  • Prevent python from printing newline

    - by wrongusername
    I have this code in Python inputted = input("Enter in something: ") print("Input is {0}, including the return".format(inputted)) that outputs Enter in something: something Input is something , including the newline I am not sure what is happening; if I use variables that don't depend on user input, I do not get the newline after formatting with the variable. I suspect Python might be taking in the newline as input when I hit return. How can I make it so that the input does not include any newlines so that I may compare it to other strings/characters? (e.g. something == 'a')

  • Using singleton instead of a global static instance

    - by Farstucker
    I ran into a problem today and a friend recommended I use a global static instance or more elegantly a singleton pattern. I spent a few hours reading about singletons but a few things still escape me. Background: What Im trying to accomplish is creating an instance of an API and use this one instance in all my classes (as opposed to making a new connection, etc). There seems to be about 100 ways of creating a singleton but with some help from yoda I found some thread safe examples. ..so given the following code: public sealed class Singleton { public static Singleton Instance { get; private set; } private Singleton() { APIClass api = new APIClass(); //Can this be done? } static Singleton() { Instance = new Singleton(); } } How/Where would you instantiate the this new class and how should it be called from a separate class? EDIT: I realize the Singleton class can be called with something like Singleton obj1 = Singleton.Instance(); but would I be able to access the methods within the APIs Class (ie. obj1.Start)? (not that I need to, just asking) EDIT #2: I might have been a bit premature in checking the answer but I do have one small thing that is still causing me problems. The API is launching just fine, unfortunately Im able to launch two instances? New Code public sealed class SingletonAPI { public static SingletonAPI Instance { get; private set; } private SingletonAPI() {} static SingletonAPI() { Instance = new SingletonAPI(); } // API method: public void Start() { API myAPI = new API();} } but if I try to do something like this... SingletonAPI api = SingletonAPI.Instance; api.Start(); SingletonAPI api2 = SingletonAPI.Instance; // This was just for testing. api2.Start(); I get an error saying that I cannot start more than one instance.

  • Localization — how to check that Filename1 and Filename2 are the same

    - by modosansreves
    I want to know that Filename1, provided by the user is the same as stored in DB (Filename2). I was about to use string.Equals(Filename1, Filename2, StringComparison.CurrentCultureIgnoreCase) but then I doubted whether I should use StringComparison.InvariantCultureIgnoreCase. Obviously, I need to do this the same way OS does, or use appropriate API. In some cultures, AFAIK, characters (e.g. vocals) may change if the next one is Capitalized. As I primarily target English-speaking market, I'd like my software to work well throughout the world.

  • wxruby - Set max length of ComboBox

    - by Jonas Söderström
    Is is possible to set the Max length of a ComboBox in wxruby? I have looked in the documentation but find nothing http://wxruby.rubyforge.org/doc/combobox.html But if i do my_combobox.methods.sort I get set_max_size and set_min_size in the list. But When I call it my_combobox.set_max_length(100) I only get undefined method 'set_max_length' for #<Wx::ComboBox:0x4d4a914> I've also tried to call it as a private method def my_combobox.max(i) set_max_length(i) end my_combobox.max(100) But with the same result. The issue I want to avoid is that if somebody pastes 6000+ characters in my Combobox the text becomes white.

  • Table comment length in mysql

    - by azerole
    According to MySQL manual, table comments are limited to 60 characters. I'm designing the schema in MySQL Workbench, which does not enforce this limit, so I end up with writing more than 60 symbols quite often, and this causes the SQL script to fail. To tell the truth I would be quite happy with table comments being internal to my schema (i.e. not exported to the actual database), but Workbench doesn't allow this either. Hence my question: is there a way to increase maximum length of table comment in MySQL to 255?

  • Set focus and carret position in textarea according to mouse position, as if user had clicked

    - by JeanHuguesRobert
    Once a page with a textarea is loaded, I want some textarea to have the focus immediatly if the mouse cursor is inside that textarea. This is the easy part because a onmousehover handler can set the focus. Now, how to I also set the position of the caret? I would like the caret to be where it would be if the user had clicked using the mouse to set the focus/caret. The basic use case is : User clicks on a link and waits (mouse barely moves) A page is delivered, it contains a big textarea only, full of text User types using keyboard Characters are inserted right below the mouse cursor Today the user has to wait until the caret is visible (at the top left of the textarea) and then click to move the caret before typing. Thanks!

