• Master data validation in service layer

  - by rakesh-nitj

  User enters the data in the forms by choosing values from the master data drop downs in web layer. Data is populated in the dropdowns based on some logic from the master data tables and we know for sure that its a valid master data as far as web layer is concern. Now my question is, should be check the validity of the master data in service layer again because we want to use service layer for mulitple interfaces (Web User Interface, Web Services, Unit Test Cases etc.) or we should validate the master data in respective interfaces only.

• How do I use grep to extract a specific field value from lines

  - by Stormshadow

  I have lines in a file which look like the following ....... DisplayName="john" .......... where .... represents variable number of other fields. Using the following grep command, I am able to extract all the lines which have a valid 'DisplayName' field grep DisplayName="[0-9A-Za-z[:space:]]*" e:\test However, I wish to extract just the name (ie "john") from each line instead of the whole line which is returned by grep. I tried pipelining the output to the cut command but it does not accept string delimiters.

• Still not understanding SVN Repositories in eclipse

  - by jax

  I am about to import my project into svn but don't want to stuff it up. My structure is like this: Repositories: /var/svn/client_name1/ /var/svn/client_name2/ Project directories under /var/svn/client_name1/ project1/ trunk/ branches/ tags/ project2/ trunk/ branches/ tags/ My Apache config looks like this: <Location /svn> DAV svn SVNParentPath /var/svn SVNListParentPath on AuthType Basic AuthName "My Repository" AuthUserFile /etc/svnpass Require valid-user AuthzSVNAccessFile /etc/svnauth </Location> Now I can access my svn repository http://mysite.com/svn/client_name1/ however, there are no projects displayed here, just a Revision 0 message (is that correct)? I can connect to the repository in eclipse using the same url. If I want to place an existing project into the repository what url do I use? http://mysite.com/svn/client_name1/project1 OR http://mysite.com/svn/client_name1/project1/trunk

• Check something before django server starts

  - by Vijay Shankar Kalyanaraman

  I am running my api behind a django server and say I have a one time token that is needed by the django application and used through out its existence until the process quits. To check if I can proceed and serve requests (using the django server) I need to validate this token against a database entry. Now, I can have a script that hits the db, then issues the run server command if the token is valid. But if the db used by the django applications change, I will have to change the script also to point to the same db. Is there a way I can pass this token into the runserver command as an additional parameter (along with hostname:port) and validate this before django serves any requests? How can I access this parameter that is sent into ./manage.py runserver. Thanks.

• Changing all CSS styles with a property via Jquery

  - by Joe

  On a page I include some css eg: <style type='test/css'> .myBox{ color:#000000; border:#FFFFFF; padding:4px; } .myBox2{ color:#000000; border:#FFFFFF; padding:4px; } </style> I want to then change the "color" property set within both myBox and myBox2 in jquery, without knowing the actual name (myBox, myBox2) of the css style. In otherwords, I want to update ALL css styles on the page where color = certain value, and then also update border where = certain value. An example (not valid code) might be: $("all css [color:#000000]").html("#FF0000"); How could this be possible using jquery?

• How to load a resource bundle from a file resource in Java?

  - by user143794

  I have a file called mybundle.txt in c:/temp - c:/temp/mybundle.txt how do I load this file into a java.util.resource bundle? The file is a valid resource bundle. This does not seem to work: java.net.URL resourceURL = null; String path = "c:/temp/mybundle.txt"; java.io.File fl = new java.io.File(path); try { resourceURL = fl.toURI().toURL(); } catch (MalformedURLException e) { } URLClassLoader urlLoader = new URLClassLoader(new java.net.URL[]{resourceURL}); java.util.ResourceBundle bundle = java.util.ResourceBundle.getBundle( path , java.util.Locale.getDefault(), urlLoader ); What is the best way to do this?

• preg_replace - don't include string if $4 is blank

  - by bradenkeith

  I have this expression: $regex_phone = '/^(?:1(?:[. -])?)?(?:\((?=\d{3}\)))?([2-9]\d{2})' .'(?:(?<=\(\d{3})\))? ?(?:(?<=\d{3})[.-])?([2-9]\d{2})' .'[. -]?(\d{4})(?: (?i:ext)\.? ?(\d{1,5}))?$/'; if(!preg_match($regex_phone, $data['phone'])){ $error[] = "Please enter a valid phone number."; }else{ $data['phone'] = preg_replace($regex_phone, '($1) $2-$3 ext.$4', $data['phone']); } That will take a phone number such as: 803-888-8888 ext 2 as well as 803-888-8888 First number formats as: (803) 888-8888 ext.2 -- the desired effect Second number formats as: (803) 888-8888 ext. -- blank extension How can I set it so that if $4 is blank, that ext. won't show? Thanks so much for any help you can offer. I hope this was clear.

• jQuery UI: moving items from one list to another

  - by AnC

  While this should be relatively straightforward, I can't figure out how to move (rather than copy) LI elements between ULs. All I want is to drag any item from list foo to list bar (or vice versa) without duplicating the element. While connectToSortable does almost exactly what I want (though I'd prefer to avoid sortable), it clones the element - and manually removing the original element by reacting to the stop event turns out to be not so easy (e.g. ensuring that a valid drop actually happened). A simple "hello world" example would help me greatly.

• Why can't I pass in a uniqueidentifier/GUID to a stored procedure

  - by chobo2

  Hi I have this SP USE [TestDB] GO /****** Object: StoredProcedure [dbo].[sp_test] Script Date: 06/12/2010 11:47:27 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[sp_test] @id uniqueidentifier AS BEGIN select * from TestTbl where ProductId= @id END I then went to the SP with ms sql 2005 and clicked execute. It comes up with a box where I entered in the GUID. I copied and pasted it straight from my test database. I get this error. Msg 102, Level 15, State 1, Line 5 Incorrect syntax near 'cac671b'. So why can't I sent in GUIDs? even ones that are copied right from the database and must be valid as they where allowed into the db.

• Force an object to be allocated on the heap

  - by Warren Seine

  A C++ class I'm writing uses shared_from_this() to return a valid boost::shared_ptr<>. Besides, I don't want to manage memory for this kind of object. At the moment, I'm not restricting the way the user allocates the object, which causes an error if shared_from_this() is called on a stack-allocated object. I'd like to force the object to be allocated with new and managed by a smart pointer, no matter how the user declares it. I thought it could be done through a proxy or an overloaded new operator, but I can't find a proper way of doing that. Is there a common design pattern for such usage? If it's not possible, how can I test it at compile time?

• How to measure Silverlight or Flash control load time with Google Analytics

  - by ddehghan

  Hi everyone I have a simple silverlight page for for finding available domain names. This problem is equaly valid for a flash control as well. I use Google Analytics for monitoring the traffic. I would like to find out how long it take for users to download and render the Silverlight control. Once the java script on a page is loaded there should be a way to start a timer and then stop the timer once the Silverlight/flash control is loaded. Key points I would like to measure are: Time it takes to download the silverlight/flash control Time it takes to initialize the control Thanks

• MSAccess Change Date Value Before Validation

  - by sisdog

  In a grid I have a date/time field where I would like the user to be able to type in short-hand formats for dates and times. For example, if they type in "435p" and then focus off of the cell they get the message "The value you entered isn't valid for this field.". Instead, I want to trap a pre-validationevent and change it to "4:35pm" for them. What event can I use? I've tried: LostFocus & BeforeUpdate: too late (validation fires before event) Dirty & OnChange: too early (they haven't left the cell yet) Or is there a way to turn off the native validation rule that is checking for date formats?

