Cannot create MDE error message...

[Guest]

I have Office XP. opsys WinXP Pro.

Front end db is Access 2002 fmt. Trying to MDE it. Starts... then error
Cannot create MDE... OK button only .. no help/explaination. ??? any
Ideas. This is a pretty big front end... 150MB. I think anyway... is
150MB large for a front end db?... but the real question is why does it
keep bombing when I try to MDE it?

Four possibilities come to mind:

1. There may be coding errors in your database. The database cannot be converted to an MDE file if
there are any coding errors. Open any code module and, from the VBA menu, select Debug, then
Compile. If there are any errors, you will see an error message and the problem line of code will be
highlighted. You will need to correct any problems the compiler finds. Continue compiling until the
compile process completes with no error messages at all. Then try making an MDE file from the
database. Always keep lots of backup copies of the original MDB file.

2. If you are using Access 2002 or 2003, the default database format is Access 2000 unless you have
changed this. Unfortunately, if you use the Access 2000 database format in Access 2002 or 2003, you
cannot create an MDE. You may only create an MDE of an Access 2000-format database using Access
2000. So to make a 2002 MDE file, you must convert it to 2002 format and use 2002 to make the MDE
file. The same is true for 2003: you need to convert the file to 2003 format and use 2003 to make an
MDE in 2003 format.

3. See this link for another possibility:
ACC2002: Error Message: "Microsoft Access Was Unable to Create an MDE Database"
http://support.microsoft.com/?id=289686

4. Using methods of the DbEngine object without explicitly providing the DbEngine qualifier. For
example: OpenDatabase(...) instead of DbEngine.OpenDatabase(...). This can lead to strange DAO
licensing & other errors, including the inability to create an MDE.

150MB large for a front end db?

Yup. One should have the queries, forms, reports, modules, macros, and
DAP's in the front end. Tables and relationships should be in the back end.
Occasionally, small static tables are placed in the front end, but this
shouldn't be pushing the database file size to 150 MB. Your front end likely
has much data that should be stored in the back end.

but the real question is why does it
keep bombing when I try to MDE it?

Actually front end has very little data. A couple of small static tables.
One has 8 .5mb .jpgs, but the rest is forms..etc. I will check to
clean up some unused items. Should have done already, but got sloppy. I
cleared out one ad line in debugger... got the MDE to complete. thank you!
