RE: Disable close button on Splash screen windows v12

[truegold via 4D_Tech]

Hi Tim,

Ok, will experiment and see how ti works out.

I will then need to suppress and 4D dialog and handle it programmatically.

Thanks for the help,
John...

RE: Disable close button on Splash screen windows v12

[Timothy Penner via 4D_Tech]

Hi John,

I just ran some quick tests and I think the most likely scenario here is that 
you still need to assign a password to Designer (which is required to enable 
the 4D password system).

Enabling the 4D Password System is a requirement for many features in 4D that 
pertain to the users and groups, this includes managing plugin access, 
preventing users from cancelling the backup while it is running, and also the 
"Default User".

The "Default User" setting will be ignored if the 4D Password System is not 
enabled; meaning that anyone who opens the application will be automatically 
logged in as Designer.

Did you set a password for Designer?
^ This must be done in order to activate the 4D Password system.

Did you set a Default User in the security tab?
^ This allows the default users to bypass the login screen that would usually 
be seen after adding a password to Designer.

Why do you need to assign users to a group after the custom login?

Ok …

So I already have a group created “Admin" that is set to “Design Access” in 
Database Settings->Security. It looks like it includes Designer and 
Administrator.

I have group named “Default Group”.

I originally set this up because we wanted to limit who used up 4D Write 
licenses. Not currently being used however.

So after they do their custom login can’t I...

just assign the admin user that logs in to the “Admin” group and everyone else 
to the "Default Group”?

Seems like that should work.

Appreciate,
John…

It is the opposite. The checkbox under Database Settings/Security allows you to 
set a 4D group that HAS access to design mode.

We create the group “Development” as the Designer, so the Administrator doesn’t 
have access to edit.

John:

Been there (many years ago) in the days of interpretive Basic. Had one client 
who loved to tinker. Since he owned the place, we had no choice but to allow 
it. But then he would go away for a couple of weeks, and they would call me 
when something did’t work. Open the code, and you could see his ‘finger prints’ 
all over the code (yep, we all have styles).

Love the compiler.

I do understand your problem.

Re: Disable close button on Splash screen windows v12

[truegold via 4D_Tech]

Hi Alan,

Thanks, I’ll give it a try.

I did realize that part of my problem - and why I need a 4D group to prevent 
access - is that some of the code is still run inside the 4D application 
process which is what also controls the splash screen. So it’s possible, even 
after hiding it, to still get into “design mode”.

So if I get the group access figured out so that only admin has access to 
“design mode” in a compiled database then they can keep their splash screen 
window.

I appreciate the code though and will test it.

John...

Re: Disable close button on Splash screen windows v12

[truegold via 4D_Tech]

Hi Robert,

I think you meant me not Jeremy.

This database - and how this admin user has managed things - goes back to 1993 
or so. The user has been able to get into “user mode”, now called “design 
mode”, reliably up until 4D 2012.

Rather than having code for everything minor change this user still prefers a 
quick and dirty sprint into “design mode”. Dangerous? Yep! explained? Yep! User 
wants to change? Nope!

That’s what I meant. But the only person who is supposed to be able to get into 
“design mode” is admin.

Hopefully that explains my ordeal.

Appreciate,
John...

Jeremy:

'Quick Edits' of what?

My databases are all compiled. The Designer can do anything, including exiting 
the splash screen, and then to user mode. Anyone else can have certain 
privileges(or most all), but they can not exit the splash screen.

Re: Disable close button on Splash screen windows v12

Hi Jeremy,

Thanks for the info.

I need to make sure that if they log in as admin then this restriction is not 
there. I have tried for years to dissuade the “power” user from going into 
“design mode” but she uses it for quick edits (as unreliable as it has 
seemingly become). Anyway...

So I need to make sure only users that are part of the “keep out” group are 
kept out.

Will this approach work?

Re: Disable close button on Splash screen windows v12

[truegold via 4D_Tech]

Hi All,

I’m asking this because I have time scheduled tomorrow to try this approach. 
But I though I’d explained and see what others have experienced using similar 
approaches.

So if I want to protect the db from a user getting into “design mode” - given 
we have rolled our own password security - can I simply do the following:

Add a 4D Group in the password editor. Is there not a checkbox to disallow a 
user into design? So if I set things up this way and then…

After the user logins to our custom PW login system immediately identify them 
as a member of this group will that work? Will that keep them from getting 
access?

Thanks,
John...

The new versions of the command use the same command name with an "Ex"
