if (!user_driver->pUpdateDisplayDevices( &device_manager, TRUE, &ctx )) {
static const DEVMODEW modes[] =
{
{ .dmFields = DM_DISPLAYORIENTATION|DM_BITSPERPEL|DM_PELSWIDTH|DM_PELSHEIGHT|DM_DISPLAYFLAGS|DM_DISPLAYFREQUENCY|DM_POSITION,
The DM_POSITION flag is only used for the current mode. For available modes, they have no position obviously. Add a space before and after the |. And is it really necessary to add 6 modes? Not that there is anything wrong with it.
