  • Need help with UISearchBar and NSString

    - by guydor
    Hi, I would like to make an if command that checks the value of my UISearchBar in that way if the value of the UISearchBar is equals to " " or multiple spaces without words and chars, an alert will popup. Well, I don't need help with the creation of the alert but I do need help with the if command and the spaces. I know how to do it with multiple "if" command but I want with only 1. Thanks!

  • How can I determine a file extension given a file name in LaTeX?

    - by Frank
    I am attempting to write a LaTeX package which leverages the minted package's \inputminted command. My \mycommand command takes two parameters, the first being a path to a file, and I want to pass the file's extension to the \inputminted command: \newcommand\mycommand[2]{ \inputminted{#1}{...} } Note that the above won't work since the full path is passed to \inputminted. Example: \mycommand{/path/to/Test.java}{blah} should invoke \inputminted{java}{...}

  • Unit testing a text index

    - by jplot
    Consider a text index such as a suffix tree or a suffix array supporting Count queries (number of occurrences of a pattern) and Locate queries (the positions of all the occurrences of a pattern) over a given text. How would you go about unit testing such a class ? What I have in mind is to generate a big random string then extract a random substring from this big string and compare the results of both queries with naive implementations (such as string::find). Another idea I have is to find the most frequent substring of length l appearing in the original string (using perhaps a naive method) and use these substrings for testing the index. This isn't the best way, so what would be a good design of the unit tests for a text index ? In case it matters, this is in C++ using google test.

  • What is the flag to show the nesting of views in a Mac app?

    - by theMikeSwan
    I have just spet the last few hours trying to find the flag to use in Terminal to launch an app with the colored outlines around the various view elements to show how they are nested. I know that Matt Gemmell covered it during the Cocoa Face Off session of NSConference 2009 (at about the 13minute mark in the video). Unfortunately I can't actually read what he types and he doesn't speak the exact command. I know it has to be in the Apple docs somewhere but the search system is currently not being of any use. It looks like her just adds -showAllViews YES to the end of the command to open TextEdit but that command has no effect in 10.6.6. I have also tried every other capitalization I can think of as well as using view instead of views. Every command opens TextEdit just fine but doesn't show the colored outlines.

  • Killing a script launched in a Process via os.system()

    - by L.J.
    I have a python script which launches several processes. Each process basically just calls a shell script: from multiprocessing import Process import os import logging def thread_method(n = 4): global logger command = "~/Scripts/run.sh " + str(n) + " >> /var/log/mylog.log" if (debug): logger.debug(command) os.system(command) I launch several of these threads, which are meant to run in the background. I want to have a timeout on these threads, such that if it exceeds the timeout, they are killed: t = [] for x in range(10): try: t.append(Process(target=thread_method, args=(x,) ) ) t[-1].start() except Exception as e: logger.error("Error: unable to start thread") logger.error("Error message: " + str(e)) logger.info("Waiting up to 60 seconds to allow threads to finish") t[0].join(60) for n in range(len(t)): if t[n].is_alive(): logger.info(str(n) + " is still alive after 60 seconds, forcibly terminating") t[n].terminate() The problem is that calling terminate() on the process threads isn't killing the launched run.sh script - it continues running in the background until I either force kill it from the command line, or it finishes internally. Is there a way to have terminate also kill the subshell created by os.system()?

  • Sql query builder c# for windows mobile

    - by pdiddy
    I'm building a windows mobile app. And using SqlCe. I'm looking for a good sql query builder. So instead of writing "SELECT COLUMNS FROM TABLE WHERE etc... Is there a good free library that can build this sort of query? EDIT: You know when you write your code with ADO.net something like this SqlCeCommand command = new SqlCeCommand(Connection); command.CommandText = "SELECT * FROM Orders WHERE customerId = @customerId"; Well i'm looking for some library that could build that SELECT statement using classes instead of writing it through string. So something like: SqlCeCommand command = new SqlCeCommand(Connection); SqlQueryBuilder query = new SqlQueryBuilder(); query.Table = "Orders"; query.AddWhere("customerId", myValue) command.CommandText = query.toString(); Something like that .... so a class that will build the query..

