When I try to assign myEventHandler to myClass

问题 I have some simple C++ code which won't be compiled by the Clang based C++11 compiler bccaarm of C++ Builder 10.1 Berlin. This is the code: TComponent* Comp = new TComponent(this); std::vector<TComponent*> Comps; Comps.push_back(Comp); And this is the error: [bccaarm error] stl_iterator.h(963): rvalue reference to type 'value_type' (aka 'System: classes::TComponent * __strong') can not be bound to lvalue of type '__borland_class * isTObj __strong' (aka 'System::Classes::TComponent * __strong'

问题 I'm using C++Builder 10.1 Berlin to write a simple WebSocket server application, which listens on a port for some commands sent from a web browser, like Google Chrome. On my Form, I have a TMemo, TButton and TIdHTTPServer, and I have this code: void __fastcall TForm1::Button1Click(TObject *Sender) { IdHTTPServer1->Bindings->DefaultPort = 55555; IdHTTPServer1->Active = true; } void __fastcall TForm1::IdHTTPServer1Connect(TIdContext *AContext) { Memo1->Lines->Add(AContext->Binding->PeerIP);
