Hi, I am writing an app in which I need to retrieve the mouse coordinates
even when it mouse is outside the main frame. How do I do it? Thanks!

Have you tried calling GetCursorPos?
If you want to know when the mouse is moving I think you'll need to
use a hook - have a look at SetWindowsHookEx WH_MOUSE.

IN addition to David's answer, you have not stated the problem you are trying to solve.

For example, in doing certain actions such as "rubber-band lines", you are operating in a
mode where you need to track the mouse, even though it is outside the bounds of the
window. This is best done by using SetCapture to capture the mouse during the mouse-down
actions. These algorithms are well-documented (see the "Scribble" app, the MFC trainging
app, which goes into great detail about this).

You did not say under what conditions you need to actually know where the mouse is, so in
addition to the "rubber banding" issue (including highlighting areas of the window, etc.)
you did not state what you are trying to accomplish; do you KNOW, by some means, when you
should look, or do you need to track the mouse, even though it is being used in some other
app.

Take a look at my hooks article on my MVP TIps site.
