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

 - Microsoft Visual Basic Enterprise Edition for Windows, versions 6.0, 6.0 SP3, 6.0 SP4 
 - Microsoft Visual Basic Professional Edition for Windows, version 6.0 
 - ActiveX Data Objects (ADO), version 2.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

If you use a DataGrid to add a record to a server-side ActiveX Data Objects
(ADO) recordset, you receive one of the following error messages when there are
more records than the DataGrid can display:

   Invalid Bookmark

   -or-

   c0000005 (access violation)

CAUSE
=====

The Invalid Bookmark error message appears if Visual Studio Service Pack 5 (SP5)
has not been applied. The Access Violation error message appears if you apply
SP5 in addition to making an upgrade to MDAC 2.6 on the system.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Microsoft Data
Access Components 2.6. For additional information, please see the following
article in the Microsoft Knowledge Base:

   Q300635 INFO: How to Obtain the Latest MDAC 2.6 Service Pack

The easiest resolution is to switch to client-side cursors for instances where
DataGrids are used to add records to ADO recordsets. If MDAC 2.5 is installed on
the system, then an upgrade to SP5 resolves the Invalid Bookmark error. If you
apply MDAC 2.6 as well as SP5 for Visual Studio, you can use the following link
to the Component Checker tool to return to a earlier MDAC version, such as 2.5:

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

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

2. On the Project menu, choose Components, choose Microsoft ADO Data Control 6.0
   and Microsoft DataGrid Control 6.0, and then place an instance of each on the
   form.

3. Right-click the ADO Data Control and, on General tab, set up a connection
   string to a SQL Server database.

4. Select the Recordsource tab, select 2-adCmdTable, and then select a table in
   the database from the drop-down list.

5. On the ADODC1 property sheet, set the CursorLocation property to
   2-adUseServer.

6. On the property sheet, select the DataGrid, and then set AllowAddNew to True
   and DataSource to ADODC1.

7. Run the project and press the PAGE DOWN key until you get to the bottom of
   the DataGrid.

8. When you get to the last row, click in a field and begin to add a record.

When you move off of the newly added field in the new record, you receive one of
the two error messages listed in the "Symptoms" section unless Visual Studio SP5
has been applied on a computer that is running MDAC 2.5.
