<p>I have a WTL app running and would like to know when the screen resolution has changed. The most likely candidate would appear to be <code>SPI_SETWORKAREA</code> sent via the <code>WM_SETTINGCHANGE</code> message but I wondered if this is the correct message to use. This has to work on XP and Windows 7.</p>

<p>WM_DISPLAYCHANGE is the better mouse trap.</p>

Screen resolution change notification message?
