  • Shell Script - print selected columns

    - by teepusink
    Hi, I have a txt file with columns separated by tabs and based on that file, I want to create a new file that only contains information from some of the columns. This is what I have now awk '{ print $1, $5 }' filename newfilename That works except that when column 5 contains spaces e.g 123 Street, only 123 shows up and the street is considered as another column. How can I achieve what I'm trying to do? Thanks, Tee

  • C preprocessor: using #if inside #define?

    - by Wxy
    I want to write a macro that spits out code based on the boolean value of its parameter. So say DEF_CONST(true) should be expanded into "const", and DEF_CONST(false) should be expanded into nothing. Clearly the following doesn't work because we can't use another preprocessor inside #defines: #define DEF_CONST(b_const) \ #if (b_const) \ const \ #endif Any idea about how to do it?

  • SQL-How to retrieve the correct data using php

    - by Programatt
    I am new to SQL so please excuse my question if it is simple. I have a database with a few tables. 1 is a users table, the others are application tables that contain the users preferences for receiving notifications about that application based on the country they are interested in. What I want to do, is retrieve the e-mail address of all users that have an interest in that country. I am struggling to think about how to do this. I currently have the following query constructed, and the code to populate the values function check($string) { if (isset($_POST[$string])) { $print = implode(', ', $_POST[$string]); //Converts an array into a single string $imanageSQLArr = Array(); if (substr_count($print,'Benelux') > 0) { $imanageSQLArr[0] = "checked"; } else { $imanageSQLArr[0] = "off"; } if (substr_count($print, 'France') > 0) { $imanageSQLArr[1] = "checked"; } else { $imanageSQLArr[1] = "off"; } if (substr_count($print, 'Germany') > 0) { $imanageSQLArr[2] = "checked"; } else { $imanageSQLArr[2] = "off"; } if (substr_count($print, 'Italy') > 0) { $imanageSQLArr[3] = "checked"; } else { $imanageSQLArr[3] = "off"; } if (substr_count($print, 'Netherlands') > 0) { $imanageSQLArr[4] = "checked"; } else { $imanageSQLArr[4] = "off"; } if (substr_count($print, 'Portugal') > 0) { $imanageSQLArr[5] = "checked"; } else { $imanageSQLArr[5] = "off"; } if (substr_count($print, 'Spain') > 0) { $imanageSQLArr[6] = "checked"; } else { $imanageSQLArr[6] = "off"; } if (substr_count($print, 'Sweden') > 0) { $imanageSQLArr[7] = "checked"; } else { $imanageSQLArr[7] = "off"; } if (substr_count($print, 'Switzerland') > 0) { $imanageSQLArr[8] = "checked"; } else { $imanageSQLArr[8] = "off"; } if (substr_count($print, 'UK') > 0) { $imanageSQLArr[9] = "checked"; } else { $imanageSQLArr[9] = "off"; } and the query $tocheck = $db->prepare( "SELECT users.email FROM users,app WHERE users.id=app.userid AND BENELUX=:BENELUX AND FRANCE=:FRANCE AND GERMANY=:GERMANY AND ITALY=:ITALY AND NETHERLANDS=:NETHERLANDS AND PORTUGAL=:PORTUGAL AND SPAIN=:SPAIN AND SWEDEN=:SWEDEN AND SWITZERLAND=:SWITZERLAND AND UK=:UK"); $tocheck->execute($country); $row = $tocheck->fetchAll(); This does retrieve data, but only people who's preferences match EXACTLY what is put (so what they haven't selected is taken into account as much as what they have). Any help would be greatly appreciated.

  • Why is Serializable Attribute required for an object to be serialized

    - by Keivan
    Based on my understanding SerializableAttribute provides no compile time checks, as its all done at runtime, then why is it required for classes to be marked as serializable? Couldn't sterilizer just try to serialize an object and just fail? isn't it what it does right-now when something is marked, it tries and fails. wouldn't it be better if you had to mark things as unserializable rather than serializable? that way you wouldn't have the problem of libraries not marking things as serializable?

