ACC97: "About MDE Files" Help Topic Incorrect in Microsoft Access 97 (162451)
The information in this article applies to:
This article was previously published under Q162451 Moderate: Requires basic macro, coding, and interoperability skills.
SYMPTOMS
The "About MDE files" Help Topic contains the following paragraph:
If your database contains Visual Basic code, saving your database as
an MDE file compiles all modules, removes all editable source code,
and compacts the destination database. Your Visual Basic code will
continue to run, but it cannot be viewed or edited, and the size of
your database will be reduced due to the removal of the code.
Additionally, memory usage is optimized, which will improve
performance.
The last sentence in this paragraph is incorrect. MDEs are no faster than
the equivalent, fully compiled and compacted, MDBs. Visual Basic for
Applications uses the same memory optimizations for both; that is, source
code is not loaded if the project is compiled. MDEs can never decompile
like MDBs, which makes them run consistently at the same speed. MDBs
can decompile when changes are made to the underlying Visual Basic code,
which make them appear to run more slowly.
