(Visual FoxPro) Directory Existence Check

How to test if a directory exists on an FTP server.

A good way to check to see if a directory already exists is to try to "cd" to that remote directory by calling ChangeRemoteDir. If it succeeds, then the directory exists. If not, then it does not exist. An alternative method is to set the ListPattern = "*" and then iterate over the files/directories, looking for the directory.

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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Ftp2')
loFtp = CreateObject('Chilkat.Ftp2')

loFtp.Hostname = "ftp.example.com"
loFtp.Username = "login"
loFtp.Password = "password"

* Connect and login to the FTP server.
lnSuccess = loFtp.Connect()
IF (lnSuccess <> 1) THEN
    ? loFtp.LastErrorText
    RELEASE loFtp
    CANCEL
ENDIF

* Does the "temp" directory exist?

lnDirExists = loFtp.ChangeRemoteDir("/temp")
IF (lnDirExists = 1) THEN
    ? "Yes, the temp directory exists."
    *  Yes, it exists. Restore the current remote dir:
    lnSuccess = loFtp.ChangeRemoteDir("..")
    IF (lnSuccess <> 1) THEN
        ? loFtp.LastErrorText
        RELEASE loFtp
        CANCEL
    ENDIF

ENDIF

* Alternatively, you may set the ListPattern = "*" and 
*  look for the directory:
loFtp.ListPattern = "*"

n = loFtp.GetDirCount()
IF (n < 0) THEN
    * Failed to get directory listing based on ListPattern
    ? loFtp.LastErrorText
    RELEASE loFtp
    CANCEL
ENDIF

IF (n > 0) THEN
    FOR i = 0 TO n - 1

        lnIsDir = loFtp.GetIsDirectory(i)
        IF (lnIsDir = 1) THEN

            lcFname = loFtp.GetFilename(i)
            IF (lcFname = "temp") THEN
                ? "Found temp directory!"
                lnSuccess = loFtp.Disconnect()
                RELEASE loFtp
                CANCEL
            ENDIF

        ENDIF

    NEXT
ENDIF

lnSuccess = loFtp.Disconnect()

RELEASE loFtp
