DLL and MDIChild - explainig the code

I've been searching within this forum for a topic that has already been discussed. The topic revolves around how to load an MDI child from a DLL.

Some individuals have mentioned that mdiextender (which is a paid and outdated solution) can accomplish this, as well as the mdiActiveX control, which has its 1.0.3 version source code available on GitHub.

I attempted to use mdiActiveX, but unfortunately, it didn't work for me.

Then, just two days ago, I came across this thread:

Within this thread, a method is described that achieves the same goal. However, even after reading it multiple times, I'm still uncertain about where to place the provided code.

Could someone kindly provide a detailed, step-by-step explanation of what needs to be done?


regards,
Angelo.
