• 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?

• BCB: how to get the (approximate) width of a character in a given TFont?

  - by mawg

  It's a TMemo, not that that should make any difference. Googling suggests that I can use Canvas->TextWidth() but those are Delphi examples and BCB doesn't seem to offer this property. I really want something analogous to memo->Font->Height for width. I realize that not all fonts are fixed width, so a good estimate will do. All that I need is to take the width of a TMemo in pixels and make a reasonable guess at how many characters of the current font it will hold. Of course, if I really want to be lazy, I can just google for the average height/width ratio, since height is known. Remember, an approximation is good enough for me if it is tricky to get exact. http://www.plainlanguagenetwork.org/type/utbo211.htm says, " A width to height ratio of 3:5 (0.6) is recommended for most applications"

• Accented character regex

  - by user314573

  I'm trying to create a regex that will look for french words whether a user specifies the accented characters or not. So if the the user has searched for "déclaré" but types in declare instead I would like to be able to match the text still. I'm having difficulty making this more dynamic so that it can be matched on any french word... Closest example from another user from a different post was: d[eèéê]cl[aàáâ]r[eèéê] Is it even possible to write a regex for something like this? Any advice would be much appreciated.

• 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

• Data loss when converting from QString to QByteArray

  - by SleepyCod

  I'm using QPlainTextEdit as an HTML editor, saving the data through an HTTP post with QNetworkAccessManager. I experience data loss when using HTML special characters such as & (ampersand) I'm building a POST request with a QByteArray (as mentioned in the docs). QByteArray postData; QMapIterator<QString, QString> i(params); while(i.hasNext()) { i.next(); postData .append(i.key().toUtf8()) .append("=") .append(i.value().toUtf8()) .append("&"); } postData.remove(postData.length()-1, 1); //Do request QNetworkRequest postRequest = QNetworkRequest(res); oManager.post(postRequest, postData);

• idiomatic way to take groups of n items from a list in Python?

  - by Wang

  Given a list A = [1 2 3 4 5 6] Is there any idiomatic (Pythonic) way to iterate over it as though it were B = [(1, 2) (3, 4) (5, 6)] other than indexing? That feels like a holdover from C: for a1,a2 in [ (A[i], A[i+1]) for i in range(0, len(A), 2) ]: I can't help but feel there should be some clever hack using itertools or slicing or something. (Of course, two at a time is just an example; I'd like a solution that works for any n.) Edit: related http://stackoverflow.com/questions/1162592/iterate-over-a-string-2-or-n-characters-at-a-time-in-python but even the cleanest solution (accepted, using zip) doesn't generalize well to higher n without a list comprehension and *-notation.

• 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!

• Best way to get a reasonably random key for MYSQL records

  - by Steve N

  Hi there, I need to generate a reasonably random unique key for a table. It should be something like a GUID for MYSQL. I've tried UUID, but it looks like only the first few characters are actually random- the rest are the same every time I insert them. Essentially, it is desirable for this key field to be very difficult to guess, even if you already have one known value in the column. What is the best way to do this, and how should I set up the field data type to store the value efficiently? Thank you, Steve

• problems with matlab wavrecord and wavread

  - by user504363

  Hi all I have a problem in matlab I want to record a speech for 2 seconds then read the recorded sound and plot it I use the code FS = 8000; new_wav = wavrecord(2*FS,FS,'int16'); x = wavread(new_wav); plot(x); but the error appears ??? Error using ==> fileparts at 20 Input must be a row vector of characters. Error in ==> wavread>open_wav at 193 [pat,nam,ext] = fileparts(file); Error in ==> wavread at 65 [fid,msg] = open_wav(file); Error in ==> test at 2 x = wavread(new_wav); I plotted correctly recorded sound files, but when I want to record new one through matlab I get this errors. I tried many ways by changing FS and 'int16' but nothing happens. thanks

• How can I detect if a string contains punctuation marks at the end?

