Link in Borland C++ Builder 6

[royal084]

i need to make 4 different forms in 1 project in borland C++ Builder.forms r different but there is some similar tasks of them.so i made a common base form with similar tasks and all codes of similar tasks r same.now from the base form develop 4 other form.
example:
suppose one base form "Base"->with 3 common button save new Close.

now need to make another 4 forms including these 3 task.so save this "BASE" form in four Different names and also "Add this file to the project".and develop these 4 forms seperately.all codes of similar tasks r in base form.
Problem is that in BASE form Button i write the code;but when run the other forms and click the buton.it doesn't close.
how to link between base and other forms
Base form
#include <vcl.h>
#pragma hdrstop

#include "BaseMD.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TBaseMDForm *BaseMDForm;
//---------------------------------------------------------------------------
__fastcall TBaseMDForm::TBaseMDForm(TComponent* Owner)
: TForm(Owner)
{
}
//---------------------------------------------------------------------------
void __fastcall TBaseMDForm::ExitClick(TObject *Sender)
{
Close();
}
//---------------------------------------------------------------------------
One other form:

#include <vcl.h>
#pragma hdrstop

#include "PurOrder.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TPurOrderForm *PurOrderForm;
//---------------------------------------------------------------------------
__fastcall TPurOrderForm::TPurOrderForm(TComponent* Owner)
: TForm(Owner)
{
}
//---------------------------------------------------------------------------

Well, your is-a relationship is sound, inheirtance is resonable. However, your code snippets are incomplete to make any sence of them as you have only included the source files. Please include the header files, where the definition of the TBaseMDForm and the TPurOrderForm are located. I know nothing about Borland's C++ Builder, but I could determine what is going on with the definition of the classes.

BTW, please enclose your code snippets in [code] [/code] tags. It helps breaking things up to make it easier to read. Thanks.
