  • A specific string format with a number and character together represeting a certain item

    - by sil3nt
    Hello there, I have a string which looks like this "a 3e,6s,1d,3g,22r,7c 3g,5r,9c 19.3", how do I go through it and extract the integers and assign them to its corresponding letter variable?. (i have integer variables d,r,e,g,s and c). The first letter in the string represents a function, "3e,6s,1d,3g,22r,7c" and "3g,5r,9c" are two separate containers . And the last decimal value represents a number which needs to be broken down into those variable numbers. my problem is extracting those integers with the letters after it and assigning them into there corresponding letter. and any number with a negative sign or a space in between the number and the letter is invalid. How on earth do i do this?

  • Copying part of a string in C

    - by wolfPack88
    This seems like it should be really simple, but for some reason, I'm not getting it to work. I have a string called seq, which looks like this: ala ile val I want to take the first 3 characters and copy them into a different string. I use the command: memcpy(fileName, seq, 3 * sizeof(char)); That should make fileName = "ala", right? But for some reason, I get fileName = "ala9". I'm currently working around it by just saying fileName[4] = '\0', but was wondering why I'm getting that 9. Note: After changing seq to ala ile val ser and rerunning the same code, fileName becomes "alaK". Not 9 anymore, but still an erroneous character.

  • PHP String tokenizer not working correctly

    - by asdadas
    I have no clue why strtok decided to break on me. Here is my code. I am tokenizing a string by dollar symbol $. echo 'Tokenizing this by $: ',$aliases,PHP_EOL; if(strlen($aliases) > 0) { //aliases check $token = strtok($aliases, '$'); while($token != NULL) { echo 'Found a token: ',$token,PHP_EOL; if(!isGoodLookup($token)) { echo 'ERROR: Invalid alias found.',PHP_EOL; stop($db); } $goodAliasesList[] = $token; $token = strtok('$'); } if($token == NULL) echo 'Found null token, moving on',PHP_EOL; } And this is my output: Tokenizing this by $: getaways$aaa Found a token: getaways Found null token, moving on str tok is not supposed to do this!! where is my aaa token!!

    %# load a grayscale image img = imread('coins.png'); %# display the image figure imshow(img,[]); %# false-color colormap('hot') The above code is from here: http://stackoverflow.com/questions/2592755/infrared-image-processing-in-matlab/2592793#2592793 But I don't understand how figure(What's the difference with/without it?) and colormap(How does it affect the already shown img?) work?

  • C# String.Replace with a start/index (Added my (slow) implementation)

    - by Chris T
    I'd like an efficient method that would work something like this EDIT: Sorry I didn't put what I'd tried before. I updated the example now. // Method signature, Only replaces first instance or how many are specified in max public int MyReplace(ref string source,string org, string replace, int start, int max) { int ret = 0; int len = replace.Length; int olen = org.Length; for(int i = 0; i < max; i++) { // Find the next instance of the search string int x = source.IndexOf(org, ret + olen); if(x > ret) ret = x; else break; // Insert the replacement source = source.Insert(x, replace); // And remove the original source = source.Remove(x + len, olen); // removes original string } return ret; } string source = "The cat can fly but only if he is the cat in the hat"; int i = MyReplace(ref source,"cat", "giraffe", 8, 1); // Results in the string "The cat can fly but only if he is the giraffe in the hat" // i contains the index of the first letter of "giraffe" in the new string The only reason I'm asking is because my implementation I'd imagine getting slow with 1,000s of replaces.

  • Javascript string replace with calculations

    - by Chris
    Is there a way to resolve mathematical expressions in strings in javascript? For example, suppose I want to produce the string "Tom has 2 apples, Lucy has 3 apples. Together they have 5 apples" but I want to be able to substitute in the variables. I can do this with a string replacement: string = "Tom has X apples, Lucy has Y apples. Together they have Z apples"; string2 = string.replace(/X/, '2').replace(/Y/, '3').replace(/Z/, '5'); However, it would be better if, instead of having a variable Z, I could use X+Y. Now, I could also do a string replace for X+Y and replace it with the correct value, but that would become messy when trying to deal with all the possible in-string calculations I might want to do. I suppose I'm looking for a way to achieve this: string = "Something [X], something [Y]. Something [(X+Y^2)/5X]"; And for the [_] parts to be understood as expressions to be resolved before substituting back into the string. Thanks for your help.

