Your function must be declared inside class such as

void __fastcall TForm1::MyBeforeEdit (TDataSet *DataSet){};

If you need an external function you should write something like:

class MyClass
{
 public:
  void __fastcall MyBeforeEdit(TDataSet *DataSet) {/*Your code here*/};
} MyVar;


__fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner)
{
 ADODataSet1->BeforeEdit = MyVar.MyBeforeEdit;
}
