(1) [Serializable()] //Set this attribute to all the classes that you define to be serialized
    public class Serializeclass : ISerializable
(2)     Stream stream = File.Open("Serializeclass", FileMode.Create);
            BinaryFormatter bformatter = new BinaryFormatter();
            bformatter.Serialize(stream, sc);
            stream.Close();
(3) stream = File.Open("Serializeclass", FileMode.Open);
            bformatter = new BinaryFormatter();
 物件可以serialized自己，但是無法de-serialized自己(除非透過一個空殼子)

與系統核心(尤其是有硬體有關的或是與作業系統的程式)還是用native codeing比較好。
但是如果要放在網路上的應用，還是考量一下系統架構跟程式維護的便利性吧。

比較 managed & unmanaged code的執行效能
results shows that the optimization switches in managed C++ and C# have relatively small effects, and that there is only a 2% difference between managed and unmanaged code. Significantly, C# code is as good, or better than managed C++ or C++/CLI which means that your choice to use a managed version of C++ should be based on the language features rather than a perceived idea that C++ will produce 'more optimized code'.

=======================
動態指派函數去執行(這也是後來event hanlder都需要用此)
You can use them to replace switch/if-statements, to realize your own late-binding or to implement callbacks.
The calling convention tells the compiler things like how to pass the arguments or how to generate the name of
a function. Some examples for other calling conventions are __stdcall, __pascal and __fastcall. The calling
convention belongs to a function's signature: Thus functions and function pointers with different calling
convention are incompatible with each other! For Borland and Microsoft compilers you specify a specific
calling convention between the return type and the function's or function pointer's name.
=======================
結論就是
Callback 是pointer to function一種實作(透過pointer to function，可以達到late binding)，
但是這個實在windows有用到event 發出時給系統處理，因此callback function位置與變數需要被全域化
(也可以理解成被OS觸發執行，而非程式設計者)，這樣系統才不會被整個callback function要處理的內容給hold住。
Windows的event透過pointer to funtion實作的好處
在message queue中，只要透過message 對應到的function名稱，就可以執行。
而callback這個keywork，在windows程式設計中，如果用了這個keyword，系統會給函數一個全域的id(這是交給系統處理的),
這樣可以方便系統管理(這也意味者，如果有其他介面要跟call back function溝通，就需要有好的架構設計)。

Hmm..找到一段bug…在VC++可以過->離開後new_num就是39119，但在BCB離開後，這個會變成任意數字，不過也因為這樣剛好找到
這個地方的new_num應該改成i
//Find Bugs...
for(i=0;i
{
if(gene[new_num].pix_inten_recor!=NULL)
free(gene[new_num].pix_inten_recor);
gene[new_num].pix_inten_recor=NULL;
if(gene[new_num].periphery_x!=NULL)
free(gene[new_num].periphery_x);
gene[new_num].periphery_x=NULL;
if(gene[new_num].periphery_y!=NULL)
free(gene[new_num].periphery_y);
gene[new_num].periphery_y=NULL;
}

A:這次的版本，你到底找到什麼bug了?為什麼memory leak的問題都沒有了
B:我也不知道，我只是每次把free之後，就把pointer設為NULL，每次calloc之前，都會先check是否為NULL
<看來不同compiler之間還是有差異的>

請問下面程式有幾處會出現問題!?
====================
 int i;
 double *dia;
 dia=(double *)calloc(gene[0].periphery_num,sizeof(double));
 for(i=0;i
 {
  dia[i]= (gene[0].center_x-gene[0].periphery_x[i])*(gene[0].center_x-gene[0].periphery_x[i])
                                     +
          (gene[0].center_y-gene[0].periphery_y[i])*(gene[0].center_y-gene[0].periphery_y[i]);
  dia[i]=pow(dia[i],0.5)*10;
  if(dia[i]>FC_parmeter.r_radius || dia[i]
                       return 0;
              
 
 }
 return 1;
        free(dia);
