CString Filepath;    CFileDialog dlg (TRUE); if(DLG. DoModal () = =IDOK) {Filepath=dlg.    GetPathName (); }    Char*path; Path=Filepath.getbuffer (Filepath.getlength ()); Cvcapture*cap; Iplimage*frame; Const CharESC = -; Cvnamedwindow ("Camera", cv_window_autosize); if(Cap =cvcreatefilecapture (path)) {          while(frame = cvqueryframe (CAP))! =0&&Cvwaitkey ( -) !=ESC) {Frame=cvqueryframe (CAP); Cvshowimage ("Camera", frame); } cvreleasecapture (&cap); /*cvreleaseimage (&frame); * Note that this cannot be released, the release will be wrong*/Cvdestroywindow ("Camera"); }
