TITLE   :BUG: Internet Transfer Control (SP2) Username and Password Fails
PRODUCT :Microsoft Visual Basic for Windows
PROD/VER:WINDOWS:5.0,97sp2
OPER/SYS:
KEYWORDS:kbVBp500

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Visual Basic Professional Edition for Windows, version 5.0 
 - Microsoft Visual Basic Enterprise Edition for Windows, version 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

The Internet Transfer Control included in Service Pack 2 for Visual Studio 97 is
unable to make authenticated connections for either the HTTP or FTP protocols.
Anonymous connections still work. If you try to specify the Username and
Password, you will get the following error:

   Run-time error '35754'
   Unable to connect to remote host

CAUSE
=====

This version of the control does not properly handle the Username and Password
properties.


RESOLUTION
==========

To restore this functionality temporarily, replace the Msinet.ocx included with
SP2 with the Msinet.ocx on the Visual Basic 5.0 CD.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

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

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

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

3. Place an Internet Transfer Control 5.0 (Inet1) on Form1 and add the following
   code:

         Private Sub Inet1_StateChanged(ByVal State As Integer)
          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(1024, icString)
              DoEvents

              Do While Not bDone

                  strData = strData & vtData
                  ' Get next chunk.
                  vtData = Inet1.GetChunk(1024, 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, click Start (ALT, R, S) or press the F5 key to run the
   program. Click the Command1 button, and you will see error described above.

NOTE: The above sample demonstrates the problem with FTP, but it also occurs for
the HTTP protocol
