  • How can I count paragraphs in text file using Perl?

    - by robjez
    I need to create Perl code which allows counting paragraphs in text files. I tried this and doesn't work: open(READFILE, "<$filename") or die "could not open file \"$filename\":$!"; $paragraphs = 0; my($c); while($c = getc(READFILE)) { if($C ne"\n") { $paragraphs++; } } close(READFILE); print("Paragraphs: $paragraphs\n");

  • How can I make these images download on a seperate thread?

    - by Andy Barlow
    Hello!! I have the following code running on my Android device. It works great and displays my list items wonderfully. It's also clever in the fact it only downloads the data when it's needed by the ArrayAdapter. However, whilst the download of the thumbnail is occurring, the entire list stalls and you cannot scroll until it's finished downloading. Is there any way of threading this so it'll still scroll happily, maybe show a place holder for the downloading image, finish the download, and then show? Any help with this would be really apreciated. Thank-you kindly. Andy Barlow private class CatalogAdapter extends ArrayAdapter { private ArrayList<SingleQueueResult> items; //Must research what this actually does! public CatalogAdapter(Context context, int textViewResourceId, ArrayList<SingleQueueResult> items) { super(context, textViewResourceId, items); this.items = items; } /** This overrides the getview of the ArrayAdapter. It should send back our new custom rows for the list */ @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.mylists_rows, null); } final SingleQueueResult result = items.get(position); // Sets the text inside the rows as they are scrolled by! if (result != null) { TextView title = (TextView)v.findViewById(R.id.mylist_title); TextView format = (TextView)v.findViewById(R.id.mylist_format); title.setText(result.getTitle()); format.setText(result.getThumbnail()); // Download Images ImageView myImageView = (ImageView)v.findViewById(R.id.mylist_thumbnail); downloadImage(result.getThumbnail(), myImageView); } return v; } } // This should run in a seperate thread public void downloadImage(String imageUrl, ImageView myImageView) { try { url = new URL(imageUrl); URLConnection conn = url.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); BufferedInputStream bis = new BufferedInputStream(is); Bitmap bm = BitmapFactory.decodeStream(bis); bis.close(); is.close(); myImageView.setImageBitmap(bm); } catch (IOException e) { /* Reset to Default image on any error. */ //this.myImageView.setImageDrawable(getResources().getDrawable(R.drawable.default)); } }

  • Thin-border on WPF window?

    - by Rezzie
    I'd like to create a window, using WPF, that has a thin border all the way around the form - i.e. no space for the title bar with the icon/caption and min/max/close buttons. For example, the "extra" icons form of the new Windows 7 taskbar: How can I do this with WPF (I don't mind resorting to the Win32 API, if not supported natively by WPF)?

  • How can i use a duration setting on .animate if it is inside the callback from a .fadeOut effect?

    - by Jannis
    I am trying to just fade the content of section#secondary out and once the content has been faded out, the parent (section#secondary) should animate 'shut' in a slider animation. All this is working however the durations are not and I cannot figure out why. Here is my code: HTML <section id="secondary"> <a href="#" class="slide_button">&laquo;</a> <!-- slide in/back button --> <article> <h1>photos</h1> <div class="album_nav"><a href="#">photo 1 of 6</a> | <a href="#">create an album</a></div> <div class="bar"> <p class="section_title">current image title</p> </div> <section class="image"> <div class="links"> <a class="_back album_link" href="#">« from the album: james new toy</a> <nav> <a href="#" class="_back small_button">back</a> <a href="#" class="_next small_button">next</a> </nav> </div> <img src="http://localhost/~jannis/3781_doggie_wonderland/www/preview/static/images/sample-image-enlarged.jpg" width="418" height="280" alt="" /> </section> </article> <footer> <embed src="http://localhost/~jannis/3781_doggie_wonderland/www/preview/static/flash/secondary-footer.swf" wmode="transparent" width="495" height="115" type="application/x-shockwave-flash" /> </footer> </section> <!-- close secondary --> jQuery // ============================= // = Close button (slide away) = // ============================= $('a.slide_button').click(function() { $(this).closest('section#secondary').children('*').fadeOut('slow', function() { $('section#secondary').animate({'width':'0'}, 3000); }); }); Because the content of section#secondary is variable I use the * selector. What happens is that the fadeOut uses the appropriate slow speed but as soon as the callback fires (once the content is faded out) the section#secondary animates to width: 0 within a couple of milliseconds and not the 3000 ms ( 3 sec ) I set the animation duration to. Any ideas would be appreciated. PS: I cannot post an example at this point but since this is more a matter of theory of jQuery I don't think an example is necessary here. Correct me if I am wrong..

