.lang.Double.valueOf(Double.java:447) at ... As I see, Double.valueOf() works great with strings like "11.1", but it chokes on strings like "11,1". How do I work around this? Is there a more elegant way then something like Double.valueOf(format.format(41251.50000000012343).replaceAll(",", ".")); Is there a way to override the default decimal separator value of DecimalFormat class?

  • Developing and deploying games for Windows, Mac (& Linux)

    - by nornagon
    I want to write games that run on all the major platforms. I also want people to be able to play them by downloading a file and double clicking it. That means a single .exe/.app file. I'm happy to use OpenGL directly for graphics. What I don't know how to do is show a window, handle mouse/keyboard input and play sounds in a cross-platform manner. I don't really mind what the underlying language is, as long as it isn't C++ or Java. C#, Ruby or Python would be preferable, in that order :) Please, SO, save me from having to write Flash games!

  • How do I post dynamic information to Facebook from Flash?

    - by daidai
    I am building a Flash site and I want to be able to allow the user to post dynamically produced information to their Facebook wall, but I can't find out any information within the Facebook developers documentation. Its simple enough in Javascript/HTML: <script type="text/javascript"> function callPublish(msg, attachment, action_link) { FB.ensureInit(function () { FB.Connect.streamPublish('', attachment, action_link); }); } </script> <input type="button" onclick="callPublish('',{'name':'Post this to Facebook','href':'http://dev2.com','description':'this is some body test'},null);return false;" value="Preview Dialog" /> As you can see I don't want to create sessions or login or anything complicated, just post to info to their wall.

  • Is there a way to make XmlDocument parsing less strict

    - by Istrebitel
    I am making a program that will store its data in an XML file. When people write XML they can make subtle mistakes, like ending a comment with - so it looks like <!-- comment ---> or adding a </>inside an attribute. Naturally, the XML still can be read all right, but trying to input this text into XmlDocument will give a syntax error (and it wont be parsed). Is there a way to make XmlDocument less strict and make it ignore violations of the standard that do not make the document unparseable? For example, its clear that <!-- comment ---> is still a comment even though it contains - at the end which is against the standard specification).

  • Tag Cloud Data Backend

    - by Waldron
    I want to be able to generate tag clouds from free text that comes from any number of different sources. For clarity, I'm not talking about how to display a tag cloud once the critical tags/phrases are already discovered, I'm hoping to be able to discover the meaningful phrases themselves... preferable on a PHP/MySQL stack. If I had to do this myself, I'd start by establishing some kind of index for words/phrases that gives a "normal" frequency for any word/phrase. eg "Constantinople" occurs once in every 1,000,000 words on average (normal frequency "0.000001"). Then as I analyze a body of text, I'd find the individual words/phrases (another challenge!), find frequencies of each within the input, and measure against the expected freqeuncy. Words that have the highest ratio against expected frequency get boosted priority in the cloud. I'd like to believe someone else has already done this, WAY better than I could hope to, but I'll be damned if I can find it. Any recommendations??

  • dropping user to IRB after reading from pipe

    - by aurelian
    I have this script that drops the user to an IRB session when executed. All good, but when I use *nix pipes to get the input (e.g. with cat), the IRB session ends immediately. I could reduce the script (let's call it myscript.rb) to the following: require 'irb' if $stdin.stat.size 0 @text = $stdin.read else @text= "nothing" end ARGV.clear IRB.start When executed like: ruby myscript.rb, I end up in the IRB session (as expected). But (assuming foo.txt exists in the cwd): cat foo.txt | ruby myscript.rb will just print the IRB prompt and then the IRB session is closed (I'm being dropped to $bash). Any known workarounds or ideas? BTW: it has the same behavior on ruby 1.8.7 as well as on 1.9.2.

  • C# VS 2008 Build Configurations - using different classes for different builds

    - by evan
    I'm writing an application which has two classes that provide basically the same functionality but for different situations. I'd like to have three versions of the software - one where the user can change an ini file to configure the program to use one of the two classes, and then one version that only uses one of the two classes. Right now I have it working via an ini file, but I'd like to be able to build versions that don't include the code for the unneeded class at all. What is the best way to go about this? My current line of thinking is that since both classes derive from a common interface I'll just add a compile time conditional that looks at the active build configuration and decides whether to compile that class. What is the syntax to do that? Thanks in advance for your help and input!

  • Makefile option/rule to handle missing/removed source files

    - by b3nj1
    http://stackoverflow.com/questions/239004/need-a-makefile-dependency-rule-that-can-handle-missing-files gives some pointers on how to handle removed source files for generating .o files. I'm using gcc/g++, so adding the -MP option when generating dependencies works great for me, until I get to the link stage with my .a file... What about updating archives/libraries when input sources go away? This works OK for me, but is there a cleaner way (ie, something as straightforward as the g++ -MP option)? #BUILD_DIR is my target directory (includes Debug/Release and target arch) #SRC_OUTS are my .o files LIBATLS_HAS = $(shell nm ${BUILD_DIR}/libatls.a | grep ${BUILD_DIR} | sed -e 's/.*(//' -e 's/).*://') LIBATLS_REMOVE = $(filter-out $(notdir ${SRC_OUTS}), ${LIBATLS_HAS}) ${BUILD_DIR}/libatls.a: ${BUILD_DIR}/libatls.a(${SRC_OUTS}) ifneq ($(strip ${LIBATLS_REMOVE}),) $(AR) -d $@ ${LIBATLS_REMOVE} endif

  • Function not recognized from jQuery

    - by coffeeaddict
    I've got a .js file that has this function in it: function showDialog(divID) { var dialogDiv = $(divID); dialogDiv.dialog ( { bgiframe: true, modal: true, autoOpen: false, show: 'blind' } ) And in my page this: <script type="text/javascript"> $(function() { $("input.invokeDialog").click.showDialog("#testDialog"); }); </script> I'm trying to figure out why it doesn't recognize my showDialog function. Is it not possible to reference it with the dot as I am doing? Do I need a jQuery specific function or syntax for it to know that it's a jQuery function or is there no such thing?
