I am getting an exception that appears to be coming from PGPReaderX::DecryptAndVerify.
Cannot create file C:\DOCUME~1\wilson\LOCALS~1\Temp\NULL-2081000.dat -- file may be in use or read-only.
That is not the filename I specified so I suspect it to be some internal temp filename. Any ideas?

I am looking at my code and I just discovered I am doctoring the Exception text. The original exception text is
"Cannot create file C:\DOCUME~1\wilson\LOCALS~1\Temp\NULL-2081000.dat"

The temporary file must be created for some purpose. In VCL and .NET editions there's OnTemporaryStream event avaialble that lets you create a temporary stream. But in ActiveX edition this is handled automatically. The problem should not happen as the temporary file is created in the temporary folder. If the problem re-appears, check whether the path exists and whether the file can be created in the specified folder (or the file already exists and is opened or read-only).

Also please specify the version of SecureBlackbox that you are using and any other details about your use of the component - maybe you are using it from the service application (if it's even possible with VB) or from constrained environment such as the web server.

Sincerely yours
Eugene Mayevski
