Hi Aspose team.
I’m encountered a problem trying to open my presentation
file using Aspose.Slides v5.2.0.0 library.
You can find PowerPoint file in the attachment. It was made
in PowerPoint 2010 but saved as 2003 format. PowerPoint itself found no issues
in the file.
When I’m executing the code below it falls into exception “Index
was outside the bounds of the array.”
///
/// PowerPoint data processor for Aspose library
/// Perform reading/writing operations with
Excel.
///
/// Array of bytes with PowerPoint file
body
public
PowerPointAsposeProcessor(byte[] fileData)
{
try
{
Stream
stream = new MemoryStream();
stream.Write(fileData, 0, fileData.Length);
var
loadOptions = new LoadOptions(LoadFormat.Ppt);
_presentation = new Presentation(stream, loadOptions);
stream.Dispose();
}
catch
(Exception err)
{
LOG.Error(err);
}
}
Could you please investigate the reason of this issue and
provide an update (if necessary)?
Thank you
Hi Andrew,
I have observed the code snippet. You are missing following statement in your code snippet. Please add the statement after you have written the byte array in stream and before you are accessing the stream in presentation.
stream.Write(fileData, 0, fileData.Length);
stream.Position = 0;
Thanks and Regards,
Wow, my bad. Thank you for immediate response. Everything works fine now.
PS: strange, but Aspose.Cells works fine without setting position, that’s why I’ve missed it in my code.
In any case thank you for clarification.
