Hi all,
I am facing problem configuring a counter, which increments for every Logging
event. My counter increments for Every logging event as supposed to do. But it
is not resetting to zero and start counting for each user start to access
application. It is starting from the count it is counted for logging events
for the previous user.
I followed some sample code i got from the internet. Here is the code sample
code. Conter should start from zero and count the logging events for every
user, since i need to log the counter value and logger text inside the data
base.
Any Help will be appreciated
