  • fill a buffer successively

    - by mkind
    i intend to fill a char-pointer array successively in a for-loop. the content to fill in is a integer so i need to cast. but i didn't get the result i want to.. for (i=0;i<max0;i++){ sprintf(buf, "%d", content[i]); } sprintf replaces the hole buf, but i want to append. for (i=0;i<max0;i++){ buf[i]=(char) contint[i] } but this isn't working too. it seems to me, i get ascii-code of the content[i].

  • MultiThreading question

    - by TiGer
    Hi, I am developing on Android but the question might be just as valid on any other Java platform. I have developed a multi-threaded app. Lets say I have a first class that needs to do a time-intensive task, thus this work is done in another Thread. When it's done that same Thread will return the time-intensive task result to another (3rd) class. This last class will do something and return it's result to the first-starting class. I have noticed though that the first class will be waiting the whole time, maybe because this is some kind of loop ? Also I'd like the Thread-class to stop itself, as in when it has passed it's result to the third class it should simply stop. The third class has to do it's work without being "incapsulated" in the second class (the Thread one). Anyone knows how to accomplish this ? right now the experience is that the first one seems to be waiting (hanging) till the second and the third one are done :(

  • C++11 initialize array with uniform value in constexpr function

    - by marack
    I have a class template which builds a simple array based on the template parameters as one of its members. I need to be able to initialize every element in the array to a single value in one of the constructors. Unfortunately this constructor must be constexpr. The relevant part boils down to: template <typename T, size_t N> class foo { T data[N]; constexpr foo(T val) { // initialize data with N copies of val } }; Using std::fill or a loop is incompatible with the constexpr requirement. Initializing with : data{val} only sets the first element of the array and zero-initializes the remainder. How can this be achieved? I feel like there should be a solution with variadic templates and tuples etc...

  • C++ Regarding cin.ignore()

    - by user1578897
    i would hope someone can modify my code as its so buggy. sometime its work, sometime it dont.. so let me explain more.. Text file data is as below Line3D, [70, -120, -3], [-29, 1, 268] Line3D, [25, -69, -33], [-2, -41, 58] To read the above line.. i use the following char buffer[30]; cout << "Please enter filename: "; cin.ignore(); getline(cin,filename); readFile.open(filename.c_str()); //if successfully open if(readFile.is_open()) { //record counter set to 0 numberOfRecords = 0; while(readFile.good()) { //input stream get line by line readFile.getline(buffer,20,','); if(strstr(buffer,"Point3D")) { Point3D point3d_tmp; readFile>>point3d_tmp; // and so on... Then i did a overload on the ifstream for Line3d ifstream& operator>>(ifstream &input,Line3D &line3d) { int x1,y1,z1,x2,y2,z2; //get x1 input.ignore(2); input>>x1; //get y1 input.ignore(); input>>y1; //get z1 input.ignore(); input>>z1; //get x2 input.ignore(4); input>>x2; //get y2 input.ignore(); input>>y2; //get z2 input.ignore(); input>>z2; input.ignore(2); Point3D pt1(x1,y1,z1); Point3D pt2(x2,y2,z2); line3d.setPt1(pt1); line3d.setPt2(pt2); line3d.setLength(); } But the issue is the record work sometime and sometime it dont.. what i mean is if at this point //i add a cout cout << x1 << y1 << z1; cout << x2 << y2 << z2; //its works! Point3D pt1(x1,y1,z1); Point3D pt2(x2,y2,z2); line3d.setPt1(pt1); line3d.setPt2(pt2); line3d.setLength(); but if i take away the cout it dont work. how do i change my cin.ignore() so the data can be handle properly , consider number range is -999 to 999

  • How do I use link_to_remote to pass then render a partial in rails?

    - by Angela
    I want to create several link_to_remote links that are campaign names: <% @campaigns.each do |campaign| %> <!--link_to_remote(name, options = {}, html_options = nil)--> <%= link_to_remote(campaign, :update => "campaign_todo", :url => %> <% end %> I want the output to update on the page to render a partial, which runs a loop through the values associated with the campaign. The API docs says this will render a partial, but I'm not clear where the name of the :partial template is passed in, either here or in the controller Thanks.

