CWnd::OnNcHitTest
The framework calls this member function for the CWnd object that contains the cursor (or the CWnd object that used the SetCapture member function to capture the mouse input) every time the mouse is moved.
afx_msg LRESULT OnNcHitTest(
CPoint point
);
Parameters

Remarks
Notes
This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
