• System_Daemon and shell_exec

  - by Jesse

  Hey Everyone, I've set up a daemon (daemon.php) using PEAR's System_Daemon which waits for something to appear in the database. Once something is there, the daemon gets enough information and sends it out to another script (execute.php) using the shell_exec command this way I'm not worried about waiting for a response and holding up the daemon. Both of the scripts work fine alone and I'm even able to call shell_exec before calling System_Daemon::start(); . However, if I trying calling it AFTER System_Daemon::start();, then I get an Access Denied only when outputting to a file. I'm still new to Daemons in general, so any ideas or thoughts would be great! Thanks Guys!

• How can I include .pdf files when I publish but not in a search and replace in visual studio?

  - by Mike

  More specifically my problem is if I include a pdf in my project and set its build action to content so it gets copied to the server when I publish, is there a way to exclude it from visual studios search and replace feature. Would a post build action be a solution to this? I just don't want anybody to do a global search and replace in my project and mess up the pdfs... I know I just said a mouth full so let me know if you need clarification. Thanks!!!

• Add HTML Id's to tags in .aspx file

  - by slandau

  So I'm writing an app that lets the user select a folder, it gets all the .aspx files in that folder, and lets the users check off which ones they want to add HTML ID's to. Then they click start, and this runs private void btnStart_Click(object sender, EventArgs e) { for (int i = 0; i < listFiles.CheckedItems.Count; i++) { } } It loops through all the selected file names. How do I open each of these .aspx files in the background, and go through them and add the id="thisItemId" attribute to each tag that's like a , , , , , etc....

• Jquery sortable

  - by Nishima

  function dropMembers() { $("ul.present").sortable({ connectWith: 'ul', containment: 'window' //containment: 'ADD_MEMBER_DIALOG' // sort: function(event, ui) { // var present_result=$("ul.present").sortable('toArray'); // // alert(ui.sortable); // } }); $("ul.usrlist").sortable({ connectWith: 'ul', dropOnEmpty: true, containment: 'window' // sort: function(event, ui) { // var usr_result=$("ul.usr").sortable('toArray'); // //alert(ui.sortable); // } }); $("#USER_PRESENT_LIST, #MAIN_USER_LIST").disableSelection(); } Hi All, The function given above does sorting between two list but if a move an element from one list over the other and drop it outside the window then what happens is the element that i dragged gets appeneded in the other list at the place from where i moved it. Can anyone tell me how can i stop it from appeneding in the other list and if i try to do the same thing as mentioned above then it should get back to the same list from where it was dragged. Thanks

• How to debug Fluent nHibernate

  - by Matt Thrower

  Hi, I'm having some trouble with Fluent nHibernate. I added a column to a table and I thought I'd correctly changed the mappings and the connected data objects to correctly reflect this. However when I tried to run my application again I kept getting this error: System.Data.SqlClient.SqlException: Invalid column name 'Workflow_id'. I really couldn't see what the problem was with the changes I'd made so I reverted back to the original versions of the mapping and data object files from source control and removed the offending column from the database. But I'm still getting the same error. I'd like some advice on how to debug this. The SQL that gets reported on the error is semi-nonsensical: SELECT regions0_.Page_id as Page5_1_, regions0_.Id as Id1_, regions0_.Id as Id27_0_, regions0_.RegionId as RegionId27_0_, regions0_.RegionTemplate_id as RegionTe3_27_0_, regions0_.Workflow_id as Workflow4_27_0_ FROM [Region] regions0_ WHERE regions0_.Page_id=? And it won't execute as valid SQL anyway. Any ideas as to where to go from here?

• How do I create multiple submit buttons for the same form in Rails?

  - by Angela

  I need to have multiple submit buttons. I have a form which creates an instance of Contact_Call. One button creates it as normal. The other button creates it but needs to have a different :attribute value from the default, and it also needs to set the attribute on a different, but related model used in the controller. How do I do that? I can't change the route, so is there a way to send a different variable that gets picked up by [:params]? And if I do then, what do I do in the controller, set up a case statement?

• Dynamically create and cast objects at runtime

  - by vaibhav bindroo

  Let's say we have 2 classes A and B public class A{ private int member1; A() { member1 = 10; } public getMember(){ return member1; } } Class B is also on the same lines except that its member variable is named member2 and gets intitialized to say 20 inside the constructor. My Requirement : At runtime , I get a string which contains a className ( could be A or B). I want to dynamically create an object of this class along with invoking the constructor. How can I achieve this . I don't want to use interfaces for common functionality of above classes Morever, later on I set the properties of this raw object using Propery Builder Bean Util class based on a list of columns . Class clazz = Class.forName("className"); Obj obj = clazz.newInstance(); How I can dynamically convert that obj to className object.

