The window handle of the masked edit control.

The return value is the current DPI - 96 at 100% scaling, 120 at 125%, 144 at 150%, 192 at 200%.

Comments

On a Per-Monitor v2 aware host, the value changes as the window moves between monitors with different scale factors, and the SFTMASKN_DPI_CHANGED notification is sent. On System-aware or Unaware hosts, the value is fixed for the process lifetime. See Per-Monitor DPI and Scaling.
