• Checkbox in a Crystal Report

  - by JosephStyons

  What is the best way to display a checkbox in a Crystal Report? Example: My report has a box for "Male" and "Female", and one should be checked. My current workaround is to draw a small graphical square, and line it up with a formula which goes like this: if {table.gender} = "M" then "X" else " " This is a poor solution, because changing the font misaligns my "X" and the box around it, and it is absurdly tedious to squint at the screen and get a pixel-perfect alignment for every box (there are dozens). Does anyone have a better solution? I've thought about using the old-style terminal characters, but I'm not sure if they display properly in Crystal. Edit: I'm using Crystal XI.

• Correct syntax for matching a string inside a variable against an array

  - by Jamex

  Hi, I have a variable, $var, that contains a string of characters, this is a dynamic variable that contains the values from inputs. $var could be 'abc', or $var could be 'blu', I want to match the string inside variable against an array, and return all the matches. $array = array("blue", "red", "green"); What is the correct syntax for writing the code in php, my rough code is below $match = preg_grep($var, $array); (incorrect syntax of course) I tried to put quotes and escape slashes, but so far no luck. Any suggestion? TIA

• Serial numbers generation without user data

  - by Sphynx

  This is a followup to this question. The accepted answer is generally sufficient, but requires user to supply personal information (e.g. name) for generating the key. I'm wondering if it's possible to generate different keys based on a common seed, in a way that program would be able to validate if those keys belong to particular product, but without making this process obvious to the end user. I mean it could be a hash of product ID plus some random sequence of characters, but that would allow user to guess potential new keys. There should be some sort of algorithm difficult to guess.

• How do I generate a random string of up to a certain length?

  - by slavy13

  I would like to generate a random string (or a series of random strings, repetitions allowed) of length between 1 and n characters from some (finite) alphabet. Each string should be equally likely (in other words, the strings should be uniformly distributed). The uniformity requirement means that an algorithm like this doesn't work: alphabet = "abcdefghijklmnopqrstuvwxyz" len = rand(1, n) s = "" for(i = 0; i < len; ++i) s = s + alphabet[rand(0, 25)] (pseudo code, rand(a, b) returns a integer between a and b, inclusively, each integer equally likely) It doesn't work because shorter lengths are as likely as longer ones, meaning it's more likely to generate a shorter string than a longer one, so the result is not uniform.

• what this `^` mean here in solr

  - by Rahul Mehta

  I am confuse her but i want to clear my doubt. I think it is stupid question but i want to know. Use a TokenFilter that outputs two tokens (one original and one lowercased) for each input token. For queries, the client would need to expand any search terms containing upper case characters to two terms, one lowercased and one original. The original search term may be given a boost, although it may not be necessary given that a match on both terms will produce a higher score. text:NeXT ==> (text:NeXT^10 OR text:next) what this ^ mean here . http://wiki.apache.org/solr/SolrRelevancyCookbook#Relevancy_and_Case_Matching

• Need help understanding some Python code

  - by Yarin

  I'm new to Python, and stumped by this piece of code from the Boto project: class SubdomainCallingFormat(_CallingFormat): @assert_case_insensitive def get_bucket_server(self, server, bucket): return '%s.%s' % (bucket, server) def assert_case_insensitive(f): def wrapper(*args, **kwargs): if len(args) == 3 and not (args[2].islower() or args[2].isalnum()): raise BotoClientError("Bucket names cannot contain upper-case " \ "characters when using either the sub-domain or virtual " \ "hosting calling format.") return f(*args, **kwargs) return wrapper Trying to understand what's going on here. What is the '@' symbol in @assert_case_sensitive ? What do the args *args, **kwargs mean? What does 'f' represent? Thanks!

• How does the verbosity of identifiers affect the performance of a programmer?

  - by DR

  I always wondered: Are there any hard facts which would indicate that either shorter or longer identifiers are better? Example: clrscr() opposed to ClearScreen() Short identifiers should be faster to read because there are fewer characters but longer identifiers often better resemble natural language and therefore also should be faster to read. Are there other aspects which suggest either a short or a verbose style? EDIT: Just to clarify: I didn't ask: "What would you do in this case?". I asked for reasons to prefer one over the other, i.e. this is not a poll question. Please, if you can, add some reason on why one would prefer one style over the other.

• Understanding character encoding in typical Java web app

  - by Marcus

  Some pseudocode from a typical web app: String a = "A bunch of text"; //UTF-16 saveTextInDb(a); //Write to Oracle VARCHAR(15) column String b = readTextFromDb(); //UTF-16 out.write(b); //Write to http response In the first line we create a Java String which uses UTF-16. When you save to Oracle VARCHAR(15) does Oracle also store this as UTF-16? Does the length of an Oracle VARCHAR refer to number of Unicode characters (and not number of bytes)? And then when we write b to the ServletResponse is this being written as UTF-16 or are we by default converting to another encoding like UTF-8?

• php - track down premature headers leak

  - by user151841

  I'm using set_cookie() on a site. After adding some functionality, I'm getting Warning: Cannot modify header information - headers already sent by... error. The line number it references as to where the headers initiated from is the very line where set_cookie() is! And I checked, it's not being called twice. How can I track down these premature headers? I looked at the source code and didn't see any stray characters or anything before the error message starts ( I'm using xdebug, so the first thing is a , which I thought was me, but is actually the beginning of the xdebug message ). I've grepped my code for extra echo and so forth -- nothing. Can PHP tell me when and where the headers are starting? Or are they really starting on the set_cookie line, and if so, how have I gotten myself into this situation, and how do I get out?

• Interview question: difference between object and object-oriented languages.

  - by Bar

  My friend was asked the following question: what's the difference between object language and object-oriented language? It's a little unintelligible question. What does term «object language» correspond to? Does that mean «pure» object-oriented language, like the Wikipedia article says: Languages called "pure" OO languages, because everything in them is treated consistently as an object, from primitives such as characters and punctuation, all the way up to whole classes, prototypes, blocks, modules, etc. They were designed specifically to facilitate, even enforce, OO methods. Examples: Smalltalk, Eiffel, Ruby, JADE, VB.NET.

• C++: Can a macro expand "abc" into 'a', 'b', 'c'?

  - by Peter Alexander

  I've written a variadic template that accepts a variable number of char parameters, i.e. template <char... Chars> struct Foo; I was just wondering if there were any macro tricks that would allow me to instantiate this with syntax similar to the following: Foo<"abc"> or Foo<SOME_MACRO("abc")> or Foo<SOME_MACRO(abc)> etc. Basically, anything that stops you from having to write the characters individually, like so Foo<'a', 'b', 'c'> This isn't a big issue for me as it's just for a toy program, but I thought I'd ask anyway.

• Oracle - Determine maximum supported size for regular expression

  - by FrustratedWithFormsDesigner

  I have a regular expression that throws ORA-12733, "regular expression is too long". How do I determine what the maximum supported size is? FYI: the offending regex is 892 characters. It's a generated regex, so I could change how I generate and execute it, but I would like to know what the limits to the max size are before I change how I am generating and executing. (running Oracle 10.2g) UPDATE: If it depends on the actual regex, here's the begining of it (the rest is just the same thing repeated, with different values between ^ and $): (^R_1A$|^R_2A$|^R_3A$|^R_4A$|^R_4B$|^R_5A$|^R_5B$...

