This issue shows how to use the Microsoft WININET.DLL to retrieve a file from an FTP server. It does not use the Microsoft Internet Controls, so there is one less file you have to worry about including with your application.
This class allows you to download a file from an FTP server very easily. We will be enhancing this class in the next issue or two. If you have specific requests, please get them to us as soon as possible at email@example.com
Basically to use this class you need to set four properties and call one method. The additional properties of this class will be discussed in the next issue. We've included the basics to get you started.
Public ServerName As String Public SourceFilename As String Public DestinationFilename As String Public BinaryMode As Boolean
Public Sub OneStepDownload()
This is the method that actually connects to the server, changes to the appropriate directory and downloads a file. It will raise some errors if necessary, such as if the server can not be connected to or the file can not be found.
Private Sub cmdDownload_Click() Dim ftp As New cFTP On Error GoTo Handler ftp.ServerName = "www.microsoft.com" ftp.SourceFilename = "/pub/testfile.exe" ftp.DestinationFilename = "c:\test.exe" ftp.BinaryMode = True ftp.OneStepDownload Exit Sub Handler: MsgBox Err.Description End Sub
