disappearing value (1 Viewer)

[bauer]

I tried making my own security for a databse of mine, and I have a recurring problem.
In order to keep the state of security, I use a variable to hold what security level this user has. For some odd reason every so often the variable will sort of lose this value, and in essence log a person out (I have as a default no permissions if there is no value in this variable).

If anyone can please explain to me why this might be happening, or maybe even a fix, I would greatly appreciate it.

In case you were wondering why I made my own, I did this b/c I didn't want all access databases under this security.

Are you keeping the value in a Public module? If the user moves from form to form, that "username" will need to be checked during each move the way I understand. Just a thought.

I have it as such:
Public UserID As Long
in a module

 

[jwindon]

So on the onload event of your forms and things you are calling the module and checking the value against some kind of "permissions" list?

I have found when using this method that you need to set the variable several times if you are referencing it regularly. I usually use a few crucial forms that I know have to be opened.

jwindon: yes

Rich: I'm sorry, but I didn't understand. How and when do you set the variable several times?
I have a log in form where they log in, and there I set the variable. When else should I do it?

Thanks

Try first throwing a few message boxes on your form events to narrow down which forms, etc are not keeping the user name. Maybe there is a logic error going on somewhere.

I've experienced a similar problem but only when the database was still under development. Untrapped errors seemed to cause the problem. So, I started using a hidden form to hold the values I needed throughout a session. This seems to be more stable.

to Jwin: I have made a form that I use to constantly check who is logged on, and I think it is like Pat was saying that when an error happens.
I think I'll try putting it on a form. Thank you!