  • IE image map remains clickable behind another div

    - by Ryan Giglio
    I have an Image Map of the United States. When you click on a state, the map fades out and a map of that state appears with an image map of the area codes in the state. In Firefox, Safari, and Chrome, the state map becomes clickable and the United States map becomes unclickable until you close the sate popover. However in Internet Explorer, the United States map remains clickable through the state popover, and I cannot click on any area codes. Here is my javascript: $(document).ready(function() { $("#usMap").html(); $("#usMap").load("/includes/us_map.inc"); }); $('area').live('click', function() { var state = $(this).attr("class"); var statePopover = $("<div id='statePopoverContainer'><a id='popoverCloseButton'>Close State</a><div id='statePopover'></div></div>"); $("#usMap").append(statePopover); $("#usMapImage").fadeTo('slow', 0.2); $("#statePopover").load("/includes/stateMaps/" + state + ".html"); }); $("#popoverCloseButton").live('click', function() { $("#statePopoverContainer").remove(); $("#usMapImage").fadeTo('slow', 1); }); I am loading the map on document ready because if you don't have Javascript, something else appears. And here is the CSS for all things related: div#usMap { width:676px; height:419px; text-align: center; position: relative; background-color:#333333; z-index: 1; } img#usMapImage { z-index: 1; } area { cursor: pointer; } div#statePopoverContainer { width:100%; height:100%; z-index:5; position:absolute; top:0; left:0; } a#popoverCloseButton { position:absolute; right:0; padding-right:5px; padding-top:5px; color:#FFFFFF; cursor:pointer; } You can see this happening at http://dev.crewinyourcode.com/ Login with beta/tester

  • PHP Calculating future date by adding days to a variable date

    - by OneNerd
    I was looking at this post, and it is close to what I need: http://stackoverflow.com/questions/1669165/php-how-to-count-60-days-from-the-add-date However, in that post, the calculation is performed by adding 60 days to the current date. What I need to do is calculate the date based on a variable date (and not the current date). Something like this: $my_date = $some_row_from_a_database; $date_plus_10_days = ???; Anyone know how to do that? Thanks

  • Getting A File's Mime Type In Java

    - by Lee Theobald
    I was just wondering how most people fetch a mime type from a file in Java? So far I've tried two utils: JMimeMagic & Mime-Util. The first gave me memory exceptions, the second doesn't close its streams off properly. I was just wondering if anyone else had a method/library that they used and worked correctly?

  • Optimizing Haskell code

    - by Masse
    I'm trying to learn Haskell and after an article in reddit about Markov text chains, I decided to implement Markov text generation first in Python and now in Haskell. However I noticed that my python implementation is way faster than the Haskell version, even Haskell is compiled to native code. I am wondering what I should do to make the Haskell code run faster and for now I believe it's so much slower because of using Data.Map instead of hashmaps, but I'm not sure I'll post the Python code and Haskell as well. With the same data, Python takes around 3 seconds and Haskell is closer to 16 seconds. It comes without saying that I'll take any constructive criticism :). import random import re import cPickle class Markov: def __init__(self, filenames): self.filenames = filenames self.cache = self.train(self.readfiles()) picklefd = open("dump", "w") cPickle.dump(self.cache, picklefd) picklefd.close() def train(self, text): splitted = re.findall(r"(\w+|[.!?',])", text) print "Total of %d splitted words" % (len(splitted)) cache = {} for i in xrange(len(splitted)-2): pair = (splitted[i], splitted[i+1]) followup = splitted[i+2] if pair in cache: if followup not in cache[pair]: cache[pair][followup] = 1 else: cache[pair][followup] += 1 else: cache[pair] = {followup: 1} return cache def readfiles(self): data = "" for filename in self.filenames: fd = open(filename) data += fd.read() fd.close() return data def concat(self, words): sentence = "" for word in words: if word in "'\",?!:;.": sentence = sentence[0:-1] + word + " " else: sentence += word + " " return sentence def pickword(self, words): temp = [(k, words[k]) for k in words] results = [] for (word, n) in temp: results.append(word) if n > 1: for i in xrange(n-1): results.append(word) return random.choice(results) def gentext(self, words): allwords = [k for k in self.cache] (first, second) = random.choice(filter(lambda (a,b): a.istitle(), [k for k in self.cache])) sentence = [first, second] while len(sentence) < words or sentence[-1] is not ".": current = (sentence[-2], sentence[-1]) if current in self.cache: followup = self.pickword(self.cache[current]) sentence.append(followup) else: print "Wasn't able to.

