• Sending changing params through periodically_call_remote

  - by seaneshbaugh

  I'm using periodically_call_remote to update a portion of a page that contains a list of objects. I send along with the url a param containing the created_at date for the most recent object in the database. The action that is called then get all the objects that have been created since then and renders a partial which displays them at the top of the list. The problem is that I can't seem to figure out how to make it so that the next time periodically_call_remote triggers it sends along the created_at date for the new most recent object (if there is one). I tried putting the periodically_call_remote inside the partial that is being rendered but that caused all sorts of problems (http://www.ruby-forum.com/topic/101614 explains why you shouldn't do that). Is there some way I can make periodically_call_remote send along a new param each time it's called? As it stands right now it just sends the same one over and over which means that new objects get rendered more than once.

• SSIS process files from folder

  - by RT

  Background: I've a folder that gets pumped with files continuously. My SSIS package needs to process the files and delete them. The SSIS package is scheduled to run once every minute. I'm picking up the files in ascending order of file creation time. I'm building an array of files and then processing-deleting them one at a time. Problem: If an instance of my package takes longer than one minute to run, the next instance of the SSIS package will pick up some of the files the previous instance has in its buffer. By the time the second instance of teh package gets around to processing a file, it may already have been deleted by the first instance, creating an exception condition. I was wondering whether there was a way to avoid the exception condition. Thanks.

• Leave approval hierarchy in openERP

  - by Miraj Baldha

  I am new to openERP and facing issues with HR module. I have this structure Project Manager-Team Leader-Developer Team Leader is a manager of developer Project Manager is manager of Team Leader. So, if developer asks for leave then first leave request should be sent to Team Leader (mail notification to Team Leader and Project Manager) and once TL approves Leave then automaitically request sent to Project Manager for second level approval. With openERP 6.1, there is no possibility to approve leave by Team Leader unless and until Team Leader is specified as a HR manager which is inappropriate. Anybody have any solution then let me know. Thanx..

• C++ Linked List - Reading data from a file with a sentinel

  - by Nick

  So I've done quite a bit of research on this and can't get my output to work correctly. I need to read in data from a file and have it stored into a Linked List. The while loop used should stop once it hits the $$$$$ sentinel. Then I am to display the data (by searching by ID Number[user input]) I am not that far yet I just want to properly display the data and get it read in for right now. My problem is when it displays the data is isn't stopping at the $$$$$ (even if I do "inFile.peek() != EOF and omit the $$$$$) I am still getting an extra garbage record. I know it has something to do with my while loop and how I am creating a new Node but I can't get it to work any other way. Any help would be appreciated. students.txt Nick J Cooley 324123 60 70 80 90 Jay M Hill 412254 70 80 90 100 $$$$$ assign6.h file #pragma once #include <iostream> #include <string> using namespace std; class assign6 { public: assign6(); // constructor void displayStudents(); private: struct Node { string firstName; string midIni; string lastName; int idNum; int sco1; //Test score 1 int sco2; //Test score 2 int sco3; //Test score 3 int sco4; //Test score 4 Node *next; }; Node *head; Node *headPtr; }; assign6Imp.cpp // Implementation File #include "assign6.h" #include <fstream> #include <iostream> #include <string> using namespace std; assign6::assign6() //constructor { ifstream inFile; inFile.open("students.txt"); head = NULL; head = new Node; headPtr = head; while (inFile.peek() != EOF) //reading in from file and storing in linked list { inFile >> head->firstName >> head->midIni >> head->lastName; inFile >> head->idNum; inFile >> head->sco1; inFile >> head->sco2; inFile >> head->sco3; inFile >> head->sco4; if (inFile != "$$$$$") { head->next = NULL; head->next = new Node; head = head->next; } } head->next = NULL; inFile.close(); } void assign6::displayStudents() { int average = 0; for (Node *cur = headPtr; cur != NULL; cur = cur->next) { cout << cur->firstName << " " << cur->midIni << " " << cur->lastName << endl; cout << cur->idNum << endl; average = (cur->sco1 + cur->sco2 + cur->sco3 + cur->sco4)/4; cout << cur->sco1 << " " << cur->sco2 << " " << cur->sco3 << " " << cur->sco4 << " " << "average: " << average << endl; } }

• How do I avoid nesting forms when offering inline editing of lists with checkboxes for mass updates.

