delete the hyperlink linked to the organizational chart in excel using vba

hi
i am trying to remove hyperlinks that are linked to objects in the excel workbook using vb.
the code that i am using is as follows:

If wSheet.Hyperlinks(i).Type <> 0 Then
wSheet.Hyperlinks(i).Delete
ObjExcel.Save
hashyperlinks = True
End If

this code does not remove hyperlinks from the organizational charts, flow charts, cycle diagrams, etc. it just removes hyperlinks from the images
can some1 pls help.

thanks in advance
