A lower level class creates objects of type DataPacket when new packets arrive. I then want to pass the object into the callback function as a constant reference so not to copy the entire object and restrict the user from changing the original object. What's going on here? How can I pass DataPacket into f_Callback as a const reference? c++ c++11 const pass-by-reference share|improve this question edited Jul 28 '14 at 4:11 user2864740 35.2k43778 asked Jul 18 '14 at 1:03 KKlouzal 13112 marked as duplicate by Praetorianc++ Users with the c++ badge can single-handedly close c++ questions as duplicates and reopen them as needed.

The error: Code: error C2662: 'Item::GetName' : cannot convert 'this' pointer from 'const Item' to 'Item &' error c2662 cannot My class definition: Code: class Inventory { public: Inventory(vector ITEMLIST): itemList(ITEMLIST) {} inline void ListItems(); private: vector itemList; }; The class member function that the error is occurring in (error line in red): Code: inline void Inventory::ListItems() { if(itemList.empty()) cout << "\n\nYou have no items."; else { vector::const_iterator iter = itemList.begin(); for(iter; iter != itemList.end(); ++iter) { cout << "\n\n"; cout << iter->GetName(); } } } And the class (Item) member function that the iter is trying to access: Code: string GetName() { return name; } I can't get around this error.. it's beyond my knowledge I think. I've tried and I'm seeking helppppppp. If I'm missing anything out let me know! Good judgment is gained from experience. Experience is gained from bad judgment.

'this' pointer from 'const class' to 'class & Look at following sample class myClass { public: int get(); private: int m_member; }; int myClass::get() { return m_member; } int main() { const myClass own; own.get(); // compiling error return 0; } A const object try to call non-const function, it is risk to change value of const object. For the reason, we have to define myClass::get() to be a const function so that we could call the function by a const object. int myClass::get() const Or we also can define own to be a non-const object. myClass own; Reference: http://hi.baidu.com/idealsoft/blog/item/629ae129a7f14afb99250af4.html http://forums.codeguru.com/archive/index.php/t-416873.html 張貼者： Senerata 於 下午3:27 以電子郵件傳送這篇文章BlogThis！分享至 Twitter分享至 Facebook分享到 Pinterest 反應： 沒有留言: 張貼留言 較新的文章 較舊的文章 首頁 訂閱： 張貼留言 (Atom) 標籤 .Net (9) Android Develop (26) Article Links (1) Berkeley DB (1) Chromium (1) CPP (25) Data Format (3) GTK (1) HTML (6) Java (1) Linux (9) MFC (2) QT (3) Quiz (15) SCM (10) SQL (3) System (1) Tools (7) VS .Net CF (12) WebKit (24) Win API (7) 追蹤者 網誌存檔 ► 2015 (5) ► 四月 (1) ► 三月 (1) ► 二月 (3) ► 2014 (11) ► 九月 (2) ► 七月 (1) ► 五月 (1) ► 三月 (3) ► 二月 (3) ► 一月 (1) ► 2013 (21) ► 十二月 (3) ► 十一月 (1) ► 十月 (3) ► 六月 (1) ► 五月 (5) ► 三月 (6) ► 一月 (2) ▼ 2012 (68) ► 十二月 (3) ► 十一月 (5) ► 十月 (11) ► 九月 (9) ► 八月 (6) ► 七月 (1) ▼ 五月 (11) Watch Virtual / Physical Memory Usage Watch Process Memory Usage [C++] error C2662 cannot convert 'this' pointer fr..
