// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Dim sftp As New Chilkat.SFtp

// Connect to the SSH server.  
Dim hostname As String
hostname = "sftp.example.com"
Dim port As Int32
port = 22
Dim success As Boolean
success = sftp.Connect(hostname,port)
If (success <> True) Then
    System.DebugLog(sftp.LastErrorText)
    Return
End If

// Authenticate with the SSH server.  Chilkat SFTP supports
// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.
success = sftp.AuthenticatePw("myLogin","myPassword")
If (success <> True) Then
    System.DebugLog(sftp.LastErrorText)
    Return
End If

// After authenticating, the SFTP subsystem must be initialized:
success = sftp.InitializeSftp()
If (success <> True) Then
    System.DebugLog(sftp.LastErrorText)
    Return
End If

// Check to see if a file exists

// The return value is one of the following values:
// -1: Unable to check. Examine the LastErrorText to determine the reason for failure.
// 0: File does not exist.
// 1: The regular file exists.
// 2: It exists, but it is a directory.
// 3: It exists, but it is a symlink (only possible if followLinks is false)
// 4: It exists, but it is a special filesystem entry type.
// 5: It exists, but it is an unkown filesystem entry type.
// 6: It exists, but it is an socket filesystem entry type.
// 7: It exists, but it is an char device entry type.
// 8: It exists, but it is an block device entry type.
// 9: It exists, but it is an FIFO entry type.
