• Newline not showing correctly in textbox

  - by TheGateKeeper

  I am loading a string from my database which among other things contains line breaks (\r\n). However, this isn't being rendered as a new line but instead as \r\n. If I type it directly in instead of loading it from a string, it works just fine but I need to be able to load it from a string. Any ideas? Edit: Upon closer inspection, it looks like the string is being returned as: Changed test7\\r\\nChanged test8\\r\\nChanged test9Changed test7 From the database. I tried running a .Replace(@"\\", @"\") on it but this had no effect at all. Any ideas?

• Form validation with optional File Upload field callback

  - by MotiveKyle

  I have a form with some input fields and a file upload field in the same form. I am trying to include a callback into the form validation to check for file upload errors. Here is the controller for adding and the callback: public function add() { if ($this->ion_auth->logged_in()): //validate form input $this->form_validation->set_rules('title', 'title', 'trim|required|max_length[66]|min_length[2]'); // link url $this->form_validation->set_rules('link', 'link', 'trim|required|max_length[255]|min_length[2]'); // optional content $this->form_validation->set_rules('content', 'content', 'trim|min_length[2]'); $this->form_validation->set_rules('userfile', 'image', 'callback_validate_upload'); $this->form_validation->set_error_delimiters('<small class="error">', '</small>'); // if form was submitted, process form if ($this->form_validation->run()) { // add pin $pin_id = $this->pin_model->create(); $slug = strtolower(url_title($this->input->post('title'), TRUE)); // path to pin folder $file_path = './uploads/' . $pin_id . '/'; // if folder doesn't exist, create it if (!is_dir($file_path)) { mkdir($file_path); } // file upload config variables $config['upload_path'] = $file_path; $config['allowed_types'] = 'jpg|png'; $config['max_size'] = '2048'; $config['max_width'] = '1920'; $config['max_height'] = '1080'; $config['encrypt_name'] = TRUE; $this->load->library('upload', $config); // upload image file if ($this->upload->do_upload()) { $this->load->model('file_model'); $image_id = $this->file_model->insert_image_to_db($pin_id); $this->file_model->add_image_id_to_pin($pin_id, $image_id); } } // build page else: // User not logged in redirect("login", 'refresh'); endif; } The callback: function validate_upload() { if ($_FILES AND $_FILES['userfile']['name']): if ($this->upload->do_upload()): return true; else: $this->form_validation->set_message('validate_upload', $this->upload->display_errors()); return false; endif; else: return true; endif; } I am getting the error Fatal error: Call to a member function do_upload() on a non-object on line 92 when I try to run this. Line 92 is the if ($this->upload->do_upload()): line in the validate_upload callback. Am I going about this the right way? What's triggering this error?

Also any effeciency improvements would be appreciated :)

• Print out the variable name objective-C

  - by vodkhang

  Continued from the last question here: Log method name in Obj-C . I just wondered if there is a way to print out the variable name as well. For example: NSString *name = "vodkhang"; NCLog(@"%@", name); and I hope that the output should be: name: vodkhang Just to summarize the previous post, currently, I can print out the class name, method name and the line number when I call NCLog(@"Hello World"); <ApplicationDelegate:applicationDidFinishLaunching:10>Hello world with #define NCLog(s, ...) NSLog(@"<%@:%d> %@", __FUNCTION__, __LINE__, [NSString stringWithFormat:(s), ##__VA_ARGS__])

• Extracting text from PDF with Poppler (C++)

  - by nico

  I'm trying to get my way through Poppler and its (lack of) documentation. What I want to do is a very simple thing: open a PDF file and read the text in it. I'm then going to process the text, but that doesn't really matter here. So... I saw the poppler_page_get_text function, and it kind of works, but I have to specify a selection rectangle, which is not very handy. Isn't there just a very simple function that would output the PDF text in order (maybe line by line?). Thank you Nicola

• Sql server management studio reporting "The semaphore timeout period has expired."

