(Classic ASP) Google Drive - Upload File

See more Google Drive Examples

This example demonstrates how to upload a file to Google Drive. The assumption is that the file can be loaded into memory and uploaded. It is also possible to stream large files to Google Drive, but the code required is a little more complex.

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' This example uses a previously obtained access token having permission for the 
' Google Drive scope. 
' See Get Google Drive OAuth2 Access Token

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.AuthGoogle")
