  • Split a string by two characters

    - by David
    Hi, Firstable i want to match if a string has the following format: $abc #xyz or $abc .xyz. The abc and xyz mean only alphanumeric string. If it's matched then i need to extract the first $abc and the last #xyz, all that using pure javascript and maybe regex. The pattern is in the following order: Dollar Sign Unlimited alphanumeric string space a hash or point Unlimited alphanumeric string Thanks in advance for any help.

  • Converting upper-case string into title-case using Ruby

    - by wsb3383
    Hi, all. I'm trying to convert an all-uppercase string in Ruby into a lower case one, but with each word's first character being upper case. Example: convert "MY STRING HERE" to "My String Here". I know I can use the .downcase method, but that would make everything lower case ("my string here"). I'm scanning all lines in a file and doing this change, so is there a regular expression I can use through ruby to achieve this? Thanks!

  • Validate a string

    - by Activist
    I'm not that good with regular expressions... I need a JavaScript regular expression that will do the following: The string can contain letters (upper and lower case), but not punctuations such as éàïç... The string can contain numbers (0..9) anywhere in the string, except on the first position. The string can contain underscores (_). Valid strings: foo foo1 foo_bar fooBar Invalid strings: 1foo -- number as first character foo bar -- space föo -- punctuation ö Many thanks!

  • JavaScript: add or subtract from number in string

    - by yoavf
    I have a string that looks like "(3) New stuff" where 3 can be any number. I would like to add or subtract to this number. I figured out the following way: var thenumber = string.match((/\d+/)); thenumber++; string = string.replace(/\(\d+\)/ ,'('+ thenumber +')'); Is there a more elegant way to do it?

  • Use textbox value on submit as a query string variable

    - by Eric
    How would I take a text box value and use it in the query string on submit? I'd like it to start as this, /News?favorites=True and end up something like this after the user enters in a search and clicks search. /News?query=test&favorites=True The controller action looks like this public ActionResult Index(string query,bool favorites) { //search code } This question is something close to what I'd like to do, but I'd like to use the query string and maintain the existing values in the query string. Thanks.

  • C++ class is not recognizing string data type

    - by reallythecrash
    I'm working on a program from my C++ textbook, and this this the first time I've really run into trouble. I just can't seem to see what is wrong here. Visual Studio is telling me Error: identifier "string" is undefined. I separated the program into three files. A header file for the class specification, a .cpp file for the class implementation and the main program file. These are the instructions from my book: Write a class named Car that has the following member variables: year. An int that holds the car's model year. make. A string that holds the make of the car. speed. An int that holds the car's current speed. In addition, the class should have the following member functions. Constructor. The constructor should accept the car's year and make as arguments and assign these values to the object's year and make member variables. The constructor should initialize the speed member variable to 0. Accessors. Appropriate accessor functions should be created to allow values to be retrieved from an object's year, make and speed member variables. There are more instructions, but they are not necessary to get this part to work. Here is my source code: // File Car.h -- Car class specification file #ifndef CAR_H #define CAR_H class Car { private: int year; string make; int speed; public: Car(int, string); int getYear(); string getMake(); int getSpeed(); }; #endif // File Car.cpp -- Car class function implementation file #include "Car.h" // Default Constructor Car::Car(int inputYear, string inputMake) { year = inputYear; make = inputMake; speed = 0; } // Accessors int Car::getYear() { return year; } string Car::getMake() { return make; } int Car::getSpeed() { return speed; } // Main program #include <iostream> #include <string> #include "Car.h" using namespace std; int main() { } I haven't written anything in the main program yet, because I can't get the class to compile. I've only linked the header file to the main program. Thanks in advance to all who take the time to investigate this problem for me.

  • Can I use Ubuntu as a wireless media server which performs all decoding/processing server-side?

    - by AthloX
    I want to setup UBUNTU 12.04 desktop as Home media server. I have window 7 netbook and UBUNTU 12.04lts laptop even a samsun galaxy note tablet (android). Two desktop in other room with dualboot win7 and ubuntu. SHARP AQUOS Plasma Tv with Wi-Fi connected. I want to install ubuntu as media server to stream audio/video files over wi-fi. Not only this i want this media server to use its own processing power to decode ans stream so that on remote end only file can play without using their own resource. Is it possible to use ubuntu as media server to stream files without making the remote end to use there own resource. I want only bandwidth of Wi-Fi to be use in this and media center hardware resource.Remote end gadget should use only speaker and screen and not processing power of their own. Please any suggestion is it possible to do so ?

