  • Converting non-delimited text into name/value pairs in Delphi

    - by robsoft
    I've got a text file that arrives at my application as many lines of the following form: <row amount="192.00" store="10" transaction_date="2009-10-22T12:08:49.640" comp_name="blah " comp_ref="C65551253E7A4589A54D7CCD468D8AFA" name="Accrington "/> and I'd like to turn this 'row' into a series of name/value pairs in a given TStringList (there could be dozens of these <row>s in the file, so eventually I will want to iterate through the file breaking each row into name/value pairs in turn). The problem I've got is that the data isn't obviously delimited (technically, I suppose it's space delimited). Now if it wasn't for the fact that some of the values contain leading or trailing spaces, I could probably make a few reasonable assumptions and code something to break a row up based on spaces. But as the values themselves may or may not contain spaces, I don't see an obvious way to do this. Delphi' TStringList.CommaText doesn't help, and I've tried playing around with Delimiter but I get caught-out by the spaces inside the values each time. Does anyone have a clever Delphi technique for turning the sample above into something resembling this? ; amount="192.00" store="10" transaction_date="2009-10-22T12:08:49.640" comp_name="blah " comp_ref="C65551253E7A4589A54D7CCD468D8AFA" name="Accrington " Unfortunately, as is usually the case with this kind of thing, I don't have any control over the format of the data to begin with - I can't go back and 'make' it comma delimited at source, for instance. Although I guess I could probably write some code to turn it into comma delimited - would rather find a nice way to work with what I have though. This would be in Delphi 2007, if it makes any difference.

  • split a string based on pattern in java - capital letters and numbers

    - by rookie
    Hi all I have the following string "3/4Ton". I want to split it as -- word[1] = 3/4 and word[2] = Ton. Right now my piece of code looks like this:- Pattern p = Pattern.compile("[A-Z]{1}[a-z]+"); Matcher m = p.matcher(line); while(m.find()){ System.out.println("The word --> "+m.group()); } It carries out the needed task of splitting the string based on capital letters like:- String = MachineryInput word[1] = Machinery , word[2] = Input The only problem is it does not preserve, numbers or abbreviations or sequences of capital letters which are not meant to be separate words. Could some one help me out with my regular expression coding problem. Thanks in advance...

  • C# Image HttpHandler: Disable cookies in handler (YSlow / Google PageSpeed)

    - by user319111
    Hi. I have a HttpHandler for resizing images, round corners, reflection etc etc. This i working OK. The problem i have is, that some data is stored in cookies, and the cookies are send to images, when they are shown. Is there any way to disable this globally (cookie-free requests) in web.config, or even in the HttpHandler itself? Example page: http://test.roob.dk/dk/product/ray-ban-rb3359-polarized-16/ Thanks in advance CP // Denmark

  • Get remote image dimensions

    - by o-logn
    Given a URL to an image (and not the image itself), what's the most efficient of getting it's dimensions? I would like to change the height and width attributes in the image tag (<img>) if it is greater than 200x200. However, if it's smaller than that, then I'd like to keep the size as it is. (I'm using ASP.NET/C#)

  • Problem with type coercion and string concatenation in JavaScript in Greasemonkey script on Firefox

    - by Yi Jiang
    I'm creating a GreaseMonkey script to improve the user interface of the 10k tools Stack Overflow uses. I have encountered an unreproducible and frankly bizarre problem that has confounded me and the others in the JavaScript room on SO Chat. We have yet to find the cause after several lengthy debugging sessions. The problematic script can be found here. Source - Install The problem occurs at line 85, the line after the 'vodoo' comment: return (t + ' (' + +(+f.offensive + +f.spam) + ')'); It might look a little weird, but the + in front of the two variables and the inner bracket is for type coercion, the inner middle + is for addition, and the other ones are for concatenation. Nothing special, but observant reader might note that type coercion on the inner bracket is unnecessary, since both are already type coerced to numbers, and type coercing result is useless when they get concatenated into a string anyway. Not so! Removing the + breaks the script, causing f.offensive and f.spam to be concatenated instead of added together. Adding further console.log only makes things more confusing: console.log(f.offensive + f.spam); // 50 console.log('' + (+f.offensive + +f.spam)); // 5, but returning this yields 50 somehow console.log('' + (+f.offensive + +f.spam) + ''); // 50 Source: http://chat.stackoverflow.com/transcript/message/203261#203261 The problem is that this is unreproducible - running scripts like console.log('a' + (+'3' + +'1') + 'b'); in the Firebug console yields the correct result, as does (function(){ return 'a' + (+'3' + +'1') + 'b'; })(); Even pulling out large chunks of the code and running them in the console does not reproduce this bug: $('.post-menu a[id^=flag-post-]').each(function(){ var f = {offensive: '4', spam: '1'}; if(f){ $(this).text(function(i, t){ // Vodoo - please do not remove the '+' in front of the inner bracket return (t + ' (' + +(+f.offensive + +f.spam) + ')'); }); } }); Tim Stone in the chatroom has reproduction instruction for those who are below 10k. This bug only appears in Firefox - Chrome does not appear to exhibit this problem, leading me to believe that this may be a problem with either Firefox's JavaScript engine, or the Greasemonkey add-on. Am I right? I can be found in the JavaScript room if you want more detail and/or want to discuss this.

