• LGPL and Dual Licensing Ajax Library

  - by Thomas Hansen

  Hi guys, I'm the previous founder of Gaiaware and Gaia Ajax Widgets and when I used to work there we had this rhetoric (which I have confirmed with some very smart FOSS people is correct) that when using a GPL Ajax library you're basically "distributing" the JavaScript which in turn makes the GPL viral clause kick in and forces people to purchase a proprietary license if they're going to build Closed Source stuff... So now I'm the the LGPL world here with Ra-Ajax which is an LGPL licensed library and I've got no intentions of creating a GPL licensed library since I believe strongly in that the LGPL is the "enabler" of the Open Web to prevail. But something interesting have happened which I think might still give me a "business model" here which is the Linking clause of the LGPL which I think goes something like this (pseudo); "If you link to an LGPL licensed thing you get no restrictions on your own derived works"... But so we started creating something we're calling Ajax Starter-Kits which effectively is a "Project Kickstarter" where you can download a finished project/solution which basically enables you to start out with some pre-done boiler plate code for problems such as Ajax DataGrids, Ajax Calendar Applications, Ajax TreeView Applications etc. And the funny thing is that our users would NOT "link" to these, they would effectively BE our users applications... So to wrap up my question. Would this force users of our LGPL licensed Ajax Starter-Kits to LGPL license their own work? Basically if it does we have a business model (and I get very happy) if not I'd just have to hope people would still like to pay us those $29 for our Starter-Kits to support the project... ;) Help rewarded with extreme gratitude...

• Regex query: how can I search PDFs for a phrase where words in that phrase appear on more than one l

  - by Alison

  I am trying to set up an index page for the weekly magazine I work on. It is to show readers the names of companies mentioned in that weeks' issue, plus the page numbers they are appear on. I want to search all the PDF files for the week, where one PDF = one magazine page (originally made in Adobe InDesign CS3 and Adobe InCopy CS3). I have set up a list of companies I want to search for and, using PowerGREP and using delimited regular expressions, I am able to find most page numbers where a company is mentioned. However, where a company name contains two or more words, the search I am running will not pick up instances where the name appears over more than one line. For example, when looking for "CB Richard Ellis" and "Cushman & Wakefield", I got no result when the text appeared like this: DTZ beat BNP PRE, CB [line break here] Richard Ellis and Cushman & [line break here] Wakefield to secure the contract. [line end here] Could someone advise me on how to write a regular expression that will ignore white space between words and ignore line endings OR one that will look for the words including all types of white space (ie uneven spaces between words; spaces at the end of lines or line endings; and tabs (I am guessing that this info is imbedded somehow in PDF files). Here is a sample of the set of terms I have asked PowerGREP to search for: \bCB Richard Ellis\b \bCB Richard Ellis Hotels\b \bCentaur Services\b \bChapman Herbert\b \bCharities Property Fund\b \bChetwoods Architects\b \bChurch Commissioners\b \bClive Emson\b \bClothworkers’ Company\b \bColliers CRE\b \bCombined English Stores Group\b \bCommercial Estates Group\b \bConnells\b \bCooke & Powell\b \bCordea Savills\b \bCrown Estate\b \bCushman & Wakefield\b \bCWM Retail Property Advisors\b [Note that there is a delimited hard return between each \b at the end of each phrase and beginnong of the next phrase.] By the way, I am a production journalist and not usually involved in finding IT-type solutions and am finding it difficult to get to grips with the technical language on the PowerGREP site. Thanks for assistance Alison

• Reading a POP3 server with only TcpClient and StreamWriter/StreamReader

  - by WebDevHobo

  I'm trying to read mails from my live.com account, via the POP3 protocol. I've found the the server is pop3.live.com and the port if 587. I'm not planning on using a pre-made library, I'm using NetworkStream and StreamReader/StreamWriter for the job. I need to figure this out. So, any of the answers given here: http://stackoverflow.com/questions/44383/reading-email-using-pop3-in-c are not usefull. It's part of a larger program, but I made a small test to see if it works. Eitherway, i'm not getting anything. Here's the code I'm using, which I think should be correct. public Program() { string temp = ""; using(TcpClient tc = new TcpClient(new IPEndPoint(IPAddress.Parse("127.0.0.1"),8000))) { tc.Connect("pop3.live.com",587); using(NetworkStream nws = tc.GetStream()) { using(StreamReader sr = new StreamReader(nws)) { using(StreamWriter sw = new StreamWriter(nws)) { sw.WriteLine("USER " + user); sw.Flush(); sw.WriteLine("PASS " + pass); sw.Flush(); sw.WriteLine("LIST"); sw.Flush(); while(temp != ".") { temp += sr.ReadLine(); } } } } } Console.WriteLine(temp); } So, I'm sending from port 8000 on my machine to port 587, the hotmail pop3 port. And I'm getting nothing, and I'm out of ideas.

