ConnectFailReason

See more FTP Examples

The ConnectFailReason property can be examined to determine the reason why the Connect method failed. The possible values are listed in the source code below: PowerBuilder

integer li_rc
integer li_Success
oleobject loo_Ftp
integer li_FailReason

li_Success = 0

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

    // 0 = success
    // 
    // Normal (non-TLS) sockets:
    // 1 = empty hostname
    // 2 = DNS lookup failed
    // 3 = DNS timeout
    // 4 = Aborted by application.
    // 5 = Internal failure.
    // 6 = Connect Timed Out
    // 7 = Connect Rejected (or failed for some other reason)
