opengl program as win API menu item

Boy im so happy;

Well i did it and it works fine.
choose one menu item = opengl graphic.
choose one menu item = close opengl window.
and back to the main window.no peekmessage .no exclusive
opengl window.

now i havent initialized the rotation yet ,because i want to ask you the best possible root to go about it;

timer procedure or another way to mimick the continous
style of peekmessage through my normal window procedure;

my questions if you be patient with me are:

1-am i naive or can i use this style to render a small simple game using opengl in my regular window?

2-is the use of opengl calls within my code efficient and legal
.i mean(no leakage or behind the scene complications)?

3-am i deleting and deselecting the rendering context
in the right place(case 68) or should it be in WM_CLOSE msg?
i have a bug in my winzip so i couldnt zip the code so i send you
the main.c this way you see for yoursef the big picture
. there are 6 other side files & functions needed to execute the program ,that i wont put here due to size. any way the parts about opengl are in 5 different sections headers, WINMAIN, WM_CREATE, WM_SIZE,
WM_COMMAND , case 67 & case 68(to open and close the
opengl window.
//by the way the opengl code sketeton is mainly from opengl game programming book by kevin hawkins .so i stole it.

again ,sorry about the size.
