Add Forms from another project in Borland C++ - project

Question

I'm currently working on a project using Borland C++, I have two Forms so far but each one in an independent Project, I wish to join these two project into one project so I can switch between the Forms.
I want to have only one executable file (for security purposes), I tried reading some pdfs about borland c++, also tried googling it, but no luck.
if there's a way to do so, I wish you could guide me or give me some hints.
Note: I'm using Borland C++ Builder 6, under Windows 8.1.

Answer 1

I am used to BDS2006 so for newer IDE/Compilers it can be different
1.form copy
has .h,.cpp,*.dfm files
copy them to target project directory
2.open target project in IDE
3.add forms to project
find add to project in IDE main menu (I think it is in Project tag)
then select *.dfm files of your new forms click add or OK ...
4.Open target project source code (*.cpp)
should look like this:
//$$---- EXE CPP ----
//---------------------------------------------------------------------------
#include <vcl.h>
#pragma hdrstop
//---------------------------------------------------------------------------
//*** here you have line for each form type and its name in forms menu
USEFORM("win_view.cpp", win_view);
USEFORM("win_main.cpp", win_main);
USEFORM("win_editor\win_editor_setup.cpp", win_EditorSetup);
USEFORM("win_editor\win_editor.cpp", win_editor);
USEFORM("win_editor\win_editor_find.cpp", win_EditorFind);
//---------------------------------------------------------------------------
WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
try
{
Application->Initialize();
//*** here create form for each static form you want
//*** dynamic windows (created in runtime are not here !!!
Application->CreateForm(__classid(Twin_main), &win_main);
//*** here load cross references to forms if needed
Application->Run();
}
catch (Exception &exception)
{
Application->ShowException(&exception);
}
catch (...)
{
try
{
throw Exception("");
}
catch (Exception &exception)
{
Application->ShowException(&exception);
}
}
return 0;
}
//---------------------------------------------------------------------------
5.dynamic forms
add #include of *.h for all dynamic/used inside form files to main form cpp file
this makes them accessible from main form
now you can crete / destroy windows
should look like this:
//---------------------------------------------------------------------------
#include <vcl.h>
#pragma hdrstop
#include "win_main.h"
//*** add the dynamic/used forms *.h files
#include "win_view.h"
#include "win_editor\win_editor.h"
//---------------------------------------------------------------------------
//*** add pointer to dynamic forms
Twin_view *win_view=NULL;
//---------------------------------------------------------------------------
void __fastcall Twin_main::some_event(...)
{
win_view=new Twin_view(win_main);
if (win_view)
{
win_view->OnResize(win_view);
win_view->_can_close=false;
}
}
//---------------------------------------------------------------------------
void __fastcall Twin_main::FormDestroy(TObject *Sender)
{
//*** destroy form before exiting also can call ->Close() and wait few [ms] before
if (win_view) { delete win_view; win_view=NULL; }
}
//-------------------------------------------------------------------
you can also move the form pointers to owner form class to make it more objective c++ like
and allow to make multiple originaly main forms in future (in another project later)
6.static used forms
just include *.cpp file instead of *.h
the pointer to these forms are directly in *.cpp files (at the start)
[notes]
if your forms have some global variables
then you can not use more then 1 form of that type
also the global variable names have to be different between used forms
do not change namespace for them it will make VCL crazy
