Hi,
I was wondering the best and fastest way to determine how many lines are
in a log file.
At the moment I am simply doing a StreamReader.Re adLine and incrementing
a counter until I reach the end. Is there a better way??
Cheers,
Craig

Otis,
Thanks for your advice.
Justin suggested a similar method.
I think that estimating the lines int file is the best and quickest way.
I am reading unix server syslogs in to a database. Some times the log
files are 3 Gb in size before they reach me.
Cheers,
Craig

Craig,
Here is a simple way to do this. Not highly technical, but:
1. Find the size of the file.
2. Read the first 1000 lines of the file to determine the average
length of a line, including the line terminator.
3. Divide the file size by the line size and add one, if the last line
was not terminated. To determine this just seek the end of the file
and look at the last character in the file.
If the line length is fixed you will have your exact answer. If not
then you will have a pretty close estimate.
Question: What is the purpose of knowing the number of lines in the
log?

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:

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,...