  • How do I convert CamelCase into human-readable names in Java?

    - by Frederik
    I'd like to write a method that converts CamelCase into a human-readable name. Here's the test case: public void testSplitCamelCase() { assertEquals("lowercase", splitCamelCase("lowercase")); assertEquals("Class", splitCamelCase("Class")); assertEquals("My Class", splitCamelCase("MyClass")); assertEquals("HTML", splitCamelCase("HTML")); assertEquals("PDF Loader", splitCamelCase("PDFLoader")); assertEquals("A String", splitCamelCase("AString")); assertEquals("Simple XML Parser", splitCamelCase("SimpleXMLParser")); assertEquals("GL 11 Version", splitCamelCase("GL11Version")); }

  • Hyphenate a random string to an exact format

    - by chrissygormley
    Hello, I am creating a random ID using the below code: from random import * import string # The characters to make up the random password chars = string.ascii_letters + string.digits def random_password(): return "".join(choice(chars) for x in range(32)) This will output something like: 60ff612332b741508bc4432e34ec1d3e I would like the format to be in this format: 60ff6123-32b7-4150-8bc4-432e34ec1d3e I was looking at the .split() method but can't see how to do this with a random id, also the hyphen's must be at these places so splitting them by a certain amount of digits is out. I'm asking is there a way to split these random id's by 8 number's then 4 etc. Thanks

  • Python os.path.join on Windows

    - by Jim
    I am trying to learn python and am making a program that will output a script. I want to use os.path.join, but am pretty confused. According to the docs if I say: os.path.join('c:', 'sourcedir') I get "C:sourcedir". According to the docs, this is normal, right? But when I use the copytree command, Python will output it the desired way, for example: import shutil src = os.path.join('c:', 'src') dst = os.path.join('c':', 'dst') shutil.copytree(src, dst) Here is the error code I get: WindowsError: [Error 3] The system cannot find the path specified: 'C:src/*.*' If I wrap the os.path.join with os.path.normpath I get the same error. If this os.path.join can't be used this way, then I am confused as to its purpose. According to the pages suggested by Stack Overflow, slashes should not be used in join—that is correct, I assume?

  • C# - split String into smaller Strings by length variable

    - by tyndall
    I'd like to break apart a String by a certain length variable. It needs to bounds check so as not explode when the last section of string is not as long as or longer than the length. Looking for the most succinct (yet understandable) version. Example: string x = "AAABBBCC"; string[] arr = x.SplitByLength(3); // arr[0] -> "AAA"; // arr[1] -> "BBB"; // arr[2] -> "CC"

  • translate by replacing words inside existing text

    - by Berry Tsakala
    What are common approaches for translating certain words (or expressions) inside a given text, when the text must be reconstructed (with punctuations and everythin.) ? The translation comes from a lookup table, and covers words, collocations, and emoticons like L33t, CUL8R, :-), etc. Simple string search-and-replace is not enough since it can replace part of longer words (cat dog ? caterpillar dogerpillar). Assume the following input: s = "dogbert, started a dilbert dilbertion proces cat-bert :-)" after translation, i should receive something like: result = "anna, started a george dilbertion process cat-bert smiley" I can't simply tokenize, since i loose punctuations and word positions. Regular expressions, works for normal words, but don't catch special expressions like the smiley :-) but it does . re.sub(r'\bword\b','translation',s) ==> translation re.sub(r'\b:-\)\b','smiley',s) ==> :-) for now i'm using the above mentioned regex, and simple replace for the non-alphanumeric words, but it's far from being bulletproof. (p.s. i'm using python)

