This Module is one of the parts of my project. There are still a lot of good reasons to use .DLLs. Later you'll see that the MFC library has its own method of loading resources by searching various modules in sequence. The dynamic linking process then builds a table that connects the client's calls to the function addresses in the DLL.
Use code such as this: HINSTANCE hInstResourceClient = AfxGetResourceHandle(); // Use DLL's instance handle AfxSetResourceHandle(::GetModuleHandle("my_dll_file_name.dll")); CString strRes; strRes.LoadString(IDS_MYSTRING); // Restore client's instance handle AfxSetResourceHandle(hInstResourceClient); You can't use AfxGetInstanceHandle() instead You simply tack "_declspec(dllexport)" onto the beginning of your function prototype: __declspec(dllexport) int SomeFunction(int); If you are making an MFC regular .DLL which will be used by a client application written When you compile your .DLL, the compiler creates two important files: the .DLL file and the .lib file. Therefore, for an MFC extension .DLL to work, both the extension .DLL and the client program must dynamically link to the same MFC code library .DLL, and this .DLL must be https://msdn.microsoft.com/en-us/library/9se914de.aspx
Build the project and copy the DLL file. When it exports a class, the client will be able to create objects of that class or derive new classes from it. Figure 2: The only step 1 of 1 DLL project.

When Windows loads the DLL, it calls this function, which first calls the constructors for global objects and then calls the global function DllMain(), which you're supposed to write. There's only one special thing you must do.

In Project Settings -> Link -> Library/Modules add Debug/ProjectName.lib. First, a .DLL built with one brand of compiler may not be compatible with a client application built with a different compiler. Fixes and other modifications would only have to be done one time.
Because the MFC library is statically linked into each DLL or EXE, there is no question about which version you have.API LimitationsSome MFC functionality does not apply to the DLL version, If your program includes an extension DLL and your EXE needs a resource, the search sequence is first the EXE file, then the extension DLL, and then the MFC DLLs. Table 2. If you statically link to the MFC code library, your .DLL will incorporate within itself all the MFC code it needs.
These decorated names are the long names the compiler invents based on class name, function name, and parameter types. Go to the class view, right click on “MyDll classes” and choose “New Class”.
