• Sum of a PHP Array

  - by user1879415

  The following code displays the ordered products individual weight: $weightsql = 'select op.products_name, op.products_quantity , p.products_weight from ' . TABLE_ORDERS_PRODUCTS . ' op left join ' . TABLE_PRODUCTS . ' p on op.products_id = p.products_id where op.products_id = '.$pro['products_id']; $weightq = tep_db_query( $weightsql ); while ($weight = tep_db_fetch_array( $weightq )){ if($category_parent_id != 0)$list_items[] = $weight['products_weight'].'&nbsp;&nbsp;&nbsp;'; } This shows the wieght for each of the products ordered. What I am stuck on is instead of showing seperate weights, I need to show a total weight. For example, if the product was ordered three times, and it weighs 7kg, the code at the moment is showing: Product 7.00 7.00 7.00 How would I make it show the total weight, 21kg?

  There is a linker error in my SW. I am using the following structure based on h, hpp, cpp files. Some classes are templatized, some not, some have function templates. Declaration: test.h #ifndef TEST_H #define TEST_H class Test { public: template <typename T> void foo1(); void foo2 () }; #include "test.hpp" #endif Definition: test.hpp #ifndef TEST_HPP #define TEST_HPP template <typename T> void Test::foo1() {} inline void Test::foo2() {} //or in cpp file #endif CPP file: test.cpp #include "test.h" void Test::foo2() {} //or in hpp file as inline I have the following problem.

• How to copy a text array to a series of cells in Excel

  - by aSystemOverload

  I am dynamically creating a report, where I create a worksheet, bring in the records afresh. How can I easily type the field names and copy them to the cells. Without doing one cell per line, there are ~20 columns. I tried: dim fieldNames as variant fieldNames = ("'DS Date', 'A', 'B', 'A','S ASD', 'S','D S','D S', 'S','D S', 'SD', 'S','D'") Sheets("DATA").Range("C14:W14").Value = Application.WorksheetFunction.Transpose(fieldNames) But it just posts the whole thing in each cell? Any ideas?

• Adding to a bit array

  - by Martin

  In my program, I am using BitArrays to represent 160 bit numbers. I want to be able to add, subtract, increment and decrement these numbers, what is the algorithm for doing this? At the moment I'm not interested in multiplication and division, but I might be in the future so bonus points for that. I'm implementing in C#, but pseudocode is fine if you're not familiar with the language

• char array split ip with strtok

  - by user1480139

  I'm trying to split a IP address like 127.0.0.1 from a file: using following C code: pch2 = strtok (ip,"."); printf("\npart 1 ip: %s",pch2); pch2 = strtok (NULL,"."); printf("\npart 2 ip: %s",pch2); And IP is a char ip[500], that containt an ip. When printing it prints 127 as part 1 but as part 2 it prints NULL? Can someone help me? EDIT: Whole function: FILE *file = fopen ("host.txt", "r"); char * pch; char * pch2; char ip[BUFFSIZE]; IPPart result; if (file != NULL) { char line [BUFFSIZE]; while(fgets(line,sizeof line,file) != NULL) { if(line[0] != '#') { //fputs(line,stdout); pch = strtok (line," "); printf ("%s\n",pch); strncpy(ip, pch, sizeof(pch)-1); ip[sizeof(pch)-1] = '\0'; //pch = strtok (line, " "); pch = strtok (NULL," "); printf("%s",pch); pch2 = strtok (ip,"."); printf("\nDeel 1 ip: %s",pch2); pch2 = strtok (NULL,"."); printf("\nDeel 2 ip: %s",pch2); //if(strcmp(pch,url) == 0) //{ // result.part1 = //} } } fclose(file); }

• Is the following array really multidimensional?