  - by adam

  A lot of sites offer the ability to edit lists of items inline as well as allowing multiple items to be selected via checkboxes and have an action performed all at once e.g. delete, mark as spam etc. But how do you implement this without violating html rules. I need one form for the checkboxes with individual submit_tags for the mass actions. But after a user clicks on an item in the list, another form via Ajax will be inserted within the checkbox form. How do I avoid doing this? I'm using rails and jQuery.

• how to copy char * into a string and visa versa

  - by user295030

  If i pass a char * into a function. I want to then take that char * convert it to a std::string and once I get my result convert it back to char * from a std::string to show the result. I don't know how to do this for conversion ( I am not talking const char * but just char *) I am not sure how to manipulate the value of the pointer I send in. so steps i need to do take in a char * convert it into a string. take the result of that string and put it back in the form of a char * return the result such that the value should be available outside the function and not get destroyed. If possible can i see how it could be done via reference vs a pointer (whose address I pass in by value however I can still modify the value that pointer is pointing to. so even though the copy of the pointer address in the function gets destroyed i still see the changed value outside. thanks!

• make javascript repeat for each row in a view

  - by Kathy Chavez

  I have created a view in Drupal. I"m using javascript to modify css in each row. The script runs on the first row, but does not make the changes on the rest of rows from the view. This is the script: <script language="javascript" type="text/javascript"> window.onload = floatbr; function floatbr() { var f = document.getElementById('firstright') // Get div element var s = document.getElementById('secondright') // Get div element var w = document.getElementById('catwrapper') // Get div element var sh = s.offsetHeight // secondright div height var wh = w.offsetHeight // catwrapper div height f.style.height = wh - sh + 'px'; } </script> I'm using it from this page: http://agsone.100webcustomers.com/floatbottom.php having the script in the page once does not do the trick. having the script in the view footer and repeating the script does not work. THanks! link to fiddle with html, css & js: http://jsfiddle.net/Vvjku/

• Prolog - Finding the current directory, relative directory for 'tell' predicate

  - by Bharat

  I'm having trouble trying to figure out how to get prolog to spit out a text file where I want it to. I'm currently doing a bunch of operations and then using tell('output.txt') to record the output. Now the problem is that when I do this, it creates this file in the SWI \bin\ folder. I was wondering if there's a way to make it create this file in the directory containing the actual .pl file. So even if the file was moved (and it will be), the text file gets created right where the source file is. Long story short, is there a way to get the location of the source file once the source file has been consulted? Many Thanks!

• Enable Query Strings in Code Igniter

  - by tarnfeld

  Hey, I am trying to implement Twitter's OAuth into my Code Igniter web application at which the callback URL is /auth/ so once you have authenticated with Twitter you are taken to /auth/?oauth_token=SOME-TOKEN. I want to keep the nice clean URL's the framework provides using the /controller/method/ style of URL but I want to enable query strings as well, there will only ever be one name of the data oauth_token so it's ok if it has to be hard coded. Any ideas? I have tried tons of the things people are saying to do, but none work :( PS: I'm using the .htaccess method of URL rewriting.

• Removing all installed Gems and starting over

  - by Dave Long

  I recently started learning Ruby and Ruby on Rails, and have watched a plethora of getting started materials. I have been finding lately that I keep getting errors where gems won't install or they will be installed but they can't be used for some reason, and I have decided that I want to remove everything down to once again just having Ruby installed and start over with the installation. One training video had me install most of my gems with RVM, so I don't know if that changes anything. So in short my question is "How to I get rid of RVM, Rubygems, and all installed Gems so that I can start over with just Ruby?" Edit: I am on Mac OS 10.6

• Prevent Jcarousel from resetting to beginning position on page postback?

