Looking for experienced C++ developer who can explain one specific difference between three similar programs in my project. All three programs read a text file with control characters, put the file into a listbox which allows viewing and then printing. I will call them programs 1 2 and 3.
Program 1 is the original, which does all 3 things correctly, was written 20+ years ago using Visual Studio.
Program 2 and 3 are newer versions of the original, but with many more viewing and selecting capabilities. They were written in 2022 using Visual Studio 2017. At the time they were written I was under the impression the printing routine was taken from program 1.
I recently discovered there are two reports my system generates that programs 2 and 3 are not printing correctly.
I would like to isolate this issue and fix it.
