• algorithm for image comparison

  - by Rajnikant

  Please consider following use case, I have one bigger image, lets called is master image. Now from some where else, I am getting one small image. I want to check whether this small image is subset of master image or not. important points are, smaller image might have different file format, smaller image might captured from comparatively different view. smaller image may have different light intensity. At this stage of algorithm/computation advancement, which level of accuracy I could expect? Any algorithm/open source implementation that would have such implementation? Thanks, Rajnikant

• HTML text-area editor for code that traps TAB key

  - by Cristi Cotovan

  Hello, I have looked for months now, for JavaScript-based HTML editor I can embed onto my web pages to replace a TEXTAREA, but to enable me to edit CODE in a friendly, closer to a real editor, way. All editors I've tried (RadEditor from Telerik, FCKEditor, TinyMCE, etc etc), do not trap the TAB key, very useful when editing HTML code onto a page, to help format the code properly. I'm not talking about syntax highlighting, as that would be an awesome plus. But I am mainly wondering if there is such an editor. I'd appreciate being pointed in the right direction.

• Automated fake mailbox

  - by Bernabé Panarello

  Hello, i'm about to start the development of a new automated-email application. The idea is that customers (or other external users) send emails to a mailbox and then an automated process will read them, extract their information and insert it into some database. It's a requirement that the emails have an standard format in order to be parsed (standard subject, etc.). The obvious thing to do would be to set up a process that periodically pools an ordinary mailbox, through pop-3 for example, processing the messages it finds. However, it would be for me much nicer to be able to process the emails as they arrive. I was wondering then, is there any way to set up a process that acts as a fake email-box? do you know about any open-source implementation of something like that I can extend? I would prefer something already written in c#. Thanks in advance for your help, bernabé

• iPhone - how to store documents consisting of multiple images?

  - by Joe Strout

  My iPhone (actually, iPad) app creates documents that consist of several images, plus a bit of metadata. What's the best practice for storing these sorts of documents on disk? I see two main options: Create a folder for each document, and store my images as separate PNG files within the folder (plus another little file for the metadata). Create a single file which contains all images and metadata. But I'm not sure how to easily do option 2. I think I can convert my images in PNG format to/from NSData, but then what? I'm still a newbie at Cocoa, but I believe I saw something about stuffing mixed data into some NSSomethingOrOther and having this write itself out to disk, and read itself back in later. Does this ring a bell with anyone? And, will it work with large binary blobs of data like my images? Or would you recommend I simply go with option 1?

• How to recursively serialize an object using reflection ?

  - by Tony

  I want to navigate to the N-th level of an object, and serialize it's properties in String format. For Example: class Animal { public String name; public int weight; public Animal friend; public Set<Animal> children = new HashSet<Animal>() ; } should be serialized like this: {name:"Monkey", weight:200, friend:{name:"Monkey Friend",weight:300 ,children:{...if has children}}, children:{name:"MonkeyChild1",weight:100,children:{... recursively nested}} } And you may probably notice that it is similar to serializing an object to json. I know there're many libs can do this, can you give me some instructive ideas on how to write this?

• Problem retrieving Hostaddress from Win32_TCPIPPrinterPort

  - by Anthony

  I'm running into an odd issue retrieving printer port addresses. When I get all the entries in Win32_TCPIPPrinterPort, the HostAddress field (which should have the IP address) is usually blank/null, only the port name has a value. To make it a bit stranger, if a particular port is not in use by any printer, THEN the HostAddress will have the the proper value. The C# code is simple, and results in something like this; IP_192.168.1.100, printerportxyz, richTextBox1.Clear(); ManagementObjectSearcher portSearcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_TCPIPPrinterPort"); foreach (ManagementObject port in portSearcher.Get()) { richTextBox1.AppendText( String.Format("Name: {0} HostAddress: {1}", port["Name"], port["HostAddress"]) ); } I also tried the same thing in WSH/VBS, and saw the same behavior.

• How do i convert hdb file? ... believed to be from act! source

  - by Wardy

  Any ideas ? I think the original source was a goldmine database, looking around it appears that the file was likely built using an application called ACT which I gather is a huge product I don't really want to be deploying for a one off file total size less than 5 meg. So ... Anyone know of a simple tool that I can run this file through to convert it to a standard CSV or something? It does appear to be (when looking at it in notepad and excel) in some sort of csv type format but it's like the data is encrypted somehow.

• How to set timezone in jquery countdown timer

  - by Kalpana

  I want to set GMT+5:30 as my timezone in jquery countdown. Start Time for countdown is 'Thu May 20 16:00:00 IST 2010' End Time is 'Thu May 20 17:00:00 IST 2010' as value. +330 is my timezone given in minutes. But my countdown starts from 00:35:00. I would have expected the countdown to start from 01:00:00 Not sure why this is discrepancy is there. <script type="text/javascript"> $(function () { var endTime = '#{myBean.getCountDownDate()}'; $('#defaultCountdown').countdown({ until: endTime, format: 'HMS', timezone: +330, compact: true, description: '#{myBean.getCountDownDate()}'}); }); </script>

• Word 2007 Question

  - by Lijo

  Hi Team, While preparing a Word 2007 document, I made a mistake. (Not to say I don't have any other copy of the document) While formatting (as a try) I applied the style "Apply Style to Body to match selection". This caused the document to go totally in a wronfg format - having numbers even in tables. Have you ever faced this? Could you please tell how to correct it? Hope you would be kind enough to answer this even though it is not striclty technical. Thanks Lijo

• Searching for Records

  - by 47

  I've come up with a simple search view to search for records in my app. The user just enters all parameters in the search box then all this is matched against the database, then results are returned. One of these fields is the phone number....now in the database it's stored in the format XXX-XXX-XXX. A search, for example, for "765-4321" pull up only "416-765-4321...however I want it to return both "416-765-4321" and "4167654321" My view is as below: def search(request, page_by=None): query = request.GET.get('q', '') if query: term_list = query.split(' ') q = Q(first_name__icontains=term_list[0]) | Q(last_name__icontains=term_list[0]) | Q(email_address__icontains=term_list[0]) | Q(phone_number__icontains=term_list[0]) for term in term_list[1:]: q.add((Q(first_name__icontains=term) | Q(last_name__icontains=term) | Q(email_address__icontains=term) | Q(phone_number__icontains=term)), q.connector) results = Customer.objects.filter(q).distinct() all = results.count() else: results = [] if 'page_by' in request.GET: page_by = int(request.REQUEST['page_by']) else: page_by = 50 return render_to_response('customers/customers-all.html', locals(), context_instance=RequestContext(request))

• PHP: How to use mysql fulltext search and handle fulltext search result

  - by garcon1986

  Hello, I have tried to use mysql fulltext search in my intranet. I wanted to use it to search in multiple tables, and get the independant results depending on tables in the result page. This is what i did for searching. $query = " SELECT * FROM testtable t1, testtable2 t2, testtable3 t3 WHERE match(t1.firstName, t1.lastName, t1.details) against(' ".$value."') or match(t2.others, t2.information, t2.details) against(' ".$value."') or match(t3.other, t2.info, t2.details) against(' ".$value."') "; $result = mysql_query($query)or die('query error'.mysql_error()); while($row = mysql_fetch_assoc($result)){ echo $row['firstName']; echo $row['lastName']; echo $row['details'].'<br />'; } Do you have any ideas about optimizing the query and format the output of search results?

• Experiences with UI Automation and WPF

  - by soren.enemaerke

  We are developing a rather large WPF based application and would like to include some automated UI testing in our test suite (which already contains a number of unit tests). The UI Automation Framework from Microsoft partly sounds like a perfect fit for programatically launching and interacting with the application in a test setup. However, I've struggled to find solid references for samples and experiences with the technology, the articles and small samples available on MSDN is not enough to convince me that it is a solid choice. So, does anybody have real world experiences using the UI Automation Framework in their test suite? What are the caveats and the gotchas? Any best practices when written tests scripts, can you "record and replay" to a scriptable format, how much should you facilitate the testing from the application, how did you incorporate it in the automatic build? Should we be looking in another direction than the UI Automation Framework? Feel free to post you experiences here or link to some good references I might have missed

• best way to parse plain text file with a nested information structure

  - by Beffa

  The text file has hundreds of these entries (format is MT940 bank statement) {1:F01AHHBCH110XXX0000000000}{2:I940X N2}{3:{108:XBS/091502}}{4: :20:XBS/091202/0001 :25:5887/507004-50 :28C:140/1 :60F:C0914CHF7789, :61:0912021202D36,80NTRFNONREF//0887-1202-29-941 04392579-0 LUTHY + xxx, ZUR :86:6034?60LUTHY + xxxx, ZUR vom 01.12.09 um 16:28 Karten-Nr. 2232 2579-0 :62F:C091202CHF52,2 :64:C091302CHF52,2 -} This should go into an Array of Hashes like [{"1"=>"F01AHHBCH110XXX0000000000"}, "2"=>"I940X N2", 3 => {108=>"XBS/091502"} etc. } ] I tried it with tree top, but it seemed not to be the right way, because it's more for something you want to do calculations on, and I just want the information. grammar Mt940 rule document part1:string spaces [:|/] spaces part2:document { def eval(env={}) return part1.eval, part2.eval end } / string / '{' spaces document spaces '}' spaces { def eval(env={}) return [document.eval] end } end end I also tried with a regular expression matches = str.scan(/\A[{]?([0-9]+)[:]?([^}]*)[}]?\Z/i) but it's difficult with recursion ... How can I solve this problem?

