  • A simple string array Iteration in C# .NET doesn't work

    - by met.lord
    This is a simple code that should return true or false after comparing each element in a String array with a Session Variable. The thing is that even when the string array named 'plans' gets the right attributes, inside the foreach it keeps iterating only over the first element, so if the Session Variable matches other element different than the first one in the array it never returns true... You could say the problem is right there in the foreach cicle, but I cant see it... I've done this like a hundred times and I can't understand what am I doing wrong... Thank you protected bool ValidatePlans() { bool authorized = false; if (RequiredPlans.Length > 0) { string[] plans = RequiredPlans.Split(','); foreach (string plan in plans) { if (MySessionInfo.Plan == plan) authorized = true; } } return authorized; }

  • Setting last N bits in an array

    - by Martin
    I'm sure this is fairly simple, however I have a major mental block on it, so I need a little help here! I have an array of 5 integers, the array is already filled with some data. I want to set the last N bits of the array to be random noise. [int][int][int][int][int] set last 40 bits [unchanged][unchanged][unchanged][24 bits of old data followed 8 bits of randomness][all random] This is largely language agnostic, but I'm working in C# so bonus points for answers in C#

  • Do bit operations cause programs to run slower?

    - by flashnik
    I'm dealing with a problem which needs to work with a lot of data. Currently its values are represented as an unsigned int. I know that real values do not exceed a limit of 1000. Questions I can use unsigned short to store it. An upside to this is that it'll use less storage space to store the value. Will performance suffer? If I decided to store data as short but all the calling functions use int, it's recognized that I need to convert between these datatypes when storing or extracting values. Will performance suffer? Will the loss in performance be dramatic? If I decided to not use short but just 10 bits packed into an array of unsigned int. What will happen in this case comparing with previous ones?

  • rotate image with php - any degree

    - by Luis
    How to rotate an image with PHP, any degree, without having the filled space? For instance, if I rotate an image 10 degrees, the image rotates fine but the container around (square) gets filled with black. Is it possible to get rid of this, when for example merging 2 images?

  • Nice way to break a reply up into pieces in ruby

    - by ChaosR
    Hello, I'm writing an IRCd. For this topic it doesn't really matter if you know much about IRC. Its a simple code style problem. Quick overview of the problem: No message may be longer than 512 characters If the message is more, it must be broken into pieces The NAMES reply sends all the nicknames of users on a channel, and quickly grows beyond 512 characters. I currently concocted this marvelous piece of code, it works perfectly. However, its just not "ruby-like". This piece of code is more what you expect in some piece of C code. # 11 is the number of all fixed characters combined in the reply pre_length = 11 + servername.length + mynick.length + channel.name.length list = [""] i = 0 channel.nicks.each do |nick, client| list[i+=1] = "" if list[i].length + nick.length + pre_length > 500 list[i] << "#{channel.mode_char(client)}#{client.nick} " end list.each { |l| send_numeric(RPL_NAMREPLY, channel.name, l.strip) } send_numeric(RPL_ENDOFNAMES, channel.name) So my question is, any ideas to do this more nicely? PS. code has been slightly modified to make it easier to understand out-of-context

  • Convert Text with newlines to a List<String>

    - by Vaccano
    I need a way to take a list of numbers in string form to a List object. Here is an example: string ids = "10\r\n11\r\n12\r\n13\r\n14\r\n15\r\n16\r\n17\r\n18\r\n19"; List<String> idList = new List<String>(); idList.SomeCoolMethodToParseTheText(ids); <------+ | foreach (string id in idList) | { | // Do stuff with each id. | } | | // This is the Method that I need ----------------+ Is there something in the .net library so that I don't have to write the SomeCoolMethodToParseTheText myself?

  • Split string var

    - by lidermin
    Hi, I have a question: Let's say I have this string var: string strData = "1|2|3|4||a|b|c|d" Then, I make a Split: strNumbers[] = strData.Split("||"); //something like this, I know It's not this simple I need two separate parts, each one containing this: //strNumbers -> {"1","2","3","4"},{"a","b","c","d"} So that after that, I could do this: string[] strNumArray[] = strNumbers[0].Split('|'); //strNumArray -> '1', '2', '3', '4' And same with the other part (letters). Is it possible? to make this double split with the same character, but the first time the character is repeated twice?. Thanks. PD. I'm using C#.

  • C++ Converting image to integer array

    - by jonathanasdf
    How would I go about converting the pixels in an image (.png file) to an integer array, where each pixel is converted to its ARGB integer equivalent? I would like to do this without using external libraries. Not a 2D integer array by the way, a 1D one (where access is through array[row*width+col]). Thanks.

