(PowerBuilder) Upload using Azure Storage Account Shared Access Signature (SAS) AuthorizationSample code to upload binary bytes to a block blob in Azure Cloud Storage using an Azure Storage Account Shared Access Signature (SAS) Authorization. This creates a block blob, or replaces an existing block blob. Note: The maximum size of a block blob created by uploading in a single step is 64MB. For larger files, the upload must be broken up into blocks. There is another Chilkat example for that.. Note: This example requires Chilkat v9.5.0.65 or later.
