Upload a file using powershell and the WinSCP .NET library with upload progress feedback

fileupload.ps1

# Using the beta version of WinSCP http://winscp.net/eng/download.php
# Call this script to upload a file via FTP with progress feedback
# e.g. 
# .\fileupload.ps1 -username "myusername" -password "mypassword" -localfile "C:\files\MyFile.exe" -remotefile "/public_html/files/MyFile.exe"
# NOTE: This script assumes the WinSCP binaries are in a sub directory to the script. You can probably pass that as a parameter to be more flexible.

Hey @fushnidsoft, nice program. Can you please tell me what 'CPS' is in your FileProgess function? ($e.CPS)

@OoMaH This might be 6 years too late but I was wondering the same thing and found this in the documentation

int CPS | Transfer speed (bytes per second). Read-only.

Thanks, very helpful. What is the correct way to print the success status at the end of the transfer?
