问题 I want to make a game of BlackJack. I want to make a vector of images and when I press a button a new image shows up(need 2 or 3 images). After that I want to delete all of them in another button press. I try to declare an vector in main class(Unit1.h): class TForm1 : public TForm{ ... public: TImage* Images[]; And in Form1(Unit1.cpp): void __fastcall TForm1::Button1Click(TObject *Sender) { // i=1 is global Images[i] =new TImage(this); Images[i]->Parent=this; Images[i]->Picture->Bitmap->.../

问题 I would like to use TComInterface to replace raw pointer. My current code is: { TComInterface<IStoreNamespace> pStore; if (SUCCEEDED(CoCreateInstance(CLSID_StoreNamespace, NULL, CLSCTX_INPROC_SERVER, IID_IStoreNamespace, (LPVOID*)&pStore))) { if (SUCCEEDED(pStore->Initialize(Form1->Handle, 1))) { //pStore->CallOtherMethods... } } // Release()'d automatically? } If I understood correctly this overwrites the pStore pointer with new pointer so it doesn't call pStore->Release(); automatically

问题 Specific question How to create an array of buttons on Borland C++ Builder and work with it? I'm using Borland C++ Builder 6 and Borland Developer Studio 2006 (Turbo C++ 2006).

问题 Got Link error (Fatal: Access violation. Link terminated) in Borland 6.0. How do I know what is the cause of it ? Is there any output file that I can open and get more informative message ? 回答1: You should be able to use the command line that gets passed to the linker to determine which .obj files are being passed to the linker. You can then include/exclude files to see when the error occurs. A number of linker problems have been fixed since BCB6, you may want to try the linker from a demo of
