What wrong I did:
1. in Win95, click at file c:\myfile.txt, Notepad actived with myfile.txt appeared. That means .txt is registed and the automation interface is OK.
2. excuted code
   dim act as object
   set act = getobject("c:\myfile.txt")
and got "not find file..." error.

I doubt it is doable to do OLE Automation with Notepad.  I tried this, and it didn't work, but when I replaced it with a word document, it worked fine.  Why do you want to do automation on a text file?

The fact notepad opens myfile.txt doesn't means it has ole interface registered. The myfile is passed as a command line parameter to notepad, and it opens it. You can do the same thing using the Command$ function

Hi Anthonyc,

Thank you for your two comments.
As you know now, I just want to learn getobject() since it is under Activex which looks like something new.
My PC hasn't got MS Word but when I click at the .doc file the Wodpad actived...As MikeP said that doesn't mean ole interface registered (Why not say "automation interface registered"?).

Cheers.

Wordpad is not OLE automation compatible.. that's why it doesn't work.

Hi Experts,

I have check the OLE automation by puting an OLE control into the form and looking at the property box. There are some classes included in the box: PBrush, Paint.Pecture and others. Hence, I quess those must be registed automation interfaces! So, I tried:
dim act as object
set act = createobject("Paint.Picture")  'or ("PBrush")
but still got error message: Object required:-(
