SetupDiChangeState function (setupapi.h)
The SetupDiChangeState function is the default handler for the DIF_PROPERTYCHANGE installation request.
WINSETUPAPI BOOL SetupDiChangeState(
[in] HDEVINFO DeviceInfoSet,
[in, out] PSP_DEVINFO_DATA DeviceInfoData
A handle to a device information set for the local computer. This set contains a device information element that represents the device whose state is to be changed.
[in, out] DeviceInfoData
A pointer to an SP_DEVINFO_DATA structure that specifies the device information element in DeviceInfoSet. This is an IN-OUT parameter because DeviceInfoData.DevInst might be updated with a new handle value upon return.
The function returns TRUE if it is successful. Otherwise, it returns FALSE and the logged error can be retrieved by making a call to GetLastError.
SetupDiChangeState changes the state of an installed device.
The caller of SetupDiChangeState must be a member of the Administrators group.
If you specify the DICS_FLAG_CONFIGSPECIFIC flag in the SP_PROPCHANGE_PARAMS then you must fill in the HwProfile field. A value of zero for HwProfile indicates the current profile.
To enable/disable a device in the current hardware profile, set the DICS_FLAG_CONFIGSPECIFIC flag in the SP_PROPCHANGE_PARAMS. To enable/disable a device globally, such as in both the docked and undocked hardware profiles, set the DICS_FLAG_GLOBAL flag.
This function does the following:
Callers of this function should not specify DICS_STOP or DICS_START in the SP_PROPCHANGE_PARAMS. Use DICS_PROPCHANGE to stop and restart a device to cause changes in the device's configuration to take effect.
If DI_DONOTCALLCONFIGMG is set for a device, you should not call SetupDiChangeState for the device but should instead set the DI_NEEDREBOOT flag.
