  • Parse lines of integers in C

    - by Jérôme
    This is a classical problem, but I can not find a simple solution. I have an input file like: 1 3 9 13 23 25 34 36 38 40 52 54 59 2 3 9 14 23 26 34 36 39 40 52 55 59 63 67 76 85 86 90 93 99 108 114 2 4 9 15 23 27 34 36 63 67 76 85 86 90 93 99 108 115 1 25 34 36 38 41 52 54 59 63 67 76 85 86 90 93 98 107 113 2 3 9 16 24 28 2 3 10 14 23 26 34 36 39 41 52 55 59 63 67 76 Lines of different number of integers separated by a space. I would like to parse them in an array, and separate each line with a marker, let say -1. The difficulty is that I must handle integers and line returns. Here my existing code, it loops upon the scanf loop (because scanf can not begin at a given position). #include <stdio.h> #include <stdlib.h> int main(int argc, char **argv) { if (argc != 4) { fprintf(stderr, "Usage: %s <data file> <nb transactions> <nb items>\n", argv[0]); return 1; } FILE * file; file = fopen (argv[1],"r"); if (file==NULL) { fprintf(stderr, "Error: can not open %s\n", argv[1]); fclose(file); return 1; } int nb_trans = atoi(argv[2]); int nb_items = atoi(argv[3]); int *bdd = malloc(sizeof(int) * (nb_trans + nb_items)); char line[1024]; int i = 0; while ( fgets(line, 1024, file) ) { int item; while ( sscanf (line, "%d ", &item )){ printf("%s %d %d\n", line, i, item); bdd[i++] = item; } bdd[i++] = -1; } for ( i = 0; i < nb_trans + nb_items; i++ ) { printf("%d ", bdd[i]); } printf("\n"); }

  • Building a QueryExpression where name field is either A or B

    - by Mike
    I'm trying to build a Dynamics CRM 4 query so that I can get calendar events that are named either "Event A" or "Event B". A QueryByAttribute doesn't seem to do the job as I cannot specify a condition where the field called "event_name" = "Event A" of "event_name" = "Event B". When using the QueryExpression, I've found the FilterExpression applies to the Referencing Entity. I don't know if the FilterExpression can be used on the Referenced Entity at all. The example below is something like what I want to achieve, though this would return an empty result set as it will go looking in the entity called "my_event_response" for a "name" attribute. It's starting to look like I will need to run several queries to get this but this is less efficient than if I can submit it all at once. ColumnSet columns = new ColumnSet(); columns.Attributes = new string[]{ "event_name", "eventid", "startdate", "city" }; ConditionExpression eventname1 = new ConditionExpression(); eventname1.AttributeName = "event_name"; eventname1.Operator = ConditionOperator.Equal; eventname1.Values = new string[] { "Event A" }; ConditionExpression eventname2 = new ConditionExpression(); eventname2.AttributeName = "event_name"; eventname2.Operator = ConditionOperator.Equal; eventname2.Values = new string[] { "Event B" }; FilterExpression filter = new FilterExpression(); filter.FilterOperator = LogicalOperator.Or; filter.Conditions = new ConditionExpression[] { eventname1, eventname2 }; LinkEntity link = new LinkEntity(); link.LinkCriteria = filter; link.LinkFromEntityName = "my_event"; link.LinkFromAttributeName = "eventid"; link.LinkToEntityName = "my_event_response"; link.LinkToAttributeName = "eventid"; QueryExpression query = new QueryExpression(); query.ColumnSet = columns; query.EntityName = EntityName.mbs_event.ToString(); query.LinkEntities = new LinkEntity[] { link }; RetrieveMultipleRequest request = new RetrieveMultipleRequest(); request.Query = query; return (RetrieveMultipleResponse)crmService.Execute(request); I'd appreciate some advice on how to get the data I need.

  • Scriptaculous Sortable.create - Can't hook the dragged element

    - by Tom
    When using Sortable.create I can't seem to get the element that is being dragged. Does Sciptaculous not fully implement all Draggable and Droppable features when you use sortable? Given: Sortable.create("sortArea", {scroll:window, onChange:orderLi}); function orderLi(){ console.log(this.draggables.each(function(e){if(e.dragging==true){return e};})); } My console always shows all the array of draggables. How do I only grab the one that is being dragged?

