DLL

 

I'm looking to create a dll but I'm not to sure of each step, I've read the two articles on dlls that mql5 has but I can't pin point each step. Example, you can copy the .dll file to mqls library folder or add the path to vs post build events? What about the import export header file that's built with the dll in visual studio? Is that added as an include to mql? Would mql take .h header file?
