1.what is Event in C#       simplely speaking,Event  in C# is that as one instance does one behaviour, it will receive the message and then react with the message.2.Event Happening&Re-acting Mechanism3.how to declare a Event    i.first declare a

Any data which is declared private inside a class is not accessible from outside the class. A function which is not a member or an external class can never access such private data. But there may be some cases, where a programmer will need need

本文將引導你在Linux作業系統下利用Axis C++來構建Web服務，同時將介紹如何開發和部署可在Axis C++下使用的Web服務。眾所周知，Axis是一個非常出名的Web服務架構軟體，它有Java和C++兩個版本。關於Java版我已經寫了兩篇文章來介紹它，分別是《應用AXIS開始Web Service之旅》以及《AXIS實現Web

在做Clucene與lucene產生的Index檔案相互相容時，遇到了編碼轉換問題。它們的相容性對於非英文的編碼可能都會存在這樣的問題，經過跟蹤clucene程式，發現它用的是unicode編碼方式儲蓄，因此，要先把字串或檔案轉換成unicode編碼，然後再進行其它處理。轉換的具體代碼如下(Linux與vc6.0測試通過)：#ifndef _UNIXstatic inline int codepage(const char* code_page){    return 936;//"GBK"}#

Java / C++ Socket ClassIf you need to do socket communication between a Java and/or C++ programs, you've come to the right place.  I've developed a fairly basic class that can be used to communicate between Java applications and C++ programs via a

泛型簡介    泛型是C#2.0最為強大的特點之一。泛型使得我們定義型別安全（type-safe)的資料結構。因為我們可以重用資料處理的演算法而無需關注資料的特定類型，從而提高開發效率和代碼品質。從觀念上講，泛型類似欲C++中的模板，但是他們的實現和功能卻有著很大的不同。泛型問題描述    假設一種常用的資料結構，例如stack,他提供的經典method比如push和pop。

    abstract class and interface in C# look like much, but sometimes they get the similiar use. However, there are still much differences between them. here we go.    抽象類別和介面初看上去很象，但是還是有很多區別的。   a) Interface Grammar介面文法  

1.basic concepts    function pointer in C/C++ is just like delegate in C#. we can use function pointer to point to a specific function, and then use function pointer to invoke the specified function.    eg.    int max(int a,int b)    {    return

1.    In C programming, the normal use of #define is to declare an constant vairiable. But it's been replaced by const.C: #define X 100   ----> C++: const int x=100;2.    #define can also define Macro with parameters. But its functionality can

        在C#中，no matter what language the code is programmed with, 所有的source code都被編譯成為IL,然後再CLR（類似於JAVA的虛擬機器）上運行。當然，CLR會負責把IL轉化為machine language.       但是，不管我們運用那種語言編程，都會存在一些最為常用的資料類型，我們稱之為primitive type，比如int, char,float,double等等。實際上這些primitive
