  • [bash] Escape a string for sed search pattern

    - by Alexander Gladysh
    In my bash script I have an external (received from user) string, which I should use in sed pattern. REPLACE="<funny characters here>" sed "s/KEYWORD/$REPLACE/g" How can I escape the $REPLACE string so it would be safely accepted by sed as a literal replacement? NOTE: The KEYWORD is a dumb substring with no matches etc. It is not supplied by user.

  • Open link in new window with Jquery

    - by mtwallet
    Hi. I am trying to open a few links in a new window using Jquery rather than _blank so my html remains valid. My code looks like this: $(document).ready(function() { $('a[id="external-url"]').click(function(){ $(this).attr('target','_blank'); }); }); This works just fine except when the link is contained within html I have placed on the page using the Jquery load() method. Can anyone explain why and please help with a solution?

  • How to change a Window Owner using its handle

    - by Ricky AH
    I want to make a .NET Form as a TopMost Form for another external App (not .NET related, pure Win32) so it stays above that Win32App, but not the rest of the apps running. I Have the handle of the Win32App (provided by the Win32App itself), and I've tried Win32 SetParent() function, via P/Invoke in C#, but then my .NET Form gets confined into the Win32App and that's not what I want.

  • Spring/Eclipse 'referenced bean not found' warning when using <import>?

    - by HDave
    I have just broken up a Spring bean configuration file into smaller external files and have used the the "import" directive to include them in my Spring Test application context XML file. But whenever I reference one of the beans from the imported files I get a warning within Eclipse/STS/Spring XML editor complaining that "referenced bean 'foo' not found" Is this is a bug or is it me? It's really annoying because I don't want to disable the warning, yet at my company we try to eliminate all warnings.

  • Rails - good tool to create a scheduled background process which will regularly retrieve messages fr

    - by adam
    Background Job gets mentioned a lot but all the tutorials I've seen seem to indicate that its for queuing jobs which are created by some external event such as a user clicking "Send mail". But what about when you have code that needs to scheduled to run every 30 seconds to listen for new messages from twitter? Normally rake is recommended for set in stone schedules but it inst so efficient for frequent jobs as it has to to load the entire rails app each time. Can anyone recommend anything for this situation?

  • Weird javascript problem...

    - by Silvio Iannone
    Hi there, i'm building a page that is dinamically loaded with ajax. This is what the '$.get' jQuery function calls (this is located on an external HTML page): <script type="text/javascript"> $(function() { $('button').sb_animateButton(); $('input').sb_animateInput(); $('#settings_security_error').hide(); }); function check_passwords(password, password_confirm) { $('#settings_security_error').show(); alert('I\'m in funcion!'); // This works... if(password.length < 4) // ... this doesn't { $('#settings_security_error').innerHTML = 'Password too short'; } else { password = hex_md5(password); password_confirm = hex_md5(password_confirm); $.get('/engine/ajax/check_password.php?password=' + password + '$password_confirm=' + password_confirm, {language: "php", version: 5}, function(result) { $('#settings_security_error').innerHTML = result; }, 'html'); } } </script> <div class="title">Security</div> <table class="sub_container"> <tr> <td><label>Old password</label></td> <td class="td_input"><input type="password" name="old_password"/></td> </tr> <tr> <td><label>New password</label></td> <td class="td_input"><input type="password" name="new_password" id="settings_security_new_password" onkeyup="check_passwords(this.value, getElementById('settings_security_password_confirm').value)"/></td> </tr> <tr> <td><label>Confirm password</label></td> <td class="td_input"><input type="password" name="new_password_confirm" id="settings_security_password_confirm" onkeyup="check_passwords(getElementById('settings_security_new_password').value, this.value)"/></td> </tr> <tr> <td class="td_error" id="settings_security_error"></td> </tr> </table> And this is where the external HTML is placed...: <div id="settings_appearance"> </div> ... from this javascript snippet: function get_page_content(page, target_id) { $.get('engine/ajax/get_page_content.php?page=' + page, null, function(result) { $("#"+target_id).html(result); // Or whatever you need to insert the result }, 'html'); } Well... the problem is that the javascript in the first snippet is executed when it's loaded by the $.get function, but i still can't understand the reason why when i type into the input boxes nothing happen. It should write the output of the javascript function check_passwords(password, password_confirm) in <td class="td_error" id="settings_security_error"></td>. Thanks for helping. Silvio

  • GCC how to block system calls within a program?

    - by CMPITG
    Does anyone tell me how to block system calls within a program, please? I am building a system which takes a piece of C source code, compiles it with gcc and runs it. For security reasons, I need to prevent the compiled program from calling system calls. Is there any way to do it, from the source code level (e.g. stripping the header files of gcc, detecting malicious external calls, ...) to the executable level?

  • ANTLR, Dynamic variables

    - by JTS
    Hello, I have an ANTLR grammar that can parse and evaluate simple expressions like 1+2*4, etc. What I would like to do is to evaluate expressions like 2+$a-$b/4 where the $ variables are dynamic variables, that come from an external source and are continuously updated. Is there any design pattern on how to do this using ANTLR, best practices, etc? Shall I "substring" the $a with the updated value ($a - 4.34) A nicer way to do this? Thx

  • Meassure website

    - by s0mmer
    Hi, I was wondering if it is possible to install or use any online service to measure your website's performance? I've seen many just checking the download speed of images, external files etc. But is it possible to meassure how long asp/php code takes to execute? I have a site running a bit slowly, and it would be very nice with some app/service guiding where to optimize.

  • Run SQL Queries on DataTables, or similar, in .Net, without an RDBMS

    - by FastAl
    I'd like to have a dataset or datatables, and be able to run SQL statements on them, without using any external RDBMS. For Example, to take take 2 datatables in a dataset and just join them outright with a SQL statement and Where clause, the result being a new datatable? For example if I have 2 datatables, named People and Addresses in a dataset (that I built using code, not getting from a database .. pardon the old fashioned Join syntax): dim dtJoined as DataTable = MyDataSet.RunSQLQuery ("Select * from People, Orders Where People.PersonID=Orders.OrdereID") Thanks

  • Is there any way to run "dir" directly?

    - by Mason Wheeler
    In my answer to this question, where the asker needed a fast way to get a directory listing of a folder on a network drive, I suggested using the DOS "dir" command. Unfortunately, it's a command, not a program, so you can't execute it with CreateProcess and so I had to put it in a batch file. I don't really like that solution. It feels like a hack to me. Does anyone know a way to run dir from Delphi instead of from an external batch file?
