WM_DEVMODECHANGE
The WM_DEVMODECHANGE message is sent to all top-level windows whenever the
user changes device-mode settings.
WM_DEVMODECHANGE
lpszDev = (LPCTSTR) lParam; // address of device name
Parameters
lpszDev
Value of lParam. Points to the device name specified in the WIN.INI file.
Return Values
An application should return zero if it processes this message.
Remarks
Windows NT: Calls to functions that change the WIN.INI file may be mapped to the
registry instead. This mapping occurs when WIN.INI and the section being changed are
specified in the registry under the following keys:
HKEY_LOCAL_MACHINE\Software\Description\Microsoft\
Windows NT\CurrentVersion\IniFileMapping
The change in the storage location has no effect on the behavior of this
message.