  • PHP retrieve external program data

    - by kaykun
    Hi, what I want to do is have a PHP script run a program and have it retrieve data somehow from it. For instance the program would parse data from a file and return the data for the PHP script to display. So far I know to call exec("Program.exe"); but would I have to make it create a file with the data then have the PHP script call fopen and get it that way? Is there a better way to do it? Thanks

  • Help with javascript form validation

    - by zac
    I am getting a headache with form validation and hoping that the kind folks here can give me a hand finishing this sucker up I have it basically working except the email validation is very simplistic (only alerts if it is blank but does not actually check it if is a valid email address) and I am relying on ugly alerts but would like to have it reveal a hidden error div instead of the alert. I have this all wrapped up with an age validation check too.. here are the important bits, minus the cookie scripts function checkAge() { valid = true; if ( document.emailForm.email.value== 0 ) { alert ( "Please enter your email." ); valid = false; } if ( document.emailForm.year.selectedIndex == 0 ) { alert ( "Please select your Age." ); valid = false; } var min_age = 13; var year = parseInt(document.forms["emailForm"]["year"].value); var month = parseInt(document.forms["emailForm"]["month"].value) - 1; var day = parseInt(document.forms["emailForm"]["day"].value); var theirDate = new Date((year + min_age), month, day); var today = new Date; if ( (today.getTime() - theirDate.getTime()) < 0) { var el = document.getElementById('emailBox'); if(el){ el.className += el.className ? ' youngOne' : 'youngOne'; } document.getElementById('emailBox').innerHTML = "<img src=\"emailSorry.gif\">" createCookie('age','not13',0) return false; } else { //this part doesnt work either document.getElementById('emailBox').innerHTML = "<img src=\"Success.gif\">" createCookie('age','over13',0) return valid; }; }; var x = readCookie('age'); window.onload=function(){ if (x=='null') { }; if (x=='over13') { }; if (x=='not13') { document.getElementById('emailBox').innerHTML = "<img src=\"emailSorry.gif\">"; }; } can someone please help me figure a better email validation for this bit: if ( document.emailForm.email.value== 0 ) { alert ( "Please enter your email." ); valid = false; } and how would I replace the alert with something that changes a class from hidden to visible? Something like? document.getElementById('emailError').style.display='block'

  • Understanding Haskell's filter

    - by dmindreader
    I understand that Haskell's filter is a high order function (meaning a function that takes another function as a parameter) that goes through a list checking which element fulfills certain boolean condition. I don't quite understand its definition: filter:: (a->Bool)->[a]->[a] filter p [] = [] filter p (x:y) | p x = x:filter p y | otherwise = filter p y I understand that if I pass an empty list to the function, it would just return an empty list, but how do I read the last two lines?

  • Dependency Injection: I don't get where to start!

    - by Andy
    I have several articles about Dependency Injection, and I can see the benefits, especially when it comes to unit testing. The units can me loosely coupled, and mocking of dependencies can be made. The trouble is - I just don't get where to start. Consider this snippet below of (much edited for the purpose of this post) code that I have. I am instantiating a Plc object from the main form, and passing in a communications mode via the Connect method. In it's present form it becomes hard to test, because I can't isolate the Plc from the CommsChannel to unit test it. (Can I?) The class depends on using a CommsChannel object, but I am only passing in a mode that is used to create this channel within the Plc itself. To use dependancy injection, I should really pass in an already created CommsChannel (via an 'ICommsChannel' interface perhaps) to the Connect method, or maybe via the Plc constructor. Is that right? But then that would mean creating the CommsChannel in my main form first, and this doesn't seem right either, because it feels like everything will come back to the base layer of the main form, where everything begins. Somehow it feels like I am missing a crucial piece of the puzzle. Where do you start? You have to create an instance of something somewhere, but I'm struggling to understand where that should be. public class Plc() { public bool Connect(CommsMode commsMode) { bool success = false; // Create new comms channel. this._commsChannel = this.GetCommsChannel(commsMode); // Attempt connection success = this._commsChannel.Connect(); return this._connected; } private CommsChannel GetCommsChannel(CommsMode mode) { CommsChannel channel; switch (mode) { case CommsMode.RS232: channel = new SerialCommsChannel( SerialCommsSettings.Default.ComPort, SerialCommsSettings.Default.BaudRate, SerialCommsSettings.Default.DataBits, SerialCommsSettings.Default.Parity, SerialCommsSettings.Default.StopBits); break; case CommsMode.Tcp: channel = new TcpCommsChannel( TCPCommsSettings.Default.IP_Address, TCPCommsSettings.Default.Port); break; default: // Throw unknown comms channel exception. } return channel; } }

