TITLE   :BUG: ADO 2.0 Reference Cannot Be Saved in VB 6.0 With VS SP4
PRODUCT :Microsoft Visual Basic for Windows
PROD/VER::6.0,6.0 SP4
OPER/SYS:
KEYWORDS:kbADO200 kbVBp600 kbVS600sp4bug

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

 - Microsoft Visual Studio 6.0 SP4, used with:
    - Microsoft Visual Basic Professional Edition for Windows, version 6.0 
    - Microsoft Visual Basic Enterprise Edition for Windows, version 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

In Visual Basic 6.0, with the Visual Studio 6.0 Service Pack 4 installed, a
reference to the Microsoft ActiveX Data Objects (ADO) 2.0 Library (msado20.tlb)
cannot be saved. Instead, the reference is automatically upgraded to Microsoft
ActiveX Data Objects (ADO) 2.5 Library (msado15.dll) when the project is
re-opened.

STATUS
======

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

This bug was corrected in Visual Studio 6.0 Service Pack 5. For additional

MORE INFORMATION
================

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

1. Create a new Standard EXE project in Visual Basic. Form1 is created by
   default.

2. On the Project menu, click References, and then select Microsoft ActiveX Data
   Objects 2.0 Library. This associates msado20.tlb with the project.

3. Save and close the project.

4. Re-open the project.

5. On the Project menu, click References, and note that Microsoft ActiveX Data
   Objects 2.5 Library (msado15.dll) is now selected.

NOTE: If a project uses or references the adodc control (msadodc.ocx) or the data
environment designer (msderun.dll), then the upgrade from ADO 2.0 to ADO 2.5 is
done automatically because both of these components require ADO 2.5.
