Syntax for Assignment of delphi enumerated set types in C+

In general replace member access “.” With “->” and casting with pointer notation.  Search the web for further assistance. For instance,  take a look at the following link for assistance on set notation.

For instance, the following delphi code can be translated to C++

procedure TSearchDemoForm.wwSearchBox1PerformCustomSearch(Sender: TObject;
  DataSet: TDataSet; SearchField, SearchValue: string; var Found,
  DoDefault: Boolean);
begin
  TwwSearchBox(Sender).FilterDialogNeeded;
  TwwFilterDialog(TwwSearchBox(Sender).FilterDialog).OnFilterPropertyOptions:= [fdClearWhenCloseDataSet]; 
End;

Here is the equivalent code in C++.

void __fastcall TSearchDemoForm::wwSearchBox1PerformCustomSearch(
TObject *Sender, TDataSet *DataSet, UnicodeString SearchField, 
UnicodeString SearchValue, bool &Found, bool &DoDefault)
{
  TwwSearchBox * sb = (TwwSearchBox *)Sender;
  sb->FilterDialogNeeded();
  TwwFilterDialog * fd = (TwwFilterDialog *)sb->FilterDialog;
  fd->OnFilterPropertyOptions = TwwOnFilterPropertyOptions() << 
     TwwOnFilterPropertyOption::fdClearWhenCloseDataSet;
}
