Hi there,
This part of the code simple means to trap error no. "2147467259 ", in VB error no. "0" simple means there is no error at all, the code is written to prompt an error message when "Run time error -2147467259" occurs, hope u understand.. :)

I have read in Bjarne Stroustrup that using malloc and free should be
avoided in C++ because they deal with uninitialized memory and one
should instead use new and delete.
But why is that a problem? I cannot see why using malloc instead of new
does not give the same result.

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,...
