Hi
I'm writing a commercial program which must be reliable. It has to do
some basic reading and writing to and from files on the hard disk,
and also to a floppy.
I have foreseen a potential problem. The program may crash
unexpectedly while writing to the file. If so, my program should
detect this during startup, and then (during startup) probably delete the
data added to the file and redo the writing operation.

I think the .NET framework is great!

It only saddens me that the new Microsoft still doesn't under stand there own rules when it comes to file paths.
A lot of Microsoft installers for example, and also installers of other companies, do not work because they handle paths in the following manner:

I have a repair and backup database routine which runs when a user closes
down my application.
It works fine in my development machine, but breaks on a client's at the
following line:
If Dir(strLDB) <> "" Then Kill (strLDB)
where strLDB is the path to the ldb file.
The client advises that the ldb doesn't lurk after the program closes.
Any ideas?

I am downloading a GIF file(as a mail attachement) with this file

On Saturday, our database machine locked up hard on us due to some
faulty hardware. Since then, we have been getting messages like this:

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,...