    - by Leonel
    Hi, We have an application running on CLDC 1.1/MIDP 2.1, based on Midlets and lcdui. Is it possible to run the same application on CDC 1.1 with the PBP profile ? If so, where should I even start ? I'm using Sun WTK 3.0. With CLDC, the starting point is a JAD file, which indicates the name of the main midlet class. What is the starting point of an application on CDC ?

  • Assigning IDs to instances of a class (Pythonic)

    - by mellort
    I want to have each instance of some class have a unique integer identifier based on the order that I create them, starting with (say) 0. In Java, I could do this with a static class variable. I know I can emulate the same sort of behavior with Python, but what would be the most 'Pythonic' way to do this? Thanks

  • Linking to a section of a site that is hidden by a hide/show JavaScript function

    - by hollyb
    I am using a bit of JavaScript to show/hide sections of a site when a tab is clicked. I'm trying to figure out if there is a way I can link back to the page and have a certain tab open based on that link. Here is the JS: var ids=new Array('section1','section2','section3','section4'); function switchid(id, el){ hideallids(); showdiv(id); var li = el.parentNode.parentNode.childNodes[0]; while (li) { if (!li.tagName || li.tagName.toLowerCase() != "li") li = li.nextSibling; // skip the text node if (li) { li.className = ""; li = li.nextSibling; } } el.parentNode.className = "active"; } function hideallids(){ //loop through the array and hide each element by id for (var i=0;i<ids.length;i++){ hidediv(ids[i]); } } function hidediv(id) { //safe function to hide an element with a specified id document.getElementById(id).style.display = 'none'; } function showdiv(id) { //safe function to show an element with a specified id document.getElementById(id).style.display = 'block'; } And the HTML <ul> <li class="active"><a onclick="switchid('section1', this);return false;">One</a></li> <li><a onclick="switchid('section2', this);return false;">Two</a></li> <li><a onclick="switchid('section3', this);return false;">Three</a></li> <li><a onclick="switchid('section4', this);return false;">Four</a></li> </ul> <div id="section1" style="display:block;"> <div id="section2" style="display:none;"> <div id="section3" style="display:none;"> <div id="section4" style="display:none;"> I haven't been able to come up with a way to link back to a specific section. Is it even possible with this method? Thanks!

  • How do I create and read non-global variables that aren't destroyed at end of function?

    - by Paul Reilly
    I am attempting to code some plugins to use with MIDI sequencers but have hit a stumbling block. I can't use global-scope variables to store information because multiple instances of the .dll can exist which share memory. How do I create a class (for re-usability purposes in other plugins) containing 2 dimensional array and other variables the content of which is to be shared between functions? If that is possible, how would I read and write the data from the function in the framework where I do the processing?

  • How to pick random (small) data samples using Map/Reduce?

    - by Andrei Savu
    I want to write a map/reduce job to select a number of random samples from a large dataset based on a row level condition. I want to minimize the number of intermediate keys. Pseudocode: for each row if row matches condition put the row.id in the bucket if the bucket is not already large enough Have you done something like this? Is there any well known algorithm? A sample containing sequential rows is also good enough. Thanks.

    - by Vishal Seth
    Is there a plug-in like the java applet @ SQLinForm.com for MS SQL Server Management Studio 2008?

  • Seg Fault with malloc'd pointers

    - by anon
    I'm making a thread class to use as a wrapper for pthreads. I have a Queue class to use as a queue, but I'm having trouble with it. It seems to allocate and fill the queue struct fine, but when I try to get the data from it, it Seg. faults. http://pastebin.com/Bquqzxt0 (the printf's are for debugging, both throw seg faults) edit: the queue is stored in a dynamically allocated "struct queueset" array as a pointer to the data and an index for the data
