The framework calls this member function when the cursor hovers over the client area of the window for the period of time specified in a prior call to TrackMouseEvent.

afx_msg void OnMouseHover(
    UINT nFlags, 
    CPoint point

NoteNote

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.

This method is supported in Windows Vista and later.

Additional requirements for this method are described in Build Requirements for Windows Vista Common Controls.
