QueryInterface -- NewB

How do I do this in Python?

hres = pObj->QueryInterface (IID_MyIntf1, (void **) &piMyIntf1);

piMyIntf1->QueryInterface (IID_MyIntf2, (void **) &piMyIntf2);

piMyIntf2->SomeMthd(args) ;

Also, how do I call/manage smart pointer interfaces?

Thanks.

I am getting an error when trying to use an ADODB.Recordset that was passed from a VB6 application to a VB.Net class library using COM Interop. I am running this on WinXP SP2 using the .Net Framework 1.1 and MDAC 2.8 SP1.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