  • Django, ModelForms, User and UserProfile - not hashing password

    - by IvanBernat
    I'm trying to setup a User - UserProfile relationship, display the form and save the data. When submitted, the data is saved, except the password field doesn't get hashed.

  • Code Golf Christmas Edition: How to print out a Christmas tree of height N

    - by TheSoftwareJedi
    Given a number N, how can I print out a Christmas tree of height N using the least number of code characters? N is assumed constrained to a min val of 3, and a max val of 30 (bounds and error checking are not necessary). N is given as the one and only command line argument to your program or script. All languages appreciated, if you see a language already implemented and you can make it shorter, edit if possible - comment otherwise and hope someone cleans up the mess. Include newlines and whitespace for clarity, but don't include them in the character count. A Christmas tree is generated as such, with its "trunk" consisting of only a centered "*" N = 3: * *** ***** * N = 4: * *** ***** ******* * N = 5: * *** ***** ******* ********* * N defines the height of the branches not including the one line trunk. Merry Christmas SO!

  • Determining whether values can potentially match a regular expression, given more input

    - by Andreas Grech
    I am currently writing an application in JavaScript where I'm matching input to regular expressions, but I also need to find a way how to match strings to parts of the regular expressions. For example: var invalid = "x", potentially = "g", valid = "ggg", gReg = /^ggg$/; gReg.test(invalid); //returns false (correct) gReg.test(valid); //returns true (correct) Now I need to find a way to somehow determine that the value of the potentially variable doesn't exactly match the /^ggg$/ expression, BUT with more input, it potentially can! So for example in this case, the potentially variable is g, but if two more g's are appended to it, it will match the regular expression /^ggg$/ But in the case of invalid, it can never match the /^ggg$/ expression, no matter how many characters you append to it. So how can I determine if a string has or doesn't have potential to match a particular regular expression?

  • How can I loop through every letter in MS Word using VBA?

    - by Behrooz Karjooravary
    I have about 100 ms word documents which include transliteration of foreign names. The author of these docs used a special font called e2 which has about a dozen special transliteration characters (all of which are available in ms sans serif font). I would like to loop through every letter of the document and whenever the font = e2 i would like to loop through the dozen letters (it's easy to guess what they are) and replace them with a Microsoft Sans Serif equivalent. But I can't figure out how you can loop though letters. Is that doable like looping through cells in an excel spread sheet?

  • How do I make a textbox that only accepts numbers?

    - by Mykroft
    I have a windows forms app with a textbox control that I want to only accept integer values. In the past I've done this kind of validation by overloading the KeyPress event and just removing characters which didn't fit the specification. I've looked at the MaskedTextBox control but I'd like a more general solution that could work with perhaps a regular expression, or depend on the values of other controls. Ideally this would behave such that pressing a non numeric character would either produce no result or immediately provide the user with feedback about the invalid character.

  • Remove newlines from MarkupBuilder result

    Is there a way to control groovy's MarkupBuilder's output and filter out the newline characters? I have code like below: import groovy.xml.MarkupBuilder def writer = new StringWriter() def xml = new MarkupBuilder(writer) xml.basket(){ fruit (type:"apple", 1) fruit (type:"orange", 2) } which invariably outputs: <basket> <fruit type='apple'>1</fruit> <fruit type='orange'>2</fruit> </basket> I'd really like it in a single line: <basket><fruit type='apple'>1</fruit><fruit type='orange'>2</fruit></basket>

  • How can I use TMask when the mask contains "["?

    - by Lobuno
    I have been experimenting with TMask in Delphi 2010 and it seems to work as expected except in one situation: when the mask name contains [ or ] the mask always seem to return false. For example: var MaskObj : TMask; begin MaskObj:= TMask.Create('c:\[test]\*'); try Result:= MaskObj.Matches('c:\[test]\text'); finally FreeAndNil(MaskObj); end; end; returns false. ... Yes, [ and ] are legal characters in file name. So if I want to exclude for example all files in c:[test]*, what could I do here? My only solution is to do a StringReplace if [ is detected, but this will be slow for a large number of files: if (pos('[', Mask)>0) then begin mask:= ReplaceString(Mask, '[','_', etc... // and do the same for the file name--- end; Is there any other approach?

