  • C#: reading in a text file more 'intelligently'

    - by DarthSheldon
    I have a text file which contains a list of alphabetically organized variables with their variable numbers next to them formatted something like follows: aabcdef 208 abcdefghijk 1191 bcdefga 7 cdefgab 12 defgab 100 efgabcd 999 fgabc 86 gabcdef 9 h 11 ijk 80 ... ... I would like to read each text as a string and keep it's designated id# something like read "aabcdef" and store it into an array at spot 208. The 2 issues I'm running into are: I've never read from file in C#, is there a way to read, say from start of line to whitespace as a string? and then the next string as an int until the end of line? given the nature and size of these files I do not know the highest ID value of each file (not all numbers are used so some files could house a number like 3000, but only actually list 200 variables) So how could I make a flexible way to store these variables when I don't know how big the array/list/stack/etc.. would need to be.

  • Removing “duplicate objects” with same attributes using Array.map

    - by keruilin
    As you can see in the current code below, I am finding the duplicate based on the attribute recordable_id. What I need to do is find the duplicate based on four matching attributes: user_id, recordable_type, hero_type, recordable_id. How must I modify the code? heroes = User.heroes for hero in heroes hero_statuses = hero.hero_statuses seen = [] hero_statuses.sort! {|a,b| a.created_at <=> b.created_at } # sort by created_at hero_statuses.each do |hero_status| if seen.map(&:recordable_id).include? hero_status.recordable_id # check if the id has been seen already hero_status.revoke else seen << hero_status # if not, add it to the seen array end end end

  • preg_replace replacing with array

    - by Scott
    What I want to do is replace the "[replace]" in input string with the corresponding vaule in the replace array. The total number of values will change but there will always be the same number in the replace array as in input string. I have tried doing this with preg_replace and preg_replace_callback but I can't get the pattern right for [replace], I also tried using vsprintf but the % in <table width="100%"> was messing it up. All help is greatly appreciated! Replace Array: $array = array('value 1','value 2','value 3'); Input String $string = ' <table width="100%"> <tr> <td>Name:</td> <td>[replace]</td> </tr> <tr> <td>Date:</td> <td>[replace]</td> </tr> <tr> <td>Info:</td> <td>[replace]</td> </tr> </table> '; Desired Result <table width="100%"> <tr> <td>Name:</td> <td>value 1</td> </tr> <tr> <td>Date:</td> <td>value 2</td> </tr> <tr> <td>Info:</td> <td>value 3</td> </tr> </table>

  • Prevent initial array from sorting

    - by George
    I have an array where the order of the objects is important for when I finally output the array in a document. However, I'm also sorting the array in a function to find the highest value. The problem is that I after I run the function to find the highest value, I can't get the original sort order of the array back. // html document var data = [75,300,150,500,200]; createGraph(data); // js document function createGraph(data) { var maxRange = getDataRange(data); // simpleEncode() = google encoding function for graph var dataSet = simpleEncode(data,maxRange); } function getDataRange(dataArray) { var num = dataArray.sort(sortNumber); return num[0]; } I've also tried setting data to dataA and dataB and using dataB in the getDataRange function and dataA in the simpleEncode function. Either way, data always end up being sorted from highest to lowest.

  • PHP: Display comma after each element except the last. Using 'for' statement and no 'implode/explode

    - by Jonathan
    hi, so I have this simple for loop to echo an array: for ($i = 0; $i < count($director); $i++) { echo '<a href="person.php?id='.$director[$i]["id"].'">'.$director[$i]["name"].'</a>'; } The problem here is that when more than one element is in the array then I get everything echoed without any space between. I want to separate each element with a comma except the last one. I cant use 'implode' so I'm looking for another solution... Anyone?

