What trigger the Program Compatibility Assistant when running program

Question

Even the most simple hello world dialog can cause it. (the code is from Programming Windows®, Fifth Edition) After the exe closed, the PCA pop out, and it will no longer pop out again. But if I change the filename of the exe, it will pop out again.

So I am very curious which make theh PCA act, and how to avoid it act anymore. In an another word, I don't want my program trigger the PCA when first running in the other computer.

Answer 1

Probably you should avoid obsolete things that have modern alternatives in current Windows. Check the revised source code, for example: https://github.com/recombinant/petzold-pw5e.

Or show your current unadjusted code.