  • Is it bad practice to initialize a variable to a dummy value?

    - by froadie
    This question is a result of the answers to this question that I just asked. It was claimed that this code is "ugly" because it initializes a variable to a value that will never be read: String tempName = null; try{ tempName = buildFileName(); } catch(Exception e){ ... System.exit(1); } FILE_NAME = tempName; Is this indeed bad practice? Should one avoid initializing variables to dummy values that will never actually be used? (EDIT - And what about initializing a String variable to "" before a loop that will concatenate values to the String...? Or is this in a separate category? e.g. String whatever = ""; for(String str : someCollection){ whatever += str; } )

  • Scala updating/creating value in a hashmap

    - by user1672739
    I don't understand this with Scala hasmaps: How do I create a value or update one if it does not exist? I am tryng to count the number of characters in a list of Strings. I've tried this code but it doesn't work : def times(chars: List[Char]): List[(Char, Int)] = { val map = new HashMap[Char, Int]() chars.foreach( (c : Char) => { map.update(c, map.get(c) + 1) }) } I understand the returning type isn't correct. But is my foreach loop wrong? Is there a prettier way to write it?

  • Accessing Variables in Javascript using .length

    - by CoV
    Hey all, I'm pretty new to Javascript, so forgive me if this is a simple question. I'm trying to access the length of a set of checkboxes in a form using Javascript. However, I need to be able to change the "name" field of the checkboxes to check several different sets of them. Right now, my sample code looks like: var set = "set" + x; totalLength = optionBoxes.set.length; The variable x is being incremented by a for loop that wraps the whole thing and the name of the checkbox sets that I'm trying to access are set0, set1, set2, etc. Thanks. Edit: small typo fixes

  • LINQ Query based on user preferences

    - by Chris Phelps
    How can I do this better (so it actually works : ) I have a LINQ Query that includes an order by that is based on a user preference. The user can decide if they would like the results ordered asc or desc. If fuserclass.SortOrder = "Ascending" Then Dim mydat = (From c In dc.ITRS Order By c.Date Ascending Select c) Else Dim mydat = (From c In dc.ITRS Order By c.Date Descending Select c) End If For each mydata in mydat ***<<<error "mydat is not declared"*** I know I could put my For Each loop inside the If and Else, but that seems silly to have the same code twice. I know you know of a better way : )

  • Mysterious c debugging problem when trying to utilize printfs

    - by O_O
    Ok, folks. I've never encountered this before and it boggles the mind and is illogical. I have a somewhat complex loop and I want to try and see if everything is working by putting some printf statements. I look the intermediate products using printf and verify that the answer is ok. Then, when I comment out the printf to the intermediate products, the answer is WRONG. Has anyone ever encountered this? This is driving me insane and I don't see how the printfs could change an answer.... X_x If it helps, I am using a c/c++ compiler for a DSP. Thanks for any advice.. Here is a snippet... printf("splitBackground = %d, numWindowPoints = %d\n", splitBackground, numWindowPoints); splitBackground = splitBackground/numWindowPoints; printf("%d ", splitBackground); This is good but when I comment out the first line of code, it turns out to be hugely incorrect. :(

  • "tail -f" alternate which doesn't scroll the terminal window

    - by Jagtesh Chadha
    I want to check a file at continuous intervals for contents which keep changing. "tail -f" doesn't suffice as the file doesn't grow in size. I could use a simple while loop in bash to the same effect: while [ 1 ]; do cat /proc/acpi/battery/BAT1/state ; sleep 10; done It works, although it has the unwanted effect of scrolling my terminal window. So now I'm wondering, is there a linux/shell command that would display the output of this file without scrolling the terminal?

  • Querying a smalldatetime's date and time seperately in SQL server?

