How an application can check if a PCI device is disabled/enabled (done from Device Manger) ?

    If you are using C# then WMI is very easy to use and the Win32_SystemDriver class will indicate a State of 'Stopped' for a disabled device.

    Thanks Mark. Mine is a C++ application.

    Then unfortunately you can use the devcon sample code to do this the hard way.

    You can still use WMI in C / C++, but the SetupDI API is the standard way.

    You can, but if you ever have had the misfortune to have to do this, it is not something you are likely t5o recommend.

    I have never used WMI from any language other than C. Like all COM interfaces it is much easier to use in C++ than in C. The Setup DI APIs are much simpler I think.

    In my shop, we use a lot of C#. Probably the most used of any language. But I have had the misfortune to have to use a lot of stuff
