Embedding multiple Excel Sheets in an anchored Window

[Aviv]

Following June2nd's advice, I learned how to place an anchor window in
Visio:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvisio00/html/visanchorwindows.asp

Now I have to show in that window some Excel tables that are spread in
different documents.

How can I embed multiple Excel Sheets in an anchored Window?

On tool box for userform, press right button, a menu for other controls.
Select "Microsoft Office SpreadSheet 11.0", attatch it on user form twice
for 2 excel sheets.
