Well,
as you can see from the massive issues via this forum, the OWC documentation is very poor
1st possibility is to post a Q in this forum and hope for the best
2nd is MSDN - If you have a spare time..
3rd - if you have OWC license, you can check for a reasonably help file that normaly is in
"C:\Program Files\Common Files\Microsoft Shared\Web Components\10\1033\OWCVBA10.CHM
other than that , try google
HTH.
