• Need a regular expression for an Irish phone number

  - by Eoghan O'Brien

  I need to validate an Irish phone number but I don't want to make it too user unfriendly, many people are used to writing there phone number with brackets wrapping their area code followed by 5 to 7 digits for their number, some add spaces between the area code or mobile operator. The format of Irish landline numbers is an area code of between 1 and 4 digits and a number of between 5 to 8 digits. e.g. (021) 9876543 (01)9876543 01 9876543 (0402)39385 I'm looking for a regular expression for Javascript/PHP. Thanks.

• Javascript Grid that can handle sections in a table

  - by user335410

  I am making an ASP.NET MVC application that lets a user design a questionnaire that other users can fill out. Now, questionnaires, rather than just having a list of questions, often have sections or subsections that could have headings and not the other columns that an ordinary row (a question) would have. I want a JS Grid that can handle sections and subsections elegantly. I tried using JQGrid, but there the options I have are limited to a "Grid as Subgrid" structure. The appearance becomes quite complex and unlike a questionnaire. Is there a Javascript Grid or a JQuery plugin that can handle this? I can write my own HTML table as long as the JS app will format the table and will add some user-friendliness to the table.

• How do I mount my Android phone's filesystem on MacOS X? [closed]

  - by misbell

  I'm running a fully rooted Nexus One with Android 2.1. I can see /data/data in DDMS, both the plugin and the tool -- but when I attach my phone, I still can't see the main drive. All I can see is the SD card. Using OSX, when I use Disk Utility, I can see the machine then see the SD Card. Is the problem that none of the tools I am using, except DDMS and ADB shell, know how to read that main Android drive? It's the same format as the qemu img, right? Again -- my goal is to mount the phone's root filesystem on my MacOS X host when connected via USB.

• How do I use dependencies in a makefile without calling a target?

  - by rassie

  I'm using makefiles to convert an internal file format to an XML file which is sent to other colleagues. They would make changes to the XML file and send it back to us (Don't ask, this needs to be this way ;)). I'd like to use my makefile to update the internal files when this XML changes. So I have these rules: %.internal: $(DATAFILES) # Read changes from XML if any # Create internal representation here %.xml: %.internal # Convert to XML here Now the XML could change because of the workflow described above. But since no data files have changed, make would tell me that file.internal is up-to-date. I would like to avoid making %.internal target phony and a circular dependency on %.xml obviously doesn't work. Any other way I could force make to check for changes in the XML file and re-build %.internal?

• Fire only one Custom Validator at a time

  - by Lijo

  I have two Custom Validators attached to a textbox. The textbox is to enter comma separated list of emails. The first validator checks that there is not duplicate email address. The second custom validator checks that all the email addresses are in valid format. I have following code and it works fine. However, when both the failure criteria is met both of them are firing and I get two * at the right side of my textbox. What is the best approach to show only one * at a time? CODE <asp:CustomValidator ID="valEmailRecipients" runat="server" ControlToValidate="txtEmailRecipients" ClientValidationFunction="isUniqueElements" OnServerValidate="IsUniqueEmail_Validate" Text="*" ErrorMessage="There should be no duplicate email address for a report" ValidationGroup="Save"> </asp:CustomValidator> <asp:CustomValidator ID="valEmailFormat" runat="server" ControlToValidate="txtEmailRecipients" ClientValidationFunction="checkEmailFormat" OnServerValidate="IsValidEmailFormat_Validate" Text="*" ErrorMessage="Entries should be valid email addresses separated by comma" ValidationGroup="Save"> </asp:CustomValidator> REFERENCES: Validating with a Custom Function for ASP.NET Server Controls

• Lazy evaluation with ostream C++ operators

  - by SavinG

  I am looking for a portable way to implement lazy evaluation in C++ for logging class. Let's say that I have a simple logging function like void syslog(int priority, const char *format, ...); then in syslog() function we can do: if (priority < current_priority) return; so we never actually call the formatting function (sprintf). On the other hand, if we use logging stream like log << LOG_NOTICE << "test " << 123; all the formating is always executed, which may take a lot of time. Is there any possibility to actually use all the goodies of ostream (like custom << operator for classes, type safety, elegant syntax...) in a way that the formating is executed AFTER the logging level is checked ?

• exportDocument() 'destination folder does not exist' error

  - by dvb

  I'm trying to make a script in photoshop that will modify some layers and than export them as a PNG image. I've copied the following code from another place: function SavePNG(saveFile){ var pngOpts = new ExportOptionsSaveForWeb; pngOpts.format = SaveDocumentType.PNG pngOpts.PNG8 = false; pngOpts.transparency = true; pngOpts.interlaced = true; pngOpts.quality = 100; activeDocument.exportDocument(saveFile,ExportType.SAVEFORWEB,pngOpts); } The function export the active document of photoshop to the file specified by the saveFile parameter. It's working fine with simple paths like 'C:\images\result.png' but when trying with different paths like '~/Desktop/' or paths with some special characters the file isn't exported, and a 'destination folder does not exist' error massage appear. Any idea how can I solve it?

