Hi, I'm pretty new on C++.

In a Windows Forms project I need a bitmap slide bar and a bitmap pointer to the bar.

The bar is like this: link.

Each horizontal position of pointer must return an number related with minimun and maximum possible position, that coincide with the start an end of the bar. So that even if the desing of the bar is wrong, the pointer returns the correct relative value.

Another words: the bar is only background. Ok?

I tried explain step-by-step becouse I'm brazillian, and wanna be understood

Thanks
