add meesage map of OnSetCursor in the parent window.
afx_msg BOOL OnSetCursor( CWnd* pWnd, UINT nHitTest, UINT message );
the pWnd is the window under the point, you can get the ID of the window.
pWnd->GetDlgCtrlID() if it equal to the ID of the button,you call pWnd->SetWindowText("in_text"); to set the caption of the window(button).by this you can know when the mouse move into the range of the botton .

but how can you know the cursor is move out of the range of the button,
you need add a tag ,when the mouse move into ,you set it to be TRUE and you need not to call SetWindow("in_text") again when the tag is TRUE.
if you get the ID is not equal to the ID of the button you need to set the tag to FALSE and set button caption at the same time. at the next time you find your mouse is out of the button you will need not to set the caption again.
