FIX: An ADO application crashes after you install Windows Server 2003 SP1 or Windows XP SP2 (911570)


The information in this article applies to:

  • Microsoft Data Access Components 2.8 Service Pack 1 (SP1)
  • Microsoft Data Access Components 2.8

SYMPTOMS

After you install Microsoft Windows Server 2003 Service Pack 1 (SP1) or Microsoft Windows XP Professional Service Pack 2 (SP2), a Microsoft ActiveX Data Objects (ADO) application crashes. This problem occurs when the ADO application uses a pointer to a wide character string.

Note A pointer to a wide character string that is used by an Automation data-manipulation function is called a binary string or a BSTR.

For example, you may experience this problem when you use the following ADO CRecordset::Update code example to update a BSTR field with the value of a BSTR field from another record set.
Dim rstComponenti as New ADODB.Recordset
....
rstComponenti.Update "description",rstComponentiApp.Fields("description")

CAUSE

This problem occurs because of a regression that was introduced in a post Microsoft Data Access Components (MDAC) 2.8 RTM version of the Msado15.dll file.