  • Create multiple modal windows with javascript (+jQuery), what is the best practice to indentify wind

    - by Kirzilla
    Hello, When creating every instance of Window object I should bind close button of each window to closing this window. But how should I identify windows? Should I create unique id for each Window instance or maybe another way? What is the best way to create such identifiers, maybe some kind of singleton object with id parameter which should be incremented each time when window is created? Thank you.

  • Problem inserting JavaScript into a CKEditor Instance running inside a jQuery-UI Dialog Box

    - by PlasmaFlux
    Hello Overflowers! Here's what's going on: I'm building an app (using PHP, jQuery, etc), part of which lets users edit various bits of a web page (Header, Footer, Main Content, Sidebar) using CKEditor. It's set up so that each editable bit has an "Edit Content" button in the upper right that, on click, launches an instance of CKEditor inside a jQuery-UI Dialog box. After the user is done editing, they can click an 'Update Changes' button that passes the edited content back off to the main page and closes the Dialog/CKeditor. It's all working magnificently, save for one thing. If someone inserts any JavaScript code, wrapped in 'script' tags, using either the Insert HTML Plugin for CKEditor or by going to 'Source' in CKEditor and placing the code in the source, everything seems okay until they click the 'Update Changes' button. The JavaScript appears to be inserting properly, but when 'Update Changes' is clicked, instead of the Dialog closing and passing the script back into the div where it belongs, what I get instead is an all-white screen with just the output of the JavaScript. For example, a simple 'Hello World' script results in a white screen with the string 'Hello World' in the upper left corner; for more intricate scripts, like an API call to, say Aweber, that generates a newsletter signup form, I get an all-white screen with the resulting form from the Aweber API call perfectly rendered in the middle of the screen. One of the most confusing parts is that, on these pages, if I click 'View Source', I get absolutely nothing. Blank emptiness. Here's all my code that handles the launching of the CKEditor instance inside the jQuery-UI Dialog, and the passing of the edited data back into its associated div on click of the 'Update Changes' button: $(function() { $('.foobar_edit_button') .button() .click(function() { var beingEdited = $(this).nextAll('.foobar_editable').attr('id'); var content = $(this).nextAll('.foobar_editable').html(); $('#foobar_editor').html(content); $('#foobar_editor').dialog( { open:function() { $(this).ckeditor(function() { CKFinder.SetupCKEditor( this, '<?php echo '/foobar/lib/editor/ckfinder/'; ?>' ); }); }, close:function() { $(this).ckeditorGet().destroy(); }, autoOpen: false, width: 840, modal: true, buttons: { 'Update Changes': function() { // TODO: submit changes to server via ajax once its completed: for ( instance in CKEDITOR.instances ) CKEDITOR.instances[instance].updateElement(); var edited_content = $('#foobar_editor').html(); $('#' + beingEdited).html(edited_content); $(this).dialog('close'); } } }); $('#foobar_editor').dialog('open'); }); }); I'm all sorts of confused. If anyone can point me in the right direction, it will be greatly appreciated. Thanks!

We have the following in there now: InnoSetup binaries Third Party Components VCL (including Indy) Our Source (of course) Finalbuilder project files The only thing missing is the binaries for Delphi itself - I am wondering if there is a minimum set of files that can be copied to the repository and run.

  • Emacs persistent folding mode

    - by Chris
    There are plenty of ways to fold code in Emacs and I've settled in on using the outline minor mode... it works great! However, I really want my folding to be persisted when I close and re-open files. It is quite frustrating to have folding set up in a file the way I like it, only to have that lost when I restart Emacs. Has anyone found a way to keep the folding state of a file persistent?
