Hi,
I am developing a application in which I need to draw the some text and graphics on the view. I can do this in OnPaint as well as in OnDraw. But when one should use OnPaing and when OnDraw()? What is difference between OnPaint and OnDraw?
Regards,
Hemant Kulkarni.

OnDraw() is ultimately called by OnPaint(), as you can find inside MFC sources:
void CView::OnPaint()
{
CPaintDC dc(this);
OnPrepareDC(&dc);
OnDraw(&dc);
}
There you can also see what happens inside OnPrepare().
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

In the structure of MFC,OnPaint is the member function of Cwnd,OnDraw is the
member function of CView

OnPaint() belongs to CWnd and handles the WM_PAINT message, while OnDraw() belongs to CView and is virtual.

Which is the best way to create a thread.
1> AfxBeginThread()?
or
2> deriving a class from CWinThread and calling ->CreateThread?

From the docs...
"Instead of calling AfxBeginThread, you can construct a CWinThread-derived object and then call
CreateThread. This two-stage construction method is useful if you want to reuse the CWinThread
object between successive creation and terminations of thread executions."
Which is better for YOU?

You need to delete entry for save menu from accelerator table in resources.

Though I'm not very clear, what you are asking. What user selection you are talking about ?
You can use CWnd::SetFont for setting font.

This[^] link should help. AFAIK there are no ready made API's for this purpose. You will have to follow certain sequential steps for Updation of existing resources.
For eg:
FindResource
LoadResource
LockResource
BeginUpdateResource
UpdateResource
EndUpdateResource
FreeLibrary
