TXWordDlg

has anybody used TXWordDlg (from XWordDialog_TLB) ??

can i get to the word _Document interface ??

i have tried...
var DocObj: _Document;
...
    if XWordDlg.ControlInterface.QueryInterface(IID__Document, DocObj) =
S_OK then
    begin
        // do stuff
    end;

with no luck, any ideas ?

regards,
Adrian.
