I'm using visual c++ everything compiles fine I just need to be pointed in the right direction when i run the program and maximize the window or do any resizing at all the buttons stay in same position and the image won't resize. thanks for the help code is below.

Handle WM_SIZE (http://msdn.microsoft.com/en-us/library/ms632646.aspx) message in the main window and use MoveWindow (http://msdn.microsoft.com/en-us/library/ms633534(VS.85).aspx) or SetWindowPos (http://msdn.microsoft.com/en-us/library/ms633545(VS.85).aspx) function to move and/or resize its child windows.

If you need to move a lot of windows it might be useful to use DeferWindowPos (http://msdn.microsoft.com/en-us/library/ms632681(VS.85).aspx) to move/resize everything at ones.
