I am trying to read the corrupt image xls document using poi library.But
problem is I am retrieving the bytesRemaining value wrongly
Actual value I am getting:
55028
Expected value:
120564
as bytes read is also 120564 which causes negative array index exception
in the line _remainingData = new byte[bytesRemaining].how can be it fixed?
Looks like your file has less data in it than it ought to for a given
record, and we're reading off the end of it
please provide any suggestions
First, we need to know if it's a corrupted file, or if it's something we
can work around. Does the Binary File Format Validator pass it? Can Excel
read it? Where did it come from?
Then, you'll likely need to read the [MS-XLS] file format spec, and
compare the values in your file to that. Are there optional bits that POI
is always reading for example?
