Windows Form? to work with codes

[dannyboy997]

i was wondering how do you work with a windows form,

-for an example if you want to have a progressbar in the window how do you control that object with c++ code,

so functions, classes, what do i need to do, i have looked online but i can't find anything. i know c++ very well but the only thing i don't know is working with windows and controling them with the code.

i am using visual C++ 2008 to create the window and write the codes!

Thanks...!
