any way to use activex dll?

[nanchengjiumeng]

I have a activex dll. Register through:

C:\Windows\SysWOW64\regsvr32.exe TURING.dll

For a long time I have been calling through CreateObject ("TURING.FISR") in vbs.

vbs code:

Set TURING = CreateObject("TURING.FISR")
TracePrint TURING.Version() // "x.x.x"

I have no experience with windows api. I have tried the following code:

com::interfaces! {
    #[uuid("255A76EC-9167-4034-89DE-06CF1B9930D0")]
    pub unsafe interface IidFisrvptr: IUnknown {
        pub fn Version(&self) -> com::sys::HRESULT;
    }
}
fn main(){
   unsafe {
        let guid =
            windows::Win32::System::Com::CLSIDFromProgID(windows::w!("TURING.FISR")).unwrap();
        let clsid = com::IID {
            data1: guid.data1,
            data2: guid.data2,
            data3: guid.data3,
            data4: guid.data4,
        };
        // let ppunk: *mut windows::core::IUnknown;
        init_apartment(ApartmentType::SingleThreaded)
            .unwrap_or_else(|hr| panic!("Failed to initialize COM Library{:x}", hr));
        println!("Initialized apartment");

        // Get a `BritishShortHairCat` class factory
        let factory = get_class_object::<IClassFactory>(&clsid)
            .unwrap_or_else(|hr| panic!("Failed to get cat class object 0x{:x}", hr));
        println!("Got cat class object");

        // Get an instance of a `BritishShortHairCat` as the `IUnknown` interface
        let unknown = factory
            .create_instance::<IUnknown>()
            .expect("Failed to get IUnknown");
        println!("Got IUnknown");

        // Now get a handle to the `IAnimal` interface
        let fptr = unknown
            .query_interface::<IidFisrvptr>()
            .expect("Failed to get IAnimal");
        println!("Got Version String: {}", fptr.Version()); //  "Got Version String: x.x.x"
    }
}

get a error:

Initialized apartment
Got cat class object
Got IUnknown
thread 'main' panicked at 'Failed to get IAnimal', src\bin\turing_com\mod.rs:45:14
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
error: process didn't exit successfully: `target\i686-pc-windows-msvc\debug\server.exe 8001\` (exit code: 101)

i don't know how to get interfaces's uuid, but i got 255A76EC-9167-4034-89DE-06CF1B9930D0 here:
