  • Sinatra / Rack fails with non-ascii characters in url

    - by Piotr Zolnierek
    I am getting Encoding::UndefinedConversionError at /find/Wroclaw "\xC5" from ASCII-8BIT to UTF-8 For some mysterious reason sinatra is passing the string as ASCII instead of UTF-8 as it should. I have found some kind of ugly workaround... I don't know why Rack assumes the encoding is ASCII-8BIT ... anyway, a way is to use string.force_encoding("UTF-8")... but doing this for all params is tedious

  • How to change default conjunction with Lucene MultiFieldQueryParser

    - by Luke H
    I have some code using Lucene that leaves the default conjunction operator as OR, and I want to change it to AND. Some of the code just uses a plain QueryParser, and that's fine - I can just call setDefaultOperator on those instances. Unfortunately, in one place the code uses a MultiFieldQueryParser, and calls the static "parse" method (taking String, String[], BooleanClause.Occur[], Analyzer), so it seems that setDefaultOperator can't help, because it's an instance method. Is there a way to keep using the same parser but have the default conjunction changed?

    - by Shaun
    I have a form with a cmdbutton that at the moment opens another form and shows all records for several types of PartitionStyles and TrimFinishs (486 at present), I need to be able to filter the second form to show only the TrimFinish I need.

  • How to remove list of words from strings

    - by zeljko
    What I would like to do (in Clojure): For example, I have a vector of words that need to be removed: (def forbidden-words [":)" "the" "." "," " " ...many more...]) ... and a vector of strings: (def strings ["the movie list" "this.is.a.string" "haha :)" ...many more...]) So, each forbidden word should be removed from each string, and the result, in this case, would be: ["movie list" "thisisastring" "haha"]. How to do this ?

The problem is when i use string.replace and look for @a , it also replaces @a1 but it should not. Help me with regex replace, please. Cheers

  • Java regex return after first match

    - by user216915
    hi how do i return after the first match of regular expression? (does the Matcher.find() method do that? ) say I have a string "abcdefgeee". I want to ask the regex engine stop finding immediately after it finds the first match of "e" for example. I am writing a method to return true/false if the pattern is found and i don't want to find the whole string for "e". (I am looking for a regex solution ) thanks

  • How efficient is Python substring extraction?

    - by Cameron
    I've got the entire contents of a text file (at least a few KB) in string myStr. Will the following code create a copy of the string (less the first character) in memory? myStr = myStr[1:] I'm hoping it just refers to a different location in the same internal buffer. If not, is there a more efficient way to do this? Thanks! Note: I'm using Python 2.5.

  • Can I make Axis2 generate a WSDL with 'unwrapped' types?

    - by Bedwyr Humphreys
    I'm trying to consume a hello world AXIS2 SOAP web service using a PHP client. The Java class is written in Netbeans and the AXIS2 aar file is generated using the Netbeans AXIS2 plugin. You've all seen it before but here's the java class: public class SOAPHello { public String sayHello(String username) { return "Hello, "+username; } } The wsdl genereated by AXIS2 seems to wrap all the parameters so that when I consume the service i have to use a crazy PHP script like this: $client = new SoapClient("http://myhost:8080/axis2/services/SOAPHello?wsdl"); $parameters["username"] = "Dave"; $response = $client->sayHello($parameters)->return; echo $response."!"; When all I really want to do is echo $client->sayHello("Dave")."!"; My question is two-fold: why is this happening? and what can I do to stop it? :) Here's are the types, message and porttype sections of the generated wsdl: <wsdl:types> <xs:schema attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="http://soap.axis2.myhost.co.uk"> <xs:element name="sayHello"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="username" nillable="true" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="sayHelloResponse"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="return" nillable="true" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> </wsdl:types> <wsdl:message name="sayHelloRequest"> <wsdl:part name="parameters" element="ns:sayHello"/> </wsdl:message> <wsdl:message name="sayHelloResponse"> <wsdl:part name="parameters" element="ns:sayHelloResponse"/> </wsdl:message> <wsdl:portType name="SOAPHelloPortType"> <wsdl:operation name="sayHello"> <wsdl:input message="ns:sayHelloRequest" wsaw:Action="urn:sayHello"/> <wsdl:output message="ns:sayHelloResponse" wsaw:Action="urn:sayHelloResponse"/> </wsdl:operation> </wsdl:portType>

  • Help with storing/accessing user access roles C# Winforms

    - by user222453
    Hello, firstly I would like to thank you in advance for any assistance provided. I am new to software development and have designed several Client/Server applications over the last 12 months or so, I am currently working on a project that involves a user logging in to gain access to the application and I am looking at the most efficient and "simple" method of storing the users permissions once logged in to the application which can be used throughout restricting access to certain tabs on the main form. I have created a static class called "User" detailed below: static class User { public static int _userID; public static string _moduleName; public static string _userName; public static object[] UserData(object[] _dataRow) { _userID = (int)_dataRow[0]; _userName = (string)_dataRow[1]; _moduleName = (string)_dataRow[2]; return _moduleName; } } When the user logs in and they have been authenticated, I wish to store the _moduleName objects in memory so I can control which tabs on the main form tab control they can access, for example; if the user has been assigned the following roles in the database: "Sales Ledger", "Purchase Ledger" they can only see the relevant tabs on the form, by way of using a Switch - Case block once the login form is hidden and the main form is instantiated. I can store the userID and userName variables in the main form once it loads by means of say for example: Here we process the login data from the user: DataAccess _dal = new DataAccess(); switch (_dal.ValidateLogin(txtUserName.Text, txtPassword.Text)) { case DataAccess.ValidationCode.ConnectionFailed: MessageBox.Show("Database Server Connection Failed!"); break; case DataAccess.ValidationCode .LoginFailed: MessageBox.Show("Login Failed!"); _dal.RecordLogin(out errMsg, txtUserName.Text, workstationID, false); break; case DataAccess.ValidationCode .LoginSucceeded: frmMain frmMain = new frmMain(); _dal.GetUserPrivList(out errMsg,2); //< here I access my DB and get the user permissions based on the current login. frmMain.Show(); this.Hide(); break; default: break; } private void frmMain_Load(object sender, EventArgs e) { int UserID = User._userID; } That works fine, however the _modules object contains mutiple permissions/roles depending on what has been set in the database, how can I store the multiple values and access them via a Switch-Case block? Thank you again in advance.
