Comment:

The simplicity and small size of this code does impress. Though there is no way - to my knowledge - to attach a progress bar to a download, since Visual FoxPro does not support callback functions.

The URLDownloadToFile sends HTTP GET and receives a response back from a server. Upon success the response contains a requested file.