  • What's wrong with this JAVA code for android?

    - by Umair Ashraf
    I have written this piece of code to break an image into 9 pieces and it gives me runtime error. There is no error in LogCat and I am stuck. The error comes at line 7 line from bottom (Bitmap.createBitmap(...);). public Bitmap[] getPieces(Bitmap bmp) { Bitmap[] bmps = new Bitmap[9]; int width = bmp.getWidth(); int height = bmp.getHeight(); int rows = 3; int cols = 3; int cellHeight = height / rows; int cellWidth = width / cols; int piece = 0; for (int x = 0; x <= width; x += cellWidth) { for (int y = 0; y <= height; y += cellHeight) { Bitmap b = Bitmap.createBitmap(bmp, x, y, cellWidth, cellHeight, null, false); bmps[piece] = b; piece++; } } return bmps; }

  • PHP manipulating multidimensional array values

    - by Joker
    I have a result set as an array from a database that looks like: array ( 0 => array ( "a" => "something" "b" => "something" "c" => "something" ) 1 => array ( "a" => "something" "b" => "something" "c" => "something" ) 2 => array ( "a" => "something" "b" => "something" "c" => "something" ) ) How would I apply a function to replace the values of an array only on the array key with b? Normally I would just rebuild a new array with a foreach loop and apply the function if the array key is b, but I'm not sure if it's the best way. I've tried taking a look at many array functions and it seemed like array_walk_recursive is something I might use, but I didn't have luck in getting it to do what I want. If I'm not describing it well enough, basically I want to be able to do as the code below does: $arr = array(); foreach ($result as $key => $value) { foreach ($value as $key2 => $value2) { $arr[$key][$key2] = ($key2 == 'b' ? $this->_my_method($value2) : $value2); } } Should I stick with that, or is there a better way?

  • java.util.BitSet -- set() doesn't work as expected

    - by dwhsix
    Am I missing something painfully obvious? Or does just nobody in the world actually use java.util.BitSet? The following test fails: @Test public void testBitSet() throws Exception { BitSet b = new BitSet(); b.set(0, true); b.set(1, false); assertEquals(2, b.length()); } It's really unclear to me why I don't end up with a BitSet of length 2 and the value 10. I peeked at the source for java.util.BitSet, and on casual inspection it seems to fail to make sufficient distinction between a bit that's been set false and a bit that has never been set to any value... (Note that explicitly setting the size of the BitSet in the constructor has no effect, e.g.: BitSet b = new BitSet(2);

  • Modify strings in Rails?

    - by Daniel O'Connor
    Hey everyone, So I'm new to Rails (teaching myself as a senior project in high school), and I'm trying to figure out how to modify these strings. Let's say someone writes the following string in a form: "you know you are a geek when" How can I automatically change it to this: "You know you are a geek when..."? I need Rails to check the case of the first letter and check for the three dots then modify the string as necessary. I've looked here, but I can't find anything that would work. Thanks a lot!

  • Changing href atributes with nokogiri and ruby on rails

  • Newbie Question: Read and Process a List of Text Files

    - by johnv
    I'm completely new to .NET and am trying as a first step to write a text processing program. The task is simple: I have a list of 10,000 text files stored in one folder, and I'm trying to read each one, store it as a string variable, then run it through a series of functions, then save the final output to another folder. So far I can only manage to manually input the file path like this (in VB.NET): Dim tRead As System.IO.StreamReader Public Function ReadFile() As String Dim EntireFile As String tRead = File.OpenText("c:\textexample\00001.txt") EntireFile = tRead.ReadToEnd Return EntireFile End Function Public Function Step1() ..... End Function Public Function Step2() ..... End Function .............. I'm wondering, therefore, if there's a way to automate this process. Perhaps for example store all input file path into a text file then read each entry at a time, then save the final output into the save path, again listed in a text file. Any help is greatly appreciated. ReplyQuote

