Access Run Time in the MAC environment Err: object not set

[WindAndWaves]

Hi Everyone,

Here is another question:

I run a database in Access RT in a Virtual PC environment.

Every now and then I get an error: "Object Not set", which then freezes
everything. Not even CTRL + ALT + DELETE can really help.

Any idea what I can do to solve this problem???

No really, you just expect too much from an emulator. They work until
they don't. I'm assuming this is not a case where the error is
reproducible on a PC.

Yes, I agree with all that (virtual PC may not do everything), but I do
find that everything else works, so i probably just need to change one line
in a procedure or so.

The thing is, it comes up completely randomly, almost like a timer, but i do
not use any events like that, as far as I know.

How could I analyse the bug??? or cath it somewhere???

You could try the standard "on error goto" error handler in every
procedure. If it truly is an imperfection in the emulator, that may
not help though.

as far as I know i have in each procedure (although i sometimes use on error
resume next). Is there no way to find out where it happens in another
way???

Thank you for your help.

No idea as to why it freezes. I was getting this message when I had declared a
global database variable but for some reason somewhere it was getting lost. So I
ended up resetting that variable every time the user hit the main menu.

When I'm programming this would get lost when I was debugging code and hitting the
End code button. However if you're running on a runtime then this isn't the case.

Don't use a global database variable. Instead, use a global function
that returns an object of type DAO.Database, since you can make that
function internally self-healing by re-initializing your actual
global variable, if necessary. My code for this follows my sig.
