WM_SETTINGCHANGE top-level constant Null safety

int const WM_SETTINGCHANGE

A message that is sent to all top-level windows when the SystemParametersInfo function changes a system-wide setting or when policy settings have changed.

Applications should send WM_SETTINGCHANGE to all top-level windows when they make changes to system parameters. (This message cannot be sent directly to a window.) To send the WM_SETTINGCHANGE message to all top-level windows, use the SendMessageTimeout function with the hwnd parameter set to HWND_BROADCAST.

Implementation

const WM_SETTINGCHANGE = WM_WININICHANGE;