• Method for exporting drawn flash/flex UIComponent to vector based print file

  - by eshowcase

  Hi, I am creating a flex application where I am using the built in graphics package of flex 3 to draw shapes and things to a UIComponent. I want to be able to export this vector image UIComponent to a vector based file, pdf, eps etc. Are there any tools, libraries, or methods for doing so? I looked at AlivePDF - which works very slick, but its output is effectively a snapshot of the UIComponent drawn out as a bitmap to the PDF. I want true vector output, as this image is for print, needs to be able to scale and be color correct. I read somewhere that it may be possible with Adobe Live Cycle, but in looking at the documentation I'm not sure how to use it. Another possibility is to submit the final image parameters to a server-side PHP script that would re-generate the image in SVG format. But as I understand SVG is not ideal for print, and this is lots of extra work. Any thoughts, ideas, methods? Thanks!

• Android how to create notification that resumes activity

  - by Adam Praiswater

  I a have a notification in a receiver that fires off fine, but it restarts the activity (thus clearing the edittexts and resetting the toggle button) How can i set it so that when its tapped on it resumes the activity rather that clearing and resetting everything? My current code doesnt work. Current Code String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date()); Intent intenti= new Intent(context, Locator.class); intenti.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intenti, 0); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context) .setSmallIcon(R.drawable.xxxxxxnotifyicon) .setContentTitle("xxxxxxx Link") .setContentText("Auto Check In Complete at " + currentDateTimeString); mBuilder.setContentIntent(contentIntent); mBuilder.setDefaults(Notification.DEFAULT_SOUND); mBuilder.setAutoCancel(true); NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); mNotificationManager.notify(1, mBuilder.build());

  Every time I write to the text file I will lose the original data, how can I read the file and enter the data in the empty line or the next line which is empty? public void writeToFile() { try { output = new Formatter(myFile); } catch(SecurityException securityException) { System.err.println("Error creating file"); System.exit(1); } catch(FileNotFoundException fileNotFoundException) { System.err.println("Error creating file"); System.exit(1); } Scanner scanner = new Scanner (System.in); String number = ""; String name = ""; System.out.println("Please enter number:"); number = scanner.next(); System.out.println("Please enter name:"); name = scanner.next(); output.format("%s,%s \r\n", number, name); output.close(); }

  - by kriss

  I have a hickup in using printf . I am on ubuntu 10.04. Basically i have a C program asking for some input and then prints it back. It is OK for printing something after inputing. I tried to insert some Hex Address to Stack by following format:- printf "hello world!\x12\x23\x34" | ./input1 But i don't know what is the problem. If i give only string beyond 12 bytes it overwrites BUT If I give hex address(through printf), it doesn't overwrite on return address. Instead it stores some other thing. Could anyone help??? I can't proceed further becoz of this. Thanks in advance

• What are the pro and cons of having localization files vs hard coded variables in source code?

  - by corgrath

  Definitions: Files: Having the localization phrases stored in a physical file that gets read at application start-up and the phrases are stored in the memory to be accessed via util-methods. The phrases are stored in key-value format. One file per language. Variables: The localization texts are stored as hard code variables in the application's source code. The variables are complex data types and depending on the current language, the appropriate phrase is returned. Background: The application is a Java Servlet and the developers use Eclipse as their primary IDE. Some brief pro and cons: Since Eclipse is use, tracking and finding unused localizations are easier when they are saved as variables, compared to having them in a file. However the application's source code becomes bigger and bloated. What are the pro and cons of having localization text in files versus hard coded varibles in source code? What do you do and why?

• Comparing two ISO8601 dates strings in PHP

  - by oompahloompah

  I need to compare (actually rank/sort) dates in a PHP script. The dates are ISO-8601 Date format i.e. YYYY-MM-DD I wrote a comparison function which splits the dates and compares by year/month/day. However, it seems this may be overkill and I could just as easily done a simple string comparison like: if ($date1 < $date2) // do something elseif( $date1 > $date2) //do something else else //do yet another thing Is my assumption about (ISO-8601) Date string comparison correct - i.e. can I get rid of my function (to save a few clock cycles on the server), or is it safer to explicity do the comparison in a custom function?

• Linux application that bundles multiple incoming audio and video streams into one container file?