  • How do I get 3 lines of text from a paragraph in C#

    - by Keltex
    I'm trying to create an "snippet" from a paragraph. I have a long paragraph of text with a word hilighted in the middle. I want to get the line containing the word before that line and the line after that line. I have the following piece of information: The text (in a string) The lines are deliminated by a NEWLINE character \n I have the index into the string of the text I want to hilight A couple other criteria: If my word falls on first line of the paragraph, it should show the 1st 3 lines If my word falls on the last line of the paragraph, it should show the last 3 lines Should show the entire paragraph in the degenative cases (the paragraph only has 1 or 2 lines) Here's an example: This is the 1st line of CAT text in the paragraph This is the 2nd line of BIRD text in the paragraph This is the 3rd line of MOUSE text in the paragraph This is the 4th line of DOG text in the paragraph This is the 5th line of RABBIT text in the paragraph Example, if my index points to BIRD, it should show lines 1, 2, & 3 as one complete string like this: This is the 1st line of CAT text in the paragraph This is the 2nd line of BIRD text in the paragraph This is the 3rd line of MOUSE text in the paragraph If my index points to DOG, it should show lines 3, 4, & 5 as one complete string like this: This is the 3rd line of MOUSE text in the paragraph This is the 4th line of DOG text in the paragraph This is the 5th line of RABBIT text in the paragraph etc. Anybody want to help tackle this?

  • High performance text file parsing in .net

    - by diamandiev
    Here is the situation: I am making a small prog to parse server log files. I tested it with a log file with several thousand requests (between 10000 - 20000 don't know exactly) What i have to do is to load the log text files into memory so that i can query them. This is taking the most resources. The methods that take the most cpu time are those (worst culprits first): string.split - splits the line values into a array of values string.contains - checking if the user agent contains a specific agent string. (determine browser ID) string.tolower - various purposes streamreader.readline - to read the log file line by line. string.startswith - determine if line is a column definition line or a line with values there were some others that i was able to replace. For example the dictionary getter was taking lots of resources too. Which i had not expected since its a dictionary and should have its keys indexed. I replaced it with a multidimensional array and saved some cpu time. Now i am running on a fast dual core and the total time it takes to load the file i mentioned is about 1 sec. Now this is really bad. Imagine a site that has tens of thousands of visits a day. It's going to take minutes to load the log file. So what are my alternatives? If any, cause i think this is just a .net limitation and i can't do much about it.

  • using bash: write bit representation of integer to file

    - by theseion
    Hullo First, I want to use bash for this and the script should run on as many systems as possible (I don't know if the target system will have python or whatever installed). Here's the problem: I have a file with binary data and I need to replace a few bytes in a certain position. I've come up with the following to direct bash to the offset and show me that it found the place I want: dd bs=1 if=file iseek=24 conv=block cbs=2 | hexdump Now, to use "file" as the output: echo anInteger | dd bs=1 of=hextest.txt oseek=24 conv=block cbs=2 This seems to work just fine, I can review the changes made in a hex editor. Problem is, "anInteger" will be written as the ASCII representation of that integer (which makes sense) but I need to write the binary representation. How do I tell the command to convert the input to binary (possibly from a hex)?

  • Using bitwise operators on > 32 bit integers

    - by dqhendricks
    I am using bitwise operations in order to represent many access control flags within one integer. ADMIN_ACCESS = 1; EDIT_ACCOUNT_ACCESS = 2; EDIT_ORDER_ACCESS = 4; var myAccess = 3; // ie: ( ADMIN_ACCESS | EDIT_ACCOUNT_ACCESS ) if ( myAccess & EDIT_ACCOUNT_ACCESS ) { // check for correct access // allow for editing of account } Most of this is occurring on the PHP side of my project. There is one piece however where Javascript is used to join several access flags using | when saving someone's access level. This works fine to a point. I have found that once an integer (flag) gets too large ( 32bit), it no longer works correctly with bitwise operators in Javascript. For instance: alert( 4294967296 | 1 ); // equals 1, but should equal 4294967297 I am trying to find a workaround for this so that I do not have to limit my number of access control flags to 32. Each access control flag is two times the previous control flag so that each control flag will not interfere with other control flags. dec(4) = bin(100) dec(8) = bin(1000) dec(16) = bin(10000) I have noticed that when adding two of these flags together with a simple +, it seems to come out with the same answer as a bitwise or operation, but am having trouble wrapping my head around whether this is a simple substitution, or if there might be problems with doing this. Can anyone comment on the validity of this workaround? Example: (4294967296 | 262144 | 524288) == (4294967296 + 262144 + 524288)

  • How to detect Java agents, JVMTI, etc...

    - by Andrew Westberg
    How does one secure the Java environment when running on a machine you don't control? What is to stop someone from creating a java agent or native JVMTI agent and dumping bytecode or re-writing classes to bypass licensing and/or other security checks? Is there any way to detect if any agents are running from Java code? From JNI? From a JVMTI agent?

