How to know if a device can be disabled or not?
- by user326498
I use the following code to enable/disable a device installed on my computer:
SP_PROPCHANGE_PARAMS params;
memset(¶ms, 0, sizeof(params));
devParams.cbSize = sizeof(devParams);
params.ClassInstallHeader.cbSize = sizeof(params.ClassInstallHeader);
params.ClassInstallHeader.InstallFunction = DIF_PROPERTYCHANGE;
params.Scope = DICS_FLAG_GLOBAL;
params.StateChange = DICS_DISABLE ;
params.HwProfile = 0; // current profile
if(!SetupDiSetClassInstallParams(m_hDev, &m_hDevInfo,¶ms.ClassInstallHeader,sizeof(SP_PROPCHANGE_PARAMS)))
{
dwErr = GetLastError();
return FALSE;
}
if(!SetupDiCallClassInstaller(DIF_PROPERTYCHANGE,m_hDev,&m_hDevInfo))
{
dwErr = GetLastError();
return FALSE;
}
return TRUE;
This code works perfectly only for those devices that can also be disabled by using Windows Device Manager, and won't work for some un-disabled devices such as my cpu device:
Intel(R) Pentium(R) Dual CPU E2160 @ 1.80GHz.
So the problem is how to determine if a device can be disabled or not programmatically?
Is there any API to realize this goal? Thank you!
