Thread: Need Help on Windows Animation, PLEASE!

Yesterday i took an example program from Bloodshed Dev C++ 4.9.9.2, which by the way was pretty good, and tried to encapsulated in 2 classes, Window class and Ball class. I am almost sure i have everything typed down correctly, yet i keep getting errors on "undefined reference". I'll post all files of code below for anyone to examine them and see what's the problem:

WinClass.hpp

Code:

       int Create_Window(char ClassName[ ], char WindowCaption[ ], HINSTANCE hInst, int wndWidth, int wndHeight);

    private:

And these are the linker errors i'm getting in both Dev C++ and Code::Blocks:
Here Code::Blocks;

Code:

Please read this and apply if you have a solution.
By the way, my bitmaps are in the same directory as the project.

Thanks in advance!
