I want to load a protected workbook for readonly access. The spreadsheet I have has a password for "Protect Structure and Windows" set. This does not disallow the file from being opened, just from workbooks being added to the file. When I try to load the workbook, I get the error listed below. Is there a way around this? Will this be fixed in a later release? Attached is the file used(with the extension changed from xls to txt to allow uploading).
{"Attempted to read past the end of the stream."}

You may want to consult with OS2 because they're able to support encryption for PDF files in their PDF4NET product.
As Dimi explained above, we cannot support this for legal reasons.
Is there a way to save password protected spreadsheets?
It seems like you posted the same question on this thread. Please refer to it for responses.
hi,
I have downloaded the lastest excel dll (Infragistics4.Documents.Excel.v11.2 - Version 11.2.20112.1010) from Infragistic webiste but I am still getting the same error message for the one of the file.
May I know the reason or root cause of this issue?
Thanks,
