Thanks to Robert Brewer, I got enough insight into logging to make it work....
Now I have another issue: file locking. Sorry if this is a very basic
question, but I can't find a handy reference anywhere that mentions this.
When a logger opens a log file for append, is it automatically locked so
other processes cannot write to it? And what happens if two or more
processes attempt to log an event at the same time?
Here's my...

Our solution contains multiple projects, on some of the
larger projects it appears IntelliSense is locking the
output DLLs and we get the dreaded "Could Not Copy
Temporary Files to the Output Directory" error.
We've followed the guidance provided in this KB

Hi all,
Over the years, I have had to keep dealing with the same Access restriction -
that you can't update a table in a statement that joins it to another
non-updateable query or employs a non-updateable subquery. I run across this
problem again and again, and yet I've never come up with a single, universal
work-around.
I'm wondering what other people here are doing.

I have a function which clears out a temporary table and then fills it
with values from a recordset. One of the table fields is indexed with
no duplicates. Very rarely - almost enough to ignore it - two users
will call the function at once causing one of the functions to attempt
to update the table with duplicate values.
Is there a way to lock the table to prevent this happening?

Hi,
When you open a file for writing/appending with open() or fopen(), and
you have multiple applications that might want to write to the same file
at the same time, could that cause weirdness in the file ?
do i have to add manual file locking, or does open()/fopen() provide
file locking ?
Thanks,

Hi All,
I am working on the situation where 2 different
Process/Application(.net) tries to open file at the same time....Or one
process is updating the file and another process tries to access it,
it throws an exception.
How to solave this problem? So second process can wait until first
process completes its processing on the file.
Thanks in advance

Hi,
I am re-writing part of my application using C#. This application starts
another process which execute a "legacy" program. This legacy program writes
to a log file and before it ends, it writes a specific string to the log file.
My original program (MKS Toolkit shell program) which keeps running "grep"
checking the "exit string" on the "log files". There are no file sharing
problem.

Here is the situation: I wrote a VB programm, which stores all the
information in a single Access database file using jet engine. It
worked well, however one of my customs reported that there was some
problems with this programm. I checked, the log files showed that the
database was corrupted.
The customer told me that there no 'illegal' operation such as pull out
the plug, or kill the programm via task manager...
So is there any...

Hi,
Trying to open a file for writing that is already open for writing
should result in an exception.
It's all too easy to accidentally open a shelve for writing twice and
this can lead to hard to track down database corruption errors.

I am trying to get multiple threads to lock specific regions of a file.
However, since each thread has the same PID, it appears that a lock by
one thread does not block another thread from the same process.
How does one maintain file locking between sibling threads?

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:
