Use the CheckRadioButton call in the WM_INITDIALOG message processing
for your dialog box.

If you are copying them with GetBitmapBits or CopyBitmap, no.  In 
general you need to lock any time you get a long pointer to a
memory address other than your own data segment during the processing
of a single message.

You do a CreateDialog instead of a CreateWindow call in your WinMain
routine.  Note that you need to allocate extra space in your window
structure by setting wndclass.cbWndExtra = DLGWINDOWEXTRA before you
call the CreateDialog routine - otherwise you will corrupt memory.

All of this is explained in much more detail in Petzold's book
(Programming Windows), which is an excellent introduction to Windows 
programming.  Trying to learn Windows programming without using it 
(or a similar book, though Petzold is probably the best of the lot) 
is like trying to program with both hands tied behind your back.  
Heavily recommended.

Good luck -
