posted May 23, 2005 11:19 AM I created a class with an object within i.e. Private WithEvents Ftp1 As New Dart.PowerTCP.SecureFtp.Ftp When needed I retrieve information from various folders (one at a time) and programmically download files using the form from the demo Dart project called "FtpListView" named "Transfer". The downloading works fine but can not get the progress bar to update. In debugging I see the check below (removed argument list for inserting into this message) Private Sub Ftp1_Progress() Handles Ftp1.Progress If Not frmProg Is Nothing Then ... always is nothing. The code below is triggered each time a file needs to be downloaded and is called from reading a remote folder listing: Private Sub DoRetrieve(ByVal strCountyName As String) Ftp1.FileType = FileType.Image Try Dim frmProg As New frmTransfer(Ftp1, FileName.Name, LocalFilePath() & "\" & FileName.Name, frmTransfer.TransferType.Retrieve) frmProg.ShowDialog() frmProg = Nothing Catch ex As Exception Errors.Add("County: " & strCountyName & " Operation:DoRetrieve() Error Message:" & ex.Message) End Try End Sub NOTE: I declared Transfer form as shown below: Private frmProg As frmTransfer Any thoughts why the transfer form is coming up as nothing? Is there something I am not doing right? Thanks for your time in reviewing this question, Kevin |

posted May 23, 2005 11:31 AM In this case frmProg is a local variable and has no meaning in the Progress event. Instead of dimming a new local one you should be using the form level one (like we do in the sample) |
