I have been using FindComponent for a quite long time without problems.
My Cinedisk application wouldn't work without that. Smile

procedure TForm1.Button1Click(Sender: TObject);
var
   TestComponent: TLabel;
begin
   TestComponent := TLabel(FindComponent('Label1'));
   ShowMessage(TestComponent.caption);
end;

Just try it. It works!

<< Question: Is it possible to find a tab in an Application by its name?  >>

Do you mean "tab" or "page" ?  Tabs are contained within a TPage component instance and don't have a "name", so you would have to look for the name of the TPage, not the tab.

@Uli, yes, it works. However, I am trying to find a component on another form.

@ Tim, yes I mean page.

Basically, pages are created dynamically at Run-time. They are named and based on this name I need to see if the page exists, and then 'jump' to it by showing it to the user.

When I do this, I keep a record of the components created so that I
don't have to spend time finding them later. A TObjectList is ideal,
with a matching TStringList if you need to reference by text. One day
we may get a list with both string and object like the Delphi
TStringList's Object property, but that would probably be better done
as a dictionary or something anyway, and if one is getting fancy, the
better option still is to create an object to represent the data, and
have the reference string and the UI component stored as properties,
and then put that in a TObjectList. Wrap that in a controller and we
reach the ideal.

Sorry, got a bit carried away there, but that's what I have found so
good about EWB - there is no limit to doing things properly. I have
been so happy using it to write my current application as I just write
nice OOP code and it handles it without problem.

Yes, you can find a TPage instance by name on another form using FindComponent, provided that the form was created with the global Application instance as its owner.

In case it's not clear, you would use something like this:

Application.FindComponent('MyPage',True);