  • AngularJS: download pdf file from the server

    - by Bartosz Bialecki
    I want to download a pdf file from the web server using $http. I use this code which works great, my file only is save as a html file, but when I open it it is opened as pdf but in the browser. I tested it on Chrome 36, Firefox 31 and Opera 23. This is my angularjs code (based on this code): UserService.downloadInvoice(hash).success(function (data, status, headers) { var filename, octetStreamMime = "application/octet-stream", contentType; // Get the headers headers = headers(); if (!filename) { filename = headers["x-filename"] || 'invoice.pdf'; } // Determine the content type from the header or default to "application/octet-stream" contentType = headers["content-type"] || octetStreamMime; if (navigator.msSaveBlob) { var blob = new Blob([data], { type: contentType }); navigator.msSaveBlob(blob, filename); } else { var urlCreator = window.URL || window.webkitURL || window.mozURL || window.msURL; if (urlCreator) { // Try to use a download link var link = document.createElement("a"); if ("download" in link) { // Prepare a blob URL var blob = new Blob([data], { type: contentType }); var url = urlCreator.createObjectURL(blob); $window.saveAs(blob, filename); return; link.setAttribute("href", url); link.setAttribute("download", filename); // Simulate clicking the download link var event = document.createEvent('MouseEvents'); event.initMouseEvent('click', true, true, window, 1, 0, 0, 0, 0, false, false, false, false, 0, null); link.dispatchEvent(event); } else { // Prepare a blob URL // Use application/octet-stream when using window.location to force download var blob = new Blob([data], { type: octetStreamMime }); var url = urlCreator.createObjectURL(blob); $window.location = url; } } } }).error(function (response) { $log.debug(response); }); On my server I use Laravel and this is my response: $headers = array( 'Content-Type' => $contentType, 'Content-Length' => strlen($data), 'Content-Disposition' => $contentDisposition ); return Response::make($data, 200, $headers); where $contentType is application/pdf and $contentDisposition is attachment; filename=" . basename($fileName) .

  • Operator== in derived class never gets called.

    - by Robin Welch
    Can someone please put me out of my misery with this? I'm trying to figure out why a derived operator== never gets called in a loop. To simplify the example, here's my Base and Derived class: class Base { // ... snipped bool operator==( const Base& other ) const { return name_ == other.name_; } }; class Derived : public Base { // ... snipped bool operator==( const Derived& other ) const { return ( static_cast<const Base&>( *this ) == static_cast<const Base&>( other ) ? age_ == other.age_ : false ); }; Now when I instantiate and compare like this ... Derived p1("Sarah", 42); Derived p2("Sarah", 42); bool z = ( p1 == p2 ); ... all is fine. Here the operator== from Derived gets called, but when I loop over a list, comparing items in a list of pointers to Base objects ... list<Base*> coll; coll.push_back( new Base("fred") ); coll.push_back( new Derived("sarah", 42) ); // ... snipped // Get two items from the list. Base& obj1 = **itr; Base& obj2 = **itr2; cout << obj1.asString() << " " << ( ( obj1 == obj2 ) ? "==" : "!=" ) << " " << obj2.asString() << endl; Here asString() (which is virtual and not shown here for brevity) works fine, but obj1 == obj2 always calls the Base operator== even if the two objects are Derived. I know I'm going to kick myself when I find out what's wrong, but if someone could let me down gently it would be much appreciated.

  • Abstract Data Type: Any1 can help me this? thanks..