• Do I really need an ORM?

  - by alchemical

  We're about to begin development on a mid-size ASP.Net MVC 2 web site. For a typical page, we grab data and throw it up on the web page, i.e. there is not much pre-processing of the data before it is sent to the UI. We're now making the decision whether or not to use an ORM and if yes, which one. We had been looking at EF2 AKA EF4 (ASP.Net Entity Framework in VS 2010) as one possibility. However, I'm thinking a simple solution in this case may be just to use datatables. The reason being that we don't plan to move the data around or process it a lot once we fetch it, so I'm not sure there is that much value in having strongly-typed objects as DTOs. Also, this way we avoid mapping altogether, thereby I think simplifying the code and allowing for faster development. I should mention budget is an issue on this project, as well as speed of execution. We are striving for simplicity anywhere we can, both to keep the budget smaller, the schedule shorter, and performance fast. We haven't fully decided this yet, but are currently leaning towards no ORM. Will we be OK with the no ORM approach or is an ORM worth it?

• Github file size limit changed 6/18/13. Can't push now

  - by slindsey3000

  How does this change as of June 18, 2013 affect my existing repository with a file that exceeds that limit? I last pushed 2 months ago with a large file. I have a large file that I have removed locally but I can not push anything now. I get a "remote error" ... remote: error: File cron_log.log is 126.91 MB; this exceeds GitHub's file size limit of 100 MB I added the file to .gitignore after original push... But it still exists on remote (origin) Removing it locally should get rid of it at origin(Github) right? ... but ... it is not letting me push because there is a file on Github that exceeds the limit... https://github.com/blog/1533-new-file-size-limits These are the commands I issued plus error messages.. git add . git commit -m "delete cron_log.log" git push origin master remote: Error code: 40bef1f6653fd2410fb2ab40242bc879 remote: warning: Error GH413: Large files detected. remote: warning: See http://git.io/iEPt8g for more information. remote: error: File cron_log.log is 141.41 MB; this exceeds GitHub's file size limit of 100 MB remote: error: File cron_log.log is 126.91 MB; this exceeds GitHub's file size limit of 100 MB To https://github.com/slinds(omited_here)/linexxxx(omited_here).git !

• Design/Architecture Advice Needed

  - by Rachel

  Summary: I have different components on homepage and each components shows some promotion to the user. I have Cart as one Component and depending upon content of the cart promotion are show. I have to track user online activities and send that information to Omniture for Report Generation. Now my components are loaded asynchronously basically are loaded when AjaxRequest is fired up and so there is not fix pattern or rather information on when components will appear on the webpages. Now in order to pass information to Omniture I need to call track function on $(document).(ready) and append information for each components(7 parameters are required by Omniture for each component). So in the init:config function of each component am calling Omniture and passing paramters but now no. of Omniture calls is directly proportional to no. of Components on the webpage but this is not acceptable as each call to Omniture is very expensive. Now I am looking for a way where in I can club the information about 7 parameters and than make one Call to Omniture wherein I pass those information. Points to note is that I do not know when the components are loaded and so there is no pre-defined time or no. of components that would be loaded. The thing is am calling track function when document is ready but components are loaded after call to Omniture has been made and so my question is Q: How can I collect the information for all the components and than just make one call to Omniture to send those information ? As mentioned, I do not know when the components are loaded as they are done on the Ajax Request. Hope I am able to explain my challenge and would appreciate if some one can provide from Design/Architect Solutions for the Challenge.

