Re: Windows DPI settings

System Metrics
Microsoft® Windows® provides a number of system metrics that you should use to eliminate assumptions about the user’s system. GetDeviceCaps() can be used to obtain a display’s DPI (pass in LOGPIXELSX or LOGPIXELSY for the second parameter). GetSystemMetrics() and SystemParametersInfo() provide sizes for nearly every graphical element in Windows, from the width of a three-dimensional border to the size of a small icon. One of the less obvious metrics is the minimum line thickness (pass SM_CYBORDER or SM_CXBORDER to GetSystemMetrics). At very high DPIs, a one-pixel-wide line is nearly invisible.

Hi,
is there any way how can I get the current user windows DPI settings?
We're writting some mapping software and we need to know if the user
changes the DPI for scale calculations.
Thanks
Jan
