VB6SP6, VBCCR17, Win10 (latest) & Dark Mode acitvated

Does anybody know how to activate the windows 10 dark mode for an vb6-app?

I already set the background color of the app window myself and change the background color of the most controls but i dont know how change the color of the window title bar or the scrollbars.

I guess there must be some windows theme API that can activate the dark mode for the window and maybe the controls too?
