I am trying to create a software for collaborative browsing(two person
browsing together), so there will be a browser(which i m creating) on both
the sides and in that browser I want to display a mouse cursor which will
represent the other person's cursor, so this cursor is what I want to draw
somehow!
that cursor will also move according to the coordinates received from the
other person's browser.

More or less yes. What is it exactly that you are trying to accomplish? Are
you loading a random page and then want to draw on it?

It is not going to be easy, if possible at all. If you want to draw


CHtmlView is a CFormView that has a browser window inside of it that
takes
up the entire area of the CFormView (m_wndBrowser).

All the drawing is done by and in that control. You will be fighting
with
control.

In order to draw something in that window you will have to replace that
control with your own so that you can catch its WM_PAINT message. This
means that you have to create your own CHTMLView class from scratch, and
instead of using CWnd as the base for m_wndBrowser, you can use CMyWnd
derived from CWnd which can catch the WM_PAINT message and do your own
drawing.
With all that said, I'm not sure if the browser control will simply paint
over what you have painted.

You might also be able to subclass the m_wndBrowser using SetWindowLong,
to
change it's default window proc.
