GoogleDrive Control
Properties Methods Events Configuration Settings Errors
The GDrive component provides easy file and folder management.
Syntax
GoogleDrive
Remarks
GDrive allows quick and simple management of files and folders stored in Google Drive.
To upload a file, simply call UploadFile and specify the file you wish to upload. To list files and folders, call ListResources. Resources are described by the Resource* properties. Setting ResourceIndex selects a specific resource and allows you to inspect the related properties.
Call DownloadFile to download a file. Other file and folder management functions include CreateFolder, CopyResource, DeleteResource, MoveToTrash, RestoreFromTrash, UpdateResource, and more.
In addition you can modify permissions and child-parent relationships. Please see the Methods section of the documentation for a full list of supported methods.
This service supports authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth control or
a separate process. Once complete you should have an authorization string which looks like:
Bearer ya29.AHES6ZSZEJzATdZYjeihDn5W-VrXSsxEZu5p0pclxGdKKQAssign this value to the Authorization property before attempting any operations. Consult the Google documentation for this particular service for more information about supported scope values and more details on OAuth authentication.