    - by Aga Hibaya
    Objectives: Implement the Abstract Data Type (ADT) List using dynamically allocated arrays and structures. Description A LIST is an ordered collection of items where items may be inserted anywhere in the list. Implement a LIST using an array as follows: struct list { int *items; // pointer to the array int size; // actual size of the array int count; // number of items in the array }; typedef struct list *List; // pointer to the structure Implement the following functions: a) List newList(int size); - will create a new List and return its pointer. Allocate space for the structure, allocate space for the array, then initialize size and count, return the pointer. b) void isEmpty(List list); c) void display(List list); d) int contains(List list, int item); e) void remove(List list, int i) ; f) void insertAfter(List list,int item, int i); g) void addEnd(List list,int item) - add item at the end of the list – simply store the data at position count, then increment count. If the array is full, allocate an array twice as big as the original. count = 5 size = 10 0 1 2 3 4 5 6 7 8 9 5 10 15 20 30 addEnd(list,40) will result to count = 6 size = 10 0 1 2 3 4 5 6 7 8 9 5 10 15 20 30 40 h) void addFront(List list,int item) - shift all elements to the right so that the item can be placed at position 0, then increment count. Bonus: if the array is full, allocate an array twice as big as the original. count = 5 size = 10 0 1 2 3 4 5 6 7 8 9 5 10 15 20 30 addFront(list,40) will result to count = 6 size = 10 0 1 2 3 4 5 6 7 8 9 40 5 10 15 20 30 i) void removeFront(List list) - shift all elements to the left and decrement count; count = 6 size = 10 0 1 2 3 4 5 6 7 8 9 40 5 10 15 20 30 removeFront(list) will result to count = 5 size = 10 0 1 2 3 4 5 6 7 8 9 5 10 15 20 30 j) void remove(List list,int item) - get the index of the item in the list and then shift all elements to the count = 6 size = 10 0 1 2 3 4 5 6 7 8 9 40 5 10 15 20 30 remove(list,10) will result to count = 5 size = 10 0 1 2 3 4 5 6 7 8 9 40 5 15 20 30 Remarks

  • jQuery: resizing element cuts off parent's background

    - by Justine
    Hi, I've been trying to recreate an effect from this tutorial: http://jqueryfordesigners.com/jquery-look-tim-van-damme/ Unfortunately, I want a background image underneath and because of the resize going on in JavaScript, it gets resized and cut off as well, like so: http://dev.gentlecode.net/dotme/index-sample.html - you can view source there to check the HTML, but basic structure looks like this: <div class="page"> <div class="container"> div.header ul.nav div.main </div> </div> Here is my jQuery code: $('ul.nav').each(function() { var $links = $(this).find('a'), panelIds = $links.map(function() { return this.hash; }).get().join(","), $panels = $(panelIds), $panelWrapper = $panels.filter(':first').parent(), delay = 500; $panels.hide(); $links.click(function() { var $link = $(this), link = (this); if ($link.is('.current')) { return; } $links.removeClass('current'); $link.addClass('current'); $panels.animate({ opacity : 0 }, delay); $panelWrapper.animate({ height: 0 }, delay, function() { var height = $panels.hide().filter(link.hash).show().css('opacity', 1).outerHeight(); $panelWrapper.animate({ height: height }, delay); }); }); var showtab = window.location.hash ? '[hash=' + window.location.hash + ']' : ':first'; $links.filter(showtab).click(); }); In this example, panelWrapper is a div.main and it gets resized to fit the content of tabs. The background is applied to the div.page but because its child is getting resized, it resizes as well, cutting off the background image. It's hard to explain so please look at the link above to see what I mean. I guess what I'm trying to ask is: is there a way to resize an element without resizing its parent? I tried setting height and min-height of .page to 100% and 101% but that didn't work. I tried making the background image fixed, but nada. It also happens if I add the background to the body or even html. Help?

  • How can I inherit an ASP.NET MVC controller and change only the view?

    - by AlexWalker
    I have a controller that's inheriting from a base controller, and I'm wondering how I can utilize all of the logic from the base controller, but return a different view than the base controller uses. The base controller populates a model object and passes that model object to its view, but I'm not sure how I can access that model object in the child controller so that I can pass it to the child controller's view.

