I was wondering if I can check to see if a file is open?
Specifically, is there any way I can code Access to check to see if a
text file (datasource.txt to be specific) is open, returning a true
value and creating a loop? Then, once the file closes, return a false
value and closing the loop?
I need to run a batch file using Shell() and then run queries based on
the text files that this batch files create. The catch is that the

Hi,
What is the most easy way to check on EOF while reading a
binary file with all integers ?
In lot of examples the read data are first stored in a
string, and afterwards the string is checked on *null*
value, but that does not work for binary files.
Like this ...

Newbie question:
I'm trying to determine if a file physically exists regardless of the
permissions on it
Using File.Exists() returns false if it physically exists but the
process does not have the necessary permissions.
One hack could be to check for length and that would throw a
FileNotFoundException ...but there is got to be a better way!

We hear very often in this discussion group that
bounds checking, or safety tests are too expensive
to be used in C.
Several researchers of UCSD have published an interesting
paper about this problem.

My own initial reaction was that, if I saw the latter in code, I'd say
the programmer is playing games trying to impress with funky features. I

Greetings!
I've just started learning python, so this is probably one of those
obvious questions newbies ask.
Is there any way in python to check if a text file is blank?
What I've tried to do so far is:

Hello,
I read some files name from a directory and then I put these name in a
list. I will check whether it is empty or not, and I would do it with
an exception. With if statement it is very simple:
If list_of_files != "" : # this can be if list_of_files !=
:
get the files

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,...