• Django inlineformset validation and delete

  - by Andrew Gee

  Hi, Can someone tell me if a form in an inlineformset should go through validation if the DELETE field is checked. I have a form that uses an inlineformset and when I check the DELETE box it fails because the required fields are blank. If I put data in the fields it will pass validation and then be deleted. Is that how it is supposed to work, I would have thought that if it is marked for delete it would bypass the validation for that form. Regards Andrew Follow up - but I would still appreciate some others opinions/help What I have figured out is that for validation to work the a formset form must either be empty or complete(valid) otherwise it will have errors when it is created and will not be deleted. As I have a couple of hidden fields in my formset forms and they are pre-populated when the page loads via javascript the form fails validation on the other required fields which might still be blank. The way I have gotten around this by adding in a check in the add_fields that tests if the DELETE input is True and if it is it makes all fields on the form not required, which means it passes validation and will then delete. def add_fields(self, form, index) #add other fields that are required.... deleteValue = form.fields['DELETE'].widget.value_from datadict(form.data, form.files, form.add_prefix('DELETE')) if bool(deleteValue) or deleteValue == '': for name, field in form.fields.items(): form.fields[name].required= False This seems to be an odd way to do things but I cannot figure out another way. Is there a simpler way that I am missing? I have also noticed that when I add the new form to my page and check the Delete box, there is no value passed back via the request, however an existing form (one loaded from the database) has a value of on when the Delete box is checked. If the box is not checked then the input is not in the request at all. Thanks Andrew

• How to publish an ASP.NET MVC website

  - by Luke Puplett

  Hello -- I've a site that I'd like to publish to a co-located live server. I'm finding this simple task quite hard. My problems begin with the Web Deploy tool (1.1) giving me a 401 Unauthorized as the adminstrator because port :8172 comes up in the errors and this port is blocked - but the documentation says "The default ListenURL is http://+:80/MsDeployAgentService"! I'm loathe to open another port and I've little patience these days so I thought bu66er it, I'll create a Web Deploy package and import it into IIS on the server over RDP. I notice first that Visual Studio doesn't use a dialog box to gather settings, or use my Publish profiles but seems to use a tab in the project properties, although I think these are ignored when importing the package anyway? I'm now sitting in the import wizard with Application Path and Connection String. I've cleared the conn string as I think this is for some ASP stuff I don't use but when I enter nothing in the Application Path, the wizard barks at me saying that basically I'm a weirdo because most people publish to folders beneath the root site. Now, I want my site to be site.com/Home/About and not site.com/subfolder/Home/About and I think being an MVC routed site that a subfolder will introduce other headaches. Should I go ahead and use the root? Finally, I also want to publish a web service to www.site.com/services/soap which I think IIS can handle. While typing this question, Amazon have delivered my IIS 7 Resource Kit, and I've been scouring the internet but actually I'm getting more confused. Comment here seems to show consensus opinion that Publish isn't for production sites and that real men roll their own. http://stackoverflow.com/questions/260525/asp-net-website-publish-vs-web-deployment-project ...I guess this was pre- Web Deployment Tool era? I'm going to experiment on a spare box for now but any assistance is welcome. Luke

• How do I code Citrix web sites to use a Secure Gateway (CSG)?

  - by RAVolt

  I'm using Citrix's sample code as a base and trying to get it to generate ICA files that direct the client to use their Secure Gateway (CSG) provider. My configuration is that the ICA file's server address is replaced with a CSG ticket and traffic is forced to go to the CSG. The challenge is that both the Citrix App Server (that's providing the ICA session on 1494) and the CSG have to coordinate through a Secure Ticket Authority (STA). That means that my code needs to talk to the STA as it creates the ICA file because STA holds a ticket that the CSG needs embedded into the ICA file. Confusing? Sure! But it's much more secure. The pre-CSG code looks like this: AppLaunchInfo launchInfo = (AppLaunchInfo)userContext.launchApp(appID, new AppLaunchParams(ClientType.ICA_30)); ICAFile icaFile = userContext.convertToICAFile(launchInfo, null, null); I tried to the SSLEnabled information to the ICA generation, but it was not enough. here's that code: launchInfo.setSSLEnabled(true); launchInfo.setSSLAddress(new ServiceAddress("CSG URL", 443)); Now, it looks like I need to register the STA when I configure my farm: ConnectionRoutingPolicy policy = config.getDMZRoutingPolicy(); policy.getRules().clear(); //Set the Secure Ticketing Authorities (STAs). STAGroup STAgr = new STAGroup(); STAgr.addSTAURL(@"http://CitrixAppServerURL/scripts/ctxsta.dll"); //creat Secure Gateway conenction SGConnectionRoute SGRoute = new SGConnectionRoute(@"https://CSGURL"); SGRoute.setUseSessionReliability(false); SGRoute.setGatewayPort(80); SGRoute.setTicketAuthorities(STAgr); // add the SGRoute to the policy policy.setDefault(SGRoute); This is based on code I found on the Citrix Forums; however, it breaks my ability to connect with the Farm and get my application list! Can someone point me to an example of code that works? Or a reference document?

• How to generating comments in hbm2java created POJO?

  - by jschoen

  My current setup using hibernate uses the hibernate.reveng.xml file to generate the various hbm.xml files. Which are then turned into POJOs using hbm2java. We spent some time while designing our schema, to place some pretty decent descriptions on the Tables and there columns. I am able to pull these descriptions into the hbm.xml files when generating them using hbm2jhbmxml. So I get something similar to this: <class name="test.Person" table="PERSONS"> <comment>The comment about the PERSONS table.</comment> <property name="firstName" type="string"> <column name="FIRST_NAME" length="100" not-null="true"> <comment>The first name of this person.</comment> </column> </property> <property name="middleInitial" type="string"> <column name="MIDDLE_INITIAL" length="1"> <comment>The middle initial of this person.</comment> </column> </property> <property name="lastName" type="string"> <column name="LAST_NAME" length="100"> <comment>The last name of this person.</comment> </column> </property> </class> So how do I tell hbm2java to pull and place these comments in the created Java files? I have read over this about editing the freemarker templates to change the way code is generated. I under stand the concept, but it was not to detailed about what else you could do with it beyond there example of pre and post conditions.

• Jquery Form ajaxSubmit not submitting

  - by Gazler

  Hi, I am using the JQuery Form extension to submit a form with AJAX. I have the following code: var options = { beforeSubmit: showRequest, // pre-submit callback success: showResponse, // post-submit callback // other available options: //url: url // override for form's 'action' attribute //type: 'post', // 'get' or 'post', override for form's 'method' attribute //dataType: null // 'xml', 'script', or 'json' (expected server response type) clearForm: true, // clear all form fields after successful submit //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: timeout: 3000 }; $('#composeForm').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).find(':disabled').removeAttr('disabled'); $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); The problem is that the form doesn't appear to be submitting, or atleast the success function is not being called. If I remove the return false, then the submission works, but the page navigates away. Is there a problem in my code that could be causing this? Cheers, Gazler.

• Is it possible to use Indy 10.5.8.0 with Delphi XE?

  - by jachguate

  The case I'm trying to update the INDY to the latest version for my Delphi XE (Update 1), so I downloaded the latest INDY10 file (Indy_4545.zip) from indy.fulgan.com/ZIP. The packages compiles successfully and I can now even see the new version 10.5.8.0 on the about box dialog, but after a IDE restart I got a message saying: No se encuentra el punto de entrada del procedimiento @Idhttp@TIdCustomHTTP@GetRequestHeaders$qqrv en la biblioteca de vínculos dinámicos IndyProtocols150.bpl. My free translation to English: Entry point not found for procedure @Idhttp@TIdCustomHTTP@GetRequestHeaders$qqrv not found on the dynamic link library IndyProtocols150.bpl. After a quick comparision of old and new IdHTTP.pas I found a lot of changes on the TIdCustomHttp class, including the rename of some methods GetResponseHeaders to GetResponse GetRequestHeaders to GetRequest SetRequestHeaders to SetRequest Along with changed public/published method firms in this and other and classes interfaces. After the update, I got a lot of packages failing to load, including dclcxPivotGridOLAPD15.bpl, which in turns depends on dclDataSnapServer150.bpl which encounters the missing method on the bpl. AFAIK I can't recompile the dclDataSnapServer150.bpl (and maybe other failing packages, I just stopped here). DataSnap and DevExpress support on the IDE is a must for my day to day so The questions Is there a safe pre-established path to update to the newest INDY for Delphi XE? If not, am I on the safe side by just parching the source code by creating the old public methods and call the new ones on the implementation part? am I missing something else or am I really stuck with INDY 10.5.7 until the next Delphi minor/major release?

