I have encountered a problem that I am hoping someone can shed some
light on.
I have a multi-user A97 app. All users have a personal front-end MDE
accessing a shared back-end.
There is no specific MDW file for the app as security rules are housed
within the app itself.
On a couple of occasions, different users have launched the app only
to have the back-end opened in exclusive mode, preventing others from
being able to run the app. The absence of an LDB file precludes the
use of LDBViewer to ascertain which user has the back-end locked.
Once the user in question had been identified and exited the app,
multiple users could then launch the app with no problems.
My questions:
* how can this even happen? (i.e., a front-end causing a back-end to
be opened in exclusive mode?)
* is there any way to programatically ensure that a back-end is NOT
accessed in exclusive mode?

When you re-link, one of the options is 'exclusive'. If you
use the wizard, make sure the checkbox is cleared. If you have
DAO code to relink, use 0 (zero) as the relink option instead
of dao.dbAttachExc lusive
To prevent exclusive access, open the BE database, goto security,
SCROLL UP from tables TO DATABASE, and remove the exclusive
access permission from the 'admin' user.

Hello,
I realize that this may not be the best place to ask this question,
through the application is asp.net. I also realize that questions
about disabling the back button are generally met with derision, so
let me explain:
(1) The site is actually a web-based application, not a "web site" per
say, and is not accessable by the public. It is an application used
internally by the company I work for, though it accessed by employees

I added a 'Back' button to my page, and wrote 'OnClick'
code something like this:
Response.Write("<script>history.go(-" +
iDepthIndex.ToString() + ");</script>");
But, it dosnt work! Effect is that browser navigates to
desired page as expected and go back from where it
started! But, the 'Back' button on browser works normaly.
I dont get it!!??

I have two dropdown lists. Both have autopostback set to true. In both
dropdowns, when you select an item from the list, it redirects to the Value
property of the dropdown. Nothing fancy.
Let's say you select 1 of the items, and are properly redirected. You press
the back button. I have three servers providing two different
functionalities:

still selected.

I have an asp.net page. It accepts data through on form fields and
includes a submit button. The page loads up and you fill out some
stuff. The submit button posts the page back to the server. The
button code detects an entry error and sends the page back to the
user. This all works.
However, if the user presses the Back button at this point, we go back
and all the form values are...

Hi all,
I'd like a page to be excluded from the back button history, that is,
when a user hits their browser's back button, it never backs into this
particular page.
Can anybody please tell me how to do this?
I thought perhaps there would be some kind of special meta tag that
says something like "exclude me from browser's history", but have been

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
