C++中COM组件初始化方法实例分析

CoInitialize(NULL);//初始化COM套件CoUninitialize();//释放COM套件

static bool isCoInitialize = false; //是否是自己进行的初始化int WINAPI DllEntryPoint(HINSTANCE hinst, unsigned long reason, void* lpReserved){  if(reason==DLL_PROCESS_ATTACH)  {    if(ConInitialize(NULL) == S_OK) isCoInitialize = true;  }  if(reason==DLL_PROCESS_DETACH)  {    if(isCoInitialize) CoUninitialize();    //是自己初始化的才释放，否则由其他初始化的地方自行释放，    //防止错误的释放导致别的调用者失败  }  return 1;}