  - by nis-simonsen

  On our development sql server, executing any query containing more than approximately 700 characters stalls for about 10 seconds and then reports the following error: Msg 121, Level 20, State 0, Line 0 A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.) for example, this query select * from FooTable where id = ' (.. and then 700 spaces ..) ' fails fails with the timeout error while this one select * from FooTable where id = ' (.. and then 600 spaces ..) ' fails with the expected Msg 8169, Level 16, State 2, Line 1 Conversion failed when converting from a character string to uniqueidentifier. - immediately. Indeed, throwing any query, including random garbage at our dev sql server exhibits this behaviour, while any other sql server I have available acts as expected, so I would think that the query never actually gets to parsing on the server. I'm at a loss here - any hints?

• can anyone explain the why the the 1st example gets different results than the following 2

  - by klumsy

  $b = (2,3) $myarray1 = @(,$b,$b) $myarray1[0].length #this will be 1 $myarray1[1].length $myarray2 = @( ,$b ,$b ) $myarray2[0].length #this will be 2 $myarray[1].length $myarray3 = @(,$b ,$b ) $myarray3[0].length #this will be 2 $myarray3[1].length UPDATE I think on #powershell IRC we have worked it out, Here is another example that demonstrates the danger of breaking with the comma on the following line rather than the top line when listing multiple items in an array over multiple lines. $b = (1..20) $a = @( $b, $b ,$b, $b, $b ,$b) for($i=0;$i -lt $a.length;$i++) { $a[$i].length } "--------" $a = @( $b, $b ,$b ,$b, $b ,$b) for($i=0;$i -lt $a.length;$i++) { $a[$i].length } produces 20 20 20 20 20 20 -------- 20 20 20 1 20 20 I'm curious how people will explain this. I think i understand it now, but would have trouble explaining it in a concise understandable fashion, though the above example goes somewhat towards that goal.

• Java: file write on finalize method

  - by sowrov

  In my understanding a singleton object will destroy only when the application is about to terminate. So in C++ I write a Singleton class to log my application and in that Singleton logger's destructor I log the time when my application was terminated. Things worked perfectly in C++. Now I want to have that same logger in Java, as in java there is no destructor so I implemented the finalize method for that singleton logger. But it seem that finalize method actually never get called. So, I add that System.runFinalizersOnExit(true); line, somewhere in my code (though I know it is deprecated) and that finalize method get called every time before termination of the app. But still there is a problem! If I try to write anything on file in that finalize method, It does not work, though System.out work without any problem! :( Can you guys help me on this problem? Here is a sample code of what I am try to do: Singleton Logger Class: public class MyLogger { FileWriter writer; private MyLogger() { try { this.writer = new FileWriter("log.txt"); } catch (IOException ex) { } } public static MyLogger getInstance() { return MyLoggerHolder.INSTANCE; } private static class MyLoggerHolder { private static final MyLogger INSTANCE = new MyLogger(); } @Override protected void finalize () { try { super.finalize(); System.out.println("Here"); //worked correctly. this.writer.write(new Date().toString()+System.getProperty("line.separator")); this.writer.write("End"); this.writer.flush(); //does not work! this.writer.close(); } catch (Throwable ex) { } } public synchronized void log(String str) { try { this.writer.write(new Date().toString()+System.getProperty("line.separator")); this.writer.write(str+"\n"); this.writer.flush(); } catch (IOException ex) { } } } Main: public class Main { public static void main(String[] args) { System.runFinalizersOnExit(true); MyLogger logger = MyLogger.getInstance(); logger.log("test"); } }

• Using Assert to compare two objects

  - by baron

  Hi everyone, Writing test cases for my project, one test I need is to test deletion. This may not exactly be the right way to go about it, but I've stumbled upon something which isn't making sense to me. Code is like this: [Test] private void DeleteFruit() { BuildTestData(); var f1 = new Fruit("Banana",1,1.5); var f2 = new Fruit("Apple",1,1.5); fm.DeleteFruit(f1,listOfFruit); Assert.That(listOfFruit[1] == f2); } Now the fruit object I create line 5 is the object that I know should be in that position (with this specific dataset) after f1 is deleted. Also if I sit and debug, and manually compare objects listOfFruit[1] and f2 they are the same. But that Assert line fails. What gives?

