Why is my MFC DLL project missing many interfaces when adding EXCEL library? For example, _Application, _Workbook, _Worksheet, Workbooks, Worksheets, Range... None of these, so I can't use them right now. How can I solve this? Please help me. Thank you. Is there any MFC DLL using EXCEL com interface related documentation tutorial? If anyone has one, please send it to me. Thank you!vs

    Hi,

    VS2022 can add these interfaces, but not 2019

    Glad to know that VS2022 and Microsoft Excel 16.0 Object work for you. For problems about VS2019, I found a fix for add class:https://developercommunity.visualstudio.com/t/MFC-Long-list-of-errors-generated-when/1588036 Please consider using VS2022 instead of VS2019. Best regards, Minxin Yu
