How do you use DLLs?

[biot023]

Hallo.
I have a dll & an .obj file & a .lib file, all created in VC++, unfortunately.
I have converted these to OMF (using Borland's utility), and that seems to have gone fine.
But I now have no idea what steps to take to use the dll in a Builder application.
I've included the .lib and .obj files in the project, but the compiler can't see the implementation of any of the functions.
I'm on a really tight timeline, or I wouldn't post for help before doing more research.
Thanks for any & all help,

You also have to include the .h files that define the functions. They should be included with the other files.

Yeah, I have included the .h file - I thought that once I'd done that, all I had to do was add the .lib file to the application.
This didn't work (it couldn't see any implementations), so I added the .obj file as well.
But it still couldn't see any implementations.
So I browsed to the dll itself in the packages bit of the options, and still no implementations.
I am rather lost.

Try using LoadLibrary and GetProcAddress (implicit linking ,i think, its called).

As Supernat03 mentoided you have to use .h file for static linking where you have to write this:
1.Include .Lib in your project
2.Create .h file with declaration of DLL functions:

__declspec(dllimport) int F(int n);//function in your DLL
__declspec(dllimport) void F1(double);
.......

3.Include this .h file in your files where you want to use
DLL functions

That's it all.Simple Is'n it?
