From this example, https://support.zemax.com/hc/en-us/articles/1500005577882-Using-ZOS-API-with-C-and-C-what-to-install, I set a break point after the line “Surface_1->Thickness = 50.0;” in Visual Studio 2017 or 2022. I expected the Visual Studio Watch window to display 50 for Surface_1->Thickness when it breaks, instead Visual Studio displayed this message “Surface_1->Thickness    operator -> or ->* applied to ‘_com_ptr_t<_com_IIID<ZOSAPI_Interfaces::ILDERow,&_GUID_774c8955_b4d3_4232_95ce_3b4cd460e8b3> >’ instead of to a pointer type”.

Question: Is there a way to display “Surface_1->Thickness” value in Visual Studio debugger window?
