Digital Certificate question - Microsoft Access / VBA

troy_lee

We have an application developed by one developer. He compiled the
database into an application and digitally signed the application. He
doesn't know if he used selfcert of makecert to make the key.

The problem is I am creating additional forms now for the database on
a different machine. Whenever we try and incorporate the forms I
develop into the application, the application fails on some users'
machines. We suspect it is because I am not developing with the same
digital certificate the application was originally signed with.

Do I need to import the the original digital certificate for my
development efforts?
If so, how do I do that?

Thanks.

What do you mean by "applicatio n fails"? Do the changes not save or does the
db not open afterwards? What's the error message?

If he used self sert the app will only open on his pc without the security
messages if he has macro security set to medium, the other pcs will show the
security messages if they don't have macro security set to low.

If you modify the design, you invalidate that certificate. You need to
purchase your own digital certificate if you're developing databases for an
audience that requires digital signatures. OTH if this other developer is in
your organization, after your changes he can sign the db with the digital
certificate he has set up on his pc. Or work with your network admins to set
up the organizational digital certificate on your pc too.

Thanks for the response.

The failure we get is that the application won't execute after
install. Access indicates some type of fatal error and closes. This
only happens on some machines, of which some only have runtime. This
is a real pain and no one seems to know why this is happening? Your
thoughts please.

The most common reason for a db app to close with a fatal error and no error
message with the Access runtime is from poor vba coding and inadequate
testing and error handling. The runtime requires a robust design and coding.

Look at the new forms you added. How many procedures don't have any error
handling or rely on "On error resume next"? If it's more than zero, start
adding error handling.

Thanks a lot. I will look at this a little closer. I was not aware of
the stringency of runtime.

Make sure it compiles, too. It's easy to forget that step after importing a
bunch of new forms.