  - by lbholland

  I have a nice looking jarousel running from an asp:listview element, with asp:imagebuttons for the images. When clicked, the images in the carousel send the image id to querystring, and the new page is loaded with a larger version of the image and some asp:labels are filled in to describe the image. It looks and works great, except once the page reloads the jcarousel resets to original position, which is confusing to the user. What's the best way to prevent this? I tried using an UpdatePanel but couldn't figure out how to pass the querystring variable with the partial page update. I could pass the variable in a hidden field, but this wouldn't be very SEO friendly.

• How do I change the default format of log messages in python app engine?

  - by dazed-n-confused

  I would like to log the module and classname by default in log messages from my request handlers. The usual way to do this seems to be to set a custom format string by calling logging.basicConfig, but this can only be called once and has already been called by the time my code runs. Another method is to create a new log Handler which can be passed a new log Formatter, but this doesn't seem right as I want to use the existing log handler that App Engine has installed. What is the right way to have extra information added to all log messages in python App Engine, but otherwise use the existing log format and sink?

• How to do steps of an API through CLI

  - by Dolphin

  I'm using Audiveris API to generate xml(MusicXML) file once the sheetmusic(e.g. pdf/img file) is being input (i.e. When I give the sheet music (pdf file) location, to generate the xml file out of it (in another location)). Audiveris has its own GUI to do this. But can I do this process of sheetmusic-to-xml without using their GUI, but only from the CLI? If so how may I approach it? And also if so - is there a possibility to make it work in CLI - using Java code (say to invoke steps for API to occur in the CLI using Java Code)? I managed to open the GUI by opening the jar file from CLI. But I need to know whether there's a possibility to carry out the sheetmusic(say pdf)-to-xml process without using their GUI, but only through CLI? Greatly appreciate any help or guidance Thanks in advance

• sbt: "test" works "test:run" not

  - by Martin

  I try to establish a build pipeline on Jenkins with a Play(2.0.2) project. As I want to just build the sources once and use the classes for downstream builds, I now have created a "compile"-job, that runs "sbt test:compile". That works so far. The next job should then just run the compiled tests. If I use "sbt test" it works as expected, but compiles the sources again. But if I try to run "sbt test:run" it says: [info] Loading project definition from ~/myproject/project [info] Set current project to myproject (in build file: ~/myproject/) java.lang.RuntimeException: No main class detected. at scala.sys.package$.error(package.scala:27) [error] {file:~/myproject/test:run: No main class detected. The same happens locally. I can run "sbt test" but not "sbt test:run". Same error. Is there someone who can point me to the right direction?

• Formatting a query to enumerate through 2 different datatables

  - by boiler1974

  I have 2 datatables sendTable and recvTable They both have identical column names and numbers of columns "NODE" "DSP Name" "BUS" "IDENT" "STATION" "REF1" "REF2" "REF3" "REF4" "REF5" "REF6" "REF7" "REF8" I need to compare these 2 tables and separate out the mismatches I only need to check Columns 3-11 and Ignore col 1 and 2 I tried at first removing the 2 columns and then loop thru row by row and return matches and mismatches but the problem with this approach is that I no longer have the "NODE" and "DSP Name" associated with the row when I finalize my results So I need help with a query Here is my attempt var samerecordQuery = from r1 in sendTable.AsEnumerable() where r1.Field<int>("BUS").Equals(from r2 in recvTable.AsEnumerable() where r2.Field<int>("BUS")) this obviously doesn't work so how do I format the query to say from r1 cols[3-11] equals r2 cols [3-11] and once I have this I can use the except to pull out the mismatches

• Fade animation UITableViewCell

  - by Tomas

  Hi everyone, I have a UITableViewController that populates a UITableView with some data that I pull off the net. The data for each cell consists also of an image used as background, which I'm downloading in a separated NSOperation added to a NSOperationQueue with a MaxConcurrentOperationCount set to 4. As long as the image is not downloaded I'm showing a generic placeholder which I would like to replace (fading out/fading in) with the downloaded image once it's being successfully downloaded. I'm using the following code placed inside the cellForRowAtIndexPath of the UITableViewController. [UIView beginAnimations:@"fade" context:nil]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:3.0]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; cell.placeholderUIImage.alpha = 0.0; cell.backgroundUIImage.alpha = 1.0; [UIView commitAnimations]; This is unfortunately just working randomly for a couple of rows, since for the most the background image is set instantly, as if the animation started on one cell would have been "overwritten" by the next call of beginAnimations.

