Re: [libreoffice-users] Experimental macro features: How to determine object types?

Aaaaaaaa! Sorry, Stephan Bergmann! I accidentally replied to you, while my
intention was to reply to the list.
Here it is, this time to the list, and this time with further comments at
the end:

I looked a little more into it and I finally got it to work. I'm not sure I
still understand this, but this works:

*Private Function ItemFound(sItem As string, _ oRange As
com.sun.star.sheet.XSheetCellRange) As Boolean Dim oDescriptor As
*End Function*

So the answer to my question seems to be
”com.sun.star.util.XReplaceDescriptor”. Exactly why is a little blurry to
me at the moment.

Kind regards