  - by Sheehan Alam

  Lets assume I have the string: "Hello I like your shoes #today...!" I am tokenizing the string by spaces: return [string componentsSeparatedByString:@" "]; So my array contains: Hello I like your shoes #today...! I want to focus on "#today...!" any word that has a # in the prefix I am changing the font color. How can I make sure that only "#today" has its font color changed? I would basically like to figure out if a word has a punctuation mark at the end, and change the color for characters before the punctuation mark.

• 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.

• 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?

• 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.

• jquery plugins for truncating long text string by container width/height

  - by ShiVik

  Hello all As the title says, I want to truncate user-input text string based on the width and height of a designated container. My specification is to truncate the string, display some message like Read More at the end and when user clicks on it, the text slides down. UPDATE: Ah! Forgot one thing. It should handle multi-byte characters as well. Can somebody throw some light on what options do I have? jQuery plugins or some nifty jquery snippet? Thanks and Regards

• How to deal with the new line character in the Silverlight TextBox

  - by Ian Oakes

  When using a multi-line TextBox (AcceptsReturn="True") in Silverlight, line feeds are recorded as \r rather than \r\n. This is causing problems when the data is persisted and later exported to another format to be read by a Windows application. I was thinking of using a regular expression to replace any single \r characters with a \r\n, but I suck at regex's and couldn't get it to work. Because there may be a mixture of line endings just blindy replacing all \r with \r\n doesn't cut it. So two questions really... If regex is the way to go what's the correct pattern? Is there a way to get Silverlight to respect it's own Environment.NewLine character in TextBox's and have it insert \r\n rather just a single \r?

• The best way to ensure only 1 copy of bash script is running?

  - by depesz

  What is the simplest/best way to ensure only 1 copy of given script is running - assuming it's bash on linux? At the moment I'm doing: ps -C script.name.sh > /dev/null 2>&1 || ./script.name.sh but it has several issues: it puts the check outside of script it doesn't let me run the same script from separate accounts - which I would like sometimes. -C checks only first 14 characters of process name Of course I can write my own pidfile handling, but I sense that there should be some simple way to do it.

• Proper Regex to find and replace escaped UTF-8 strings

  - by Piet Binnenbocht

  (edited) I am reading a JSON file that includes some UTF-8 characters that are encoded like this: "\uf36b". I am trying to write a RegExp to convert this to an HTML entity that looks like "&#x1F36B;". This displays the character correctly in my html page. I haven't been able to correctly display the character that should be associated with "\uf36b", especially when in a longer sentence that also includes other text. How can I write a regexp that replaces strings like "\uf4d6" and "\uf36b" but leaves other text alone? Example: var str = "I need \uf36b #chocolate"; This should be converted to: I need &#x1F36B; #chocolate;

• 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.

• 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.

• iPhone simulator app crashes when appending a string

  - by Franklyn Weber

  Hi, I'm a complete novice, so I'm probably missing something really easy, but I can't get my string appending to work. I add the 3rd character to typedDigit & it crashes - the method is called fine and typedDigit will get to 2 characters long. I think everything is declared properly in the header file. Code is - -(IBAction)digitPressed:(UIButton *)sender { NSString *digit = [[sender titleLabel] text]; // in this case, "0" - "9" if (userIsInMiddleOfTyping) { // typedDigit is already at least 1 character long typedDigit = [typedDigit stringByAppendingString:digit]; } else { // first character of typedDigit typedDigit = digit; userIsInMiddleOfTyping = YES; } } Many 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?

• Send and receive Array as GET/POST using querystring

  I've got the following code, but it doesn't seem to work: var post_req = { array: [ [ { param1: 'something', param2: 123 } ], [ ], [ ], [ { param2: 'something', param4: 1234, param1: 'hello' } ] ] }; var data_send = querystring.stringify(post_req); var request = client.request('POST', '/', headers); request.end(data_send); and if( req.method == 'POST' ) { req.addListener('data', function(chunk) { POST = querystring.parse(chunk); console.log(POST); } } I end up with 5 sub-arrays, corresponding to the 5 parameters in the objects but with extra '][' characters in their names: { array: [ { '][param1': 'something' } , { '][param2': '123' } , { '][param2': 'something' } , { '][param4': '1234' } , { '][param1': 'hello' } ] }
