  • iphone - double tap fail safe way

    - by mike
    I am trying to detect double taps on a view, but when the double tap comes, the first tap triggers an action on TouchesBegan, so, before detecting a double tap a single tap is always detected first. How can I make this in a way that just detects the double tap? I cannot use OS 3.x gestures, because I have to make it compatible with old OS versions. thanks

  • Learning HTML - The Process.

    - by Gabe
    So, as recommended, I did the W3Schools HTML and XML tutorials this weekend. I understand the basics. Now should I look to get more depth in HTML, or go straight into learning CSS (and try to keep learning html at the same time)? If the first, where should I go for more advanced HTML tutorials?

  • iPhone SDK - Comparing characters in string

    - by Karl Daniel
    Basically what I'm trying to do is compare 2 strings one from a plist and one from the user's input. I use a while loop to step through each character and compare it and if true then I increase an integer then once the loop has finished I work out the percentage correct / similarity of the plist answer and the user's answer. I seem to be having a problem however as the only return I'm getting is 0. Below is the code I'm using... The code below is all functioning and the question no longer requires answering... Working code... answerLength = boxAnswer.length; //Gets number of characters of first string. plistLength = plistAnswer.length; //Gets number of characters of second string. characterRange = 0; //Sets the variable for which character to look at. charactersCorrect = 0; //Sets the variable of number of matching characters. unichar answerCharacter; //Declares a unichar for the first string. unichar plistCharacter; //Declares a unichar for the second string. while (answerLength > 0 && plistLength > 0) { answerCharacter = [boxAnswer characterAtIndex:characterRange]; //Gets character of first string at the index of the range integer. plistCharacter = [plistAnswer characterAtIndex:characterRange]; //Gets character of second string at the index of the range integer. answerLength--; //Reduces number of characters left to compare. plistLength--; characterRange++; //Increases integer to tell it to look at next character in string. if (answerCharacter == plistCharacter) { //Checks to see if character of first string and character of second string match. charactersCorrect++; //If true increases the number correct. } } //Works out percentage of matching characters out of the total string. totalChar = plistAnswer.length; totalPercentage = (charactersCorrect/totalChar)*100; percentageCorrect.text = [NSString stringWithFormat:@"%i%%",totalPercentage]; Variable Declarations... int answerLength; int plistLength; int characterRange; double totalChar; double charactersCorrect; int totalPercentage;

  • Upgrade TFS 2008 to 2010 on different server

    - by Chen
    Hi, I have been looking for a way to migrate and upgrade our TFS 2008 server to 2010 server preferably without losing any data. I have been looking at the TFS Integration Platform http://tfsintegration.codeplex.com/ and also Visual Studio 2010 TFS Upgrade Guide vs2010upgradeguide.codeplex.com Looking at the document TFS Integration Platform - Migration Guidance.xps using the first link, it seems to suggest that I could preserve all the data by first migrating the TFS 2008 from one server to the other and then upgrade the TFS 2008 to 2010. Is this true? Thank you, Chen

  • Fetch excerpt from Wikipedia article?

    - by Felix
    I've been up and down the Wikipedia API, but I can't figure out if there's a nice way to fetch the excerpt of an article (usually the first paragraph). It would be nice to get the HTML formatting of that paragraph, too. The only way I currently see of getting something that resembles a snippet is by performing a fulltext search (example), but that's not really what I want (too short). Is there any other way to fetch the first paragraph of a Wikipedia article than barbarically parsing HTML/WikiText?

  • problem binding ListBox on ObservableCollection<T>

    - by Fabian
    Hello, I have a strange "problem". Could someone explain me why : If I have in an ObservableCollection, twice (or more time) an item with the same value, then the selections of those values in the ListBox won't work properly ? In fact, what the ListBox is doing when I click on an item(Even in single item selection) : It selects the first item from the ObservableCollection collection with a matching value. so in the case if multiple items with same value are in the collection, then only the first one will be selected !