• Internet Explorer 8 timeout too quick on page POSTs

  - by cdm9002

  We have an asp.net site running, which has been working fine for some time, but recently I have been experiencing some issues with IE8. On posting some pages - mainly on our development server, although on staging too - we get an occasional "Internet Explore cannot display the webpage" error along with the button asking to diagnose connection problems. IE only seems to wait 10 seconds before timing out. I know that the page itself may take longer to load the first time (on dev and staging). So press F5 and everything then works fine. Is there anything that should be done in the aspx page to tell IE to wait a bit longer? I thought I had read that the default timeout supposed to be 90 seconds or something for browsers. A bit more info: It mostly happens on a POSTing a signup page, but that is just because I test that page and it starts the IIS App, makes the first connection to SQL and pre-caches some information. That first time the page can take 10-15 seconds to come back. IE8 times out after 10 seconds as it has had nothing back. This happens on a dev W7x64 machine with 8GB RAM, as well as on a staging server WIN2008. Having googled around a bit, some people are seeing the same problem, but no conclusive pointers to the problem or a solution. It isn't a connection problem; everything works fine in Firefox, Chrome and even IE7; I have tried with add-ons disabled and resetting IE settings, still happens. Ideas welcome.

• Problems with Continuous Integration (CI) in TFS during Build Automation?

  - by Steve Johnson

  Hi all, I am using TFS 2008 and Visual Studio and my boss has instructed me to implement Build Automation for Development and Release builds for a web Project. I am a total newbie in Build Automation. There are multiple developers working on the project on different machines using Visual Studio 2008 team System. Source is already being maintained on TFS 2008. SQL Server in Use is SQL Server 2000 and hosted IIS is IIS 7.5 on Windows Server 2008 x64. I have searched over the net and found Continuous Integration and Nightly Builds as two important Build Automation techniques. I was just wondering of any disadvantages associated with both the methodologies (CI and Nightly Builds). If someone could guide me to a working tutorial that explains both techniques the it would be quite helpful. Please also tell the requirements of IIS, SQL Server and any other that might be pre-requisite to implement build automation. Also i would like to know whether there are other techniques that are better then CI? Replies and discussion much appreciated. Thanks

As far as I can tell there is no way to get the Runtime.exec() method to resolve/evaluate any environment variables referenced in the command String (or array of Strings). I know that if push comes to shove I can write some code to pre-process the command String(s) and resolve enviroment variables by hand (using getEnv() etc). However I'm wondering if there is a smarter way to do this since I'm sure I'm not the only person wanting to do this and I'm sure there are pitfalls in "knocking up" my own implementation. Your guidance and suggestions are most welcome. edit: I would like to refer to environment variables in the command string using some consistent notation such as $VAR and/or %VAR%. Not fussed which. edit: To be clear I'd like to be able to execute a command such as: perl $SCRIPT_ROOT/somePerlScript.pl args on Windows and Unix hosts using Runtime.exec(). I specify the command in config file that describes a list of jobs to run and it has to be able to work cross platform, hence my thought that an environment variable would be useful to factor out the filesystem differences (/home/username/scripts vs C:\foo\scripts). Hope that helps clarify it. Thanks. Tom

• Wrapping mailmessage headers in .net for Sendgrid

  - by mickyjtwin

  Am using SendGrid for some email notifications, specifically utilising their SMTP API's. While they have PHP examples, c# is not so helpful. Essentially, a json string is built that contains the to email addresses, and other custom filters etc, which is then added to a MailMessage header to send. // json string example {"to":["[email protected]", [email protected]", "", ""],"sub":{"<name>":["Name1", Name2"]}} MailMessage m = new MailMessage("[email protected]", "[email protected]"); m.Headers.Add("X-SMTPAPI", jsonString); The problem I am having is that for some MTA's, headers can only be 1000 characters long, and also quoted-principle encoding required only 76 character per line. In their php example, they are splitting the string and adding a linebreak (\n) every 72 characters. While I am doing this in .NET, I am receiving a invalid character exception. After some digging, it seems that pre-.NET4.0 Beta2 MailMessage will not process CLLR characters. Sengrid support is not proving helpful, and looking at ways to make this work?

