Looked at the online information, heard that it is
The class __declspec (dllexport) CButtonColor;
The class CButtonColor: public CButton

Then when I go to call
CButtonColor speed;

The class __declspec (dllexport) the name of the class;

CodePudding user response:

The class __declspec (dllexport) CButtonColor;

You can have a try, in a DLL:
The class __declspec (dllexport) CButtonColor: public CButton


And then in front of the caller added the
The class __declspec (dllimport) CButtonColor;
Of course, there are:
# pragma comment (lib, "your DLL. Lib")


Then use the
CButtonColor test;




If the wrong, don't blame me, because I've never used MFC form of DLL, the DLL, I always avoid using MFC class object...
