Hi,

Have been following this tutorial
http://msdn2.microsoft.com/en-us/library/bb332058.aspx on reading cell
values from Open Excel XML format. Which is great as i no longer need Excel
Interop.

However if I I add a Workbook (structure and windows) password the document
can no longer be unzipped (think read somethere it is now a OLE compounded
document)

So my question is how can i get the file back to a state where i can zip
back out the Excel XML files? I don't really want to have to open the Excel
Application via COM Interop.

All help much appreciated.

Thanks

Gary