  • Windows 32 or 64 bit using HKEY_LOCAL_MACHINE\Software\WOW6432 Node

    - by JimDel
    I'm looking for a very simple way of determining if the version of Windows the customer is using is 32bit or 64bit. I know there are ways using .NEt but I'm looking to avoid them. I simply want to use something similar the below pseudo code and want to know if this method can be reliable. If Registry Key exists (HKEY_LOCAL_MACHINE\Software\WOW6432Node) Then Assume 64bit else Assume 32bit Thanks! EDIT: To be more specific, I know there a several different ways to accomplish the goal of finding out if the OS is 32 or 64bit. But I want to know if the above alone method would be reliable.

  • Deployment Setup (.Net) - Search target machine -> Registry search (64 bit)

    - by Joonas Kirsebom
    I have a windows installer project which installs some software (winform, service, mce addin). During the installation I need to search the machine for a registry key. This is done with with the "Launch Condition" - "Add Registry Search" (Deployment Project). I have filled out all the properties right, and checked against the regestry that the value actually can be found. The problem is that the "Registry Search" searches in the x86 part of the registry (HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\...) although my system is a x64 and the deployment setup is also set to x64. Does anyone know how to force the "Registry Search" to search the x64 registry? Or know about a workaround? The weird thing about this, is that Registry setting in the deployment setup is writing to the right registry (x64). My idea is that the "Registry Search" program is only developed to the x86 architecture, and therefore can't read the right registry. I found this article from microsoft, so it seams that they know about this problem. https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=110105&wa=wsignin1.0#details My system is: Windows 7 64bit Visual Studio 2008

  • How can I remove certain characters from inside angle-brackets, leaving the characters outside alone

    - by Iain Fraser
    Edit: To be clear, please understand that I am not using Regex to parse the html, that's crazy talk! I'm simply wanting to clean up a messy string of html so it will parse Edit #2: I should also point out that the control character I'm using is a special unicode character - it's not something that would ever be used in a proper tag under any normal circumstances Suppose I have a string of html that contains a bunch of control characters and I want to remove the control characters from inside tags only, leaving the characters outside the tags alone. For example Here the control character is the numeral "1". Input The quick 1<strong>orange</strong> lemming <sp11a1n 1class1='jumpe111r'11>jumps over</span> 1the idle 1frog Desired Output The quick 1<strong>orange</strong> lemming <span class='jumper'>jumps over</span> 1the idle 1frog So far I can match tags which contain the control character but I can't remove them in one regex. I guess I could perform another regex on my matches, but I'd really like to know if there's a better way. My regex Bear in mind this one only matches tags which contain the control character. <(([^>])*?`([^>])*?)*?> Thanks very much for your time and consideration. Iain Fraser

  • How to Use Calculated Color Values with ColorMatrix?

    - by Otaku
    I am changing color values of each pixel in an image based on a calculation. The problem is that this takes over 5 seconds on my machine with a 1000x1333 image and I'm looking for a way to optimize it to be much faster. I think ColorMatrix may be an option, but I'm having a difficult time figure out how I would get a set of pixel RGB values, use that to calculate and then set the new pixel value. I can see how this can be done if I was just modifying (multiplying, subtracting, etc.) the original value with ColorMatrix, but now how I can use the pixels returned value to use it to calculate and new value. For example: Sub DarkenPicture() Dim clrTestFolderPath = "C:\Users\Me\Desktop\ColorTest\" Dim originalPicture = "original.jpg" Dim Luminance As Single Dim bitmapOriginal As Bitmap = Image.FromFile(clrTestFolderPath + originalPicture) Dim Clr As Color Dim newR As Byte Dim newG As Byte Dim newB As Byte For x = 0 To bitmapOriginal.Width - 1 For y = 0 To bitmapOriginal.Height - 1 Clr = bitmapOriginal.GetPixel(x, y) Luminance = ((0.21 * (Clr.R) + (0.72 * (Clr.G)) + (0.07 * (Clr.B))/ 255 newR = Clr.R * Luminance newG = Clr.G * Luminance newB = Clr.B * Luminance bitmapOriginal.SetPixel(x, y, Color.FromArgb(newR, newG, newB)) Next Next bitmapOriginal.Save(clrTestFolderPath + "colorized.jpg", ImageFormat.Jpeg) End Sub The Luminance value is the calculated one. I know I can set ColorMatrix's M00, M11, M22 to 0, 0, 0 respectively and then put a new value in M40, M41, M42, but that new value is calculated based of a value multiplication and addition of that pixel's components (((0.21 * (Clr.R) + (0.72 * (Clr.G)) + (0.07 * (Clr.B)) and the result of that - Luminance - is multiplied by the color component). Is this even possible with ColorMatrix?
