ACC2: DAO2016.DLL Not Available from External ApplicationsID: Q115899
|
Advanced: Requires expert coding, interoperability, and multiuser skills.
You cannot call the DAO2016.DLL file from an application written in C to
use DAO code to control Microsoft Access tables.
The only application that can call the DAO2016.DLL file is Microsoft Access
version 2.0. Trying to call this dynamic-link library (DLL) from any other
program will not work and is not supported by Microsoft.
DAO2016.DLL (the filename refers to Data Access Objects, version 2.0, 16
bit) is the DLL that Microsoft Access uses from Access Basic to modify
database objects in the Microsoft Jet database engine.
If you try to use OLE functions from C/C++ to use this DLL, you will
receive the error message "VBAJET.DLL not found." This is a misleading
error message in that the file VBAJET.DLL does not exist as part of the
Microsoft Access installation at all. A more appropriate error message
would be "Feature not available."
Using tools such as OLE2VIEW.EXE from Microsoft Visual C++, it is possible
to look at some of the objects and methods that are exposed in the
DAO2016.DLL file. This is analogous to looking at the entry points to a
DLL, except that the information is in a form that is more useful and
easier to decode.
While these methods are listed, there is no documented way to call them,
and they are not registered in the Microsoft Windows Registration database
as OLE Methods that are available for OLE Automation.
Neither Microsoft Access nor the Microsoft Jet database engine are OLE
Servers. They cannot be controlled using OLE Automation techniques.
