SYMPTOMS
When you use an Active Server Pages (.asp) page and ActiveX Data Objects (ADO) to open a recordset from a query in a Microsoft Access database, which contains any intrinsic functions (for example, Month, Left, etc.), the following error may occur:

Microsoft OLE DB Provider for ODBC Drivers error '80040e14'

[Microsoft][ODBC Microsoft Access 97 Driver] Undefined function 'xxxxx' in expression.



CAUSE
This behavior occurs when the following conditions are true:
 * The Vbajet32.dll file is version 5.0.0.7122 (ships with Visual C++ 5.0, Visual Studio Service Pack 2 and Service Pack 3) or later (MDAC 2.0 currently ships with version 6.1.8167).
 * The Visual Basic 5.0 run-time library is version 05.00.4319 (Service Pack 2 or Service Pack 3)
 * The Visual Basic 5.0 run-time library is loaded into memory. In essence, a Visual Basic component (compiled after Service Pack 2 or Service Pack 3) has been loaded into memory.

The behavior occurs because of a bug in the Visual Basic 5.0 run-time library, the Msvbvm50.dll file, version 5.1.43.19 (Service Pack 2 or Service Pack 3). The bug does not show up unless Vbajet32.dll is version 5.0.0.7122 or later.



RESOLUTION
This bug has been fixed in the Visual Basic 6.0 run-time library. If you have Visual Basic 6.0 installed, recompile your Visual Basic 5.0 components in Visual Basic 6.0. If you do not have Visual Basic 6.0 installed, you can replace the Vbajet32.dll file version 5.0.0.7122 with file version 3.0.0.6098 that ships with Microsoft Data Access Components (MDAC) version 1.5. The file can be downloaded as a part of the MDAC 1.5 install from the following Web site:

http://msdn.microsoft.com/downloads/default.asp

NOTE: After you replace the Vbajet32.dll file with the 3.0.0.6098 version, you need to reboot the Web server.



STATUS
This has been fixed in Visual Basic version 6.0.



Steps to reproduce the behavior
 Stop the Web service, and then restart it. Create a Visual Basic 5.0 Service Pack 2 or later project. Create an ActiveX .dll with one class module and name it Csimple and name the project Test. Save the project and compile it into the .dll file. Create two .asp pages. Name one test1.asp and name the second one Test2.asp. On the first page, create a connection to a Microsoft Access 97 database by means of ADO and create a recordset that prints back to the page with the following SQL statement:

SELECT Left([fieldname],1) FROM [table]

NOTE: [table] is a table in the database ane [fieldname] is a field in that table. On the second page, create an object reference to the .dll file that you created in step 2. The syntax would be something like the following line:

Set obj = Server.CreateObject("Test.CSimple")

</li> Browse the first page, Test1.asp, everything works fine.</li> Browse the second page, Test2.asp, everything works fine.</li> Return to the first page, Test1.asp, and the error occurs.</li></ol>
