How To Make Bitmaps on Menus Transparent in C++ Win32

This Tutorial Follows on from a previous Tutorial that I had.
I recently came across someone who wanted to make their bitmaps
Transparent for his Menu’s and no matter how much I helped him
He still wasn’t getting it. In fact he kept saying bitmaps are ‘ugly’
And icons were better.
Which surprised me as every format is eventually internally transformed to a bitmap by Windows.
But the truth is you can make bitmaps transparent if you want.
This is what we will do in this Tutorial so no matter the color of your menu
You will see transparency…. latest front page