• What is the regular expression for valdating a 'price' in a jtextfield

  - by wniroshan

  I want to validate a jtextfield as user inputs a price of some item. I have a perfectly working code which beeps and discard if user inputs some character that doesnt match the regular expression.(for regular expression "[0-9]+" it accepts any number of digits and beeps if a letter is given as input) But the problem is I want to validate an input like "12500.00". Format should be any number of digits before decimal point and two digits after the decimal point. eg: ddd.dd I tried the following regular expression. But the i doesnt allow user to input "." character. It allows user to input any number of digits but when "." key is pressed input is not accepted. here is the regular expression I used. "[0-9]+ | [0-9]+. | [0-9]+.[0-9]{1} | [0-9]+{2}" important: user input is validated character by character as the user inputs them to the jtextfield.

• Using CGContext to display a sprite sheet iPhone

  - by Mike

  Hello, So I have a spritesheet in png format, and have already worked out the coordinates for what I want to display. I'm trying to create a method that will return a UIImage when passed the location information on the spritesheet. I'm just not sure how to use the CGContext stuff along with the the coordinates to return an UIImage. I was looking to CGContextClipToRect because I think that is the way to do it, but I just can't seem to get it to work. Something like this CGSize size = CGSizeMake(xSize, ySize); UIGraphicsBeginImageContext(size); //CGContextClipToRect(spriteSheet.size, imageRect); [spriteSheet drawAtPoint:CGPointMake(xPos, yPos)]; UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return scaledImage; returns only what is in the size Context. I need to be able to "move" this size window around the spritesheet if that makes sense. Any help would be appreciated. Thanks, Mike

• PHP-GD: Dealing with Unicode characters

  - by sehugg

  I am developing a web service that renders characters using the PHP GD extension, using a user-selected TTF font. This works fine in ASCII-land, but there are a few problems: The string to be rendered comes in as UTF-8. I would like to limit the list of user-selectable fonts to be only those which can render the string properly, as some fonts only have glyphs for ASCII characters, ISO 8601, etc. In the case where some decorative characters are included, it would be fine to render the majority of characters in the selected font and render the decorative characters in Arial (or whatever font contains the extended glyphs). It does not seem like PHP-GD has support for querying the font metadata sufficiently to figure out if a character can be rendered in a given font. What is a good way to get font metrics into PHP? Is there a command-line utility that can dump in XML or other parsable format?

• Dealing with unwanted port numbers on localhost when debugging in Visual Studio

  - by Dan Bailiff

  So when I'm trying to debug a project in Visual Studio, I'll often have 1 or more services that I need to call. These services are separate projects and I'll launch them in separate instances of VS. ASP dev server kindly launches them with temporary port numbers attached. This would be fine except for my programs are looking for an IP without a port attached. (Typically it's as simple as "localhost"!) I've coped by using web config settings and changing the xml to use the port number while debugging. This still doesn't always work and occasionally I'll still have to fudge it and insert port numbers as strings in code! UGH! Then I have to remember to undo all the port herding code before deployment... I want to stop doing this: string _strBaseURL = String.Format("http://{0}:2277", ConfigurationManager.AppSettings["myservice_ip"].ToString()); What is the best practice here? Am I doomed to port herding while debugging VS apps?

• Textarea to paragraphs

  - by zaf

  When I have to render textarea content to the front end I usually pass it thru a function that converts newlines to <br/> tags and double newlines signal paragraph tags so blocks of text get surrounded by <p> and </p> tags. To save time I usually use a ready made PHP function from the wordpress codebase. You can get the link from the man himself: http://ma.tt/scripts/autop/ If you check it out you'll see it does some heavy lifting with about 20 regular expressions. I know I could use a wysiwyg editor (like TinyMCE or CKEditor) that can format the data on the client and then send it to the server (most of them add <p>..</p> tags by default) but I want to know the experience of others in handling raw textarea input and then displaying it on the front end.

• Python File Meta Tag reading

  - by Jeff

  Anyone know of a Python module that can pull Tag data from multiple media formats? Trying to build an app that allows for manipulation of ASF (Windows Media Player files, ie WMA, WMV, etc), ID3, including both ID3v1 and ID3v2 (MPEG files, ie MP3), MPEG Audio Bit Stream (ie ABS, MP1, MP2, MP3), MPEG Program Stream (MPEG movies, and DVD and HD DVD video discs, ie MPG, MPEG, VOB, EVO), and ISO Base Media File Format (eg QuickTime, MPEG-4 and iTunes AAC files, ie QT, MOV, MP4, M4A, M4B, M4P, M4V, etc). Don't need ALL of that but just most standard consumer formats like mov and mpeg. I can't seem to find a good module to support that or a library. Any recommendations?
