I have a client using IE with a .net web application who
is getting a Concurrency Violation whenever she tries to
update certain records in her database.
The strange thing is that I can open up multiple instances
of IE an go to the same page and update the same record
from all 3 instances at the same time as she is getting
the error.
The update is being done using a dataadapter and dataset

Hi All
I'm having problems getting my data adapter to throw a concurrency
exception with an INSERT command. I want to throw a concurrency
exception if an attempt is made to enter a row into tb_table when a
row with the same int_UID already exists in there.
Here is my stored procedure:
if not exists (select int_UID from tb_table where int_UID = @aint_UID)

With respect to my (now not so recent) thread on Concurrency, I would like
to run my idea past you gurus to see if its a runner. First, a brief recap:
I have a single user system (one user, one copy of the software, one copy of
MSDE, one machine) that I wish to convert into a multi-user/single database
networked system. The problem I had was that a lot of information is
fetched from the database and cached in the client program (the...

anyone please help, i am developing and application that uses the update
method of dataadapter (select, update, delete command was set by issuing
the OleDbCommandBuilder)in updating the database. using this method
readily answers the concurrency issue. however, i always read from
various posts that is is best to use stored procs with dataadapter. if i
use this approach, how will the concurrency issue be taken care of?
please provide...

Hi NG,
I am looking for an opinion here. I am new to C# and SQL, being an old
COBOL hand. I have started into a conversion of an old COBOL ERP system. I
have a number of functions working now and it is time to decide how best to
deal with the issues of concurrency. The old COBOL programs used record
locking to prevent concurrency errors and that logic is already "on the
shelf." Most C# books and articles I have seen use the default...

Dear NG,
I was about to "improve" concurrency checking with a Timestamp when I
discovered
that my current code is not working. After about a day of beating my head
against the wall, I am turning to the NG in hopes that someone can spot what
I am doing wrong.
Key to this technique working is the SQL UPDATE statement. It is designed
to fail

Hi,
I'm thinking what will happen if two users access a page at the same
time. If there are any local variable in the page, will this cause
concurrency problem?
Simarily, if this page need to call some functions, say
logic.doSomthing(), and the class logic is a singleton (for
simplicity), will there be problems?

Hello everyone!
I've been reading a great book on SOA called "Enterprise SOA" and
found that it answered many questions. However, there's one particular
scenario (involving
business-rules) that I'm not sure how to implement under optimistic
concurrency control.
Let's use a Phone-book in our scenario. We can break this down into

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
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,...
