(MFC) OneDrive -- Streaming File Upload

See more OneDrive Examples

Uploads a local file by path to the signed-in user's OneDrive. This uses OneDrive's simple upload API to upload in a single API call. Uploading in this way only supports files up to 4MB in size. The 4MB limitation is a OneDrive limitation, not a Chilkat limitation. (See the other example(s) for uploading larger files.)

Note: This example requires Chilkat v9.5.0.68 or greater.

For more information, see https://docs.microsoft.com/en-us/onedrive/developer/rest-api/api/driveitem_put_content?view=odsp-graph-online
