I'm experimenting with GDI+. Say I have a box and want it to move across the screen on a keypress. Do I have to clear the screen and redraw everything everytime I want to move the box? Or is there a way to just change the coordinates of the box?

Ok, so I figured out how to move objects, but the screen flashes and it looks very bad. Help?

Are you using WinForms? If so, turn on the DoubleBuffered property (select your form in the designer and select the cell next to DoubleBuffered on the right hand side, set it to true). I'm not sure how to do the equivalent in other platforms.

I'm not using MFC. I'm creating the window myself with pure code.

Check out this article: http://www.codeproject.com/KB/cpp/DoubleBuffering.aspx
I've not done much in the way of Win32 API so I can't help any further than that, but this is the general concept of what you need to do.
