May I know if your problem has been solved? It will be better to provide a minimal reproducible example.

I suggest you look into using an MFC Extension DLL to export your dialog classes so that they can be shared by MFC applications. You may also find the discussion at which-is-the-best-way-to-use-an-mfc-application-as.html to be informative and it also contains a link to an MFC Extension DLL sample that I provided for that questioner.

I have included the library header file in application file and i used DLLIMPORT , but when i call the imported function and run the application it crashes.

what have i done so far: 1.In library file i have exported function which will create window using Create(dialog,obj);
2.Then i have imported this function in application i called the function
3.but when i run application it crashes

use standard dlls with standard C types. if you can't, check https://stackoverflow.com/questions/22797418/how-do-i-safely-pass-objects-especially-stl-objects-to-and-from-a-dll
