Function OpenFromStream( _
   ByVal stream As Stream _
) As IWorkbook

IWorkbook OpenFromStream( 
   Stream stream
)

Parameters

stream

The stream containing the workbook to open.

Return Value

The stream must consist solely of a file which SpreadsheetGear is able to read. If the stream is not seekable, this method will copy the stream to a MemoryStream and read the workbook from the MemoryStream.

The various workbook settings which make a workbook read-only in an end user workbookSet have no affect at this level. These settings are available as IWorkbook properties.
