global

问题 Is there any way to set global memory byte alignment for all data structures in JNA library (*.dll Java wrapper)? Sometimes I have to determine correct alignment by trial and error during implementation and currently I'm doing this in very clumsy way - I'm setting data alignment (super(ALIGN_NONE)) in each and every structure (a lot of structures in separate files). edit: The best way to solve my problem was to extend Structure: public abstract class StructureAligned extends Structure {

问题 If I remember correctly, functions must be a member of a class in the CLR world, and yet global functions are possible in C++/CLI. Does this mean that these global functions are part of a hidden "global" class of some sort? If so, how would one go about getting its type, for reflection purposes? 回答1: Yes, .NET metadata supports global functions and variables. Called the "Global Class" in CLR source code, its name is <Module> . Using C# vernacular, it is internal , abstract and sealed to

问题 Why is the following code not working? According to this article the usage of global should be correct: http://technet.microsoft.com/en-us/library/ff730957.aspx Function global:writeLog { param($logType, $logString, $logFile) $fileStream = New-Object IO.FileStream $logFile ,'Append','Write','Read' $streamWriter = New-Object System.IO.StreamWriter $fileStream $time = get-date -Format "hh:mm:ss" $streamWriter.writeLine("[${time}][$logType] ${logString}") $streamWriter.close() } $temp = {

问题 I am trying to make global structure, which will be seen from any part of the source code. I need it for my big Qt project, where some global variables needed. Here it is: 3 files (global.h, dialog.h & main.cpp). For compilation I use Visual Studio (Visual C++). global.h #ifndef GLOBAL_H_ #define GLOBAL_H_ typedef struct TNumber { int g_nNumber; } TNum; TNum Num; #endif dialog.h #ifndef DIALOG_H_ #define DIALOG_H_ #include <iostream> #include "global.h" using namespace std; class ClassB {

问题 I'm having some trouble with installing composer globally. I install composer into my 'C:\wamp\bin\php\php5.4.12' - directory (I'm using WAMP) and make a project in 'C:\wamp\www\project' using the command: php composer.phar create-project . The problem is that I can only use the php composer.phar command when I'm in the directory where I installed it (bin\php\php5.4.12), this directory is already in my path variables. Their is also a composer.bath file including in that directory: "@ECHO OFF"

问题 In a previous Q&A (How do I define friends in global namespace within another C++ namespace?), the solution was given for making a friend function definition within a namespace that refers to a function in the global namespace. I have the same question for classes . class CBaseSD; namespace cb { class CBase { friend class ::CBaseSD; // <-- this does not work!? private: int m_type; public: CBase(int t) : m_type(t) {}; }; }; // namespace cb class CBaseSD { private: cb::CBase* m_base; public:

问题 I'm trying to use a variable / list in a function that is defined in another function without making it global. Here is my code: def hi(): hello = [1,2,3] print("hello") def bye(hello): print(hello) hi() bye(hello) At the moment I am getting the error that "hello" in "bye(hello)" is not defined. How can I resolve this? 回答1: if you don't want to use a global variable, your best option is just to call bye(hello) from within hi() . def hi(): hello = [1,2,3] print("hello") bye(hello) def bye

问题 How do I count the number of visitors for website in asp.net c#? I am using the code below: in global.asax page <%@ Application Language="C#" %> void Application_Start(object sender, EventArgs e) { // Code that runs on application startup Application["NoOfVisitors"] = 0; } void Session_Start(object sender, EventArgs e) { // Code that runs when a new session is started Application.Lock(); Application["NoOfVisitors"] = (int)Application["NoOfVisitors"] + 1; Application.UnLock(); } in .aspx page

问题 I have the following script myclass.php <?php $myarray = array('firstval','secondval'); class littleclass { private $myvalue; public function __construct() { $myvalue = "INIT!"; } public function setvalue() { $myvalue = $myarray[0]; //ERROR: $myarray does not exist inside the class } } ?> Is there a way to make $myarray available inside the littleclass, through simple declaration? I don't want to pass it as a parameter to the constructor if that was possible. Additionally, I hope that you

问题 I have a .NET form, and a native code in my Visual Studio. The problem is: I can't declare a global instance of my .NET form in my native code, like this: Editor^ maineditor; It gives me this problem: error C3145: 'EditorEntry' : global or static variable may not have managed type 'Cube3D::Editor ^' 回答1: Instead of using a global static try making it a static method in a container type ref class ManagedGlobals { public: static Editor^ maineditor = nullptr; }; 回答2: wrap the handle with a