  - by flockofcode

  Book I’ learning from claims that intArray has two dimensions. But since calling intArray.GetLength(1) will result in an IndexoutOfRange exception, couldn’t we claim that unlike rectangular arrays, intArray isn’t really multidimensional and thus has only one dimension? int[][] intArray=new int[3][]; thank you

• Dynamically created jagged "rectangle" array

  - by gagar1n

  In my project I have a lot of code like this: int[][] a = new int[firstDimension][]; for (int i=0; i<firstDimension; i++) { a[i] = new int[secondDimension]; } Types of elements are different. Is there any way of writing a method like createArray(typeof(int), firstDimension, secondDimension); and getting new int[firstDimension][secondDimension]? Once again, type of elements is known only at runtime.

• replace commas with spaces from json array

  - by Alex

  I have a looping function creating: <li id="id1" name="Tag1,Tag2,Tag3"> <li id="id2" name="Tag1,Tag2,Tag3"> $.each(data.posts, function(i, post){ $('<li >', {id: this.id , name: post.tags}) }); How do I replace the commas between the tags with spaces. Also is there a way I can send the tags to a "class" attribute instead of "name". It seems to not work in Safari.

• PHP Count the lenght of each value in a array/string (tags)

  - by 2by

  Users writing an article have the option to write some tags, tags are written like this: tag1, tag2, tag3 So tags are stored like: $tags = "tag1, tag2, tag3"; I want to make sure, every tag has a minimum of 3 characters, so i need to validate the tags. I have tried this: $tagsstring = explode(",", $tags); $tagslength = array_map('strlen', $tagsstring); if (min($tagslength) < 3) { echo "Error... Each tag has to be at least 3 characters."; } It seems to work, sometimes... But of you write: tag1, df It wont give an error. Any suggestions?

• Array Indexing Properties of A Class

  - by Chris

  I have a class that has several properties: class Person { string Name; int Age; DateTime BirthDate; } Then I have a sort of wrapper class with a List<Person>. Within this wrapper class I want to be able to do something like Wrapper["Name"] that returns a new List<string> using .Select(x=>x.Name). How do I create a wrapper class around an IEnumerable that supports mapping a string to the Property name? Something like the pseudo code below, but obviously it doesn't work. I'm 99.9% sure the solution will have to use Reflection and thats fine. class Wrapper { List<Person> PersonList; List<dynamic> this[string Column] { return PersonList.Select(x => x.[Column]).ToList(); } } This may not seem like a good design, but its a fix to eventually enable the correct design from .NET 2.0 days. As I have it right now, the data is stored in Columns, so there is actually a List of Lists within my class right now. Using the above example there would be three ILists (with a string Title) Name, Age, and Birthdate. Everything is currently predicated on addressing the columns by their "string" name. I'm trying to convert the data structure to row based with an IEnumberable interface to allow Linq eventually while still maintaining the functionality of my current code. Is converting the code to a Row based IEnumberable a good idea?

• how to use static function in header and compare with float array

  - by ed k

  I wrote this function: static bool colorIsEmpty(const Color col) { return (col[0] == 0 && col[1] == 0 && col[2] == 0 ); } where Color is simply a float[3]; the function doesn't work if col[3] are all 0; but this works: if(col[0] == col[1] == col[2] == 0) { //gets called } however gcc gives me warning: cColorTest.c:212:5: warning: suggest parentheses around comparison in operand of ‘==’ [-Wparentheses] so it would be nice if that function works,why it doesn't work?

• Flexible array member in C-structure

  - by Arpan

  Quoting from the C-std section 6.7.2.1, struct s { int n; double d[]; }; This is a valid structure declaration. I am looking for some practical use of this kind of syntax. To be precise, how is this construct any more or less powerful than keeping a double* as the 2nd element? Or is this another case of 'you-can-do-it-in-multiple-ways'? Arpan

• Update int array based on parent

  - by Pickels

  I have the following int[] in my database: '{0}' '{0,0}' '{0,0,0}' '{0,0,0,0}' This column is used to sort my tree data. Now when a parent updates it's order the children should also update. For example if the second record updates it's order to 1 it should result in the following. '{0}' '{0,1}' '{0,1,0}' '{0,1,0,0}' So I was wondering what the query would be to update record 3 and 4. In case it's not clear what I am asking leave a comment I can add additional information. Screenshot of my actual data:
