最近看了Everett N.McKay & Mike Woodring 的classical Debugging Windows Programs談談一些收穫，以共大家分享. sharing with everybody

1.試著處理可能在程式裡出錯的建構函式．

Try to disposal construct function which was likely to slip a cog in a programme.

---------

CMyObject::CMyObject(const CString &resourse1,const CString &resourse2)

{

  //Do safe initialization first

  m_pRourse1=0;

  m_pRourse2=0;

}

//now do initialization that can fail

try{

  m_pRourse1=CreateResourse(resourse1);

   m_pRourse2=CreateResourse(resourse2);

}

catch(...){

//  must clean up here,since destructor won`t be called.

delete m_pResourse1;

delete m_pResourse2;

m_pResourse1=0;

m_pResourse2=0;

throw;

}

 2.保證解構函式中的異常在解構函式內部得到處理．

Make sure the exception in destruct function be resolved in iteself.

---------

the same as the construct.(omit)