• Outlook Mobile Service Configuration Issue

  - by cbeckner

  I am working on writing a OMS implementation. I have verified that service is compliant with the service and schema definitions. When trying to set up the account in Outlook 2007 to test the service, it allows me to use an https address, but not an http address. According to the documentation (http://msdn.microsoft.com/en-us/library/bb277363.aspx) "The URL of the OMS Web service can be either http or https, but it is https if not otherwise specified" I have not been able to find any doucmentation that would explain why Outlook will not even let me try to do anything in the wizard if the service url does not start with https. The error that it returns when a http address is entered is: The web service address is incorrect or corrupted. Check the web service address or contact your administrator I have also tried creating a temporary cert on my local machine to test the service, but outlook is rejecting the cert because it is not valid. Is there any way to test the service or run it over http?

• Determining Terminal lines/cols via PHP CLI

  - by eFrane

  I know that it is quite easy to figure out a terminal's size parameters via the stty -a command. When using local CLI PHP scripts, there is no problem at all on grabbing that output via system() or so. But I am trying the same thing via a php script started from an ssh command. Sadly, all that stty ever returns is: stty: standard input: Invalid argument. The calling code is: exec('stty -a | head -n 1', $query); echo $query[0]; So the question is: If I can output to the terminal and read input from it (e.g. can fread() from STDIN and fwrite() to STDOUT in PHP, shouldn't stty also have valid STDIN and STDOUT?

• What characters are widely supported in CSS class names?

  - by last-child

  As detailed here among other places, the only valid characters in a html/css class name is a-z, A-Z, 0-9, hyphen and underscore, and the first character should be a letter. But in practice, what characters are in fact supported by most browsers? More specifically, I wonder what browsers properly understands a slash (/) in a class name, and what browsers support class names starting with a number. I'm primarily interested in getting an answer for html rather than xhtml, in case there is a difference. Thank you.

• jquery draggable accept: classpath

  - by heldopslippers

  Hi guys.. I have problems with the following bit of javascript/jquery code: this.droppable = function(){ $('.imageWindow .body .item').draggable(); $('.groupWindow .body .item').droppable({ accept: $(".imageWindow .body .item"), over: function(event, ui) { alert("this is valid!"); }, drop: function(){ alert('dropped'); } }); } As you maybe know it is not possible to pass the following in the accept option: $(".imageWindow .body .item") But what is possible ? I want to pass a "class path" as an accept option ! It is probably a simple answer but i can't figure it out. Of course i could do: accept: ".item" But because "groupWindow .body .item" is a sortable it would also accept himself! Thanxs if you can help me!

• Replacing whitespace with sed in a CSV (to use w/ postgres copy command)

  - by Wells

  I iterate through a collection of CSV files in bash, running: iconv --from-code=ISO-8859-1 --to-code=UTF-8 ${FILE} | \ sed -e 's/\"//g' | \ sed -e 's/, /,/g' \ > ${FILE}.utf8 Running iconv to fix UTF-8 characters, then the first sed call removes the double quote characters, and the final sed call is supposed to remove leading and trailing whitespace around the commas. HOWEVER, I still have a line like this in the saved file: FALSE,,,, 2.40,, The COPY command in postgres is kind of dumb, so it thinks " 2.40" is not valid syntax for a numeric value. Where am I going wrong w/ my processing of the CSV file? Thanks!

• Circular Reference for Parent Link on Work Item cannot be resolved by Retry

  - by Atters

  I receive the following error; OH-TFS-Connector-0051: Operation failed getCollectionMetaData. Server Error : TF201063: Adding a Parent link to work item 1737 would result in a circular relationship. To create this link, evaluate the existing links, and remove one of the other links in the cycle. I have completely flattened out the Work Items in the source project. When retrying the migration the timestamp is modified on the pending errors however the issues are not resolved. These Work Items now have no parents or children in the source project. So I'm wondering if the retry list is no longer valid but there doesn't appear to be a away to have it update? I can run the whole migration again, however it takes 5-7 hours to just do the work items so it would be great if there is a quick fix.

