问题 I need to have this node in my SOAP Request (using 1.1): <CredentialsHeader xmlns="http://www.url.com/Services/P24ListingService11" <EMail>ricky@email.net</EMail> <Password>password</Password> </CredentialsHeader> So I have the following PHP: $client = new SoapClient("https://exdev.www.example.com/Services/example.asmx?WSDL", array( "trace" => 1, "exceptions" => 0, "cache_wsdl" => 0, 'soap_version' => SOAP_1_1 ) ); $CredentialObject = new SoapVar(array('EMail' => 'ricky@email.net', 'Password'

问题 Suppose I have a utility library ( other ) containing a subroutine ( sort_it ) which I want to use to return arbitrarily sorted data. It's probably more complicated than this, but this illustrates the key concepts: #!/usr/local/bin/perl use strict; package other; sub sort_it { my($data, $sort_function) = @_; return([sort $sort_function @$data]); } Now let's use it in another package. package main; use Data::Dumper; my($data) = [ {'animal' => 'bird', 'legs' => 2}, {'animal' => 'black widow',

问题 I love the "Resolve" feature in visual studio. Typical scenario: Type in Debug Type . Notice that no intellisense appears Right-click Select Resolve Choose using System.Diagnostics or System.Diagnostics.Debug Beautiful. Use it all the time. Extension method scenario: Type in var maxNumber = new int[] {1, 2, 3, 4} Type . Notice that intellisense brings up array methods but no LINQ extension methods Manually type Max() Right-click Max() No Resolve to be found Right click on int[] Still no

问题 I'm working on a project and I'm really trying to write object-oriented JavaScript code. I have just started reading Douglas Crockford's JavaScript: The Good Parts and I'm quickly beginning to realize that writing Java-esque OOP in JavaScript will be a difficult task. Thus far, I've written something like the following... // index.html $(document).ready(function() { $().SetUpElements(); }); // this is in a different js file $.fn.SetUpElements = function() { // do stuff here $().UpdateElement(

问题 Similar questions have been raised multiple times, but I'm focussing on the namespace and pointer issues. MyClass.h namespace foo { class MyClass { MyClass(); }; QDataStream &operator<<(QDataStream &out, const MyClass & myObj); QDataStream &operator>>(QDataStream &in, MyClass &myObj); } // namespace foo Q_DECLARE_METATYPE(foo::MyClass) // #1 Q_DECLARE_METATYPE(foo::MyClass*) // #2 fooMyClass.cpp (so many permutations): MyClass::MyClass() { qRegisterMetaType<MyClass>("MyClass"); // #3

问题 I am a Java developer, totally new to C#. I am currently writing a DLL for distribution across my organization. It is a very simple library containing a couple of classes and I do not see any real use in putting all of them into some namespace just for the sake of it. Do I really have to use a namespace? If so, why? Is it some kind of a best practice? 回答1: Do you need one? No. Should you have one? Yes. It'll help prevent clashes with identically named classes in other namespaces without

问题 I'm having issues with Doxygen recognizing namespaces and modules. I believe the issue surrounds whether to place the \addtogroup within the namespace or outside the namespace. Example 1, outside the namespace: /*! * \addtogroup Records * @{ */ //! Generic record interfaces and implementations namespace Records { //! Describes the record interface class Interface; } // End namespace Records /*! @} End of Doxygen Groups*/ Example 2 - within namespace //! Generic record interfaces and

问题 I think I hvae a fundamental misunderstanding of namespace and/or static variable. But I have tried this test code (typed by hand, forgive typos) test.h: namespace test{ static int testNum=5; void setNum(int value); } main.cpp: #include <test.h> int test::setNum(int value){ testNum=value; } int main(){ test::setNum(9); cout<<test::testNum; } when I run this I get the value 5, not 9 as I would have expected. It seems almost as if I have two instances of the testNum variable, but that seems to
