Hi, I am using Aspose Slides to identify which PPT files users are attempting to upload whihc are Office 97 or before.
These old files cause an error when atempting to open them
I'm using vb.net here is the code
Dim pres As Presentation = New Presentation("MyFile.ptt")
CATCH EX AS EXCEPTION
The file has errored because its a out of date ppt, but I cant delete it because Aspose is locking it.
H ow do I unlock the file so I can delete it?
How do I attempt identify if my ppt is old version?
