The information in this article applies to:
After installing Internet Explorer 4.0 (beta 2), ADODB code using a recordset may raise an error condition with an error code of 0x800A0BB9 or -2147439686. This error code may occur when performing operations that use ADODB.Recordset objects in conjunction with other ADODB objects as shown in the example below:
dim cnnObj as new ADODB.Connection dim rstObj as new ADODB.Recordset dim strSource as string ... rstObj.Open strSource, cnnObj
This only occurs if the user has not already installed ADO 1.5.
Internet Explorer 4.0 beta installs Msador15.dll, which when registered puts two sets of PROGIDs in the registry, both of which point to the newer Recordset CLSID (the one for ADOR 1.0 Recordset and ADODB/ADOR 1.5 Recordset). Only the "ADOR.Recordset" PROGID should be entered in the registry.
After installing Internet Explorer 4.0, the user can go to the following folder:
\program files\common files\system\ado
Then you can re-register ADO's Recordset object correctly with the following command:
However, if the user already has Msado15.dll installed on their system, then there will not be any conflict as a result of the ADOR registration bug. You should not re-register Msado10.dll after ADO 1.5 has been installed on the machine.
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.
This bug only affects users of Active Server Pages 1.0 who install Internet Explorer (4.0 Beta 2).