  • Two seperate tm structs mirroring each other

    - by BSchlinker
    Here is my current situation: I have two tm structs, both set to the current time I make a change to the hour in one of the structs The change is occurring in the other struct magically.... How do I prevent this from occurring? I need to be able to compare and know the number of seconds between two different times -- the current time and a time in the future. I've been using difftime and mktime to determine this. I recognize that I don't technically need two tm structs (the other struct could just be a time_t loaded with raw time) but I'm still interested in understanding why this occurs. void Tracker::monitor(char* buffer){ // time handling time_t systemtime, scheduletime, currenttime; struct tm * dispatchtime; struct tm * uiuctime; double remainingtime; // let's get two structs operating with current time dispatchtime = dispatchtime_tm(); uiuctime = uiuctime_tm(); // set the scheduled parameters dispatchtime->tm_hour = 5; dispatchtime->tm_min = 05; dispatchtime->tm_sec = 14; uiuctime->tm_hour = 0; // both of these will now print the same time! (0:05:14) // what's linking them?? // print the scheduled time printf ("Current Time : %2d:%02d:%02d\n", uiuctime->tm_hour, uiuctime->tm_min, uiuctime->tm_sec); printf ("Scheduled Time : %2d:%02d:%02d\n", dispatchtime->tm_hour, dispatchtime->tm_min, dispatchtime->tm_sec); } struct tm* Tracker::uiuctime_tm(){ time_t uiucTime; struct tm *ts_uiuc; // give currentTime the current time time(&uiucTime); // change the time zone to UIUC putenv("TZ=CST6CDT"); tzset(); // get the localtime for the tz selected ts_uiuc = localtime(&uiucTime); // set back the current timezone unsetenv("TZ"); tzset(); // set back our results return ts_uiuc; } struct tm* Tracker::dispatchtime_tm(){ time_t currentTime; struct tm *ts_dispatch; // give currentTime the current time time(&currentTime); // get the localtime for the tz selected ts_dispatch = localtime(&currentTime); // set back our results return ts_dispatch; }

  • Using PHP session_id() to Make Sure iframe is Generated by Our Server Dynamically

    - by Michael Robinson
    We use iframes to show ads on our site. Iframes are used to allow us to keep the ad generation code and other site modules separate. As we track ad views on our site, and need to be able to keep an accurate count of which pagetype gets what views, I must ensure that users can't simply copy-paste the iframe in which the ad is loaded onto another site. This would cause ad count to become inflated for this page, and the count would not match the view count of the page the iframe "should" be displayed in. Before anyone says so: no I can't simply compare the page view count with the ad view count, or use the page view count * number of ads per page, as # of ads per page will not necessarily be static. I need to come up with a solution that will allow ads to be shown only for iframes that are generated dynamically and are shown on our pages. I am not familiar with PHP sessions, but from what little reading I have had time to do, the following seems to be to be an acceptable solution: Add "s = session_id()" to the src of the ad's iframe. In the code that receives and processes ad requests, only return (and count) and ad if s == session_id(). Please correct me if I'm wrong, but this would ensure: Ads would only be returned to iframes whose src was generated alongside the rest of the page's content, as is the case during normal use. We can return our logo to ad calls with an invalid session_id. So a simple example would be: One of our pages: <?php session_start(); ?> <div id="someElement"> <!-- EVERYONE LOVES ADS --> <iframe src="http//awesomesite.com/ad/can_has_ad.php?s=<?php echo session_id(); ?>></iframe> </div> ad/can_has_ad.php: <?php session_start(); ?> if($_GET['s'] == session_id()){ echo 'can has ad'; } else{ echo '<img src="http://awesomesite.com/images/canhaslogo.jpg"/>'; } And finally, copied code with static 's' parameter: <!-- HAHA LULZ I WILL SCREW WITH YOUR AD VIEW COUNTS LULZ HAHA --> <iframe src="http//awesomesite.com/ad/can_has_ad.php?s=77f2b5fcdab52f52607888746969b0ad></iframe> Which would give them an iframe showing our awesome site's logo, and not screw with our view counts. I made some basic test cases: two files, one that generates the iframe and echos it, and one that the iframe's src is pointed to, that checks the 's' parameter and shows an appropriate message depending on the result. I copied the iframe into a file and hosted it on a different server, and the correct message was displayed (cannot has ad). So, my question is: Would this work or am I being a PHP session noob, with the above test being a total fluke? Thanks for your time! Edit: I'm trying to solve this without touching the SQL server
