GetDpiForSystem function (winuser.h)

  • Article

Returns the system DPI.

Syntax

UINT GetDpiForSystem();

Return value

The system DPI value.

Remarks

The return value will be dependent based upon the calling context. If the current thread has a DPI_AWARENESS value of DPI_AWARENESS_UNAWARE, the return value will be 96. That is because the current context always assumes a DPI of 96. For any other DPI_AWARENESS value, the return value will be the actual system DPI.

You should not cache the system DPI, but should use GetDpiForSystem whenever you need the system DPI value.
