• Read text file into listbox collections

  - by Arcadian

  Hi, i'm new to C#. I need my program to show different parts of the data contained in a txt file into different listboxs (which are on different tabs of a form) so that the user can see the particular block of data they are interested in. the data contained in the txt file looks like this: G30:39:03:31 JG06 G32:56:36:10 JG04 G31:54:69:52 JG04 G36:32:53:11 JG05 G33:50:05:11 JG06 G39:28:81:21 JG01 G39:22:74:11 JG06 G39:51:44:21 JG03 G39:51:52:22 JG01 G39:51:73:21 JG01 G35:76:24:20 JG06 G35:76:55:11 JG01 G36:31:96:11 JG02 G36:31:96:23 JG02 G36:31:96:41 JG03 though much more of it :) The separate listboxes will contain only the lines who's first integer pair matches that listbox's name. For example, all the lines that start "G32" will be added to the G32 listbox. I think the code would start something like: private void ReadToBox() { FileInfo file = new FileInfo("Jumpgate List.JG"); StreamReader objRead = file.OpenText(); while (!objRead.EndOfStream) but i'm not sure where to start in terms of getting it sorted yet. Any help? There's some rep in it for you :D

• Reading text files line by line, with exact offset/position reporting

  - by Benjamin Podszun

  Hi. My simple requirement: Reading a huge ( a million) line test file (For this example assume it's a CSV of some sorts) and keeping a reference to the beginning of that line for faster lookup in the future (read a line, starting at X). I tried the naive and easy way first, using a StreamWriter and accessing the underlying BaseStream.Position. Unfortunately that doesn't work as I intended: Given a file containing the following Foo Bar Baz Bla Fasel and this very simple code using (var sr = new StreamReader(@"C:\Temp\LineTest.txt")) { string line; long pos = sr.BaseStream.Position; while ((line = sr.ReadLine()) != null) { Console.Write("{0:d3} ", pos); Console.WriteLine(line); pos = sr.BaseStream.Position; } } the output is: 000 Foo 025 Bar 025 Baz 025 Bla 025 Fasel I can imagine that the stream is trying to be helpful/efficient and probably reads in (big) chunks whenever new data is necessary. For me this is bad.. The question, finally: Any way to get the (byte, char) offset while reading a file line by line without using a basic Stream and messing with \r \n \r\n and string encoding etc. manually? Not a big deal, really, I just don't like to build things that might exist already..

• Denormalization of large text?

  - by tesmar

  If I have large articles that need to be stored in a database, each associated with many tables would a NoSQL option help? Should I copy the 1000 char articles over multiple "buckets", duplicating them each time they are related to a bucket or should I use a normalized MySQL DB with lots of Memcache?

• Include at text file as is in (Python) Sphinx Docs

  - by Gregg Lind

  (using Python-Sphinx Documentation tool) I have a .txt log file I'd like to build into _build/html unaltered. What do I need to alter in conf.py, index.rst, etc. Here is the layout: src/ index.rst some_doc.rst somefile.txt How do I get somefile.txt into the html build? I tried adding a line like this to index.rst: Contents: .. toctree:: :maxdepth: 2 some_doc "somefile.txt" hoping it would work by magic, but no magic here! Assuming this is even possible, what would I put in some_doc.rst to refer/link to that file? Note Yes, I'm aware I could put it in /static and just be done with it, but that seems like a total hack, and ugly.

• Help with regex - extracting text.

  - by Yeti

  I have 3 separate strings: $d = 'Created on November 25, 2009'; $v = 'Viewed 17,603 times'; $h = '389 hits'; Which needs to be converted to: $d1 = {unix timestamp of November 25, 2009}; $v1 = "17603"; (commas stripped if it exists) $h1 = "389"; What is the most efficient way to do this (possibly with regex)? Any code snippet would be great.

• Change color of text within a RichTextBox in C#

  - by Addie

  I have a RichTextBox that I write a string to every time I click a Form button. The string ends with a newline so each time I add a string, it appends to the bottom of the RichTextBox. Each string begins with the string "Long" or "Short" and ends with Environment.NewLine. I'd like to color each line red if it beings with "Long" and blue if it begins with "Short". How can I do this? If you need further clarification of the question comment below.

