This is really a question that only programmers (.NET programmers) may be able to answer.

I have written the following code, designed to ascertain the number of icons on the main desktop.
It works provided the icons are not stored in a "Fence" placed on the desktop via the program "Fences". 

Does anyone know how to change the code so that the number of icons
(both positioned in different Fences and "floating" outside of a fence) is returned? 

The reason for the code? Under Windows 10, if you place more than 51 items on your desktop (including shortcuts/folders stored directly into a desktop folder) the functionality of the "Browse" window when creating shortcuts is "broken". (See my video: https://youtu.be/kqhk-jH2b8U)

I do not expect anyone will be able to answer this, but I keep my fingers crossed.
(The code is VB.NET by the way)
