应用程序如何在 Windows 10 上检测缩放和监控布局变化

Question

I have application that can control other application position. On start it get current monitors' layout and dimensions. They are used to calculate the proper position of the window on the secondary monitor with the different (not default) scaling. But when the user updates the monitors' layout application keeps using initial values.

is there any possibility to capture scaling change or monitors layout change?

Answer 1

You need to receive and handle the WM_DPICHANGED and WM_DISPLAYCHANGE messages.

I suggest you read MSDN's documentation about High DPI Desktop Application Development and Multiple Display Monitors for more details.