• Grails: Duplicates & unique constraint validation

  - by rukoche

  OK here is stripped down version of what I have in my app Artist domain: class Artist { String name Date lastMined def artistService static transients = ['artistService'] static hasMany = [events: Event] static constraints = { name(unique: true) lastMined(nullable: true) } def mine() { artistService.mine(this) } } Event domain: class Event { String name String details String country String town String place String url String date static belongsTo = [Artist] static hasMany = [artists: Artist] static constraints = { name(unique: true) url(unique: true) } } ArtistService: class ArtistService { def results = [ [ name:"name", details:"details", country:"country", town:"town", place:"place", url:"url", date:"date" ] ] def mine(Artist artist) { results << results[0] // now we have a duplicate results.each { def event = new Event(it) if (event.validate()) { if (artist.events.find{ it.name == event.name }) { log.info "grrr! valid duplicate name: ${event.name}" } artist.addToEvents(event) } } artist.lastMined = new Date() if (artist.events) { artist.save(flush: true) } } } In theory event.validate() should return false and event will not be added to artist, but it doesn't.. which results in DB exception on artist.save() Although I noticed that if duplicate event is persisted first everything works as intended. Is it bug or feature? :P

• No recent books on MPI: is it dying?

  - by Jono

  I've never used Message Passing Interface (MPI), but I've heard its name thrown about, most recently with Windows HPC Server. I had a quick look on amazon to see if there were any books on it, but they're all dated around 7 or more years ago. Is MPI still a valid technology choice for new applications, or has it been largely superceded by other distributed programming alternatives (e.g. DataSynapse GridServer)? As it's not really an implementation, but rather a standard, what is the likelihood (assuming it's not dead) that learning it will result in better design of distributed programming systems? Is there something else I should be looking at instead?

• iTune redeem codes: limited to a single version?

  - by Big Papoo

  Hi, I'm wondering if V1.0 generated redeem codes will be usable on a V1.1 version of my app? BTW, I know redeem codes are valid only 4 weeks and I also know that apps downloaded with a redeem code can be upgraded for free as with paid ones. My concern here is just: do unused redeem codes become invalid when a new version of my app will be available on the store? Apple's doc is not clear about this point. Did someone experience this yet ? Thx. --GQ.

• sharepoint spweb and spsite disposal

  - by user327045

  I've been using the following code in a .NET 1.1 SharePoint 2003 environment and it works great: try { site = SPControl.GetContextSite(Context); web = site.OpenWeb(); ... } catch (Exception export) { output.Write("Caught Exception: <br/><br/>"); output.Write(export.Message + "<br><br>"); output.Write(export.StackTrace); } finally { if (web != null) web.Dispose(); if (site != null) site.Dispose(); } However, I'm currently porting the code to a .NET 2.0 SharePoint 2007 environment and I get the following error message: "Trying to use an SPWeb object that has been closed or disposed and is no longer valid." If I comment out the Dispose() code, it works fine. But won't this cause memory leaks? What's the best way to fix the problem?

• Test/expand my email regex

  - by Ross

  I'm really not confident with Regex, I know some basic syntax but not enough to keep me happy. I'm trying to build a regular expression to check if an email is valid. So far here's what I've got: [A-Za-z0-9._-]+@[A-Za-z0-9]+.[A-Za-z.]+ It needs to take account of periods in the username/domain and I think it works with multiple TLDs (e.g. co.uk). I'm working with the preg engine in PHP so it needs to work with that. Thanks if you can help!

• Generate MySQL data dump in SQL from PHP

  - by Álvaro G. Vicario

  I'm writing a PHP script to generate SQL dumps from my database for version control purposes. It already dumps the data structure by means of running the appropriate SHOW CREATE .... query. Now I want to dump data itself but I'm unsure about the best method. My requirements are: I need a record per row Rows must be sorted by primary key SQL must be valid and exact no matter the data type (integers, strings, binary data...) Dumps should be identical when data has not changed I can detect and run mysqldump as external command but that adds an extra system requirement and I need to parse the output in order to remove headers and footers with dump information I don't need (such as server version or dump date). I'd love to keep my script as simple as I can so it can be hold in an standalone file. What are my alternatives?