  • Remove leading zero's from alphanumeic text

    - by cedar715
    I've seen questions to prefix zeros here in SO. But not the other way !! Can you guys suggest me how to remove the leading zeros in alphanumeric text. Are there any built-in APIs or do I need to write a method to trim the leading zero's? Example: 01234 converts to 1234 0001234a converts to 1234a 001234-a converts to 1234-a 101234 remains as 101234 2509398 remains as 2509398 123z remains as 123z 000002829839 converts to 2829839

  • javascript error of unterminated string

    - by OM The Eternity
    I want pass a parameter of javascript functiona which is a string. This javascript function is a hintbox on mousehover.. and the string i am using is like this: Hemmed Finish: Every side/edge (1/2" to 2") of the banner are folded and glued (special vinyl solution) or heat pressed. This is the most common and best finish option. Stitched Finish: Every side/edge (1" to 2") of the banner are folded in the back and stitched/sewed with white thread. This is not a common option as thread can be seen on the banner. Now in the hintbox on mousehover the above given text has to be display as it is displayed above along with the paragraph break.. But when i pass the above as parameter in that function along with appending some backslashes to recognise some punctuation, iots till gives me javascript error of unterminated string... I am doing this: onMouseover="showhint('Hemmed Finish\: Every side/edge \(1/2\'\' to 2\'\'\) of the banner are folded and glued \(special vinyl solution\) or heat pressed. This is the most common and best finish option.Stitched Finish\: Every side/edge \(1\'\' to 2\'\'\) of the banner are folded in the back and stitched/sewed with white thread. This is not a common option as thread can be seen on the banner', this, event, '250px')" pls could u help me in rectifying the issue...

  • I need to pad IP addresses with Zeroes for each octet

    - by Felipe Alvarez
    Starting with a string of an unspecified length, I need to make it exactly 43 characters long (front-padded with zeroes). It is going to contain IP addresses and port numbers. Something like: ### BEFORE # Unfortunately includes ':' colon 66.35.205.123.80-137.30.123.78.52172: ### AFTER # Colon removed. # Digits padded to three (3) and five (5) # characters (for IP address and port numbers, respectively) 066.035.05.123.00080-137.030.123.078.52172 This is similar to the output produced by tcpflow. Programming in Bash. I can provide copy of script if required. If it's at all possible, it would be nice to use a bash built-in, for speed. Is printf suitable for this type of thing?

  • How to invert alternate bits of a number

    - by Cupidvogel
    The problem is how to invert alternate bits of a number, starting from the LSB. Currently what I am doing is first doing a count = -1 while n: n >>= 1 count += 1 to first find the position of the leftmost set bit, then running a loop to invert every alternate bit: i = 0 while i <= count: num ^= 1<<i i += 2 Is there a quick hack solution instead of this rather boring loop solution? Of course, the solution can't make any asumption about the size of the integer.

  • java phone number validation....

    - by user69514
    Here is my problem: Create a constructor for a telephone number given a string in the form xxx-xxx-xxxx or xxx-xxxx for a local number. Throw an exception if the format is not valid. So I was thinking to validate it using a regular expression, but I don't know if I'm doing it correctly. Also what kind of exception would I have to throw? Do I need to create my own exception? public TelephoneNumber(String aString){ if(isPhoneNumberValid(aString)==true){ StringTokenizer tokens = new StringTokenizer("-"); if(tokens.countTokens()==3){ areaCode = Integer.parseInt(tokens.nextToken()); exchangeCode = Integer.parseInt(tokens.nextToken()); number = Integer.parseInt(tokens.nextToken()); } else if(tokens.countTokens()==2){ exchangeCode = Integer.parseInt(tokens.nextToken()); number = Integer.parseInt(tokens.nextToken()); } else{ //throw an excemption here } } } public static boolean isPhoneNumberValid(String phoneNumber){ boolean isValid = false; //Initialize reg ex for phone number. String expression = "(\\d{3})(\\[-])(\\d{4})$"; CharSequence inputStr = phoneNumber; Pattern pattern = Pattern.compile(expression); Matcher matcher = pattern.matcher(inputStr); if(matcher.matches()){ isValid = true; } return isValid; } Hi sorry, yes this is homework. For this assignments the only valid format are xxx-xxx-xxxx and xxx-xxxx, all other formats (xxx)xxx-xxxx or xxxxxxxxxx are invalid in this case. I would like to know if my regular expression is correct

  • C++ exam question on string class implementation

    - by Carlucho
    I just took an exam where i was asked the following: Write the function body of each of the methods GenStrLen, InsertChar and StrReverse for the given code bellow. You must take into consideration the following; How strings are constructed in C++ The string must not overflow Insertion of character increases its length by 1 An empty string is indicated by StrLen = 0 class Strings { private: char str[80]; int StrLen; public: // Constructor Strings() { StrLen=0; }; // A function for returning the length of the string 'str' int GetStrLen(void) { }; // A function to inser a character 'ch' at the end of the string 'str' void InsertChar(char ch) { }; // A function to reverse the content of the string 'str' void StrReverse(void) { }; }; The answer I gave was something like this (see bellow). My one of problem is that used many extra variables and that makes me believe am not doing it the best possible way, and the other thing is that is not working.... class Strings { private: char str[80]; int StrLen; int index; // *** Had to add this *** public: Strings(){ StrLen=0; } int GetStrLen(void){ for (int i=0 ; str[i]!='\0' ; i++) index++; return index; // *** Here am getting a weird value, something like 1829584505306 *** } void InsertChar(char ch){ str[index] = ch; // *** Not sure if this is correct cuz I was not given int index *** } void StrRevrse(void){ GetStrLen(); char revStr[index+1]; for (int i=0 ; str[i]!='\0' ; i++){ for (int r=index ; r>0 ; r--) revStr[r] = str[i]; } } }; I would appreciate if anyone could explain me toughly what is the best way to have answered the question and why. Also how come my professor closes each class function like " }; " i thought that was only used for ending classes and constructors only. Thanks a lot for your help.