    - by Kylee
    Imagine a table that has two fields, a smalltimedate and an int and about 1000 rows of data. What I'm attempting to do in query is to find the average of the INT field for rows between 3/3/2010 - 3/13/2010 and only if the entry is between 6:00am - 11:00pm. I tried between '2010-03-03 06:00 AND 2010-03-13 23:00' However that only restricts that very beginning and end times. I could do this with a loop but I'm going to need to have the same query run over much larger date ranges and this will quickly eat server resources. Is there a way to query date and time seperately?

  • PHP Array issue - not looping through foreach...

    - by Homer_J
    Ok, Here is the code: function fetch_questions($page) { global $link; $proc = mysqli_prepare($link, "SELECT * FROM tquestions_cwh WHERE page = ?"); mysqli_stmt_bind_param($proc, "i", $page); mysqli_stmt_execute($proc); $rows = array(); stmt_bind_assoc($proc, $rowq); // loop through all result rows while ($proc->fetch()) { // print_r($rowq); $rows[]=$rowq; } mysqli_stmt_close($proc); mysqli_clean_connection($link); return($rows); } I then add this to a php variable, like so: $qs = fetch_questions($page); I then loop through is, like so: foreach($qs as $value){ echo "<tr>".$value['qnum']." is the questions number and the question text is ".$value['qtext'].". The page and q values are ".$value['page']." and ".$value['questions']." respectively.</tr>"; The output, however is this: 8 is the questions number and the question text is I know how what I do fits into my team's objectives. The page and q values are 1 and q8 respectively.8 is the questions number and the question text is I know how what I do fits into my team's objectives. The page and q values are 1 and q8 respectively.8 is the questions number and the question text is I know how what I do fits into my team's objectives. The page and q values are 1 and q8 respectively.8 is the questions number and the question text is I know how what I do fits into my team's objectives. The page and q values are 1 and q8 respectively.8 is the questions number and the question text is I know how what I do fits into my team's objectives. The page and q values are 1 and q8 respectively.8 is the questions number and the question text is I know how what I do fits into my team's objectives. The page and q values are 1 and q8 respectively.8 is the questions number and the question text is I know how what I do fits into my team's objectives. The page and q values are 1 and q8 respectively.8 is the questions number and the question text is I know how what I do fits into my team's objectives. The page and q values are 1 and q8 respectively. Which is not what I want, for information purposes, the array using the print function looks like this: Array ( [0] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [1] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [2] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [3] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [4] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [5] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [6] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [7] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) ) Clearly it's not looping through and displaying each row as it should...any advice? Homer.

  • Disabled Select drop down checking through PHP

    - by user541597
    I have a couple of drop down boxes I access through POST with PHP. When the boxes are disabled and not equal to zero I have the program do something. However when they are disabled I do not want them to do anything. The way I check if the boxes are active is by using an if statement if ($_POST['box'] != "blank"){ //do something } So basically I check if the box is not in the default blank position run the if statement. However when it is disabled I am not sure how to check or what kind of value it returns if any. What can I add to the if statement so it will not go into the loop when the boxes are disabled? I tried: if ($_POST['box'] != "blank" || $_POST['box'] != ""){ //do something } But that did not work. Any ideas?

  • stringindexoutofbounds with currency converter java program

    - by user1795926
    I am have trouble with a summary not showing up. I am supposed to modify a previous Java assignment by by adding an array of objects. Within the loop, instantiate each individual object. Make sure the user cannot keep adding another Foreign conversion beyond your array size. After the user selects quit from the menu, prompt if the user want to display a summary report. If they select ‘Y’ then, using your array of objects, display the following report: Item Conversion Dollars Amount 1 Japanese Yen 100.00 32,000.00 2 Mexican Peso 400.00 56,000.00 3 Canadian Dollar 100.00 156.00 etc. Number of Conversions = 3 There are no errors when I compile..but when I run the program it is fine until I hit 0 to end the conversion and have it ask if i want to see a summary. This error displays: Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 0 at java.lang.String.charAt(String.java:658) at Lab8.main(Lab8.java:43) my code: import java.util.Scanner; import java.text.DecimalFormat; public class Lab8 { public static void main(String[] args) { final int Max = 10; String a; char summary; int c = 0; Foreign[] Exchange = new Foreign[Max]; Scanner Keyboard = new Scanner(System.in); Foreign.opening(); do { Exchange[c] = new Foreign(); Exchange[c].getchoice(); Exchange[c].dollars(); Exchange[c].amount(); Exchange[c].vertical(); System.out.println("\n" + Exchange[c]); c++; System.out.println("\n" + "Please select 1 through 4, or 0 to quit" + >"\n"); c= Keyboard.nextInt(); } while (c != 0); System.out.print("\nWould you like a summary of your conversions? (Y/N): "); a = Keyboard.nextLine(); summary = a.charAt(0); summary = Character.toUpperCase(summary); if (summary == 'Y') { System.out.println("\nCountry\t\tRate\t\tDollars\t\tAmount"); System.out.println("========\t\t=======\t\t=======\t\t========="); for (int i=0; i < Exchange.length; i++) System.out.println(Exchange[i]); Foreign.counter(); } } } I looked at line 43 and its this line: summary = a.charAt(0); But I am not sure what's wrong with it, can anyone point it out? Thank you.

