  • [PowerShell] Input encoding

    - by Andy
    Hi! I need to get output of native application under PowerShell. The problem is, output is encoded with UTF-8 (no BOM), which PowerShell does not recognize and just converts those funky UTF chars directly into Unicode. I've found PowerShell has $OutputEncoding variable, but it does not seem to affect input data. Good ol' iconv is of no help either, since this unnecessary UTF8-as-if-ASCII = Unicode conversion takes place before the next pipeline member acquires data.

  • Different ways of accessing configuration parameters from a JAX-WS service

    - by ecerulm
    As far as I know I can access the web.xml <context-param>s by making my class implement ServletContextListener and use the ServletContext.getInitParam(String) to read them, but it´s cumbersome as only one instance of the class will receive the contextInitialized(ServletContextEvent sce) call, so I need to make the ServletContext an static member of the class. What other ways exist of setting conf params at deployment time and what are the recommended ones?

  • Uses for the capacity value of a string

    - by dreamlax
    In the C++ Standard Library, std::string has a public member function capacity() which returns the size of the internal allocated storage, a value greater than or equal to the number of characters in the string (according to here). What can this value be used for? Does it have something to do with custom allocators?

  • Who use class variables in SOAP calls with Savon?

    - by Steffen Roller
    I'm writing a little client using Ruby and Savon. The interface changed significantly from version 0.7 to 0.8.x. All my calls don't work anymore :-(. How can I pass on a local member variable. Please see the example, @userName and @userPassword are not defined within the block. begin @response = @authentication_svc.request :wsdl, "AuthenticateUser" do http.headers["SOAPAction"] = "AuthenticateUser" soap.body = "#{@userName}#{@passwd}" end rescue Savon::SOAP::Fault = e @last_soap_error = e.message end

  • Endianness conversion and g++ warnings

    - by SuperBloup
    I've got the following C++ code : template <int isBigEndian, typename val> struct EndiannessConv { inline static val fromLittleEndianToHost( val v ) { union { val outVal __attribute__ ((used)); uint8_t bytes[ sizeof( val ) ] __attribute__ ((used)); } ; outVal = v; std::reverse( &bytes[0], &bytes[ sizeof(val) ] ); return outVal; } inline static void convertArray( val v[], uint32_t size ) { // TODO : find a way to map the array for (uint32_t i = 0; i < size; i++) for (uint32_t i = 0; i < size; i++) v[i] = fromLittleEndianToHost( v[i] ); } }; Which work and has been tested (without the used attributes). When compiling I obtain the following errors from g++ (version 4.4.1) || g++ -Wall -Wextra -O3 -o t t.cc || t.cc: In static member function 'static val EndiannessConv<isBigEndian, val>::fromLittleEndianToHost(val)': t.cc|98| warning: 'used' attribute ignored t.cc|99| warning: 'used' attribute ignored || t.cc: In static member function 'static val EndiannessConv<isBigEndian, val>::fromLittleEndianToHost(val) [with int isBigEndian = 1, val = double]': t.cc|148| instantiated from here t.cc|100| warning: unused variable 'outVal' t.cc|100| warning: unused variable 'bytes' I've tried to use the following code : template <int size, typename valType> struct EndianInverser { /* should not compile */ }; template <typename valType> struct EndianInverser<4, valType> { static inline valType reverseEndianness( const valType &val ) { uint32_t castedVal = *reinterpret_cast<const uint32_t*>( &val ); castedVal = (castedVal & 0x000000FF << (3 * 8)) | (castedVal & 0x0000FF00 << (1 * 8)) | (castedVal & 0x00FF0000 >> (1 * 8)) | (castedVal & 0xFF000000 >> (3 * 8)); return *reinterpret_cast<valType*>( &castedVal ); } }; but it break when enabling optimizations due to the type punning. So, why does my used attribute got ignored? Is there a workaround to convert endianness (I rely on the enum to avoid type punning) in templates?

  • Can anyone help with this Magento error?

    - by Duane
    Fatal error: Call to a member function getArea() on a non-object in {directory}/includes/src/Mage_Core_Model_App_Area.php on line 155 Cropped up when I installed an extension that I wrote on a clean install of Magento. When ported to the dev server it took it down and I cant seem to find where it has originated. Disabling the extension changes nothing. Along with clearing the cache and all the regular Magento hiccups. I've ensured that file permissions are correct to the best of my knowledge.

  • How to access a field's value in an object using reflection

    - by kentcdodds
    My Question: How to overcome an IllegalAccessException to access the value of a an object's field using reflection. Expansion: I'm trying to learn about reflection to make some of my projects more generic. I'm running into an IllegalAccessException when trying to call field.getValue(object) to get the value of that field in that object. I can get the name and type just fine. If I change the declaration from private to public then this works fine. But in an effort to follow the "rules" of encapsulation I don't want to do this. Any help would be greatly appreciated! Thanks! My Code: package main; import java.lang.reflect.Field; public class Tester { public static void main(String args[]) throws Exception { new Tester().reflectionTest(); } public void reflectionTest() throws Exception { Person person = new Person("John Doe", "555-123-4567", "Rover"); Field[] fields = person.getClass().getDeclaredFields(); for (Field field : fields) { System.out.println("Field Name: " + field.getName()); System.out.println("Field Type: " + field.getType()); System.out.println("Field Value: " + field.get(person)); //The line above throws: Exception in thread "main" java.lang.IllegalAccessException: Class main.Tester can not access a member of class main.Tester$Person with modifiers "private final" } } public class Person { private final String name; private final String phoneNumber; private final String dogsName; public Person(String name, String phoneNumber, String dogsName) { this.name = name; this.phoneNumber = phoneNumber; this.dogsName = dogsName; } } } The Output: run: Field Name: name Field Type: class java.lang.String Exception in thread "main" java.lang.IllegalAccessException: Class main.Tester can not access a member of class main.Tester$Person with modifiers "private final" at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:95) at java.lang.reflect.AccessibleObject.slowCheckMemberAccess(AccessibleObject.java:261) at java.lang.reflect.AccessibleObject.checkAccess(AccessibleObject.java:253) at java.lang.reflect.Field.doSecurityCheck(Field.java:983) at java.lang.reflect.Field.getFieldAccessor(Field.java:927) at java.lang.reflect.Field.get(Field.java:372) at main.Tester.reflectionTest(Tester.java:17) at main.Tester.main(Tester.java:8) Java Result: 1 BUILD SUCCESSFUL (total time: 0 seconds)

  • protected internal

    - by adfs
    The C# Language Reference on MSDN defines that protected internal as "Access is limited to the current assembly or types derived from the containing class". But from the semantic point of protected internal" sounds to me like both protected and internal which means the member will accessible only to those derived classes with in the same assembly. Is there any access modified that has a meaning to the same effect?

What causes this? Also, is it possible to add .pdb files to a project's references? Thanks

    - by pollux
    Hi I'm working on some code where I have a Time object with a member time. Time.time gives me the time since my application started in seconds (float value).

  • C# CodeDom - making project's forms accessible for scripts.

    - by michal
    Hi, I'm learning CodeDom scripting, I started with http://www.c-sharpcorner.com/uploadfile/mgold/codedomcalculator08082005003253am/codedomcalculator.aspx Now I'd like to allow script modify the project's form (for learning purposes only). I suppose I need to create new field for a class I'm generating which refers "this". However I have no idea how can I set a reference for script-accessible object ... ? Or can I directly publish some class member (like "this" or "button1") to a CodeDom script structure?

    I have to make an application where a "sender" can send a message to a group of people and to a location.
