The dll contains a form, and there is an ActiveX control in the form. Why does it always say that CoInitialize is not av

I have a dll file that contains a form and an ActiveX control inside the form. I want to call a function in the dll in another project without displaying the form in the dll. The system always reports an error: CoInitialize Who can tell me why? How should it be achieved? The following is a function in the form that my Dll contains:
procedure Info;
  var
    Form1: TForm1;
  Begin
      Form1: = TForm1.Create (nil);
      ShowMessage ('hello3');
      Form1.Free;
  End; I tried it, other space is OK, ActiveX control is not enough, master click it! !! !!

Write the following code at the end of your form pas file:

initialization
  CoInitialize (nil);
finalization
  CoUnInitialize;

end.

var
  Form1: TForm1;
Begin
  CoInitialize (Nil);
  Form1: = TForm1.Create (nil);
  ShowMessage ('hello3');
  Form1.Free;
  CoUninitialize;
End;

The control of the com object requires CoInitialize and CoUninitialize. . . .

COINNITIALIZE is called every time a method of the COM object is called
