I'm not sure what you mean here, but VFP forms have their own window handle. There are two ways to retrieve it: 1.) Via API calls (which can be tricky); 2.) Foxtools: lnhwnd = _WhTohWnd(_WFindTitl(Form.Caption)). The latter, of course, requires that the library be loaded. Second, both it and the API call method can return the wrong value if forms with identical captions are present.
