What i want to do,
I want to export this class into a dll,
so other cannot view the implimentation.
I only want to provide them header file only and that dll file so they will not be able to edit this class.
Thanks.

Re: Making a DLL, How??
Main Story why am i asking this question, I use different APIs like Ogre SDK, PhysX SDK, FMOD SDK,
so what these SDK do,
1. They provide header files having extension .h, I include this header file into my project.
2. They provide a file having extension .lib, I include this file into my project like this:
Code:
#pragma comment( lib, "OgreMain.lib" ) // adding library file
3. They provide a dll file, When i compile my project it produce a exe file, when i run this exe file it demands for dll then i copy that provided dll file into my exe folder then my exe file executes correctly
they don't provide cpp files, they hide implimentation, i want to know that how they do so,
A complete tutorial that explain it all step by step.
What i know:
dll stands for Dynamic Link Libraries, they are files having similar structure like exe files. The executable code for the function is located in a DLL.
Dont Know,
But don't know the whole process of making dll and lib files.
Any tutorial link will be helpful.
Thanks.

Re: Making a DLL, How??
just create a DLL project in your ide.

Re: Making a DLL, How??
I have already many classes, is it not possible to make a dll project,
Any other solution plz.
Thanks.

Re: Making a DLL, How??
start over, create a new dll project, add your sources to it and you're done.
Hey, there's tons of documentation about how to make a dll. It just needs a bit of effort to get through it. And you might happen to learn something new. Or are you afraid of it?