• Using unless in rails uniqueness validation

  - by dunxd

  I am just starting out in Rails, and trying to develop a simple application. I need to validate three values submitted to the application - each must meet the same validation criteria. The validation is pretty simple: Value is valid if unqiue, null or equal to "p" or "d". The following gets me halfway there: validates_uniqueness_of :value1, :value2, :value3, :allow_nil => true I think I can use :unless to check whether the value is either "p" or "d", however I can't figure out how. I guess I am trying to combine validates_uniqueness_of with validates_inclusion_of. Any suggestions?

• Getting data from a ListView into an array

  - by Joe

  I have a ListView control on my form set up like this in details mode: What I would like to do, is get all the values of the data cells when the user presses the Delete booking button. So using the above example, my array would be filled with this data: values(0) = "asd" values(1) = "BS1" values(2) = "asd" values(3) = "21/04/2010" values(4) = "2" This is my code so far: Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim items As ListView.SelectedListViewItemCollection = _ Me.ManageList.SelectedItems Dim item As ListViewItem Dim values(0 To 4) As String Dim i As Integer = 0 For Each item In items values(i) = item.SubItems(i).Text i = i + 1 Next End Sub But only values(0) gets filled with the first data cell of the selection (in this case "asd") and the rest of the array entries are blank. I have confirmed this with a breakpoint and checked the array entries myself. I'm REALLY lost on this, and have been trying for about an hour now. Any help would be appreciated, thanks :) Also please note that there can only be one row selection at once. Thanks.

• C++: Best text accumulator

  - by MInner

  Text gets accumulates piecemeal before being sent to client. Now we use own class that allocates memory for each piece as char massive. (Anyway, works like char[][] + std::list<char*>). Then we build the whole string, convert it into std::sting and then create boost::asio::streambuf using it. That's slow enough, I assume. Correct me if I'm wrong. I know, in many cases simple FILE type from stdio.h is used. How does it works? Allocates memory at every write into it. So, is it faster and is there any way to read into boost::asio::streambuf from FILE?

• Possible relationship between PHP Mailer and Mailer-Daemon

  - by XGreen

  Hi, I am using the PHPMailer Class from a website which sends confirmation of the user ajax upload to my client. This uses the mail.myclient.com SMTP Host. This is the same SMTP Host that my client uses for his outlook to check his emails. This email from the website gets sent without errors although I have received two emails from my client regarding Mail delivery failed: returning message to sender for the same address I have used to send confirmation emails out from. Can these two issues be related? Do I need to provide more info? Thanks a bunch!

• .NET WebService IPC - Should it be done to minimise some expensive operations?

  - by Kyle

  I'm looking at a few different approaches to a problem: Client requests work, some stuff gets done, and a result (ok/error) is returned. A .NET web service definitely seems like the way to go, my only issue is that the "stuff" will involve building up and tearing down a session for each request. Does abstracting the "stuff" out to an app (which would keep a single session active, and process the request from the web service) seem like the right way to go? (and if so, what communication method) The work time is negligible, my concern is the hammering the transaction servers in question will probably get if I create/drop a session for each job. Is some form of IPC or socket based communication a feasible solution here? Thoughts/comments/experiences much appreciated. Edit: After a bit more research, it seems like hosting a WCF service in a Windows Service is probably a better way to go...

• [IE 7/8] Loading HTML content in via Javascript nulls my <title> tag in some instances

  - by Simon

  This is an Explorer only problem and the symptoms are: I have links that when clicked will load in HTML chunks (none of which contain html header tags) using javascript. The html chunks are placed in various <div>s around the page, perhaps 3 different places with 3 different chunks brought in via javascript. When these chunks load in the <title> tag of the page gets set to <title></title> for some unknown (to me) reason. I've used the IE developer toolbar to confirm this by inspecting the DOM tree. I have other pages that do similar things but it does not seem to be a problem there.

• CSS: set font weight depending on fallback font

  - by mikez302

  I am trying to set the font-weight for an element based on the font that gets chosen. For example, I may be trying to do something like this: h1 { font-family: Arial Narrow, Impact, sans-serif; font-weight: ?; } Let's say I want the font-weight to be "bold" if the user has Arial Narrow installed on their system, but "normal" if the browser has to use Impact, and maybe "bold" if the user's system has neither of those fonts. Is this possible? If so, how would I go about doing this?

