Steps to Reproduce Behavior

Run Visual Basic or, if Visual Basic is already running, choose New Project from the File menu (ALT, F, N). Form1 is created by default.

Place an Internet Transfer Control (Inet1) on Form1 and add the following code:

      Private Sub Inet1_StateChanged(ByVal State As Integer)
         Dim strMess As String ' Message variable.
         Select Case State
         ' ... Other cases not shown.
         Case icError  ' 11
           ' Get the Text of the error.
         strMess = "ErrorCode: " & Inet1.ResponseCode & " : " &
                                             Inet1.ResponseInfo
         End Select
      End Sub

Place a CommandButton (Command1) on Form1 and add the following code:

      Private Sub Command1_Click()
           ' download FTP files
           Dim b() As Byte
           Dim strURL As String

           ' Set the strURL to a valid address.
           strURL = "FTP://GenericServer/FileToDownload.bin"

           ' Retrieve the file as a byte array.
           b() = Inet1.OpenURL(strURL, icByteArray)

           ' ** create directory on your machine with directory target
           Open "C:\Target\FileToDownload.bin" For Binary Access _
           Write As #1
           Put #1, , b()
           Close #1
       End Sub
