Mastering TS Net

[Charles Warwick]

Hi BR,

There are a series of lessons on tsNet on the LiveCode website:

http://lessons.livecode.com/m/4071/c/235433

If you are looking for an example of how to download something direct to a file, the lesson called “How to asynchronously download via SFTP directly a file” should help.

The same concepts apply for downloading to a file regardless of the protocol being used.

If you can’t quite find an example lesson that answers what you need, let me know and I will get one organised.

Regards,

Charles
