Setting unit scope in XE2

Further to my previous question, I had an error when trying to call MessageDlg()

[DCC Error] MainForm.pas(54): E2003 Undeclared identifier: 'mtError'

So I pulled up help and found that mtError is declared in Dialogs.

I opened Project/Options/Unit scope names and added Dialogs.

And I still get the same error.

I can has halpz?

Add Vcl instead of Dialogs in Project->Options->Unit scope names.

This was answered in the second link I posted to your last question (the subtopic Fully Qualified Names Must Include the Unit Scope Name.

There's something strange about your project, though. If I create a new VCL project (File->New->VCL Forms Application), and then add the following code, it compiles fine with no changes to default compiler settings.

procedure TForm1.FormCreate(Sender: TObject);
begin
  MessageDlg('Test message', mtError, [mbOK], 0);
end;