• Grouping string by comma between brackets

  - by Myra

  Response to : http://stackoverflow.com/questions/1454913/regular-expression-to-find-a-string-included-between-two-characters-while-exclud Hi,I'm looking for a regex pattern that applies to my string including brackets: [1,2,3,4,5] [abc,ef,g] [0,2,4b,y7] could be anything including word,digit,non-word together or separated. I wish to get the group between brackets by \[(.*?)\] but what is the regex pattern that will give me the group between brackets and sub-group strings separated by commas so that the result may be following ?? Group1 : [1,2,3,4,5] Group1: 1 Group2: 2 Group3: 3 Group4: 4 Group5: 5 Group2 : [abc,ef,g] Group1: abc Group2: ef Group3: g etc .. Thank you for your help

• PHP with SQL Injection

  - by Scott S

  For our first assignment in a System Security class, we have to hack into the professors "cheaply organized" sql database. I know the only user is "admin" and the select statement generated in the php is: select user_id from user where user_username = 'admin' AND user_password = md5('noob') I am having a number of problems attempting to bypass the password part of this statement as the professor has some javascript embedded in the page to sanitize the username and password of any non-alphanumeric values. This can be bypassed by turning off javascript :P but any values sent still get cleaned by the operating system (some build of Debian 32-bit). I've seen the code for the login request and it does not escape any characters. How do I bypass the operating systems escape sequences?

• How to add http headers in suds 0.3.6?

  - by Esabe

  Hi everyone, I have an application in python 2.5 which sends data through suds 0.3.6. The problem is that the data contains non-ascii characters, so I need the following header to exist in the soap message: Content-Type="text/html; charset="utf-8" and the header that exists in the SOAP message is just: Content-Type="text/html" I know that it is fixed in suds 0.4, but it requires Python2.6 and I NEED Python2.5 because I use CentOS and it needs that version. So the question is: How could I change or add new HTTP headers to a SOAP message?

• Sql server management studio reporting "The semaphore timeout period has expired."

  - by nis-simonsen

  On our development sql server, executing any query containing more than approximately 700 characters stalls for about 10 seconds and then reports the following error: Msg 121, Level 20, State 0, Line 0 A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.) for example, this query select * from FooTable where id = ' (.. and then 700 spaces ..) ' fails fails with the timeout error while this one select * from FooTable where id = ' (.. and then 600 spaces ..) ' fails with the expected Msg 8169, Level 16, State 2, Line 1 Conversion failed when converting from a character string to uniqueidentifier. - immediately. Indeed, throwing any query, including random garbage at our dev sql server exhibits this behaviour, while any other sql server I have available acts as expected, so I would think that the query never actually gets to parsing on the server. I'm at a loss here - any hints?

• Formatting numbers by tokens with php

  - by Adam D

  I'm looking for a way to format numbers using "tokens". This needs to be conditional (for the first few leading characters). Example: <?php $styles=array('04## ### ###','0# #### ####','13# ###','1800 ### ###'); format_number(0412345678); /*should return '0412 345 678'*/ format_number(0812345678); /*should return '08 1234 5678'*/ format_number(133622); /*should return '133 622'*/ format_number(1800123456); /*should return '1800 123 456'*/ ?> Incase you haven't guessed, my use of this is to format Australian phone numbers, dependent on their 'type'. I have a PHP function that does this, but it is ~114 lines and contains a lot of repeated code. Can anyone help?

• Is it possible to use JavaScript to break the HTML of a page?

  - by Karl Brown

  I've been asked at work whether it is possible to write, on purpose or by accident, JavaScript that will remove specific characters from a HTML document and thus break the HTML. An example would be adding some JavaScript that removes the < symbol in the page. I've tried searching online and I know JavaScript can replace strings, but my knowledge of the language is negligible. I've been asked to look into it as a way of hopefully addressing why a site I work on needs to have controls over who can add bespoke functionality to the page. I'm hoping it's not possible but would be grateful for the peace of mind!

• "Intercepting" user input into text box and removing it

  - by James P

  I have a text box that I would like to do some validation on. At the moment I have this code: function updateChanger() { // Validate input var likeMessage = validateInput($("#like").val()); alert(likeMessage); } function validateInput(input) { input = input.replace(/[^a-zA-Z0-9:\(\/\)\s\.,!~]/g, ""); return input; } This successfully trims out unwanted characters in the likeMessage variable, but the character still gets entered into the text box. I would like to stop that from happening. I know it will have something to do with $("#like").val() but the only thing I can think of is just chopping off the end character from the text box value, would this suffice? Thanks for any help!

