[senatin 0]

I found this tutorial script about dll but is written in other code
I want to know what it return or throw when it fails.
Im starting to learn calldll and its other related code.
Can you please help me convert this code to autoit

class MSC_Helper {
static _ := MSC_Helper.InitClass()

InitClass() {
    if !A_IsAdmin {
        Run *RunAs "%A_ScriptFullPath%"  
        ExitApp
    }
    this.LoadDll()
}

LoadDll() {
    if A_Is64bitOS {
        dllFile := (A_PtrSize=8) ? "64\mscon64.64.dll" : "64\mscon32.32.dll"
    } else {
        dllFile := "32\mscon32.dll"
    }

    if !this.hModule := DllCall("LoadLibrary", "Str", dllFile, "Ptr") {
        if !FileExist(dllFile) {
            throw, dllFile " not found."
        }
        throw, "LoadLibrary failed. DllFile is " dllFile
    }
    this.dllFile := dllFile
}

UnloadDll() {
    DllCall("FreeLibrary", "Ptr", this.hModule)
}

}

Thank you in advance.