• Looping through values in NSDictionary throws fault

  - by jud

  I have a plist file that I am loading into an NSDictionary *setDictionary that contains a set of fields, pictureDesc1, pictureDesc2, etc. Once the NSDictionary is loaded, I can retrieve a value using [setDictionary objectForKey:@"pictureDesc1"]; But I cannot do a loop like this: for (int i=1; i<=numberOfPictures; i++) { NSString *keyName = [NSString stringWithFormat:@"pictureDesc%d",i]; NSString *description = [NSString stringWithFormat:@"%@", [setDictionary objectForKey:keyName]]; } Is there a different way to dynamically call keys from within an NSDictionary?

• How to set breakpoint in inline Javascript in Google Chrome browser for linux?

  When I open Developer Tools in Google Chrome, I see all kinds useless crap like Profiles, Timelines, not to mentions Audits but basic functionality like being able to set breakpoint both in js files and within html javascript code is missing!. I tried to use javascript Console which itself is buggy ( like when once it encounter JS error, cannot get out of it unless refresh the whole page useless when ajax is involved). I am surprised google engineers still have not figured this out if these features still not available. If they are and there is some twisted way to do this, can some one help?

• What is the best data structure and algorithm for comparing a list of strings?

  - by Chiraag E Sehar

  I want to find the longest possible sequence of words that match the following rules: Each word can be used at most once All words are Strings Two strings sa and sb can be concatenated if the LAST two characters of sa matches the first two characters of sb. In the case of concatenation, it is performed by overlapping those characters. For example: sa = "torino" sb = "novara" sa concat sb = "torinovara" For example, I have the following input file, "input.txt": novara torino vercelli ravenna napoli liverno messania noviligure roma And, the output of the above file according to the above rules should be: torino novara ravenna napoli livorno noviligure since the longest possible concatenation is: torinovaravennapolivornovilligure Can anyone please help me out with this? What would be the best data structure for this?

• Adobe Livecycle Designer 7 Text Field Issue

  - by MachinationX

  I have a form in a large box, to be filled in by the user with up to 2500 characters. Currently, the cursor starts in the vertical center of the box and I would like: a) The cursor to start at the top left of the field instead of the middle left, so that there is no whitespace above the user's entered text. or b) Somehow enabling a field that expands to fit its text to expand as the text is being entered. As far as I can tell, text fields set to expand to fit the text inside only expand once the user has taken their cursor off the field. Thanks for your help!

• EJB3.1 Remote invocation - is it distributed automatically? is it expensive?

  - by Hank

  I'm building a JEE6 application with performance and scalability in the forefront of my mind. Business logic and JPA2-facade is held in stateless session beans (EJB3.1). As of right now, the SLSBs implement only @Remote-interfaces. When a bean needs to access another bean, it does so via RMI. My reasoning behind this is the assumption that, once the application runs on a bunch of clustered application servers, the RMI-part allows the execution to be distributed across the whole cluster automagically. Is that a correct assumption? I'm fine with dealing with the downsides of that (objects lose entityManager session, pass-by-value), at least I think so. But I am wondering if constant remote invocation isn't adding more load then necessary.

• iPhone Mobile Safari File System Access

  - by Jon Smallberries

  Is it possible to write to a file in a native iPhone application and have a Safari browser read from that file after having the browser opened from the native app? Alternatively (and this would be great!), would it be possible to launch a mobile Safari webapp from a native iPhone app, and have that application access the OS 3.0 External Accessory Framework? My assumption is no... Basically, I have a functioning iPhone app that wraps a simple mobile Safari webapp, but I'd like to utilize the external accessory framework once I have launched the Safari webapp from the iPhone app...

• AMF through a BinarySocket written in .net

  Hi All, I have a windows service behaving as a Binary Socket sending data to flex applications. Once I try to send strings or int's or any other native data-type, everything is working great.

Meaning, I have a class called User, I want to fill it with data and send it to the client, there I want it to be mapped to an object on the client. How can I achieve this?
