Sorry for not being clear. I have tried including shlobj_core.h, but it did not resolve the problem. The problem is that IActiveDesktop is not recognized as a valid symbol/class. So, despite including the noted header files - wininet.h first, followed by shlobj_core.h and/or shlobj.h, the compiler (the latest version of VS 2019) generates an error that IActiveDesktop is an unidentified class: "Identifier "IActiveDesktop" is undefined."