• how to get files as they are added to a remote server

  - by Jordan

  I am using a bash script (below) on a remote server (so far using ssh to connect) to execute a python script that downloads a lot of pdf files one at a time (getting the download locations from a text file with the URL's) in a loop. I would like to move the files from the remote server to my local computer as they are downloaded, and then delete the file from the remote server. Is there a way that I can expand my bash script to do this? Or are there alternatives for completing this task? while read line; do python python_script.py -l $line; done < pdfURLs.txt

• Nested for loop error with !null checking an element that doesn't exist

  - by Programatt

  I am currently using nested for loops in a 2D array of size 4,2. When I run my program, I get index out of bounds Exception on the following line else if (state[i][j+1] != null && state[i][j].getFlash() <= state[i][j].getCycleLength() && state[i][j+1].getCycleLength() == state[i][j].getCycleLength()){ } It says the index out of bounds is 2. I would understand the error if I wasn't checking to see if [i][j+1] wasn't null, but I don't understand the exception with the check? I tried moving around the !null check but the program still fails on this line. Any help would be greatly appreciated. Stack trace: Exception in thread "Timer-0" java.lang.ArrayIndexOutOfBoundsException: 2 at NatComp.data$1.run(data.java:67) at java.util.TimerThread.mainLoop(Timer.java:512) at java.util.TimerThread.run(Timer.java:462)

• Objective-c pointer assignment and reassignment dilema

  - by moshe

  Hi, If I do this: 1 NSMutableArray *near = [[NSMutableArray alloc] init]; 2 NSMutableArray *all = [[NSMutableArray alloc] init]; 3 NSMutableArray *current = near; 4 current = all; What happens to near? At line 3, am I setting current to point to the same address as near so that I now have two variables pointing to the same place in memory, or am I setting current to point to the location of near in memory such that I now have this structure: current - near - NSMutableArray The obvious difference would be the value of near at line 4. If the former is happening, near is untouched and still points to its initial place in memory. If the latter is happening,

• How can I make this REGEX cleaner?

  I have this regex I made to compare OS names to a line in a VMX file. It started out as seperate elsif statments but I ended up making into a single if statment. Anyhow here is the code, I am trying to find a way to make the code cleaner but it put each match on a seperate line it no longer works. elsif ($vmx_file =~ m/guestOSAltName\s+=\s"Microsoft\sWindows\sServer\s2003,Web\sEdition"|"Microsoft\sWindows\sSmall\sBusiness\sServer\s2003"|"Microsoft\sWindows\s2000\sAdvanced\sServer"|"Microsoft\sWindows\s2000\sServer"|"Microsoft\sWindows\s2000\sProfessional"|"Microsoft\sWindows\s98"|"Microsoft\sWindows\s95"|"Microsoft\sWindows\sNT\s4"/) { $virtual_machines{$vm}{"Architecture"} = "32-bit";

• Two collections and a for loop. (Urgent help needed) Checking an object variable against an inputted