• replace the line to add some text

• Encrypt text using a number

  - by Adam Matan

  Project Euler I have recently begun to solve some of the Project Euler riddles. I found the discussion forum in the site a bit frustrating (most of the discussions are closed and poorly-threaded), So I have decided to publish my Python solutions on launchpad for discussion. The problem is that it seems quite unethical to publish these solutions, as it would let other people gain reputation without doing the programming work, which the site deeply discourages. My Encryption problem I want to encrypt my answers so that only those who have already solved the riddles can see my code. The logical key would be the answer to the riddle, which is always numeric. In order to prevent brute-force attacks on my answers, I want to find an encryption algorithm that takes a significantly long time (few seconds) to run. Do you know any such algorithm? I would fancy a Python package, which I can attach to the code, over an external program that might have portability issues. Thanks, Adam

• Searching for Nodes with Specific Text using the Prototype Javascript Framework

  - by Alan Storm

  Does the Prototype Javascript library have a selector that's equivalent to jQuery's :contains()? If not, what would what be "The Prototype Way" to selector/filter-down a list of elements that contains a particular string. For example, using the following $$('#some_div dd a') I may get back an array of 50 or so links. I only want the links that contain the work 'home'. In jQuery I'd do this jQuery('#some_div dd a:contains('home')'); Is it possible to do something similar using Prototype? If not, is there an elegant way to filter out the array of 50 elements that gets returned.

• Regular - Take all numeric characters following a text character

  - by Simon

  Given a string in the format: XXX999999v99 (where X is any alpha character and v is any numeric character and v is a literal v character) how can I get a regex to match the numeric chatacters following the v? So far I've got 'v\d\d' which includes the v but ideally I'd like just the numeric part. As an aside does anyone know of a tool in which you can specify a string to match and have the regex generated? Modifying an existing regex is one thing but I find starting from scratch painful!

• Contenteditable text editor and cursor position

  - by Cal S

  How can I (using jquery or other) insert html at the cursor/caret position of my contenteditable div: <div contenteditable="true">Hello world</div> For example, if the cursor/caret was between "hello" and "world" and the user then clicked a button, eg "insert image", then using javascript, something like <img src=etc etc> would be inserted between "hello" and "world". I hope I've made this clear =S Example code would be greatly appreciated, thanks a lot!

  I have a servlet. But it is not working as desired. Hence for debugging purposes, I want to print statements to the java console(the one that can be opened using the java icon in taskbar). However, if I use System.out.println("message"), it doesnt display in java console. Is there any alternative way where I can display messages to the console from the servlet? Or can anyone suggest me an alternative way to display messages to any other console?

• System.Drawing - bad text rendering using DrawString on top of transparent pixels.

  - by mackenir

  When rendering text into a bitmap, I find that text looks very bad when rendered on top of an area with non-opaque alpha. The problem is progressively worse as the underlying pixels become more transparent. If I had to guess I'd say that when underlying pixels are transparent, the text renderer draws any anti-aliased 'gray' pixels as solid black. Here are some screenshots: Text drawn on top of transparent pixels: Text drawn on top of semi-transparent pixels: Text drawn on opaque pixels: Here is the code used to render the text: g.SmoothingMode = SmoothingMode.HighQuality; g.DrawString("Press the spacebar", Font, Brushes.Black, textLeft, textTop);

• Clean Microsoft Word Pasted Text using JavaScript

  - by OneNerd

  I am using a 'contenteditable' div and enabling PASTE. It is amazing the amount of markup code that gets pasted in from a clipboard copy from Microsoft Word. I am battling this, and have gotten about 1/2 way there using Prototypes' stripTags() function (which unfortunately does not seem to enable me to keep some tags). However, even after that, I wind up with a mind-blowing amount of unneeded markup code. So my question is, is there some function (using JavaScript), or approach I can use that will clean up the majority of this unneeded markup? Thanks -
