...会感到Swift的似曾相识。Swift采用了Objective-C的命名参数和动态对象模型。提供了对Cocoa框架和mix-and-match的互操作性。基于这些基础，Swift引入了很多新功能和结合面向过程和面向对象的功能。
Swift对新的程序员也是友好的。他是...

How do you loop through currently loaded assemblies?
...
Please note that both methods only list dll's that are actually used. Obviously it makes no sense to have references in solutions that are not used, but this might be confusing when someone is trying to speculatively scan through ALL assemblies. All assemblies migh...
[精华] VC中BSTR、Char和CString类型的转换 - C/C++ - 清泛网 - 专注C/C++及内核技术
...况，利于对问题的深入理解。例如我们现在用到的ICF底层库就有很多类似下面的函数：
void CTestDlg::GetString(BSTR* state)
{
_bstr_t m_state(L"cc");
*state = m_state.copy();
}
其中_bstr_t的copy函数其实调用了SysAllocStringByteLen，所以...

快速重传机制
于是，TCP引入了一种叫Fast Retransmit 的算法，不以时间驱动，而以数据驱动重传。也就是说，如果，包没有连续到达，就ack最后那个...

The following code is reflected out of the System.Runtime.Caching DLL, for the CacheMemoryMonitor class (there is a similar class that monitors physical memory and deals with the other setting, but this is the more important one):

How do you create a static class in C++?
..., but still visible. This is not as important as it seems, but still, in a DLL, showing a symbol that should be private to the DLL in an exported header could be awkward... In the namespace, the myGlobal exists only in the CPP file (you can even go farther and make it static). That variable doesn't ...
Making code internal but available for unit testing from other projects
...private members of a class, you shouldn't be testing internal classes of a DLL. Those classes are implementation details of some publicly accessible class, and therefore should be well exercised through other unit tests.
The idea is that you only want to test the behavior of a class because if you ...
Why is the Java main method static?
...ng is a couple of Java Native Interface (JNI) calls. These calls load the DLL that is really the JVM (that's right - java.exe is NOT the JVM). JNI is the tool that we use when we have to bridge the virtual machine world, and the world of C, C++, etc... The reverse is also true - it is not possibl...