  • Repair bad character due to encoding problem

    - by remi bourgarel
    Hi all, Recently we had an encoding problem in our system : If we had the string "æ" in our db ,it became "æ" on our web pages. Now this problem is solved, but the problem is that now we have a lot of "æ" in our database : users didn't see and validate pre-filled form with these characters. I found that If you read in utf 8 C3A6 you'll get "æ", if you read it in ascii you'll get "æ". It's strange because if I execute "select convert(varbinary(40),N'æ'),convert(varbinary(40),'æ')" I don't have the same result... Do you have any idea on how I can fix my database (ie change all "æ" to "æ") ? thx

  • How big can a user agent string get?

    - by Josh
    If you were going to store a user agent in a database, how large would you accomdate for? I found this technet article which recommends keeping UA under 200. It doesn't look like this is defined in the HTTP specification at least not that I found. My UA is already 149 characters, and it seems like each version of .net will be adding to it. I know I can parse the string out and break it down but I'd rather not. EDIT Based on this Blog IE9 will be changing to send the short UA string. This is a good change.

  • Flash AS3: crop TextField content off at X lines, add '...' at the end

    - by matt lohkamp
    There's only room for three lines of text in the interface, but the content is external and variable, and if it ends up taking up more than three lines, there needs to be some sort of 'view all' button functionality. I can kind of think about what that function needs to look like, but I'm not quite sure what the best way to do it in AS3 would be. Something like (in pseudo code): function cropText(source:TextField, length:int, append:String):TextField{ if(source.lineCount > length){ source.text = // magic function that retuns the first length lines, // minus append.length characters, with the append value tacked onto the end } return source; } ... right? How would you fill in the missing bit?

  • Algorithm for measuring distance between disordered sequences of strings

    - by Kinopiko
    The Levenshtein distance gives us a way to calculate the distance between two similar strings in terms of disordered individual characters: quick brown fox quikc brown fax The Levenshtein distance = 3. What is a similar algorithm for the distance between two strings with similar subsequences? For example, in quickbrownfox brownquickfox the Levenshtein distance is 10, but this takes no account of the fact that the strings have two similar subsequences, which makes them more "similar" than completely disordered words like quickbrownfox qburiocwknfox and yet this completely disordered version has a Levenshtein distance of eight. What distance measures exist which take the length of subsequences into account, without assuming that the subsequences can be easily broken into distinct words?

  • Howto format a date as localized Short MonthDay string

    - by Wouter
    I would like to format a DateTime to a string containing the month name abbreviated and the date for use in axislabels in a graph. The default DateTime format strings do not contain abbreviated month. I guess there is no standard but I could take a substring of the first 3 characters of the month name and replace this into the MonthDay format. The reason I would use MonthDay is that the ordering of month and date is locale dependent. Does anyone have a better idea? http://msdn.microsoft.com/en-us/library/az4se3k1.aspx#MonthDay

  • A regex to match a comma that isn't surrounded by quotes.

    - by Rayne
    I'm using Clojure, so this is in the context of Java regexes. Here is an example string: "{:a "ab,cd, efg", :b "ab,def, egf,", :c "Conjecture"}" The important bits are the commas after each string. I'd like to be able to replace them with newline characters with Java's replaceAll method. A regex that will match any comma that is not surrounded by quotes will do. If I'm not coming across well, please ask and I'll be happily to clarify anything. edit: sorry for the confusion in the title. I haven't been awake very long. String: {:a "ab, cd efg",} <-- In this example, the comma at the end would be matched, but the ones inside the quote would not.

  • Regex Problem in PHP

    - by Chris
    I'm attempting to utilize the following Regex pattern: $regex = '/Name: [a-zA-Z ]*] [0-9]/'; When testing it in Rubular, it works fine, but when using PHP the expression never returns true, even when it should. Incidentally, if I remove the "[0-9]" part, it works fine. Is there some difference in PHP's regex syntax that I'm overlooking? Edit: I'm looking for the characters "Name:" then a name containing any number of letters or spaces, then a "]", then a space, then a single number. So "Name: Chris] 5" would return true and "Name: Chris] [lorem ipsum]" should return false. I also tried escaping the second bracket "\[" but this did not fix the problem.
