Screen Resolution Notification

[dedndave]

which notification (message) tells us if the user changes screen resolution ?

Probably WM_SETTINGCHANGE though I'm not sure if resolution is covered by that one.

All top-level windows receive WM_SETTINGSCHANGE when any of the SystemParametersInfo values changes.
While it doesn't strictly give the screen resolution, SPI_GETWORKAREA gives the usable desktop area which should be what you're actually interested in.

WM_SETTINGCHANGE -- http://msdn.microsoft.com/en-us/library/ms725497%28v=VS.85%29.aspx
SystemParametersInfo -- http://msdn.microsoft.com/en-us/library/ms724947%28VS.85%29.aspx
