OpenGL Rendering

[bitshifter420]

Which is correct, ive seen it done both ways,
i would say the latter is proper, am i wrong?

In the window message procedure

WAY_1

case WM_PAINT:
BeginPaint(...);
RenderScene(...);
SwapBuffers(...);
EndPaint(...);
return 0;

WAY_2

case WM_PAINT:
BeginPaint(...);
EndPaint(...);
RenderScene(...);
SwapBuffers(...);
return 0;

ps: RenderScene() is a user defined function,
also im using HDC of my own, not (HDC)wParam
because of the custom pixel format and HGLRC in use.
