Subj : MDIChild Stack overflow To : borland.public.cpp.borlandcpp From : Charlie Page Date : Thu Jul 24 2003 05:40 pm Whenever I use an int in the ctor for a MDI form I get a stack overflow. The program makes an endless amount of TMDIForm forms. Does anyone know why this is? I am using BCB 5. works: TMDIForm : TMDIChild { public: // User declarations __fastcall TMDIForm(TComponent* Owner); } fails: TMDIForm : TMDIChild { public: // User declarations __fastcall TMDIForm(TComponent* Owner, int MyInt); } Thanks, Charlie .
