I have tried it. From main program, one button call a procedure in a
DLL with a form. Inside this procedure I code this:
Application.Initialize;
Application.CreateForm(TForm2, Form2);
Form2.ShowModal();
Is this Ok?
I don't think so. The main thread of the main application (may same be
in Pascal or some other language) already attaches to the external GUI
and I don't suppose it's allowed or makes sense to have the same thread
create another GUI hook.
It might be possible to do
GUI2Thread.Execute;
begin
Application.Initialize;
Application.CreateForm(TForm2, Form2);
Application.Run;
...
in a thread.
(In the main program itself this is not allowed, as the LCL GUI
environment is not reentrant, but I understand that the DLL uses it's
own LCL GUI environment.)
Good luck (I never tested this) :) !