  • image filters for iphone sdk development

    - by plsp
    Hi All, I am planning to develop an iphone app which makes use of image filters like blurring, sharpening,etc. I noticed that there are few approaches for this one, Use openGL ES. I even found an example code on apple iphone dev site. How easy is openGL for somebody who has never used it? Can the image filters be implemented using the openGL framework? There is a Quartz demo as well posted on apple iphone dev site. Has anybody used this framework for doing image processing? How is this approach compared to openGL framework? Don't use openGL and Quartz framework. Basically access the raw pixels from the image and do the manipulation myself. Make use of any custom built image processing libraries like this one. Do you know of any other libraries like this one? Can anybody provide insights/suggestions on which option is the best? Your opinions are highly appreciated. Thanks!

  • GPGPU programming with OpenGL ES 2.0

    - by Albus Dumbledore
    I am trying to do some image processing on the GPU, e.g. median, blur, brightness, etc. The general idea is to do something like this framework from GPU Gems 1. I am able to write the GLSL fragment shader for processing the pixels as I've been trying out different things in an effect designer app. I am not sure however how I should do the other part of the task. That is, I'd like to be working on the image in image coords and then outputting the result to a texture. I am aware of the gl_FragCoords variable. As far as I understand it it goes like that: I need to set up a view (an orthographic one maybe?) and a quad in such a way so that the pixel shader would be applied once to each pixel in the image and so that it would be rendering to a texture or something. But how can I achieve that considering there's depth that may make things somewhat awkward to me... I'd be very grateful if anyone could help me with this rather simple task as I am really frustrated with myself. UPDATE It seems I'll have to use an FBO, getting one like this: glBindFramebuffer(...)

  • SSAS Cube reprocessing fails - then succeeds if I try again

    - by EdgarVerona
    So I'm basically brand new to the concept of BI, and I've inherited an existing ETL process that is a two step process: 1) Loads the data into a database that is only used by the cube processing 2) Starts off the SSAS cube processing against said database It seems pretty well isolated, but occasionally (once a week, sometimes twice) it will fail with the following exception: "Errors in the OLAP storage engine: The attribute key cannot be found" Now the interesting thing is that: 1) The dimension having the issue is not usually the same one (i.e. there's no single dimension that consistently has this failure) 2) The source table, when I inspect it, does actually contain the attribute key that it says could not be found And, most interestingly... 3) If I then immediately reprocess the dimensions and cubes manually through SSMS, they reprocess successfully and without incident. In both the aforementioned job and when I reprocess them through SSMS, I am using "ProcessFull", so it should be reprocessing them completely. Has anyone run into such an issue? I'm scratching my head about it... because if it was a genuine data integrity issue, reprocessing the cube again wouldn't fix it. What on earth could be happening? I've been tasked with finding out why this happens, but I can neither reproduce it consistently nor can I point to a data integrity problem as the root cause. Thanks for any input you can provide!

  • How to pass dynamic parameters to .pde file

    - by Kalpana
    class Shape contains two methods drawCircle() and drawTriangle(). Each function takes different set of arguments. At present, I invoke this by calling the pde file directly. How to pass these arguments from a HTML file directly if I have to control the arguments being passed to the draw function? 1) Example.html has (current version) <script src="processing-1.0.0.min.js"></script> <canvas data-processing-sources="example.pde"></canvas> 2) Example.pde has class Shape { void drawCircle(intx, int y, int radius) { ellipse(x, y, radius, radius); } void drawTriangle(int x1, int y1, int x2, int y2, int x3, int y3) { rect(x1, y1, x2, y2, x3, y3); } } Shape shape = new Shape(); shape.drawCircle(10, 40, 70); I am looking to do something like this in my HTML file, so that I can move all the functions into a separate file and call them with different arguments to draw different shapes (much similar to how you would do it in Java) A.html <script> Shape shape = new Shape(); shape.drawCircle(10, 10, 3); </script> B.html <script> Shape shape = new Shape(); shape.drawTriangle(30, 75, 58, 20, 86, 75); </script> 2) Iam using Example2.pde has void setup() { size(200,200); background(125); fill(255); } void rectangle(int x1, int y1, int x2, int y2) { rect(x1, y1, x2, y2); } My Example2.html has var processingInstance; processingInstance.rectangle(30, 20, 55, 55); but this is not working. How to pass these parameters dynamically from html.

  • Projective transformation

    - by mcwehner
    Given two image buffers (assume it's an array of ints of size width * height, with each element a color value), how can I map an area defined by a quadrilateral from one image buffer into the other (always square) image buffer? I'm led to understand this is called "projective transformation". I'm also looking for a general (not language- or library-specific) way of doing this, such that it could be reasonably applied in any language without relying on "magic function X that does all the work for me". An example: I've written a short program in Java using the Processing library (processing.org) that captures video from a camera. During an initial "calibrating" step, the captured video is output directly into a window. The user then clicks on four points to define an area of the video that will be transformed, then mapped into the square window during subsequent operation of the program. If the user were to click on the four points defining the corners of a door visible at an angle in the camera's output, then this transformation would cause the subsequent video to map the transformed image of the door to the entire area of the window, albeit somewhat distorted.