  - by Elliott

  Hi there, I'm relatively new to java, I'm certain the error is trivial. But can't for the life of me spot it. I have an end of term exam on monday and currently trying to get to grips with past papers! Anyway heregoes, in another method (ALGO_1) I search over elements of and check the value H_NAME equals a value entered in the main. When I attempt to run the code I get a null pointer exception, also upon trying to print (with System.out.println etc) the H_NAME value after each for loop in the snippet I also get a null statement returned to me. I am fairly certain that the collection is simply not storing the data gathered up by the Scanner. But then again when I check the collection size with size() it is about the right size. Either way I'm pretty lost and would appreciate the help. Main questions I guess to ask are: from the readBackground method is the data.add in the wrong place? is the snippet simply structured wrongly? oh and another point when I use System.out.println to check the Background object values name, starttime, increment etc they print out fine. Thanks in advance.(PS im guessing the formatting is terrible, apologies.) snippet of code: for(Hydro hd: hydros){ System.out.println(hd.H_NAME); for(Background back : backgs){ System.out.println(back.H_NAME); if(back.H_NAME.equals(hydroName)){ //get error here public static Collection<Background> readBackground(String url) throws IOException { URL u = new URL(url); InputStream is = u.openStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader b = new BufferedReader(isr); String line =""; Vector<Background> data = new Vector<Background>(); while((line = b.readLine())!= null){ Scanner s = new Scanner(line); String name = s.next(); double starttime = Double.parseDouble(s.next()); double increment = Double.parseDouble(s.next()); double sum = 0; double p = 0; double nterms = 0; while((s.hasNextDouble())){ p = Double.parseDouble(s.next()); nterms++; sum += p; } double pbmean = sum/nterms; Background SAMP = new Background(name, starttime, increment, pbmean); data.add(SAMP); } return data; } Edit/Delete Message

• Python and sqlite3 - importing and exporting databases

  I'm trying to write a script to import a database file. I wrote the script to export the file like so: import sqlite3 con = sqlite3.connect('../sqlite.db') with open('../dump.sql', 'w') as f: for line in con.iterdump(): f.write('%s\n' % line) Now I want to be able to import that database. I tried: import sqlite3 con = sqlite3.connect('../sqlite.db') f = open('../dump.sql','r') str = f.read() con.execute(str) but I'm not allowed to execute more than one statement. Is there a way to get it to run a .sql script directly?

• Script to fix broken lines in a .txt file?

  - by Gravitas

  Hi, I'd love like to read books properly on my Kindle. To achieve my dream, I need a script to fix broken lines in a txt file. For example, if the txt file has this line: He watched Kahlan as she walked with her shoulders slumped down. ... then it should fix it by deleting the newline before the word "down": He watched Kahlan as she walked with her shoulders slumped down. So, fellow programmers, whats (a) the easiest way to do this and (b) the best language? p.s. The solution will involve searching for a lowercase letter in column 1, and deleting the newline before it to stitch the lines together. There are 1.2 million occurrences of this "rogue line break" in the novel I am trying to fix.

• Saving a movie generated with Jython/JES on local disk

  I made an autogenerated movie clip using JES (Jython Environment for Students). I can play it without any problem using playMovie(), but I can't figure out how to have it saved physically on disk. The full script is located here. ... movie = synthesizeFrameAndCreateMovie("D:\\FOLDER") print movie writeQuicktime(movie,"D:\\FOLDER\\movie.mov", 30) [LINE 35] #playMovie(movie) I get this error when calling the function writeQuicktime(): >>> ======= Loading Progam ======= Movie, frames: 60 The error was: Index: 0, Size: 0 I wasn't able to do what you wanted. The error java.lang.IndexOutOfBoundsException has occured Please check line 35 Note : I also tried the function writeAVI(), with the exact same result. This error sounds like a java bug in Jython/JES library. I am running JES under Windows 7 and have all the common Quicktime and AVI codex installed as well as the QTjava library in my jre... Any brilliant idea ? EDIT : Also tried the Linux version with same result for both QuickTime and AVI...

• HTML: Fill available width

  - by Thanatos

  What I'm trying to do is this: XXX Some text here YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY ZZZZZZZZZ Body body body Sidebar! Body body body Sidebar! Body body body Sidebar! X, Y, and Z are images (3 images total). Y can stretch along the X axis, and does so above, to fill the available space. (But doesn't cause "Some text here" to get squished and start breaking into multiple lines) I'd like to keep the "Some text here" part in one line. A line breaking here will not end happily. Is this possible, or should I simplify the layout around HTML?