  • Multiple HTTP request - Rails

    - by bradleyg
    My application checks a number of domains to see if they are valid (approx 100). I have the following code to check a single domain: def self.test_url uri, limit = 10 if limit == 0 return get_error_messages("001") end begin url = URI.parse(uri) response = Net::HTTP.start(url.host, url.port).request_head('/') rescue SocketError => e return get_error_messages("002") end case response when Net::HTTPRedirection then test_url(response['location'], limit - 1) else return get_error_messages(response.code) end end The code checks for the response code while taking into account redirects. This works fine. The only problem I have is when I put this in a loop I want it to run in parallel. So I don't have to wait for domain 1 to respond before I can request domain 2. I have managed this in PHP using curl_multi to run the requests in parallel. Is there a similar thing I can do in Rails?

  • Core Data: Detecting the type and casting it

    - by Tim Sullivan
    I have set up a Core Data model that includes an entity, Item with a 1-M relationship with the abstract entity Place, so that an item has many places. There are several entities with the parent set to Place. I want to set up several UI elements depending on the descendent place types. I have a loop that looks something like this: for (Place *place in item.places) { } ... but I'm not sure how to detect what type the place is, and how to cast it to the proper type so that I can access its properties. Thanks for any help!

  • Does a CPU assigns a value atomically to memory?

    - by Poni
    Hi! A quick question I've been wondering about for some time; Does the CPU assign values atomically, or, is it bit by bit (say for example a 32bit integer). If it's bit by bit, could another thread accessing this exact location get a "part" of the to-be-assigned value? Think of this: I have two threads and one shared "unsigned int" variable (call it "g_uiVal"). Both threads loop. On is printing "g_uiVal" with printf("%u\n", g_uiVal). The second just increase this number. Will the printing thread ever print something that is totally not or part of "g_uiVal"'s value? In code: unsigned int g_uiVal; void thread_writer() { g_uiVal++; } void thread_reader() { while(1) printf("%u\n", g_uiVal); }

  • PhotobucketNet photo upload

    I have a problem with PhotobucketNet user login(I need user to login so I can upload a picture from HDD to his Photobucket account). Photobucket photobucket = new Photobucket("myapikey", "myapisecret"); photobucket.LaunchUserLogin(); // the problem happens here photobucket.RequestUserToken(); If I call RequestUserToken() it will happen immediately, so I'll get a crash cause user didn't logged in, and there is no event that's been raised after user logs in. Is there some variable(bool or something else) that I can check to see if user logged in - maybe to put it in a loop with timer? Also is their a way to know if user canceled logging in? I know that timer isn't a good solution, so if anyone has anything better as an idea, I'm open for any suggestions...

  • Delays in ActionScript (Flash)? Alternatives to setInterval

    - by yar
    While setInterval is handy, it's kind of limiting. Every time I want to add a Tween I have to add a new method. I do not want to alter the structure of my code just to add in some delays. Isn't there any way to say this without making methods for A and B? // do A // wait N seconds // do B I don't want to use a while loop with Dates because I think it will be blocking. Isn't there anything like Thread.sleep in ActionScript?
