[Lazarus] New Excel Interface Component

[Thierry Coq]

Yes, definitively,

I've checked, this code seems to be currently geared to use DISPID 
interfaces. This works in Delphi, but not in FPC for the time being.

For example, the following code:
   fDocument := fDesktop.loadComponentFromURL('file:///'+ 
StringReplace(FileName, '\', '/', [rfIgnoreCase, rfReplaceAll]) , 
'_blank', 0, wProperties);

declares fDocument as an OleVariant. The author hopefully expects FPC to 
understand how to go and fetch "loadComponentFromURL". It ain't gonna 
work ;-).

It should be done this way:
   var fDocument : IDispatch;
   ...
   fDocument.InvokeDispatch( DISPID_LOADCOMPONENTFROMURL, ...);
