FTP Sync Upload Tree w/ Must-Match Filename Constraints

See more FTP Examples

Demonstrates how synchronize a directory tree in the upload direction, but only upload files matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

Dim success As Boolean = False

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

Dim ftp As ChilkatFtp2
ftp.Initialize("ftp")

ftp.Hostname = "ftp.something.com"
ftp.Username = "my_login"
ftp.Password = "my_password"

'  Connect and login to the FTP server.
success = ftp.Connect
If success <> True Then
    Log(ftp.LastErrorText)
    Return
End If


'  Set the current remote directory to the root of
'  the tree to receive the uploaded files.
success = ftp.ChangeRemoteDir("/subDir1")
If success <> True Then
    Log(ftp.LastErrorText)
    Return
End If


'  Possible synchronization modes are:
'  mode=0: Upload all files
'  mode=1: Upload all files that do not exist on the FTP server.
'  mode=2: Upload newer or non-existant files.
'  mode=3: Upload only newer files. If a file does not already exist on the FTP server, it is not uploaded.
'  mode=4: transfer missing files or files with size differences.
'  mode=5: same as mode 4, but also newer files. 

'  This example will upload all files, but only those files having filenames
'  that match *.gif and *.eml

'  Imagine our local directory tree has these files and directories:

'  	accentedLatin1.txt
'  	accentedUtf8.txt
'  	alice.key
'  	anter_cert.pem
'  	chiliPepper.gif
'  	helloWorld.pdf
'  	abc/chiliPepper.gif
'  	abc/ghk/
'  	data/chiliPepper.gif
'  	data/xyz/dkimHtmlBody.txt
'  	data/xyz/dkimVerifyTest.eml
'  	data/xyz/emailForCreateDsn.eml
'  	text/frenchUtf8.txt
'  	text/helloWorld.txt
'  	text/PolishEmailBody.txt
'  	text/something/

ftp.SyncMustMatch = "*.eml; *.gif"
Dim mode As Int = 0
success = ftp.SyncRemoteTree("c:/temp/subDir1", mode)
If success <> True Then
    Log(ftp.LastErrorText)
    Return
End If


success = ftp.Disconnect

'  Show the files downloaded.
Dim st As ChilkatStringTable
st.Initialize
ftp.GetSyncedFiles(st)

Dim numFiles As Int = st.Count
Dim i As Int = 0
Dim remoteFilename As String
Do While i < numFiles
    Log(st.StringAt(i))
    i = i + 1
Loop

'  Output showing the files uploaded:

'  chiliPepper.gif
'  abc/chiliPepper.gif
'  data/chiliPepper.gif
'  data/xyz/dkimVerifyTest.eml
'  data/xyz/emailForCreateDsn.eml
