Problem changing password using ADOX.Catalog.Users(User).ChangePassword

Hi Neil,

I have check your code and database file. I found that the code is correct,
however, there might be something wrong with the .mdw file, because if I
use another pair of .mdb and .mdw file with the same code, it works fine.
With further research, I found this might be a known issue. You might have
to recreate the .mdw file and users with exact same account names and
personal identification numbers (PIDs) with current version of Access.
Please check the following KB article for reference:

If anything is unclear, please feel free to reply to the post.

Hi Kevin,

I'm back again with this one. I've tried what you suggested and followed the
suggestions in the KB article. I've also tried recreating the database and
security file from scratch in both Access 2000 and 2002. No joy at all -
still getting the same errors.

What I have done though is to write a separate application to edit passwords
&, with the correct privileges, to add/edit/delete users. For this I used
the same change password code that I have posted and sent to you. This works
fine with the exact same Access DB files that refuse to work with the
solution that I sent you. I'd be happy to send you a cut down demo copy of
this if you felt it might be useful.

This experience doesn't seem to fit the mould of the problem and solution
described in the kb article and seems to suggest to me, for what that's
worth, that there is something else going on - probably in the .net side of
this.

Thanks again for all your efforts & help,

Neil R.
 
Hi Neil,

Thank you for your update and Kevin's onging efforts on this issue!

As the project can work fine on Kevin's machine with the code from your repro package, but it failed on
yours even with a New .mdb and .mdw file, I suspect the problem could be a machine specific one. To
further isolate the problem, I suggest you taking the following actoins to see if the problem can be
addressed and suppressed:

1) Copy the Database (.mdb) and the Workgroup File (.mdw) to another machine. See if the project works
fine.

2) If the problem persists, we should also create a new database and new workgroup file to see if the
problem doesn't happen in the new pair of files on the new machine. If this fails to suppress the problem, it is
really a weird one as it didn't happen on Kevin's machine.

If the problem disappears on another machine, the problelm can be narrowed to a machine specific one. If
that, I recommend you apply the latest Jet 4.0 SP8 on the problematic machine to upgrade the Jet engine
version to suppress most of the Jet engine issue:

3) If all of these cannot isolate/resolve the problem, we may establish the same environment to test this
issue fully and completely. This may take some time and we appreciate your patience and cooperation.

If there is any update Neil, please feel free to let Kevin and me know. We are here happy to be of
assistance!

I have Jet 4.0 SP8 installed on both machines & MDAC 2.8 (from the April

available updates installed & still no joy.

You have my cooperation if you wish to embark on this. I am very busy with
work at the moment though so it may be that you too have to be a little
patient with me too, but I'll always try and get back to you as quickly as
practicably possible.

Hi Neil,

I have reviewed the whole issue thread. It seems that the error doesn't
exist in the code, since:
1) The code works fine on our side
2) The code works fine if you are using it in another application to open
another MDB file.

To further confirm it, I think you can try the following step:
In the erroneous project, try using the sample code to open another MDB
file to see if it has error. Just change the MDB file name in the
connection string.

If it has no error, then apparently the root cause is in the MDB file. It
is better for us to recreate the MDB file step by step to isolate the
problem.

If it still has error, then it is really strange. I may need to suggest you
ask for help from PSS. We may need to analyze memory dump, detailed repro
sample, and etc to look into it.

Thanks very much for your patience.