  • Best way to make sure I get all available options array/loop

    - by jaz872
    OK, here is my problem. I'm looking for the best way to loop through a bunch of options to make sure that I hit all available options. Some detail. I've created a feature that allows a client to build images that are basically other images layered on top of each other. These other images are split up into different groups. They have links on the side of the image that they can click to scroll through all the different images to view them. I'm now making an automated process that is going to run the function that changes the image when a user clicks one of the links. I need to make sure that every possible combo of the different images is hit during this process. So I have an array with the number of options for each group. The current array is [3, 9, 3, 3] My question is what is the best way to loop through this to make sure that all possible options will be shown? I apologize if this seems simple for someone out there, but I'm just having trouble wrapping my head around it. Hopefully if that person is out there, they can give a helping hand :)

  • Easy way to cast an object array into another type in C#

    - by Na7coldwater
    I want to be able to be able to quickly cast an array of objects to a different type, such as String, but the following code doesn't work: String[] a = new String[2]; a[0] = "Hello"; a[1] = "World"; ArrayList b = new ArrayList(a); String[] c = (String[]) b.ToArray(); And I don't want to have to do this: String[] a = new String[2]; a[0] = "Hello"; a[1] = "World"; ArrayList b = new ArrayList(a); Object[] temp = b.ToArray(); Object[] temp = b.ToArray(); String[] c = new String[temp.Length]; for(int i=0;i<temp.Length;i++) { c[i] = (String) temp[i]; } Is there an easy way to do this without using a temporary variable?

  • PHP Undefined index - Occuring when the variable has a value in it

    - by Adam
    I have the following code that is being used to successfully upload images: $fileName = $_FILES['file']['name']; $fileSize = $_FILES['file']['size']; $fileType = $_FILES['file']['type']; $fileTmp = $_FILES['file']['tmp_name']; list($origWidth, $origHeight) = getimagesize($fileTmp); The catch is I'm getting an 'Undefined index' on each line. I have print_r($_FILES) just before this code and each array variable exists and I've echo out varibles like $fileName and can see each has a value. Also I have put this before this code block and it makes no difference: $fileName = $fileSize = $fileType = $fileTmp = ''; Any suggestions how I can ensure these variables are defined? thankyou

  • post__not_in only excluding first post in array

    - by fightstarr20
    I am using two query_posts loops to firstly display a set of posts with a custom field of '2012' and then the second loop to display everything else excluding the posts it returned in the first... <?php if( get_query_var('paged') < 2 ) { ?> <?php query_posts( array( 'post_type' => 'project', 'meta_key' => 'start_date_year', 'meta_value' => '2012' )); $ids = array(); ?> <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?> <p>This is from Loop 1 - <?php the_title(); ?> - <?php the_id(); ?></p> <?php $ids[] = get_the_ID(); ?> <?php endwhile; endif; wp_reset_query(); ?> <?php } ?> <?php $paged = get_query_var( 'paged' ) ? get_query_var( 'paged' ) : 1; query_posts( array( 'post_type' => 'project', 'post__not_in' => $ids, 'orderby' => title, 'order' => ASC, 'paged' => $paged )); ?> <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?> <p>This is from Loop 2 - <?php the_title(); ?> - <?php the_id(); ?></p> <?php endwhile; endif; wp_reset_query(); ?> <?php pagination(); ?> For some reason the 'post__not_in' = $ids is only excluding the first post ID in the array, I have print_r the array and it does contain all of the post IDs I want to exlcude. Anyone any ideas why only one ID is being excluded?

  • Looping through array values using JQuery and show them on separate lines

    - by user3192948
    I'm building a simple shopping cart where visitors can select a few items they want, click on the "Next" button, and see the confirmation list of things they just selected. I would like to have the confirmation list shown on each line for each item selected. HTML selection <div id="c_b"> <input type="checkbox" value="razor brand new razor that everyone loves, price at $.99" checked> <input type="checkbox" value="soap used soap for a nice public shower, good for your homies, price at $.99" checked> <input type="checkbox" value="manpacks ultimate choice, all in 1, price at $99"> </div> <button type='button' id='confirm'>Next</button> HTML confirmation list <div id='confirmation_list' style='display:none;'> <h2>You have selected item 1</h2> <h2>Your have selected item 2 </h2> </div> JS $(function(){ $('#confirm').click(function(){ var val = []; $(':checkbox:checked').each(function(i){ val[i] = $(this).val(); }); }); }); I ultimately want to replace the words 'Your have selected item 2' in h2s with the values selected from each check box. With the code above I'm able to collect the values of each checkbox into an array val, but having difficulty looping through and displaying them. Any advice would be appreciated.
