(MFC) Backblaze S3 Upload String

See more Backblaze S3 Examples

Demonstrates how to upload the contents of a string to an Backblaze bucket.

The Chilkat S3 functions in the HTTP class are compatible with the Backblaze service. However, because of some specific issues, Chilkat v9.5.0.89 or later is needed.