• How to read the whole istream correctly?

  - by L.Lawliet

  Here is a simple code to print all characters of a txt file on screen: #include <iostream> #include <fstream> #include <string> using namespace std; int main() { int **i; int j,k; char a; ifstream test("test.txt", ios::binary); while((a=test.get())!=-1)//if I use "while(!test.eof())" here, how to avoid the output of the last character(-1) to std::cout, or any ostream objects? { putchar(a);//also change this to putchar(test.get()); } getchar(); } As I noted in the code, if I use "test.eof()" to judge the end of test.txt, I'll always get an extra blank at the end of the output. How to avoid it?

• How do I split up a long value (32 bits) into four char variables (8bits) using C?

  - by Jordan S

  I have a 32 bit long variable, CurrentPosition, that I want to split up into 4, 8bit characters. How would I do that most efficiently in C? I am working with an 8bit MCU, 8051 architectecture. unsigned long CurrentPosition = 7654321; unsigned char CP1 = 0; unsigned char CP2 = 0; unsigned char CP3 = 0; unsigned char CP4 = 0; // What do I do next? Should I just reference the starting address of CurrentPosition with a pointer and then add 8 two that address four times? It is little Endian. ALSO I want CurrentPosition to remain unchanged.

• What encoding to use for exporting to CSV?

  - by Michael Borgwardt

  I'm developing a java app that exports data to CSV files, intended to be opened in Excel by end users. We just noticed that the export function uses Java's platform default encoding. This causes umlaut characters to be lost and unit test to fail on the build server (which is configured to have US-ASCII as its platform default encoding exactly to catch such potential problems). The question is: which would be the best encoding to use? How does Excel determine what encoding to use? Does it use something platform-specific that presumably matches Java's platform default? I'm currently leaning towards hardcoding Cp1252 - that should cover the target machines (the deployment environment is actually specified) and would fix the test problem. From googling around, Excel does not seem to handle UTF-8 well, so that's out, and sticking to the platform default encoding would require some sort of workaround hack for the tests.

• How can I truncate the mangled C++ identifiers shown by GDB's disassemble command?

  - by Rhys Ulerich

  GDB's disassemble command is nice for short C identifiers, e.g. main. For long, mangled C++ identifiers the verbosity is overkill. For example, using icpc I see results like (gdb) disassemble 0x49de2f 0x49de5b Dump of assembler code from 0x49de2f to 0x49de5b: 0x000000000049de2f <_ZN5pecos8suzerain16fftw_multi_array6detail18c2c_buffer_processIPA2_dPKSt7complexIdEilNS2_26complex_copy_differentiateIS4_EEEEvT_T1_T2_T0_SD_SE_RKT3_+167>: mov 0x18(%rsp),%rsi Displays that long are annoying in the CLI. They make GDB's TUI assembly display all but useless. Is there a way to tell GDB to show a truncated identifier? Say clip all but 50 characters?

• regex: trim all strings directly preceeded by digit except if string belongs to predefined set of st

  - by Geert-Jan

  I've got addresses I need to clean up for matching purposes. Part of the process is trimming unwanted suffices from housenumbers, e.g: mainstreet 4a --> mainstreet 4. However I don't want: 618 5th Ave SW --> 618 5 Ave SW in other words there are some strings (for now: st, nd, rd, th) which I don't want to strip. What would be the best method of doing this (regex or otherwise) ? a wokring regex without the exceptions would be: a = a.replaceAll("(^| )([0-9]+)[a-z]+($| )","$1$2$3"); //replace 1a --> 1 I thought about first searching and substiting the special cases with special characters while keeping the references in a map, then do the above regex, and then doing the reverse substitute using the reference map, but I'm looking for a simpler solution. Thanks
