Steps to Reproduce Behavior
---------------------------

1. Start a new Standard EXE project. Form1 is added by default.

2. From the Project menu, choose Components, and select the Internet
   Transfer Control 5.0(SP2) into the project if it is not already loaded.

3. Place an Internet Transfer Control 5.0(SP2) on Form1 and add the
   following code:

      Private Sub Inet1_StateChanged(ByVal State As Integer)
       Const lCHUNKSIZE As Long = 1024
       Dim vtData As Variant ' Data variable.

       Select Case State
       ' ... Other cases not shown.
       Case icError ' 11
           ' In case of error, return ResponseCode and

      ' ResponseInfo.
           vtData = Inet1.ResponseCode & ":" & _
           Inet1.ResponseInfo

       Case icResponseCompleted  ' 12
           Dim strData As String: strData = ""
           Dim bDone As Boolean: bDone = False

           ' Get first chunk.
           vtData = Inet1.GetChunk(lCHUNKSIZE, icString)
           DoEvents

           Do While Not bDone

               strData = strData & vtData
               ' Get next chunk.
               vtData = Inet1.GetChunk(lCHUNKSIZE, icString)
               DoEvents

               If Len(vtData) = 0 Then
                   bDone = True
               End If
           Loop

          MsgBox strData
       End Select
      End Sub

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

      Private Sub Command1_Click()
          Inet1.UserName = "Username"
          Inet1.Password = "Password"
          Inet1.URL = "ftp://YourFTPServer"

          Inet1.Execute , "DIR"
     End Sub

5. From the Run menu, choose Start (ALT, R, S), or press the F5 key to run
   the program. Press the Command1 button and you will see error described
   above.