  • BufferedImage & ColorModel in Java

    - by spol
    I am using a image processing library in java to manipulate images.The first step I do is I read an image and create a java.awt.Image.BufferedImage object. I do it in this way, BufferedImage sourceImage = ImageIO.read( new File( filePath ) ); The above code creates a BufferedImage ojbect with a DirectColorModel: rmask=ff0000 gmask=ff00 bmask=ff amask=0. This is what happens when I run the above code on my macbook. But when I run this same code on a linux machine (hosted server), this creates a BufferedImage object with ColorModel: #pixelBits = 24 numComponents = 3 color space = java.awt.color.ICC_ColorSpace@c39a20 transparency = 1 has alpha = false isAlphaPre = false. And I use the same jpg image in both the cases. I don't know why the color model on the same image is different when run on mac and linux. The colormodel for mac has 4 components and the colormodel for linux has 3 components.There is a problem arising because of this, the image processing library that I use always assumes that there are always 4 components in the colormodel of the image passed, and it throws array out of bounds exception when run on linux box. But on macbook, it runs fine. I am not sure if I am doing something wrong or there is a problem with the library. Please let me know your thoughts. Also ask me any questions if I am not making sense!

  • Linq: convert string to int array

    - by Oops
    I have a function (tointarray) to convert a string into an array of ints, but I am not very satisfied with it. it does the job but there must be a more elegant way to do this, perhaps Linq could help here. unfortunately I am not very good in Linq. do you guys know a better way? my function: { string s1 = "1;2;3;4;5;6;7;8;9;10;11;12"; int[] ia = tointarray(s1, ';'); } int[] tointarray(string value, char sep) { string[] sa = value.Split(sep); int[] ia = new int[sa.Length]; for (int i = 0; i < ia.Length; ++i) { int j; string s = sa[i]; if (int.TryParse(s, out j)) { ia[i] = j; } } return ia; }

  • C# Modify Connection String that exists inside a library

    - by LnDCobra
    I have a Class Library, which inside just has a DataSet (MySQL connector) and a Connector class. I use this class in multiple projects to connect to the database, and I always had the password embedded in the connection string but now I need to be able to modify this string(for security purposes) so I can have the user connect using their own account. How can I modify this connection string. I have tried the following Properties.Settings.Default.DataBaseConnectionString = "String"; But it seems that the connection string is readonly becase it doesn't appear to have a setter value. I also tried the following with no luck Properties.Settings.Default.DatabaseConnectionString.Insert( Properties.Settings.Default.DatabaseConnectionConnectionString.Length - 1, "Password=dbpassword;");

  • HTML encode UTF-8 string gets mangled into latin1

    - by Ken Mayer
    I'm parsing my nginx logs, and I want to discover some details from the HTTP_REFERER string, for example, the query string used to find the web site. One user typed in "México" which gets encoded in the log as "query=M%E9xico". Passing this through Rack::Utils.parse_query('query=M%E9xico') you get a hash, {"query" = "M?xico"} When you to stuff "M?exico" into Postgres (but not the more forgiving SQLite), it pukes because the string isn't proper UTF-8. Looking at http://rack.rubyforge.org/doc/Rack/Utils.html#M000324, unescape is packing a hex string. How can I convert the string back to UTF-8, or can I get parse_query to return UTF-8 in the first place.

  • Binary to strings as binary? C #/.NET

    - by acidzombie24
    Redis keys are binary safe. I'd like to mess around and put binary into redis using C#. My client of choice doesn't support writing binary keys it uses keys and it make sense. However i am just fooling around so tell me how i can do this. How do i convert a raw byte[] into a string? At first i was thinking about converting a byte[] to a utf8 string however unicode has some checks to see if its valid or not. So raw binary should fail. Actually i tried it out. Instead of failing i got a strange result. My main question is how do i convert a raw byte[] to the equivalent string? My unimportant question is why did i get a 512 byte string instead of an exception saying this is not a valid UTF8 string? code var rainbow = new byte[256]; for (int i = 0; i < 256; i++) { rainbow[i] = (byte)i; } var sz = Encoding.UTF8.GetString(rainbow); var szarr = Encoding.UTF8.GetBytes(sz); Console.WriteLine("{0} {1} {2}", ByteArraysEqual(szarr, rainbow), szarr.Length, rainbow.Length); Output False 512 256
