How can I call a C ++ win32 dll from another c ++ win32 console application

Question

What is my main problem: I can write C ++ dll using VC ++. Now the dll is present in the Debug folder.

How can I use my DLL in another C ++ console application. How to add a link or associate a DLL with an application.

Another point. Creating a DLL, the VC ++ wizard gives me the opportunity:

• Empty dll project
• Simple dll project
• Dll that exports some character

Now, according to the article from CP, I used the third option. (Failed to complete because the DLL was used by the MFC application, some of which are slightly advanced at this point in time)

Should I always choose the third option? What do the other two options mean?

Answer 1

Not quite sure about your questions:

It doesn’t really matter which option you use, it’s just a matter of what the wizard does for you; if you use the third option, the wizard creates a bit in your header file that looks like this:

#ifdef TEST_EXPORTS
#define TEST_API __declspec(dllexport)
#else
#define TEST_API __declspec(dllimport)
#endif

, , DLL TEST_EXPORTS , TEST_API dllexport, . , TEST_API dllimport, , DLL. #define .

/ DLL, : a) __declspec (dllexport) [ ] ) .DEF

, DLL .exe .lib, DLL.
