ActiveX for 32-bit and 64-bit Windows

Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// See Global Unlock Sample for sample code.

// This example uses a previously obtained access token having permission for the 
// Google Drive scope.

// -------------------------------------------------------------------------
// A multipart upload to Google Drive needs a multipart/related Content-Type

// Specify each part of the request.

// The 1st part is JSON with information about the file.

// To place the file in a folder, we must add a parents[] array to the JSON
// and add the folder ID.  
// In a previous example (see Build Local Metadata Cache
// we built a local cache to make it easy to lookup file IDs given a file path.
// Let's find the file ID for the folder "testFolder/abc/123"