• BDD-testing using a UI driver (e.g. Selenium for a web-application)

  - by jonathanconway

  Can BDD (Behavior Driven Design) tests be implemented using a UI driver? For example, given a web application, instead of: Writing tests for the back-end, and then more tests in Javascript for the front-end Should I: Write the tests as Selenium macros, which simulate mouse-clicks, etc in the actual browser? The advantages I see in doing it this way are: The tests are written in one language, rather than several They're focussed on the UI, which gets developers thinking outside-in They run in the real execution environment (the browser), which allows us to Test different browsers Test different servers Get insight into real-world performance Thoughts?

• ipod touch crashing after uploading app to device

  - by MaKo

  hi, I installed a new device (the second out of the 100), on xcode, an iPod touch but when I upload the app, the iPod crashes, apple logo shows, and gets frozen for a while, and then resusitates, in the xcode, I get the message on console: The Debugger has exited due to signal 15 (SIGTERM).

(in MyApp-info.plist, in bundle identifier, I have: com.yourcompany.${PRODUCT_NAME:rfc1034identifier} havent changed this, is this a problem?? 1.b. I used that conf to upload to an iPad with no problem?? Do the apps play normally sounds *.m4a, in the simulator it works!, not in the iPod, is this due to the crash or not? Thank you,, edit Im using AudioToolbox framework, the question after 1.b is 2 in my editor, but appears as 1 in the post??

• Show extra info for Preference screens when CheckboxPreference summary field is not enough long?

  - by Pentium10

  I have situation when you can enabled/disable modules for my Android application. For this I use a CheckboxPreference screen. This is all good, but the summary field gets cut off if longer descriptions are added than 2 lines. Suppose I have 4-5 lines of description available for each module, I would like to display this in a helper window. I tried to bind a click event to the CheckboxPreference, but that fires for the whole line, so not only when the checkbox is clicked, and more, where ever you click on the line the checkbox is toggled. So now I am wondering if this can be fixed. So if the user needs more info, just taps the text and the helper opens up, and if want to toggle the settings it taps the checkbox. How would you do it? I am open to other ideas too, if they do work.

• How can I stop a default event when using a named function in addEvent?

  - by Rupert

  Normally, if I wish to stop a default event in mootools I can do this: $('form').addEvent('submit', function(e) { e.stop(); //Do stuff here } However, I don't like using an anonymous function in events because I often want to reuse the code. Lets say I have a validate function. I could do this: $('form').addEvent('submit', validate); which works fine until I want to stop the default event. validate obviously doesn't know what e is so I can't just do e.stop(). Also I've tried passing the event as a variable to validate but whenever I use a named function with parameters, the function gets called automatically on domready, rather than on the event firing. Even worse, an error is thrown when the event is fired: What am I doing wrong?

• how do i set up a load balanced Rails web server using mongrel, lighttpd and iis on windows 2003

  - by user91519

  I understand that this is not the perfect environment for doing this but please stick with me and help if you can... The set up I want to achieve is to have my rails application running on a windows 2003 server, using a pack of mongrels with lighttpd acting as the load balancer and IIS in front of it all passing client requests to lighttpd. first of all i've followed these instructions: deploying to iis on windows And I've managed to get the application to run, BUT if the client clicks on a link button the app bombs out with a 500 server error. If I just run against one of the mongrel servers, the the app behaves ok, so I think its lightpd. Its almost as if the lighttpd gets confused with multiple GET requests (i.e. multiple clicks) and bombs out. Any help on why i'm getting 500 errors would be helpful, thanks.

• How can invoke a shell to make a new environment to run a make inside another make?

• 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?

• Android - LinearLayout Horizontal with wrapping children

Any idea how this can be fixed?

• Suggest resources for learning Scheme.

  - by EmFi

  I'll be starting a new job soon where Scheme is heavily used. I currently do not know Scheme, but my employer assures me that is not a problem. Regardless I'd like to hit the ground running and have a working knowledge of the language before my start date. So I'm looking for good resources from which to learn Scheme. I have had minimal exposure to functional languages. Really only a small chunk of a course devoted to Haskell. But I have a strong background in procedural and OO and procedural languages. Before it gets requested by a commenter, I am competent with the following languages: C, C++, C#, Java, Perl, Python, and Ruby.
