Clever Internet Suite - Uploader Description

	Uploader Description

Features | Detailed Description

Available in VCL and ActiveX editions.

The Uploader component allows you to upload the Internet-resources asynchronously and obtain all necessary information related to those resources without interfering into the main application processes.

This component supports uploading data via HTTP, HTTPS and FTP protocols. To upload data through HTTP protocol, the Uploader may perform single POST request or multiple separated requests with pre-defined portions of data. Uploading process can be visually represented with a progress bar, stop/resume and many other useful features.

Please see the Demos code (Uploader, SubmitFile) and also the indexed Help documentation provided with the Clever Internet Suite installation for more details about using this component.

The most common members of the Uploader component can be seen below:
