strServer = FTP Server’s address “ftp.triliumsoftware.com”
strUserName = FTP UserName “user1”
strPassword = FTP Password “password1”
bPassive = true = Passive Connection | false = Non Passive Connection
iPort = FTP Server Port 21

Uploading a file

Public Declare Function UploadFile Lib "TriliumNETFTP.dll" (ByVal strFile As String, ByVal strFile2 As String, ByVal bBinary As Boolean) As Boolean

strFile = File “/File” Server File Name
strFile2 = File “/File” Pocket PC File Name

Downloading a file
