rpo/Roman,
          I saw your answer for MDI Child forms in dlls
(Q.10181952) and reckon it was a great answer. I just have a small follow up question for you. If I wanted to access the MDI Child form from a unit that I do some processing in
how can it be done. In your Dll code you create the forms via the functions and that works fine. I am just unable to access the form from anywhere else ie another unit or another form. I have tried to include the unit in the uses clause to no avail. I am wondering is this an inherent problem or can it be overcome.

Regards,

 WESTY :)

Westy, this is simple (it is a pseudocode):

unit CommonMDIChild;

uses Forms,MDIChildLibInt;

interface

var
  Child : TForm;

procedure MyProc;
begin
  Child:=GetNewChild(MyOwner);
end;

end;

Now You can include the CommonMDIChild unit in uses clause and You will have access to Child form.

You need separate variable for each form You get from DLL.

Roman,
      I figured it was something like that. For the moment I used procedures rather than functions to initialise the forms.

 ie MyForm := TMyForm.Create(Application)

rather than  Result := TMyForm.Create(Application) and this enabled me to access the forms everywhere.

I appreciate you getting back to me so quickly. I would of e-mailed you a question but couldn't find it at expert-exchange.

Thanks again,

WESTY :)