  • issue running a batch script to kill a process

    - by user657064
    I am using the following script on a command line to kill a hypothetical notepad process (using a Korn shell in Windows XP, if that matters): kill $(tasklist | grep -i notepad.exe | awk '{print 2}') Now I take this line, and put it into a batch file c:\temp\testkill.bat, thinking that I should just as well be able to kill the process by running the batch file. However, when I run the batch file, I get the following awk error about unbalanced parentheses: C:/Temp ./testkill.bat C:\Tempkill $(tasklist | grep -i notepad.exe | awk '{print $2}') awk: unbalanced () Context is: {print $2}) <<< C:/Temp So I'm baffled as to why I am getting this error about unbalanced parentheses when I run this script via a batch file, but have no issues when I run the command directly from the command line? (Btw, I'm not necessarily tied to this way of killing a process - as a total noob to shell scripting, I am additionally wondering why if I write the following on the command line: tasklist | grep -i notepad.exe | awk '{print $2}' | kill the process ID that comes out of the tasklist/grep/awk calls doesn't seem to properly get piped to kill...)

  • jQuery code not executed

    - by Jan-Frederik Carl
    Hello, I would like to rephrase my previous question which no one could answer. My problem is that a jQuery-script does not execute a command though it "runs" it. I can see it in the debug mode where the debugger hits the command. Nonetheless, the command is not executed.

  • Implemeting web-based autocomplete for structured input

    - by ravigad
    I am looking to implement web-based autocomplete for structured commands. So, for example, suppose I was trying to implement a web-based Windows command line with autocomplete, in such a case I would want to suggest all the available commands, then, once a user selects a command, all the options for that command, then if a user enters a switch (say '-' dash or '/' slash) then offer all the switches for that command and all the relevant values that can follow, and so on. All from the same text input box. If you have used version 4.0 of JIRA, I am thinking of something similar to the JQL search input box that they have implemented. I have not managed to find any tutorials that look at this scenario end-to-end (which is a shame, because it would be great to see more applications that do this). What I am looking for is some guidance on the steps needed to implement this solution: Do you have any experience implementing such a solution and if so what components did you use? Would you use a framework such as ANTLR to provide the available options to the end user? If not what would do? Sorry for raising such a general question, but my main problem is working out how the pieces fit together as opposed to, say, how to do autocomplete or how to parse/tokenize an input command...

  • Vim, how to scroll to bottom of a named buffer

    - by Gavin Black
    I have a vim-script which splits output to a new window, using the following command: below split +view foo I've been trying to find a way from an arbitrary buffer to scroll to the bottom of foo, or a setting to keep it defaulted to showing the bottom lines of the buffer. I'm doing most of this inside of a python block of vim script. So I have something like: python << endpython import vim import time import thread import sys def myfunction(string,sleeptime,*args): outpWindow = vim.current.window while 1: outpWindow.buffer.append("BAR") #vim.command("SCROLL TO BOTTOM OF foo") time.sleep(sleeptime) #sleep for a specified amount of time. vim.command('below split +view foo') thread.start_new_thread(myfunction,("Thread No:1",2)) endpython And need to find something to put in for vim.command("SCROLL TO BOTTOM of foo") line

  • cygwin sed substitution against commands in history

    - by Ira
    I couldn't find an answer for this exact problem, so I'll ask it. I'm working in Cygwin and want to reference previous commands using !n notation, e.g., if command 5 was which ls, then !5 runs the same command. The problem is when trying to do substitution, so running: !5:s/which \([a-z]\)/\1/ should just run ls, or whatever the argument was for which for command number 5. I've tried several ways of doing this kind of substitution and get the same error: bash: :s/which \([a-z]*\)/\1/: substitution failed

