FTP Download with Progress Monitoring

Download: Chilkat .NET Assemblies

Demonstrates how to download a file from an FTP server with progress monitoring event callbacks. Also demonstrates how to abort an FTP download while in progress.

	    // Progress monitor callback -- called each time the percentage completion
	    // updates to a larger value.
	    public void OnFtpPercentDone(object source, Chilkat.FtpPercentDoneEventArgs args)

		// args.PercentDone is an integer value between 1 and 100.
		progressBar1.Value = args.PercentDone;
		
		// args.Abort can be set to True to abort the FTP trabsfer while in progress.
		// This example aborts the FTP transfer after it is 60% complete.
		if (args.PercentDone >= 60)
		{
		    args.Abort = true;
		}
	    }