• Dynamic programming in VB

  - by Rahul Jain

  Hello Everybody, We develop applications for SAP using their SDK. SAP provides a SDK for changing and handling events occuring in the user interface. For example, with this SDK we can catch a click on a button and do something on the click. This programming can be done either VB or C#. This can also be used to create new fields on the pre-existing form. We have developed a specific application which allows users to store the definition required for new field in a database table and the fields are created at the run time. So far, this is good. What we require now is that the user should be able to store the validation code for the field in the database and the same should be executed on the run time. Following is an example of such an event: Private Sub SBO_Application_ItemEvent(ByVal FormUID As String, ByRef pVal As SAPbouiCOM.ItemEvent, ByRef BubbleEvent As Boolean) Handles SBO_Application.ItemEvent Dim oForm As SAPbouiCOM.Form If pVal.FormTypeEx = "ACC_QPLAN" Then If pVal.EventType = SAPbouiCOM.BoEventTypes.et_LOST_FOCUS And pVal.BeforeAction = False Then oProdRec.ItemPressEvent(pVal) End If End If End Sub Public Sub ItemPressEvent(ByRef pVal As SAPbouiCOM.ItemEvent) Dim oForm As SAPbouiCOM.Form oForm = oSuyash.SBO_Application.Forms.GetForm(pVal.FormTypeEx, pVal.FormTypeCount) If pVal.EventType = SAPbouiCOM.BoEventTypes.et_LOST_FOCUS And pVal.BeforeAction = False Then If pVal.ItemUID = "AC_TXT5" Then Dim CardCode, ItemCode As String ItemCode = oForm.Items.Item("AC_TXT2").Specific.Value CardCode = oForm.Items.Item("AC_TXT0").Specific.Value UpdateQty(oForm, CardCode, ItemCode) End If End If End Sub So, what we need in this case is to store the code given in the ItemPressEvent in a database, and execute this in runtime. I know this is not straight forward thing. But I presume there must be some ways of getting these kind of things done. The SDK is made up of COM components. Thanks & Regards, Rahul Jain

• Firebird sequence-backed ID shorthand

  - by pilcrow

  What do others do to simplify the creation of simple, serial surrogate keys populated by a SEQUENCE (a.k.a. GENERATOR) in Firebird = 2.1? I finc the process comparatively arduous: For example, in PostgreSQL, I simply type: pg> CREATE TABLE tbl ( > id SERIAL NOT NULL PRIMARY KEY, > ... In MySQL, I simply type: my> CREATE TABLE tbl ( > id INT NOT NULL PRIMARY KEY AUTO_INCREMENT, > ... But in Firebird I type: fb> CREATE TABLE tbl ( > id BIGINT NOT NULL PRIMARY KEY, > ... fb> CREATE SEQUENCE tbl_id_seq; fb> SET TERM !!; > CREATE TRIGGER tbl_id_trg FOR tbl > ACTIVE BEFORE INSERT POSITION 0 > AS > BEGIN > IF ((new.id IS NULL) OR (new.id <= 0)) THEN > BEGIN > new.id = GEN_ID(tbl_id_seq, 1); > END > END !! > SET TERM ; !! ... and I get pretty bored by the time I reach trigger definition. However, I routinely make SEQUENCE-backed ID fields for temporary, developement and throw-away tables. What do others do to simplify this? Work with an IDE? Run a pre-processing, in-house perl script over the DDL file? Etc.

• POSIX AIO Library and Callback Handlers

  - by Charles Salvia

  According to the documentation on aio_read/write, there are basically 2 ways that the AIO library can inform your application that an async file I/O operation has completed. Either 1) you can use a signal, 2) you can use a callback function I think that callback functions are vastly preferable to signals, and would probably be much easier to integrate into higher-level multi-threaded libraries. Unfortunately, the documentation for this functionality is a mess to say the least. Some sources, such as the man page for the sigevent struct, indicate that you need to set the sigev_notify data member in the sigevent struct to SIGEV_CALLBACK and then provide a function handler. Presumably, the handler is invoked in the same thread. Other documentation indicates you need to set sigev_notify to SIGEV_THREAD, which will invoke the callback handler in a newly created thread. In any case, on my Linux system (Ubuntu with a 2.6.28 kernel) SIGEV_CALLBACK doesn't seem to be defined anywhere, but SIGEV_THREAD works as advertised. Unfortunately, creating a new thread to invoke the callback handler seems really inefficient, especially if you need to invoke many handlers. It would be better to use an existing pool of threads, similar to the way most network I/O event demultiplexers work. Some versions of UNIX, such as QNX, include a SIGEV_SIGNAL_THREAD flag, which allows you to invoke handlers using a specified existing thread, but this doesn't seem to be available on Linux, nor does it seem to even be a part of the POSIX standard. So, is it possible to use the POSIX AIO library in a way that invokes user handlers in a pre-allocated background thread/threadpool, rather than creating/destroying a new thread everytime a handler is invoked?

• Highlighting a Table Correctly Despite rowspan and colspan attributes - WITHOUT jQuery

  - by ScottSEA

  Thanks to some !#$#@ in another department who wrote some crap code, I am unable to use the jQuery library - despite my fervent desire to do so. Their software has already been released into the world, and I have to be compatible. ============================================ I am trying to highlight a table. Desired behavior: Clicking on a cell in the body highlights the row. Clicking on a cell in the head highlights the column. If a column and row are both highlighted, the intersection is highlighted a different color (super-highlight). Clicking on a previously super-highlighted cell turns off the highlights. This behavior is simple enough to do with a basic table, but when rowspans and colspans start rearing their ugly heads, things start to get a little wonky... highlighting cell[5], for instance, no longer works reliably. My thought, in order to speed execution time of the highlighting itself (by changing a class name), is to pre-calculate the 'offsets' of all cells - with a 'colStart' and 'colEnd', 'rowStart' and 'rowEnd' when the page loads and store that in an array somehow. The question: How would YOU implement this functionality? I am fairly rusty at my JavaScript, awfully rudimentary in my programming skills and would benefit greatly from some guidance. Thanks, Scott.

• Spaces and backslashes in Visual Studio build events

  - by gencha

  I have an application that is supposed to aid my project in terms of pre- and post-build event handling. I'm using ndesk.options for command line argument parsing. Which gave me weird results when my project path contains spaces. I thought this was the fault of ndesk.options but I guess my own application is to blame. I call my application as a post-built event like so: build.exe --in="$(ProjectDir)" --out="c:\out\" A simple foreach over args[] displays the following: --in=c:\my project" --out=c:\out" What happened is that the last " in each parameter was treated as if it was escaped. Thus the trailing backslash was removed. And the whole thing is treated as a single argument. Now I thought I was being smart by simply escaping the first " as well, like so: build.exe --in=\"$(ProjectDir)" --out=\"c:\out\" In that case the resulting args[] look like this: --path="c:\my project" --out="c:\out" The trailing backslash in the parameters is still swallowed and the first parameter is now split up. Passing this args[] to ndesk.options will then yield wrong results. How should the right command line look so that the correct elements end up in the correct args[] slots? Alternatively, how is one supposed to parse command line arguments like these with or without ndesk.options? Any suggestion is welcome. Thanks in advance

• Replacing XML reserved characters in SQL Server 2005

  - by Barn

  I'm working on a system that takes relational data from a sql server DB and uses SSIS to produce an XML extract using sql server 2005's 'FOR XML PATH' command and a schema. The problem lies with replacing the XML reserved characters. 'FOR XML PATH' is only replacing <, , and &, not ' and ", so I need a way of replacing these myself. I've tried pre-processing the fields in the database to replace XML reserved characters with their entitised equivalents (e.g. & becomes &amp;), but once these fields are used to construct XML using FOR XML the leading & is replaced with &amp;, so I end up with &amp;amp; where I should have &amp;. What I've tried so far is altering the element's contents after the XML has been constructed using XQuery inside SQL server like so: DECLARE @data VARCHAR(MAX) SET @data = CONVERT(VARCHAR(MAX), [my xml column].query(' data(/root/node_i_want)') SELECT @data = [function to replace quotes etc](@data) SET [my xml column].modify('replace value of (/root/node_i_want)[1] with sql:variable("@data")') but I get the same problem. Essentially, is there something wrong I'm doing with the above, or a way to tell FOR XML to entitise other characters, or something like that? Basically anything short of having to write a program to change the XML after it has been assembled in large batches and saved to files!