  • jQuery "Autocomplete" plugin is messing up the order of my data

    - by Max Williams
    I'm using Jorn Zaefferer's Autocomplete plugin on a couple of different pages. In both instances, the order of displayed strings is a little bit messed up. Example 1: array of strings: basically they are in alphabetical order except for General Knowledge which has been pushed to the top: General Knowledge,Art and Design,Business Studies,Citizenship,Design and Technology,English,Geography,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Displayed strings: General Knowledge,Geography,Art and Design,Business Studies,Citizenship,Design and Technology,English,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Note that Geography has been pushed to be the second item, after General Knowledge. The rest are all fine. Example 2: array of strings: as above but with Cross-curricular instead of General Knowledge. Cross-curricular,Art and Design,Business Studies,Citizenship,Design and Technology,English,Geography,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Displayed strings: Cross-curricular,Citizenship,Art and Design,Business Studies,Design and Technology,English,Geography,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Here, Citizenship has been pushed to the number 2 position. I've experimented a little, and it seems like there's a bug saying "put things that start with the same letter as the first item after the first item and leave the rest alone". Kind of mystifying. I've tried a bit of debugging by triggering alerts inside the autocomplete plugin code but everywhere i can see, it's using the correct order. it seems to be just when its rendered out that it goes wrong. Any ideas anyone? max EDIT - reply to Clint Thanks for pointing me at the relevant bit of code btw. To make diagnosis simpler i changed the array of values to ["carrot", "apple", "cherry"], which autocomplete re-orders to ["carrot", "cherry", "apple"]. Here's the array that it generates for stMatchSets: stMatchSets = ({'':[#1={value:"carrot", data:["carrot"], result:"carrot"}, #3={value:"apple", data:["apple"], result:"apple"}, #2={value:"cherry", data:["cherry"], result:"cherry"}], c:[#1#, #2#], a:[#3#]}) So, it's collecting the first letters together into a map, which makes sense as a first-pass matching strategy. What i'd like it to do though, is to use the given array of values, rather than the map, when it comes to populating the displayed list. I can't quite get my head around what's going on with the cache inside the guts of the code (i'm not very experienced with javascript).

  • preg_replace, exact opposite of a preg_match

    - by SoLoGHoST
    I need to do a preg_replace for the exact opposite of this preg_match regular expression: preg_match('#^(\w+/){0,2}\w+\.\w+$#', $string); So I need to replace all strings that are not valid with an empty string - '' So it needs to remove the first / and last / if found, and all non-valid characters, that is the only valid characters are A-Z, a-z, 0-9, _, ., and / (if it's not the first or last characters of the string). How can I accomplish this with the preg_replace? Thanks :)

  • Papervision 3D: How can I force dimensions on a collada file

    - by imadethisthing
    Hey everyone, I'm working with Collada files and I need them to be a certain size. When instantiating them in pv3d you set the filename, materials, and scale. Scale works like a percentage, and there's no way to get the width, height, or depth of the DAE once in flash. I want to be able to specify the size of DAE in 3D space relative to other pv3d native geometry.

  • Tips for learning faster

    - by Helper Method
    When I start to learn something new, a new tool, programming language, etc. it often takes me sooo much time to learn it. In the end, I have a deep understanding (well, most of the time ;-)), but lacking the time for other things also important. Do you know any tips to learn faster without sacrificing too much depth?

  • parsing issue with comma separated csv file

    - by Andrei
    I am trying to extract 4th column from csv file (comma separated, and skipping first 2 header lines) using this command, awk 'NR <2 {next}{FS =","}{print $4}' filename.csv | more However, it doesn't work because the first column cantains comma, thus 4th column is not really 4th. Below is an example of a row: "sdfsdfsd, sfsdf", 454,fgdfg, I_want_this_column,sdfgdg

  • How to dynamically expand a string in C

    - by sa125
    Hi - I have a function that recursively makes some calculations on a set of numbers. I want to also pretty-print the calculation in each recursion call by passing the string from the previous calculation and concatenating it with the current operation. A sample output might look like this: 3 (3) + 2 ((3) + 2) / 4 (((3) + 2) / 4) x 5 ((((3) + 2) / 4) x 5) + 14 ... and so on So basically, the second call gets 3 and appends + 2 to it, the third call gets passed (3) + 2 , etc. My recursive function prototype looks like this: void calc_rec(int input[], int length, char * previous_string); I wrote a 2 helper functions to help me with the operation, but they implode when I test them: /********************************************************************** * dynamically allocate and append new string to old string and return a pointer to it **********************************************************************/ char * strapp(char * old, char * new) { // find the size of the string to allocate int len = sizeof(char) * (strlen(old) + strlen(new)); // allocate a pointer to the new string char * out = (char*)malloc(len); // concat both strings and return sprintf(out, "%s%s", old, new); return out; } /********************************************************************** * returns a pretty math representation of the calculation op **********************************************************************/ char * mathop(char * old, char operand, int num) { char * output, *newout; char fstr[50]; // random guess.. couldn't think of a better way. sprintf(fstr, " %c %d", operand, num); output = strapp(old, fstr); newout = (char*)malloc( 2*sizeof(char)+sizeof(output) ); sprintf(newout, "(%s)", output); free(output); return newout; } void test_mathop() { int i, total = 10; char * first = "3"; printf("in test_mathop\n"); while (i < total) { first = mathop(first, "+", i); printf("%s\n", first); ++i; } } strapp() returns a pointer to newly appended strings (works), and mathop() is supposed to take the old calculation string ("(3)+2"), a char operand ('+', '-', etc) and an int, and return a pointer to the new string, for example "((3)+2)/3". Any idea where I'm messing things up? thanks.
