ClearType on\off

WM2003SE

I create programm - for hardware button. Press - ClearType on or off realtime.

But GUI it is not updated. When I use Setting-Control Panel - Screen, GUI is
updated real. How to me to make, that the interface was updated?



HKEY hKeyN2;
int rc;
DWORD dwDisp;

rc = RegOpenKeyEx (HKEY_LOCAL_MACHINE, TEXT ("System\\GDI\\CLEARTYPE"), 0,
KEY_QUERY_VALUE, &hKeyN2);
RegCloseKey( hKeyN2 );

if (rc == 0)
{

RegDeleteKey(HKEY_LOCAL_MACHINE, TEXT ("System\\GDI\\CLEARTYPE"));
}
else
{
RegCreateKeyEx (HKEY_LOCAL_MACHINE, TEXT("System\\GDI\\CLEARTYPE"), 0,TEXT
(""), 0, 0, NULL, &hKeyN2, &dwDisp);
}

Have you tried broadcasting a WM_SETTINGCHANGE message after the change?

I have SendMessage(HWND_BROADCAST, WM_WININICHANGE, 0xF2, 0);
. Does not work. Which message and how to send?
