I am using Dev-C++ 4.9.8.0. I tried to make DLLs in Dev-C++.
Can anyone with kindness tell me where can I get the help materials on making classes in a DLL and use the member functions in my executables?

I found many materials spoke on the functions in DLL but few of them spoke on the member functions and classes in DLL.
Although the platform gives the skeleton of a C++ DLL,i.e. dllmain.cpp, dll.h,I can not understand it.

The help files in Dev-C++ did not explain it explicitly.

Maybe a step_by_step turial is useful.
I know that is not quite appropriate to ask such question in this area.

But after several days of asking problems, I found there are lots of experts here. And I am just a new comer in programing.

Does someone know the format of DLL made from Dev-C++ ?

Coff or omf ? Can the DLL be applied by Borland C++ builder 2009?

If not, how can I handle it?

Can the DLL be compatible with Visual C++?

Thanks a lot.
