(VB.NET) SFTP Debug Log File Path

Demonstrates how to use the DebugLogFilePath property to get information if a Chilkat method crashes or hangs.

Chilkat .NET Downloads Chilkat .NET Framework Chilkat for .NET Core

Dim sftp As New Chilkat.SFtp

' Insert this code just before the method call that crashes or hangs.
sftp.VerboseLogging = True
sftp.DebugLogFilePath = "/some/file/path/sftp_debug_log.txt"

' Make the call that crashes or hangs,
' for example, if the method is DownloadFileByName:

Dim remoteFilePath As String = "..."
Dim localFilePath As String = "..."
Dim success As Boolean = sftp.DownloadFileByName(remoteFilePath,localFilePath)

' Note: If the method returns control to your application code, then it did not crash within Chilkat.
' The DebugLogFilePath property causes all information that would be recorded in the LastErrorText to be emitted to the
' log file (with immediate file write flushing, i.e. no buffering).  Thus, in a crash situation,
' the log file will contain information up to the point of the crash.

If (success = False) Then
    Debug.WriteLine(sftp.LastErrorText)
    Exit Sub
End If
