In writing a small tool recently met the following problems:
One, vs2019 getobject (" E: \ 123. XLSX ") when acquiring the form, you will be prompted "can't create activeX controls, and also changed the dcom components inside excel access, but still can't solve,
Second, vs2019 getobject (, "excel. Application") can't get to have open the excel spreadsheet,
The above is my problem, but in vs2010 or vs2017 environment, these two problems don't exist, all can be normal, but I still want to use 2019, a great god, please help solve, thank you very much,