  - by StackedCrooked

  I've been assigned to implement a video on-demand service for a local university. Different aspects of the lectures (video, audio, screen cast, white board) will be recorded. During a lecture all these data streams arrive at one Linux server. This server should transcode and bundle all these streams into one container (Matroska) file. My options seem to be: Write a GStreamer application do something with FFMPEG do something with VLC ...? Has anyone done something similar in the past? Can you recommend something? Edit For those interested, here are a few of my findings: Matroska is not a good format for streaming (it's possible, but it's not its primary intent) For Flash streaming you can use MPEG4 If you want to combine different videos into one video where each subvideo occupies a rectangular portion of the total screen, then this GStreamer script is useful (I found it on this blog post). Desktop capture works fine with VLC

• Reading from the HTML DOM returns UTF-8 characters

  - by teehoo

  I have a contenteditable div where I'm reading individual characters and sending them off to a server (for more background this is similar to Google Wave where typing a character automatically sends it) I was using a plain old html textfield before and everything worked fine until I "upgraded" to a contenteditable div. My problem is that now the characters are in UTF-8 format, which is causing some weird problems on the server that I would rather not debug. It would be much easier to force everything to be ASCII on the client side. Is there any way to do this? I tried putting in a meta tag stating the html file is charset=ISO-8859-1, but it doesnt seem to work. Reading from the div tag still returns UTF-8 codes. (One example is when I press space I get the pair 0xC2 0xA0 which corresponds to a "non-breaking white space"

• Getting Stored Procedure Information from .Net

  - by Ben

  Hi, I am trying to get some data relevant to a stored procedure (or funtion) back from a database using .Net. The first thing I need to be able to do, is get the stored proc from the database and turn it into string format. The information I need is: The return set of columns, tables used within the SP, Stored Procedures called from the SP. The only way of doing this at the moment that i can think of, is though parsing the text and looking for keyword matches. Is there a better way of doing this? Any ideas? Thanks.

• Sharepoint navigation customization

  - by ifunky

  Hi, I've just started to use Sharepoint 2007, MOSS is installed but for the extranet I'm working on the publishing isn't switched on. What I need to do is customise the global navigation so that it displays all top level & subsite links, custom links and format it nicely with css for the brand. Sounds easy but it isn't for some reason! I've been reading numerous blogs and things about it but can't seem to find anything other than writing lots of code (which I don't mind) to hook into the API or use a customer provider which sounds extreme for something so simple. I was wondering what are the options for this and any good links to articles appreciated so I can finally get this simeple task done. I see the MOSS navigation has extra options for global navigation but I presume as this isn't enabled I couldn't use the same code/control in the master page? Thanks Dan

• running Echo from Java

• How to index and search .doc files

  - by Jared

  I have an application that needs to have .doc files uploaded to it. These documents should then be index and the whole collection of documents should be searchable. This will run on a Windows Server, without Word installed, using IIS and SqlServer, but I'd rather not be tied to SqlServer's full text indexing. I was thinking of using Lucene.Net for the indexing part and was wondering what the best way to get the text out of the .doc files would be. I could probably extract the text by reading in the whole stream and then using a regEx to pull out any regular characters, but that seems hefty and prone to error. I saw an article on using iFilters that sounds promising, but I thought I'd put this out there since it's not something I'm familiar with. P.S. If it matters, these .doc files will have mail-merge fields in them and there's no other current alternative for the .doc format.

• best way to add route under resource in Laravel 4

  I would like know if there is a better way to add additional route aside from the default of resource in Laravel 4. I have this code below which is no problem with regard to the functionality, it's just that it seems to be long: <?php Route::group(array('before' => 'auth'), function() { # API Route::group(array('prefix' => 'api'), function() { Route::resource('projects', 'ProjectsController'); Route::resource('projects.groups', 'GroupsController'); Route::post('/projects/{projects}/groups/{groups}/reorder', 'GroupsController@reorder'); }); }); If in Rails Rails.application.routes.draw do # API namespace :api, defaults: { format: 'json' } do scope module: :v1 do resources :projects do resources :groups do member do post :reorder end end end end end end

• Extracting multiple values from a string with RegEx

  - by Toni Frankola

  I have an input string that's generated as in following example: string.Format("Document {0}, was saved by {1} on {2}. The process was completed {3} milliseconds and data was received.", "Document.docx", "John", "1/1/2011", 45); Generate string looks like this then: Document Document.docx, was saved by John on 1/1/2011. The process was completed 45 milliseconds and data was received. Once such a string is received from a different application, what would be the easiest way to parse with regex and extract values Document.docx, John, 1/1/2011, 45 from it. I am looking for the easiest way to do this as we will have to parse a number of different input strings.

Before to pass to a consumer the XML, I wuold like to check if there are errors and, if so, send back a response with error messages. I read "Active Record Validations and Callbacks" guides on the RoR website, but it seems not work in my case. I extract from the database a resource doing @response = User.find_by_id(1) and I wuold like, if possible, to add error to it.

Maybe something like this: errors.add(:password, "is invalid")
