Finding an object in a report by type

I see from the manual that you can find an object in a report by name, i.e.

TfrxMemoView * Memo = dynamic_cast <TfrxMemoView *> (frxReport1->FindObject("Memo1"));

This does not really help if you are parsing a user designed report and they have assigned some arbitrary name to a component.

However I have a custom component that can be used in a report and I just want to know if this component has been used in a particular report. So I am after something along the line sof

TfrxMemoView * Memo = dynamic_cast <TfrxMemoView *> (frxReport1->FindObjectType(TfrxMemoView));

Can this be done?

    I think of such a method:
    - Give your component a special Type,
    - Search through ALL objects of the report,
    - Check if any of its object is of Type you've created for your component.

    I thought iterating through all components would do the trick but I couldn't see how to do that in the manual - i'll have another look.

    Yes, that needs an iterating!
    You can search for knowledge: in manuals, in this forum, through tickets support, and ... hours of testing by yourself.
    No way of those above gives one the whole solution :-(

    My suggestion for an iterating (I did for FastReport script, didn't try to see that in compiler): 
    for i:=0 to (Report.AllObjects.Count - 1) do with TObject( Report.AllObjects.Items[i]) do
  if Classname = 'TfrxMemoView' 
    then ShowMessage( TfrxMemoView( Report.AllObjects.Items[i]).Name + #13 +
                      TfrxMemoView( Report.AllObjects.Items[i]).Text)
    else ShowMessage( TfrxComponent( Report.AllObjects.Items[i]).Name);