  • How to know from a bash script if the user abruptly closes ssh session

    - by Figo
    I have a bash script that acts as the default shell for a user loging in trough ssh. It provides a menu with several options one of wich is sending a file using netcat. The netcat of the embedded linux I'm using lacks the -w option, so if the user closes the ssh connection without ever sending the file, the netcat command waits forever. I need to know if the user abruptly closes the connection so the script can kill the netcat command and exit gracefully. Things I've tried so far: Trapping the SIGHUP: it is not issued. The only signal issued i could find is SIGCONT, but I don't think it's reliable and portable. Playing with the -t option of the read command to detect a closed stdin: this would work if not for a silly bug in the embedded read command (only times out on the first invocation)

  • Google Analytics: Track user usage and flow

    - by Quintin Par
    Can someone help to query Google analytics to track a specific user behavior and usage pattern? Currently I pass user id’s to GA as _setCustomVar(2, 'id', id, 1); This is session based. But I am yet to master how I can utilize this to view usage pattern & behavior for the passed id. Say, I need to understand the visualization flow for one id or the page view count for that id etc Rephrasing, can I filter all existing reports for a specific id that I can select?

  • How do I set up Array/List dependencies in code with Castle Windsor?

    - by SharePoint Newbie
    Hi, I have the following classes: class Repository : IRepository class ReadOnlyRepository : Repository abstract class Command abstract CommandImpl : Command { public CommandImpl(Repository repository){} } class Service { public Service (Command[] commands){} } I register them in code as follows: var container = new Container("WindsorCOntainer.config"); var container = new WindsorContainer(new XmlInterpreter("WindsorConfig.xml")); container.Kernel.Resolver.AddSubResolver(new ArrayResolver(container.Kernel)); container.AddComponent("repository", typeof(RentServiceRepository)); container.Resolve<RentServiceRepository>(); container.AddComponent("command", typeof(COmmandImpl)); container.AddComponent("rentService", typeof (RentService)); container.Resolve<RentService>(); // Fails here I get the message that "RentService is waiting for dependency commands" What am I doing wrong? Thanks,

  • How to figure out why ssh session does not exit sometimes?

    - by WilliamKF
    I have a C++ application that uses ssh to summon a connection to the server. I find that sometimes the ssh session is left lying around long after the command to summon the server has exited. Looking at the Centos4 man page for ssh I see the following: The session terminates when the command or shell on the remote machine exits and all X11 and TCP/IP connections have been closed. The exit status of the remote program is returned as the exit status of ssh. I see that the command has exited, so I imagine not all the X11 and TCP/IP connections have been closed. How can I figure out which of these ssh is waiting for so that I can fix my summon command's C++ application to clean up whatever is being left behind that keeps the ssh open. I wonder why this failure only occurs some of the time and not on every invocation? It seems to occur approximately 50% of the time. What could my C++ application be leaving around to trigger this?

  • Why is my Perl script that calls FTP all of a sudden failing?

    - by Mel
    I have a script that has been running for over a year and now it is failing: It is creating a command file: open ( FTPFILE, ">get_list"); print FTPFILE "dir *.txt"\n"; print FTPFILE "quit\n"; close FTPFILE; Then I run the system command: $command = "ftp ".$Server." < get_list | grep \"\^-\" >new_list"; $code = system($command); The logic the checks: if ($code == 0) { do stuff } else { log error } It is logging an error. When I print the $code variable, I am getting 256. I used this command to parse the $? variable: $exit_value = $? >> 8; $signal_num = $? & 127; $dumped_core = $? & 128; print "Exit: $exit_value Sig: $signal_num Core: $dumped_core\n"; Results: Exit: 1 Sig: 0 Core: 0 Thanks for any help/insight.

  • viewing files in python?

