Question

I try to ad an existing class to an SDI MFC application by right click on project, add existing item and after finding the class clicking OK. However, when I try to include this file by #include “Employer.h” the #include is by red color underlined and I get the message:
“Cannot open source file”. Do I omit something that causes this problem? When I remove the class and try to create a new one and copy-paste the existing code I receice the message: “Object Employer already exists”. What should I do to add an existing class to an MFC application?

Answer 1

Make sure that Employer.h is in project directory, or in one of “additional include files” directories.
