SQL Server Requires Chilkat v11.7.0+

Box: Download Binary Content into BinData

See more Box Examples

Run the reusable setup once per HttpCurl object, then select names and execute the operation. The setup is repeated here only to make this published example independently runnable. Download a small file into memory. For large files use the direct-to-disk example.

See the Box API guide for setup and the complete workflow.
