GetDpiForSystem function (winuser.h)
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.
