Hello.

It seems that there is an access error. Do you have access to the file where you tries to export report?

Thank you.

hello,

i think, it's not a problem with access right to read/write file.

i find that this exception is thrown always when:
1. turn on computer
2. start my app to generate PDF documents in parallel (when documents are generated "one after another", no error is occured)

later - when app is started again with same data, all is ok.

do you have any idea, what's wrong?

thanks

we did (probably) find problem:
memcpy

in StiPdfExportService.CreateSignature

On input, buffer sizes are usually specified large enough to ensure that the largest possible output data will fit in the buffer.