  • Inconsistent height of text input elements between Firefox and WebKit

    - by Trevor Burnham
    OK, I realize that this is something of an eternal question, but here goes: I've got a single text input, <input type="text" name="whatever" /> and I've specified its font-family, font-size and padding. Yet, even on the same machine (my Mac, let's say), the input has a different height in Firefox (3.6) than it does in Chrome or Safari. Specifically, Firefox adds a little bit more padding below the text. And no, specifying height in pixels doesn't achieve consistency either. Is there any way to achieve text input height consistency across Gecko- and WebKit-based browsers (let alone IE and Opera) without resorting to JavaScript? And if I must use JavaScript, has someone already devised a jQuery plugin or something to easily do this? Update: Here's what not to do. The jqTransform plugin lets you skin form elements and promises that they'll look the same across browsers. Here's how the demo input looks in Chrome 5 on my Mac: and here's how the same input looks in Firefox 3.6.4: I haven't altered these screenshots in any way, just cropped them. Now, my first reaction is, "Ugh, I don't want to support Firefox." But there are currently more Firefox users than Safari and Chrome users combined, so that's not an option. Someone, please help! I just want my forms to look the same across modern, standards-compliant browsers! And by "look the same," I'm not talking about the outline on selection or anything like that; I'm just talking about having the same width, height, and text placement!

  • Why is a 16-bit register used with BSR instruction in this code snippet?

    - by sharptooth
    In this hardcore article there's a function find_maskwidth() that basically detects the number of bits required to represent itemCount dictinct values: unsigned int find_maskwidth( unsigned int itemCount ) { unsigned int maskWidth, count = itemCount; __asm { mov eax, count mov ecx, 0 mov maskWidth, ecx dec eax bsr cx, ax jz next inc cx mov maskWidth, ecx next: } return maskWidth; } the question is why do they use ax and cx registers instead of eax and ecx?

  • what's the C# equivalent of string$ from basic

    - by Preet Sangha
    And is there an elegant linqy way to do it? What I want to do is create string of given length with made of up multiples of another string up to that length So for length - 9 and input string "xxx" I get "xxxxxxxxx" (ie length 9) for a nun integral multiple then I'd like to truncate the line. I can do this using loops and a StringBuilder easily but I'm looking to see if the language can express this idea easily. (FYI I'm making easter maths homework for my son)

  • Can I fire a Text Changed Event for an asp.net Text Box before it loses focus?

    - by Xaisoft
    I have an asp.net TextBox in which I want to check if the text entered into the TextBox is > 0. It works once I tab out or click out of the TextBox, but if I keep focus on the TextBox, it won't fire the Text Changed Event, so I have the following scenario, I want to enable something if and only if the TextBox.Text.Length = 0. Now, if I put my caret in the TextBox and delete all the characters and then leave the caret in the TextBox so it still has focus and take my mouse and click a button, it will not do what it was supposed to do because it never fired the Text Changed Event. How would something like this be handled?

  • Replacing accented/umlauted characters with their unadorned counterparts in C# [closed]

    - by Andrew Rollings
    Duplicate of 249087 I have a bunch of user generated addresses that may contain characters with diacritic marks. What is the most effective (i.e. generic) way (apart from a straightforward replace) to automatically convert any such characters to their closest English equivalent? E.g. any of àâãäå would become a æ would become the two separate letters ae ç would become c any of èéêë would become e etc. for all possible letter variations (preferably without having to find and encode lookups for each diacritic form of the letter). (Note: I have to pass these addresses on to third party software that is incapable of printing anything other than English characters. I'd rather the software was capable of handling them, but I have no control over that.) EDIT: Never mind... Found the answer [here][2]. It showed up in the "Related" section to the right of the question after I posted, but not in my prior search or as a pre-post suggestion. Hmm. I added the 'diacritics' tag to the other question in any case. EDIT 2: Jeez! Who voted this -1 after I closed it?