    - by Galilsnap
    I am creating a sort of "Command line" in Python. I already added a few functions, such as changing login/password, executing, etc., But is it possible to browse files in the directory that the main file is in with a command/module, or will I have to make the module myself and use the import command? Same thing with changing directories to view, too.

  • Android Bluetooth syncing

    - by Darryl
    I am connecting to a bluetooth enabled camera, and I am able to connect using the methods found in the BluetoothChat example. I need to send commands to the camera. The issue is that I also need to get a response BACK from the camera after I send the command in the first place. So basically I need to write a command and receive a response. However, the thing is that the commands sometimes don't generate a response. Even the documentation on the camera says that you "have to send the sync command as many as 25 times on power up before you will get a response." So I cannot just write a command and wait for a response, as the "read" function blocks the thread. If I have the read function in another thread, like the bluetooth chat example, there seems to be sync issues, i.e., if I issue a write command, how can I know that it is reading if that is happening in another thread? I did set a global variable to check for, but this seems "iffy" at best. So basically I need to write to the bluetooth and then attempt to read from it. However, I need to let that read timeout and if I haven't received a response, I need to write again until I get a response (or until it's tried a set number of times). I don't need the read function to be going all the time in the background. Any ideas? Thanks in advance for your time.

  • A beginner question on passthru() function in PHP

    - by Robert
    Hi all, I've used the following code to do an XSLT translation in PHP and save the result SVG file into a sub folder: $command = $java . $saxon . $target2 . ' ' . $xsl2.' '.$param; ob_start(); passthru($command, $result); $content_grabbed=ob_get_contents(); ob_end_clean(); $info = pathinfo($_FILES['file']['name']); $file_name= basename($_FILES['file']['name'],'.'.$info['extension']); $myFile = "images/convert/".$file_name."_".$_POST["mydropdown"].".svg"; $fh = fopen($myFile, 'w') or die("can't open file"); fwrite($fh, $content_grabbed); fclose($fh); It does a very simple SVG to SVG transformation, and created the resulting SVG file. the $command is just a simple java -jar saxon.jar input.xml stylesheet java command. The current situation is ,the file gets created perfectly, however, the error gets shown in browser, probably because I inserted the "ob_start" before passthru() command. I am thinking of making use of an argument that comes with the saxon.jar, that is "-o output_file_name". Because the final purpose is not to display the resulting SVG to the browser, but instead creating an SVG file ,and provide the link to the user for downloading. Are there any better ways to handle this problem, I am still thinking about how to get rid of the result that gets shown in the browser that is sent by the "passthru()". Thanks in advance for suggestions!

  • How to avoid escaping by accident in PERL using system()?

    - by Brian
    I want to run some commands using the system() command, I do this way: execute_command_error("trash-put '/home/$filename'"); Where execute_command_error will report if there was an error with whatever system command it ran. I know I could just unlink the file using Perl commands, but I want to delete stuff using trash-put as it's a type of recycling program. My problem is that $filename will sometimes have apostrophes, quotes, and other weird characters in it that mess up the system command or Perl itself.

  • Selectively parsing log files using Java

    - by GPX
    I have to parse a big bunch of log files, which are in the following format. SOME SQL STATEMENT/QUERY DB20000I The SQL command completed successfully. SOME OTHER SQL STATEMENT/QUERY DB21034E The command was processed as an SQL statement because it was not a valid Command Line Processor command. EDIT 1: The first 3 lines (including a blank line) indicate an SQL statement executed successfully, while the next three show the statement and the exception it caused. darioo's reply below, suggesting the use of grep instead of Java, works beautifully for a single line SQL statement. EDIT 2: However, the SQL statement/query might not be a single line, necessarily. Sometimes it is a big CREATE PROCEDURE...END PROCEDURE block. Can this problem be overcome using only Unix commands too? Now I need to parse through the entire log file and pick all occurrences of the pair of (SQL statement + error) and write them in a separate file. Please show me how to do this!
